   Number 1: Saline or Balanced Fluids? What PRoMPT BOLUS Means for Pediatric Sepsis

   In children with septic shock, does the choice between balanced crystalloids and 0.9% saline actually matter? This episode reviews the composition and physiologic differences between commonly used crystalloids, summarizes the 2026 PRoMPT BOLUS trial, and discusses how its findings fit with the updated Surviving Sepsis Campaign pediatric guidelines. We also consider the trial’s limitations and what the results mean for fluid selection at the bedside. Learning Objectives By the end of this episode, listeners should be able to: Compare the composition and physiologic effects of 0.9% saline and balanced crystalloids used for pediatric fluid resuscitation. Summarize the design and major findings of the PRoMPT BOLUS trial. Describe important limitations of PRoMPT BOLUS when applying its results to children with septic shock. Apply current evidence and 2026 Surviving Sepsis Campaign recommendations when selecting crystalloid fluids for pediatric septic shock. References Weiss SL, Peters MJ, Oczkowski SJW, et al.

As always, I’m your host, Brad Sobolewski, and today we’re gonna talk about which fluid we should use when managing a septic pediatric patient. So when we resuscitate a child with septic shock, the major decision is usually not whether to give crystalloid, but which crystalloid to give. And for a long time, there’s been a gradual shift towards balanced fluids such as Lactated Ringer’s or Plasma-Lyte, largely because they are more physiologic and produce less hyperchloremia than normal saline. The question’s always been whether those biochemical differences actually translate into better clinical outcomes. That is the question that a study called PRoMPT BOLUS was designed to answer. So before getting into the trial, it’s worth briefly reviewing what these fluids actually contain. So normal saline is 0.9% sodium chloride. It contains one hundred and fifty-four milliequivalents per liter of sodium and a hundred and fifty-four milliequivalents per liter of chloride. The chloride concentration is substantially higher than plasma. Balanced crystalloids contain less chloride and have some other electrolytes and a buffer. Lactated Ringer’s contains approximately a hundred and thirty milliequivalents per liter of sodium, one hundred and nine of chloride, four of potassium, a small amount of calcium, and lactate as a buffer. Plasma-Lyte contains approximately one hundred and forty of sodium, ninety-eight of chloride, five of potassium, magnesium, and acetate and gluconate as buffers. The concern with normal saline is that the large chloride loads can produce hyperchloremic metabolic acidosis. There’s also been concern about adverse effects on renal blood flow and kidney function. Balanced fluids are designed to more closely approximate plasma composition, so the hypothesis has been that they might reduce kidney injury. That hypothesis has been supported by physiologic data and by some adult studies, although pediatric evidence before PRoMPT BOLUS was limited and inconsistent. The 2026 Surviving Sepsis Campaign Pediatric Guidelines recommend crystalloids over albumin for initial resuscitation and conditionally suggest balanced or buffered crystalloids over 0.9% saline in children with septic shock who require fluid boluses. Importantly, that recommendation is based on very low-certainty evidence. Balanced options again include Lactated Ringer’s, Hartmann’s solution, or Plasma-Lyte. If balanced fluids are not readily available, saline remains an acceptable alternative. Saline may also be preferable in some specific situations like significant hyponatremia or concern for increased intracranial pressure. For children in resource-abundant settings, the general approach is still ten to twenty mLs per kilo per bolus with reassessment after each bolus, potentially up to forty to sixty mLs per kilo in the first hour if perfusion remains abnormal and there are no signs of fluid overload. Now, PRoMPT BOLUS, the full name of which is the Pragmatic Pediatric Trial of Balanced versus Normal Saline Fluid in Sepsis, was an international randomized pragmatic trial designed to specifically compare the two fluid strategies in children with suspected septic shock. The final trial enrolled nine thousand and forty-one children from two months to younger than eighteen years across forty-seven emergency departments in five countries. Children were randomized to predominantly balanced crystalloid or predominantly 0.9% saline, and the assigned fluid strategy was used for bolus and maintenance crystalloid during the initial treatment period. The balanced fluid arm was not a single product. Depending on the site, children could get Lactated Ringer’s, Hartmann’s solution, or Plasma-Lyte. That’s important when interpreting the study. PRoMPT BOLUS was really testing a strategy of predominantly balanced crystalloid versus a strategy of predominantly saline use rather than comparing LR versus saline alone, though LR was the most commonly used one. The primary outcome was something called MAKE30, M-A-K-E thirty, or major adverse kidney events within thirty days. This was a composite outcome that included death, new renal replacement therapy, or persistent kidney dysfunction. That choice of outcome is useful because the biologic rationale for balanced fluids has always centered largely on kidney protection. The investigators were therefore asking whether the lower chloride exposure associated with balanced fluids translated into clinically meaningful renal benefit. So what was the result? Well, the spoiler is that the answer was no. So MAKE30 occurred in three point four percent of children receiving balanced fluids and three percent receiving saline. The relative risk was one point one with a ninety-five percent confidence interval from point eight eight to one point four. There were also no significant differences in death, new renal replacement therapy, persistent kidney dysfunction, or hospital-free days. In practical terms, balanced crystalloids did not improve the major patient-centered outcomes the trial was designed to measure. There were clear biochemical differences between the groups. Hyperchloremia occurred in thirty-one point four percent of children receiving balanced fluids compared with forty-nine percent with saline. Hypernatremia was also less common with balanced fluids, one point eight versus three point one percent. Hyperlactatemia was slightly more common in the balanced fluid group, nineteen point eight compared with sixteen point seven percent. So the fluids behaved differently in the ways that you would expect physiologically. Balanced crystalloids clearly reduced hyperchloremia, but that difference did not translate into fewer major kidney events, less dialysis, shorter hospitalization, or lower mortality. There are several limitations to this study worth keeping in mind. The first is that this was a broad emergency department population with suspected septic shock, not a study limited to children with the most severe forms of shock. Only a minority of patients required vasoactive medications, and overall mortality was low. The results are therefore most applicable to the typical child with suspected septic shock receiving early ED resuscitation. They do not completely answer whether fluid composition might matter more in a smaller subgroup of children receiving very large fluid volumes or prolonged resuscitation. The second limitation is that the event rate for MAKE30 was lower than expected. When the trial was designed, investigators anticipated an event rate of about six percent in the saline group. The observed rate was closer to three percent. That means there were fewer outcome events than anticipated, which reduced the ability to detect a very small treatment effect. So the trial makes a large benefit from balanced fluids unlikely, but it can’t exclude a small or subtle difference. A third limitation is that the balanced fluid group included several different solutions. Lactated Ringer’s, Plasma-Lyte, and Hartmann’s are all considered under the umbrella of balanced crystalloids, but they’re not chemically identical. The study therefore supports the broader conclusion that a balanced fluid strategy is not superior to saline for most children in this setting, rather than providing equivalence between any single specific balanced solution and saline, even though Lactated Ringer’s is used far and away most often. The trial was also intentionally pragmatic, which means that there was some crossover between fluid types. Adherence was defined as receiving at least seventy-five percent of crystalloid as the assigned fluid rather than requiring exclusive use of one fluid. That could reduce the ability to detect a small treatment effect, but it also makes the study more reflective of real clinical practice. The investigators themselves described the trial as a comparison of predominant rather than exclusive use of balanced crystalloids versus saline. Finally, the trial was open label, so clinicians knew which fluid the child was receiving. That introduces the possibility of treatment bias, though the primary outcome relied on relatively objective measures. A substantial proportion of children also did not have a measured baseline creatinine, so baseline kidney function sometimes had to be imputed using age- and sex-based values. That’s worth remembering because persistent kidney dysfunction was part of the primary composite outcome. Taken together, I think PRoMPT BOLUS makes the bedside decision simpler. Balanced fluids remain a completely reasonable and defensible choice. They cause less hyperchloremia, and there’s no reason to abandon them if they’re already part of your usual resuscitation fluid strategy or your order sets. At the same time, the largest pediatric randomized trial now shows no improvement in major kidney or mortality outcomes compared with normal saline. So if you use saline at your local hospital, that’s okay too. The 2026 Surviving Sepsis Campaign still conditionally favors balanced crystalloids, but that recommendation is based on very low-certainty evidence. So PRoMPT BOLUS adds important randomized data suggesting that for most children with septic shock, either crystalloid strategy is reasonable. The practical takeaway is that the choice of crystalloid is probably less important than getting the resuscitation itself right. Give 10 to 20 mLs per kilo when a fluid bolus is indicated, reassess frequently, watch for improvement in perfusion and for signs of fluid overload, and move to vasoactive support when fluid alone is not correcting the shock. Balanced crystalloids will produce less hyperchloremia. Normal saline will produce more. In PRoMPT BOLUS, that biochemical difference did not translate into a difference in kidney injury, dialysis, or mortality. For most children with septic shock, balanced fluids are fine, normal saline is fine, and timely, thoughtful resuscitation matters much more than which bag is hanging. I hope you found this episode on fluids for sepsis in children helpful and that you’ll be able to take this knowledge back to the bedside the next time you work in the emergency department.

   Number 2: Night Terrors

   Night terrors are dramatic but benign episodes that can leave caregivers frightened and confused. In this episode of PEM Currents: The Pediatric Emergency Medicine Podcast, we explore the clinical features of night terrors, how to differentiate them from other nocturnal events, and when to consider further evaluation such as polysomnography. We also discuss management strategies that center on sleep hygiene, reassurance, and safety, with a special look at the role of scheduled awakenings and when medication is appropriate. Learning Objectives By the end of this episode, listeners will be able to: Describe the typical clinical presentation and age range of children with night terrors. Differentiate night terrors from other parasomnias and nocturnal seizures based on clinical features and timing. Discuss non-pharmacologic and pharmacologic management strategies for night terrors, including when to consider polysomnography. References Petit D, Touchette E, Tremblay RE, et al.

Available from: https://www.ncbi.nlm.nih.gov/books/NBK493222/ Transcript This transcript was provided via use of the Descript AI application Welcome to PEM Currents, The Pediatric Emergency Medicine Podcast. As always, I'm your host Brad Sobolewski. In this episode, we're talking about night terrors, also known as sleep terrors. A dramatic, confusing, and often terrifying experience for caregivers to witness. But they're usually benign and self-limited for the child. Kind of like a lot of the things in childhood actually, what are we gonna talk about? Well, what are night terrors? How do we diagnose them? How to differentiate them from seizures or other parasomnias key counseling for parents in the emergency department, when to refer for sleep studies or neurology evaluation, and what role, if any, medications play. So let's start with talking about what night terrors actually look like. They're part of a group of disorders called non REM parasomnias, which also includes sleepwalking and confusion arousals. They are not nightmares and they are not signs of psychological trauma. Children experiencing night terrors typically sit up suddenly during sleep, scream, cry or appear terrified. Show signs of autonomic arousal. So rapid breathing, tachycardia, sweating. They're confused or inconsolable for several minutes and they have absolutely no recollection of the event the next morning. These events usually occur in the first third of the night when children are in deep, slow wave sleep, so stage N three, and they can last five to 15 minutes, but trust me, they seem to last much longer to observers. Night terrors occur most commonly between ages three and seven with a peak around five years of age. They're rare before 18 months and unusual after age 12. Preschool aged children are most affected because they spend more time in deep, slow wave sleep. They have more fragmented sleep architecture, and they may not have fully developed arousal regulation mechanisms. Episodes can start as early as toddlerhood, especially if the child has a family history of parasomnias. So like sleep, walking night terrors or other things, sleep deprivation or stressful life events like starting daycare or a new sibling or a move, although less common, older children and even adolescents can experience night terrors, especially in the context of stress, sleep deprivation or comorbid sleep disorders like sleep apnea. Why do they happen? Well, they're usually due to incomplete arousal from deep sleep, so the brain is essentially stuck between sleep and wakefulness. Factors that increase the risk of frequency of night terrors include again, sleep deprivation, recent illness, stress, or anxiety. Sleep disordered breathing, or a family history of parasomnias, there's a real strong genetic component. Up to 80% of children with night terrors have a first degree relative with similar episodes. The diagnosis is entirely clinical and based on history. You should ask parents, what time of night did these episodes occur? Is the child confused, frightened, or hard to wake? Is there amnesia the next day so they don't remember the event? And are the movements variable or stereotyped? Sometimes parents will video record these, and that can really help us clarify the episodes when we're in the emergency department. You definitely do not need labs or imaging in a typical presentation. I think parents are often seeking an explanation for why their child looks so freaky. In my experience, just telling them that it's a night terror and that it's benign and providing reassurance on how healthy their kid is, is more than enough. Now, not all nighttime events are sleep terrors. You should consider neurology referral and video polysomnography or sleep studies with extended EEG when onset is very early, so younger than 18 months or late in childhood. So older than 12 or 13 episodes occur outside of the first third of the night. Again, find out when the kid went to bed. And do math. The first third of the night is the first 33% of their typical sleep time. The events are brief clustered or stereotyped. The movements are repetitive, focal or violent. If kid just moving just their right arm. That's not a night terror. Often the movements will look fearful and they'll be sort of disorganized. Rhythmic movements don't typically happen in night terrors, and there's a recent injury. The child has excessive daytime sleepiness, or there's some developmental regression or abnormality. All those are red flags. Differentiating from nocturnal frontal lobe epilepsy can be tricky. Nocturnal frontal lobe epilepsy events are usually short. Highly stereotyped. They have abrupt onset and offset, and they may include dystonic or tonic posturing. So if the family has a video of this, that can be really helpful using a good clinical history. Video recordings in EEG generally distinguish night terrors from these forms of epilepsy. But let's be honest, most of the kids you see in the ED with a typical presentation of night terrors are just night terrors. These events are really scary and we are gonna see them in the emergency departments, and so your first goal is to just reassure the family. The events are not harmful. The kid isn't aware that they had them, and the child suffers no ongoing psychological harm. That doesn't mean that the parent isn't freaked out or that nervousness doesn't linger. You wanna avoid sleep deprivation If possible, counsel families on age appropriate bedtimes and naps. Stick to a routine consistent bedtime routines. Reduce sleep fragmentation, which is a known risk factor for children with frequent or predictable night terrors. Try waking them 15 to 30 minutes before the usual episode happens. So I've seen lots of kids with frequent night terrors, and they usually happen around the same time at night. And you wanna do this, this 15 to 30 minute awakening before the usual episodes each night for about two to four weeks. That's labor intensive as a parent, but it can help these awakenings interrupt the sleep cycle and break the pattern. Keep kids safe. Use baby gates, door alarms. Make sure windows are locked, don't put younger kids in bunk beds and remove sharp obstacles or objects near the bed. So if they've got a pointy ended nightstand, oh, that's just something for the kid to fall into or smack against. Do we ever use medications for night terrors? Well, almost never. You know, pharmacologic therapy such as low dose benzodiazepines or tricyclic antidepressants is really only reserved for severe episodes. Kids with substantial risk for injury or disruption of the family life or school in a substantial way. I'm not gonna make that call in the emergency department. And these are sleep specialist referral guided therapies. You also wanna consider evaluating children for comorbid sleep disorders, especially in recurrent night terrors, like obstructive sleep apnea, restless leg syndrome. This may worsen the parasomnias. For kids in which you're unsure, polysomnography can be used. This is an overnight sleep study that monitors brainwaves via EEG, eye movements, muscle activity, heart rhythm, breathing effort, and airflow and oxygen saturation. But it's also done in a hospital and not during the kid's usual sleep routine. So most children that have night terrors, if you get the right history, you can make the diagnosis clinically and the kids don't need any expensive or expanded testing to get to the bottom of things. Alright, take home points for this brief episode. Night terrors are common, especially in preschool aged children. They occur in non REM sleep in the first third of the night. The episodes are very dramatic, but they're benign and children don't remember them. But trust me, parents do. The diagnosis is clinical. No labs or imaging are needed unless there's atypical features. You should reassure families, promote sleep hygiene and use scheduled awakenings for frequent and recurrent cases, and refer for sleep studies and or neurology of episodes or violent stereotyped, or suggest nocturnal seizures. Thanks for listening to this episode. I hope you found it educational about a topic that you will encounter in the emergency department. As with many things in children that are scary, there's a benign explanation and parents are just looking to know that their kid's gonna be okay. Often doing a thorough history in physical and really listening to the parents' concerns and then providing useful information is all you gotta do. That's why pediatrics is great. If you've got feedback on this episode or there's other common topics you'd like to hear about, send them my way. If you enjoyed this episode and think that other people should listen to it, share it with them. More listeners means more learners.

   Number 4: Inhalant Misuse: From Glue to Galaxy Gas

   In this episode of PEM Currents: The Pediatric Emergency Medicine Podcast, we explore the complex and often underrecognized issue of inhalant misuse. From the early days of glue sniffing to the recent rise of nitrous oxide misuse, fueled by brands like Galaxy Gas and viral trends on TikTok and Instagram, inhalant misuse has evolved into a growing concern among adolescents. We’ll dive into the clinical presentations, including acute and chronic symptoms, the dangers of “sudden sniffing death,” and the specific risks associated with nitrites, hydrocarbons, and nitrous oxide. Learn how to recognize and manage cases in the emergency department, ask the right questions to uncover inhalant use, and provide critical resources for prevention and support. Whether you’re a seasoned pediatrician or new to emergency medicine, this episode offers essential insights into tackling this hidden epidemic. Learning Objectives By the end of this episode, listeners will be able to: Recognize the clinical signs and symptoms of inhalant misuse, including acute intoxication and long-term complications. Differentiate between the risks and toxic effects associated with specific inhalants, such as hydrocarbons, nitrites, and nitrous oxide.

As always, I’m your host, Brad Sobolewski, and today we’re diving into an important topic, inhalant misuse, with a special focus on nitrous oxide. Welcome Recently, there’s been a concerning rise in recreational use of nitrous oxide, often referred to as Galaxy Gas, which is actually a brand name, which has become synonymous with flavored nitrous oxide products. Even as that brand, Galaxy Gas, is being phased out of the market, its legacy persists, fueled in part by its viral presence on social media platforms like TikTok and Instagram. So, this episode is going to break down the symptoms, clinical presentations, and management of inhalant misuse in children and adolescents with a specific eye on how these trends are shaping a new wave of cases presenting to the ED across the globe. So, what are inhalants? Well, these are volatile substances that you’re not meant to breathe in. They produce vapors, which, when you inhale them, cause psychoactive effects. They include everyday household items like glue, paint thinner, and gasoline, as well as recreational substances such as nitrous oxide, often referred to as whippets or galaxy gas. Interestingly, when these are sold, either online or in physical stores, they’re marketed As additives to make your own whipped cream at home. The people that sell them in stores are told to specifically not refer to them as whippets or to refer to them as a drug. Oh no, they’re only for cooking. The customers and the people selling them know otherwise. Anyway, the recreational use of nitrous or whippets, it’s been around since the late 18th century, uh, when it was used in laughing gas parties among the immigrants. English elite. Fast forward to today, and nitrous remains one of the most commonly misused inhalants. It’s evolved from its medical and industrial applications to a recreational substance with a significant cultural footprint. And let’s face it, the prevalence of this inhalant misuse is concerning. In the US, about 11 percent of high school students have used inhalants at least once. And what’s striking is that inhalant use peaks in younger adolescents, particularly those in like 7th through 9th grades, middle schoolers. making it one of the earliest substances that are misused among young people. So, these inhalants are often used through sniffing, huffing, or bagging. Sniffing involves inhaling the fumes directly from the container. Huffing uses a cloth soaked with the substance. And bagging, or perhaps ballooning, involves inhaling fumes from a bag or balloon placed over the nose and mouth. So you decant the substance from the canister into a balloon, and then you inhale that into your mouth. The latter dramatically increases the risk of asphyxia. The mechanism of action is rapid and profound. These substances are absorbed through the lungs and distributed to the brain, where they act on GABA and glutamate receptors. The primary effects are euphoria, dizziness, and disorientation. They’re felt within seconds and last 15 to 30 minutes or less. And. Patients that use these will repeatedly use it throughout the day. You can either get one little individual canister of nitrous, or a big canister which costs about 120 to 120. Repeated use can sustain that intoxication. So the symptoms of inhalant misuse are important to recognize. So first and foremost are the neurological symptoms. Euphoria, ataxia, disorientation, and slurred speech are common in acute intoxication. Chronic misuse can be devastating and unfortunately we don’t know how much, or how long, or how frequent leads to these symptoms. But nevertheless, they’re pretty darn bad. It includes cerebellar dysfunction, peripheral neuropathy, and toxic leukoencephalopathy, which manifests as white matter degeneration visible on MRI. Basically, misuse of this stuff can paralyze you. The cardiovascular symptoms include sudden sniffing death syndrome, which is the generation of a fatal arrhythmia, which is particularly dangerous with halogenated hydrocarbons. Pulmonary symptoms include hypoxia, reactive airway dysfunction, and in severe cases, pulmonary edema or even a pneumothorax. Glue sniffer’s rash is a hallmark skin finding. It presents as erythema and inflammation around the mouth and nose. and nose. Chronic users may also see weight loss, abdominal pain, nausea and vomiting, and metabolic abnormalities like hypokalemia and acidosis, especially if they’re misusing toluene, which is fortunately less common. Further complicating matters is that each inhalant has its own special risks. Hydrocarbons, again found in solvents and glue, can lead to cranial neuropathy, cerebellar dysfunction, and cardiac arrhythmias. Chronic misuse of these results in profound hypokalemia and metabolic acidosis. Nitrous oxide, so whippets or galaxy gas, interferes with vitamin B12 metabolism, so it can lead to polyneuropathy, myelopathy, and hyperhomocystinemia, which increases the risk of venous thromboembolism. Nitrites, which are known as poppers, can cause intense vasodilation and methemoglobinemia. with symptoms ranging from headache to cyanosis and seizures. So management, unfortunately, of inhalant intoxication is primarily supportive. Stabilization, you have to ensure that the patient is removed from the exposure source and administer 100 percent oxygen if they’re hypoxic. If the patient is unconscious and in a tachyarrhythmia, the treatment is electricity! Amiodarone or lidocaine on the palsgar rhythm and avoid catecholamines like epinephrine unless the patient’s in cardiac arrest. For nitrous oxide neurotoxicity, administer high dose vitamin B12 intramuscularly or subcutaneously. I would consult a toxicologist because I know that this is rare. And if you have a patient with methemoglobinemia, chances are you’re actually taking a board test, but you would treat that with IV methylene blue. In cases of toluene misuse, monitor and correct the electrolyte imbalances carefully, avoid dextrose, which can actually worsen the hypokalemia. Again, I would call a toxicologist for help from this, because fortunately, it’s very rare. And listen, this problem isn’t going anywhere. So pediatricians, Educators and parents all play a crucial role in prevention. Frankly, these should not be so accessible. They should not be able to be sold easily online or in physical smoke shops. Also, we need to advocate for federal regulation on these as controlled substances, because currently right now they’re not. Everybody knows the dance that the retailers play in saying, Oh yeah, you can use these to make whipped cream at home, but they are marketed with with flavoring in brightly colored containers and they are very attractive to young children. They’re piggybacking off the same strategies that made vaping and vape cartridges so popular. Students should be educated about the dangers of inhalants. That means both local advocacy in schools and in medical care settings, but also using some of the same techniques that made getting high off these popular, like social media. We’ve got to reduce access. and curiosity. Schools should definitely replace solvent based products with safer alternatives and monitor students for signs of misuse. For those already misusing inhalants, referral to a substance use disorder program is essential. Chronic complications often resolve with cessation, but addressing coexisting mental health problems and comorbidities such as depression and suicidality is equally important. Okay, I know that that was just a whiff of a topic that you may be only a little bit familiar with. But trust me, you’ve probably met a patient That’s huffing or inhaling, and you just haven’t known it. So it starts with asking patients about what they’re doing. A good old heads exam. So when asking patients about inhalant misuse, it’s important to create a non judgmental and supportive environment. Start with broad, open ended questions, and normalize them. Say that this is something that you ask all patients about. Ask about substance use, like vaping or alcohol, and then introduce inhalants by mentioning specific examples, such as sniffing glue, huffing spray paint, or using nitrous oxides like whippets or galaxy gas. Again, normalize that conversation by acknowledging curiosity or peer influence, especially on social media. And, if they do disclose use, ask gently about frequency, Context and any symptoms like dizziness, headaches, or worse, emphasize that your goal is to support their health, not to judge or punish and provide reassurance and resources if needed. Thank you for listening. Inate misuse is often overlooked, especially in pediatric emergency care settings, but if you’re vigilant and you’re informed, you can better serve our patients and manage complications.

   Number 5: ‘Twas the Night Before Christmas (in the Pediatric Emergency Department)

   In lieu of a traditional episode this holiday season I wanted to share a reading of the Pediatric Emergency Medicine version of a famous Christmas poem. Transcript ‘Twas the night before Christmas, and I’m working a shift, The symptoms were varied, the pace was quite swift. The screens glowed with orders, the rooms filled with care, In hopes that discharge summaries soon would be there. The nurses were moving with hustle and speed, While families recounted each child’s urgent need. And I at my computer, my coffee in hand, Prepared for the onslaught that none could have planned. When out in the lobby there arose such a clatter, I sprang from my chair to see what was the matter. Away to the triage I flew like a flash, Dodging spilled apple juice and a child with a rash. The ambulances were wailing, the scene quite a sight, As the complaints rolled in on this hectic night. When what to my weary eyes did appear, But a febrile infant, his parents in fear. A nursemaid’s elbow in need of a tug, And a kid with a cough wrapped tight in a hug. A forehead lac with blood streaming red, And a teen who proclaimed, “I think I’m half-dead!” With quick-thinking teamwork, the cases we tamed, And I whistled and shouted and called them by name: “Now flu! Now croup! Now migraines and pain! On seizures! On sepsis! That ankle is sprained! To the trauma bay stat, through triage with speed, Move quickly, move calmly, and meet every need!” As the snow flakes that fall when wild winter winds fly, We hustled and triaged as new patients arrived. And then, in a twinkling, I heard down the hall, The sound of retching – a vomiting call. Ondansetron ordered, the nurse prepping the dose, I saw a pale toddler, looking morose. He was sick from his tummy to the tip of his nose, And the sounds of his misery steadily rose. His eyes were all sunken, his cheeks far too pale, But a popsicle bribe led to a triumphant exhale. The shift rolled along with splints left and right, Broken forearms galore on this holiday night. And ketamine laughter soon filled the air, As a lac repair finished with great skill and care. Abdominal pains brought more to the bays, With parents repeating, “He’s been sick for days.” A scan ruled out danger, the appendix intact, While the next patient arrived with an asthma attack. The hours wore on, the crowd didn’t cease, Yet amidst all the chaos, we found moments of peace. A mom’s grateful smile, a child’s sleepy yawn, Reminded us why we keep carrying on. So I sat at the computer and typed one last note, Cleared my inbox of tasks and the orders I wrote. And I heard myself whisper as I turned off the light, “Merry Christmas to all, and to all a calm night!”
