Percentage of patients who deliver via cesarean section for whatever reason

Percentage of patients who deliver via instrumental delivery (forceps, a vacuum device) for whatever reason

Oxytocin used prior to the delivery of the baby. If oxytocin was used, we will measure how many international units (IU) of oxytocin were used from the beginning of labor to the delivery of the baby.

Percentage of uterine hyperstimulation- exaggerated uterine response consisting of uterine hypertonus, a single uterine contraction lasting two or more minutes or uterine tachysystole with a least 12 contractions in 20 minutes, with a simultaneous nonreassuring fetal heart rate tracing as defined by the 2015 FIGO (The international federation of gynaecology and obstetrics) classification of intrapartum cardiotocography.

Clinical chorioamnionitis (a fever of 38.0°C or more plus one or more of the following: baseline fetal heart rate > 160 beats/minute for ≥ 10 minutes, maternal white cell count >15,000 cells/mm3 or purulent-appearing fluid coming from the cervical os visualized by speculum examination).

Clinical endometritis (postpartum woman with at least two of the following signs or symptoms: fever ≥38.0°C, pain or tenderness (uterine or abdominal) with no other recognized cause or purulent drainage from the uterus.)

A fever of 38.0°C or more in the postpartum period.

Possible use of antibiotics in the postpartum period.The decision of the need of antibiotics in the postpartum period is in the discretion of the physician.

The decision of the need of antibiotics in the postpartum period is in the discretion of the physician. If antibiotics will be used, we will measure length of antibiotic treatment (in days).

Infants which will be admitted to the neonatal intensive unit for whatever reason.

Infants with a 5-minute APGAR score of less than 7.The Apgar score is a number calculated by scoring the heart rate, respiratory effort, muscle tone, skin color, and reflex irritability of the infant, 5 min after birth. Each of these objective signs can receive 0, 1, or 2 points. The higher is the sum of the points, the better is the condition of the newborn.

Total length of hospitalization of women in days.

Infants with early neonatal sepsis, a diagnosis based on a positive blood, cerebrospinal fluid, or urine microbiological culture in the first 72 hours after birth.

Satisfaction and perceptions of woman giving birth with labour through a self-administered questionnaire that they will answer in the postpartum period (6 to 48 hours after labor). They will specify their level of agreement or disagreement on a symmetric 4-point agree-disagree scale (1- I strongly disagree, 2- I disagree, 3- I agree, 4- I strongly agree) for a series of statements regarding aspects of birth.

With the beforementioned scale we will measure patients' perception of length of hospitalization before childbirth, perception of pain before admission to the labour room, pain associated with vaginal examinations and insertion of the vaginal insert and if they would choose the same method of managing birth in the next pregnancy.
