In this method, the scientist uses cotton swabs dipped into nitric or hydrochloric acid to wipe the palms and backs of hands. The seal is completed when the chest drain is inserted.

Inaba K, Demetriades D; The nonoperative management of penetrating abdominal trauma. By the mid 1980’s, scientists had come up with three generally accepted methods of analyzing gunshot residues- neutron activation, flameless atomic absorption spectrometry (FAAS), and scanning electron microscopic-energy dispersive x-ray spectrometry (SEM-EDX). Upgrade to Patient Pro Medical Professional? You are the best! The degree of tissue disruption caused by a projectile is related to the cavitation the projectile creates as it passes through tissue. The most important initial evaluation of a gunshot wound to the abdomen is whether there is uncontrolled bleeding, inflammation of the peritoneum, or spillage of bowel contents.
