Randomized Controlled Trial Comparative Study
A comparison of motor stimulation threshold in ultrasound-guided interscalene brachial plexus block for arthroscopic shoulder surgery: a randomized trial.
As the use of ultrasound for regional anesthesia has increased, many studies have examined the distribution of local anesthetic and the location of the needle tip. Nevertheless, the relationship between motor stimulation threshold and distribution of local anesthetic is unclear. The aim of this study was to compare block onset time, distribution of local anesthetic, and location of the needle tip at two different motor stimulation thresholds, i.e., 0.2 and 0.5 mA, used in combination with ultrasound guidance. ⋯ The onset time of the block was significantly faster with a motor stimulation threshold of 0.2 mA than with a threshold of 0.5 mA.

Randomized Controlled Trial Comparative Study
Effects of changing from sevoflurane to desflurane on the recovery profile after sevoflurane induction: a randomized controlled study.
Desflurane has the lowest solubility of currently available volatile anesthetics and may allow for more rapid emergence and recovery compared with sevoflurane. Nevertheless, after volatile induction with sevoflurane, it has not been determined whether the use of desflurane provides faster emergence and recovery. The present study aimed to elucidate the effects of changing from sevoflurane to desflurane during the early part of anesthesia. ⋯ Changing the anesthetic agent from sevoflurane to desflurane after sevoflurane induction provides faster emergence and recovery compared with sevoflurane anesthesia.

Randomized Controlled Trial
Parecoxib sodium reduces the need for opioids after tonsillectomy in children: a double-blind placebo-controlled randomized clinical trial.
Postoperative pain is a common phenomenon after pediatric tonsillectomy. This prospective randomized double-blind placebo-controlled clinical trial was performed to evaluate the analgesic efficacy of intravenous parecoxib sodium in children undergoing tonsillectomy. ⋯ A single intravenous injection of parecoxib sodium 1 mg·kg(-1) after anesthesia induction is an effective method for the control of postoperative pain. It provides a morphine-sparing effect, prolongs the time to first rescue analgesic, and reduces PONV in children undergoing tonsillectomy.

Randomized Controlled Trial
Analgesic efficacy of preemptive pregabalin administration in arthroscopic shoulder surgery: a randomized controlled trial.
The purpose of the current study was to evaluate the effects of pregabalin administration as an adjunct to fentanyl-based intravenous patient-controlled analgesia on opioid consumption and postoperative pain following arthroscopic shoulder surgery. ⋯ A preoperative dose of pregabalin 150 mg administered before arthroscopic shoulder surgery resulted in significant analgesic efficacy for 48 hr in terms of opioid-sparing effect and improved pain intensity scores without influencing complications. This trial was registered at: http://cris.nih.go.kr , number CT0000578.

Randomized Controlled Trial
Thermal quantitative sensory testing to assess the sensory effects of three local anesthetic solutions in a randomized trial of interscalene blockade for shoulder surgery.
This study investigated whether quantitative sensory testing (QST) with thermal stimulations can quantitatively measure the characteristics of an ultrasound-guided interscalene brachial plexus block (US-ISB). ⋯ Quantitative sensory testing can be useful as a method for detecting the presence and characteristics of regional anesthesia-induced sensory block and may be used for the evaluation of clinical protocols. The three local anesthetic solutions exhibited a similar anesthetic effect. The results support the use of QST to assess block characteristics quantitatively under clinical research conditions. This trial was registered at Clinicaltrals.gov, NCT02271867.
