Randomized Controlled Trial Comparative Study Clinical TrialProspective clinical evaluation of two combined spinal-epidural kits.
One hundred combined spinal epidural kits (Portex, n = 51, Mallinckrodt, n = 49) were evaluated clinically by twelve anaesthetists with respect to performance of the loss-of-resistance syringe, epidural needle and spinal needle, and success in establishing single-segment combined spinal-epidural anaesthesia for caesarean section. Similar components included a plastic loss-of-resistance device, a Tuohy epidural needle, 26 or 27 gauge pencil-point spinal needle and closed end, three-lateral-eye epidural catheter. The Mallinckrodt kit incorporated a "back-eye" design for exit of the spinal needle from the epidural needle. ⋯ Most anaesthetists preferred the Mallinckrodt kit packaging and the Portex loss-of-resistance syringe, although the latter may have been biased by familiarity with this device. The portex spinal needle was more likely to be felt penetrating the dura (P = 0.02) and aspiration of cerebrospinal fluid was more frequently described as easy (P = 0.01). The most common criticisms of both kits were difficulty controlling the spinal needle position after entry into the subarachnoid space and subjectively, a high degree of resistance to injection through the spinal needle.

Randomized Controlled Trial Clinical TrialRectal indomethacin potentiates spinal morphine analgesia after caesarean delivery.
This double-blind, randomized study was designed to evaluate the use of indomethacin (Indocid, MSD) following caesarean delivery performed under spinal anaesthesia. Thirty ASA I-II women presenting for elective caesarean were recruited. Spinal anaesthesia was performed in a standard manner using hyperbaric bupivacaine, fentanyl and morphine. ⋯ There were no reported adverse neonatal or maternal effects from the use of indomethacin. Rectal indomethacin use following caesarean delivery leads to significantly improved pain relief compared with placebo. The combination of spinal morphine and rectal indomethacin leads to high-quality postoperative analgesia.

Randomized Controlled Trial Comparative Study Clinical TrialPostspinal headache in Taylor's approach: a comparison between 21- and 25-gauge needles in orthopaedic patients.
A randomized study was carried out on 160 patients aged 30-60 years with the aim of finding a method of preventing postdural puncture headache (PDPH). In Taylor's lumbosacral approach to the subarachnoid space, two different needle sizes were used (21-gauge versus 25-gauge) for injecting the anaesthetic solution. ⋯ Patients with PDPH showed mild symptoms which disappeared in a short time and none needed epidural blood patching. The possibility of using larger needles, facilitating the execution of the block without increasing PDPH incidence, renders this technique particularly attractive in patients where the midline approach is not feasible, or when pencil-point needles are not available.
