The effect of various pressure of pneumatic uterine bracket by using saccule sterine external stent on incidence of supine hypotensive syndrome
open access
Abstract
Objectives: The saccule uterine external stent with a pneumatic uterine bracket reportedly prevents the incidence of supine
hypotension syndrome (SHS) during cesarean section under combined spinal — epidural anesthesia (CSEA). However, the
preventive effect is affected by the pressure within pneumatic uterine bracket. This study aims to explore the optimal pressure.
Material and methods: One hundred forty-eight pregnant women were selected and randomly divided into three groups:
Group A (the control group, n = 49), Group B (n = 49), and Group C (n = 50). The pressure within pneumatic uterine bracket
was set at 240 mmHg, 260mmHg, and 280mmHg, respectively, during cesarean section under CSEA for participants in
groups A, B and C. The intraoperative comfort rate and incidence of SHS were recorded.
Results: No significant difference in the anesthetic efficacy was observed among the three groups (p > 0.05). However, there
was a significant difference in the occurrence of SHS, with a reduction of 30 mmHg in blood pressure. The incidence of SHS
belong the three groups showed significant differences (36.73% in Group A, 18.37% in Group B and 18.00% in Group C,
p < 0.05). In addition, significant differences (p < 0.05) in the intraoperative comfort rate were also found among the three
groups, with the comfort rate of 69.39% in group A, 91.84% in group B and 90.00% in Group C.
Conclusions: The optimal pressure within pneumatic uterine bracket for preventing SHS hypotension is about 260 mmHg.
These findings might contribute to the prevention of SHS.
