Clinical study of air pressure uterus bracket in preventing supine hypotensive syndrome during C-section under combined spinal-epidural anesthesia

This study aimed to investigate the effects of air pressure uterus bracket (APUB) in preventing supine hypotensive syndrome (SHS) during C-section under combined spinal-epidural anesthesia (CSEA). A total of 90 pregnant women who underwent CSEA C-section were selected and randomly divided into the control group (group A) and the experiment group (group B), with 45 patients in each group. The patients in group A were quickly placed in the supine position after fixing the epidural catheter; the patients in group B were attached with APUB after fixing the epidural catheter, and the bracket airbag was pressurized. The incidences of SHS and intraoperative maternal comfort (IMC) between the two groups were then compared. The incidence of SHS between the two groups was significantly different (blood pressure decreased by 30 mmHg: 57.78% in group A and 24.44% in group B, P<0.05); the IMC conditions between the two groups were also significantly different (comfort rate: 60.00% in group A and 91.11% in group B, P<0.05). APUB can effectively prevent SHS during CSEA C-section.
