Randomized Controlled Trial Multicenter Study
Randomized placebo-controlled study evaluating lateral branch radiofrequency denervation for sacroiliac joint pain.
Sacroiliac joint pain is a challenging condition accounting for approximately 20% of cases of chronic low back pain. Currently, there are no effective long-term treatment options for sacroiliac joint pain. ⋯ These results provide preliminary evidence that L4 and L5 primary dorsal rami and S1-S3 lateral branch radiofrequency denervation may provide intermediate-term pain relief and functional benefit in selected patients with suspected sacroiliac joint pain. Larger studies are needed to confirm these results and to determine the optimal candidates and treatment parameters for this poorly understood disorder.

Review Meta Analysis
Greater incidence of emergence agitation in children after sevoflurane anesthesia as compared with halothane: a meta-analysis of randomized controlled trials.
Sevoflurane is a popular inhalational anesthetic for general anesthesia in children. The higher incidence of emergence agitation has been suspected after sevoflurane anesthesia as compared with halothane, whereas some controlled studies showed conflicting results. In this report, the authors performed a meta-analysis of randomized controlled trials to compare the incidence of emergence agitation in children after sevoflurane or halothane anesthesia. ⋯ This meta-analysis revealed that emergence agitation occurred more frequently with sevoflurane than with halothane anesthesia in children.

Randomized Controlled Trial Multicenter Study
Reversal of profound, high-dose rocuronium-induced neuromuscular blockade by sugammadex at two different time points: an international, multicenter, randomized, dose-finding, safety assessor-blinded, phase II trial.
Sugammadex (Org 25969), a novel, selective relaxant binding agent, was specifically designed to rapidly reverse rocuronium-induced neuromuscular blockade. The efficacy and safety of sugammadex for the reversal of profound, high-dose rocuronium-induced neuromuscular blockade was evaluated. ⋯ Sugammadex provides a rapid and dose-dependent reversal of profound neuromuscular blockade induced by high-dose rocuronium (1.0 or 1.2 mg/kg) in adult surgical patients.

Randomized Controlled Trial
Droperidol and ondansetron-induced QT interval prolongation: a clinical drug interaction study.
Droperidol and ondansetron have previously been found to prolong the QT interval in the treatment of postoperative nausea and vomiting. However, this adverse effect has never been confirmed and compared with both drugs under controlled conditions. The objective was to study the effects of droperidol and ondansetron alone or in combination on QT interval duration in healthy subjects. ⋯ Under controlled conditions, both droperidol and ondansetron either alone or in combination induced significant marked QTc interval prolongation. However, the combination of both drugs did not significantly increase QTc prolongation compared with that induced by droperidol alone.

Most clinically available thermometers accurately report the temperature of whatever tissue is being measured. The difficulty is that no reliably core-temperature-measuring sites are completely noninvasive and easy to use-especially in patients not undergoing general anesthesia. Nonetheless, temperature can be reliably measured in most patients. ⋯ Anesthetic-induced impairment of normal thermoregulatory control, with the resulting core-to-peripheral redistribution of body heat, is the primary cause of hypothermia in most patients. Neuraxial anesthesia also impairs thermoregulatory control, although to a lesser extent than does general anesthesia. Prolonged epidural analgesia is associated with hyperthermia whose cause remains unknown.
