Diuretics for very low birth weight infants in the first 28 days: a survey of the US neonatologists

Objective:the objective of this study was to describe factors influencing diuretic use by neonatologists caring for very low birth weight neonates.study design:we surveyed 400 us neonatologists. respondents made therapeutic decisions in clinical scenarios involving very low birth weight infants at 7, 14 and 28 days of age.result:response rate was 39%. diuretic therapy was chosen in 31% of scenario decisions, with pro re nata dosing selected early and regular dosing more common at later ages. diuretic use was strongly associated with method of respiratory support, and was chosen less often by those also choosing fluid restriction and those concerned about patent ductus arteriosus risk. after adjusting for these factors, excessive weight gain, expected improvement in work of breathing and expected decrease in ventilator days were also associated with diuretic use.conclusion:the extent of and expectations for diuretic therapy by neonatologists caring for very low birth weight neonates may exceed evidence for efficacy.
