Childbirth refers to the completion of intrauterine development of the fetus and its expulsion from the uterus or its birth outside, regardless of the duration of the birth act [1].
Labor is considered rapid if timely labor (from 22 to 42 weeks of gestation) from the onset of contractions continues to contract at a rate of 3 Hz or more for 6 hours at 37-4196 days of gestation or at any stage (at any week of pregnancy) with a decrease in heart rate from 3 to less than 3 Hz. [2]. Rapid labor often necessitates the use of obstetric aids to achieve intrapartum fetal survival [3].
There is evidence that women who are pregnant with an above-average growth rate, without the need for uterotonic therapy and obstetric techniques, have a lower risk of complications during pregnancy and childbirth. However, it is not clear whether this result is temporary or long-term [4]
Preembral labor is a rapid labor in preterm preemies (before 34 weeks' gestation), usually occurring in less than 90 minutes after the onset of timely contractions [5]. Approximately 5% of infants born before this date experience decreased survival beyond 1 minute after birth. For preterm infants born during rapid labor, additional support is required to prevent neonatal complications [6].
