Investigation of effect of blood pressure and heart rate changes in different positions (lying and sitting) on hypotension incidence rate after spinal anesthesia in patients undergoing caesarean section

Abstract

Due to the relatively high prevalence of hypotension (20% -40%) after spinal anesthesia as well as the adverse effects of hypotension on mother and baby, it is better to prevent hypotension as much as possible. Therefore, this study is aimed to determine the relationship between postural blood pressure and heart rate changes and hypotension incidence rate after spinal anesthesia in cesarean section.63 women aging18 to 45years old with fullterm pregnancy, who were candidate for caesarean section with spinal anesthesia, entered the study. Afterwards, the diastolic, systolic, and mean arterial pressures as well as the heart rate (pulse) in different positions (sitting, lying, and left lateral) were measured. After spinal anesthesia, the patients' blood pressure was measured and recorded every minute until the10thmin, then every 3 minute until the15thmin, and then every 5 minute until the end of cesarean section. Data analysis was performed using SPSS (ver. 19) software, descriptive statistics, one-way ANOVA, and post hoc Bonferroni test. In this study, the hypotension incidence rate was 30% and the orthostatic variation rate of the systolic blood pressure in more than half of the people was between 4.39 to 13.49psi, which showed the highest variation compared to the diastolic pressure, mean arterial blood pressure (or: mean arterial pressure [MAP]), and heart(pulse). Considering the correlation coefficient of 0.27, the systolic blood pressure in the lateral position has the highest relationship with the incidence of hypotension. The postural systolic blood pressure changes in patients prior to the spinal anesthesia can be a predictive factor for the post-spinal hypotension incidence.
