Hypothermia in surgery can increase surgical blood loss in patients

reports that patients with surgery who develop ediles of mild hypothermia (lower than normal body temperature ( 1 degree Celsius) during surgery significantly increase the relative risk of blood loss during surgery (about 16 percent) and blood transfusions (about 22 percent)(Anesthesiology 2008,108 (1: 71)hypothermia caused bysurgical anesthesia can reduce the patient's platelet function and damage the clotting enzyme involved in the coagulation cascade, while hypothermia in surgery can increase the risk of heart failure, adverse heart muscle events and infection, and can prolong the patient's recovery time after surgeryHowever, the conclusion of the relationship between hypothermia and surgical blood loss in surgery was inconsistentRajagopalan et al., conducted a meta-analysis, comprehensively searched the relevantliterature from 1966 to 2006, and included published randomized studies of blood loss and/or blood transfusion in patients with mild hypothermia (34 to 36 degrees C) surgeryAssess whether mild hypothermia during surgery increases surgical blood loss and the need for blood transfusionsThe results showed that 14 studies analyzed the relationship between hypothermia and blood loss, and 10 studies analyzed the relationship between hypothermia and blood transfusionThe median temperature difference in patients with normal and mild hypothermia was 0.85 degrees CThe ratio of normal body temperature to the geometric average of total blood loss in patients with mild hypothermia was 0.84 (0.74 to 0.96, P-0.009)The normal body temperature is lower and the patient's blood transfusion needs are reduced, with a total estimated relative risk of 0.78 (P-0.027)The researchers believe that maintaining a normal body temperature during surgery can reduce the amount of blood loss and the need for blood transfusion, which should be of clinical attention
