[Perioperative infusion therapy during childhood. II. Balance studies on pre-, intra- and postoperative infusion of basic solutions].
For a period of 63 hours totally, 4 different infusion solutions were administered to infants and children of 3 age groups (I = 10th day to the 6th month of age, II = 6th month to the 3rd year of age and III = above 3 years of age) during the pre-, intra- and postoperative period. The serum sodium, potassium-, chloride-, phosphate- and blood urea concentrations remained completely unchanged as well as the acid base parameters. Even between the age groups, no significant differences could be observed, as far as the above mentioned criteria are concerned. But the blood glucose concentrations increased within all age group in the immediate postoperative phase. The potassium concentrations in the urine decreased throughout in age group I. From these results, one can conclude, that these specific infusion solutions for paediatric surgical procedures with exception of solution I contained the most important electrolytes adaequately and that the amounts of fluids, which were given can be considered as sufficient. Nevertheless, the question remains, whether these different types of infusion therapy can be simplified by using more standardized solutions. This problem was subject to more sophisticated studies, which will be reported in the 3rd part of this publication, to be published at a later date.
