The Effect of Inadvertent Perioperative Hypothermia on Surgical Site Infection in Laparoscopic Choleistectomy.

Study Overview
=================
Brief Summary
-----------------
There are conflicting results in the literature explaining the relationship between surgical site infection (SSI) and inadvertent perioperative hypothermia (IPH). Although it is thought that the risk of IPH is lower in laparoscopic surgery types due to the short duration of the surgical procedure, these conflicting results raise doubts as to whether there is a relationship between IPH and SSI in laparoscopic surgery patients. A randomized controlled study will be planned in the future to examine the effect of IPH on SSI in patients who will undergo laparoscopic cholecystectomies. The study will be conducted in the general surgery clinic and operating room of a university hospital. It will be completed with a total of 100 patients, 50 of whom will be in the case group, and 50 will be in the control group.

Detailed Description
-----------------
Objective: This study was conducted to examine the effect of inadvertent perioperative hypothermia (IPH) on Surgical Site Infection (SSI) in patients undergoing laparoscopic cholecystectomy. Summary of Background Data: There are conflicting results in the literature explaining the relationship between SSI and IPH. Although the risk of IPH is thought to be lower in laparoscopic surgery types due to the short duration of the surgical procedure, these conflicting results raise doubts about the existence of a relationship between IPH and SSI in laparoscopic surgery patients. Methods: This study will be a quasi-experimental and randomized controlled study in the future. The study will be conducted with patients who will have undergone laparoscopic cholecystectomy in the general surgery clinic and operating room of a university hospital. The study will be completed with a total of 100 patients, 50 in the case group, and 50 in the control group. During the study, preoperative, intraoperative, and postoperative body temperatures, as well as biomarkers of the patients, will be monitored using a form developed by the researchers. Additionally, patients will be followed up postoperatively to evaluate the potential impact of IPH on SSI.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental group<br>The population of the study consisted of patients who were being treated in the general surgery clinic of the hospital, who met the sampling criteria, who were to undergo laparoscopic cholecystectomy, and who agreed to participate in the study. The sample size of the study was determined by the G*Power 3.1.9.7 program. In the power analysis, when α =0.05, β=0.10, and 1-β =0.90, the sample size was determined as 50 people per group and a total of 100 people. | Other: Prevention hypothermia<br>* Hypothermia was prevented by warming the case group. control group remained stable. As a result, the presence of surgical site infection was followed.<br>|
