[Reporting of muscle relaxant effects in anaesthesia files concerning visceral surgery - a observational and multicenter study].

Objectives: To report any item documenting the peroperative muscle relaxant effects management in anaesthesia files issued from visceral surgery processes.

Type Of Study: Prospective, observational and multicenter.

Patients And Methods: A single operator analysed 1453 files proposed by nine anaesthetists' teams.

[Anaesthetic preoperative assessment of chronic medications and herbal medicine use: a multicenter survey].

Objective: This study was undertaken to quantify the use of chronic medication and herbal remedies in the presurgical population.

Study Design: Prospective multicenter survey.

Patients And Methods: Adult patients presenting for anaesthesia were directly asked if they were currently using chronic medication or herbal remedies.

Postoperative residual neuromuscular block: a survey of management.

Background: To avoid postoperative residual neuromuscular block there is a need for a change in clinician's attitude towards monitoring and reversal. This study aims to evaluate changes of perioperative neuromuscular block management during the last decade in our institution and to quantify the incidence of postoperative residual neuromuscular block.

Methods: Patients receiving intermediate-acting neuromuscular blocking agents for scheduled surgical procedures during 3-month periods in 1995 (n=435), 2000 (n=130), 2002 (n=101), and in 2004 (n=218) were prospectively and successively enrolled in our study.

Residual curarization in the recovery room after vecuronium.

We have investigated residual block after anaesthesia which included the use of the neuromuscular blocking agent vecuronium but no anticholinesterase, in 568 consecutive patients on admission to the recovery room. The ulnar nerve was stimulated submaximally using TOF stimulation (30 mA). Postoperative residual curarization was defined as a TOF ratio < 0.

Optimal dose of lignocaine for preventing pain on injection of propofol.

The purpose of this study was to define the optimum dose of lignocaine required to reduce pain on injection of propofol. We conducted a prospective, randomized, double-blind trial on 310 patients undergoing anaesthesia. Patients were allocated to four groups according to the lignocaine dosage: group A (control), no lignocaine; group B, lignocaine 0.

[A nicardipine-isoflurane combination in the microsurgery of the middle ear].

Middle ear microsurgery requires a bloodless operative field, achieved through deliberate hypotension techniques. The present work was designed to analyze the quality of the deliberate hypotension induced by the combination of isoflurane with nicardipine, an injectable calcium channel blocker. Eleven patients, ASA I, 10 minutes after induction of anaesthesia, received nicardipine as a bolus of 25 mg renewed every five minutes (maximum 4) and as a perfusion (5 mg/hour).
