Transient aphonia following spinal anesthesia during emergency cesarean section: Case report and review of literature.

Abstract

Subarachnoid block with local anesthetic agents is a well-established anesthesia technique among pregnant females for labor analgesia and cesarian delivery. Although it is considered a reliable and safe technique for both mothers and fetuses, unexpected high or low levels of block may occur due to accidental injection of these agents into different meningeal spaces other than intended. Hypotension, bradycardia, headache, and failed anesthesia are common complications of spinal anesthesia. Though rare, neurological complications like aphonia, dysphagia, and tingling sensation have also been reported. The article reports a case of a 22-year-old primigravida who sustained transient aphonia following intrathecal administration of bupivacaine for an emergency cesarian section for meconium-stained liquor with fetal distress. There were no other neurological manifestations or features suggestive of high spinal block. The sensory level of the block was fixed to T6 with hemodynamic stability throughout aphasia with an episode of hypotension preceding aphonia. Aphonia commenced 9 min after the spinal anesthesia continued for a total duration of 15 min. Neurological examination, relevant investigations, and consultations were done to make a diagnosis. Thus, it is important to be aware of the possible neurological complications associated with spinal anesthesia.
