My free afternoons have been taken from me! But unlike Biostats and anatomy lab, I actually enjoy the two hours spent in ICM 2(Intro to Clinical Medicine) each day. We started class last week, but from this point on, all AUC students have to take ICM 3, 4, 5, and 6 for the duration of Basic Sciences on the island. The purpose of the course is to prepare students for the clinical years of medical school where we will be expected to know how to properly record a medical and family history and perform a full physical exam on a patient.
ICM 2 includes both lecture and small groups. The lectures were a bit boring since they mainly covered professionalism, communication skills, and cultural competency, but luckily we finished all the lectures last Thursday. From Monday to Thursday for the next two weeks, my classmates and I will be meeting in our "small groups". Each group is headed by one doctor and is comprised of 12 or so students. We spend the first hour of class practicing our interview skills on some "patients." These patients are pretty much always spouses from the Spouse Organization on campus. They get paid to learn a few characters and act them out for each student. It's somewhat awkward trying to interact with a "patient" when everyone in the room is just watching you and analyzing everything you do wrong. It's all just a little too contrived for me and I just feel like I'm a terrible, terrible actor struggling to remember my lines and cues. Nothing is coming naturally during my interviews. Not my introductions, not when I ask questions, not even when I smile. In real life, I like to think I'm not socially inept and that I actually interact pretty well with patients in an office/hospital setting, but this is ICM world. I need to get over my stage fright sometime.
The second hour of ICM is spent learning how to conduct the various exams for the eyes, head, neck, etc and how to use some of our medical instruments like the stethoscope, ophthalmoscope, and sphygmomanometer (blood pressure cuff/pump). We did some blood pressure work yesterday and learned how to do an eye exam today, but I'm going to quickly go back to last week where we learned where and how to listen for the heart. We went to
Harvey lab and all students were given a wireless stethoscope linked to the lecturer's stethoscope. Wherever he put his diaphragm/bell on the fake, large, rubbery body that is Harvey, we could also here the heart beat our ear pieces. The following diagram quickly summarizes the main points for heart auscultation. Click on the diagram to enlarge.
note: "ICS" stands for intercostal space
Systole/Diastole= Lub/Dub= Ventricular Contraction/Ventricular Relaxation
Physiological Heart Sounds:
S1= Closure of AV valves (Tricuspid and Mitral)
S2= Closure of Semilunar valves (Aortic and Pulmonary)
S3= Filling of Ventricle (normal in young people and the physically fit)
Pathological Heart Sounds:
S3= Filling of Ventricle (abnormal in people over 40 years of age)
S4= "Atrial Kick" during diastole (if heard, always pathological)
I'm already tired of writing. I'll probably do a couple more posts on ICM at a later date.
