Randomized Controlled Trial Comparative Study Clinical TrialA comparison of a single-stimulation lateral infraclavicular plexus block with a triple-stimulation axillary block.
A single-stimulation infraclavicular brachial plexus block (ICB) is safe and easy to perform, although underused. This technique was compared with a triple-stimulation axillary block (AxB). ⋯ A single shot ICB is equally effective as a triple-nerve stimulation AxB.

Randomized Controlled Trial Clinical TrialLidocaine priming reduces tourniquet pain during intravenous regional anesthesia: A preliminary study.
Tourniquet pain often limits the use of intravenous regional anesthesia (IVRA). Intravenous (IV) lidocaine has been shown to be effective in the management of acute and neuropathic pains. We tested the hypothesis that a priming IV injection of lidocaine might have an analgesic effect on tourniquet pain during IVRA. ⋯ Priming IV lidocaine when compared with isotonic saline is effective in reducing tourniquet pain in IVRA.

Randomized Controlled Trial Clinical TrialThe effect of intrathecal epinephrine on epidural infused analgesics during labor.
In order to prolong labor analgesia, one may add intrathecal epinephrine to the combination of bupivacaine and fentanyl. In this study, we tested the hypothesis that the addition of intrathecal epinephrine would lessen the requirement for a rescue dose of epidural analgesia during labor. ⋯ The addition of epinephrine to intrathecal bupivacaine-fentanyl lessened the requirement for additional epidural analgesia without increasing hypotension, nausea, or pruritus. However, the incidence of motor block may be increased without labor prolongation.

Clinical TrialContinuous peripheral nerve blocks with stimulating catheters.
This study evaluated the efficacy of stimulating catheters used for continuous peripheral nerve blocks as a means of immediate verification and confirmation of correct catheter position. ⋯ The ability to electrostimulate nerves using an in situ catheter increases success rate in catheter placement for continuous peripheral nerve blocks. Further controlled investigations are necessary to compare this technique with more conventional methods in terms of cost and utility for various peripheral nerve blocks.

Cervical epidural block is useful in the management of a variety of acute, chronic, and cancer-related pain syndromes involving the head, face, neck, and upper extremities. Knowledge of the depth from the skin to the cervical epidural space (DSES) may be helpful when performing cervical epidural block and may reduce the possibility of complications. We studied DSES in adults and its relationship with patient age, height, weight, and neck circumference. ⋯ DSES varies with cervical intervertebral space. DSES increases as one moves caudally. The greatest DSES was noted at C7-T1 in men, and the least was at C5-6 in women. DSES had a significant relationship with weight, neck circumference, and body mass index in both genders.
