The incidence of mild hypothermia after total knee or hip arthroplasty: A study of 2600 patients

Abstract

Hypothermia is associated with a higher risk of perioperative complications and occurs frequently after total joint arthroplasty (TJA). The incidence of hypothermia following total joint arthroplasty was assessed with its risk factors and its correlation with PJI. Correlation of hypothermia with age, gender, BMI, type of arthroplasty surgery, type of anesthesia, operation time, blood loss, date of surgery and PJI was evaluated in 2600 patients. Female gender and spinal anesthesia increased the risk for hypothermia whereas an increased BMI and surgery duration correlated decreased the risk of hypothermia. The incidence of hypothermia decreased over time without a correlation with PJI.

Incidence of Unintentional Intraoperative Hypothermia in Pediatric Scoliosis Surgery and Associated Preoperative Risk Factors

“…The reported incidence of intraoperative hypothermia ranges from 2.7% to 74%. [3][4][5][6][7][8] Lai et al assessed 502 pediatric patients undergoing general surgery, including neonates and older children, and found intraoperative hypothermia in 53.2%. 3 Mehta et al report that 74% of patients undergoing major colorectal surgery experience mild perioperative hypothermia.…”

“…6 In studies of orthopedic surgery, Parodi et al assessed intraoperative hypothermia in 73 patients (mean age, 33 years) who underwent hip arthroscopy, noting that only 2.7% of the patients experience a decrease in core temperature to less than 35°C. 4 Scholten et al and Leijtens et al studied the incidence of hypothermia after total knee and total hip arthroplasty, 7,8 reporting that 11.7% to 26.7% of patients, respectively, experience mild hypothermia (< 36°C). This wide range may be explained by differences in patient population, surgical procedures, definitions of hypothermia, measuring methods, warming methods, and operating room temperatures.…”

“…1,2 Perioperative hypothermia is observed in 2.7% to 74% of all patients who underwent elective surgery. [3][4][5][6][7][8] It has been reported that hypothermia is associated with perioperative complications such as blood loss, wound infection, shivering, and mortality. 1,[9][10][11][12][13] Therefore, perioperative heat retention methods to prevent perioperative hypothermia such as providing a warmed blanket and active patients warming are important.…”

General anesthesia might be associated with early periprosthetic joint infection: an observational study of 3,909 arthroplasties

“…On the other hand, one could speculate regarding a potential negative effect of spinal anesthesia on the incidence of early PJI induced by intraoperative hypothermia, which has been associated with an increased incidence of SSIs in other surgical specialties and is more prevalent during spinal anesthesia (Scholten et al. 2018). However, despite the latter, spinal anesthesia was still associated with a reduced risk of early PJI in our study.…”

The effects of active warming on perioperative inadvertent hypothermia in patients undergoing vitreoretinal surgery under local anesthesia

“…[ 1 2 ] The incidence varies between 11% and 90% depending on the type of surgery conducted and anesthesia administered. [ 3 4 ] The risk increases in patients with an American Society of Anesthesiologists (ASA) risk score of >1, an age of ≥60 years, a low body mass index (BMI); those who receive a combination of general and regional anesthesia; and those who undergo moderate or major surgery. [ 5 6 ] PIH has also been shown to alter intraoperative drug effects, increase bleeding and delay the recovery time, increase cardiac side effects, and increase infection rates.…”
