Infection control | NTNL Academy|

Welcome to NTNL Academy! In today’s comprehensive lecture, we dive deep into Nosocomial Infections, also universally known as Healthcare-Associated Infections (HAIs). Whether you are preparing for nursing exams, medical entrance tests, or your university microbiology finals, this video breaks down everything you need to know about how these infections develop, spread, and can be prevented. Nosocomial infections are defined as infections that patients acquire during the course of receiving healthcare treatment—typically manifesting 48 to 72 hours after hospital admission—which were neither present nor incubating at the time of admission. 📖 What You Will Learn in This Video: • Definition & Overview: Understanding HAIs and why the Intensive Care Unit (ICU) carries the highest risk. • Primary Causes & Pathogens: A look at the key microbes involved, including Gram-negative bacteria (Pseudomonas aeruginosa, E. coli) and Gram-positive bacteria (Staphylococcus aureus). • Top 5 Common Types of Nosocomial Infections: 1. Urinary Tract Infections (UTIs / CAUTI from indwelling catheters) 2. Surgical Site Infections (SSIs) 3. Nosocomial Pneumonia (including Ventilator-Associated Pneumonia / VAP) 4. Vascular Catheter / Bloodstream Infections (Septicemia) 5. Gastrointestinal Infections (like Clostridioides difficile) • Risk Factors: Host immunity, prolonged use of invasive medical devices, and antibiotic resistance. • Prevention & Control Strategies: The 5i moments of hand hygiene, Standard vs. Transmission-based precautions (PPE), sterilization techniques, and the critical role of the Hospital Infection Control Committee (HICC). #NosocomialInfection #HospitalAcquiredInfection #Microbiology #NursingLectures #NTNLAcademy #MedicalEducation #InfectionControl #HAIs #NursingExamPrep
