Transient radicular irritation after hyperbaric lidocaine spinal anesthesia in parturients.
Two cases of transient radicular irritation in pregnant patients are presented. Both cases involve the combination of spinal anesthesia employing hyperbaric 5% lidocaine and a small gauge pencilpoint needle as well as the surgery being performed in the lithotomy position. We recommend that until the potential for lidocaine-induced neuroradicular irritation under these circumstances is evaluated prospectively, hyperbaric lidocaine should not be used for cases in which a small gauge spinal needle is employed and the patient is placed in the lithotomy position.
