🦠 PEDIATRIC INFECTIOUS DISEASES – DETAILED NOTES (NORCET LEVEL PDF)

📌 **INTRODUCTION

Children are more susceptible to infections due to:

* Immature immune system
* Poor hygiene practices
* Incomplete vaccination
* Close contact in schools/daycare

Pediatric infectious diseases are a major cause of morbidity & mortality in children, especially under 5 years.

🛡 IMMUNITY IN CHILDREN (IMPORTANT BASE)

* Passive immunity: From mother (IgG via placenta, IgA via breast milk)
* Active immunity: Through vaccination & infections
* Neonates have low IgM & IgA
* Full immune maturity achieved by 5–7 years

🏵️Insulin helps move glucose from the blood into the body’s cells where it’s used for energy.

When we eat carbs, they’re broken down into glucose, this glucse enters the bloodstream causing hyperglycaemia, the pancreas releases insulin in response.

How insulin works:
1. After eating, blood glucose levels rise
2. Pancreas detects the rise and secretes insulin
3. Insulin binds to insulin receptors on cell membranes (especially in muscles, liver, and fat cells)
4. This opens glucose channels, allowing glucose to enter the cells
5. Blood glucose levels return to normal

Think of insulin as the “key” which unlocks cells to let sugar in

Insulin tidbits:
- Always check timing in relation to meals
- Know hypo symptoms
- Rotate injection sites to prevent lipohypotrophy
- Double-check insulin and dose
- Be aware of “sick day” rules - insulin may still be needed even if not eating

CATHETER-ASSOCIATED URINARY TRACT INFECTION (CAUTI) — COMPLETE NURSING NOTES

CAUTI is one of the most common hospital-acquired infections (HAIs) and a guaranteed MCQ topic for nursing exams.
📌 DEFINITION (Exam Ready)

CAUTI is a urinary tract infection that occurs in a patient who has an indwelling urinary catheter in place for more than 48 hours.

📍 MCQ Tip:
UTI + catheter ≥ 48 hours → CAUTI

📌 COMMON CAUSATIVE ORGANISMS

• Escherichia coli (most common)
• Klebsiella
• Pseudomonas
• Enterococcus
• Proteus

📍 Most common organism → E. coli

📌 RISK FACTORS

• Prolonged catheterization
• Break in aseptic technique
• Female gender
• Diabetes mellitus
• Poor perineal hygiene
• Advanced age

📌 PATHOPHYSIOLOGY

• Catheter bypasses natural defense
• Microorganisms ascend along catheter
• Biofilm formation occurs
• Leads to infection of urinary tract

📍 Biofilm = bacteria protection layer

📌 CLINICAL FEATURES

• Fever
• Dysuria
• Suprapubic pain
• Cloudy, foul-smelling urine
• Hematuria
• Altered sensorium (elderly)

📌 DIAGNOSIS

• Urine routine & microscopy
• Urine culture
• Elevated WBC count

📍 Significant bacteriuria → ≥10⁵ CFU/ml

CAUTI PREVENTION BUNDLE

1️⃣ Hand hygiene before & after handling catheter
2️⃣ Use aseptic technique during insertion
3️⃣ Maintain closed drainage system
4️⃣ Keep urine bag below bladder level
5️⃣ Avoid unnecessary catheterization
6️⃣ Daily catheter care
7️⃣ Remove catheter as early as possible

📍 MCQ: Best prevention → Early catheter removal

🩺 NURSING MANAGEMENT

• Monitor urine output & characteristics
• Maintain catheter patency
• Encourage oral fluids
• Perineal care daily
• Monitor for signs of infection
• Educate patient

📌 COMPLICATIONS

• Pyelonephritis
• Urosepsis
• Prolonged hospital stay

📌 EXAM PEARLS

• CAUTI occurs after → 48 hours
• Most common organism → E. coli
• Best prevention → Remove catheter early
• Urine bag should be → Below bladder level

📌 QUICK MCQs

1. CAUTI comes under → HAIs
2. Biofilm formation seen in → Catheter infections
3. Significant bacteriuria value → 10⁵ CFU/ml
4. Most effective prevention → Early remove
