Impact of parity and intrauterine fetal condition during vacuum extraction.

PURPOSE: The main goal of this study was to investigate the impact of parity and intrauterine fetal condition on vacuum extraction.

MATERIAL AND METHODS: This study included 10742 newborns who were delivered during 2008 in obstetrics/gynecology clinics in Kosovo, Yugoslavia. One hundred fifty-eight of these were vacuum deliveries. Data were collected for indicators such as parity, maternal age, gestation duration, newborn vitality, and birth weight.

RESULTS: Vacuum extraction was used in 158 cases (1.47 %), of whom 116 (73%) were nulliparous and 42 (27%) were multiparous. In 121 cases (76.5%), vacuum extraction was performed in women with no history of abortion, and 101 (64%) of the women were aged 21-30 years. The main reason for vacuum extraction in 115 women (72%) was arrest (stasis) in the second stage of labor. Vacuum extraction was carried out at a gestational age of 34-40 weeks in 94 cases (59.5%). Amniotic fluid was clear in 125 cases (80%), and meconial amniotic fluid was seen in three cases (1.8%). Birth weight was > 3.5 kg in 77 infants (48.5%) and < 2.5 kg in seven (4.5%). Apgar score (AS) was 0-3 in 19 (12%), 4-7 in 129 (81.6%), and 8-10 in eight (6.4%) infants. In 91 cases (57.6%), newborn resuscitation was necessary and neonatal complications occurred in 11 cases (6.96%).

CONCLUSIONS: We conclude that vacuum extraction was performed mostly in nulliparous women aged 21-30 years. Most newborn infants had a birth weight of > 3.5 kg, the most frequent AS was 4-7, and newborn resuscitation was needed in most cases.
