Abstract:
Objective To evaluate the effect of domestic wire-reinforced epidural catheter on the occurrence of adverse events during epidural block.Methods Three hundred ASA Ⅰ or Ⅱ patients of both sexes,aged 18-64 yr,weighing 41-78 kg,scheduled for elective operations under combined spinal-epidural anesthesia,were randomly divided into 3 groups (n =100 each):polyvinyl chloride epidural catheter group (group A),imported wire-reinforced epidural catheter group (group B) and domestic wire-reinforced epidural catheter group (group C).Combined spinal-epidural anesthesia was performed routinely.The corresponding epidural catheter was inserted in each group.The catheterization without difficulty,paresthesia during catheterization,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,intravascular catheter insertion,injection obstruction,easiness during removal of the catheter,bleeding after removal,postoperative paresthesia and epidural hematoma within 1 week after operation were recorded.Results Compared with A group,the incidences of paresthesia during catheterization,the number of patients in whom blood or cerebrospinal fluid was withdrawn from the epidural catheter,injection obstruction and postoperative paresthesia were significantly decreased (P ＜ 0.05),and no significant change was found in the other parameters in B and C groups (P ＞ 0.05).There was no significant difference in all the parameters between B group and C group (P ＞ 0.05).Conclusion Domestic wire-reinforced epidural catheter can decrease the occurrence of catheterization-induced damage to the nerve and blood vessels and the efficacy is comparable with that of imported wire-reinforced epidural catheter.
