A beat-by-beat, on-line, cardiovascular index, CARDEAN, to assess circulatory responses to surgery: a randomized clinical trial during spine surgery.

Automated assessment of circulatory response to surgical stimuli is unsolved. Would detection of cardiac baroreflex inhibition assess adequacy of intra-operative anti-nociception upon incision, as performed on-line on a beat-by-beat basis by a cardiovascular index, CARDEAN™? 18 ASA I-II patients undergoing spinal disc repair were studied, in a prospective randomized single-blinded trial (observational study). During infusion of propofol to maintain bispectral index between 40 and 60, patients were allocated to receive an effect site target-controlled infusion of remifentanil at Ce = 2 or 4 ng ml(-1).

Do patients still require admission to an intensive care unit after elective craniotomy for brain surgery?

Background: After elective craniotomy for brain surgery, patients are usually admitted to an intensive care unit (ICU). We sought to identify predictors of postoperative complications to define perioperative conditions that would safely allow ICU bypass.

Methods: This observational cohort study enrolled 358 patients admitted to neuro-ICU after elective intracranial procedures.

Right ventricular function after coronary surgery with or without bypass.

Background And Objective: Myocardial protection during aortic clamp period may sometimes be inadequate, especially for the right. The aim of this study was to compare right ventricle function after cardiac surgery with or without bypass.

Methods: Patients undergoing multivessel coronary surgery with proximal severe right coronary lesion were included in a prospective observational cohort study including 29 patients undergoing coronary surgery with or without bypass.

[Continuous infusion of remifentanil and target-controlled infusion of propofol for coronary surgery in elderly patients: comparison with continuous infusion of remifentanil and propofol].

Objectives: Comparison of the length of mechanical ventilation and postoperative complications after coronary surgery in elderly patients anaesthetised with propofol associated with either alfentanil or remifentanil.

Study Design: Retrospective study with an historic control group.

Patients: Three hundred thirty-eight consecutive patients (75-year-old or more) undergoing isolated coronary surgery.
