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. This study protocol was registered at http://www.umin.ac.jp/ctr/index.htm , (UMIN000009941).

Observational Study
The impact of blood pressure cuff location on the accuracy of noninvasive blood pressure measurements in obese patients: an observational study.
Obesity presents many challenges to the anesthesiologist, including poorly fitting blood pressure (BP) cuffs due to the conical shape of the upper arm. The aim of this study was to determine the accuracy of noninvasive BP readings, obtained from a noninvasive BP cuff using various cuff locations and wrapping techniques, compared with invasive intra-arterial BP readings. ⋯ All the forms of NIBP cuff orientation studied had unacceptable precision and bias compared with invasive ABP measurements. When patient and/or surgical conditions necessitate accurate BP monitoring, direct arterial measurement should be considered over NIBP measurements in obese patients.

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.
