- Allergic reactions
- Cardiac complications
- Unexpected surgical events
How an Anesthetist Works
Anesthesia Delivery
Depending on qualifications and regulations, anesthetists may:
- Administer anesthesia
- Monitor patients
- Assist anesthesia teams
- Support surgical procedures
Team Based Care
Many healthcare systems use anesthesia care teams that include:
- Anesthesiologists
- Nurse anesthetists
- Anesthesia assistants
- Surgical staff
Teamwork improves efficiency and patient care.
Difference Between Anesthetist and Anesthesiologist in Real Life
