Anaesthesia

We report our experience in introducing patient-controlled analgesia at the Royal Hospital for Sick Children, Glasgow. Twenty-five children used the technique after orthopaedic or general surgery using the Graseby system. The pump was loaded with 1 mg/kg morphine sulphate in 50 ml. ⋯ Adverse effects were few and minor. Education of patients, parents and nurses is essential for its success and safety. The technique is an effective and safe means of providing good quality analgesia in school age children.

The laryngoscopic conditions of 62 diabetic patients who underwent renal transplantation or vitrectomy were studied. Anaesthesia was induced with fentanyl and a sleep dose of thiopentone. Conditions for direct laryngoscopy after 0.1 mg/kg vecuronium were scored from 0 to 3 (easy-very difficult). ⋯ The correlation coefficient between these two factors was r = 0.6 (p less than 0.001). Our study shows that joint rigidity possibly caused by tissue glycosylation may also involve laryngeal and cervical areas resulting in a strenuous laryngoscopy. A defective palm print is a warning sign for difficult laryngoscopy.

The Ohmeda 9000 syringe pump was developed in response to the need for an infusion apparatus to administer intravenous anaesthetic agents. It incorporates a bolus facility for the rapid, controlled delivery of loading infusions, or incremental dosing over a background maintenance infusion, and may be interfaced with a controller for computer-driven infusions. ⋯ The pump was easy to use and reliable in clinical research and routine clinical practice. It should find its niche as the first genuinely 'anaesthetist-friendly' infusion pump.
