Doing well in a Cardiothoracic Surgery Rotation

Many times, third-year medical students will have to spend a portion of their required surgical clinical clerkship on Cardiothoracic Surgery. This portion of your surgery clerkship can provide a good informational background for anyone going into medicine, pediatrics or surgery. For the medicine, emergency medicine and anesthesia folks, you get first hand experience with the actions of pressors such as dopamine and dobutamine and other cardio pharmaceuticals in the postop management of these patients. You see the real-time effects of agents like nipride and nitroglycerine because most cardiac surgery patient will have pulmonary artery catheters in place in the immediate post-operative period. For those anticipating entering pediatrics, you will get a chance to see some of the effects of the congenital heart disease entities and how repairs are undertaken. For those entering the surgical specialties, you can develop an understanding of some specialized surgical techniques in addition to becoming familiar with the surgical intensive care unit.

Approaching the Rotation

The first step in any clinical rotation is to have good reference materials so that you understand the language that these surgeons will be using. For cardiothoracic surgery, I strongly recommend the following: Essentials of the Surgical Subspecialties by Lawrence, Cardiac Surgery Secrets by Solotoski or Handbook of Patient Care in Cardiac Surgery by Vlahakes. Any of these books will provide a solid background into the types of pathology that you will encounter in your rotation. The Lawrence book includes good sections on the thoracic elements of this rotation which are not included in the other books. In addition, you need the usual pocket books such as the Pocket Pharmacopeia or Epocrates which may be used to look up dosages of medications and the Maxwell Book which outlines SOAP charting, brief operative notes and discharge summary writing.

The players on any cardiothoracic service are the Cardiothoracic attending surgeon, the resident or fellow surgeon, the intern and you the medical student. You need to understand your role as both a member of the team and as a student of medicine/surgery. This means that in many cases, this busy service will require that you become very proactive in terms of getting the information that you need. You should thoroughly understand the following for every case that you encounter on this service (or any service for that matter):

• The relevant pathology of the underlying disease entity
• The relevant anatomy of the underlying disease entity
• The “gold-standard” of diagnosing the disease entity
• The accepted treatment of the disease entity
• For surgery- the surgical approach and performance of the operative procedure
• For surgery – the postoperative disposition and management of the patient

 

In the case of a patient that is undergoing a coronary artery bypass graft procedure, you need to understand the indications for the procedure, how the diagnosis of coronary artery disease was obtained (how to read the cath report), where is the disease (in which arteries), the relevant surgical anatomy, how the case is done including the operative approach, how cardiopulmonary bypass works, the effects of the cardiopulmonary bypass pump on the patient and how these effects are managed in the postoperative period, how to read and interpret data from the pulmonary artery catheter, where the grafts for bypass were obtained and how they were utilized and the care of the patient both in the intensive care unit and on the postop ward before discharge home. You should also know why the patient is discharged on certain medications and what you may expect to see and evaluate in the clinic when the patient returns for postoperative care. 

Armed with that knowledge, you should make sure that you observe (you probably won’t be actually scrubbing in these cases)the preparation for anesthesia,  how the chest is opened and closed, that you see how the grafts are harvested (done by a surgical resident) and how that wound is closed, how the grafts are sewn I place (best to use the camera overhead for this observation rather than try to look over the shoulder of the surgeons, how the pacemaker wires are placed, how the patient is placed on and taken off the cardiopulmonary bypass pump, how the chest tubes are placed in the chest cavity and how blood is evacuated from the chest cavity when the sternal wires are placed. Placement of the sternal wires is also a good opportunity for you to observe an interesting procedure.

After the case, you should accompany the patient to the intensive care unit and you should carefully note and observe the data that is obtained from the pulmonary artery catheter, the arterial line and the 12-lead ECG. You should look at the pre-operative ECG and compare the two. Another good exercise is to note where the grafts were placed and the number of minutes of pump time and any circulatory arrest time. You thoroughly familiarize yourself with the preoperative workup and the postoperative course of every patient that is on your service. Look at things like electrolyte replacement, ventilator weaning, urine output and transfer from the intensive care unit. This is also a good time to learn how to remove chest tubes and arterial lines. You should observe the conversion of the pulmonary artery catheter to a central venous line but leave the rewiring duties to a resident. If you anticipate entering a surgical subspecialty, you might observe these procedures but you should never perform these procedures as a medical student. 

In addition to the routine patients, you may get an opportunity to observe some trauma that involved the cardiothoracic service. You may see the repairs of lung lacerations, penetrating cardiac injuries and the relief of cardiac tamponade from a traumatic injury to the chest. It is always interesting to see a patient who is admitted to the emergency department with a stab wound to the chest, knife in placed, rushed off to the operating room where the object is removed and the repair completed with survival of the patient. These are some of the most interesting cases. You may also see how damaged cardiac valves are replaced and how congenital heart defects are repaired. All of these cases are under the practice of a cardiothoracic surgeon. 

The thoracic cases may afford you an opportunity to scrub in on the procedures. In the case of the video-assisted thoracic (thorascopic) lung procedures, you will have a good view of lung pathology. You can follow the patient from biopsy (in the case of a tumor) or chest wall abnormalities/problems through the repair. These cases will have interesting anatomy and will have excellent postoperative observations and challenges that will teach you many good skills. You can learn about chest tube management and the physiology of the chest cavity. You will also learn about pain management and the prevention of major postoperative complications as these patients may often be a challenge in terms of pain relief. You may get a chance to observe a thoracentesis or placement of a chest tube.

This rotation can teach you many important skills and hone your ability to understand the critical care of patients. It is an excellent learning opportunity for you. You may not get much hands-op operative experience but you can be invaluable in the post-operative care  of these patients.

Shadowing Me

Some people have asked what may be expected of a pre-med student who is shadowing a physician. I thought that I would write a bit about what I provide and expect on this shadowing experience. The expectations of the physician and the experience of the shadower definitely vary but I hope that this description provides those who have not shadowed with some things that might make the experience better.

Legal Matters

I have a confidentiality sheet that all pre-medical and medical students must sign before shadowing me. It outlines the confidentiality rules such as you may not disclose the name, condition or any other identifying information of any of the patients that you encounter during the shadowing experience. It also outlines that your may not write on any patient document while in the hospital and it outlines that you will observe all rules and regulations as you are directed by the staff of the hospital. These rules are for protection of the privacy of my patients and are pretty clearly outlined before you come to the hospital.

Dress

I ask that shadowers dress in business attire for the experience. This includes suits for males and suit or dress and jacket for females. I don’t ask for white coat because I seldom wear one. I have a badge that identifies you as a Student Observer that you will wear on your jacket along with a name tag.  My patients expect that you will be professionally dressed and they are made aware of your presence. If I am going to be doing any procedures that you will be observing, I obtain their permission before you are allowed to observe anything. The staff is quite aware that I have shadowers from time to time and are very helpful in terms of making you feel comfortable. They understand the process and are happy to help me make sure that you have a good experience.

What I expect you to do

I expect you to have some expectations of what you want to achieve in participating in this experience. You should write down a few objectives and have these ready for me to go over with you. Are you there to learn about my specialty? Are you there to learn about the practice of medicine in 2008? Are you there to discuss your chances of admission into medical school? Are you there because you need an additional letter of recommendation for medical school? In short, jot down a few objectives for your visit and have them handy.

I expect you to bring a copy of your Curriculum Vitae (resume). If you have a photo attached, so much the better but I take a digital photo of you and place it with my copy of the signed Confidentiality sheet. If I am writing a letter of recommendation, I like to look at the photo and make sure that I remember the person correctly. Sometimes people will ask for a letter several weeks after their shadowing experience and I like to make sure that I remember the person.

I also like for you to bring a copy of your Personal Statement (PS) and the medical schools that interest you. I usually read your PS before we begin the day and I often offer tips for making the document stronger. I also can provide some information about specific schools that might be helpful to you. I can also suggest particular schools that might be a good fit for you too. Again, I add your PS and schools list to the folder that contains the documents that I have mentioned above.

The Day

I usually have people shadow on a day that I am in the hospital ,clinic and teaching. While it’s a long day, it usually gives the shadower a good experience. I usually have folks come on the day when I am not on call and have a lighter procedure day. I want to you see some cases but I also want you to have plenty of time to ask questions and understand as much about my practice as possible. I also will send you a list of the cases that I have scheduled and a brief description should you want to do some research before you observe.

Over lunch, which I provide, we usually discuss your career plans and I answer any questions that you might have. Again, I usually have taken a look at your CV, PS and schools list. If you are yet to take the Medical College Admissions Test (MCAT), I usually offer some tips about preparation for this very important exam. Since you will likely sit in on one of may classes, I usually give you a copy of my lecture notes so that you can follow along. The class is a great time for you to meet some of my pre-clinical medical students or some of the third-years that are on my service. They usually have loads of hints and suggestions about application to medical school.

When the day is done, usually about 5 pm (just before evening rounds), I usually go over any questions that you might have and any expectations that you have of me that we haven’t gone over during lunch. If you need a letter of recommendation, I ask that you provide a deadline for me so that I can make sure that you letter is out in a timely fashion.

Most shadowers get a chance to participate in morning rounds, a few cases, in my clinic and sit in on a class or lecture. I think that while the day is pretty full for you, it gives you a fairly realistic idea of what this profession involves. After all, this is your shadowing experience and you have a short period of time to make the most of your experience. I also feel that you need to have exposure to the daily routine of what I do so that you can compare your shadowing experience with me to others that you might have. Again, this gives you a more realistic experience.

Finally, I do have people who come back for a second day sometimes. These folks usually have shadowed me early in their undergraduate career and now want to spend a little more time working on buffing their application before they submit it. I certainly do not ever have a problem with this. I definitely recommend that people shadow at several stages in their undergraduate career as sometimes the shadowing experience can hone your desire to pursue medicine if you were unsure the first time around.

Good sources of names of physicians who will allow you to shadow are the local medical societies in your locale. Most local medical societies will have lists of physicians who will work with you. I know that in many large metropolitan areas the city medical society will make all of the arrangements for you. This was how I was able to shadow several physicians before I entered medical school.

Another source of physicians who will allow you to shadow would be any medical schools that are nearby. You might contact the individual clinical departments of the medical schools which may be able to match you with the name of a physician or two that would allow you to shadow. Other resources are your family or personal physician who may provide this service or know a colleague or two that might allow you to shadow.

The important things to do are:

• Have a list of objectives that you want to accomplish on this visit.
• Find out what the dress code will be, what time you are expected to finish and what the daily agenda will be.
• Have a copy of your CV, personal statement and list of schools if possible (attach a small passport-sized photo) to your CV.
• If you need a Letter of Recommendation, be sure to provide a deadline, an address as to where the letter should be sent and if the letter is going to an individual or a committee.

The last thing is to enjoy your experience being mindful of the person who is allowing you to shadow them. This means being mindful of the confidentiality of their patients and send a letter of thanks when you are done.
