Prevalencia del incremento del Índice de Pulsatilidad de las arterias uterinas y factores asociados en embarazadas, Hospital Vicente Corral Moscoso, 2017

Abstract:

Objective To determine the prevalence and associated factors with the increase in the Pulsatility Index of uterine arteries greater than 95th percentile in pregnant women between 11-14 weeks of gestation treated at Hospital Vicente Corral Moscoso during the 2017 year. Methodology A descriptive study was conducted with analysis of associated factors in 254 pregnant women from 11 to 14 weeks of gestation. The sample size was measured with a 12 % of prevalence, 95 % of confidence level, and 4 % of precision and infinite population. The data were collected using direct interview, transvaginal ultrasound was performed, the Pulsatility Index of the uterine arteries was identified and the average higher than 95th percentile was noted. The information was analyzed in the SPSS system, version 15. Results The minimum age was 15 years, the maximum age of 46, the age group with the highest frequency was 19 to 34 years with 75.6 %, a 76 % were from urban area, a 49.6 % had more than 13 years of schooling, and a 36.6 % were mostly primiparous. The prevalence of the increased Pulsatility Index was 8.7 % and it was associated with the history of pre-eclampsia with RP 3.06, CI: 1.37 – 6.81 and p-value 0.013. Conclusions The Prevalence of the Increased Pulsatility Index in pregnant women from 11 to 14 weeks of gestation was lower to those reported in the literature and it was associated with the history of pre-eclampsia
