Anaesthesia
-
Awake fibreoptic intubation is well established as the optimum method of securing the airway in patients in whom difficulty is anticipated. We report a patient undergoing awake fibreoptic intubation in whom the use of topical local anaesthetic precipitated acute loss of the airway so that urgent surgical intervention was required.

Epidural abscess is a well-recognised but rare complication of epidural catheter placement. We have found only five previous reports of epidural abscess from noncatheter-related administration of steroids and/or local anaesthetic. We describe a further case which led to critical illness and emphasise the association between diabetes mellitus and epidural infection.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol anaesthesia and vomiting after myringoplasty in children.
To determine whether propofol anaesthesia reduces the incidence of nausea and vomiting after ear surgery, 40 children aged 4-16 years were randomly assigned to receive either propofol or inhalational anaesthesia. Children in the propofol group had anaesthesia induced with propofol and maintained with propofol-nitrous oxide and those in the inhalational group had anaesthesia induced with thiopentone and maintained with isoflurane-nitrous oxide. Nausea and vomiting were recorded for 24 h after surgery and metoclopramide was offered to children who vomited more than twice. ⋯ The incidence of vomiting was lower in the propofol group during the first 2 h after surgery (0% and 25% propofol and inhalational groups, respectively) (p < 0.05) but was similar at all other time intervals. Rescue anti-emetic was given to two (10%) and eight (40%) children in the propofol and inhalational groups, respectively (p < 0.05). We conclude that propofol anaesthesia alone is not an effective means of preventing vomiting after middle ear surgery in children.

Randomized Controlled Trial Clinical Trial
Laryngeal mask lubrication. A comparative study of saline versus 2% lignocaine gel with cuff pressure control.
We compared 2% lignocaine gel with saline as a lubricant for the laryngeal mask airway in 126 patients receiving positive pressure ventilation in whom cuff pressures were limited to 60 cmH2O and peak airway pressures to less than 17 cmH2O. The incidence of sore throat was similar for both groups and there were no emergence problems. ⋯ Lignocaine gel is an unsuitable lubricant for the laryngeal mask airway. Cuff pressure limitation to 60 cmH2O does not necessarily impede ventilation and may be an important factor in reducing emergence and postoperative complications.
