Impact of deep hypothermic circulatory arrest on the BIS index.

Study Objective: To investigate the influence of duration of deep hypothermic circulatory arrest (DHCA) on recovery of the bispectral index (BIS).

Design: Prospective cohort study.

Setting: Operating room of university teaching hospital.

Thoracic but not lumbar epidural anaesthesia increases liver blood flow after major abdominal surgery.

Background And Objective: Epidural blockade in major abdominal surgery bears the potential to increase gastrointestinal perfusion and thus to improve patient outcome. The aim of this study was to assess the differential influence of thoracic and lumbar epidural anaesthesia and analgesia (EAA) on blood lactate levels and central venous oxygen saturation (ScvO2) as parameters of global oxygen supply/demand ratio, as well as on the plasma disappearance rate of indocyanine green (PDR(ICG)), a noninvasive method to evaluate liver perfusion.

Methods: We enrolled 17 patients receiving thoracic and 17 patients receiving lumbar EAA in addition to general anaesthesia for major abdominal surgery.

Airway injuries after one-lung ventilation: a comparison between double-lumen tube and endobronchial blocker: a randomized, prospective, controlled trial.

Background: Vocal cord injuries, postoperative hoarseness, and sore throat are common complications after general anesthesia. One-lung ventilation can be achieved via two techniques: double-lumen endotracheal tube or endobronchial blocker such as the Arndt blocker. The current study was designed to assess the impact of these techniques for one-lung ventilation on the incidence and severity of postoperative hoarseness, vocal cord lesions, and sore throat.

A-line, bispectral index, and estimated effect-site concentrations: a prediction of clinical end-points of anesthesia.

Autoregressive modeling with exogenous input of middle-latency auditory evoked potentials (A-Line AEP index, AAI) has been developed for monitoring depth of anesthesia. We investigated the prediction of recovery and dose-response relationship of desflurane and AAI or bispectral index (BIS) values. Twenty adult men scheduled for radical prostatectomy were recruited.

Postoperative myalgia after succinylcholine: no evidence for an inflammatory origin.

Unlabelled: A common side effect associated with succinylcholine is postoperative myalgia. The pathogenesis of this myalgia is still unclear; inflammation has been suggested but without convincing evidence. We designed the present study to investigate whether an inflammatory reaction contributes to this myalgia.
