Use of sodium nitroprusside in neonates: Efficacy and safety

https://doi.org/10.1016/S0022-3476(85)80477-7Get rights and content

Sodium nitroprusside was administered to 58 neonates, including 11 with severe respiratory distress syndrome, 15 with persistent pulmonary hypertension of the newborn, 28 with clinical shock, three with systemic hypertension, and two with pulmonary hypoplasia, all refractory to conventional intensive therapy. Nitroprusside was infused at 0.2 to 6.0 μg/kg/min for periods of 10 minutes to 126 hours. Infants with severe respiratory distress syndrome had increased Pao2 and decreased Paco2 or peak inspiratory pressure, and nearly all (82%) survived. Infants with persistent pulmonary hypertension of the newborn had variable responses; improvement did not correlate with survival, but survival (47%) was identical to that in an earlier series of infants given tolazoline. Infants in shock had improved perfusion, urine output, and serum bicarbonate levels, and these responses were significantly related to survival. Hypertension was controlled in all three hypertensive infants. Adverse effects were very uncommon. Toxic effects were not observed. Sodium nitroprusside is effective and can be used safely in circulatory disorders in the neonate.

      Given risk for side effects in general it is helpful to avoid using ACE inhibitors until after infants have reached a corrected postmenstrual age of 44 weeks.2,74,75 In neonates with acute severe hypertension, continuous intravenous infusions, such as nicardipine, sodium nitroprusside, esmolol, and labetalol, have the important benefit of being easily titratable to keep the blood pressure within the desired range.39,75–82 When used, blood pressure should be monitored continuously using an indwelling intra-arterial catheter or if necessary, an automated oscillometric device taking regular repeat blood pressure measurements.

      Several case series suggest that the intravenous calcium channel blocker nicardipine may be particularly useful in infants with acute severe hypertension [77,78]. Other intravenous antihypertensives that have been reported effective in neonates include sodium nitroprusside, esmolol, and labetalol [79–81]. Whenever intravenous infusions are used, the neonate's BP should be monitored continuously, preferably via an indwelling arterial catheter, alternatively using an automated device to obtain repeated cuff readings, so that the infusion can be titrated to the desired BP reduction.
