    Abstract:
    OBJECTIVE: To describe the long-term outcome of very preterm infants receiving prolonged sedation and/or analgesia and examine the relationship between prolonged sedation and/or analgesia and this long-term outcome. DESIGN: A prospective population-based study (Etude EPIdémiologique sur les Petits Ages GEstationnels [EPIPAGE]). To reduce bias, the propensity score method was used. SETTING: Nine regions of France. PARTICIPANTS: The study population included very preterm infants of fewer than 33 weeks' gestational age, born in 1997, who received mechanical ventilation and/or surgery. Main Exposure Prolonged exposure to sedative and/or analgesic drugs in the neonatal period, defined as exposure of more than 7 days to sedative and/or opioid drugs. MAIN OUTCOME MEASURE: Presence of moderate or severe disability at 5 years of age. RESULTS: The analysis concerns 1572 premature infants who received mechanical ventilation for whom information about exposure to prolonged sedation and/or analgesia in the neonatal period was available. A total of 115 were exposed and 1457 were not exposed. There was no significant difference between the number of patients lost to follow-up from the group of very preterm infants who were exposed to prolonged sedation and/or analgesia and the group who were not. Exposed very preterm infants had severe or moderate disability at 5 years (41/97; 42%) more often than those who were not exposed (324/1248; 26%). After adjustment for gestational age and propensity score, this association was no longer statistically significant (adjusted relative risk, 1.0; 95% confidence interval, 0.8-1.2). CONCLUSION: Prolonged sedation and/or analgesia is not associated with a poor 5-year neurological outcome after adjustment for the propensity score.
