DIGESTIVE SYSTEM

Abstract

Medical sterilization and infection control constitute the core foundation of safe medical practice and patient protection. In modern healthcare systems, the risks associated with microbial contamination, cross-infection, and hospital-acquired infections (HAIs) remain among the most significant global health challenges. Sterilization aims at the complete destruction of microorganisms, including highly resistant bacterial spores, viruses, fungi, protozoa, and prions. Infection control, in turn, is a broad, systematic approach that involves hygiene discipline, environmental sanitation, aseptic protocols, proper use of personal protective equipment, safe waste disposal, ventilation systems, antibiotic stewardship, outbreak management, and continual monitoring programs. As patient volume, surgical procedures, and invasive diagnostic interventions increase worldwide, the need for strict sterilization procedures becomes more critical. The growing threat of antimicrobial resistance adds further urgency to improving sterilization technologies and adherence to infection control protocols. Modern sterilization includes autoclaving, dry heat, ethylene oxide gas sterilization, hydrogen peroxide plasma sterilization, ozone sterilization, peracetic acid processing, and gamma irradiation. Infection control encompasses hand hygiene, PPE, surface disinfection, isolation precautions, environmental microbiological surveillance, and high-level reprocessing systems.
