Lung, Thorax & Spine Exams Charlie Goldberg, M.D. Professor of Medicine, UCSD SOM Charles.goldberg@va.gov Exposure Is Key – You Cant Examine What You Can’t See! Anatomy Of The Spine Cervical: 7 Vertebrae Thoracic: 12 Vertebrae Lumbar: 5 Vertebrae Sacrum: 5 Fused Vertebrae Note gentle curve ea segment Anatomic Images courtesy Orthospine.com Spine Anatomry – Courtesy Ortho Spine Spine Exam • W/patient standing, observe: shape of spine. – Stand behind patient, have them bend@ waist – if Scoliosis (curvature) one shoulder appears “higher” • Range of motion – Direct patient to: – Bend backwards – Bend side to side, rotate @ waist • Palpate lightly w/fist over entire spine – if underlying inflammation (e.g. fracture, infection, tumor)Æpain – rare to elicit on screening exam Pathologic Changes In Shape Of Spine Thoracic Kyphosis (bent forward) Scoliosis (curved to one side) Lung Exam • Includes Vital Signs and Cardiac Exam • 4 Elements: Observation, Palpation, Percussion, Auscultation (also for Cardiac & Abdominal) Observation • ? Ambulates w/out breathing difficulty? • Appearance Æ? sitting up, leaning forward, inability to speak, pursed lipsÆsignificant compromise • ? Use of accessory muscles of neck (sternocleidomastoids, scalenes)Æ significant compromise. Scalene and Sternocleidomastoid Anatomy (http://www.amtamassage.org) Observation (cont) • Audible noises? • Shape of spine and chestÆ can affect lung volumes and function • Color & shape nails (clubbing, cyanosisÆ rare) Pathologic Changes In Shape Of Chest Barrel Chested (hyperinflation secondary to emphysema) Clubbing and Cyanosis clubbing cyanosis Lung Anatomy (please wait for video to load) Thoughts On Gown Management & Appropriately/Respectfully Touching Your Patients • Several Sources of Tension: – Area examined must be reasonably exposed – yet patient kept as covered as possible – Palpate sensitive areas to perform accurate exam - requires touching people w/whom you’ve little acquaintance – awkward, particularly if opposite gender – Exam not natural/normal part of interpersonal interactions - as newcomers to medicine, you’re particularly aware & hence very sensitive Æ a good thing! Keys To Performing a Respectful & Effective Exam • Explain what you’re doing (& why) before doing itÆ acknowledge “elephant in the room”! • Expose minimum amount of skin necessary - “artful” use of gown & drapes (males & females) • Examining heart & lungs of female patients: – Ask pt to remove bra prior (can’t hear well thru fabric) – Expose L side of chest to extent needed – Enlist patient’s assistanceÆ positioning breasts to enable cardiac exam • Don’t rush, act in a callous fashion, or cause pain • PLEASE… don’t examine body parts thru gown: – Poor technique – You’ll miss things – You’ll lose points on scored exams (OSCE, CPX, USMLE)! NO! NO! NO! Good Exam Options Palpation • Patient in gownÆchest accessible & exposed • Explore painful &/or abnormally appearing areas • Chest expansion – position hands as below, have patient inhale deeplyÆ hands lift out laterally Palpation – Assessing Fremitus • Fremitus =s normal vibratory sensation detected by palpating hand when patient speaks • Place ulnar aspect (pinky side) of hand firmly against chest wall • Ask patient to say “ninety- nine” • You’ll feel transmitted vibratory sensationÆ fremitus! • Assess posteriorly & anteriorly (i.e. lower & upper lobes) Lung Pathology - Simplified • Lung =s sponge, pleural cavity =s plastic container • Infiltrate (e.g. pneumonia) =s fluid within lung tissue itself • Effusion =s fluid in pleural space but outside of lung Fremitus - Pathophysiology • Fremitus: – increased w/consolidation (e.g. pneumonia) – Decreased in absence of air filled lung tissue (e.g. effusion). Normal Increased Normal Decreased Percussion • Normal lung filled w/air • Tapping over it generates drum-like soundÆresonance • When no longer over lung, percussionÆdull (decreased resonance) • Work in “alley” between vertebral column & scapula. Percussion - Technique • Have patient cross arms in front, grasping opposite shoulder (pulls scapula out of way) • Place middle finger of one hand flat against back, other fingers off • Strike distal interphalangeal joint with middle finger of other hand - strike 2-3 times @ ea spot Percussion (cont) • Use loose, floppy wrist action – percussing finger =s hammer • Start @ top of one sideÆthen move across to same level, other sideÆalternate R & L as move downÆrepeat ‘til reach bottom (3-4 spots/side) • @ Bottom of lungs, detect diaphragmatic excursionÆ difference between diaphragmatic level @ full inspiration v expiration (~5- 6cm) • Percuss upper lobes (anterior) • Cut nails to limit bloodletting! Ohio State University School of Medicine Interactive Learning Center – Simulated Percussion 1 2 34 5 6 78 • Difficult to master technique & to detect subtle tone changes - expect to be frustrated! • Practice – on friends, yourself (find your stomach, tap on your cheeks, etc) • Detect fluid level in container • Find studs in wall Expect To Be Frustrated! Percussion: Normal, Dull/Decreased or Hyper/Increased Resonance • Causes of Dullness: – Fluid outside of lung (effusion) – Fluid or soft tissue filling parenchyma (e.g. pneumonia, tumor) • Causes of hyper- resonance: – COPDÆ air trapping – Pneumothorax (air filling pleural space) Hyper-Resonant all fieldsÆCOPD Hyper-Resonant R lungÆPneumothora Dull Normal Ausculatation • Normal breathing creates soundÆ appreciated via stethescope Æ “vessicular breath sounds” • Expiration normally softer then inspiration • Time of expiration ~2x > inspiration • Pay attention to: quality of sound, inspiration v expiration, location & intensity Lobes Of Lung Where you listen dictates what you’ll hear! LUL RUL LLL RLL RUL LUL RMLRLL LLL Posterior View Anterior View Lobes Of The Lung (cont) RLL RML RUL LLL LUL Lateral Views Trachea Trachea Auscultation (listening w/Stethescope) - Technique • Put on stethescope - ear pieces directed away from you, diaphragm engaged • Have patient cross arms, grasping opposite shoulders Areas To Auscult • Posteriorly (lower lobes) ~ 6-8 places - Alternate btwn R v L as move down (comparison) - ask patient to take deep breaths thru mouth • Right middle lobe – listen in ~ 2 spots – lateral/anterior • Anteriorly - Upper lobes – listen ~ 3 spots ea side • Over trachea 1 2 34 5 6 78 Pathologic Lung Sounds • Crackles/Rales – “Scratchy” sounds associated w/fluid in alveoli (e.g. pulmonary edema, pneumonia) • Ronchi – “Gurgling” type noise, caused by fluid in large & medium sized airways (e.g. bronchitis, pneumonia) • Wheezing-Whistling type noise, loudest on expiration, caused by air forced thru narrowed airways (e.g. asthma) • Stridor - Inspiratory whistling type sound due to tracheal narrowingÆ heard best over trachea Pathologic Lung Sounds (cont) • Bronchial Breath Sounds – Heard normally when listening over the trachea. If consolidation (e.g. severe pneumonia) upper airway sounds transmitted to periphery & apparent upon auscultation over affected area. • Absence of Sound- In chronic severe emphysema, often small tidal volumes & thus little air movement. – Also w/very severe asthma attack, effusions, pneumothorax Lung SoundsOhio State University School of Medicine Interactive Learning Center – Lung Sounds R.A.L.E Lung Sound Repository UCLA Heart & Lung Sound Simmulator Other Auscultation “Tools” • Egophany – in setting of suspected consolidation, ask patient to say “eee” while auscultating. Normally, sounds like “eee”.. Listening over consolidated area generates a nasally “aaay” sound. Putting It All Together: Few findings pathognomonic Æ put ‘em together to paint best picture. • Effusion – AuscultationÆ decreased/absent breath sounds – PercussionÆ dull – FremitusÆ decreased – EgophanyÆabsent • Consolidation – AuscultationÆ broncial breath sounds – PercussionÆdull – FremitusÆincreased – EgophanyÆ present Vs Summary of Skills □Wash hands Spine □ Inspect (shape, curves); Examine (range of motion, palpation) Lungs and Thorax Observation & Inspection □ Patient breathing □ Chest shape □ Fingers/nails Palpation □ Chest excursion □ Fremitus Percussion □ Alternating R & L lung fields posteriorly topÆbottom; & anteriorly □ Determines diaphragmatic excursion Auscultation □ R & L lung fields posteriorly, top Æbottom, comparing side to side □ R middle lobe □ Anterior fields bilaterally Time Target: < 10 minutes Lung, Thorax & Spine Exams Exposure Is Key – You Cant Examine What You Can’t See!
