Effect of ultrasound-guided superior laryngeal nerve block on tracheal tube-related responses during postoperative recovery in craniotomy patients: a randomized controlled trial

Key Points

This research aims to evaluate the effectiveness of ultrasound-guided superior laryngeal nerve block (SLNB) on tracheal tube-related responses during postoperative recovery in craniotomy patients.
Conducted a randomized controlled trial
Administered ultrasound-guided SLNB
Monitored extubation-related responses during anesthetic emergence
Assessed hemodynamic fluctuations and coughing
SLNB significantly reduced coughing during extubation
Attenuated hemodynamic fluctuations observed
Contributed to a smoother emergence profile post-surgery

Abstract

The SLNB significantly suppressed extubation-related responses during anesthetic emergence after craniotomy by reducing coughing and attenuating hemodynamic fluctuations, thereby contributing to a smoother emergence profile.
