Transient Neurologic Toxicity After Hyperbaric Subarachnoid Anesthesia with 5% Lidocaine

Complicações neurológicas determinadas pela anestesia subaracnóidea

“…Descritos por Schneider e col. em 1993 66 , os sintomas neurológicos transitórios (SNT) caracterizam-se por dor nas costas, que se irradia para as nádegas e face dorso-lateral das pernas, bilateralmente, sendo restrita aos dermátomos L 5 -S 1 , às vezes acompanhada por disestesias. Esta dor inicia-se nas primeiras 24 horas que seguem a regressão da anestesia subaracnóidea (tempo que pode variar de 1 a 20 horas) sempre após período livre de sintomas 66,67 .…”

“…Esta dor inicia-se nas primeiras 24 horas que seguem a regressão da anestesia subaracnóidea (tempo que pode variar de 1 a 20 horas) sempre após período livre de sintomas 66,67 . Ador, na maioria dos casos, é de moderada intensidade, com duração média de 2 a 3 dias.…”

“…Described by Schneider et al 66 in 1993, transient neurological symptoms (TNS) are characterized by back pain irradiating to the buttocks and legs dorsolateral face bilaterally, being restricted to dermatomes L 5 -S 1 , sometimes followed by dysesthesias. Pain starts within 24 hours after spinal anesthesia recovery (varying from 1 to 20 hours) always after a period without symptoms 66,67 .…”

Neurotoxicity of lidocaine — does it exist?

“…This has been accompanied by increased reporting of neurological complications, in particular following continuous 1,2 and single injection 3,4 spinal anaesthesia with hyperbaric 5% lidocaine. 3,4 This issue of the Journal contains another report of transient neurological problems associated with the single injection of hyperbaric lidocaine for spinal anaesthesia. 5 Before there is widespread condemnation of lidocaine, one has to examine all of the possible variables critically: drug, technique, patient selection.…”
