摘要：
OBJECTIVE: To determine the effects of low-dose dopamine on urine output (UOP) in very low birth weight premature neonates. STUDY DESIGN: Retrospective cohort study of all low-dose (3-5 mu g kg(-1) per min) dopamine infusions >24-h duration in neonates <= 1500 g and <= 32 weeks gestation from August 2009 through September 2011. Linear regression was used to estimate the impact of covariates on UOP. RESULT: We identified 91 episodes of low-dose dopamine use in 65 neonates. Increased UOP occurred in 64% of episodes. Low-dose dopamine use was associated with a 0.6 ml kg(-1) h(-1) increase in UOP (P<0.001) and a 1.3 ml kg(-1) h(-1) increase when baseline UOP was <1.5 ml kg(-1) h(-1) (P<0.001). The improvement remained statistically significant after controlling for medications (diuretics and hydrocortisone) and fluid intake. CONCLUSION: Low-dose dopamine use was associated with increased UOP in very low birth weight neonates.
