NURS407 Study Guide - Midterm Guide: Fluid Replacement, Eschar, Spinal Cord Injury
Document Summary
Burns readings key notes: young people and elderly at high risk for burn injury skin is fragile and thin. 4 major goals: prevention, livesaving measures for severely burned person, prevention of disability and disfigurement through early, specialized, individualized treatment, rehabilitation. Factors: how injury occurred, causative agent, temperature, duration of contact, thickness of skin. Palm method palm is 1% to estimate smaller burns. Hemodynamic instability resulting from loss of capillary integrity and subsequent shift of fluid, na, and protein from intravascular space into interstitial spaces. Cardiovascular response: hypovolemia cardiac output falls, then bp drops = burn shock . Sympathetic nervous system releases catecholamines (increase pvr/vasoconstriction) and increase pulse rate further decrease co: myocardial contractability suppressed. To maintain blood pressure and cardiac output: greatest fluid leak 6-8hrs (first 24-36hrs) Burn edema: more severe burns develop systemic edema (max at 24hrs, compartment syndrome = pressure on small blood vessels and nerves in distal.
