Examen Físico Regional (Semiología)

Examen Físico Regional: Evaluación de la Cabeza y Cuello

Introducción al Examen Físico

• Se requiere un examen físico regional que incluye la evaluación de la cabeza, cuello, tórax (incluyendo mamas), abdomen y columna.

• La posición, forma, altura y proporciones del cráneo son fundamentales en el examen físico general.

Evaluación de Estructuras Faciales

• Se examinan las estructuras faciales relacionadas con el aparato respiratorio y masticador; se busca asimetría o ausencia de características normales.

• El examen físico de la cara comienza con una inspección general, incluyendo ojos, nariz, senos nasales y boca.

Inspección Detallada

• Se observa la simetría facial y se examinan las mucosas conjuntivales; se utiliza técnica específica para evaluar los párpados.

• La exploración del oído externo incluye el pabellón auricular y canal auditivo; se repite en ambos oídos para consistencia.

Exploración del Cuello

• En el examen del cuello se inspecciona su simetría y posibles deformidades; se evalúan ganglios linfáticos y movimientos cervicales.

• Se realizan maniobras específicas para palpar estructuras como laringe, tráquea y tiroides.

Maniobras Específicas en el Examen del Cuello

• La palpación debe realizarse con cuidado; nunca simultáneamente en ambos lados para evitar desmayos.

• Se utilizan varias maniobras para evaluar ganglios linfáticos cervicales superficiales y profundos.

Evaluación de la Glándula Tiroides

• La maniobra del peine permite revisar el cuello mientras se palpa el área tiroidea; es crucial observar cualquier anomalía.

• Una maniobra adicional implica que el paciente eleve los brazos para detectar disnea relacionada con bocio.

Physical Examination Techniques

Overview of Respiratory Examination Techniques

• The physical examination techniques include inspection, palpation, and percussion, primarily focusing on the lungs and airways.

• The thoracic configuration should correspond to the patient's biotype; symmetry of clavicles and scapulae is essential for assessment.

• Palpation involves checking bony structures for pain, particularly in costal joints and ribs across both hemithoraxes.

Identifying Pain Sources

• Common areas of pain include internal costal joints, which can often be confused with precordial chest pain.

• Positive palpation findings in external costal joints may indicate osteochondritis as a potential diagnosis.

Positioning for Breast Examination

• Five positions are recommended for breast examination: arms at sides, raised above head, leaning forward on a table, hands pressing against hips, and lying down.

• Ethical considerations dictate that if privacy is insufficient during examinations, a sheet should be used to cover the patient while exposing the breasts.

Conducting the Breast Examination

• A comparative assessment of both breasts is advised; use a sheet to expose them simultaneously while maintaining patient dignity.

• Inspect for symmetry in size, shape, skin color, texture, vascular patterns, moles or nodules before proceeding with further examination.

Detailed Inspection Steps

• During inspection with arms raised overhead, check for any abnormalities in breast size or shape; note any supernumerary nipples if present.

• Assess nipple characteristics including directionality and any visible discharge; inquire about previous evaluations or treatments related to breast health.

Palpation Technique

• Divide each breast into quadrants (upper outer, upper inner, lower inner, lower outer), plus an additional area known as Spencer's lobe where benign/malignant tumors may occur.

• Use circular motions starting from the upper outer quadrant moving inward; check for secretions from the nipple during this process.

Axillary Examination Importance

• The axillary region must also be examined thoroughly as it is closely linked to breast pathology; assess changes near pectoral muscles and along ribcage lines.

Examination Techniques in Physical Assessment

Overview of Examination Process

• The examination begins by assessing anxiety and explaining the procedure to the patient, ensuring they are comfortable before starting the physical examination.

• The examiner positions themselves according to their dominant hand, emphasizing the importance of proper positioning during the rational physical examination.

• Unlike standard physical examinations where inspection precedes palpation, this specific assessment alters that order for effective results.

Techniques and Procedures

• The abdomen must be adequately exposed for thorough examination while maintaining patient dignity; regions such as inguinal areas are examined carefully.

• Observations include symmetry, skin integrity, pulsations, and respiratory patterns from various angles to assess abdominal health comprehensively.

Inspection and Palpation

• During inspection, attention is given to the umbilicus's position and shape; patients may be asked to assist in revealing underlying issues like hernias.

• After visual inspection, auscultation is performed to listen for bowel sounds across different abdominal quadrants.

Auscultation Details

• Each auscultation should last a minute per quadrant to evaluate sound intensity and presence or absence of bowel sounds effectively.

• In cases of suspected paralytic ileus or other conditions, auscultation starts at opposite angles along the colon's path.

Final Steps in Examination

• Percussion follows a systematic approach similar to palpation; it helps identify fluid presence within the abdominal cavity through tactile feedback.

• Concluding remarks stress understanding differences between regional examinations (like thorax vs. abdomen), highlighting unique techniques required for each area.
