Gastrointestinal (GI) surgery, whether performed to remove a cancer, repair a hernia, or address an acute abdominal emergency, remains one of the more complication-prone areas of modern medicine due to the GI system’s inherent challenges.

Challenges of GI surgery - Wisconsin Anesthesia Another pattern from research on the challenges of GI surgery is the significant influence of patient-related, "premorbid" factors on...

Over the past decade, ambulatory surgery has become a predominant mode of surgery across many specialties.

Over the past two decades, femoral nerve block has been central to postoperative analgesia for total knee arthroplasty (TKA), but preference has shifted to other peripheral nerve blocks that can provide analgesia around the knee without the key drawback associated with the femoral block.

Use of Femoral Nerve Block Over Time - Wisconsin Anesthesia Over the past two decades, femoral nerve block has been central to postoperative analgesia for total knee arthroplasty (TKA), but preference has...

Sevoflurane is widely used because its low blood–gas solubility permits relatively rapid uptake, titration, and emergence compared with older volatile anaesthetics.

Individual Variability in Sevoflurane Sensitivity - Wisconsin Anesthesia These studies illustrate some of the factors that drive individual variability in sevoflurane sensitivity. Age-adjusted MAC provides an essential...

Traditionally, the management of perioperative analgesia has depended on hemodynamic parameters such as heart rate and blood pressure to assess whether the patient is receiving adequate analgesia.

Tools to Measure Intraoperative Nociception and Analgesia - Wisconsin Anesthesia Several tools and metrics have been designed to measure intraoperative nociception and analgesia In order to optimize patient outcomes...

Hypotension during anesthesia induction is a common and significant phenomenon that reflects the complex interplay between anesthetic agents, autonomic regulation, intravascular volume status, and underlying patient physiology.

Physiological Mechanism of Hypotension During Anesthesia Induction - Wisconsin Anesthesia Hypotension during anesthesia induction is a common and significant phenomenon that reflects the complex interplay...

Tracheostomy is a well-established airway management procedure that is frequently associated with emergency or critical care settings. However, a substantial proportion of tracheostomies are performed in non-emergent contexts.

Use of Tracheostomy in Non-Emergent Cases - Wisconsin Anesthesia Understanding the potential risks of tracheostomy in non-emergent cases is essential for clinicians involved in surgical, anesthetic, pulmonary, and...

Volatile anesthetics have been shown to modulate neurotransmitter release across multiple brain regions. For example, halothane attenuates haloperidol-induced dopamine release, while isoflurane increases γ-aminobutyric acid (GABA) but decreases glutamate release.

The Effect of Isoflurane Anesthesia on Addiction The effect of isoflurane anesthesia on addiction-related behaviors is examined through neurotransmitter modulation, dopamine signaling...
