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
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.
