Hiponatremili bir olguda zor entübasyon ve hipoksi

Hyponatremia is a frequent situation that many anaesthesists confront with. Clinical signs are primarely neurological and the severity is dependent on the rate of development of hyponatremia. Na concentration of 130 mEq L^-1 is thought to be safe for patients who would undergo general anaesthesia. Although there is no clinical symptoms, plasma sodium should be raised above 130 mEq L^-1 for all elective operations. Lesser concentrations cause peroperative decreased minimum alveolar concentration or postoperative significant serebral eudema causing agitation, confusion or somnolence. Hyponatremia by itself or in combination with hypoxia may cause severe neurological deficit. Postanacsthesic neurological deficit of a patient with hyponatremia and hypoxia was discussed in this paper.
