Stab wounds can cause various internal and external injuries. They are generally caused by low-velocity weapons, meaning the injuries inflicted on a person are typically confined to the path it took internally, instead of causing damage to surrounding tissue, which is common of gunshot wounds.[6] The abdomen is the most commonly injured area from a stab wound. Interventions that may be needed depending on severity of the injury include airway, intravenous access, and control of hemorrhage.[5][7] The length and size of the knife blade, as well as the trajectory it followed, may be important in planning management as it can be a predictor of what structures were damaged.[1][3] There are also special considerations to take into effect as given the nature of injuries, there is a higher likelihood that persons with these injuries might be under the influence of illicit substances which can make it harder to obtain a complete medical history.[8] Special precautions should also be taken to prevent further injury from a perpetrator to the victim in a hospital setting.[9] Similarly to treating shock, it is important to keep the systolic pressure above 90mmHg, maintain the person's core body temperature, and for prompt transport to a trauma center in severe cases.[10][11]
