Incidence and Factors Affecting Shivering in Patients Undergoing Anesthesia in Phaholponpayuhasena Hospital Kanchanaburi

Abstract

The Anesthesiology Department of Phaholponpayuhasena Hospital is a department that provides anesthesia services to patients undergoing all types of surgeries. It was found that shivering was the second most important complication of anesthesia-related complications in the department. The incidence of shivering in patients after anesthesia is a problem that affects patients with cardiovascular disease, raising the risk of serious complications. This research is a prospective cohort study. The objective is to study the incidence and factors affecting shivering in patients undergoing anesthesia at Phaholponpayuhasena Hospital, Kanchanaburi by collecting data of patients who received anesthesia services Between March 1st - April 8th, 2021, 260 cases. Data were analyzed by descriptive statistics such as number, percentage, mean and standard deviation. Factors affecting shivering in patients undergoing anesthesia were analyzed using t-test and chi-square test.

Results: The incidence of shivering was 18.5% categorized as Level 2 (tremors were seen in only one muscle group), 6.2%. Level 3 (tremors were seen in more than one muscle group), 1.9%. Level 4 (tremors of the muscles throughout the body), 10.4%. No incidence of shivering was 81.5% categorized as Level 0 ( no tremors) 78.1%. Level 1 ( goosebumps) 3.5% When analyzing the data, it was found that the body mass index (kg/m²) of the patients with shivering =23.36 ± 4.20 had a significantly lower BMI than the patients without shivering = 25.36±4.57 (p=0.006). However, sex, age, body temperature before entering the operating room, operating room temperature, type of anesthesia, type of surgery, surgical period, the amount of water received, the amount of blood lost, the use of detergents inside the body, the use of hot air dryer and warming the intravenous solution had no effect on the incidence of shivering.

Based on the results of this research, guidelines should be developed to prevent the incidence of shivering in patients with a body mass index less than 25 kg/m².
