Introduction: Most anesthesiologists use the thoracic epidural, with a 0.75% incidence of accidental perforation. However, they are reluctant to consider higher levels for spinal anesthesia because of the possibility of direct spinal cord injury. The main objective of this retrospective study was to evaluate the incidence of paresthesia and neurological complications, as well as cardiocirculatory changes after thoracic spinal anesthesia. Methods:We conducted a retrospective audit, between January 2007 and December 2019. We reviewed the record sheets of patients who experienced paresthesia for thoracic spinal anesthesia with two types of needles of the same gauge, isobaric and hyperbaric 0.5% bupivacaine and puncture in the sitting or left lateral position, and median and paramedian insertion.Results: Paresthesias occurred in 5.9% of patients. 41 patients experienced a paresthesia with cut needle compared with 43 patients with pencil point, without statistical difference. All paresthesias were transient, and lasted a maximum of three days. No sequelae neurologic were observed in all patients during this study. Bradycardia occurred in 3.1% of the patients and hypotension in 13.2% of the patients, easily corrected by the use of atropine and vasopressor. Conclusion:All 84 paresthesias observed in this study were associated with free flow of CSF when the stylet was removed from the needles. An association was not found between the type of the spinal needle and the incidence of paresthesias. This study with 1,406 patients showed that thoracic spinal anesthesia is safe and without neurological sequelae, with a puncture between T8 and T11.
