PREEXISTING NEUROLOGIC DISORDER TRIGGERED BY ANESTHESIA?

Neurologic deficits appearing after various anesthetic techniques are not always caused by these procedures, also some are attributed to them. Neuraxial blocks - spinal, more often than epidural - have been associated with the postoperative relapse of multiple sclerosis, although the evidence is not strong. The mechanism is unknown but it is speculated that the disease makes the spinal cord more susceptible to the neurotoxic effects of local anesthetics. We present the case of 42-years-old female, scheduled for ureteroscopy for ureteric calculi under spinal anesthesia. Postoperatively she developed various neurological symptoms that together with the paraclinical findings led to the diagnosis of multiple sclerosis. [ABSTRACT FROM AUTHOR]
