Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Preoperative, intraoperative and postoperative hypothermia is the drop of body temperature below 36 ° C within one hour before surgery and within 24 hours postoperatively. It is the most common but preventable thermal disorder during anesthesia. It occurs as a result of anesthesia on thermoregulation during surgery and exposure to cold operating room. Although it can be seen in all anesthetized individuals before, during and after surgery due to age, sex, body surface area and body shape; duration, depth, signs and symptoms may vary.
The American Society of Operating Room Nurses (AORN) emphasized the importance of the use of appropriate heating devices in the prevention of hypothermia in surgical patients. Experimental studies and meta-analyzes indicate that active methods of preventing hypothermia (hot air blown systems, hot water circulating blankets and garments, liquid heaters, blood and blood product heaters, etc.), passive methods (wool and synthetic woolen materials, garments and blankets, insulation) materials, etc.) are more effective. It is recommended to use more than one method together to maintain normothermia before, during and after surgery.
Hypothermia is an important problem that should be prevented in surgical patient because it causes serious problems such as delayed wound healing, bleeding, cardiac problems, deterioration of patient comfort, prolonged hospital stay, surgical site infection (SSI) and deaths.
Many guidelines state that the risk of surgical site infection increases three fold due to a decrease in central temperature of 1.9 C. According to the Guidelines for Safe Surgery published by the World Health Organization in 2009; maintaining normothermia during surgery is one of the ten steps intended to reduce the incidence of postoperative surgical site infection. The National Institute for Health and Care Excellence and the Association for Enhanced Recovery After Surgery (ERAS) recommend the maintenance of intraoperative normothermia to prevent surgical site infection.
Surgical nurse; should be aware of the causes of hypothermia and the complications that may occur during the planning, implementation and evaluation of a patient-specific, multi-faceted care; should check the body temperature before, during and after surgery and take precautions to prevent body temperature. Therefore, the body temperature of the patient should be monitored at regular intervals, the body temperature of the preventive interventions must be timely and effective implementation. The maintenance of normothermia in patients with perioperative procedures may reduce the incidence of complications due to hypothermia and may have a positive effect on the success and recovery of surgery.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control Group
Body temperature of the patients will be measured in the pre-operative service and in the waiting room. Sociodemographic characteristics form, preoperative, intra and postoperative evaluation forms will be completed. Body temperature, blood pressure, respiratory rate, heart rate and O2 saturation of the patients will be monitored every 15 minutes during the operation and postoperative 2 hours and data will be recorded on the data collection form.
No interventions assigned to this group
Underbody Blanket Group
Patients with hypothermia (\<36C) will be warmed by air blown underbody blanket before the surgical procedure. Warming procedure will be continued during and postoperative 2 hours of surgery. Body temperature will be measured by tympanic temperature gauge. Intravenous fluid, antiseptic solutions and irrigation fluids will be given to the patients during surgery by heating before administering. Body temperature, blood pressure, respiratory rate, heart rate and O2 saturation of the patients will be monitored every 15 minutes during the operation and postoperative 2 hours and data will be recorded on the data collection form.

Surgical Access Blanket Group
Patients with hypothermia (\<36C) will be warmed by air blown surgical access blanket before the surgical procedure. Warming procedure will be continued during and postoperative 2 hours of surgery. Body temperature will be measured by tympanic temperature gauge. Intravenous fluid, antiseptic solutions and irrigation fluids will be given to the patients during surgery by heating before administering. Body temperature, blood pressure, respiratory rate, heart rate and O2 saturation of the patients will be monitored every 15 minutes during the operation and postoperative 2 hours and data will be recorded on the data collection form.
