Seventy-seven cases of meconium aspiration were documented among 14,527 deliveries. Four cases occurred in early labor and with normal fetal heart tracings. Three cases followed repeat cesarean sections at term, and one followed an elective cesarean section for a primigravid breech presentation. Aggressive airway management was used in every case, and included intrapartum pharyngeal suctioning with a DeLee catheter and intubation of the trachea with suctioning under direct vision. These cases suggest that meconium aspiration may occur before the onset of active labor and without evidence of fetal distress.
在14527例分娩中，记录到77例胎粪吸入病例。4例发生在产程早期且胎儿心率监测正常。3例发生在足月重复剖宫产术后，1例发生在因初产妇臀位行择期剖宫产术后。所有病例均采用了积极的气道管理措施，包括产时用DeLee导管进行咽部吸引以及在直视下气管插管并吸引。这些病例表明，胎粪吸入可能在活跃产程开始前发生，且无胎儿窘迫迹象。
