How does anesthesia work?

Preparing For Surgery
A vital part of providing you a safe anesthetic is how you prepare for your procedure the day before. We’ve provided this short list of information to help cover the basics of what you can expect. One of our anesthesia providers will be contacting you prior to your surgical date to cover your health history and address any questions or concerns you may have. If your concerns are pressing, please don’t hesitate to contact our office at: 503-548-4770 and we’d be happy to put you in touch with one of our clinicians quickly.
FOLLOW THESE 5 SIMPLE STEPS TO ENSURE YOUR SAFETY BEFORE SURGERY
- DO NOT EAT ANYTHING 8 HOURS PRIOR to your surgery.
- YOU MAY DRINK CLEAR LIQUIDS UP TO 2 HOURS PRIOR to your surgery admission time. This is very important! If you forget and do ingest something, your surgery may be cancelled, postponed or rescheduled.
- Please take routine morning medicines with a small sip of water. DIABETICS, please consult with your anesthesia provider prior to your date of surgery.
- Refrain from chewing gum or chewing tobacco the morning of surgery. If you are a smoker, do not indulge that morning.
- Contact lenses may be left in, but please inform your provider of their presence.
"We've carefully crafted our mission, vision and values to accurately reflect the culture of who we are. We believe this effort will provide an anesthesia experience that is well rounded on both a clinical and relational level, serving both our patients and our clients with the highest standards of care, compassion and service. It is my commitment that your interactions with our providers are consistent with those values, no matter who you work with."
