Randomized Controlled Trial Comparative Study Clinical TrialReevaluation of the sciatic nerve block.
Sciatic nerve blocks are perceived as unreliable, technically demanding, and uncomfortable. With strict criteria to define success rates, we designed a study to examine the efficacy of two techniques of sciatic nerve block. ⋯ Patient acceptance was excellent.

Case Reports Randomized Controlled Trial Clinical TrialPostdural puncture headache after continuous spinal anesthesia with 18-gauge and 20-gauge needles.
To evaluate the incidence of postdural puncture headache (PDPH) associated with continuous spinal anesthesia, 200 male patients (mean age 65 years) were randomly assigned to receive spinal anesthesia in one of three ways: group 1, 50 patients with an 18-gauge Tuohy-Schliff needle/20-gauge catheter combination; group 2, 50 patients with a newly developed 20-gauge Quincke point needle/24-gauge catheter combination; and group 3, 100 patients (control group, single injection spinal anesthesia) with a 22-gauge Quincke point needle. ⋯ The incidence of PDPH associated with continuous spinal anesthesia is acceptable in appropriate clinical circumstances, but large initial doses of local anesthetic should not be administered.

Randomized Controlled Trial Clinical TrialThe effect of cardiac output on intraoperative blood loss during total hip arthroplasty.
It is not clear whether cardiac output affects intraoperative blood loss under epidural hypotensive anesthesia. ⋯ Cardiac output is not a factor influencing blood loss during hypotensive epidural anesthesia in elderly patients undergoing primary total hip arthroplasty.

Randomized Controlled Trial Comparative Study Clinical TrialInteradductor approach to obturator nerve blockade for spastic conditions of adductor thigh muscles.
The authors describe a new approach for the management of adductor muscle spasm associated with multiple sclerosis and paraplegia. ⋯ The interadductor approach is a new approach based on the anatomy of the obturator nerve trunk, which, though in the obturator canal, is shielded by its osseous part from the anteroposterior perspective of the traditional approach. The interadductor approach allows needle positioning inside the obturator canal through a mediolateral perspective, thus facilitating the blockade of the obturator nerve trunk before it branches immediately outside the canal. The new approach proved to be successful, reproducible and without complications.
