Randomized Controlled TrialThe relative potencies for motor block after intrathecal ropivacaine, levobupivacaine, and bupivacaine.
In this study, we sought to determine the median effective dose (ED50) for motor block of intrathecal ropivacaine, levobupivacaine, and bupivacaine and to define their motor-blocking potency ratios. ⋯ There is a clinical profile of potency for motor block for the pipecolylxylidines when administered spinally: low, intermediate, and high for ropivacaine, levobupivacaine, and bupivacaine, respectively.

Randomized Controlled TrialQuality differences in postoperative sleep between propofol-remifentanil and sevoflurane anesthesia in infants.
Postoperative behavioral disorders are common in children, but the occurrence in infants is not yet clear. In the present study we focus on postoperative sleep disturbances, which we hypothesized would be more common after sevoflurane anesthesia than propofol-remifentanil anesthesia. ⋯ Postoperative sleep disturbances occur in infants after both propofol-remifentanil and sevoflurane anesthesia. Sevoflurane seems to be associated with less impairment of postoperative sleep than propofol-remifentanil in the first weeks after repair of cleft lip and palate in infants.

Multicenter Study Comparative StudyFive-year follow-up on the work force and finances of United States anesthesiology training programs: 2000 to 2005.
In the middle 1990s, there was a decrease in anesthesiology residency class sizes, which contributed to a nationwide shortage of anesthesiologists, resulting in a competitive market with increased salary demands. In 1999, a nationwide survey of the financial status of United States anesthesiology training programs was conducted. Follow-up surveys have been conducted each year thereafter. We present the results of the sixth survey in this series. ⋯ These results demonstrate the continuing need for institutional support to keep anesthesiology training departments financially stable.

Randomized Controlled TrialThe effects of arm position on onset and duration of axillary brachial plexus block.
We assessed the effects of arm position after block performance on success rate, onset time, and duration of axillary block (AXB). ⋯ Maintaining the arm in abduction after performing AXB allows a shorter onset time and a prolongation of the sensory and motor blocks.

Randomized Controlled TrialThe effect of intravenous administration of dexamethasone on postoperative pain, nausea, and vomiting after intrathecal injection of meperidine.
Different drugs have been used to enhance postoperative neuraxial opioid analgesia and reduce adverse effects. ⋯ Administration of IV dexamethasone prior to intrathecal meperidine injection enhances analgesia and reduces PONV.
