Document Summary
Normally in midline palpate for any tracheal shift. Space should be symmetrical on both sides when you put finger on the trachea in the sternal notch and slip to each side. Note any deviation from midline uninfected side with an aorta aneurysm, a tumor, unilateral thyroid lobe enlargement, and pneumothorax/ Trachea pulled to affected side with (diseased) larger atelectasis, pleural adhesion, fibrosis. Tracheal tug = rhythmic downward pull that is synchronous with the systole and that occurs within aortic arch aneurysm. Look for diffused enlargement or a nodular lump. Abnormalities: enlarged lobes easily palpitated before swallow or are tender to palpation or presence of nodules or lumps. Bruit occurs with accelerated or turbulent blood flow = indicates hyperplasia of the thyroid (hyperthyroidism) Note an abnormal increase in head size or failure to grow. Microcephalic- head size below norms for age. Frontal bulges or bossing occur with prematurity or rickets. Infant with cephalhematoma is at greater risk for jaundice.
