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.

Randomized Controlled TrialPlasma ropivacaine concentrations after ultrasound-guided transversus abdominis plane block for open retropubic prostatectomy.
Ropivacaine-induced vasoconstriction may affect the early absorption speed of ropivacaine; however, the effects of dose on pharmacokinetics following transversus abdominis plane (TAP) block have not been studied. In this study, we have examined plasma ropivacaine concentrations following TAP block with various ropivacaine concentrations (0.25, 0.5, and 0.75 %). ⋯ Ropivacaine concentration did not alter pharmacokinetic profile following TAP blocks.

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 StudyComparison of Siccoral(®) spray, Stomatovis (®) gargle, and Strefen (®) lozenges on postoperative sore throat.
Postoperative sore throat (POST) is a frequent complication caused by mucosal trauma to the pharyngeal, laryngeal, and tracheal airway after endotracheal intubation. We compared the effectiveness of Siccoral, Strefen, and Stomatovis treatments in alleviating POST. ⋯ Siccoral and Strefen can be effective in relieving POST in the early hours after extubation.
