Infraclavicular brachial plexus block effects on respiratory function and extent of the block.
Axillary block is devoid of severe respiratory complications. However, incomplete anesthesia of the upper limb is the main disadvantage of the technique. Theoretically, the more proximal infraclavicular approach would produce a more extensive block without the risk of pneumothorax. However, neither its effects on respiratory function nor a detailed characterization of the extent of neural block has been assessed. The goal of this study was to evaluate the possible changes in respiratory function and also the extent of the block after infraclavicular block. ⋯ Infraclavicular block does not produce a reduction in respiratory function.

Injection of the piriformis muscle by fluoroscopic and electromyographic guidance.
There is not a universally accepted single technique for injection of the piriformis muscle that has validated exact placement of the needle tip within the piriformis muscle. ⋯ Using this methodology, injections on 17 occasions in 11 patients resulted in needle placement within the piriformis muscle.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia in children using preemptive retrobulbar block and local anesthetic infiltration in strabismus surgery.
Postoperative pain management in pediatric strabismus patients is infrequently studied. Pediatric patients can be mobilized earlier if postoperative pain is minimized. In this study, two different regional anesthetic techniques, retrobulbar block and local infiltration, were compared with a "no block" control group for the postoperative management of pain in pediatric patients undergoing elective strabismus surgery. ⋯ Because there was no significant difference in terms of postoperative analgesia in the retrobulbar block or subconjunctival local anesthetic infiltration groups compared with the control group, we suggest that conventional methods of pain treatment are adequate for postoperative analgesia in strabismus surgery.

Randomized Controlled Trial Comparative Study Clinical TrialClonidine added to bupivacaine-epinephrine-sufentanil improves epidural analgesia during childbirth.
A double-blind study was conducted to assess the efficacy and the side effects of a low dose of clonidine added to an epidural injection of bupivacaine and epinephrine, with or without sufentanil. ⋯ The addition of a low dose of clonidine to an epidural injection of bupivacaine with epinephrine and sufentanil provides better analgesia during labor, while keeping the side effects minimal and of minor clinical importance.
