A total of 1,503 vaginal deliveries with the Shute parallel forceps during a 10 year period are analyzed as to the risk of instrumental damage. In this series, 35 infants died intrapartum or neonatally. Eliminating all deaths from unrelated causes, three remain in which the forceps could possibly have been implicated. Investigation of these, however, revealed in each case the presence of other concomitant and potentially lethal factors, none of which could be completely ruled out as the primary cause of fetal death. Each of the three cases is discussed in detail. We conclude from our series that the Shute forceps is useful in the delivery of premature infants, but should be employed for this maneuver only by very experienced operators. In these cases, midforceps should be performed only for critical indications. The risk of damage with parallel forceps deliveries from the pelvic floor is minimal if decision for operation is based on cardiotocographic criteria, and under favorable degrees of oxygenation. In the delivery of the immature infants, the parallel forceps can, in fact, hardly be superseded by any other instrument because of its unique controlled protection of the fragile fetal head from even the pressures of the birth canal. Delivery with the Shute forceps can be performed effectively under pudendal block or local infiltration anesthesia.
对10年间使用舒特平行产钳进行的1503例阴道分娩的器械损伤风险进行了分析。在这一系列病例中,有35例婴儿在分娩期或新生儿期死亡。排除所有与产钳无关的死因后,仍有3例可能与产钳有关。然而,对这些病例的调查显示,每例都存在其他伴随的潜在致命因素,没有一个因素可以完全排除作为胎儿死亡的主要原因。对这3例病例逐一进行了详细讨论。我们从本系列病例得出结论,舒特产钳对早产儿分娩有用,但仅应由经验非常丰富的操作人员用于此操作。在这些情况下,中位产钳术仅应在关键指征时进行。如果根据胎心监护标准并在有利的氧合程度下决定手术,盆底平行产钳分娩的损伤风险极小。在未成熟婴儿的分娩中,由于平行产钳对脆弱胎儿头部具有独特的控制性保护作用,可使其免受产道压力的影响,实际上几乎没有任何其他器械可以取代它。使用舒特产钳可在阴部阻滞或局部浸润麻醉下有效进行分娩。
