The effectiveness of pre-warm intravenous fluids on prevention of intraoperative hypothermia in surgical patients
Main Article Content
Abstract
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 surgery in our country is higher than the global standard. As one of the responsibilities of the nurse is patient's advocacy, should support them. This study aimed to investigate the effectiveness of pre-warm intravenous fluids on prevention of hypothermia in patient with surgery.
Materials and Methods: Twenty-eight patients undergoing elective surgery by general anesthesia were randomly allocated in two groups of intervention and control. All selected patients in the intervention group received pre-warm 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 Oxygen saturation in the two groups were not statistically significant (p>0.05). But the mean of patient’s core body temperature at the end of anesthesia in the intervention and control groups were 20±0.5°C and 35.34±0.6 °C, respectively (p<0.05).
Conclusion: Infusion of pre-warm serum (37 °C) would prevent intraoperative hypothermia and improve the nursing care for patients who are undergo surgical section.
