ABSTRACT A patent ductus arteriosus (PDA) is common among preterms, and prophylactic medical treatment has been advocated as the first-line approach. Conservative treatment may result in similar outcome, but without exposure to the harmful side effects of medication. A retrospective analysis revealed a ductal closure rate of 94% after conservative treatment with adjustment of ventilation (lowering the inspiratory time and increasing positive end expiratory pressure) and fluid restriction.
To study prospectively over one year the rate of PDA closure, and morbidity and mortality following conservative treatment.
Prospective study (1 January 2005 - 31 December 2005) including 30 newborns <or=30 weeks' gestation, all of whom were being ventilated and required surfactant. Echocardiography was performed 48-72 h after birth. Clinically important PDA was conservatively treated as described above. The percentage of children with PDA, ductal ligation and major complications was determined.
Ten neonates (33%) developed a clinical important PDA. Following conservative treatment the duct closed in all neonates (100%), and none required ductal ligation or medical treatment. The rates of major complications were no higher than those reported by the Vermont Oxford Network and in the literature.
The managed care plan resulted in an overall ductal closure rate of 100%. These results suggest that conservative treatment of PDA is a worthy alternative to prophylactic medical treatment.

    ABSTRACT: Aim. To evaluate whether synchronized-NIPPV (SNIPPV) used after the INSURE procedure can reduce mechanical ventilation (MV) need in preterm infants with RDS more effectively than NCPAP and to compare the clinical course and the incidence of short-term outcomes of infants managed with SNIPPV or NCPAP. Methods. Chart data of inborn infants <32 weeks undergoing INSURE approach in the period January 2009-December 2010 were reviewed. After INSURE, newborns born January -December 2009 received NCPAP, whereas those born January-December 2010 received SNIPPV. INSURE failure was defined as FiO(2) need >0.4, respiratory acidosis, or intractable apnoea that occurred within 72 hours of surfactant administration. Results. Eleven out of 31 (35.5%) infants in the NCPAP group and 2 out of 33 (6.1%) infants in the SNIPPV group failed the INSURE approach and underwent MV (P < 0.004). Fewer infants in the INSURE/SNIPPV group needed a second dose of surfactant, a high caffeine maintenance dose, and pharmacological treatment for PDA. Differences in O(2) dependency at 28 days and 36 weeks of postmenstrual age were at the limit of significance in favor of SNIPPV treated infants. Conclusions. SNIPPV use after INSURE technique in our NICU reduced MV need and favorably affected short-term morbidities of our premature infants.

    ABSTRACT: Failure of the ductus arteriosus to close within 48–96 hours of postnatal age results in a left to right shunt across the ductus and overloading of the pulmonary circulation. This is more likely to happen in premature neonates with respiratory distress syndrome. Deterioration in the respiratory status on day 3–4 in a ventilated neonate and unexplained metabolic acidosis may be the earliest indicators of a patent ductus arteriosus (PDA). Indomethacin is the main stay of medical management of PDA in preterm neonates. Guidelines for administration of indomethacin have been described in the protocol. Restricted fluid therapy may be beneficial in the prevention of PDA in preterm neonates. Presence of PDA in a term neonate should be investigated to rule out an underlying congenital heart disease.
