Amnioinfusión con índigo carmín en sospecha de ruptura prematura de membranas ovulares pretérmino: Serie de casos

摘要

Introduction: the opportune detection and diagnosis of premature rupture of membranes (PROM) reduces unnecessary interventions such as prolonged hospitalisation; nevertheless, diagnosis can be doubtful and requires additional tests. Carmine indigo amnioinfusion is considered to be the gold standard in such cases. Objective: describing carmine indigo amnioinfusion use regarding patients admitted to Clinica Universitaria Bolivariana having suspected PROM. Materials and methods: an observational, case series and retrospective study was carried out on patients 22 and 36+6 weeks after being admitted to hospital. Results: a total of 41 amnioinfusions were done (one patient with twin pregnancy); of them 37 were transamniotic and 4 were across the placenta. Amnioinfusion was positive for PROM in five patients. The complications found were one case of placental abruption in transplacental route and three cases of threatened preterm labour. Four of the patients in whom speculum exam proved negative presented PROM, verified by amnioinfusion. Five patients without PROM presented oligohydramnios; a diagnosis of PROM was confirmed in five patients having normal amniotic fluid ultrasound. Conclusion: indigo carmine amnioinfusion is a diagnostic test having few complications and is useful in a clinical approach to patients having suspected PROM.
