Comparison of the effect of standard pressure versus low pressure pneumoperitoneum with surgery site suction on the severity of shoulder pain in patients undergoing laparoscopic cholecystectomy

Determining the effect of comparing standard pressure with low pressure pneumoperitoneum with surgery site suction on the severity of shoulder pain in patients undergoing laparoscopic cholecystectomy

A clinical trial with a control group, with a parallel group, one-sided blind and patients unaware of the group assigned to them, randomized, coin toss was used on 70 patients who were candidates for laparoscopic cholecystectomy.

The research site will be the operating room and surgery wards of Motahhari and Peymaniyeh hospitals in Jahrom. The researcher selects patients according to the list of patients ready for cholecystectomy surgery and after explaining the reason for the research and obtaining consent and if there are criteria. Admission completes a questionnaire for patients. The researcher assures patients that their name will be kept confidential, they will be free to leave the study at any time if they wish to leave the study. Patients are measured at specific times by attending their bedside.

Patients aged 18 to 70 years who are candidates for laparoscopic cholecystectomy surgery - having ASA1,2 - elective laparoscopic cholecystectomy - informed consent to participate in the study

Intervention group 1: Standard pressure group of pneumoperitoneum with carbon dioxide pressure of 12 to 15 mm Hg Intervention group 2: Low pressure group of pneumoperitoneum with carbon dioxide pressure of 8 to 11 mm Hg with suction area

Severe postoperative shoulder and abdominal pain, preoperative anxiety, rate of postoperative analgesia

For randomization, a simple randomization method is used. Using coin tossing, the intervention group is determined, so that if the side is lined, patients are in the intervention group, and if the side is not lined, patients are in the group. Will be controlled. The unit is individual randomization. The method of hiding random allocation in this study is the SNOSE method. In this method, first a random sequence is performed, then based on the sample size of the research, a number of envelopes with aluminum wrappers are prepared and each of the random sequences created is registered on a card and the cards are placed inside the envelope. In order to maintain a random sequence, envelopes are numbered in the same way on the outer surface of the envelopes. Finally, the lids of the letter envelopes are glued and placed inside a box, respectively. At the beginning of the registration of participants, based on the order of entry of eligible participants to study, one of the envelopes of the letter is opened and the assigned group of the participant is revealed. In the implementation phase of the random allocation process of this study, cases such as the individual who created the random sequence, the person who examined the participants in terms of inclusion and exit criteria, and the participants who studied and participated in the study. It is intended that three separate individuals perform the randomization process without being aware of the actions of other researchers.

Patients are told about standard pneumoprotein pressure and low pneumoperitoneum pressure, but are not aware of which group they belong to.
