Effect of wire-reinforced epidural catheter for epidural labor analgesia

Abstract

Objective To evaluate the effects of wire-reinforced epidural catheter for epidural labor analgesia. Methods A total of 160 maternal with epidural labor analgesia in the Third Affiliated Hospital of Zhengzhou University for epidural labor analgesia were selected, aged 22 to 40 years old, with body weight of 50 to 75 kg, and ASA grade II. Maternal women were randomly divided into two groups using random number table method, with 80 patients in each group. Group A underwent epidural anesthesia with a common epidural catheter, and group B underwent an epidural block with a wire-reinforced epidural catheter. The complications of the two groups of maternal epidural anesthesia were observed and recorded. The visual analogue scale (VAS) score was evaluated by epidural administration after 0.5, 2, 4, and 8 h of epidural anesthesia. Results In group B, the incidence of tube obstruction, abnormal feeling during catheterization, blood withdrawal, drug injection resistance and post-tubular sensation abnormalities were 5%, 3%, 0, 0, 0, respectively, all of which were lower than those in group A (P 0.05). The VAS score in group B after 2, 4, 8 h of epidural anesthesia were lower than those in group A (P<0.05). Conclusions The wire-reinforced epidural catheter placement is smoothly, the maternal has less discomfort. And it can reduce the nerve and blood vessel catheter damage, and effectively improve the analgesic effect of epidural labor analgesia. Key words: Wire-reinforced epidural catheter; Continuous extramembranous block; Painless childbirth
