Association between Parity and Preterm Birth-Retrospective Analysis from a Single Center in Poland.

Preterm births and parity are two medical areas that seem to be entirely different from each other. The aim of this study was to analyze the relationships between parity and maternal and neonatal outcomes associated with preterm birth. This study involved a retrospective analysis of electronic medical records from St. Sophia Hospital in Warsaw (Poland). This study was conducted among women who gave birth to preterm infants between 1 January 2017 and 31 December 2021. A total of 2043 cases of preterm births were included in the final analysis. A higher odds ratio of preterm birth in primiparas was found in women living in a city/town (OR = 1.56) and having secondary (OR = 1.46) and higher education (OR = 1.82). Multiparas who gave birth to preterm infants were more frequently diagnosed with gestational diabetes (19.69%) than primiparas. Multiparas were more likely to give birth to preterm infants who received an Apgar score of ≤7 both at 1 and 5 min after birth (25.80% and 15.34%). The results of our study emphasize the differences between primiparas and multiparas who give birth to preterm infants. Knowledge of these differences is essential to improve the perinatal care provided to mothers and their infants.

Epidural anesthesia during childbirth - retrospective analysis of maternal and neonatal results.

OBJECTIVES: In Poland, in accordance with applicable regulations, every woman should have access to epidural anesthesia. The advantage of this type of analgesia is primarily analgesic effectiveness. The aim of the study is to identify variables related to epidural anesthesia and to verify the relationship between them and the occurrence of perinatal complications in the mother and the child. MATERIAL AND METHODS: This was a single-center retrospective cohort study. Electronic documentation of patients of the Hospital of St. Sofia in Warsaw was used to create an anonymous retrospective database of all births in the years 2015-2020. 27,340 cases were qualified for the analysis. RESULTS: The logistic regression model showed that the risk of episiotomy (OR = 5.539; CI = 5.169-5.935) increases more than fivefold and perineal laceration (OR = 2.190; CI= 2.036-2.356) increases twice in the case of epidural anesthesia application. There is also an increased risk of operative delivery (OR = 2.668; CI = 2.255-3.156), at the same time the risk of performing a cesarean section decreases more than fivefold (OR = 0.043; CI = 0.036-0.052). CONCLUSIONS: Epidural anesthesia affects the delivery mechanism leading to an increase in the number and intensity of additional medical procedures - episiotomy, perineal laceration, operative delivery. The rationale for the routine use of this method of anesthesia should be considered in the context of the implications for the woman's reproductive health and research on the effectiveness of other methods of birth anesthesia should be conducted.

Use and Effects of Augmentation of Labor with Oxytocin: A Single-Center, Retrospective, Case-Control Study of 4350 Women in Warsaw, Poland, 2015-2020.

BACKGROUND Although there have been some recent clinical trials on the effects of augmentation of labor with oxytocin, or augmentation of labor, there are no clinical guidelines to explain the variations in obstetric practice between countries and within countries. This retrospective case-control study from a single center in Warsaw, Poland aimed to evaluate the use and effects of augmentation of labor with oxytocin in 4350 women between 2015 and 2020. MATERIAL AND METHODS This was a single-center, retrospective, case-control study in which 29 455 cases were qualified for analysis. The study included the analysis of 2 groups: the study group consisted of 4382 patients who underwent stimulation of childbirth, and the control group consisted of 25 073 patients who did not undergo this obstetric procedure. RESULTS Multivariate logistic regression analysis showed that the factors increasing the frequency of augmentation of labor were higher BMI (P<0.05), preinduction (P<0.05), epidural anesthesia (P<0.05), and family present at birth (P<0.05). Factors influencing reduction in the frequency of augmentation of labor were higher number of deliveries (P<0.05), vaginal birth after cesarean (P<0.05), and pre-pregnancy hypertension (P<0.05). CONCLUSIONS This study from a single center in Poland showed that BMI, preinduction, epidural anesthesia, and family present at birth significantly increased the frequency of labor stimulation with oxytocin. However, a history of previous pregnancies, previous cesarean sections, and pre-pregnancy hypertension significantly reduced the frequency of augmentation of labor with oxytocin.

Retrospective Analysis of the Factors Affecting the Induction of Childbirth in 4350 Women from a Single Center in Warsaw, Poland.

Labor induction is one of the most common procedures performed during childbirth, on average in 20−30% of all pregnant women. The aim of this paper was to perform a retrospective analysis of the factors influencing the induction of childbirth. The data provide population-based evidence for Poland (Masovian Voivodeship). The electronic patient records of a hospital in Warsaw were used to create an anonymous retrospective database of all deliveries from 2015 to 2020. The study included an analysis of two groups of patients. The study group consisted of patients with labor induction­4350 cases, and the control group of patients with spontaneous contractions­20,345. The factors influencing the lower frequency of labor induction in the study group were previous cesarean section (OR = 0.73, 95% CI: 0.64−0.84, p < 0.05) and a higher number of deliveries (OR = 0.74, 95% CI: 0.68−0.80, p < 0.05). It is necessary to conduct further research about obstetric procedures used during childbirth, such as induction of childbirth, to reduce the risk of complications and improve the perinatal care of the mother and the neonate.

Episiotomy for Medical Indications during Vaginal Birth-Retrospective Analysis of Risk Factors Determining the Performance of This Procedure.

The WHO (World Health Organization) recommends that the percentage of perineal incisions should not exceed 10%, indicating that this is a good goal to achieve, despite the fact that it is still a frequently used medical intervention in Poland. The risk factors for perineal incision that have been analyzed so far in the literature allow, among others, to limit the frequency of performing this procedure. Are they still valid? Have there been new risk factors that we should take into account? We have conducted this study to find the risk factors for performing perineal incision that would reduce the frequency of this procedure. The aim of the study was to check whether the risk factors that were analyzed in the literature are still valid, to find new risk factors for perineal incisions and to compare them among Polish women. This was a single-center retrospective case-control study. The electronic patient records of Saint Sophia's Hospital in Warsaw, Poland, a tertiary hospital was used to create an anonymous retrospective database of all deliveries from 2015 to 2020. The study included the analysis of two groups, the study group of patients who had had an episiotomy, and the control group-patients without an episiotomy in cases where an episiotomy was indicated. A logistic regression model was developed to assess the risk factors for perineal laceration. Independent risk factors for episiotomy in labor include oxytocin use in the second stage of labor (OR (Odds Ratio) = 6.00; 95% CI (Confidence Interval): 4.76-7.58), the supply of oxytocin in the first and the second stage of labor (OR = 3.18; 95% CI: 2.90-3.49), oxytocin use in the first stage of labor (OR = 2.72; 95% CI: 2.52-3.51), state after cesarean section (OR = 2.97; 95% CI: 2.52-3.51), epidural anesthesia use (OR = 1.77; 95% CI: 1.62-1.93), male gender (OR = 1.10; 95% CI: 1.02-1.19), and prolonged second stage of labor (OR = 1.01; 95% CI: 1.01-1.01). A protective factor against the use of an episiotomy was delivery in the Birth Centre (OR = 0.43; 95% CI: 0.37-0.51) and mulitpara (OR = 0.31; 95% CI: 0.27-0.35). To reduce the frequency of an episiotomy, it is necessary consider the risk factors of performing this procedure in everyday practice, e.g., limiting the use of oxytocin or promoting alternative places of delivery.

Spontaneous Perineal Trauma during Non-Operative Childbirth-Retrospective Analysis of Perineal Laceration Risk Factors.

Childbirth-related perineal trauma (CRPT) is defined as damage to the skin, muscles of the perineum, as well as to the anal sphincter complex and anal epithelium. The aim of the study was to analyze the risk factors for spontaneous injuries to the soft tissues of the birth canal during non-operative delivery. This was a single-center retrospective case-control study. The study included the analysis of two groups, the study group featured 7238 patients with spontaneous perineal laceration (any degree of perineal laceration) and the control group featured patients without perineal laceration with 7879 cases. The analysis of single-factor logistic regression showed that the factors related to perineal laceration during childbirth are the age of the patients giving birth (p = 0.000), the BMI before delivery (p = 0.000), the number of pregnancies (p = 0.000) and deliveries (p = 0.000), diagnosed gestational diabetes (p = 0.046), home birth (p = 0.000), vaginal birth after cesarean (VBAC) (p = 0.001), the use of oxytocin in the second stage of childbirth (p = 0.041), the duration of the second stage of childbirth (p = 0.000), body weight (p = 0.000), and the circumference of the newborn head (p = 0.000). Independent factors that increase the risk of perineal laceration during childbirth are an older age of the woman giving birth, a history of cesarean section, a higher birth weight of the newborn, and factors that reduce the risk of spontaneous perineal trauma are a higher number of deliveries and home birth.

A Questionnaire-Based Study to Evaluate Health-Related Behaviors in 602 Women of Reproductive Age in Poland.

BACKGROUND Women's health and undertaking health behaviors during the reproductive period by women, especially during pregnancy, are an important indicator that is reflected both in their own health and in health of their children. This study aimed to use a questionnaire to evaluate the health-related behaviors in women of reproductive age in Poland. MATERIAL AND METHODS The studies were conducted among 602 women of reproductive age by diagnostic poll method with the use of questionnaire technique. The applied tool was an original on-line questionnaire. A link to the questionnaire was sent to women aged 18-49 years using the snowball sampling technique and was posted on thematic pro-health website forums. RESULTS The majority of women participating in the study exhibited health behaviors on the average level (65.3%; M=7.6). Pro-health behaviors were exhibited mainly by women with higher education (M=7.7; SD=2.6), married women (M=8.0; SD=2.6), and women who were pregnant at the time (M=8.8; SD=2.6). However, single women participating in the study consumed alcohol more often (80.6%). The observed relationships were statistically significant (P<0.05). CONCLUSIONS This survey showed that younger women with no children were significantly less likely to be aware of positive health-associated behaviors and lifestyle when compared with older women with children. This small study supports the importance of health education in young women before they have children.
