In this episode I welcome back Dr. David Mintz, neuroanesthesiologist, to discuss the treatment of increased intracranial pressure in the perioperative period and brain relaxation during neurosurgery. Dr. Mintz will be back in the future to talk about the physiology of increased ICP.
In this episode I discuss the use of IV fluids for perioperative use including how to decide when to give fluid, the downsides of over resuscitation, whether to use crystalloid or colloid, and whether to use saline or a balanced salt solution such as LR.

This is the second of two episodes about opioid medications. In this episode I cover the pharmacokinetics and pharmacodynamics of opioids, some of the common uses for these medications, mixed agonist-antagonist compounds, opioid antagonists, and opioid interaction with other medications.

This is the first of a 2 part series on opioid medications. In this first episode I will talk about how opioids are categorized and their effects on the different body systems. In the next episode I will discuss their pharmacokinetics and pharmacodynamics as well as their various uses and some details on mixed agonist/antagonists.

PLEASE NOTE: Around minute 12 I say that auditory evoked potentials are the most sensitive to anesthetics. This is incorrect. I should have said visual evoked potentials. Thanks to Howard Zee for catching that!
In this episode I welcome Dr. David Mintz, one of our neuroanesthesiologists here at Johns Hopkins, fellow Brown University Alum, and generally all around great guy, to the show to talk about air embolism, what it is, how it happens and how to manage it. A big thanks to Dave for taking the time to prepare this information and for being the first ever guest on ACCRAC.

In this episode I discuss hyperoxia and review the evidence in regards to the damage it can cause in patients with a wide variety of illnesses.
Slides to accompany the episode can be found here: hyperoxia slides
In this episode I review the common IV agents used in anesthesia excluding opioids. I cover Propofol, Barbiturates, Benzodiazepines, Ketamine, Etomidate and Dexmedetomidine.
NOTE: There is an error in the audio recording regarding the dosing units for dexmedetomidine. I say on the podcast that the dosing units are mcg/kg/min which is INCORRECT. The correct dosing units are mcg/kg/HOUR. I have corrected this in the accompanying slides. Thanks to Melanie Browder for picking this up!
Good luck to the recent graduates taking their written board exam on July 29th!

In this episode I review the basic medication setup for the operating room including premedication, induction, neuromuscular blockade, antibiotics, reversal and antiemetics. I discuss weight based dosing and comment on a few alternatives to consider once you have the basic setup down. This episode should be useful for new CA-1s getting started in the OR but I would also like to ask senior residents to comment on what their basic setup is and how it may differ from what I’ve mentioned here.
Here is a list of the medications I discuss: Basic med setup w dosing
This is the second and final episode dealing with the management of respiratory diseases. In the first episode I covered the initial evaluation and preop preparation. In this episode I cover intraoperative management, post-operative management, special issues related to one lung ventilation and special issues related to total pneumonectomy.

This is the first of a two part series of episodes on the management of patients with respiratory disease. In this, part 1, I cover the preoperative evaluation, history and physical exam, and the preoperative planning and optimization of the patient. This includes the key board topics of smoking cessation and cardiac risk assessment.
