BACKGROUND: The summary of various studies done looking at size selection of the laryngeal mask airway (LMA) in adults is that, selection based on sex is appropriate, and that both sizes 4 or 5 are adequate for adult females. However, in our local population these sizes may be too large especially the size 5 for adult females. OBJECTIVE: To determine the optimal size of LMA in Malaysian female adults. METHOD: 135 ASA 1 or 2 adult female patients coming for elective surgery, requiring general anaesthesia suitable for LMA insertion were randomised into 3 groups to receive either a size 3, 4 or 5 LMA. Optimal size of the LMA was assessed based on 4 parameters, the number of attempts at placement, the oropharyngeal leak pressure (OLP), fibre optic score and the percentage of the vocal cords seen. RESULTS: The 3 groups were demographically similar. There was no difference in the 3 groups in terms of number of attempts of placement, OLP and fibre-optic score. The percentage of vocal cords seen with the size 3 LMA was significantly less than for the size 4 and size 5 (p = 0.009). For the size 5 LMA group in 10/45 patients, the size 5 LMA was too big making it incorrectly positioned after successful insertion and in another 3/45 patients it was difficult to pass the size 5 LMA past the open mouth during insertion. There were no such problems with the size 3 or 4 LMA groups. CONCLUSION: The optimal size of LMA for the female Malaysian adult is size 4.

Purpose: There are relatively few student-led medical conferences worldwide. A group of medical and nursing students from Yong Loo Lin School of Medicine, National University of Singapore, organized an annual student-led faculty-supported inter-professional Student Medical-Nursing Education Conference (SMEC), which consisted of plenary talks, lectures and workshops, and a scientific competition. This research focused on the evaluation of workshops conducted during the 8th SMEC 2012. Method: The authors used various process variables to survey the conference participants on the educational value of the 4 plenary lectures and 20 workshops, half of which were run by experienced healthcare professionals and the other half by current seniors or recent graduates. Results: A total of 270 medical and nursing students completed the survey. Good to excellent educational value was reported for most of the workshops. Higher educational value was associated with use of props (correlation coefficient, r=0.733 and 0.568), adherence to workshop topic/focus (r=0.608 and 0.815) and openness of presenter to questions (r=0.555 and 0.453). Conclusion: A student-led, faculty-supported interprofessional conference organized by medical and nursing students had good to excellent self-reported education value in helping their fellow medical and nursing students learn about various healthcare disciplines and prepare for medical and nursing school.
