Abdominal Examination Abdominal Examination Dr AbdulQader Said Murshed Consultant General, G.I., & Laparoscoic Surgeon FRCS Glasg, FRCSI, Jordanian Board Wednesday, 27/6/2018 Preparation • The environment: warmth, privacy, good light. • The examination couch or bed: opens the gap between th e pubis and the xiphisternum, relaxes the anterior abdominal wall muscles. • Exposure: ideally, patients should be uncovered from nipples to knees. A compromise is to cover the lower abdomen with a sheet or blanket while the abdomen is being palpated. • Getting the patient to relax: patient’s arms by their sides, Only press your hands into the abdomen during expiration as the abdominal muscles relax. If the above do not work, ask the patient to flex their hips to 45° and their knees to 90° and place an extra pillow behind their head. The position of the examiner • The examiner’s hands should be clean and warm with short nails. • The whole hand should rest on the abdomen • by keeping the hand and forearm horizontal, in the same plane as the front of the abdomen. Do not dorsiflexing your wrist. The examination • This should follow the standard routine of inspection, palpation, percussion and auscultation. • you must never forget to examine: – Supraclavicular lymph glands – The hands, nails and facies. – Hernia orifices. – Femoral pulses. – Genitalia. – Anal canal and rectum. Inspection • Look for any general abnormality such as cachexia, pallor or jaundice. • Inspection of the abdomen from the end of the bed, reveals any asymmetry or distension. • position, shape and size of any bulge, any changes in its shape, and whether it moves with respiration or increases with coughing. • Observe the reaction of the patient to coughing or moving. • The presence of any scars, sinuses or fistulas. dilated surface veins. Palpation • Palpate gently but deliberately, firmly and with purpose. • Keeping your hands still and feeling the intraabdominal structures moving beneath them. Palpation (cont.) • General light palpation for tenderness, guarding, rigidity, and rebound (or release) tenderness. • General deeper palpation for tenderness, when mild. • Palpation for masses. • Palpation of the normal solid viscera: The liver, The spleen, The kidneys. Palpation (cont.) liver • right hand transversely and flat on the right side of the abdomen at the level of the umbilicus. • the radial side of your index finger • deep breath. • The liver edge may be straight or irregular, thin and sharp, or thick and rounded. The surface may be smooth or knobbly. • if in doubt, begin your palpation in the left iliac fossa. Palpation (cont.) spleen • An enlarged spleen appears below the tip of the tenth rib along a line heading towards the umbilicus. • if really large, may extend into the right iliac fossa. • A normal spleen is not palpable. Palpation (cont.) spleen (cont.) • the fingertips of your right hand on the right iliac fossa just below the umbilicus. • Ask the patient to take a deep breath. • move your hand in stages towards the tip of the left tenth rib. • When the costal margin is reached, place your left hand around the lower left rib cage, and lift the lower ribs and the spleen forwards as the patient inspires. • The spleen is recognized by its shape and site and, when present, the notch on its superomedial edge. It is dull to percussion as it lies immediately beneath the abdominal wall with no bowel in front of it, unlike a renal mass. Palpation (cont.) The kidneys • Normal kidneys are usually impalpable, except in very thin people. • place your left hand behind the patient’s right loin between the 12th rib and the iliac crest. • Then place your right hand on the right side of the abdomen just below the level of the anterior superior iliac spine. • As the patient breathes in and out, palpate the loin between both hands. • An enlarged kidney can be pushed back and forth between the anterior and posterior hands. This is called balloting. Palpation (cont.) • When a kidney is very easy to feel, it is either enlarged or abnormally low • Balloting is also used to palpate a fetus in a pregnant uterus. • Bimanual palpation • balloting Percussion • The whole abdomen must be percussed, particularly over any masses. • Any area of dullness should be outlined by percussion with the abdomen in two positions to see if it moves or changes shape. An enlarged liver is dull to percussion, and its upper margin should be percussed out to assess its full dimension. • A dull area may draw your attention to a mass that was missed on palpation and indicate a more detailed and careful palpation of the area of dullness. • Percussion causes pain if peritonitis is present and is a useful method for mapping out a tender area. Percussion (cont.) • Fluid thrill. • shifting dullness, Free fluid (ascites) changes shape and moves (shifting dullness). • succussion splash. When a part or the whole of the abdomen appears distended, the patient should be held at the hips and the abdomen shaken from side to side Splashing sounds – a succussion splash – indicate that there is an intra-abdominal viscus, usuallythe stomach, distended with a mixture of fluid and gas. Auscultation • Listen to the bowel sounds. • Normal bowel sounds (Peristalsis), are low-pitched gurgles that occur every few seconds. • paralytic ileus, If you can hear the heart and breath sounds but no bowel sounds over a 30-second period, the patient probably has a paralytic ileus. • Increased peristalsis. often described as ‘tinkling’. • any systolic vascular bruits. which indicate arterial stenosis or increased blood flow through, for example, a fistula. Auscultation (cotin) • Increased peristalsis increases the volume and frequency of the bowel sounds. Also, with a change in the character of the sounds. They become amphoric in nature with runs of high- frequency gurgles, sounding like sea water entering a large cave through a narrow entrance, often described as ‘tinkling’. DIGITAL ANO-RECTAL EXAMINATION • This is commonly called a rectal examination but is actually an examination of the anus and lower rectum. • The patient should give clear verbal consent. • You need a plastic glove, some inert lubricating jelly and a good light. Tissues must be available for cleansing afterwards. • The patient should lie in the left lateral position with the neck and shoulders rounded so that the chin rests on the chest, with the hips flexed to 90° or more, and the knees flexed to slightly less than 90°. Rectal exam (cont.) Inspection • Lift the uppermost buttock with your left hand so that you can see clearly the anus, perianal skin and perineum. • Look for: • skin rashes and excoriation. • faecal soiling, blood or mucus. • scarring, or the opening of a fistula. • lumps and bumps • (e.g. polyps, papillomas, condylomas, perianal haematoma, prolapsed piles, rectal prolapse or even a visible carcinoma). • fissure, ulcers. Rectal exam (cont.) Palpation • Place the pulp of your gloved right index finger on the centre of the anus, with the finger parallel to the skin of the perineum and in the midline. • Never thrust the tip of your finger straight in. Rectal exam Palpation (cont.) • The anal canal. The tone of the sphincter, any pain or tenderness and any thickening or masses. • The rectum. Feel all around the rectum as high as possible. • The mucosa of the anus and rectum. • masses or ulcers. • Note the contents of the rectum • The recto-vesico/recto-uterine pouch. • Bimanual examination. Examination of the contents of the pelvis. • The cervix and uterus. per rectum, and on bimanual. • The prostate and seminal vesicles. .

  • Abdominal Palpation/Auscultation of Fetal Heart Rate
    Shared Maternity Care Program Guidelines Abdominal Palpation/Auscultation of Fetal Heart Rate Introduction Abdominal palpation and auscultation of the fetal heart rate is recommended as part of routine examination in pregnancy to assist in assessing fetal wellbeing. Requirements Sonicaid to identify the fetal heart rate. Aqueous gel Tape measure Recommendations for Abdominal Palpation Palpation is not performed during a contraction Only perform a GENTLE abdominal palpation for any woman with: History of ante partum hemorrhage Premature labour Severe (acute) abdominal pain Documentation of fundal height is advised from 24/40 A clinical estimate followed by a symphyso-fundal height using a tape measure should also be used A consistent approach to measurement increases accuracy Palpate the fundus first to identify the upper limit . Measure from the top of the fundus to the top of the pubic symphysis . The tape measure should stay in contact with the skin. It is not recommended to repeat the measurement. If the fundal height is more than 2cm below or above expected height, an obstetric opinion advised. Refer Antenatal Clinic 9784 2626 or if unavailable contact the obstetric registrar via switchboard 9784 7777 Fundal height measurement is of little value in a twin pregnancy. Recommendations for Intermittent Auscultation of fetal Heart Rate Is recommended from 20 weeks gestation It is important to identify maternal pulse before locating the fetal heart. Using intermittent auscultation the normal heart rate range is >110bpm and < 160bpm If fetal heart rate or fetal movements are not present after 24 weeks gestation immediately, contact the Women’s Health Unit on 9784 7959 SMCP GPLU 2018 Shared Maternity Care Program Guidelines Abdominal Palpation/Auscultation of Fetal Heart Rate Leopold’s manoeuvres:[1] a) Fundal palpation- to locate the upper pole of the fetus and note if cephalic or breech b) Lateral palpation- to locate the fetal back, anterior shoulder and limbs c) Pawlick’s grip- to assess the presentation and station.

  • Sequence of Examination Step I Note the General Appearance As You Take the History and When Initiating the Physical Examination, Usually with the Patient Sitting
    Introduction As well as history taking, Physical Examination is an important part of patient management. The goal of the P/E is to obtain valid information concerning the health of the patient. The examiner must be able to identify , analyze and synthesize the accumulated information into a comprehensive assessment. The four principles of physical examination are the following: 1. Inspection can provide an enormous amount of information. You must train themselves to look at the body using a systematic approach. 2. Palpation is the use of the tactile sense to determine the characteristics of an organ system. 3. Percussion relates to the tactile sensation and sound produced when a sharp blow is struck to an area being examined. This provides valuable information about the structure of the underlying organ or tissue. 4. Auscultation involves listening to sounds produced by internal organs. This technique furnishes information about an organ’s pathophysiology. To achieve competence in these procedures, the student must, "teach the eye to see, the finger to feel and the ear to hear" . Note: These four principles have different value in different systems. For example, Inspection is more useful in general appearance, Palpation in abdominal examination, Percussion in organ size evaluation, and Auscultation in heart examination. In abdominal examination, Auscultation is first, since performing percussion or palpation, may alter the frequency of bowel sounds. Preparing for the physical examination - Reflect on your approach to the patient - Decide on the scope of the examination - Adjust the lighting and the environment - Make the patient comfortable - Choose the examination sequence - Wash your hands in the presence of the patient - Describe your plans for the patient - Draped the patient.

Dubowitz examination From L.M. Dubowitz et al, Clinical assessment of gestational age in the newborn infant. Journal of Pediatrics 77-1, 1970, with permission Skin Color When examining a newborn baby, start by closely observing the baby. Observe the color. Is the baby pink or cyanotic? The best place to observe is the lips or tongue. If those are nice and pink then baby does not have cyanosis. The most unreliable places to observe for cyanosis are the fingers and toes because babies frequently have poor blood circulation to the extremities and this results in acrocyanosis.(See video below of baby with cyanotic feet) Also observe the baby for any obvious congenital malformations or any obvious congenital anomalies. Be sure to count the number of fingers and toes. Cyanotic Feet The most unreliable places to observe for cyanosis are the fingers and toes because babies frequently have poor blood circulation to the extremities and this results in a condition called acrocyanosis.

  • Guidelines and Discussion of the History and Physical Examination
    GUIDELINES AND DISCUSSION OF THE HISTORY AND PHYSICAL EXAMINATION U.S. Department of Health and Human Services Centers for Disease Control and Prevention National Center for Emerging and Zoonotic Infectious Diseases Division of Global Migration and Quarantine April 16, 2012 Over 600,000 refugees have resettled in the United States over the past decade, with a steady increase in numbers since 2006 [1]. Refugees arrive from around the globe and settle throughout the United States. Depending on their country of origin, refugees are at increased risk for many diseases, both infectious and noninfectious, not commonly seen in the native US-born population. Conditions such as tuberculosis and sexually transmitted infections are particularly important to recognize early, given their potential public health consequences. The initial history and physical (H&P) examination is a critically important first step in the assessment of newly arrived refugees. A thoughtful H&P can both assist in identifying disease and help refugees develop a sense of trust in our medical system and in the care being provided (e.g., in many cultures a clinical encounter is viewed as useless if a physical examination is not performed during the visit). Given the complexity of the domestic medical screening visit, it is vital that clinicians set aside an adequate amount of time, create a trusting environment, and provide competent interpretation services to facilitate compassionate and culturally appropriate history acquisition and performance of the physical examination. Performing a History The first step in the examination of a newly arrived refugee is to obtain a detailed history, including any current symptoms, past medical problems, medications, allergies, social/family history, and a mental health assessment.
