Cervical epidural anesthesia using 300 mg lidocaine results in measurable reduction in bedside pulmonary functions concomitant with the spread of analgesia to the C3 dermatome. These changes were complete 20 minutes after lidocaine injection. In patients without preexisting lung disease, these changes were not clinically significant, except in one patient. We conclude that motor block of the phrenic nerve is incomplete under the conditions of this study.
The authors describe the occurrence of severe postoperative pain and long thoracic nerve injury after Port-Access minimally invasive mitral valve surgery. The potential for these events and the impact on postoperative hospitalization and rehabilitation are emphasized.
