To assess the most appropriate postoperative analgesic technique after hip surgery. ⋯ After THA, i.v. PCA with morphine, continuous "3-in-1" block, and PCEA provided comparable pain relief. Because it induces the fewest technical problems and side effects, continuous "3-in-1" block is the preferred technique.

To determine whether using only previous cases' surgical times for predicting accurately surgical times of future cases is likely to reduce the average length of time cases finish late (after their scheduled finish times). ⋯ An OR manager considering using only historical surgical times to estimate future surgical times should first investigate, using data from their own surgical suite, what percentage of cases do not have historical data. Even if there are sufficient historical data to estimate future surgical times accurately, relying solely on historical times is probably an ineffective strategy to have future cases finish on time.

Randomized Controlled Trial Clinical Trial
Isoflurane, nitrous oxide, and fentanyl pharmacodynamic interactions in surgical patients as measured by effects on median power frequency.
To identify and quantify the simultaneous interactions of isoflurane, nitrous oxide (N2O), and fentanyl during surgical procedures. The slowing of the EEG to a median power frequency of 2 Hz to 3 Hz was chosen as the measure of pharmacodynamic drug effect. ⋯ The potency of N2O and fentanyl to substitute isoflurane in maintaining a median power frequency of 2 Hz to 3 Hz during surgery is less than anticipated from minimum alveolar concentration studies.

To examine whether the establishment of dedicated pediatric operating rooms (ORs) staffed exclusively by pediatric anesthesiologists has had a significant impact on anesthetic efficiency during surgery. ⋯ The establishment of dedicated pediatric ORs resulted in significantly shorter anesthesia induction and emergence times. Furthermore, the decreased variability of anesthesia-controlled time may allow for better scheduling of surgical cases and for better surgeon and patient satisfaction.

Case Reports
Entrapment of an exchange wire by an inferior vena caval filter: a technique for removal.
The anesthesiology literature does not describe entrapment of a guidewire by an inferior vena caval filter. Because anesthesiologists are involved in central access in various perioperative and intraoperative settings, consideration of this complication is important. A case of guidewire entrapment by an inferior vena caval filter and a unique technique for removal of the entrapped wire is presented.
