There was much attention focused on the perioperative physiological states, and during the state, the hypothermia could significantly affect postoperative clinical outcomes. With the development of shoulder arthroscopy, the related perioperative physiological conditions are also continuously recognized. Still, few reports are on the influencing factors and clinical functions of perioperative hypothermia during shoulder arthroscopy. Objective Investigation of the perioperative hypothermia and factors that influence hypothermia in shoulder arthroscopy.

A total of 161 patients with shoulder arthroscopy treatment were retrospectively analyzed. The patient’s general information, operative time, ASA, anesthesia method, heat preservation measure and operating room temperature, etc., were recorded. These data and the incidence of hypothermia during the perioperative period and the risk factors were statistically analyzed.

According to the data analysis results of 155 cases of shoulder arthroscopy, the incidence of hypothermia was 27.74% after general anesthesia, and the incidence of hypothermia postoperatively was 40%. The hypothermia showed a significant correlation with gender and BMI after anesthesia. The occurrence of hypothermia during and at the end of the operation is closely related to age, gender, operation time, irrigation fluid volume, and heat preservation measure. When the operation time exceeds 90 minutes, the irrigation fluid temperature has an essential role in changing the core temperature.

Various factors in shoulder arthroscopy are associated with perioperative hypothermia. The temperature of the irrigation fluid also has a particular effect on the core temperature, leading to the occurrence of hypothermia during the perioperative period.
