precautions and prevention
respiration |
Aspiration, choking Minimize prolonged sitting for certain levels |
autonomic dysreflexia |
T4 or higher Signs & symptoms: elevated blood pressure, pounding headache, perspiring, chills, flushed, decreased heart rate. HTN at risk for hemorrhagic CVA. Activate emergency response Help lower blood pressure Sit upright. Remove abdominal binder Lower legs. Remove compression hose Check for catheter tube, full ladder, foot plate, feet crossed |
orthostatic / postural hypotension |
Recline Abdominal binder & compression hose before |
pressure injuries |
Due to sensation loss Lack of blood flow (necrosis) Ischial tuberosity, superior aspect of gluteal fold, heels, malleoli, elbows, trochanters, scapulae Educate Padding Float heels Repositioning Q-… Minimize shearing |
bowel and bladder |
Risk for infections with catheters Collaborate with nursing Reaching may be difficult for hygiene Lack of sensation may be difficult even with A/E |
