About Us

Your Full-Service Anesthesia Partner

Twin Anesthesia is an anesthesia practice dedicated to safe, effective anesthesia services performed by Certified Registered Nurse Anesthetists (CRNAs).

Twin Anesthesia CRNAs have full clinical autonomy and professional responsibility. Unlike the anesthesia care team (ACT) model, Twin Anesthesia encourages CRNAs to utilize their full skill set and places no limits on scope of practice. Twin Anesthesia also offers providers the unique opportunity to partner in the practice. Both attributes make Twin Anesthesia an ideal place to work, and attract strong CRNAs that are invested in the company.  This independent practice model has allowed Twin Anesthesia to grow at a rapid rate even in the face of an anesthesia provider shortage. When you work with Twin Anesthesia you can be assured you will be working with the best anesthesia providers available. 

 We look forward to hearing how we can assist you.

What is a Certified Registered Nurse Anesthetist?

CRNAs are Registered Nurses who have graduated with a master’s or doctoral degree in nurse anesthesia. Most have significant experience in adult and/or pediatric critical care before attending a graduate program. During their graduate programs, they spend 24 to 36 months studying pathophysiology, anatomy, pharmacology, physics, and clinical anesthesia, followed by years of hospital and clinic-based anesthesia training, often resulting in over 2,500 hours of anesthesia time and 1,000 anesthetic cases completed.

Upon completing their degree, they must be qualified with the National Board of Certification and Recertification of Nurse Anesthetists (NBCRNA) to take an official board examination. Upon passing the examination, they become board-licensed as a CRNA and Advanced Practice Registered Nurse (APRN). In Minnesota, an “opt-out” state, CRNAs are not legally required to be supervised by a physician anesthesiologist to practice.

In military, clinic, and hospital settings, CRNAs are very often the only anesthesia providers. In a large majority of rural settings, CRNAs are the sole anesthesia providers. Nurse Anesthetists perform over 34 million anesthetics per year in the United States, according to the AANA 2012 Practice Profile Survey. CRNAs also follow the same American Society of Anesthesiologists (ASA) guidelines that physician anesthesiologists follow.

They also maintain the same certifications that physicians do for emergency resuscitation, such as Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), and Pediatric Advanced Life Support (PALS). Therefore, in all care settings, CRNAs are qualified to provide local, regional, sedation, and general anesthesia for patients of all ages.

Certified Registered Nurse Anesthetists (CRNAs) are anesthesia specialists who administer approximately 65 percent of all anesthetics given to patients in the United States each year. CRNAs represent a commitment to high standards in a demanding field. The educational requirements to become a CRNA are extensive. Prior to applying for admission to a graduate program in nurse anesthesia, a candidate must have a four-year Bachelor of Science degree in nursing or another appropriate baccalaureate degree, a current license as a registered nurse, and a minimum of one year’s acute care nursing experience. The master’s degree in nurse anesthesia program itself is 24-36 months, depending on university requirements. CRNAs are board-certified, and mandatory continuing education is required for recertification every two years. Nurse anesthetists provide high-quality anesthesia services combined with personal concern for the health and welfare of patients. They are happy to assist you and offer information about what to expect with your anesthesia.
