Randomized Controlled TrialModified 45-degree head-up tilt increases success rate of lumbar puncture in patients undergoing spinal anesthesia.
Lumbar puncture (LP) is one of the most common procedures performed in medicine. The aim of this prospective study is to determine the success rate of LP in lateral decubitus with 45-degree head-up tilt position, and compare it with traditional positions like sitting and lateral decubitus. ⋯ The lateral decubitus in knee-chest position with a 45-degree head-up tilt may be the preferred position for spinal anesthesia in young and elderly patients, due to the high success rate.

Randomized Controlled TrialDifferential axillary nerve block for hand or forearm soft-tissue surgery.
This study determined the effective concentration of ropivacaine required to produce the type of differential block known as sensory block with mobilization, for adequate analgesia after forearm or hand soft tissue surgery by axillary brachial plexus block. ⋯ This analysis showed that 16 ml of 0.1285 % ropivacaine is suitable for achieving differential block in ultrasound-guided axillary nerve block for hand and forearm surgery.

Randomized Controlled TrialLateral Trendelenburg with the injected side down after the block improves the efficacy of the axillary approach to brachial plexus block.
We hypothesized that, after axillary block, positioning the patient in a lateral position with the injected side down and simultaneously in a 20° Trendelenburg position will increase the success rate and quality of the block. ⋯ We conclude that, for patients undergoing an axillary block, positioning the patient laterally with the injected side down and in a 20° Trendelenburg position increases the success rate and quality of the block.

Randomized Controlled Trial Comparative StudyUltrasound-guided sciatic nerve block: a comparison between four different infragluteal probe and needle alignment approaches.
Our aim was compare onset time of sciatic nerve blockade (SNB) performed distal to the subgluteal fold using four different ultrasound (US)-guided approaches in patients undergoing foot or ankle surgery. ⋯ The LA-IP approach resulted in a rapid onset of SNB and was associated with the best satisfaction for postoperative analgesia in comparison with LA-OP, SA-IP, and SA-OP approaches for patients undergoing foot and ankle surgery.

Randomized Controlled TrialMethadone patient-controlled analgesia for postoperative pain: a randomized, controlled, double-blind study.
Postoperative pain is an important health-care issue. Patient-controlled analgesia (PCA) is considered the gold standard for systemic postoperative pain treatment. Methadone PCA is used for patients with chronic pain and those in the palliative care setting. However, its efficacy as a first-line drug for acute postoperative pain is unknown. This study evaluated the use of postoperative methadone PCA after total hip arthroplasty (THA) compared with morphine PCA. ⋯ This study demonstrated that methadone PCA prompted less opioid consumption and lower pain scores at rest and at motion in comparison with morphine PCA as postoperative analgesia after THA.
