Abstract

|
Postoperative infection has been important in management of operating room nursing care and has been found to be related with airborne microbes during operation: This study was conducted to identify the correlation of times and contamination level in operative instrument table at 200-beds hospital from 10th December to 14th December, 1990.
Airborne microbes were collected from 42 blood agar plates. Airborne microbes were cultured and counted according to R. Koch s method for quantitative sampling of airborne microbes during operation.
As a result of this study, the following conclusions were obtained.
1. Air sampling was done by exposing standard petridish (Blood Agar) for more than 20 minutes.
Colonies were 15.3 for 20min, 19.2 for 30min, 31.6 for 40min, 38.3 for 60min, 47.0 for 80min48.0 for 110min, 56.6 for 120min, 60.0 for 150min, 67.6 for 180min, 71.6 for 210min, 78.3 for 240min and 92.0 for 270min.
2. The more times passed at operating room, the more the operative instrument table was contaminated(r=+0.317, df=42, p<0.05).
