The role of palpation in physical examination
Physical examination always begins with a general inspection, which is the very first and mandatory stage of diagnostics. This stage is invariably combined with regional inspection, during which the condition of the patient's skin is primarily evaluated in detail.
There is a strict algorithm for the sequence of actions by the physician at the patient's bedside. Following the inspection (or directly simultaneously with it), three classical methods are performed sequentially without fail:
- Palpation (probing).
- Percussion (tapping).
- Auscultation (listening).
The technique of palpatio is not completely universal. It varies significantly depending on which specific organ system is being examined at the moment.
Cognitive aspect and clinical reasoning
Palpation cannot be viewed solely as a mechanical skill. It is a profound cognitive process.
- Data synthesis: Any palpation must strictly rely on the information already obtained by the physician during the preliminary history-taking and visual inspection stages. Furthermore, flawless knowledge of topographical anatomy is critically important.
- A.L. Myasnikov's principle: The outstanding clinician formulated the rule of the inseparable connection between tactile sensation and clinical reasoning. It goes: "think while palpating, and palpate while thinking."
Ergonomics and procedure preparation
To make the examination effective, it is necessary to observe a number of strict rules for preparing both the patient and the clinician.
Patient position Must be as comfortable as possible and fully correspond to the specific goals of the ongoing examination.
Physician's position
- It is necessary to adopt a comfortable posture (usually the examination is performed while seated).
- The physician must always be positioned to the right of the patient's bed.
- The physician's body orientation must be strictly facing the patient to be able to observe their reaction.
Requirements for the physician's hands
- Temperature: The clinician's hands must be warm. This is a critically important condition for preventing reflex tension in the patient's muscles caused by the touch of cold skin.
- Hygiene: The fingernails on the physician's hands must be cut short so as not to injure the examinee.
Technical nuances of execution
During the direct execution of the maneuver, it is important to maintain proper hand positioning:
- Surface contact: The entire palmar surface of the physician's hand must participate in contact with the patient's body, providing a wide area of touch.
- Active movement: The palpatory movements themselves are carried out exclusively by the fingers.
- Abdominal specificity: When examining abdominal organs, there is a mandatory condition — the physician must use the patient's respiratory movements. This is necessary to ensure the deepest possible penetration of the fingers into the abdominal cavity on exhalation.
Briefly: answers to topical questions
What types of palpation exist depending on the depth of finger immersion?
According to the cited sources, two types of palpation are named based on the depth of finger immersion:
- Superficial exploratory palpation — the fingertips do not penetrate into the thickness of the gland; the goal is to identify small subcutaneous formations.
- Deep palpation — the fingertips sequentially and gradually sink into the tissue until reaching the ribs.
For organs and formations located deep within the abdominal cavity, methodical deep gliding palpation is used.
What specific physical properties of organs and tissues can be determined using palpation?
According to the cited sources, the following parameters are evaluated using palpation:
- Quantity — single or multiple lymph nodes.
- Shape.
- Size / dimensions — including enlargement of an organ or lymph node.
- Consistency — soft, firm, elastic.
- Tenderness upon palpation.
- Mobility / displaceability — e.g., kidney mobility, respiratory mobility of the spleen, mobility of the thyroid gland during swallowing.
- Adhesiveness — to surrounding tissues or to each other into conglomerates.
- Surface characteristics — during palpation of the spleen.
- Presence of a characteristic notch on the anterior border — during palpation of an enlarged spleen.
- Type of thyroid enlargement — diffuse or nodular.
- Presence of pulsation of the thyroid gland.
Who is the founder of the method of deep gliding methodical topographical palpation?
The founder of the deep gliding palpation technique is the domestic clinician V.P. Obraztsov. In the sources, the method is named "methodical deep gliding palpation". V.P. Obraztsov developed and described a technique that allows differentiating intestinal segments through the abdominal wall. Key date: 1887 — the first detailed description of the results of targeted palpation. The method combines static sensations from contact with the skin and organ wall and dynamic sensations from penetrating deeper, pressing on the organ, and sliding off it.
Remember A.L. Myasnikov's principle: "Think while palpating, and palpate while thinking." Touch without knowledge of topographical anatomy and history data is meaningless.
Class and exam questions
In what sequence are physical examination methods applied?
Following general and regional inspection (or simultaneously with it), palpation is always performed sequentially, followed by percussion, and finally, auscultation.
Where should the physician be positioned when examining the patient?
The physician must be in a comfortable posture (usually seated), positioned to the right of the patient's bed and obligatorily facing them.
Why are warm hands necessary during palpation?
Warm hands are necessary to prevent reflex muscle tension in the patient, which may occur from the touch of cold fingers and hinder the examination.
What are the specific features of abdominal organ palpation?
The main specificity lies in the mandatory use of the patient's respiratory movements, which allows the physician's fingers to penetrate deeply into the abdominal cavity.
