Analgesic evaluation
sleepiness, nausea, vomiting, pruritus, pain
GASTROINTESTINAL BLEEDING, RESPIRATORY DEPRESSION, COMPLICATIONS, CARDIAC ARRHYTHMIA
Visual Analogue Scale/Score (VAS) is used for analgesic evaluation. VAS is divided into a linear graph with a 10 cm × 3 cm linear scale, where “0” on the left side indicates no pain and “10” on the right side indicates the most severe pain imaginable. The pain scores of the four groups were compared at 2, 12 and 24 h after surgery. The time of surgery, time of awakening and time of extubation were recorded for the four groups. The patients were observed for complications such as respiratory depression, cardiac arrhythmia, and gastrointestinal bleeding. The use of other analgesics on demand, and the occurrence of nausea, vomiting, sleepiness and pruritus were recorded in the 24 h postoperative period.
