Based on Table 8, it is known that the most use of Nifedipine drugs with cured status was 12 (50.0%)
samples. The Fisher Exact Test obtained a value = 0.542 where p >0.05. This means that there is no significant
relationship between drug use and cure in pregnant women with premature parts imminent (Widiana, Putra,
Budiana, & Manuaba, 2019).
Sample Characteristics
Pregnant women with the threat of preterm labour or Partus Prematurus Imminens (PPI) at PKU
Muhammadiyah Gamping Hospital Yogyakarta for 5 years (2016 – 2021) were found to have as many as 53
people as research subjects. The patient's medical records found with data were quite complete, as many as 24,
so only 24 subjects could be taken for this study. Twenty-four subjects were studied, and most pregnant women
were classified as productive age group (20-35 years), namely as many as 22 people (91.7%). This shows that
in terms of age, pregnant women at PKU Muhammadiyah Gamping Hospital Yogyakarta, the research subjects,
are the productive age group. High-risk pregnancies are pregnancies that can cause pregnant women and babies
to become ill and die before delivery takes place (Nuryanti, 2021)v. Babies die or are disabled, and even mothers
die during childbirth, often in pregnancies aged 35 years and over. There are many risk factors for pregnant
women, and one of the important factors is age. Pregnant women at the age of more than 35 years are at higher
risk of getting pregnant than when pregnant at a normal age, which usually occurs around 21-30 years. Aged
35 years and over, babies born are susceptible to genetic disorders. At reproductive age (25-35 years), the risk
of babies experiencing genetic disorders is 1:1000, while in mothers over 35 years old, the risk increases to 1:4.
Therefore, the age of the mother for childbirth should be in the range of 25-35 years (Shibuya et al., 2013). In
addition, a person's age can also affect a person's information and experience, which this study is about the use
of tocolytic therapy in pregnant women with premature parts imminent. Someone who gets more information
will add broader knowledge, while experience, which is something someone has done, will increase knowledge
about something informal (Maharani, 2021).
Incidence of Preterm Labor
The incidence of preterm labour or Partus Prematurus Imminens (PPI) at PKU Muhammadiyah Gamping
Hospital Yogyakarta, which was recorded for 5 years (2016 – 2021), was 55 people. Partus Prematurus
Imminens (PPI) or preterm labour is a threat of labour that occurs in the third trimester (28-40 weeks). This
arises due to uterine contractions at <37 weeks gestation caused by many factors from the mother. The main
signs or symptoms of the presence of preterm labour itself are contractions in the uterus; the use of tocolytic
therapy can inhibit uterine contractions aimed at prolonging gestational life and delaying labour. Another
problem that can occur during preterm labour lies in the baby; babies born prematurely will have a higher risk
of death compared to babies born normally (Zulaikha & Minata, 2021). Preterm labour is dangerous because it
has the potential to increase perinatal mortality by 60-80%; usually, preterm labour is associated with low birth
weight (BBLR). Low birth weight (BBLR) is caused by premature birth and stunted fetal growth (POGI, 2011;
Clinical Practice Guideline, 2015). Some risk factors that play a role in parts premature imminent include
multiple pregnancies, polyhydramnios, uterine anomalies, cervical dilation at 32 weeks gestation, history of
abortion 2 or more times in the second trimester, history of previous preterm labour, history of undergoing
surgical procedures on the cervix, cervical flattening/shortening of less than 1 cm in 32 weeks of pregnancy,
and abdominal surgery after the first trimester (Andalas et al., 2018).
