Aspects of infection in intensive care unit--prevention and control.

Nosocomial infections are the main source of infection in a hospitalized patient. Source of contaminant may be multiple. In a cardiac ICU the vulnerable open heart surgery patients are with multiple invasive lines and monitors. Pediatrics and neonates are more vulnerable because of their poor immunity and nutritional debility. Frequent indwelling line access makes a patient more prone to systemic infection with variable organisms. Our aim is to minimize the chances of hospital acquired infection as far as possible by the use of systemic approach to the patients as guided by the international standard hospital protocol.
