Anaesthesia

The Department of Anaesthesia and Intensive Care at the Chinese University of Hong Kong provides a 4 week course in our specialty for final year medical students. Our curriculum covers basic concepts in anaesthesia and intensive care, management of common medical emergencies and the safe performance of basic practical skills. ⋯ We believe that our adaptation of the Objective Structural Clinical Examination is better than traditional methods of examination and it has allowed us to identify deficiencies in our teaching methods. The Objective Structured Clinical Examination has been well received by our students and is perceived by them to be a fair reflection of their level of knowledge and skill attainment during the course.

Randomized Controlled Trial Comparative Study Clinical Trial
Premedication with midazolam in children. Effect of intranasal, rectal and oral routes on plasma midazolam concentrations.
We report a study performed to compare the time and plasma drug concentrations necessary to achieve a similar state of sedation after midazolam premedication given by various routes in children of 2-5 years old. Children were randomly allocated to one of three groups to receive midazolam 0.2 mg.kg-1 given intranasally, 0.5 mg.kg-1 given orally or 0.3 mg.kg-1 given rectally. Sedation was measured regularly until venepuncture was possible in a cooperative child. ⋯ Duration of surgical procedures, and of propofol infusion, and recovery from anaesthesia was similar for the three groups. The only problem arose in a 30-month-old boy in the intranasal group who developed respiratory depression with a plasma midazolam concentration of 169 ng.ml-1. Intranasal midazolam is an excellent alternative for rapid premedication provided that respiratory monitoring is used.

Consecutive obese (n = 53) and non-obese parturients (n = 609) were prospectively evaluated during labour to analyse the influence of maternal obesity on labour pain and outcome. Excessive pre-pregnancy weight was classified as a body mass index of 30 kg.m-2 or more. Pain intensity was measured using an 11 point visual scoring scale. ⋯ After delivery, obese women were significantly more content with the pain relief received; only 12% vs 23% in the control group complained of poor pain control (p = 0.03). In this study, obesity and increased fetal size did not complicate labour or its outcome. Critical patient assessment should be emphasised, however, due to the physiological and medical problems present in obese parturients.
