Randomized Controlled Trial Comparative Study Clinical TrialAmethocaine-lidocaine cream, a new topical formulation for preventing venopuncture-induced pain in children.
The aim of this study was to compare the effectiveness of 3 anesthetic creams in relieving venous puncture-related pain in children. ⋯ All 3 creams proved to be effective in relieving venous puncture pain in children. EMLA presented a longer latency period, 4% amethocaine showed the highest percentage of untoward effects, and AMLI exhibited a shorter latency period than EMLA, while having fewer adverse effects than 4% AMET and EMLA.

Randomized Controlled Trial Clinical TrialIntrathecal hyperbaric bupivacaine dose response in postpartum tubal ligation patients.
Because of its short duration, hyperbaric lidocaine has been a popular intrathecal drug to provide anesthesia for postpartum tubal ligation (PPTL). However, reports of transient symptoms associated with its use have prompted the search for alternative intrathecal local anesthetics for short procedures. Hyperbaric bupivacaine is rarely associated with transient neurologic symptoms, and we designed this study to determine the optimal dose of bupivacaine for PPTL that assures adequate sensory block and allows the patient the shortest recovery time. ⋯ Hyperbaric bupivacaine 7.5 mg injected in the lateral position provides adequate surgical anesthesia for PPTL with a minimal duration of motor block and recovery time.

Percutaneous electrode guidance: a noninvasive technique for prelocation of peripheral nerves to facilitate peripheral plexus or nerve block.
Typically, peripheral nerve block is done by approximating nerve location, usually by use of anatomical landmarks. Precise nerve location has been done by needle exploration. A new method, percutaneous electrode guidance (PEG) of the block needle, was performed. A transcutaneous stimulating cylindrical electrode was used to indent the skin, locate the underlying nerve, and guide a block needle near it. ⋯ A smooth, metal-tipped electrically shielded skin electrode probe can be used to comfortably and accurately indent the skin over a desired nerve or plexus, define its anatomical course, and subsequently guide a block needle near it.
