- Inform the attending physicians of important intraoperative events that require his / her input or attention
- By working with several different senior residents and attendings, the resident will be exposed to a variety of styles, techniques, attitudes, and approaches to the safe administration of anesthesia. The resident must develop enough flexibility to deal with these differences.
PRACTICE-BASED LEARNING (See general competencies section)
In addition, the following specific competency must be developed:
- Blending of skills and knowledge discussed above resulting in a smooth, deliberate rhythm of perioperative routine patient care from preparation to induction to emergence to postoperative care. The resident will build on these skills to develop speed, efficiency and ability to handle more complex cases in the CA-2 and CA-3 years.
SYSTEMS-BASED PRACTICE (See general competencies section)
Evaluation to Determine Goal Achievement
- You are evaluated every week by all attendings who worked with you (contact-based online computer evaluation system). These evaluations are reviewed quarterly by the Clinical Competence Committee and continuously by the program director. Your advisor informs you of any problems identified, and serious problems will be discussed with you immediately after they occur.
- You will complete a Departmental Rotation Evaluation Form.
- The Residency Program Director will evaluate the results of the In-Training Examination for the
American Board of Anesthesiologists (ABA) for areas of departmental weakness. Consistent
weaknesses may result in adjustment of the above goals.Teaching Resources to Accomplish the Objectives

Goals and competencies for the resident rotating on the S2 or VA (CA-2) rotation are the same as described above with these additional competencies:
- Improved preoperative evaluation skills to consultant level by the end of the CA-2 year.
- The resident at the conclusion of the CA-2 year should be able to perform an anesthetic for any routine surgical procedure as well as uncomplicated subspecialty procedures with minimal direct input from the attending physician (this does not mean unsupervised - it means only that the resident should possess the necessary skills to conduct a safe, well-planned anesthetic on such a patient).
- The CA-2 level resident will be given more freedom to make management decisions during routine anesthetics. With the concurrence of the attending physician prior to starting the case, the CA-2 resident may make clinically indicated adjustments in perioperative management including but not limited to anesthetic technique (choice of drugs as well as techniques), ventilatory management, and fluid management.
- Become skilled in catheterizing or cannulating the following vessels for sampling blood, measuring
concentrations or pressures, or administering drugs or fluids:
- Veins: all age groups and all sizes, including sick children / neonates
- Arteries: radial and other sites
- Central vessels: internal jugular, subclavian, femoral, and "long-arm" routes
- Pulmonary artery (commonly)
- Become skilled in using and interpreting the following routine noninvasive and non-routine invasive monitors intraoperatively:
- Central venous pressure: values and waveform
- Pulmonary artery pressure: values and waveforms, pulmonary capillary wedge tracing
- Mixed venous oxygen saturation - significance of value and changes in value
- Cardiac output - thermodilution methods, continuous methods
- Electrophysiologic monitoring of the nervous system:
- EEG
- Somatosensory and auditory evoked potentials
- EMG
- Transesophageal Echocardiography (basic understanding only)
CA-3 Level Rotation Information
Goals and competencies for the resident rotating on the S3 or VA (CA-3) rotation are the same as described above with these additional competencies:
- A more extensive knowledge of surgical procedures, anesthetic considerations and techniques necessary for the management of patients undergoing procedures in the recognized subspecialties including neurosurgery, obstetrics, cardiovascular surgery, pediatric surgery (all subspecialties involving children), ambulatory anesthesia, and regional anesthesia.
- Through the process of being paired with beginning level residents, both in simple and complex cases, learn how to apply your knowledge and experience to the benefit of other, less experienced clinicians. Through this supervision / teaching of younger residents, the CA-3 resident will learn skills necessary to the supervision of and working with certified registered nurse anesthetists.
- Consultant level preoperative evaluation skills, including all types of anesthetics in all subspecialties.
- The CA-3 level resident will be given more freedom to make management decisions during both routine and complex anesthetics. With the concurrence of the attending physician prior to starting the case, the CA-3 resident may make clinically indicated adjustments in all aspects of perioperative management independently. The attending physician will maintain supervisory control, but using a hands-off approach except when otherwise required by the clinical condition of the patient.
- The resident at the conclusion of the CA-3 year should be able to perform an anesthetic for any routine surgical procedure as well as some complicated subspecialty procedures independently. The CA-3 resident should also be able to provide supervision / guidance to less experienced residents involved in general or subspecialty anesthesia rotations.
