In the fixed effect model , the warming group had significantly less pain and lower incidence of wound infection , compared with the no-warming group .
In the r and om effect model , the warming group was also associated with lower risk of post-anesthetic shivering .
Both in the r and om and the fixed effect models , the warming group was associated with significantly less blood loss .
Perioperative warming of surgical patients is effective in reducing postoperative wound pain , wound infection and shivering .
Systemic warming of the surgical patient is also associated with less perioperative blood loss through preventing hypothermia-induced coagulopathy .
OBJECTIVE The objective of this review was to systematic ally analyze the trials on the effectiveness of perioperative warming in surgical patients .
Forced-air warming and fluid warming minimize core hypothermia during abdominal surgery.
OBJECTIVE To evaluate the effect of intraoperative combined forced-air warming and fluid warming system on  patient 's core temperature , blood loss , transfusion dem and , extubation time , and incidence of postoperative shivering . METHODS Forty patients with American Society of Anesthesiologists physical status I and II , aged 18 - 70 years , scheduled for elective abdominal surgery were r and omly assigned to receive intraoperative warming from a forced-air blanket and fluid warming system or conventional cotton blanket , 20 in each group . The core temperature was recorded every 20 minutes during the operation , as well as the blood loss , blood transfusion , extubation time , and incidence of postoperative shivering . RESULTS The core temperature at the end of the surgery in the warming group was significantly different from that in the control group ( 36.4 + /- 0.4 degrees C vs. 35.3 + /- 0.5 degrees C , P < 0.001 ) . Application of intraoperative warming significantly shortened the time between the end of the surgery and extubation ( P < 0.01 ) . Postoperative shivering occurred in 30 % of the patients in the control group compared to no patient in the warming group ( P < 0.01 ) . CONCLUSION Active warming with air-forced blanket and fluid warming system provides sufficient heat to prevent hypothermia during abdominal surgery
