Evaluation of emergence agitation after general anaesthesia in rhinoplasty patients: Inhalation anaesthesia versus total intravenous anaesthesia.

Emergence agitation (EA) is a clinical condition that occurs early in recovery from general anaesthesia, and reduces patient comfort. The aim of this study was to compare the effects of low-flow sevoflurane anaesthesia and total intravenous anaesthesia (TIVA) on agitation in rhinoplasty patients, and to determine the frequency of EA in low flow sevoflurane anaesthesia after rhinoplasty.A total of 90 rhinoplasty patients, under general anaesthesia were included in this prospective randomised study. After induction of anaesthesia, propofol infusion was initiated in the TIVA group (n = 45), and sevoflurane was administered in the SEVO group with a fresh gas flow of 1 l/min and MAC (minimum alveolar concentration) 1-1.1 (n = 45). Early emergence times, Richmond agitation-sedation scale (RASS), Boezaart scale, Likert scale and incidences of nausea/vomiting were recorded at the end of surgery.Early emergence time was significantly shorter in the TIVA group, than in the SEVO group (p < 0.001). İntraoperative bleeding was significantly lower in the TIVA group, than in the SEVO group (p = 0.005), and surgical field image quality and surgeon satisfaction were better in the TIVA group (p = 0.016, p < 0.001). The ratio of patients with RASS > +1 for all patients was 35.6% at 0 min, postoperatively. This rate was 12.2% (n = 11) in the TIVA group, and 23.3% (n = 21) in the SEVO group (p = 0.028).In rhinoplasty, TIVA caused shorter early emergence times, less bleeding, high surgeon satisfaction, and lower EA scores when compared with low flow sevoflurane anaesthesia.
