Investigation of the Effect of Operating Room Environment and Cesarean Section Orientation on Physiological Parameters (BP, Heart Rate, Respiration) in Candidates for Cesarean Section in Shiraz: A Clinical Trial Study

Background: Changes in physiological parameters in pregnant women are important factors in mothers who are candidates for cesarean section. Objective: The aim of the present study was to investigate the effect of an operating room and cesarean section orientation on the physiological parameters (BP, heart rate, respiration) of pregnant women undergoing cesarean section. Materials and Methods: This clinical trial study was performed on 80 pregnant women referring to a cesarean section in hospitals affiliated to Shiraz University of Medical Sciences in 2019. The samples were randomly divided into two control (n = 40) and intervention groups (n = 40). The intervention group participated in 4 sessions of training classes. The control group used routine hospital training. The parameters were measured before and after the intervention in two groups. Data were analyzed using SPSS software (version 21), independent T-test, and analysis of covariance. Results: The mean of post-training blood pressure in the intervention group, i.e., 82.78 (7.86), and the control group, i.e., 84.08 (7.44), was not statistically significant (p < .487). After the intervention, the mean heart rate in the intervention group, i.e., 82.15 (8.10) and in the control group, i.e., 83.43 (8.54), was statistically significant (p <0.0001). After the intervention, the mean respiratory rate in the intervention group was 94.28 (0.96) and in the control group was 75.96 (1.08) (P <0.0001). Conclusion: Although the patient's operating room and cesarean section orientation did not affect mothers' mean blood pressure, it reduced the mean of their heart rate and respiratory rate. It is important for medical staff to play an important role in identifying important strategies in managing the anxiety of pregnant women in order to improve their physiological indicators. This study was also registered in the Iranian Registry of Clinical Trials (IRCT code: 20130710013940N6).
