Randomized Controlled Trial Comparative Study Clinical TrialTechnical and light microscopic comparison of four different small-diameter catheters used for continuous spinal anesthesia.
Recently several manufacturers developed ultra-thin catheters for continuous spinal anesthesia. Their use may be associated with technical problems. ⋯ The use of the 32-gauge polyurethane catheter was associated with problems that limit its clinical usefulness. Nylon and polyimide catheters with stainless steel stylets were more resistant to stretching. The nylon catheter was most resistant to adhesion of fibrinous material.

Randomized Controlled Trial Clinical TrialPerioperative analgesia with subarachnoid sufentanil administration.
Thirty-seven ASA Physical Status I parturients undergoing elective cesarean delivery were evaluated to determine the effects of subarachnoid sufentanil administration. ⋯ Duration of complete analgesia and duration of effective analgesia were prolonged significantly in all patient groups receiving sufentanil as compared to control groups receiving no narcotic. Pruritus was significantly increased in patient groups receiving subarachnoid sufentanil. Respiratory depression was not observed in any patient studied. One- and five-minute Apgar scores; umbilical, venous, and arterial blood gas results; and Early Neonatal Neurobehavioral Scale results were all within normal limits and were not significantly different among the groups.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of Sprotte and Quincke needles with respect to post dural puncture headache and backache.
The objective of this study was to compare 24-gauge Sprotte and 25-gauge Quincke needles with respect to post dural puncture headache and backache. ⋯ Our data indicate that Quincke needles should not be used with the needle bevel inserted perpendicular to the dural fibers. The Sprotte needle does not solve the problem of post dural puncture headache and backache.
