Background: Hypothermia is one of the problems occurring during surgery, which can happen due to thermoregulation mechanism disorders and intake of low temperature IV fluids, and may cause increase in blood pressure, heart rate, intracranial pressure, oxygen consumption, pain, and discomfort to the patient. The rate of cesarean section in our country is three times more than the global standard. As one of the responsibilities of the nurse is patient's advocacy, s/he should support them. This study aimed to investigate the effect of pre-warmed intravenous fluids on prevention of hypothermia during general anesthesia in cesarean section.
Materials and methods: Sixty-two women undergoing elective cesarean section by general anesthesia were randomly allocated in two groups of intervention and control. Women in the intervention group received pre-warmed serum (37°C) while those in the control group received serum at room temperature (25.5°C). The core body temperature and some hemodynamic parameters of the participants were assessed during the operation.
Results: The mean of pulse rate, systolic blood pressure, diastolic blood pressure, and arterial O2 saturation in the two groups were not statistically significant (P > 0.05). But the mean of mothers' core body temperature at the end of anesthesia in the intervention and control groups were 36 ± 0.5°C and 35.34 ± 0.6°C, respectively (P < 0.05).
Conclusion: Infusion of pre-warmed serum (37°C) would prevent intraoperative hypothermia and improve the nursing care for women who undergo cesarean section by general anesthesia.
