Abstract
GAINZA-ZAYAS, Silvio et al. Empleo de solución salina hipertónica en el transoperatorio de tumores cerebrales. Anest. Méx. [online]. 2016, vol.28, n.1, pp.4-10. ISSN 2448-8771.
A quasi-experimental study was conducted in patients scheduled for elective surgery (craniotomy for removal of glial tumors) intracranial techniques by the neurosurgery service at the Provincial General Hospital University "Carlos Manuel de Céspedes" of Bayamo, Cuba in order to assess the effectiveness of the use of two types of saline solutions, with varying degrees of tone, its electrolytic and metabolic behavior. The two types of studied solutions were, saline solution 0.9% and hypertonic to 7.5%.
Results.
Both solutions were fairly stable and the variables studied, were kept within acceptable parameters, without significant changes. With the use of hypertonic saline to 7.5% there was a significant decrease in arterial pH and a decrease in serum potassium concentration. A respiratory alkalosis appeared in almost all the patients of the study in relation to hyperventilation. Serum osmolarity and the natremia remained within normal limits. In the group of hypertonic to 7.5%, sodium and potassium showed an increase in the first quantification (P = 0.001) and (P = 0.004) respectively.
Keywords : brain tumors; hypertonic saline; acid-base balance.
