We present a case of placental abruption necessitating emergency cesarean section in an otherwise uncomplicated patient soon after initiation of combined spinal-epidural analgesia in labor. Administration of spinal opioids has the potential to cause fetal bradycardia due to uterine hypertonicity following rapid onset of analgesia. In this case, a previously bloody show before placement of combined spinal-epidural analgesia may have been evidence of a small abruption. We hypothesize that uterine hypertonicity following administration of spinal opioids may have hastened the development of an existing placental abruption.
我们报告了一例胎盘早剥的病例,该患者在接受联合脊髓-硬膜外镇痛后不久,在分娩时发生了单纯性胎盘早剥,需要紧急剖宫产。由于镇痛迅速起效,脊髓阿片类药物的使用可能导致子宫张力过高,从而引起胎儿心动过缓。在这种情况下,在放置联合脊髓-硬膜外镇痛之前出现的血性阴道分泌物可能是胎盘早剥的早期表现。我们推测,脊髓阿片类药物给药后子宫张力过高可能加速了原有胎盘早剥的发展。
