OSCE Surgery Block

P a g e | 1 Quick Review for OSCE | AlBrahim-Al-Enezi

Introduction

These notes are just a guide for a quick review of the most important clinical

examinations and history taking in surgery block. For more details, you can go

back to your reference book.

Before OSCE:

o Sleep well: Sleeping well is more beneficial than studying all night long. o Bring all your equipment: Stethoscope, ophthalmoscope…" o The key to OSCE success is practice. o Behave in a polite, professional way.

Before starting any examination:

o Wash your hands. o Introduce yourself. o Explain to the patient, take permission and maintain privacy. o Before examining the patient, you should comment on:

Consciousness and alertness. Is the patient in distress, pain or comfortable. Connection to: O2, ECG monitor or IV line access.

o After you finish, thank the patient and cover him\her.

General Surgery

Abdominal Examination

Position and Exposure:

Lying flat with both hands on the side & expose from nipples to mid-thigh.

Inspection: Best done from the patient’s feet side of the bed.

o Hernias: Let the patient stand, and then ask the pt. to cough and sit. o Contour and Distention (5 F: Feces, fetus, flatus, Fat, Fluid). o Symmetry: Movement with respiration (pattern of breathing). o Scars: Appendectomy, peritoneal dialysis, nephrectomy, ascites. o Prominent veins "portal HTN", caput medusa around the umbilicus. o Umbilicus "inverted or everted". o Striae, bruising, rashes, visible peristalsis, pigmentation.

Palpation: Ask if there is any pain and observe the patient's face.

o Tenderness: Superficial: Guarding, rigidity, rebound. Deep: deep masses, Murphy's sign.

o Organomegaly: a) Liver: Palpate the liver edge & percuss for span "8-12 cm" from above.

b) Spleen: You can't go above it, has a notch, and enlarges inferomedially.

Palpate "pt. flat" & "pt. lying over his right side". Percuss over left costal margin-anterior Axillary line with

full expiration.

c) Kidneys: bimanual examination "balloting".

d) Bladder: percussion.

Percussion: The whole abdomen.

o Ascites (Shifting dullness & fluid thrill "huge ascites").

Auscultation: o Bowel sounds: Exaggerated: Proximal to the obstruction.

Absent: paralytic ileus or distal to the obstruction". o Bruit: Renal "Renal artery stenosis. Liver "Hepatocellular carcinoma".

Others: o Special test for appendicitis: Obturator, Psoas, Rovsing signs. o Lymph nodes: including supraclavicular (Virchow's node). o Rectal and genitalia examination + Back & leg examination (edema).


History of a Lump Age and gender.

When did he/she notice the lump? Is it the first time?

What made the patient notices the lump?

Site.

Predisposing events.

Symptoms of the lump: pain, discharge, disfiguring, or restrain certain movements, respiratory or swallowing, change in voice.

If discharge: Quantity, quality, color, smell.

Associated Symptoms: fever, weight loss, night sweats, fatigue.

Has the lump changed? Size, shape, color, tenderness since first notice

Does the lump ever disappear? On lying down or exercise.

Previous exposure to radiation to the neck.

Any other lump.

Treatment done for this lump before.

What does the patient think caused the lump?

Examination of a Lump Wear gloves and proper exposure (If in the limb, expose both for comparison).

Inspection: o Site, size, shape, color, surface, and edge (well or ill defined), symmetry. o Discharge (color, quantity, quality-mucous, purulent, blood- , and smell). o Skin changes, scar, and area around the mass.

Palpation: o Temperature, tenderness. o Consistency (stony hard, firm, rubbery, soft), Surface (smooth or

irregular) o Mobility, fixation to skin, attached to underlying tissue, going above it. o Pulsatility, reducibility, fluctuation, translumination (fluid-filled lesion).

Percussion: Resonant or dull, fluid thrill.

Auscultation: Bruit if A-V malformation.

Surrounding tissues: o Regional lymph nodes. o Local tissues: skin, muscles, vessels, and nerve supply.


Abdominal Hernia Common physical signs to all hernias but are not always present:

o Congenital or acquired weak spots in the abdominal wall. o Most hernias can be reduced. o Most hernias have an expansile cough impulse.

The last two signs may be absent, especially if the hernia is tightly constricted at its neck.

Examination of an inguinal hernia: Always examine bilaterally.

Ask the patient to stand up o During a routine supine abdominal examination, you discover a lump that

looks like hernia, complete the examination then ask the patient to stand up in order to determine the size correctly.

Inspection: From the front. o Site and shape. o Inguinal hernia: Above the crease of the groin. o Femoral hernia: More medial and inferior.

Palpation: From the front. o Scrotum and its content. o In men, examine its upper edge. If you can get above it Scrotal

swelling NOT hernia.

Palpation: From the side. o On the same side as the hernia. Place one hand in the patients back to

support him, and your examining hand on the lump with your fingers and arms roughly parallel to the inguinal ligament.

o You must ascertain the following facts about the lump: Position, size, shape. Temperature, tenderness, and tension. Composition (solid, fluid, or gaseous). Reducibility.

Expansile cough impulse: o Compress the lump firmly with your fingers then ask the pt. to cough.

Is the swelling reducible? o Ask the patient to reduce it him/herself. o If the patient can't reduce it, press firmly to reduce the tension of the

lump. Then gently compress the lower part of the swelling. As the lump gets softer, lift it up towards the external ring. Once it has all passed in through this point, slide your fingers upwards and laterally towards the internal ring to see if the hernia.

o If there is any difficulty in reducing the hernia, ask the patients to lie down and try again.


Remove your hand and watch the hernia reappear o Indirect hernia: Slide obliquely downwards along the line of the canal. o Direct hernia: Project directly forwards.

Percuss and auscultate the lump o If there is gut in the sac, it may be resonant and there may be audible

bowel sounds.

Examine the other side: o Inguinal hernia is commonly bilateral, particularly when it is direct.

Examine the abdomen o Raised intra-abdominal pressure, such as a large bladder, an enlarged

prostate, ascites, chronic intestinal obstruction, or pregnancy.

Cardiovascular and respiratory assessment: Fitness for operation.

Rectal Examination

Position and Exposure: o Lying flat on left side while flexing the hip & knee.

Inspection: o Thrombosed external hemorrhoid. o Skin tags, rectal prolapse, anal fissure. o Ask the patient to bear down then inspect.

Palpation: o Wear gloves & lubricate your finger. o Place finger at anus until the patient relaxes then gently insert your finger

and note sphincter tone at the anal verge. o Ask the pt. to bear down; this will bring high rectal masses down. o Palpate all walls of the rectum for masses, tenderness, or polyps. o Palpate the prostate then check your finger for signs of bleeding.

Rectal Bleeding Bleeding:

o Onset, frequency, progression, color (bright red or mixed), amount. o On stool, mix or on towel paper & stool shape. o Aggravating and relieving factors. o Associated Symptoms: pain, change in bowel habits, defecation problem

Example o Patient X and date. o Lateral x-ray for Right femur showing hip, pelvis and knee there is oblique

fracture in mid shaft and dorsal displacement and 3 cm overlapping also there's angle superiorly about 45 degree the knee is rotated internally.

o I would like to see AP view.

Closed Fracture Examination Start with ABC: Rule out other injuries or open fracture.

Look: o Expose both limbs “look at each limb”. o Deformity, shortening of limb, or open fracture. o Swelling, bruising or bleeding.

Feel: o Gently for tenderness and crepitus.

Move: Joint above and below.

Neurovascular: o Pulses and capillary refill. o Nerve: Motor and sensory.
