T. Fosel et al., COMPARISON OF 2 SOLUTIONS WITH DIFFERENT GLUCOSE-CONCENTRATIONS FOR INFUSION THERAPY DURING LAPAROTOMIES IN INFANTS, Infusionstherapie und Transfusionsmedizin, 23(2), 1996, pp. 80-84
Objective: Comparison of two commercially available solutions for intr
aoperative infusion therapy during laparotomies in infants using a sta
ndardized anesthetic technique (combination of general anesthesia with
a caudal block). Design: Prospective, randomized. Setting: Infusion t
herapy during laparotomies in infants. Patients and Methods: 12 infant
s aged 1-12 weeks (group I) and 12 infants aged 5-14 months (group II)
received at random either solution A with 2.5% glucose and 70 mmol Na
+ or solution B with 5.5% glucose and 100 mmol Na+ at a rate of 8 ml/k
g/h. Interventions: Central venous blood samples after induction of an
esthesia and every 60 min for analysis of blood glucose, electrolyte,
and hemoglobin concentrations. End of surgery: urine output during the
operation and urine glucose and sodium concentrations. Statistical si
gnificance within the group: Friedmann Test, between the groups: U tes
t by Wilcoxon, Mann and Witney. Significance: p<0.05. Results (given a
s median and range): In group I blood glucose concentrations rose sign
ificantly during surgery, however, there was no significant difference
between group A or B after 1 h. A: 234 mg/dl (156-351) us B: 239 mg/d
l (166-329)) or 2 h: A: 254 mg/dl (166-331) vs B: 272 mg/dl (176-468).
In group II blood glucose levels rose significantly during surgery, h
owever, children of group B showed significantly higher blood glucose
levels than group A after 1 h [A: 119 mg/dl (114-227), B: 203 mg/dl (1
62-238)], 2 h [A: 154 mg/ml (106-185), B: 284 mg/dl (243-317)] or 3 h
[A: 159 mg/dl (116-218), B: 248 mg/dl (201-363)]. The plasma and urine
sodium concentrations did statistically not differ between the two so
lutions. Conclusions: Solutions containing 5.5% glucose infused with 8
ml/kg/h caused in both age groups of infants intolerable hyperglycemi
as. In young infants. also a solution containing 2.5% glucose infused
at a rate of 8 ml/kg/h leads to hyperglycemia, while in older children
this amount of glucose is tolerated. It is recommended that for abdom
inal surgery in young infants glucose and fluid substitution is separa
ted, in order to infuse glucose at an even lower rate. Still, blood gl
ucose levels have to be monitored closely.
