Effects of domestic wire-reinforced epidural catheter on complications related to anesthesia during labor analgesia / 中华麻醉学杂志

ABSTRACT

Objective To evaluate the effects of the domestic wire-reinforced epidural catheter on complications related to anesthesia during labor analgesia.Methods A total of 2 407 parturients,aged 18-40 yr,weighing 50-100 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective operations under combined spinal-epidural anesthesia for labor analgesia,were divided into 2 groups using a random number tablecomnon epidural catheter group (group Ⅰ,n=1 203) and wirereinforced epidural catheter group (group Ⅱ,n=1 204).After successful epidural puncture,the appropriate amount of local anesthetics was injected into the subarachnoid space,and the corresponding epidural catheter was then inserted,and the depth was 3 em.Paresthesia during catheterization,unexpected catheter displacement,difficult extubation,catheter bending,epidural bleeding,successful insertion at first attempt,successful insertion time,the number of successfully delivered doses and consumption of patientcontrolled analgesia solution were recorded.The patients were followed up after operation for nerve damage.Results Compared with group Ⅰ,the incidence of paresthesia during catheterization,unexpected catheter displacement and catheter bending was significantly decreased,the occurrence of epidural bleeding was reduced,the success rate of insertion at first attempt was increased,successful insertion time was shortened,the incidence of difficult extubation was increased (P＜0.05 or 0.01),and no significant change was found in the number of successfully delivered doses,consumption of patient-controlled analgesia solution or incidence of nerve damage after operation in group Ⅱ (P＞0.05).Conclusion Complications related to anesthesia are reduced when the domestic wire-reinforced epidural catheter is used for labor analgesia.
