摘要

目的：评估心脏内注射氯化钾（KCl）对胎儿尸检时组织变性的影响，这可能有助于告知终止妊娠护理和尸检预期。研究设计：在这个有胎儿尸检的引产回顾性队列中（N=266），我们估计了KCl和胎儿组织变性之间的关系（嗜碱性粒细胞增多和嗜酸性粒细胞增多的定性评估和定量比例）。我们使用对数二项和线性回归计算风险比和95%置信区间的平均差异。结果：接受KCl治疗的患者比未接受KCl治疗的患者更容易发生定性组织变性（RR 2.8 [95% CI 1.3-6.1]）。定量嗜碱性粒细胞：嗜酸性粒细胞比例在KCl患者中较低（心脏组织的平均差异为-0.031 [95%CI -0.039至-0.023]），这进一步支持了这些病例中组织变性的增加。结论：引产胎儿解剖中注射KCl的胎儿与未注射KCl的胎儿相比，组织变性的风险增加。

Potassium chloride intracardiac fetal injection and tissue degeneration at fetal autopsy following induction abortion

Objectives

To assess the impact of potassium chloride intracardiac injection (KCl) on tissue degeneration at fetal autopsy, which may help inform termination care and autopsy expectations.

Study design

In this retrospective cohort of induction abortions with fetal autopsies (N = 266), we estimated the association between KCl and fetal tissue degeneration (qualitative assessment and quantitative ratio of basophilia:eosinophilia). We used log binomal and linear regression to calculate risk ratios and mean differences with 95% confidence intervals.

Results

Those who received KCl were more likely to have qualitative tissue degeneration than those who did not (RR 2.8 [95% CI 1.3–6.1]). Quantitative basophilia:eosinophilia ratios were lower among those with KCl (mean difference in cardiac tissues of −0.031 [95% CI −0.039 to −0.023]), which further supports increased tissue degeneration in these cases.

Conclusions

Fetal autopsies from induction abortions that had KCl fetal injection had increased risk of tissue degeneration compared with those that did not.
