Protocol summary

Study aim
Determining the effectiveness of intraperitoneal washing with Tamosent solution on postoperative pain intensity in laparoscopic cholecystectomy patients
Design
A clinical trial with a control group, with parallel groups, double-blind, randomized, phase 3, 25 samples in each group, which includes 10% dropout during the study, and the number of samples for each group is 27. Allocation of samples to intervention groups is done using 6 random blocks method
Settings and conduct
Patients with symptomatic gallstones who refer to Velayat hospital and are candidates for laparoscopic cholecystectomy according to the order of the patient's surgeon. In group A, the surgeon will inject 200 ml of Tamosent solution in the space below the diaphragm and the gallbladder area under the guidance of a camera. did In group B, at the end of the operation, 500 ml of 0.9% normal saline will be used to wash the surgical bed, the upper surface of the liver and the right half of the diaphragm.

Randomized
Randomization description
This study is a double-blind randomized clinical trial that is conducted in patients with symptomatic gallstones who refer to educational-therapeutic centers in the province and are candidates for laparoscopic cholecystectomy according to the order of the surgeon. Using the method of random blocks (Balance block randomization), they are assigned to two treatment groups A and B, the balanced randomization method for the participants in the randomized controlled clinical trial study of intraperitoneal lavage with Tamosent solution (group A) and intraperitoneal lavage with normal saline alone (group B) on postoperative pain intensity in laparoscopic cholecystectomy patients.
Blinding (investigator's opinion)
Double blinded
Blinding description
Checklist information is provided by the secretary of the department in which people with national code are registered to the person responsible for the analysis and statistical analysis of the plan. After entering SPSS and coding 1 and 2, the results of the evaluation will be analyzed by the statistics professor, separated into intervention and control groups (which only the secretary of the department knows about). It is not known which washing method it received. The analyst and the data safety monitoring committee are not aware of which solution the patients received.

Intervention groups

1

Description
Intervention group: Intraperitoneal washing with Tamosent solution (group A): At the beginning of surgery and right after inflating the pneumoperitoneum and before any dissection of the gallbladder, the surgeon injects 200 ml of Tamosent solution (a mixture of 5 ampoules of 0.5% bupivacaine and one vial of 7.5% sodium bicarbonate in 450 ml of normal Saline) will be injected in the space under the diaphragm and the gallbladder area with the guidance of the camera. The patient was kept in the Trendelenburg position for 5 to 10 minutes. After that, the patients will be placed in the anti-Trendelenburg position to start the surgery, and the laparoscopic operation will be performed in a standard way, and the rest of the serum containing the Tamosent solution will be injected during the surgery and at the end of the operation.

Description
Control group: Intraperitoneal lavage with normal saline alone (group B): After placing the laparoscopic ports, the patients will be placed in the anti-Trendelenburg position to start the surgery, and the laparoscopic operation will be performed in a standard way, and at the end of the operation, 500 ml of 0.9% normal saline will be used to wash the upper surface of the liver and below the surgical bed. A semi-right aperture will be used. After the removal of the gallbladder is completed in both groups, fluids will be completely aspirated before the pneumoperitoneum is drained. At the end of the surgery, CO2 is carefully drained by manually compressing the abdomen with open trocars (especially through the epigastric trocar) and the drain will not be used.
