| Abstract | The possible changes in acid-base and electrolyte balance in children undergoing elective surgery in the oropharyngeal region under relatively short general anaesthesia were investigated. A comparison was made with the corresponding parameters in a group of children undergoing longer anaesthesia and major orthopaedic surgery. Simultaneously, possible changes in blood picture, body temperature, blood pressure and pulse rate were monitored in the operated children. Arterialized blood of the hyperaemized ear was analyzed in 90 children. The analysis was carried out five minutes prior to and five minutes after surgery. The blood gas analysis was done with the radiometric method on a type 990 AVL pH blood gas analyzer while the serum electrolyte analysis was done by indirect ISE potentiometry on a type 911 Hitachi analyzer. Changes in body temperature were confirmed with a Hellige rectal probe for measuring body temperature. By statistical analysis the significance of changes (p<0.05) was determined separately for the group of subjects after short anaesthesia (<60 min) and the group after a longer procedure (<60 min) as well as the significance of changes for all operated children. The results of gas analysis show a tendency of the pH value of arterialized blood to drop in the majority of patients and a statistically significant drop in serum pH and bicarbonate values in children after longer procedures (drop of mean pH value from 7.41 to 7.31, p<0.01 and drop of mean bicarbonate value from 23.39 to 20.68 mmol/L, p<0.01). There is poof of a tendency to develop metabolic acidosis as the drop in serum bicarbonate is expressed more strongly than the increase in pC02. The analysis of changes in serum electrolyte concentration shows no statistically significant changes in serum sodium, potassium or chloride concentrations. Nevertheless, a tendency to a drop in serum sodium concentration was proven (p<0.05). (Abstract truncated at 2000 characters) | |
