SECONDARY outcome

Timeframe: up to 72 hours after surgery

Population: Postoperative pain measurements were not available for 19 isoflurane patients and 20 sevoflurane patients.

Time-weighted average VRS (Verbal Rating Scale) pain score over the first 72 h after surgery as recorded by nurses at approximately 4-h intervals. The VRS pain score is from 0 (no pain) to 10 (worst imaginable pain).
