Abstract
The analysis included data from 1300 patients; mean patient age was 44 years. Opioids and isoflurane were the most frequently used drugs (opioids in 1095 [84%] patients and isoflurane in 971 [75%] patients).
Neuro-muscular blocking drugs (NMBD) were used in 770 (59%) patients. Tracheal intubation was used in 65% procedures and laryngeal mask airway in 29% procedures.
The mean induction time was 9 minutes (CI 95% 8.7-9.7, range 1-100), the mean procedure duration 91 minutes (CI 95% 87-94, range 3-690); the mean recovery time was 3 minutes (CI 95% 2.9-3.2, range 0-35). Patients given NMBD showed a statistically significant increase in recovery time (3.5 min, CI 95% 3.3-3.7 vs. 2.4 min, CI 95% 2.2-2.6; p < 0.001).
Procedure duration correlated with recovery time (correlation coefficient = 0.114; p < 0.001).
