5. Study Description

Brief Summary
During the cesarean section; Hypothermia can be seen due to reasons such as anesthesia, premedication drugs, cold operating room environment, exposure of tissues and organs, and use of cold intravenous fluids. Hypothermia associated with cesarean may affect maternal and fetal health negatively. As a result of hypothermia, coagulopathy, infection, undesirable cardiac events that cause an increase in oxygen consumption, delay in postoperative recovery and wound healing, postoperative nausea and vomiting, chills and relief may be observed in the mother. Newborns born from hypothermic mothers have lower body temperature, pH and Apgar scores. It is important to evaluate all women in terms of risk factors in the preoperative period in the prevention of hypothermia and complications related to hypothermia. Prevention of hypothermia, which has negative effects on maternal and newborn health, is one of the risks that the nurse can address independently. Therefore, this research; In order to determine the effect of heating different body areas using compressed air heating technique during cesarean section on hypothermia, tremor, thermal comfort, postpartum comfort and maternal satisfaction, a parallel group was planned as a randomized controlled trial. The study is planned to be conducted in Hacettepe University Adult Hospital Gynecology and Obstetrics Department delivery room and obstetrics service. Research data, Introductory Information Form (Appendix 1), Obstetric and Postpartum Features Form (Appendix 2), Patient Monitoring Form (Appendix 3), Termal Comfort Perception Scale (Appendix 4), Shivering Level Diagnostic Form (Appendix 5), LATCH Breastfeeding The Diagnostic and Measurement Tool (Appendix 6) will be collected using the Visual Analogue Scale (Appendix 7) and the Thermal Comfort Scale that will be developed by the researchers. Pregnant women who meet the inclusion criteria will be included in the research. Women will be divided into 4 groups as the lower extremities are heated, the upper extremities are heated, the whole body is heated, and the control group. According to the group of women; It will be heated 30 minutes before surgery and 30 minutes after surgery with lower limb, upper limb or whole body. Women in the control group will not be heated.
Detailed Description
This study was planned as a parallel group randomized controlled study in order to determine the effect of heating different body parts using forced air warming technique during cesarean section on maternal hypothermia, shivering, thermal comfort, the Apgar score of the newborn and breastfeeding. In the preparation phase of the research; Determining the rate of hypothermia in women applying to the delivery room of Hacettepe University Adult Hospital for planned cesarean section, determining and procuring the devices to be used in the study, and establishing experimental and control groups will be realized. Body temperatures of women will be measured for 2 weeks in order to determine the rate of hypothermia in women who have had cesarean section in the institution where the study will be conducted. Body temperature of women will be started 30 minutes before the cesarean section and will be measured every 15 minutes until 30 minutes after the operation. By determining the prevalence of hypothermia after cesarean section in women; It is aimed to reveal the necessity of heating with compressed air heating technique. Women are admitted to the delivery room 60-90 minutes before the cesarean operation. The Introductory Information Form will be applied by the researcher using face-to-face interview before the women are admitted to the operating room. 30 minutes before the operation, women's body temperature, shivering, blood pressure, pulse and respiratory values will be evaluated every 15 minutes and recorded on the Patient Monitoring Form. In addition, the Temperature Comfort Scale, which will be developed by the researchers, will be applied by face to face interview method. Applications During Cesarean Surgery During the operation, women's body temperature, temperature comfort score, shivering, blood pressure, pulse, respiration and SpO2 values will be evaluated every 15 minutes and recorded on the Patient Monitoring Form. With the birth of the baby; The newborn's body temperature, 1st and 5th minute Apgar score will be evaluated and recorded on the Obstetric and Postpartum Characteristics Form. Applications to be Made Within 30 Minutes After Cesarean Surgery After the cesarean operation, women will be monitored in the recovery unit for 30 minutes. Body temperature, temperature comfort score, shivering, blood pressure, pulse, respiration and SpO2 values will be evaluated every 15 minutes after the women are admitted to the recovery unit and recorded on the Patient Monitoring Form. In addition, the Temperature Comfort Scale, which will be developed by the researchers, will be applied to women 30 minutes after the operation for the second time. The pain level of women will be evaluated with the Visual Pain Scale 30 minutes after surgery. In the institution where the research will be conducted, all women are given a heated blanket at 70 0C when they feel cold and shiver after cesarean section. The number of covers used varies depending on the demand of the woman. Researcher women will not interrupt this routine care they receive. The number of heated covers used by women will be recorded on the Obstetric and Postpartum Characteristics Form. Applications to be Performed in Obstetrics and Gynecology Service after Cesarean Operation Information such as the need for analgesia, time to start breastfeeding, first mobilization time, gas, stool and urine output will be obtained from the patient file and recorded in the Obstetric and Postpartum Characteristics Form. The pain level of women will be evaluated repeatedly with the Visual Pain Scale (VAS) at the 24th hour after surgery. Due to the effect of anesthesia and the administration of analgesics upon the request of the doctor within the first day after cesarean operation, the VAS score after 24 hours will be evaluated. Before discharge, the development of postpartum complications in a woman will be evaluated and recorded on the Obstetric and Postpartum Features Form. At Hacettepe University Adult Hospital Gynecology Service, the breastfeeding status of mothers of newborns is evaluated using the LATCH Breastfeeding Diagnostic and Measurement Tool. Effective breastfeeding score assessed by the nurses: LACTH score will be evaluated and recorded on the Obstetric and Postpartum Characteristics Form.
