Arrow Flextip Plus TM Wire Reinforced Epidural Catheters Decrease Complications in Chinese Obstetric Patients
Abstract Number: T-06
Abstract Type: Original Research
Backgroud: Transient paraesthesia and inadvertent epidural vein injury are most common complications during epidural catheter placement. The Arrow Flextip PlusTM is an soft-tipped, flexible catheters, which designed for possible reduction of these complications. To date, there still few published Chinese studies comparing traditional multiport catheters (BD DurasafeTM epidural catheters) and the novel wire reinforced epidural catheters （Arrow Flextip PlusTM ）in terms of analgesic efficacy or the incidence of complications in obstetric patients.
Methods: This prospective, randomized, unblinded clinical trial (n=182) was to compare the incidence of inadvertent epidural vein injury, transient paraesthesia and accidental intrathecal catheter placement in pregnant women scheduled for selective caesarean section receiving combined spinal-epidural anesthesia (CSEA) with either the Arrow Flextip PlusTM or the BD DurasafeTM epidural catheters.
Results: In the novel wire reinforced epidural catheters group (Arrow Flextip PlusTM ), the incidence of both paraesthesia and epidural vein injury were 0%, significantly lower than that of traditional multiport catheters group (BD DurasafeTM epidural catheters), it was 11.7% and 15.9% respectively (p = 0.000); the resistance of epidural catheter insertion was similar in both groups (p = 0.623).
Conclusion: This novel wire reinforced epidural catheters did reduce the incidence of both transient paraesthesia and inadvertent epidural vein injury to 0%, and provided high success epidural catheter placement, improved Chinese parturients’ comfort during epidural puncture procedure and perioperative safety.
