Complete recovery from long-standing priapism in a stallion after propionylpromazine/xylazine sedation

Contemporary use of acepromazine in the anaesthetic management of male horses and ponies: A retrospective study and opinion poll

“…The terms priapism , penile prolapse or penile paralysis often have been used interchangeably although each term entails distinct features (Blanchard et al . 1991; Boller et al . 2005; McDonnell 2005).…”

“…These secondary pathological events most often cause irreversible damage to the penis and erectile dysfunction. They are hardly distinguishable from the sequela of true priapism (Boller et al . 2005).…”

“…benzatropine mesylate 16 µg/kg bwt) or irrigation of stagnant blood flow from the CCP with heparinised saline (with or without adrenaline) have been successful (Wilson et al . 1991; Boller et al . 2005; Pauwels et al .…”

“…It should be emphasised that priapism or penile prolapse has repeatedly been reported to resolve with treatment without need for penile amputation (Lucke and Sansom 1979; Gerring 1981; Sharrock 1982; Wilson et al . 1991; Nie and Pope 1997; Boller et al . 2005).…”

“…Administration of phenothiazines in the equine has long been associated with prolonged or persistent protrusion of the penis (Gross 2001;Muir 2009). The terms priapism, penile prolapse or penile paralysis often have been used interchangeably although each term entails distinct features (Blanchard et al 1991;Boller et al 2005;McDonnell 2005). Equine priapism has been defined as persistent penile erection without sexual stimulation due to a neuromuscular dysfunction, which is still poorly understood and may or not involve the autonomic nervous system and penile vascular bed (Pearson and Weaver 1978;Allen 1999;McDonnell 2005;Pauwels et al 2005).…”
