Inadvertent intrathecal injection of labetalol in a patient undergoing post-partum tubal ligation

Int J Obstet Anesth. 2005 Oct;14(4):340-2. doi: 10.1016/j.ijoa.2005.02.005.


After receiving a continuous spinal anesthetic for labor following an inadvertent dural puncture with a 17-gauge epidural needle, a morbidly obese parturient underwent post-partum tubal ligation 12 h after vaginal delivery. The patient received a total of 2 mL of 0.75% hyperbaric bupivacaine for the surgery. In response to moderate hypertension the patient received intravenous labetalol hydrochloride 20 mg. She subsequently was inadvertently administered approximately 15 mg of labetalol through the spinal catheter. The spinal catheter was removed immediately after the procedure. She suffered no apparent adverse neurologic effects.
