Authors: Kumar H, Manoj P S, Ahmad Z, et al. Cureus 18(7): e113049. doi:10.7759/cureus.113049 Abstract Background: Superior laryngeal nerve block is one option for airway topicalization during awake fiberoptic intubation. The optimal balance between injectate volume and lignocaine (lidocaine) concentration remains uncertain. Objective: To compare a larger-volume, lower-concentration regimen (4 mL of 1% lignocaine per […]

Cureus 18(7): e112899. doi:10.7759/cureus.112899 Abstract Critical distal tracheal stenosis caused by a massive goiter poses a major airway challenge in which tracheal intubation and positive-pressure ventilation may fail, potentially leading to severe hypoxia during induction. We report the case of an 88-year-old woman with dementia who […]

Cureus 18(7): e112936. doi:10.7759/cureus.112936 Abstract Negative pressure pulmonary edema (NPPE) is a rare, life-threatening, yet rapidly reversible complication of acute upper airway obstruction. We present the case of a 17-year-old healthy male who underwent an emergency appendectomy under general anesthesia. Immediately following extubation, he developed severe […]

Patients increasingly request personalized music during transport to the operating room and prior to […]

Although historically rooted in pressure-volume analysis, time-varying ventricular elastance, and Windkessel-based arterial modeling, the concept […]
