This is done on either side. If this is not sufficiently effective, then cold normal saline may be injected and removed. Medications
If aspiration is not sufficient, a small dose of phenylephrine may be injected into the corpus cavernosum. Side effects of phenylephrine may include: high blood pressure, slow heart rate, and arrhythmia. If this medication is used, it is recommended that people be monitored for at least an hour after. For those with recurrent ischemic priapism, diethylstilbestrol (DES) or terbutaline may be tried. Surgery
Distal shunts, such as the Winters, involve puncturing the glans (the distal part of the penis) into one of the cavernosa, where the old, stagnant blood is held. This causes the blood to leave the penis and return to the circulation. This procedure can be performed by a urologist at the bedside. Winters shunts are often the first invasive technique used, especially in hematologically induced priapism, as it is relatively simple and repeatable.Proximal shunts, such as the Quackels, are more involved and entail operative dissection in the perineum where the corpora meet the spongiosum while making an incision in both and suturing both openings together. Shunts created between the corpora cavernosa and great saphenous vein called a Grayhack shunt can be done though this technique is rarely used.As the complication rates with prolonged priapism are high, early penile prosthesis implantation may be considered. As well as allowing early resumption of sexual activity, early implantation can avoid the formation of dense fibrosis and, hence, a shortened penis.
Sickle cell anemia
In sickle cell anemia, treatment is initially with intravenous fluids, pain medication, and oxygen therapy. The typical treatment of priapism may be carried out as well. Blood transfusions are not usually recommended as part of the initial treatment, but if other treatments are not effective, exchange transfusion may be done. History
Persistent semi-erections and intermittent states of prolonged erections have historically been sometimes called semi-priapism. Terminology
The name comes from the Greek god Priapus (Ancient Greek: Πρίαπος), a fertility god, often represented with a disproportionately large, permanent erection. References
