Examination at 18 months post-term of 139 infants of birth weight less than or equal to 1,500 gm revealed 18 instances (13%) of persistent median nerve damage. All affected infants had received frequent percutaneous brachial artery punctures as neonates. Block sections of the cubital fossa done at autopsy on 12 randomly selected very low-birth-weight infants showed perineural hemorrhage, and Wallerian degeneration or traumatic neuroma of the median nerve in eight patients. It is recommended that brachial artery punctures be avoided whenever possible in the neonatal period.
对139名出生体重小于或等于1500克的足月后18个月婴儿进行检查，发现18例（13%）持续性正中神经损伤。所有受影响婴儿在新生儿期均频繁接受经皮肱动脉穿刺。对12例随机选择的极低出生体重婴儿进行尸检时，对肘窝进行的阻断切片显示，8例患者存在神经周围出血、正中神经华勒氏变性或创伤性神经瘤。建议在新生儿期尽可能避免肱动脉穿刺。
