Comparative Study
Thoracic epidural anesthesia improves outcome after breast surgery.
The authors' objective was to compare the outcomes, including the incidence of nausea and vomiting and the time until discharge to home, of patients undergoing general anesthesia and thoracic epidural anesthesia for oncologic breast procedures. ⋯ Thoracic epidural anesthesia is a safe technique not associated with neurologic or respiratory complications. The use of thoracic epidural anesthesia for breast surgery could improve patients recovery and reduce the cost of these procedures.

Review Comparative Study
Recovery advantages of regional anesthesia compared with general anesthesia: adult patients.
The data support but do not conclusively prove, that RA results in a superior recovery compared with GA. However, several questions need to be answered. ⋯ Anesthetic techniques need to be carefully compared to determine whether they are equal in quality, efficiency, and cost. Finally, to determine whether RA is cost-effective, future studies involving ambulatory patients with a focus on outcome and well-being need to be conducted.

Comparative Study
Evaluation of the Pneupac Ventipac portable ventilator: comparison of performance in a mechanical lung and anaesthetized patients.
The performance of the Pneupac Ventipac portable gas-powered ventilator was evaluated in two stages. The accuracy of delivery of the ventilator was assessed using a mechanical lung model at different combinations of compliance and airway resistance to simulate normal and diseased lungs. The performance of the ventilator was then assessed in 20 anaesthetized patients. ⋯ Delivered tidal volume was between -19 and +12% of the present tidal volume in the group of anaesthetized patients using the ventilator in airmix mode. The ventilator was reliable and simple to use, and performance was within acceptable limits in the anaesthetized patients. However, we recommend that a means of verifying the adequacy of ventilation should always be used when transporting critically ill or anaesthetized patients with any portable ventilator, particularly when lung compliance or airway resistance may be abnormal.

Randomized Controlled Trial Comparative Study Clinical Trial
Assessment of recovery following day-case arthroscopy. A comparison between propofol and isoflurane-based anaesthesia.
Fifty healthy patients, aged 15-45 years, undergoing day-case arthroscopy, participated in a study to assess aspects of recovery and mood. Psychomotor tests, including the p-deletion test and the Trieger dot test, were performed pre-operatively and mood was measured using the mood adjective checklist. Anaesthesia in all patients was induced with propofol and a laryngeal mask airway was inserted immediately. ⋯ The time to discharge was similar in both groups as was the incidence of side effects. There was no difference in mood scores between the groups either at the time of discharge or at 24 h. We conclude that psychomotor recovery is somewhat quicker when isoflurane-based anaesthesia is used for day-case arthroscopy, but other factors, including time to awakening, mood and time to discharge are similar for both techniques.
