* The Use of Advanced Regional Anesthesia for Ambulatory Surgery:
The unique use of single injection and continuous peripheral nerve blocks has tremendous advantages for outpatients. This is the major focus of the textbook " Ambulatory Anesthesia and Perioperative Analgesia" (Editors Susan M. Steele, Karen C. Nielsen, Stephen M. Klein).

* Ambulatory Anesthesiology Database:
The ambulatory anesthesia database collects outcomes data for regional and ambulatory anesthesia. This database has proved that valuable data can be collected in an ambulatory setting resulting in continuous quality improvement, providing improved support for research and publications.

* Continuous Peripheral Nerve Blockade in the Ambulatory Setting:
Major surgical procedures on healthy and high risk patients (ASA III and IV) can be performed in an ambulatory setting due to continuous regional anesthetic techniques.

* Continuous Peripheral Nerve Blockade in the Home Setting:
Major surgical procedures can be performed in an ambulatory setting under continuous peripheral nerve blocks. Patients can be discharged on the same day of surgery with disposable infusion pumps connected to peripheral nerve catheters for 3 -4 days. Patient selection and education are critical for the success of this home catheter program. Close patient follow-up is performed via telephone calls. Excellent pain management has been achieved, with improved cognitive function and sleep profile. No complications have been reported.

* The Use of Paravertebral Somatic Nerve Blockade Technique for Breast Cancer Surgery:
Benefits of regional anesthesia for breast cancer treatment include excellent analgesia, decreased incidence of postoperative nausea and
vomiting, faster recovery, preservation of immunologic function, decreasing hospital stay, and generating cost savings. Continuous paravertebral block techniques have been used to extend postoperative analgesia.
