UnlabelledThe aim of this study was to examine the influence of a continuous infusion of epinephrine (adrenaline) on mean arterial blood pressure (MABP), heart rate, urine output and base deficit in very low birthweight infants (VLBWI) with systemic hypotension. In VLBWI who received an infusion of epinephrine for at least 12 h the mean urine output, administered fluid volume, base deficit and administered buffer 12 h before and 12 h during the infusion were recorded. If the infusion was shorter, but given for at least 2 h, the mean heart rate and MABP 2 h before and 2 h during the infusion were recorded. Thirty-one infants with a gestational age of 26 (23-30) wk [median (minimum-maximum)] and birthweight 690 (390-1310) g were included in this retrospective chart review. The patients received an infusion of epinephrine at a postnatal age of 3 (1-21) d. The doses ranged between 0.05 and 2.6 microg kg(-1) per minute within the first 24 h of administration. Three of 31 infants received epinephrine on 2 different occasions. The MABP [+7 (-1 to 13) mmHg, p=0.000001] and the heart rate [+10 (-10 to 42) bpm, p=0.000036] increased significantly (n = 34), whereas total volume administration and urine output remained the same between the 2 periods (Wilcoxon matched pairs test). The base deficit increased significantly [-3 (-10.2 to 2.6), p = 0.0014, n = 19] without a change in the administration of buffer.ConclusionThe infusion of epinephrine increased the MABP and the heart rate without decreasing urine output in VLBWI with hypotension not responding to a dopamine infusion up to 15 microg kg(-1) per minute. A potential adverse effect was an increase in metabolic acidosis.
