N/A postanesthesia shivering. Intervention 1: In the experimental group involving electric blankets after surgery, Beurer HD90 blankets (made in Germany) will be used. The blankets come in 130cmx180cm dimensions and could be adjusted for six different temperatures. They feature automatic shutdown system, overheating protection and performance display light. Additionally, these blankets are certified by European Oeko-Tex which approves the textile safety for the consumers. In this group, the blanket will be used after surgery such that it will be prepared and switched on fifteen minutes prior to admission of the patient into the post anesthetic care unit. Upon arrival of the patients into the recovery unit, the blankets will be laid over them and left until the patients are discharged from the recovery unit. Intervention 2: In the second experimental group in which warm intravenous fluid is used during surgery, the required liquid intake of the patient will be determined. Once the patient is transferred on to the operating table, the required liquid will be heated to 37 °C under supervision of an anesthesiologist using Biggler Warmer – BW585 assembled in Iran. To connect the intravenous fluid to the warmer set an extension tube is used having the same length for all patients. Intervention 3: In the control group, patients will receive routine care. In the studied hospital, patients receive intravenous fluid in ambient temperature during surgery and upon completion of the operation, a usual blanket is laid over patients before transferring them into the recovery room.
