Malignant hyperthermia is a rare but rapidly progressive anesthetic emergency in which abnormal skeletal muscle calcium regulation drives a hypermetabolic crisis. In Part 3 of the Perioperative Crisis Management series...

Amniotic fluid embolism is a rare but catastrophic obstetric emergency that can produce abrupt hypoxemia, severe pulmonary hypertension, acute right-ventricular failure, cardiovascular collapse, and disseminated...

When a patient suddenly deteriorates in the operating room, the first few minutes are not about naming the diagnosis—they are about recognizing the physiologic pattern, protecting oxygen delivery, and treating...

In Part 3 of the Elderly Physiology series, we break down how aging changes renal function, hepatic function, body composition, and ultimately the way anesthetic drugs behave in older adults. We’ll review age-related...

Aging changes nearly every organ system—and those physiologic changes can dramatically affect how an older adult responds to anesthesia, surgery, and perioperative stress. In Part 1 of the Elderly Physiology series, we...

In Part 7 of the Local Anesthetics series, we’re breaking down epidural anesthesia from placement to troubleshooting . We’ll cover how to confirm epidural catheter placement, the purpose and interpretation of the...

In Part 6 of the Vital Flow Local Anesthetics series, we’re going beyond the local anesthetic and breaking down the drugs that can be added to spinal anesthesia to modify block quality, duration, and analgesia. We’ll...

Spinal anesthesia is more than putting local anesthetic into the intrathecal space—the drug you choose, its baricity, the patient’s position, and the dose all influence where that block goes and how it behaves. In Part...

In Part 3 of the Vital Flow Local Anesthetics series , we move from the pharmacology to the drugs themselves. This episode breaks down the two major classes of local anesthetics— amides and esters —and walks through the...

Why do some local anesthetics kick in faster, last longer, or produce a denser block than others? In Part 2 of our Local Anesthetics series, we break down the pharmacology that explains how local anesthetics actually...

In Part 1 of the Vital Flow Local Anesthetics series , we’re going back to the physiology that makes local anesthesia possible. We’ll break down how nerves generate and propagate action potentials, the role of sodium...
