In this quasi-experimental study, 92 women undergoing cesarean section (emergency and elective surgery) that will undergo a surgical operation in the operating room of the Ali ibn Abi Taleb Hospital in Zahedan, will be targeted and will be included in the study. At first, 46 patients with a candidate for cesarean section who have criteria for entering the study will be selected and will enter the control group. In the routine control group, routine patients will receive routine care of the operating room, including dripping, dripping and infusion of fluids at the operating room temperature, and then transferred to the recovery room after surgery, and will be hospitalized in blanket blankets. Central temperature, blood pressure, pulse, and oxygen saturation of arterial blood, seven times, will be measured. Before starting anesthesia, after induction of anesthesia and before surgery, 30 minutes after surgery, after surgery, At the time of recovery, 0.5 hours and 1 hour after the patient's transfer to the recovery. In this group of patients, the necessary information will be entered into the information registration form on the basis of the data collection tool without any special intervention. After completing the sample size of the control group, 46 pregnant women eligible for inclusion criteria for the intervention group will be selected. Before the beginning, the goals and method of work will be explained to the people and written consent will be obtained from them. The intervention group women, after entering the operating room and placed on the surgical bed, are heated with a sterilized solution until the temperature reaches 32 ° C and eventually drips. Injections of injectable fluids will begin with a doctor prescription (warmed up at 38-40 ° C in the blood vessel). Upon completion of surgery, patients will be transferred from the operation bed to the recovery bed (which has been prepared in the recovery plan after the operation). So, half an hour before the patient is transferred to the recovery room, the bed will be prepared in the standard procedure, and two to three spa tubs will be placed in the bed to welcome the patient's bed at the appropriate temperature of the patient. These patients are similar to those in the control group in 7 cycles. Central temperature, blood pressure, pulse and arterial oxygen saturation were measured 30 minutes after anesthesia, after induction of anesthesia and before surgery. From the beginning of the surgery, after the completion of the surgery, it will be monitored at recovery time, 0.5 hours and 1 hour after the patient's transfer.
