Abdominal Stab WoundsThe severity of stab wounds is based exclusively on the location and depth of penetration. Important considerations include the type of weapon used (knife length, shape, straight or serrated), and manner of assault (overhand vs.underhand). The gender of the assailant may have some importance, in that women tend to stab "overhand." Penetration tends to be deeper with the "underhand" thrust. ALL STAB WOUNDS REQUIRE IMMEDIATE PHYSICIAN MANAGEMENT. All stab wounds require a tetanus vaccination within the past 5 years. Stab wounds to the CHEST should always be considered LETHAL until proven otherwise. Chest wounds can result in rupture of the lung (pneumothorax) or marked bleeding within the chest cavity (hemothorax). Central stab wounds, below the collar bones (clavicles) and to either side of the breastbone (sternum), can result in penetration of the heart. Remember, the ability to penetrate the heart is limited by the length of the knife and the force exerted by the assailant. Stab wounds to the ABDOMEN always require EMERGENCY evaluation. These injuries will often result in an exploratory laparotomy (operation) to rule out serious damage. Slow bleeding inside the abdomen is extremely difficult to diagnose, and should be considered a possibility in every case. Wounds that have internal organs passing through the opening (evisceration) require prompt Stab wounds to the upper back can involve the lung or heart. Stab wounds to the lower and middle back can involve the kidneys and/or ureters. Evaluation of stab wounds to the back that may have punctured the kidney will require intravenous pyelography for evaluation. The presence of blood in the urinalysis indicates injury to the kidney, bladder, or ureter. Stab wounds to the EXTREMITIES that do not lacerate nerves, blood vessels, or tendon structures, often can be sutured closed loosely, or left open to heal on their own. Cases where vascular injury is a possibility, may require angiography to determine if operative intervention is necessary. Examination In short, all stab wounds are potentially SERIOUS injuries that require the evaluation by a qualified Emergency Physician.Consultation to the General Surgeon will be made where appropriate.
