Comparison of the Effects of Warm CO2 Insufflation and Local Heat on Hemodynamic Changes, Temperature, Chills, and Shoulder Pain After Surgery in Patients Undergoing Laparoscopic Cholecystectomy

Comparison of the effect of warm CO2 gas blowing with local heat and the control group on hemodynamic changes, temperature, shivering and shoulder pain after surgery in patients who are candidates for laparoscopic cholecystectomy surgery in Shohada Mehrab H, Yazd in 1403

The clinical trial with a control group, a blind, randomized, on 93 patients, was used for randomization

According to the number on the envelope, the researcher determines the type of intervention and takes action. Before the surgery (demographic information, temperature and hemodynamic parameters of the patient) will be recorded in all groups. group A: warm carbon dioxide gas to cause pneumoperitoneum in patients. group B: use from CO2 gas at room temperature and two warm water bags on the common site of pain (in the shoulder area) group C: used CO2 gas is at room temperature. During surgery, the patient's temperature and hemodynamic parameters, the surgeon's satisfaction level in terms of surgical field bleeding will be recorded. After the end of shivering surgery, hemodynamic parameters, temperature, pain are recorded. Sampling location of Shahada Mehrab Hospital, Yazd; The study is a blind study and patients receive the type of intervention on the envelope after anesthesia, and the patient does not know the type of intervention

Inclusion criteria: Age range from 18 to 60 years; ASA Ⅰ & Ⅱ; BMI (5/18-9/24) ; Informed consent Exclusion criteria: Converting laparoscopic surgery to an open surgery; adhesions; the duration of the surgery is more than one hour; the history of alcohol and smoking

A: using Warm carbon dioxide gas, B: using local heat in the common place of shoulder pain. C: use of carbon dioxide gas at normal temperature

shoulder pain; Temperatures; hemodynamic parameters; Shivering

Before starting the study, eligible patients are assigned to three groups using block randomization. Then, six blocks are set with three letters (A: hot gas intervention group, B: local heat intervention group, and C: control group). With 27 possible blocks (from number 1 to 27), 15 blocks of six in each group are selected randomly until the sample size is completed, and by determining the Master sheet and matte envelopes, the list of continuous admission of patients from number 1 to 93 is on the envelope. And the type of intervention is specified inside the envelope. The main list remains with the senior researcher. The researcher was present in the operating room on the day of the operation and after examining the patients, if the patients are eligible, the envelope is opened according to the number on the envelope that is in the possession of one of the operators, and the type of intervention is specified and action taken

one blinded - Patients - After obtaining a written consent from the patient, The patient will be anesthetized, and then the Intended intervention will be applied (at the same time as the surgery, a warm water bag is placed in the common place of shoulder pain, or warm CO2 gas is injected into the abdomen after the surgical incision, or no intervention is performed). At the end of the surgery and before Consciousness of the patient, the intervention will end and the patient will not be conscious of the type of intervention.
