Randomized Controlled Trial Comparative Study Clinical Trial
Lateral popliteal sciatic nerve block compared with ankle block for analgesia following foot surgery.
The purpose of this study was to compare postoperative analgesia after foot surgery in patients anaesthetised either with popliteal sciatic nerve block or ankle block. In a prospective study, 40 patients scheduled for foot surgery involving osteotomies were allocated randomly into one of two groups. Following induction of general anaesthesia, Group PS (n = 21) received a lateral popliteal sciatic nerve block and Group AB (n = 19) received an ankle block. ⋯ The ankle block appeared to be more reliable, providing more consistent analgesia in the PAR. Postoperative analgesia in Group PS lasted a median of 18.0 hr and in Group AB lasted 11.5 hr (P < 0.05). Both techniques provided effective analgesia after discharge home and high levels of patient satisfaction.

Comparative StudyThe contribution of the obturator nerve block in the transurethral resection of bladder tumors.
This study was designed to evaluate the efficacy of local block of the obturator nerve to avoid it's stimulation during transurethral resection (TUR) or tumors localised on the lateral bladder wall. Forty-five patients were studied, in whom the TUR operations were performed under spinal anaesthesia. ⋯ In the first group no stimulation was observed while in 5 patients of the second group was not possible to totally resect the tumor due to the persistent stimulation of the obturator nerve. In conclusion the local block of the obturator nerve is an effective method to avoid it's stimulation, easily performed and without complications.

During peripheral nerve block, local anesthetic (LA) penetrates within and along the nerve to produce the observed functional deficits. Although much is known about the kinetics and steady-state relation for LA inhibition of impulse activity in vitro in isolated nerve, little is known about the relation between functional loss and intraneural LA content in vivo. This study was undertaken to investigate the relation of functional change to intraneural LA. ⋯ During peripheral nerve block only a small amount of injected LA penetrates into the nerve. The intraneural content of LA correlates with the depth of functional block.

A local anaesthetic block of branches of the greater auricular and auriculotemporal nerves was used to facilitate the extraction of retained butterfly backs and ear-ring studs. A total of 28 ear blocks were performed on 26 patients. ⋯ Assessment of analgesia was not possible in one 5-year-old child. We recommend this quick and simple technique for removal of retained ear-rings, particularly when there is associated soft tissue infection, in which case infiltration of local anaesthetic into the earlobe is contraindicated.
