Details and patient eligibility

About

Irrigation fluids used during hip arthroscopy surgery are generally stored at room temperature and are cooler than the core temperature of the patient. They are used abundantly during hip arthroscopy surgery. The aim of this study is to detect local and then general hypothermia that may occur by monitoring the body temperature from the rectal mucosa of patients undergoing hip arthroscopy, using irrigation fluids of different temperatures and comparing it with the temperature measured from the temporal region.

Full description

This is a prospective randomized controlled study where sequential randomization will be applied to patients; The first patient will be included in the 1st group, and the second patient will be included into the 2nd group, and so on. All patients scheduled for hip arthroscopy in our institution during the defined study period are eligible for inclusion. While room temperature irrigation fluids will be used routinely for Group 1, irrigation fluids heated up to 36-38 degrees will be used for the other group. Patients will be operated in the same operating room and at the same room temperature with the same type/amount of covering and body warming. At the start of the surgical procedure, a probe inserted into the rectal mucosa will measure the patient's body temperature every 15 minutes. In addition, the temperature of the patients will be measured from their temporal regions with a contactless thermometer, whose batteries will be changed every two operations. The data obtained will be analyzed by a blinded researcher. Mean body temperatures measured from 2 different locations (temporal region and rectal mucosa) between the groups will be compared, and the probability of detecting early local and later general hypothermia from the rectal mucosa will be examined.

116 participants in 2 patient groups

Room Group

Active Comparator group

Description:

Room temperature irrigation fluids will be used routinely for Group 1. Patients will be operated in the same operating room and at the same room temperature with the same type/amount of covering and body warming. At the start of the surgical procedure, a probe inserted into the rectal mucosa will measure the patient's body temperature every 15 minutes. In addition, the temperature of the patients will be measured from their temporal regions with a contactless thermometer, whose batteries will be changed every two operations.

Treatment:

Procedure: Rectal temperature measurement

Procedure: Temporal temperature measurement

Warmed Group

Active Comparator group

Description:

Irrigation fluids heated up to 36-38 degrees will be used for Group 2.Patients will be operated in the same operating room and at the same room temperature with the same type/amount of covering and body warming. At the start of the surgical procedure, a probe inserted into the rectal mucosa will measure the patient's body temperature every 15 minutes. In addition, the temperature of the patients will be measured from their temporal regions with a contactless thermometer, whose batteries will be changed every two operations.
