[Outpatient or short-stay videothoracoscopy-assisted thoracic sympathectomy: anesthesia in 445 cases].

OBJECTIVE

To demonstrate the safety of outpatient or short-stay bilateral videothoracoscopy-assisted thoracic sympathectomy.

PATIENTS AND METHODS

The medical records of 445 who underwent bilateral videothoracoscopy-assisted thoracic sympathectomy were reviewed; the same protocols were used to guide these outpatient or short-stay procedures in all cases. Intravenous anesthesia was provided. An orotracheal tube allowed for carrying out the sympathectomy procedure during short periods of apnea. A 2% lidocaine solution was infused through the thoracic drains, which were removed soon after surgery. Data on intraoperative respiratory variables, pain, and intra- and postoperative complications were gathered. The data for patients undergoing the procedure on an outpatient or short-stay basis were compared.

RESULTS

No significant differences in demographic or perioperative variables were found between the 2 groups. In 3.6% of the patients in the series, there was a record of a postoperative pulmonary complication: 4 therapeutic minithoracotomies; 1 subcutaneous emphysema without radiologic changes; 9 residual pneumothoraces, 2 requiring pleural drainage; 1 chylothorax; and 1 delayed hemothorax. With the exception of the late-developing hemothorax, all complications were diagnosed and treated in the immediate postoperative period. In the outpatient surgery group, unplanned admissions because of patient refusal to leave occurred in 6.5% of the cases.

CONCLUSION

The low incidence of complications, and especially the finding that complications are detected in the early recovery period, indicate that this procedure can be performed on an outpatient basis.
