Effectiveness of Preemptive Versus Preventive Antiemetic Treatment in Patients Undergoing Laparoscopic Cholecystectomy. A Randomized Double Blind Trial.
Patients aged between 20 and 70 years, ASA physical status I-III, and scheduled for laparoscopic cholecystectomy under general anaesthesia will be enrolled in the study.
Patients will be randomized to the preemptive group to receive an antiemetic regime 1h before the start of surgery or to the intraoperative group to receive the same antiemetic drugs in the same doses intraoperatively, 30 min before the end of surgery.
In the operating room standard monitoring and a standardized anesthetic technique will be implemented in all patients. Nausea, vomiting, retching and PONV (cumulative) will be recorded at PACU, at 4h, 8h and 24h postoperatively. Pain scores assessed by NRS (numerical rating scale) will be recorded at the same time points. Also, when patients received fluids and solid food by mouth will be recorded.
