Differences in serum glucose values obtained from different extremities in newborns with umbilical artery catheters (UAC) through which a dextrose solution was administered were studied. Control infants (n = 20) had no difference in simultaneous capillary glucose values obtained from both lower extremities. Infants with a low UAC had a significant difference between two (both lower extremities) or three (both lower and one upper extremity) simultaneous capillary glucose values. Infants with a high UAC did not. In the low UAC group, the serum glucose value was highest in the lower extremity through which the UAC entered the aorta and lowest in the upper extremity. The elevation in glucose value was related to the glucose infusion rate corrected for infant size (mg/kg/min). Clinicians caring for infants with low UACs should be aware of this potential error in order to prevent erroneous decision-making.
对通过脐动脉导管（UAC）输注葡萄糖溶液的新生儿不同肢体所测得的血糖值差异进行了研究。对照组婴儿（n = 20）双下肢同时测得的毛细血管血糖值无差异。UAC位置较低的婴儿，双下肢或双下肢及一个上肢同时测得的毛细血管血糖值之间存在显著差异。UAC位置较高的婴儿则无此差异。在UAC位置较低的组中，UAC进入主动脉的下肢血糖值最高，上肢血糖值最低。血糖值的升高与根据婴儿体重校正后的葡萄糖输注速率（mg/kg/分钟）有关。照顾UAC位置较低婴儿的临床医生应意识到这种潜在误差，以防止做出错误的决策。
