Document Summary
In food: body fluid volumes, daily water balance (liters, fluid intake, metabolic 0. 3, total. Insensible 0. 8: sweat, feces, urine, total, composition of fluids (mmol/l) 10: fluid replacement, 0-10 kg, 11-20 kg, > 20 kg, 4-2-1 (ml/kg/h) Patient (70 kgs: 1-10 kg, 11-20 kg, >20 kg 1 ml/kg/h (4-2-1) 2640ml/d: fluid balance, the main way to regulate body water gain is by adjusting the volume of water intake, mainly by drinking more or less fluid. Isonatremic (isotonic: hyponatremic (hypotonic, hypernatremic (hypertonic, disturbances of fluid homeostasis. Intracellular fluid volume remains constant: causes: renal failure, heart failure; decreased oncotic pressure, increased isotonic fluid intake. Increase rate of se na level should be less than 2 mmol/h (cave: central pontin myelinolysis: hypernatraemia, se na > 145 mmol/l, causes: inadequate water intake and increased free water loss; intake of hypertonic sodium solution, symptoms: Insulin (+glucose: sodium bicarbonate, 2-adrenergic agonists, hyperkalaemia, therapy, removal k from the body.
