Join us as Declan and Roger discuss the evidence for routine table tilt during elective caesarean section.   Has this changed your practice? What is your opinion on this topic? We’d love to read your emails.  As mentioned in the episode we would love to do a future episode on Q&A so if you have any questions on any topic you would like us to tackle please send them in!

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: References Australasian Anaesthesia 2023 (aka the Blue Book) – see page 39 “Obstetric anaesthesia in rheumatic heart disease – a unique perspective from the Top End” Oral vaccine could prevent rheumatic heart disease in NZ VIDEO: Researchers close to a vaccine for strep-A and rheumatic heart disease

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. References The following is a first person narrative story from a patient with commentary from an uninvolved obstetric anaesthetist.

You are called to assess a pregnant woman who presents to your hospital complaining of shortness of breath. She is 36 weeks pregnant with twins and tells you she had been getting progressively short of breath over the last month but put it down to the physical effects of the twin pregnancy in her abdomen. However last night she couldn’t get her breath lying flat, had to sleep sitting up on 3-4 pillows and feels that “it is much worse”. On examination she has a respiratory rate of 24/min, SpO2 = 92%, HR 105/min, BP 95/45 and you can hear crepitations in both lung fields. Her initial blood tests come back showing a raised plasma BNP and a bedside ECHO is done by a helpful colleague – who says “subjectively her LV isn’t contracting very well”. Hi everyone, This week I sit down with Dr Faith Njue the most qualified person here in WA to discuss the rare but important disease – peripartum cardiomyopathy. (See Faith’s Bio below). Join us in our wide ranging discussion which touches on the diagnostic challenges, demographics, proposed mechanisms and general principles involved in managing these complex patients. Thanks Faith for a great discussion! Dr Faith Njue – Bio Faith Njue graduated from the University of Western Australia and completed cardiology training in Perth. She undertook further subspeciality training in advanced heart failure/ heart transplantation at Fiona Stanley Hospital and the University of Ottawa Heart Institute in Canada. Thereafter, she undertook further fellowship in cardio-obstetrics at the John Radcliffe hospital in Oxford (UK). She has special interest in women’s cardiovascular health, heart disease in pregnancy and heart failure. Faith runs the dedicated Western Cardiology cardio-obstetrics clinic, designed to support women at risk of or with pre-existing heart conditions, through preconception counselling, pregnancy and into the post-partum period. Cardio-obstetrics is an expanding subspecialty that focuses on prevention, early detection, and appropriate management of cardiovascular disease in pregnancy. She holds public consultant positions at Sir Charles Gairdner and Fiona Stanley hospitals. She is part of the Advanced heart Failure and Cardiac Transplant team at FSH. She is the cardiology clinical lead for High Risk pregnancy at FSH. References Anaesthesia and peripartum cardiomyopathy Chapman, K. Njue F, Rucklidge M.

Hi Everyone, Join Graeme and I as we discuss two articles chosen from last months edition of IJOA (International Journal of Obstetric Anesthesia). In the first we discuss an article exploring whether the use of intermittent calf compression can reduce hypotension and vasopressor use in women undergoing caesarean section under spinal anaesthesia. The second article looks at the utility of preoperative electrical stimulation of acupressure points prior to caesarean section reduces postoperative pain and improves the quality of maternal recovery. There’s a sprinkling of our usual dad jokes at the end. For regular listeners to the show join us again later this month when we hopefully will have a couple of episodes dedicated to the management of placenta accreta spectrum and an interview with the founders of the placenta accreta service setup 7 years ago here at KEMH – see you then!
