Case ReportsThe use of "ketofol" (ketamine-propofol admixture) infusion in conjunction with regional anaesthesia.
We present four patients in whom a "ketofol" (ketamine 200 mg and propofol 200 mg) infusion was used in conjunction with regional anaesthesia. The patients were considered 'high risk' due to their medical condition or age. The ketofol proved safe and effective in all four cases. Advantages of this technique included analgesia, airway preservation, maintenance of spontaneous respiration, haemodynamic stability and rapid recovery.

Multicenter StudyDrug administration errors: a prospective survey from three South African teaching hospitals.
This prospective study was undertaken to determine the incidence of drug administration errors by anaesthetists at three tertiary South African hospitals. Hospitals A and C treat adults predominantly, whereas Hospital B is a paediatric hospital. Anaesthetists completed an anonymous study form for every anaesthetic performed over a six-month period. ⋯ No major complication attributable to a drug administration error was reported. Despite an increasing awareness of the problem together with suggestions in the literature to reduce the incidence, drug administration errors remain fairly common in South Africa. Failure to institute suggested solutions will continue to compromise patient safety.

Randomized Controlled Trial Comparative StudyRandomised comparison of the Classic Laryngeal Mask Airway with the Cobra Perilaryngeal Airway during anaesthesia in spontaneously breathing adult patients.
We tested the hypothesis that the Cobra Perilaryngeal Airway (PLA) with its high volume low-pressure cuff would provide superior airway leakage pressure compared with the Classic Laryngeal Mask Airway (LMA) in spontaneously breathing adult patients. Ninety consecutive adult patients were randomly allocated to receive one of these two supralaryngeal devices. The airway leakage pressure was higher for the PLA compared with the LMA (22 +/- 9 cmH2O vs. 18 +/- 6 cmH2O; P < 0.05). ⋯ The number of attempts required to achieve successful insertion and the incidence of postoperative complications were similar in both groups. The findings suggest that the PLA provides a superior airway seal at a lower intracuff pressure compared to the LMA. However the time for successful insertion may be increased.
