CAMACHO CRUZ, Marilyn; GARCIA SAINZ, Mario; GARCIA MOREIRA, Gloria Beatriz  and  CAMACHO CRUZ, Lizbeth. Vaginal progesterone combined with nifedipine in The prevention of pretermine labor with short cervix. Gac Med Bol [online]. 2017, vol.40, n.2, pp. 08-11. ISSN 1012-2966.

Objective: evaluate the effects of Vaginal Progesterone combined with nifedipine compared to the single use of nifedipine in the threat of preterm delivery in pregnant women between 24-34 weeks with cervical length ≤ 25mm in the Hospital Materno Infantil Germán Urquidi. Method: a prospective, comparative and analytical cohort study was conducted. It is a design of two groups (comparative) where the selection of patients was made according to inclusion and exclusion criteria, we evaluated 231 patients. Results: the time to exceed the Preterm Childbirth episode, 67% of the patients who used progesterone plus nifedipine resolved the event within the first hour compared to 50% of patients who used only nifedipine. With the combination of progesterone and nifedipine, the episode of Premature Birth Threat between 24 and 34 weeks of gestation was controlled within 1 hour, with the sole use of nifedipine, from 32-34 weeks there is an average of 2 hours in excess of episode. With only nifedipine as tocolytic, 80% of the patients verified delivery at 5 days. Only 20% were able to exceed 10 days of latency. The combination progesterone + nifedipine achieved that 30% of the patients reached a latency between 21-30 days, Gestational age at birth with the combination progesterone + nifedipino reaches 80% an age less than or equal to 37 weeks 6 days. Conclusions: the combination of vaginal progesterone plus nifedipine substantially improves the neonatal prognosis in all the results obtained, the use of nifedipine alone has less beneficial effects in this investigation.
