Anesthetic Considerations For Cardiac Compression And Tamponade
Over the course of my training as a cardiac anesthesiologist and intensivist, I've come across many manifestations of cardiac compression ranging from hemorrhagic pericardial effusions to massive clots. Although the general teaching is to...

Nitric Oxide
Nitric oxide is a molecule normally made by vascular endothelial cells to decrease vascular resistance in both the systemic and pulmonary circulations. Inhaled nitric oxide (iNO) is an (expensive) pulmonary dilator I frequently use...

Do You Titrate Vasopressin?
Compared to catecholamine infusions which are routinely titrated, there's a polarized practice with vasopressin - those who titrate and those who don't. As a resident, I worked with intensivists who strongly believed in "0.04...

Positive End Expiratory Pressure (PEEP) and Cardiac Output
One of the cardiopulmonary challenges I constantly face as a cardiothoracic anesthesiologist and intensivist is balancing positive end-expiratory pressure (PEEP) with cardiac output (CO). CO is related to the heart rate (HR) and stroke...

High Dose Fentanyl Induction
The induction of general anesthesia in patients undergoing cardiac surgery is often times different than non-cardiac surgery. At many institutions, these inductions tend to center heavily around high dose opioids due to the hemodynamic...

Phentolamine
Phentolamine (Regitine) is a reversible α-1 and α-2 blocker used primarily for its vasodilatory effects. When used to control hypertension, one must consider the autonomic effects of blocking these receptors.
Profound vasodilation will lead to...
