The formalin-based method of embalming is the most common procedure employed for the preservation of cadavers in most medical schools of South Asia. The adequacy of perfusion of formalin through the cadaveric tissues would aptly mark the time of completion of embalming. However, there is currently no objective evidence to justify the endpoint of perfusion in embalming. This study addressed the aforementioned problem by utilizing cadaveric thumb fingerprints coated with a modified iodine-based solution that indicated the completion of perfusion during embalming.
Cadaveric thumb fingerprints and thumb nail plates coated with a modified solution of iodine offered a medium wherein the color changes of perfusion were observed from pale brown to colorless.
The color changes at the fingerprints and nail plates coincided with the onset of lip stiffness and confirmed the completion of perfusion based on their consistency in all the cadavers.
The iodine-based method of color change could definitely serve as a marker of perfusion during embalming.
在南亚大多数医学院校，基于福尔马林的尸体防腐方法是保存尸体最常用的程序。福尔马林在尸体组织中的灌注充分程度将恰当地标志着防腐处理的完成时间。然而，目前尚无客观证据来证明防腐处理中灌注终点的合理性。本研究通过利用涂有改良碘基溶液的尸体拇指指纹来解决上述问题，该溶液可指示防腐处理过程中灌注的完成情况。
涂有改良碘溶液的尸体拇指指纹和拇指甲板提供了一个介质，在其中可观察到灌注时颜色从浅棕色变为无色的变化。
指纹和指甲板处的颜色变化与嘴唇僵硬的开始时间一致，并基于所有尸体中的一致性证实了灌注的完成。
基于碘的颜色变化方法肯定可以作为防腐处理过程中灌注的标志物。
