Atypical Autoerotic Deaths

"Atypical" autoerotic deaths result from sexual stimulation by nonhypoxic mechanisms (about 10% [228,247,250,258,273]). These include:

Autoerotic Hanging

• Electrocution (228,229,238,247,250,286-289).

° Mechanisms of death can be multifactorial (273). Hypoxia can result from displacement of oxygen by gas (e.g., nitrous oxide, propane [247,261,268,273]). Some agents cause arrhythmia (e.g., trichloroethane, fluorocarbons [273,290]). Nitrates are associated with severe vasodilation (229,273). Other gases are central nervous systerm (CNS) depressants (e.g., tetrachloroethylene, gasoline [229,271]). These various inhalants are also used to commit suicide (291).

• Delayed death owing to bronchopneumonia secondary to renal failure from a urinary bladder calculus around a self-introduced catheter (292).

• Intrarectal wound caused by firearm (see Chapter 6, Heading 10).

Deaths from natural disease occurs during autoerotic practices (Fig. 49; refs. 226, 228, 243, 244, 250, and 276).
