Dexamethasone is a potent synthetic glucocorticoid with uses across a wide range of clinical settings due to its anti-inflammatory and immunosuppressive properties (Johnson et al., 2023). It suppresses neutrophil migration, reduces lymphocyte proliferation, decreases capillary permeability, and inhibits several pro-inflammatory cytokines.

Diagnostic testing for Cushing syndrome, while off-label clinical uses of dexamethasone include treating nausea and vomiting due to...

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.

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

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.

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

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.

Several tools and metrics have been designed to measure intraoperative nociception and analgesia In order to optimize patient outcomes...

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.

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-related behaviors is examined through neurotransmitter modulation, dopamine signaling...
