充气升温毯干预对麻醉复苏室患者低体温相关并发症的预防效果

Abstract: Objective To observe the preventive effect of inflatable warming blanket intervention on hypothermia related complications in patients in the post-anesthesia care unit (PACU), and provide scientific basis for optimizing PACU nursing plan in clinical practice. Methods A total of 80 PACU patients from June 2024 to June 2025 in our hospital were selected and grouped by random number table method. The control group (n=40) used regular cotton blankets to cover the patients’ bodies, while the intervention group (n=40) combined the regular cotton blanket with an inflatable warming blanket. The temperature changes of both groups of patients were compared at different time points: upon entering the PACU (T0), 15 minutes after entering the PACU (T1), 45 minutes after entering the PACU (T2), and upon leaving the PACU (T3). Vital signs (systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), complication rates and recovery indicators at different time points were also compared. Results At T1, T2, and T3, the intervention group had higher body temperature than the control group (P＜0.05). At T1, T2, and T3, the intervention group had higher SBP and DBP than the control group, and lower HR than the control group (P＜0.05). The incidence of complications in the intervention group was lower than that in the control group (P＜0.05). The PACU stay time and total hospitalization time in the intervention group were shorter than those in the control group (P＜0.05). Conclusion Inflatable warming blanket intervention can effectively maintain stable body temperature in PACU patients, improve vital signs, reduce the incidence of complications such as hypothermia, shivering, and arrhythmia, shorten PACU stay time and total hospitalization time, and has good safety. It is worth promoting and applying in clinical PACU treatment.
