Post-spinal anesthesia hypotension is a common complication in pregnant women undergoing cesarean section, affecting fetal blood flow. This quasi-experimental study Two group Pretest-Posttest design aimed to compare the incidence of post-spinal hypotension between
a triangular hip support pillow and those receiving standard nursing care during cesarean delivery under spinal anesthesia. This study included 128 pregnant women who underwent cesarean section with spinal anesthesia, who were purposively recruited and allocated into an experimental group (n = 64) and a control group (n = 64). The experimental group received left uterine displacement using a triangular hip support pillow, whereas the control group received standard perioperative nursing care. Research instruments included the triangular hip support pillow, a demographic and clinical data record form, a spinal anesthesia record form, and serial maternal blood pressure recording forms obtained before and after spinal anesthesia at predetermined time intervals.
Data was analyzed using descriptive statistics and the Wilcoxon rank-sum test. The results showed that:
1. significant differences in systolic blood pressure between the two groups at 1, 5, 10, and 15 minutes following spinal anesthesia (p-value = .019, < .001,< .001, and p-value = .001, respectively).
2. Significant differences in diastolic blood pressure were also observed at 1, 5, and 10 minutes after spinal anesthesia (p-value < .001, < .001, and p-value = .006 respectively).
In conclusion, the use of a triangular hip support pillow to achieve left uterine displacement effectively reduces the incidence of post-spinal hypotension in pregnant women who undergo cesarean section under spinal anesthesia. This simple, low-cost, and practical intervention can be incorporated into routine perioperative nursing practice to enhance the safety of both mothers
and newborns.
