[Effects of fasting and infusion of acid-base balance, electrolyte and plasma glucose level in children during operation].

We studied the effects of fasting and infusion different fluid on acid-base balance, electrolyte and plasma glucose level in 50 children during operation. After whole night fasting, 26 of 44 children (59.1%) were found to have metabolic acidosis, and 5 of 42 children (11.9%) have hypokalemia. The serum K+ level of 30 of 42 children (71.4%) and the serum Na+ level of 6 of 48 children (12.5%) were lower than normal. The serum Cl- level of 21 of 48 children (43.8%) was higher than normal. The serum glucose level of 6 of 48 children was lower than normal. One of 48 children (2.1%) had hypoglycemia. The effects of infusing deferent fluids on acid-base balance, electrolytes and plasma glucose level were compared. The results showed that in patients infusing 10% dextrose with Ringer's solution or 5% Dextrose with normal saline, the plasma glucose level, electrolytes maintained at the normal level or acidosis corrected significantly. It is suggested that 10% dextrose with Ringer's solution and 5% dextrose with normal saline are infused during operation for children.
