An 18-year follow-up study was made of 62 males delivered by forceps and 38 by vacuum extraction in 1962-63. The obstetrical data are compared with the medical and psychological military draft board examinations. The mortality and morbidity rates were not significantly different from those of the total cohort of Norwegian conscripts, either in the forceps or in the vacuum group. Rotation of the fetal head with Kielland's forceps in midcavity extractions did not adversely affect the late results. A significantly elevated mean intelligence score was found in the forceps group, while the vacuum group did not differ from the national average.
对1962年至1963年间通过产钳分娩的62名男性和通过真空吸引分娩的38名男性进行了一项为期18年的随访研究。将产科数据与医学和心理征兵委员会的检查结果进行了比较。产钳组和真空吸引组的死亡率和发病率与挪威应征入伍者的总队列相比均无显著差异。在中骨盆牵引时使用基兰德产钳旋转胎头对后期结果没有不利影响。产钳组的平均智力得分显著升高，而真空吸引组与全国平均水平没有差异。
