Not all women with weak contractions need to be given contractions. In women with coordinated weak contractions, if the foetal heartbeat is good, the foetal position is normal and the foetus is in proportion to the pelvis, the doctor will use contractions appropriately to promote contractions and speed up the progress of labour.
However, the use of contractions may lead to complications such as allergy, cardiac arrhythmia, hypotension, amniotic fluid embolism and water intoxication, so doctors will closely monitor the intensity of contractions, fetal heart rate, blood pressure and progress of labour and adjust the dosage of contractions in time.
Doctors will not usually use contractions in women who have uncoordinated weak contractions, or in cases of fetal-pelvic disproportion, uterine overdistension, abnormal fetal position, placenta praevia, preterm labour, intrauterine hypoxia, women who are elderly primigraviders, or who have a history of uterine or cervical surgery.
