Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Comprehensive care of victims of sexual assault must address both acute medical and psychosocial needs of the patient and must happen in concert with forensic and legal requirements. Ideally, this care is provided by a specially trained sexual assault examiner when available. Thorough collection and preservation of all potential evidence and careful documentation of any physical findings are imperative. Chain of custody must be established and maintained for all samples collected in order for them to be used in later legal proceedings. Meticulous general and genital examination may reveal injuries to the perineum, rectum, vaginal fornices, vagina, and cervix as well as associated injuries to other areas of the body. Toluidine staining and colposcopy are useful in enhancing less apparent injuries such as those to the posterior fourchette and perianal area. Tears to the posterior fourchette are most commonly found in the distribution between the 3- and 9-o’clock positions when the patient is examined in dorsal lithotomy. Perianal lacerations are more evident with toluidine staining and appear as linear tears.
