The Gas Vas™ Nitrous Oxide

New Sedation Technique Used for Urology Procedures

Urologists in Scott & White's Division of Urology have a new tool to keep patients comfortable during procedures. Surgeons are now using The Gas Vas™ nitrous oxide analgesia to keep patients sedated during vasectomies and other procedures.

Until recently, mainly dentists have used nitrous oxide. But new research shows it can also be effective during some medical procedures. Scott & White urologists are the first in the United States to use it for urology patients.

"Urology procedures can be an uncomfortable and painful experience for the patient,"said Erin Travis Bird, MD, director for the Division of Urology. “We wanted to offer an alternative treatment in a clinic setting that would reduce pain and help patients recover faster after their procedure.”

By blending N2O with oxygen (O2) and administering it through a gas mixer system, patients can now receive pain relief quickly and simply in the clinic by breathing through a mask — no injections, atomizers, or IV infusions. The gas mixer system, called The Gas Vas™ system, can be used for minimal to moderate pain management in outpatient cases conducted outside the hospital operating room.

"Using this new system can be quicker and more cost effective to the patient," Dr. Bird said. "Operating room procedures are obviously more expensive and the prep and recovery time for the patient can take hours. Using this non-invasive procedure in the clinic means the patient recovers quicker and allows us to manage their pain while they are still awake."

While The Gas Vas™ system is not an option for all urology patients and procedures, it can be beneficial for some patients undergoing minor procedures. Talk to your doctor to see if it could be an option for you.
