General Principles of Physical Examination

Key Attributes of a Physician
  • Elegant Appearance: Reflects professionalism.
  • Decent Manner: Essential for patient comfort.
  • Kind Attitude: Builds trust with patients.
  • High Responsibility: Aids in comprehensive patient care.
  • Good Medical Morals: Upholds the integrity of the profession.
Hygiene Practices
  • Wash hands in front of the patient, demonstrating good hygiene.
  • Use soap and water, as it significantly reduces disease transmission.
Examination Procedure
  • Exposing the Area: Only the area for examination should be exposed.
  • Chaperone Provision: Offer a chaperone for both genders.
  • Explaining Steps: Clearly explain the examination steps beforehand.
  • Sequential Approach: Perform the examination in an organized manner.
Communication During Examination
  • The examiner should engage with the patient, discussing their health and answering any questions.
  • This interaction can alleviate patient anxiety and build a good physician-patient relationship.

Use of Gloves

Situations Requiring Gloves
  • When examining individuals with exudative lesions or weeping dermatitis.
  • While handling blood-soiled materials or clothing.

Abdominal Examination Principles

Setting
  • Lighting: Ensure the examination area is well-lit.
  • Patient Comfort: The patient should be relaxed.
  • Positioning: Position the patient flat and supine, with arms at the sides or across the chest.
Pre-Examination Steps
  • Instruct the patient to empty their bladder before the examination.
  • Ask the patient to identify any painful areas to examine those last.
  • Observe facial expressions for discomfort throughout the exam.
Techniques for Examination
  • Use warm hands and a warm stethoscope.
  • Maintain short fingernails.
  • Approach the patient calmly and slowly, explaining each step.
  • Stand on the right side of the patient to conduct the examination primarily with the right hand.
  • Ask the patient to keep their mouth slightly open and to breathe gently.
  • If abdominal muscles are tense, ask the patient to rest their feet on the table with hips and knees flexed.
  • Drape a sheet over the lower body for patient comfort.

Gastrointestinal Examination

Components of Examination
  1. General Examination
  2. General Inspection
       - Look for nutritional status (wasting), pallor, jaundice, pigmentation, and mental status (encephalopathy).
  3. Inspection of Specific Areas
       - Hands and Arms: Assess for palmar erythema, Dupuytren's contractures, spider naevi, bruising, wasting, scratch marks.
       - Face, Eyes, Mouth: Check for breath odor (fetor hepaticus), lips, angular stomatitis, cheilitis, ulceration, gum health (gingivitis, bleeding), presence of Candida, pigmentation, and tongue conditions (atrophic glossitis, leukoplakia).
Anatomical Considerations
  • Abdominal Landmarks:
       - Front: Midabdominal line, upper abdominal angle, xiphoid process, costal margin, umbilicus, etc.
       - Lateral: Midaxillary line, posterior axillary line, anterior axillary line.
       - Remember the anatomical locations while assessing for abnormalities.
Abdominal Quadrants
  • Divide the abdomen into four quadrants:
       - Right Upper Quadrant (RUQ): Liver, gallbladder, stomach, duodenum, right kidney, right colic flexure.
       - Right Lower Quadrant (RLQ): Cecum, appendix, right ovary and uterine tube (female), right ureter, right spermatic cord (male).
       - Left Upper Quadrant (LUQ): Left lobe of liver, spleen, stomach, jejunum, proximal ileum, pancreas, left kidney.
       - Left Lower Quadrant (LLQ): Sigmoid colon, left ovary, left uterine tube.

Special Signs and Techniques

Inspection
  • Check the contour and shape of the abdomen noting whether it's flat, distended, or scaphoid.
  • Assess for generalized distention (ascites, tympanites) and local distention or masses.
  • Inquire about attributes such as symmetry, bulging, and movement.
Auscultation for Bowel Sounds
  1. Conduct auscultation before percussion or palpation.
  2. Identify normal bowel sounds (4-5 times/min), hyperactive sounds (>10 times/min), and hypoactive sounds (<4 times/min).
  3. Bowel sounds can reflect gastrointestinal activity and indicate conditions such as obstruction or peritonitis.
Percussion Techniques
  • Percussion reveals gaseous distension, fluid presence, or solid masses.
  • Common percussion sounds include tympany (from gases) and dullness (from organs like the liver).
  • Assess the liver size through percussion techniques, with normal liver placement typically below the costal margin.
Palpation Techniques

Types of Palpation:

  • Light palpation: Assess muscle tone and cutaneous sensitivity.
  • Deep palpation: Identify abdominal masses or tenderness through deeper pressure techniques.
Special Signs in Abdominal Examination
  • Murphy's Sign: For cholecystitis, observed when the patient experiences pain upon deep inspiration during palpation of the gallbladder.
  • McBurney's Point: Tenderness indicative of appendicitis located in the right lower quadrant.
  • Rebound Tenderness: A sign of peritoneal irritation.

History Taking Techniques

  1. Inquire about family history (e.g., colon cancer, gallstones).
  2. Assess factors affecting the patient's health such as diet, lifestyle, and previous diseases.
  3. Document abdominal symptoms including pain localization, type, severity, timelines, and aggravating or relieving factors.
  4. Take note of other gastrointestinal symptoms, such as nausea, vomiting, changes in bowel movement patterns, jaundice, and associated symptoms like weight loss.

Summary of Abdominal Anatomy

  • Be familiar with anatomical landmarks and organ locations.
  • Understand key signs that indicate various gastrointestinal and systemic issues.

Conclusion

These notes compile essential information regarding abdominal examination methods, techniques, and anatomical considerations necessary for effective clinical practice. Continuous engagement and hands-on practice are pivotal for mastering the abdominal examination.
