Four patients developed penile erection when regional anaesthesia was induced with spinal block. In another patient, penile erection developed during fentanyl-induced general anaesthesia. Injection of metaraminol into corpus cavernosum successfully achieved detumescence in all these patients. The dose of metaraminol ranged from 10 to 25 micrograms, much less than that required for the treatment of vasodilator-induced priapism. Intracavernosal injection of metaraminol is a simple, effective and safe method for immediate relief of intraoperative penile erection. It is most useful when urogenital operation would be delayed by penile tumescence.
4例患者在腰麻诱导区域麻醉时出现阴茎勃起。另有1例患者在芬太尼诱导的全身麻醉期间出现阴茎勃起。向海绵体内注射间羟胺成功使所有这些患者阴茎消肿。间羟胺剂量为10至25微克,远低于治疗血管扩张剂所致阴茎异常勃起所需剂量。海绵体内注射间羟胺是一种简单、有效且安全的方法,可立即缓解术中阴茎勃起。当泌尿生殖手术因阴茎肿胀而延迟时,该方法最为有用。
