The effect of early ambulation on the incidence of neurological complication after spinal anesthesia with lidocaine

Background: Transient neurological symptoms (TNS), was described in patients recovering from spinal anesthesia with lidocaine but its etiology remains unknown this study was evaluated the influence of ambulation time on the occurrence of TNSs after spinal anesthesia with lidocaine 5%. Materials and Methods: This randomized clinical trial was conducted on 60 patients with American Society of Anesthesiologists Grades I and II, who were candidates for lower abdominal surgery in supine or lithotomy positions. Patients were randomly divided into early ambulation group (Group A) who were asked to start walking as soon as the anesthesia was diminished or to the late ambulation group (Group B) who walked after at least 12 h bedridden. Participants were contacted 2 days after spinal anesthesia to assess any type of pain at surgical or anesthesia injection site, muscle weakness, fatigue, vertigo, nausea, vomiting, headache, and difficult urination or defecation. Results: Four subjects (13.3%) in Group A and two patients (6.7%) in Group B had pain at anesthesia injection site (P = 0.019). Fourteen patients in Group A (46.7%) and six patients in Group B (20%) had post-dural puncture headache (P = 0.014). Participants in Group B reported difficult urination more than Group A (P = 0.002). there were not statistically significant differences between two groups regarding frequency of fatigue, muscle weakness, vertigo, nausea, vomiting, difficult defecation, paresthesia, and the mean of visual analogue scale at the surgical site. Conclusion: Early ambulation after spinal anesthesia with lidocaine did not increase the risk of neurologic complication.
