Clinical Impact of Active Inflatable Insulation in Older with Undergoing Knee Arthroplasty.

ABSTRACT

Objective: This study aimed to explore the safety and effectiveness of active inflatable insulation in older patients who underwent knee arthroplasty. Methods: A total of 210 patients who came to our hospital for knee arthroplasty between November 2020 and December 2021 were selected for the study. They were randomly divided into a control group and two experimental groups, i.e., the intraoperative active warming (IOAW) group and the perioperative active warming (POAW) group, with 70 patients in each group. IOAW measures are taken to reduce heat loss during surgery and help maintain core temperature. POAW measures were taken to reduce the heat loss during surgery and help maintain the core temperature. The core body temperature, incidence of hypothermia, chills, bleeding volume (P = .043), extubation and awakening time, blood routine, and coagulation function of the patients in the three groups were compared. Results: The core body temperature in the POAW group was higher than that in the IOAW and control groups. The awakening and extubation times in the POAW group were shorter than those in the IOAW and control groups. The incidences of hypothermia, chills and intraoperative bleeding in the POAW group were lower than those in the IOAW and control groups. Conclusion: Perioperative active inflatable insulation for older patients undergoing knee arthroplasty can effectively protect the core body temperature, reduce the incidence of perioperative hypothermia, and reduce related complications. This measure is beneficial for the postoperative recovery of patients and provides a reference for active inflatable insulation measures for clinical knee arthroplasty.
