１９９２～１９９３年间随机选择无严重并发症产妇１１８例，观察分娩前输注不同浓度葡萄糖及晶体液对胎儿脐动、静脉血气分析的影响，输液速度以葡萄糖４０ｇ／３０ｍｉｎ及２０ｇ／３０ｍｉｎ为实验组，同样容量的晶体液为对照组，结果发现输糖４０ｇ的剖宫产组脐动脉血ｐＨ为７．１９，明显低于对照组，输糖量≤２０ｇ及输复方乳酸钠溶液的剖宫产组脐动脉血ｐＨ＞７．２０，而输２０ｇ糖的阴道分娩组脐血ｐＨ为７．１７，其他血气指标显示了混合性酸中毒。本实验说明高糖溶液分娩前输入可致亚临床酸血症。因此必需输葡萄糖时应＜０．５ｇ／ｋｇ·ｈ，长时间输液应＜１０ｇ／ｈ，并补充电介质及碱性液体。
From 1992 to 1993, 118 maternal women without serious complications were randomly selected. The effects of different concentrations of glucose and crystalloid before delivery on fetal umbilical arterial and venous blood gas analysis were observed. The infusion rates of glucose 40g / 30min and 20g / 30min were used as experimental group , The same volume of crystal fluid for the control group, found that 40g of glucose-induced cesarean section umbilical artery blood pH was 7.19, significantly lower than the control group, the amount of sugar infusion ≤ 20g and loser sodium lactate cesarean section Umbilical artery blood pH> 7.20, and lose 20g sugar vaginal delivery group cord blood pH was 7.17, other blood gas showed mixed acidosis. This experiment shows that high glucose solution before delivery can cause subclinical acidosis. Therefore, glucose must be lost when <0.5g / kg · h, long infusion should be <10g / h, and add the dielectric and alkaline liquid.
