Meniere-like syndrome following epidural morphine analgesia

Abstract

The demonstration that effective and prolonged pain relief can be achieved by injection of small doses of morphine into the epidural space has led to increasing use of epidural morphine analgesia by clinicians, particularly in obstetrics and gynecology. Side effects attributed to epidural morphine administration are common, some irritating, others dangerous. We report here an unusual side effect, a Meniere-like syndrome, that appeared 6 h after a second dose of epidural morphine and was successfully treated with naloxone.
