AIM: This was a randomized single blinded study to determine optimal size for Ambu®LMA (ALMA) among Malaysian adult population.
METHODS: One hundred and twenty six non-paralyzed anaesthetized adult patients were block randomized into size 3, 4 and 5 Ambu®LMA. Optimal size is defined primarily by oropharyngeal pressure (OLP). Pharyngeal injury and ease of insertion are also taken into consideration.
RESULTS: Mean OLP was significantly higher for Size 4 and 5 compared to size 3 (p<0.001) but similar between size 4 and 5. Number of insertion attempts and insertion time were similar between sizes. Size 5 required more manipulations during insertion (p<0.005) and had higher pharyngeal injury (p=0.001) compared to size 3 and 4.
DISCUSSION: We recommend size 4 ALMA as the optimal size for Malaysian adults in view of the higher OLP compared to size 3, yet less pharyngeal injury than size 5 in spontaneously breathing patients.
From April 1992 to September 1992, 280 samples of 10 different fresh vegetables, bought from four different market outlets in Kuala Lumpur were examined for the presence of Listeria spp. Most of the market produce were locally grown with the exception of carrots. The isolation procedure was based on the Food & Drug Administration method (modified) used for the detection of Listeria spp. Isolation media used were Listeria Selective medium and LiCl- phenylethanol-Moxalactam agars. The identification of isolates was by means of conventional biochemical tests and API Listeria identification system. Five out of the 280 samples showed Listeria contamination, Listeria monocytogenes was isolated in lettuce, sengkuang (Pachyrrhizus erosus) and selom Oenanthe javanica) and Listeria innocua was isolated from sengkuang (Pachyrrhizus erosus) and pegaga (Hydrocotyle asiatica).
