The Effect of Hyoscine-n-butylbromide on Nausea and Pain in Laparoscopic Cholecystectomy

Phase 4

Completed

• Conditions: Cholecystitis; Pain; Nausea
• Interventions: Drug: hyoscine-n-butylbromide, ondansetron; Drug: • hyoscine-n-butylbromide • ondansetron

• Registration Number: NCT06927817
• Lead Sponsor: Saglik Bilimleri Universitesi

Brief Summary

The goal of this randomized double blind study is to compare the effects of hyoscine-n-butylbromide, and ondansetron on postoperative nausea-vomiting, and pain in patients who underwent laparoscopic cholecystectomy.The main questions it aims to answer are:

1. Is antiemetic properties of hyoscine-n-butylbromide effective after laparoscopic cholecyctectomy?

1. Does hyoscine-n-butylbromide have valuable effects on postoperative pain after laparoscopic cholecyctectomy?

Participants will be the paients undergoing laparoscopic cholecyctectomy.

The patients participating in the study were randomized into two groups as Group-HBB, and Group-O.

After the gallbladder removed, IV infusion of 1000 mg paracetamol, and 1.5 mg/kg tramadol will administered to the patients. 20 mg hyoscine-n-butylbromide in 100 ml saline will administered to the patients in Group-HBB, and 4 mg ondansetron infusion in 100 ml saline will be administered to the patients in Group-O.

Postoperative nausea and vomitting score and pain intensity and rescue drugs will be recorded in postoperative 24 hours.

Detailed Description

After obtaining the informed consent form from the patients, a total of 134 patients undergoingt laparoscopic cholecystectomy surgery will be inclueded in the study. The patients participating in the study will be randomized into two groups as Group-HBB, and Group-O by the closed envelope method. The patients will be blinded to groups they belonged to. Routine peripheral oxygen saturation, noninvasive blood pressure, electrocardiography, and bispectral index (BIS) monitoring will be performed.. BIS-guided 2-2.5mg/kg propofol, and 2mcg/kg fentanyl intravenously, and 0.6mg/kg rocuronium injection will be administered. In order to maintain the BIS value between 40-60, 1-2% sevoflurane inhalation in 40/60% oxygen/air mixture in 2-liter flow, and 0.1-0.5mc/kg/min remifentanil infusion will be applied. After the gallbladder removed, IV infusion of 1000 mg paracetamol, and 1.5 mg/kg tramadol will administered to the patients. 20 mg hyoscine-n-butylbromide in 100 ml saline will administered to the patients in Group-HBB, and 4 mg ondansetron infusion in 100 ml saline will be administered to the patients in Group-O. After the surgery terminates, 2 mg/kg sugammadex will be used to antagonize the muscle relaxant effect, and patients with adequate respiratory effort, and a BIS value above 85 will be extubated.

Demographic data of the patients such as age, body mass index, gender, comorbidities, ASA score, and smoking status will be recorded. Nausea, vomiting, and pain status will be examined in the recovery unit at postoperative 15th, and 30th minutes and in the ward at the 3rd, 6th, 12th and 24th hours. Follow-ups will be performed by an anesthesiologist who is blind to groups of the patients. A 4-point scale will be used for nausea-vomiting (0: no nausea and vomiting, 1: nausea, no vomiting, 2: nausea, vomiting, 3: vomiting more than twice), and a 10 cm VAS score will be used for assessig the pain level. Patients with a pain level of 4 and above will be administered 20 mg of tenoxicam intravenously as an analgesic. If the nausea score is \>0, 10 mg metoclopramide iv will be administered, and if the score was still \>0 after 30 minutes, 4 mg dexamethasone iv will be administered.
