Background: Emergence cough during endotracheal extubation can lead to complications. This cough is triggered by the deviation of the endotracheal tube from the airway anatomy, causing pressure on the airway mucosal wall. Head elevation has the potential to align the airway passage with the tube’s configuration. In this study, we aimed to investigate the impact of head elevation using a pillow on the prevalence and severity of emergence cough in male patients. Material/Methods: A total of 71 male patients undergoing laparoscopic cholecystectomy were randomly assigned to either the head elevation group (n=35) or the control group (n=36). The head elevation group maintained a position with a neck flexion angle of 35ºusing a pillow, while the control group remained in a neutral position after anesthetic induction. The severity of cough was assessed before, during, and after extubation using a 4-point scale, with grades 2 and 3 indicating cough and grade 3 indicating severe cough. Results: The characteristics and intraoperative data of the patients were similar between the two groups. There was no significant difference in the incidence of cough and severe cough between the groups. However, the severity of cough was significantly lower in the head elevation group compared to the control group before extubation (cough scale: 0/5/8/23 vs 1/2/17/15 in the control group vs the head elevation group, P=0.039). The time to extubation, respiratory complications, nausea, pain, and the number of patients receiving fentanyl were comparable between the groups. Conclusions: Head elevation using a pillow effectively reduced the severity of cough before endotracheal extubation during anesthesia emergence in male patients. However, it did not significantly reduce the incidence of cough. These findings highlight the potential benefits of head elevation in minimizing the discomfort associated with emergence cough.
