Wrist cutting

Wrist cutting is sometimes practiced with the goal of self-harm and not suicide; however, if the bleeding is copious or allowed to continue unchecked, cardiac arrhythmia, followed by severe hypovolemia, shock, circulatory collapse or cardiac arrest, and death may ensue, in that order.[2]

In the case of a failed suicide attempt, the person may experience injury of the tendons of the extrinsic flexor muscles, or the ulnar and median nerves which control the muscles of the hand, both of which can result in temporary or permanent reduction in the victim's sensory or motor ability or also cause chronic somatic or autonomic pain.[3] As in any class IV hemorrhage, aggressive resuscitation is required to prevent death of the patient; standard emergency bleeding control applies for pre-hospital treatment.
