用等离子体原子发射光电直读光谱仪 ,检测 4 6例足月妊娠孕妇产时血清钙、镁、锌含量 ,并分析其与宫缩的关系。结果显示 ,继发性宫缩乏力组 (继发乏力组 )血清锌含量显著低于对照组 (宫缩正常组 ) ,P<0 .0 0 5;原发性宫缩乏力组 (原发乏力组 )潜伏期≥ 8小时者血清锌含量显著低于宫缩正常组潜伏期 <8小时者 (P<0 .0 5) ;血清镁含量 :继发乏力组 <宫缩正常组 <原发乏力组 ,其中继发乏力组与原发乏力组比较有显著差异 (P<0 .0 5) ;产时孕妇平均血清钙水平依次为宫缩正常组 >原发乏力组 >继发乏力组 ,但无统计学差异 (P>0 .0 5)。提示产时孕妇血清锌含量低可导致宫缩乏力 ;血清镁含量适当有利于正常宫缩 ,血清钙含量低可能是宫缩乏力的原因之一。
Plasma and atomic emission spectrophotometer was used to detect the serum levels of calcium, magnesium and zinc in 46 pregnant women during term pregnancy, and to analyze their relationship with uterine contractions. The results showed that the serum levels of zinc in secondary uterine atony group (secondary weakness group) were significantly lower than those in control group (normal contractions group), P <0.05. The primary uterine atresia group Group), serum zinc level was significantly lower than that of the normal contractions group (<8 h) (P <0.05); Serum magnesium content: the secondary weak group primary weakness group> secondary weakness group, but no statistics Learning difference (P> 0.05). Tip low maternal serum zinc levels during pregnancy can lead to uterine atony; serum magnesium appropriate to normal contractions, low serum calcium may be one of the causes of uterine atony.
