Anaesthesia Archives - obsgynaecritcare

You have attempted to top up an epidural for a category one caesar for fetal distress. The block seems adequate but once the surgeons enter the abdomen your patient complains of significant pain and you decide to convert to general anaesthesia. You perform an RSI with propofol and rocuronium. After intubation she has a heart rate of 130 and an NIBP of 155 / 90. Your registrar asks “why didn’t we give her any opioid?” and you patiently explain that we avoid opioids until after delivery because we don’t want them to cross the placenta and to cause respiratory depression in the neonate……………but is this always true???

Hi everyone,

Join Jacob and I as we discuss the recent literature surrounding this topic. What is the evidence? What about the short acting opioids such as alfentanil & remifentanil? What are the advantages / disadvantages of using an opioid and what are the downsides of not using opioids?

Join Sarah & Declan as we continue our series covering the ANZCA final exam curriculum for obstetrics across four episodes. This second episode covers complications in labour and delivery including management of postpartum haemorrhage.

We hope this resource will be helpful for everyone, but especially those of our trainees preparing for the final exam. To get the most out of it, we suggest regularly pausing the podcast to answer each question yourself, before listening to our answers. Of course there is much more detail expected in the exam, but if you can answer all these questions confidently, we think you’ll have a great chance.

If you find this podcast helpful, or have suggestions for future episodes in this series, please send us an email to let us know.

Hi everyone

Dexmedetomidine, is both a difficult word to pronounce correctly in casual conversation but also a useful pharmacological tool in many different situations.

This week I am joined by one of our fellows Dr Han Lu to discuss dexmedetomidine, it’s history, it’s basic pharmacology and then more specifically it’s use in different clinical situations where it may be useful in obstetrics and gynaecology.

Thanks Han for a great Tuesday talk and a very informative podcast!

Hypothetical Case:

You finish injecting the spinal anaesthetic for your patient who has come for an urgent caesarean section. She has pre-eclampsia and her blood pressure just before you started was 180/100.

Just after lying down she starts vomiting and unfortunately the non invasive blood pressure cuff is going up and down but not giving you a number – she is shaking and can’t stop moving around. Is she vomiting because of hypotension, should you give her a bolus of phenylephrine? What if she is actually still hypertensive – you don’t want to push her BP over 200. Wouldn’t it be great if you had a beat to beat continuous display of her BP – maybe you should have placed an arterial line before starting. Are there any other options that might have been helpful???

Hi everyone,

This week I am joined by John to discuss continuous non-invasive blood pressure monitoring. Many of these technologies have actually been around for a number of years now, but despite this don’t seem to be in commonplace usage. There does seem to be a recent renewed interest in re-evaluating these technologies. How do these technologies work? How accurate are they? Have there been any improvements? What are the economics and costs?

Thanks John for all your hard work researching this topic!

The post 150 Tilting the tables: a discussion of the evidence for routine table tilt during elective caesarean appeared first on obsgynaecritcare.

Hypothetical Case:

You are called to MFAU to see a woman who has just arrived via RFDS (royal flying doctor service)

She is a 23 y.o indigenous woman from the Kimberley in the far north of WA. She is 33/40 G1P0 complex social history and possible substance use disorders

She has PPROM (pre term premature rupture of membranes) and suspected early chorioamniotis and has been given antibiotics / nifedipine and a few litres of crystalloid fluid during the flight.

The obstetric team have evaluated her – she has small for gestational age baby, and is complaining of dyspnoea.

Her observations are: HR 110, NIBP 124/60, SpO2 91% on room air, T38.1

Her bloods are relatively normal except for an unexpected high BNP.

You do a focussed bedside transthoracic ECHO and unexpectedly see on the PLAX (parasternal long axis view) a classical hockey stick / domed appearance of severe mitral stenosis. She also has Pulmonary B-lines (indicating pulmonary oedema) and a flattened interventricular septum, very large atrium & doppler through the tricuspid valve confirms severe pulmonary hypertension. 

The team decides she would be better cared for in a hospital with cardiothoracic services – however she suddenly becomes more breathless – SpO2 86% on oxygen, NIBP 80/40 HR 125, and there is a prolonged foetal bradycardia…………………

Hi Everyone,

This week I am joined by Dr Clinton Ellis, a cardiothoracic anaesthetist based in Sir Charles Gairdner Hospital, and Graeme. We discuss the management of rheumatic heart disease in pregnancy – a challenging condition which unfortunately is still relatively prevalent amongst indigenous women here in Australia.

This was a wide ranging discussion so I have decided to split this into two 40min episodes. Even though we talk for over 80min I feel like we just scratched the surface on this! If you have any questions or comments send them through – I will try and get Clinton to answer them.

Finally a huge shout out and thank you to the Darwin based authors of the ANZCA 2023 Blue Book article on this condition: Namrata Jhummon-Mahadnac, Matthew Mathieson, and Akshay Hungenahally! See the link to their well written narrative review on this topic below:

Hi everyone,

Pain during caesarean is a very challenging and distressing event – for the patient, their partner, the anaesthetist and all the staff present in theatre.

This week we catch up with Matt Rucklidge, who recently gave a presentation on this topic at the obstetric anaesthesia meeting in London. We discuss why this has become a “hot topic” in the anaesthesia world in recent times, what is the true incidence, and many other aspects of this difficult topic.

The following is a first person narrative story from a patient with commentary from an uninvolved obstetric anaesthetist. Disappointingly from elselvier this article is unfortunately not open access but is well worth a read:

Hi everyone,

This week Declan and I sit down to discuss a novel non opioid analgesic drug recently approved for use by the FDA, suzetrigine.

What is it? How does it work? Why should we be interested in this new class of drugs and most importantly will it live up to it’s hype?
