Keywords:
premature birth, pregnancy, cervical patency, cervicometry, cervical pessaryAbstract
Introduction:
Preterm birth is complex and multifactorial. Cervicometry is based on the premise that there is a relationship between cervical length and the onset of labor.
Objective:
Describing the use of the cervical pessary as a method of preventing prematurity.
Methods:
A descriptive observational study was carried out in a series of cases, municipality of Güira de Melena, province of Artemisa, Cuba, from January 2019 to September 2022. Cervical pessary were place to a sample of 42 pregnant women with single pregnancies and risk cervicometry. The variables analyzed were: gestational age at insertion of the pessary, functional cervical length; patency of the internal cervical orifice and gestational age at the delivery. The statistical program SPSS version 21® for Windows was used for the data. Descriptive statistics were used, with measurements of absolute frequencies, percentages, central tendency and minimum-maximum.
Results:
The gestational age that predominated when placing the pessary was less than 28 weeks with 69%, the average gestational age was 23.4 weeks with a minimum of 22 and a maximum of 32. 73.8 %. of pregnant women, had a functional cervical length between 20.1 mm and 25 mm. 83.3% of patients had a patency of less than five mm. 76 % of pregnant women gave birth after 37 weeks and only 7.1% gave birth between 28 and 33.6 weeks.
Conclusions:
The cervical pessary is used as a method of primary prevention of preterm birth, with a short neck.
