MRCS stations October 2010

MRCS Station October 2010

I will be briefly talking about the stations I had in my MRCS part B OSCEs. I will Mention them in the order I faced each station.

My first station was scrubbing. There were two examiners inside the station, and one was acting as the nurse. The description stated that you can ask the "nurse" for anything you want him/her to do. The examiners check the hands under the UV light at the end to see if you had covered all the areas during scrubbing. During the scrubbing, I was quizzed on the advantage and disadvantages of chlorhexidine and iodine, and when I would use one over the other in surgery.

Critical care: essentially the same station described by Amel. I was quizzed on TURP syndrome. As I managed to get through all the questions, the anaesetists quizzed me further on pharmacology of furosemide, and Mannitol, the mechanism of action. They also asked about the indication for intubation in a patient (all covered in Kanani's critical care vivas).

Communication skills. 10 minutes to read some notes about a patient who fell down some stairs after a drunken night out. He sustained a splenic haematoma, and the plan mentions that he needs to stay in the hospital for few days. The task is to convince the patient not to self discharge. The patient is very adamant that he wants to leave. Just had to make sure that he was not under the influence of alcohol, and has capacity to make decision. No one in my circuit managed to convince him to stay.

Pathology: scenario of a patient who presents with fever, new onset cardiac murmur, and has a previous history of rheumatic fever. The discussion was around major and minor criteria of endocarditis, most common organism, and treatment. The discussion then went onto cardiac transplants, and side effects of immunosuppression. Very straight forward station.

Critical care: scenario of a patient who was trapped under collapsed building. Discussion was around ATLS management of trauma, rhabdomyolysis, hyperkalaemia(potassium from muscle getting into the circulation).

Anatomy (specialty). Trunk and thorax. Dissection specimen of abdomen. Asked to point out stomach, duodenum, and pancreas. The different parts of stomach, blood supply. The arteries that bleed in duodenal ulcer. Parts of pancreas, blood supply, function of pancreas (exocrine and endocrine). Blood supply to the colon.

Anatomy 2. Live model present. Asked to point out tibialis anterior tendon on person. Point out Achilles tendon, Extensor Hallucis Longus, and digitorum. Dorsalis pedis and posterior tibial pulse. Show what happens when tibialis andterior and posterior contract together (inversion of the ankle). Point out where peroneus longus attaches. Nerve supply of tibialis anterior, and peroneous longus. Show me where you would test sensation of superficial and deep peroneal, and sural nerve. Demonstrate ankle and knee jerk, and the nerve roots.

Anatomy 3. Dry skeleton. Asked to point out the different parts of the humerus, and sites where nerves can be damaged. Asked what lies around the radial nerve in the radial groove (lateral and medial head of triceps). Origin and insertion of rotator cuff muscle. The examiner pointed to the ASIS and asked me what that point is called, and asked what attaches there (sartorius). Asked which nerve gets compressed around there and what is the pathology called (meralgia paraesthetica). Asked about origin and insertion of quadratus femoris.

Clinical skills: catheterisation on a plastic model (with a live patient sitting on the other side). Quizzed on what I would do if I can't get the catheter in (try bigger size, in experienced hands introducer, or SPC if still can't catheterise. Then quizzed on management of a patient who presents with abdo pain, and tachycardia.they were describing a ruptured AAA case, and how you would manage the patient.



Round 2.

Cardiovascular examination. Patient had a pacemaker. Asked about what precautions I should take; ppm check, careful use of diathermy.

Comm skills2. 10 minutes to read notes about a RTA victim with pulseless leg. Task was to call the trauma consultant to come to hospital. Quizzed about ATLS, management of open fractures, compartment syndrome.

Comm skills 3. Assess cognition of a patient awaiting elective hip replacement. Patient has AMTS of 2/10. Asked what I would do; collateral history from family, GP etc. If new, then investigate cause for confusion. Postpone surgery for now as needs investigation of confusion.

Examination 1. Knee exam of a patient with relatively new arthroscopic ports. Tender medial and lateral compartments, and patient had crutches hidden behind bed. Differential diagnosis: OA, and rheumatoid, tests I would do (weight bearing x-rays, bloods). Finally management of knee pain.

Hernia and scrotal examination: patient with bilateral inguinal hernia, and a hydrocoele. Simple question on differential diagnoses of lump in groin/scrotum, and management of hernias.

Head and neck examination. Examine a patient who has pain in submandibular region pain on eating. I performed normal neck exam, and then bimanual examination of submandibular glands, I wasn't able to feel any abnormalities, and was a but worried that i may be missing something. The examiner then said to me "I appreciate this is a normal patient...but what would you find in a patient with similar symptoms" I breathed a sigh of relief and talked about submandibular calculi. Asked about what nerves can be damaged in submandibular gland surgery, and quizzed about anatomy of parotid gland.

History. Take a history of a patient with increased urinary frequency, hesitancy, and dribbling. Basic questions on management of BPH.

Critical care 3. Scenario of a patient who had a reversal of ileostomy 3 days ago, now has abdo distension, spiking temperatures. Asked about bowel obstruction, and anastomotic leak. Differentiating true obstruction from pseudo obstruction (no bowel sounds in pseudo, and tinkling In true obstruction).

History. Patient with back pain, and numb great toe. Probable disc protrusion and compression of nerve roots. Quizzed about cauda equina, and how I would manage this patient.

Overall, very fair and straightforward exam. The examiners are generally very nice and will help you work out the answer. There are lots of staff that take you from one floor to the other, so no chance of being lost. The exam however is very long and tiring.There is a break between each 9 station where you get coffee and biscuits.
