title: Acute premature constriction of the ductus arteriosus after maternal self-medication with nimesulide.
abstract: OBJECTIVE
  To describe clinical findings in a case of premature ductal constriction associated with maternal use of nimesulide, a cyclo-oxygenase type-2 inhibitor.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A mother self-administered nimesulide at 39 weeks of gestation due to lower back pain. Less than 24 h later premature ductal constriction was diagnosed by echocardiography following a suspicious fetal heart rate recording with baseline tachycardia and absent accelerations.
  
  
  CONCLUSIONS
  In a term pregnancy, nimesulide administration can rapidly cause premature ductal constriction. This condition may induce abnormalities in the fetal heart rate trace.
