I’m back today after a little break over the exam period with our brand-new series “Neurophysiology & Pain.” The topic today is “Functional Anatomy.” I start by first going over the basic anatomy of ANS broken down further into the sympathetic and parasympathetic nervous system (02:38) followed a look at the important neurotransmitters and receptors in this pathway (13:27). Then I look at the structure and function of the blood brain barriers (25:51) as well as the production, reabsorption and role of CSF (30:28). There are a few SAQs to get through at the end both from ANZCA and CICM exams (38:11). Thanks for listening! As always if you have any feedback let me know @ anirudh@sweetdreamsanaesthesia.comToday is the first "MiniPod" where we discuss the ionic basis of automaticity the normal and abnormal processes of cardiac excitation. In other words the Slow response Action Potential vs Fast response Action Potential. I have divided these episodes into three sections: facts and knowledge, past SAQs and reviewing viva opening stems. I start with a basic review of pacemaker cells in the heart (01:48), then compare the fast vs slow AP (06:56). We look at a model answer for past SAQs (15:42) and then look at the viva stems with links to other concepts (23:09). I hope you enjoy this new structure for the Podcast and if you have any questions please email me! As always thank you for listening!

Today’s topic is a little more straightforward with very few LO’s to cover but still some important concepts. I start by first going through nerve conduction physiology (01:07) followed by understanding the difference between sleep and general anaesthesia (11:29). This leads to discussing an important topic of EEG and more specifically different types of processed EEG (19:07). As always at the end I go through the past SAQ’s (24:50). Thanks for listening!

Today’s topic is a fundamental topic when it comes to ‘Neurophysiology.’ There are more than 8 learning objectives for this topic, but they overlap quite a bit. So, I have divided this episode into two main LO’s, the first looks at ICP (02:09) and CBP (13:18). Then I briefly look at anatomy of circulation to the brain and spinal cord (30:15). Following this I look at the second main part which is spinal cord pressure (35:14). As always at the end I go through the past SAQ’s (39:07). Thanks for listening!

This is a huge topic to cover and brings us to the end of our ‘Neurophysiology & Pain’ series. Today’s topic is “Pain Physiology” and we start straight away by looking at the normal sensory pathways (01:39). This is followed by a detailed look at one the biggest LO’s being physiological mechanism of pain (11:44). After this I quickly review the progression from acute to chronic pain (32:36), physiology of neuropathic pain (37:05) and alteration in pain perception in the elderly (39:18). As always at the end I go through the past SAQ’s (44:56). This episode is a hard one to get excited about but once you know it well it will make your life easier. Thanks for listening!
