The results of this study suggest that preoperative warming can reduce rates of SSI after surgery .
OBJECTIVE To determine whether preoperative warming can reduce the risk of surgical site infection ( SSI ) after surgery .
BACKGROUND Intraoperative hypothermia is a risk factor for the occurrence of  SSI in patients after surgery .
However , the effectiveness of preoperative warming in reducing the incidence of the condition remains unclear .
The effects of a forced-air warming system plus electric blanket for elderly patients undergoing transurethral resection of the prostate
Background : Perioperative inadvertent hypothermia in elderly urology patients undergoing transurethral resection of the prostate ( TURP ) is a well-known serious complication , as it increases the risk of myocardial ischemia , blood loss , and surgical wound infection . We conducted this prospect i ve r and omized controlled trial to evaluate the combined effect of a forced-air warming system and electric blanket in elderly TURP patients . Methods : Between January 2015 and October 2017 , we recruited 443 elderly male patients undergoing elective TURP with subarachnoid blockade ( SAB ) . These were r and omly divided into 3 groups : group E ( intraoperative warming using electric blankets set to 38 ° C ; n = 128 ) ; group F ( intraoperative warming using a forced-air warmer set to 38 ° C ; n = 155 ) and group FE ( intraoperative warming using a forced-air warmer plus electric blankets , both set to 38 ° C ; n = 160 ) . The primary outcome was shivering and their grade s. Hemodynamic changes , esophageal temperature , recovery time , incidences of adverse effects , and patient and surgeon satisfaction were also recorded . Results : Baseline characteristics showed no significant differences when compared across the 3 groups ( P > .05 ) . Compared with groups E and F , both HR and mean arterial pressure ( MAP ) in group FE were significantly decreased from T6 to T10 ( P < .05 ) . Compared with groups E and F , esophageal temperature in group FE increased significantly from T5 to T10 ( P < .05 ) . Compared with group E , esophageal temperature in group F was significantly increased from T5 to T10 ( P < .05 ) . Compared with groups F and FE , post-anesthesia care unit ( PACU ) recovery time was longer in group E , while compared with group F , PACU recovery time was shorter in group FE ( P < .05 ) . Compared to patients in groups E and F , those in group FE had a significantly lower incidence of arrhythmia and shivering ( P < .05 ) . The number of patients with shivering grade s 0 to 3 was higher in group E than in other groups , while the number of patients with shivering grade 2 was significantly higher in group F than in group FE ( P < .05 ) . Patient and surgeon satisfaction scores were higher in group FE than in groups E and F ( P < .05 ) . Conclusions : Use of a forced-air warming system combined with an electric blanket was an effective method with which to retain warmth among elderly TURP patients
