Adenylate kinase activity in the cerebrospinal fluid of hypoxic newborns.

Adenylate kinase (AK) activity in the cerebrospinal fluid (CSF), described as a marker of brain edema and lesions in adults, was studied in 79 newborns with severe respiratory distress within 24 h after admission to the Intensive Care Unit (ICU). The CSF-AK activity was compared with CSF lactate concentration, CSF lactate dehydrogenase activity (LDH), and CSF and serum creatine kinase isoenzyme BB (CK-BB) activity. Newborns were divided into Group I with moderate to severe brain dysfunction and Group II with mild or no detectable brain dysfunction on discharge from the ICU. Mean CSF-AK activity (11.31 U/L) in Group I was significantly (p less than 0.001) higher than in Group II (2.82 U/L). Correlation between CSF-AK and CSF lactate was r = 0.714, p less than 0.01 and between CSF-AK activity and CSF-LDH activity was r = 0.550, p less than 0.01 in Group I. Preliminary data indicate that CSF-AK activity within 24 h after ischaemia is an indicator of hypoxic brain lesions in newborns. Its prognostic value for the infant's development remains to be determined by further study.

The bactericidal mats in the pediatric intensive care unit.

An evaluation of dry adhesive bactericidal mats S-Entry was conducted in pediatric intensive care unit (ICU). From April to June 1981 192 floor and 48 shoe samples were taken in three parallels in the periods with the mats used and in the periods without the mats for bacteriological control. The statistical analysis of the number of CFU showed no significant difference between the two periods. Under the conditions of work in the ICU the bactericidal mats cannot play an expected role. The bacterial flora of the floor and shoe soles had no influence on the degree of hospital infections in the ICU.

Parenteral nutrition in severely burned children.

In adults supplemental parenteral nutrition (PN) is advisable in burns over 40% especially when weight loss exceeds 10% of body weight. In children with smaller reserves and higher requirement of proteins and energy no rigid scheme for parenteral supplementation is used at our unit. In a young infant it may be added already at a 20-30% deep burn, especially with connected gastrointestinal tract problems, infection etc. Metabolic and protein requirements are estimated 50-100% in addition to their normal needs. Hypertonic glucose (gradually increased from 20-40%), covered with insulin in the early phase, is used as source of carbohydrates. L-amino acid mixture containing the "pediatric essential amino acids" histidine and cysteine is given as a nitrogen source. 20% Intralipid is given in a gradually increased amount of 2-4 g/kg per day to provide calories and essential fatty acids. Among electrolytes K, Ca, P and Mg must be added. Increased amounts of vitamin C and folate are needed by burned children. Vitamin E is also required during prolonged lipid administration. Trace elements (Zn. Fe, etc.) are supplied orally or i.v. with special solutions or fresh plasma infusions. Our experience with parenteral nutrition in severely burned children will be presented. There were no severe metabolic side-effects but sepsis represented the major problem. The concomitant heat preservation by warming the room and use of infra-red heaters is emphasized.
