PEDI | Infection + SEPSIS

Critical Bacterial & Toxin-Mediated InfectionsThe most clinically significant bacterial infections require immediate recognition of airway compromise and strict adherence to antibiotic regimens.• Airway & Neurological Risks: ◦ Diphtheria: Caused by Corynebacterium diphtheriae, this presents with a "bull’s neck" (edema) and a pseudomembrane over the pharynx that can cause airway obstruction. Treatment involves antitoxins and antibiotics. ◦ Pertussis (Whooping Cough): Characterized by paroxysmal coughing and copious secretions, requiring careful airway management. ◦ Tetanus: Manifests as jaw cramping (lockjaw) and spasms. Prevention via immunization and wound cleaning is paramount; boosters may be required for injuries if more than 5 years have passed since the last dose. ◦ Botulism: A toxin-mediated infection causing generalized weakness, poor feeding, and a weak cry in infants, treated with Botulinum immune globulin.• Systemic & Soft Tissue Infections: ◦ Osteomyelitis: A bacterial bone infection (commonly S. aureus) presenting with fever, irritability, and tenderness. Management requires a long-term course (4–6 weeks) of antibiotics. ◦ Scarlet Fever: Resulting from Group A Strep, symptoms include high fever and a rash on the face and trunk. Droplet precautions are necessary.Vector-Borne & Parasitic ConditionsNurses must distinguish between self-limiting conditions and those requiring targeted medication to prevent complications.• Tick-Borne Diseases: ◦ Lyme Disease: Identified by a ring-like rash and joint pain. Without antibiotics (Doxycycline for children >8 years; Amoxicillin for <8 years), it can lead to neurological complications like cranial nerve palsy. ◦ Rocky Mountain Spotted Fever: Causes fever and rash; treated with Tetracycline.• Common Infestations: ◦ Pediculosis Capitis (Lice) & Scabies: Both cause intense pruritus (itching). Lice are treated with manual nit removal and permethrin, while scabies (mite lesions between digits) requires a scabicide left on for 8–14 hours. ◦ Pinworm: Characterized by anal itching and restlessness; diagnosed via a "tape test" and treated with anti-parasitics like mebendazole.Core Nursing Interventions (The Vital Few)The effectiveness of medical treatment relies heavily on supportive nursing care focused on prevention, comfort, and education.• Infection Control: Prevention is the first line of defense, including hand washing, adequate immunization, and proper food handling.• Symptom Management: ◦ Fever & Pain: Administer analgesics, encourage fluids, and dress febrile children in light clothing. Cool mist humidification aids respiratory comfort. ◦ Skin Integrity: Monitor rashes for infection. To prevent damage from scratching, keep fingernails short and apply antipruritics or cool compresses.• Patient Education: Teaching should be conducted in short sessions using multiple learning modes (visual, auditory). Nurses must assess the family's willingness to learn and provide reinforcement
