Module 2 - Week 2 Flashcards
What are the two main categories of perioperative team members?
Sterile and non-sterile team members.
Who are the sterile team members in the OR?
Surgeon, surgical assistants, and scrub nurse.
Who are the non-sterile team members in the OR?
Anesthesiologist, circulating nurse, MRTs, technologists, and sales/service reps.
What is the role of the surgeon in the OR?
Leads the procedure and makes critical decisions.
What does the scrub nurse do?
Maintains the sterile field, passes instruments, and assists the surgeon.
What does the circulating nurse do?
Ensures proper equipment and supplies, maintains sterile techniques, and assists patient care.
What does the anesthesiologist do?
Manages anesthesia, monitors patient vitals, and ensures patient stability.
What is the sterile field in the OR?
The immediate area around the patient where only sterile personnel and instruments are allowed.
What are common imaging devices used in the OR?
Portable X-ray, Mini C-Arm, Conventional C-Arm, CT, MRI, and hybrid systems.
What are the three OR zones?
Unrestricted (Zone 1), Semi-Restricted (Zone 2), Restricted (Zone 3).
What happens before surgery?
Pre-admission tests, anesthesia consultation, and surgical site marking.
What happens during surgery?
Patient is transferred to OR, anesthesia is administered, and surgery is performed.
What happens after surgery?
Patient is moved to the PACU, monitored for complications, and may receive post-op imaging.
What does an MRT do in the OR?
Sets up and operates imaging equipment, maintains sterile techniques, and ensures radiation safety.
How can radiation exposure be minimized in the OR?
Use lead aprons, shields, minimize exposure time, and monitor fluoroscopy use.
What signs indicate a reaction to anesthesia?
Dizziness, light-headedness, low blood pressure, airway obstruction, and seizures.
Why is post-operative imaging important?
It verifies surgical success, such as implant placement in orthopedic cases.
Why must imaging equipment be cleaned before re-use in the OR?
To prevent contamination and maintain a sterile environment.
What is a hybrid OR system?
An OR with multiple imaging modalities, like CT, MRI, and angiography, integrated for complex surgeries.
What is fluoroscopy used for in surgery?
Real-time imaging during orthopedic, cardiac, and abdominal procedures.
What must an MRT do before surgery begins?
Ensure equipment is clean and charged, verify patient identity, and confirm proper protective gear is worn.
What is the Mini C-Arm used for?
Imaging small joints in hand, wrist, ankle, and foot surgeries.
Why is traffic control important in the OR?
To reduce contamination and maintain a sterile environment.
Why are CT and MRI used in the OR?
For precision in complex procedures like neurosurgery and spinal surgeries.
What must an MRT do after surgery?
Clean imaging equipment, send images to PACS, and document procedure details.
