A maternal death is always a tragic event for the mother, the child, the family and society at large. Unfortunately in some parts of the globe this is still a much too common event. Luckily for those of us living in higher resource countries it has now become relatively rare. This week Matt and I sat down together to discuss the history of maternal mortality reporting, and all the useful knowledge...

As the duty anaesthetist you are called down to the antenatal clinic by the obstetric team to see a pregnant woman with achondroplasia who is booked to deliver in your hospital. What are the anaesthetic issues which can arise in this condition? What evidence is there in the literature for the optimal anaesthetic techniques? What will you discuss with this woman and how will you counsel her? Join D...

You are called to a code blue on the postnatal ward. A 28 yr old female who is 1 day post a non elective caesarean section has just had a witnessed convulsion lasting 1-2 min. She has now regained consciousness but seems a little confused and is complaining that she “has lost vision in both of her eyes”. Her BP is 180/100, and all other vital signs are normal. What is this most likely...

Hi everyone, Join us this episode – Declan and I have scoured the literature for a few interesting articles of varying degrees of quality! We had fun discussing these articles and hopefully you will also enjoy our discussion. Hopefully we will make this a regular feature every 3-4 months! Articles Discussed 1 – Effect of Dural-Puncture Epidural vs Standard Epidural for Epidural Extensi...

You are called to labour ward to place an epidural in a nulliparous woman who is obviously extremely distressed in pain. After you sit her up to clean her back you notice she has a long scar running down the middle of her back. Between contractions she tells you she had surgery as a teenager to straighten her back…..what does this mean? Hi Everyone, Graeme regularly teaches this topic to our...

Hi Everyone, Whole blood, freeze dried plasma, refrigerated or frozen platelets…. On Oct 31st – Nov 3 Graeme, Emelyn and I attended the THOR – THUNDER conference hosted here in Perth at the Rendezvous Hotel in Scarborough. Who is THOR? In their own words: The THOR (trauma haemostasis oxygenation resuscitation) organization is a resuscitation and blood network, originating in Norw...

Hi everyone, Welcome to part 3 of a 3 part series we have put together – 3 hypothetical cases involving anaemia / patient blood management scenarios. Thanks to the two great colleagues who made these discussions with me, Dr Anastazia Keegan Head of Haematology here at KEMH and Assoc Prof Nolan McDonnell a colleague from our Department of Anaesthesia. These cases might sound familiar to any registr...

You are phoned and asked to review the venous blood gas from a woman who has just given birth in labour ward. She had a long and difficult labour and eventually required an instrumental delivery. The RMO tells you also that she was very difficult to take blood from and the tourniquet was on her arm for quite a long time. Her results show that she has a lactate of 2.5. Does this result mean she has...

Hi Everyone, “Three minutes after the administration on the spinal anaesthetic they became restless and complained of severe pain in both lower limbs and back. Their heart rate and blood pressure increased to 130bpm and 160/100 mmHg. A rapid survey of previously administered medications revealed tranexamic acid 300mg was accidentally injected into the subarachnoid space instead of 15mg of hy...

Hi Everyone, Join Siv and I as we sit down to discuss a couple of interesting obstetric related topics. The first is the pharmacology around the choice and strength of local anaesthetics used in epidural analgesia – thanks Siv. The second part we discuss a very large pragmatic study in the New England Journal of Medicine of 11000 women studying the use of tranexamic acid as a prophylaxis dur...

Hi Everyone, This week we are joined by Dr Anastazia Keegan an obstetric haematologist and the head of Haematology at our Women’s hospital here in Western Australia. Join us as Anastazia educates us about congenital bleeding disorders in pregnancy – the common ones, Von Willebrands disease and haemophilia – and how to approach a woman with one of the many uncommon ones (which wor...

Hi Everyone, This is part 2 of a discussion (see the previous episode for part 1). We have just returned from the Obstetric Anaesthesia Special Interest Group Satellite meeting held on May 3-4. I sat down two days after the meeting with Dr Matt Rucklidge (the convenor of this meeting and a colleague here at KEMH) and Prof Nuala Lucas one of the keynote invited speakers from the UK who is the presi...

You are called to a code blue medical on labour ward – a previously well nulliparous woman has just had a seizure, and now seems confused. Her observations are normal, she is not hypertensive and the CTG appears fine. She is presumed to have had an eclamptic seizure and is given oxygen, magnesium and has some urgent pre-eclampsia bloods and urine sent. The midwife states she has been trying...

Hi Everyone, In our tertiary women’s hospital here in Perth we use remifentanil PCA in labour approximately 15 times a year – and we are told that in Australian terms this is considered a “heavy user” of this labour analgesic technqiue. This week I sit down with Mike Jamison an anaesthetic fellow from Belfast spending a year with us here in Perth. When he arrived in WA we q...

You are referred a patient who needs urgent surgery and the obstetrician tells you she has some obscure medical condition which you have never heard of before. Does her condition have any implications for the safe conduct of anaesthesia? How can you find out in a timely manner what the specific anaesthetic issues are and what anaesthetics have been used safely by others in these patients before? H...

Arterial lines – let’s face it who doesn’t love them? When you have a truly sick patient these humble and often underrated devices bring so much to the table, precise control of the haemodynamics, assessment of gas exchange, blood sampling to assess coagulation, anaemia and many other parameters. There is nothing more frustrating however when these lines don’t go in easily,...

(Hypothetical case) You are called to the PACU to review a patient, who despite face mask oxygen has saturations of only 88%. She is a woman in her 50s who has just undergone a 3 hour laparoscopic hysterectomy for endometrial cancer. She has a BMI of 48, has been a smoker for 30 years, and had a chest infection 3 weeks ago. When she walked into the hospital earlier this morning she was breathing r...

Hi everyone, This week three of us sit down to discuss a great review article (and topic) – the use of TIVA (total intravenous anaesthesia) for GA caesarean surgery. For many the classic technique for a GA caesarean has been thio / sux tube then volatile & nitrous oxide. In recent years many aspects of this have started to change with propofol probably more commonly used as the i.v. indu...

Hi Everyone, You receive a phone call at 2am from a junior colleague who tells you that they are managing a code blue caesarean section and in the confusion of urgently administering a number of different medications they have just accidentally injected 10ml of cephazolin into the epidural catheter instead of the intravenous tubing. They are understandably upset and worried. (* This is a hypotheti...

Hi everyone, This week Graeme and I sit down for the first time in nearly a year and do a bit of a deep dive on the use of nitrous oxide as an analgesic in labour. We drop a few dad jokes, discuss the history of inhaled analgesics, nitrous oxide use around the world, the evidence, the environmental concerns and other interesting anecdotes. Do you have nitrous oxide on labour ward in your part of t...

Your 76 yr old patient is now two days post her laparotomy for ovarian cancer. She looks well, is starting to eat and keen to get up to the shower as well as have all the “annoying lines and tubes removed from my arms!”. Unfortunately she is still on 3ml/hr of a metaraminol infusion and everytime the nurse tries to wean it off her BP drops to 70/45….. Is there anything you can do...

Hi everyone, This week Sneha leads a discussion with both Matt and myself where we take a deep dive into how to actually perform an epidural blood patch. Even though you can’t really classify this as an uncommon procedure, as individuals we probably don’t do very many and it is hard for most of us to become experienced and “expert” (whatever that is defined as). We discuss...
