Randomized Controlled Trial
Modified right-sided Broncho-Cath double lumen tube improves endobronchial positioning: a randomized study.
A left-sided double lumen tube is recommended for one-lung ventilation for most thoracic surgeries, but for certain indications, a right-sided double lumen tube (R-DLT) may be mandatory. Frequent malposition of R-DLTs has been reported. We propose an innovative modification of Mallinckrodt's Broncho-Cath R-DLT consisting of an enlarged area of the lateral orifice, and studied the impact of this modification on the adequacy of R-DLT positioning. ⋯ These data suggest the superiority of the modified Broncho-Cath R-DLT compared to a standard Broncho-Cath R-DLT for optimal R-DLT positioning to facilitate one-lung ventilation during thoracic surgery.

Randomized Controlled Trial
Influence of injection rate of hyperbaric bupivacaine on spinal block in parturients: a randomized trial.
A prospective, randomized, double-blind clinical trial was undertaken to determine whether a tenfold difference in the rate of intrathecal injection of bupivacaine would affect sensory block level in parturients. Secondary outcomes included onset of block and the incidence of hypotension and nausea. ⋯ Rapid intrathecal injection of hyperbaric bupivacaine does not affect spread of spinal anesthesia or the incidence of hypotension and nausea in parturients.

Randomized Controlled Trial Comparative Study
Early oral analgesia after fast-track cardiac anesthesia.
Oral analgesia after "fast-track" cardiac anesthesia has not been explored. The aim of this study was to compare two oral oxycodone analgesic regimens. ⋯ Peroral oxycodone is effective for early pain control after fast-track cardiac anesthesia. Immediate-release oxycodone/ acetaminophen appears to provide better analgesia and fewer side effects compared to controlled-release oxycodone.

Randomized Controlled Trial Comparative Study
Minimum effective anesthetic concentration (MEAC) for sciatic nerve block: subgluteus and popliteal approaches.
We tested the hypothesis that using a subgluteus approach to the sciatic nerve requires a lower concentration of mepivacaine to obtain complete anesthesia as compared with the popliteal approach. ⋯ A subgluteus approach to the sciatic nerve facilitates a reduction of the minimum effective concentration of local anesthetic required to produce an effective surgical block within 30 min after the injection as compared with the posterior popliteal approach.
