Randomized Controlled Trial Clinical TrialContinuous interscalene brachial plexus block for postoperative analgesia following shoulder surgery.
Severe postoperative pain is a well-known problem following shoulder surgery. This study evaluates the clinical efficacy of continuous interscalene brachial plexus block, patient-controlled analgesia, and morphine (i.v. and i.m.) for postoperative analgesia in this setting. ⋯ Successful continuous interscalene brachial plexus block provides very good pain relief following shoulder surgery and is superior to the other methods studied. However, we were unable to demonstrate a correlation between VAS pain scores and stress indicators in metabolic, circulatory and respiratory parameters.

Randomized Controlled Trial Clinical TrialBilateral infraorbital nerve block is superior to peri-incisional infiltration for analgesia after repair of cleft lip.
Cleft lip repair is a common operation in infants and requires that the child is pain-free during the postoperative period so that handling does not affect the integrity of the delicate surgical site. This study was designed to compare the efficacy and duration of effect of 0.125% bupivacaine given preoperatively as a bilateral infraorbital nerve block with peri-incisional infiltration of the same local anaesthetic for postoperative analgesia in cleft lip repair. It was a randomised, double blind, prospective study in 30 children aged 4-20 months (ASA grade 1). ⋯ The analgesic requirement in group B became significant at two hours postoperatively, while group A had significant analgesic requirements only after eight hours. The significant rise in heart rate and blood pressure that accompanied tracheal intubation in both groups suggested that while both methods of analgesia may be adequate to prevent responses to skin incision, they do not substitute for adequate systemic analgesia during the operation. We conclude that infraorbital nerve block with 0.125% bupivacaine provides better and more prolonged analgesia than peri-incisional infiltration in cleft lip repair.

Comparative Study Clinical Trial
The effect of compression and regional anaesthetic block on referred pain intensity in humans.
The mechanisms underlying local and referred muscle pain are poorly understood. The aim of this experiment was to determine to which degree referred pain is dependent on peripheral or central mechanisms. This was studied by blocking sensory input from the referred pain area. ⋯ In the combined nerve block experiment, a significant reduction of referred pain intensity (38.5%) was seen after 20 min and until the release of the tourniquet. There was no significant difference in the referred pain intensity between the two types of blocks. The present findings suggest that both peripheral and central mechanisms play a role in referred pain and that the myelinated fibres mediate the peripheral component.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the Mogen and Gomco clamps in combination with dorsal penile nerve block in minimizing the pain of neonatal circumcision.
1) To compare the Mogen and Gomco clamps with regard to pain experienced during neonatal circumcision, and 2) to assess neonatal circumcision pain with and without dorsal penile nerve block (DPNB). ⋯ DPNB is effective in reducing neonatal circumcision pain with either the Mogen or the Gomco clamp. For a given anesthesia condition, the Mogen clamp is associated with a less painful procedure than the Gomco. The Mogen clamp with DPNB causes the least discomfort during neonatal circumcision.
