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.

Randomized Controlled Trial Clinical TrialThe addition of epinephrine to subarachnoid administered hyperbaric bupivacaine with fentanyl for cesarean delivery: the effect on onset time.
This study examines the effect of epinephrine on the time to achieve a T4 sensory level when added to a hyperbaric bupivacaine-fentanyl mixture for spinal anesthesia. ⋯ The onset time to T4 is related inversely to patient weight, and epinephrine (100 micrograms and 200 micrograms) delays the onset of sensory block to T4 when administered with subarachnoid hyperbaric bupivacaine-fentanyl.

Randomized Controlled Trial Clinical TrialThe antiemetic efficacy and safety of prophylactic metoclopramide for elective cesarean delivery during spinal anesthesia.
The efficacy and safety of intravenous metoclopramide administered prophylactically before elective cesarean delivery under spinal anesthesia was studied. ⋯ Metoclopramide administered before induction of spinal anesthesia for cesarean delivery appears to significantly reduce both pre- and postdelivery emetic symptoms without apparent adverse effects on mother or neonate.

Randomized Controlled Trial Clinical TrialAdding clonidine to mepivacaine prolongs the duration of anesthesia and analgesia after axillary brachial plexus block.
This study evaluates the effects of clonidine added to mepivacaine on the duration of anesthesia and analgesia after axillary brachial plexus block. ⋯ One hundred fifty micrograms clonidine added to mepivacaine for brachial plexus block prolongs the duration of anesthesia and analgesia. Our results suggest that this effect of clonidine is local rather than systemic.
