A comparison of the 24-gauge Sprotte and Gertie Marx spinal needles for combined spinal-epidural analgesia during labor.

摘要: Background: Prior experience with the combined spinal-epidural technique (CSE) for labor analgesia demonstrated a high (up to 14%) failure rate because of obtain cerebrospinal fluid (CSF) or lack response appropriate doses intrathecal sufentanil. The current study was designed test whether longer needle shorter side port (Gertie Marx® needle; 127 mm long) would eliminate failures CSF compared we had used previously (Sprotte® 120 long). Methods: Seventy-three parturients were randomly assigned have CSE performed one these two needles. After identifying epidural space an 18-gauge Touhy at L2-L3 L3-L4 interspace, spinal introduced through until penetration dura felt maximally inserted. If no obtained, alternate tried. obtaining CSF, 10 pg sufentanil diluted in 1.8 ml saline injected. Verbal pain scores (0-10) obtained every 5 min 30 min. Results: Failure occurred six times Sprotte group none Gertie Marx (P < 0.05). In all group, subsequently proved successful CSF. There differences between groups. Conclusions: extra length 127-mm resulted higher success when technique. Side design not factor influencing this clinical setting.
