Randomized Controlled Trial
Glycopyrrolate during sevoflurane-remifentanil-based anaesthesia for cardiac catheterization of children with congenital heart disease.
Remifentanil is recommended for use in procedures with painful intraoperative stimuli but minimal postoperative pain. However, bradycardia and hypotension are known side-effects. We evaluated haemodynamic effects of i.v. glycopyrrolate during remifentanil-sevoflurane anaesthesia for cardiac catheterization of children with congenital heart disease. ⋯ I.V. glycopyrrolate 6 microg kg(-1) prevents bradycardia during general anaesthesia with remifentanil and sevoflurane for cardiac catheterization in children with congenital heart disease. Administering 12 microg kg(-1) of glycopyrrolate temporarily induces tachycardia and offers no additional advantage.

Randomized Controlled Trial Comparative Study
Intubating laryngeal mask for airway management in lateral decubitus state: comparative study of right and left lateral positions.
The intubating laryngeal mask has been used for the emergency management of the airway in patients placed in the lateral decubitus position. We have conducted this prospective study to compare the feasibility of placement of an intubating laryngeal mask and blind tracheal intubation guided by the intubating laryngeal mask in patients placed in the right and the left lateral positions. ⋯ Insertion of the intubating laryngeal mask and blind tracheal intubation through it in the lateral position is feasible in patients with normal airways. These procedures have a high and comparable success rate when patients are placed in the right and left lateral positions.

This review examines the evidence from published data concerning the tolerability (indicated by the incidence of nausea, vomiting, sedation, pruritus, and urinary retention), of three analgesic techniques after major surgery; intramuscular analgesia (i.m.), patient-controlled analgesia (PCA), and epidural analgesia. A MEDLINE search of publications concerned with the management of postoperative pain and these indicators identified over 800 original papers and reviews. Of these, data were extracted from 183 studies relating to postoperative nausea and vomiting, 89 relating to sedation, 166 relating to pruritus, and 94 relating to urinary retention, giving pooled data which represent a total of more than 100,000 patients. ⋯ The incidence of nausea and excessive sedation decreased over the period 1980-99, but the incidence of vomiting, pruritus, and urinary retention did not. From these published data it is possible to set standards of care after major surgery for nausea 25%, vomiting 20%, minor sedation 24%, excessive sedation 2.6%, pruritus 14.7%, and urinary retention requiring catheterization 23%. Acute Pain Services should aim for incidences less than this standard of care.

Randomized Controlled Trial
Tracheal intubating conditions and apnoea time after small-dose succinylcholine are not modified by the choice of induction agent.
In a randomized, double-blind clinical trial, we studied the effect of different i.v. induction drugs on tracheal intubation conditions and apnoea time after small-dose (0.6 mg kg(-1)) succinylcholine used to facilitate orotracheal intubation at an urban, university-affiliated community medical centre. ⋯ The use of succinylcholine 0.6 mg kg(-1) produced the same favourable intubation conditions and a short apnoea time regardless of the induction drug used.

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. ⋯ During the last decade the incidence of residual neuromuscular block strongly decreased in our institution. It confirms the positive impact of neuromuscular monitoring and reversal of neuromuscular block in routine anaesthetic practice.
