The physical examination, in clinical medicine, is the art of acquiring a small amount of information while looking fancy. It doesn't usually make the diagnosis... but can help you along that path.

The history is far more important. The radiology is more informative and the labs and pathology often more definitive.

The bit below is far from comprehensive and doesn't even think of pretending to be that. It was written from the perspective of someone that sorta knows the stuff. It is useful perhaps only as a review.

This was written to review the physical exam and serve as a template for the examination at autopsy... where one sees a lot more 'cause the subject doesn't have to be in one piece after one is done.

Thorax

Respiratory

Inspection

Face & neck:

  • Respiratory distress:
    • Purse-lip breathing.
    • Nasal flaring.
    • Cyanosis - lips, lingual frenulum.
  • Trachea midline?
  • Accessory neck muscle use.

Peripheral:

  • Clubbing (lung causes DDx: abscess, bronchiectasis, cancer, decr. O2, empyema, fibrosis alveolitis).
    • Clubbing should be viewed with suspicion in patient with COPD, as it should not be seen in the context of pure emphysema.[1] Clubbing in COPD is relatively rare; thus, in the context of COPD and smoking it should prompt a search for an occult lung cancer.[2]
  • Cyanosis - fingernails.

Chest:

  • Respiratory distress:
    • Intercostal indrawing.
    • Diaphragmatic paradox.

Chest wall deformities:

  • Kyphosis.
  • Scoliosis.
  • Barrel chest (seen in emphysema).
  • Pectus excavatum.
  • Pectus carinatum.

In trauma:

  • Fail chest.
  • Sucking chest wound.

Palpation

  • Trachea midline (may be deviated in tension pneumothorax).
  • Tactile fremitus (boy-o-boy or 99).

In trauma:

  • Fail chest/broken ribs.
  • Subcutaneous emphysema (popcorn popping sound).

Percussion

  • Don't forget the apices.

Auscultation

  • Bronchial at trachea.
  • Vesicular at base.
  • No wheeze. No stridor (upper airway). No crackles.

Vocal fremitus

  • Egophony
  • Whisper pectoriloquy

Extras

  • Calf tenderness - think about DVT/PE.
  • Homans' sign - calf pain on dorsiflexion (suggestive of DVT).
  • Vitals - may help figure-out tumour vs. infection.

Precordial

Inspection

  • Masses, scars, lesions, signs of trauma/previous surgery.

Palpation

Point of maximal impulse (mnemonic SALID):

  • Size - should be less than 2-3 cm.
  • Amplitude - should be tapping.
  • Location - 5 ICS MCL.
  • Impulse - monophasic (biphasic abnormal).
  • Duration - <2/3 of systole.

Chest wall:

  • Trills (at valve locations).
  • Heaves with heel of hand.

Auscultation

  • S1, S2 normal.
  • No S3. No S4. No murmurs. No rub.

Head & neck

Neck nodes

Palpation

  • Use cricoid cartilage as a landmark.
  • Palpate both lobes & isthmus - get patient to swallow whilst doing this.

Percussion

  • None.

Auscultation

  • Listen for bruit - get patient to hold their breath.

Extras

  • Reflexes (hyperactive in hyper, hypoactive in hypo).
  • Vitals
    • Tachycardia in hyper.
    • Rhythm disturbance (e.g. atrial fibrillation) in hyper.

Abdomen

General abdominal exam

Note that the order is different; it is not IPPA'. Auscultation is moved-up so one doesn't have a disturbed abdomen.

One should palpate the painful area last (for practical and psychological reasons).

Inspec.

  • Masses, scars, lesions, signs of trauma & previous surgery.
  • Distension.
  • Bulging flanks.
  • Ecchymoses:
    • Grey-Turner sign (flank).
    • Cullen's sign (periumbilical).
  • +/-Stigmata of liver disease.

Auscultation

  • Listen for bowel sounds - should listen for 1 minute to r/o movement.
    • Hyperactive in mechanical obstruction.
    • Tinkling in ileus.

Percussion

  • Hyperresonance - upstream in mechanical obstruction.
  • Dull - mass?

Palpation

  • Soft/light... then deep.
  • All four quadrants + periumbilical region.

Routine special

  • Rectal examination with digital rectal exam and FOBT.
  • Testicular exam/exam for hernias - particularly important in the context of small bowel obstruction (SBO).
  • Murphy's sign (for cholecystitis) - stops inspiration when hand in RUQ (below gallbladder) - contacts the inflammed gallbladder.

Appendix

  • Obturator sign - pain with internal rotation.
  • Psoas sign - patient doesn't straighten leg (Px with extension when hip flexed).
  • Rovsing sign - Px when poking at LLQ.
  • Rebound tenderness - Px with quick letting go after deep palpation (hurts like hell... should warn the patient).

Liver

Inspection

Rule of fives.

Head - mnemonic FEATS:

  • Fetor hepaticus (awful smell from mouth).
  • Encephalopathy.
