Despite extensive media coverage of the threat of chemical and biological weapons, Americans are more likely to be injured in attacks with conventional explosives, claimed Pascal O. Udekwu, MBBS."You must be involved in the disaster planning process at your hospital so that you can best care for and save as many of these people as possible," stressed Dr. Udekwu, an Associate Professor of Surgery at the University of North Carolina in Raleigh.
Initially, the blast from a conventional explosive is most likely to damage the ears, gastrointestinal tract, and respiratory tract.Further trauma often occurs from burns and from propelled debris, such as dirt, stones, other natural material, shell casings, and body parts.
"In addition to the standard acute lung injury, you can also have significant air embolism," Dr. Udekwu warned.Bronchoscopy may reveal large air leaks; it can also be used to guide the surgical repair of such leaks.
Quick action may be necessary to provide an airway for those with severe respiratory distress, said Dr. Udekwu.He suggested conventional mechanical ventilation in these cases because "pulmonary injuries can be rapidly progressive" and lead to death.
Notably, blast victims may present with colonic perforation that must be found early to prevent sepsis."Perforated hollow viscous or other injuries will have a significant impact on morbidity and mortality in these patients after you have managed their initial airway and oxygenation issues," Dr. Udekwu noted.
