Study Notes
Prior to Examination
- Ensure a warm, private environment and check patient ID.
- Consider the need for a chaperone.
- Perform hand hygiene, ensuring hands are warm.
- Introduce yourself and clarify your status.
- Explain the necessity of palpating the abdomen to the patient.
- Obtain verbal consent before proceeding.
- Ensure the patient has emptied her bladder to minimize discomfort.
- Position the patient supine with only the head and upper shoulders supported by a pillow.
Inspection
- Inspect the abdomen for shape, size, scars, linea nigra, striae, movements, and color.
- Palpate the abdomen to assess growth (gestational age via fundal height), fetal movements, and fetal parts.
- Determine the number, lie, position, presentation, and engagement of the fetus.
Auscultation
- Use a fetal stethoscope (Pinard or sonicaid) to auscultate fetal heart rate.
Palpation Techniques
- Maintain patient dignity by exposing only necessary areas.
- Use warm hands and gentle, even movements of the flat palmar surface.
- Avoid prodding or jerky movements to prevent uterine irritation.
Key Points to Record
- Accurate palpation requires practice and experience.
- Document:
- Fundal height
- Lie of the fetus
- Presentation
- Position
- Engagement
- Fetal heart rate
- Uncertain or abnormal findings may necessitate further investigation via ultrasound.
Measuring Fundal Height
- Palpate the fundus, usually not detectable before 12 weeks gestation.
- Apply gentle pressure and measure from the fundus to the superior border of the symphysis pubis using a tape measure.
Identifying Lie and Presentation
- Palpate down the body of the uterus to identify the lie (smooth back vs. irregular limbs).
- Differentiate between fetal parts (e.g., breech feels softer than the head).
Assessing Fetal Heart Rate
- Auscultate the fetal heart using a stethoscope placed over the baby's back, ideally near the shoulder for clarity.
- Count the fetal heart rate for one minute while simultaneously palpating the mother's pulse.
- Normal fetal heart rate ranges from 110 to 160 beats per minute.
Recording Findings
- Report observations and document:
- Fundal height in CM
- Lie of the fetus
- Presentation
- Position
- Engagement status
- Fetal heart rate
- Any other relevant findings
Lymphatic System Overview
- A closed system made of lymphatic capillaries that drain approximately 10% of intestinal fluid/lymph from tissues.
Benefits of the Lymphatic System
- Drains large protein molecules synthesized in tissues.
- Functions as the body’s defense mechanism via lymph nodes.
- Provides an alternative route for fluid drainage when there’s a blockage in the venous system.
Similarities with the Venous System
- Both originate from tissue.
- Contain unidirectional valves to prevent backflow.
- Utilize muscular pumps to assist fluid movement.
Differences between Lymphatic and Venous Systems
- Lymphatic capillaries have larger pore sizes compared to venous capillaries.
- Lymphatic capillaries drain lymph, while veins transport deoxygenated blood.
- Lymph is filtered through lymph nodes before it is drained, unlike blood in veins.
Lymph Characteristics
- Drained by lymphatic capillaries.
- Composition is similar to plasma but contains higher concentrations of white blood cells and proteins.
- Lacks red blood cells and platelets.
Lymph Nodes
- Nodular structures rich in B-lymphocytes and T-lymphocytes.
Functions of Lymph Nodes
- Absorb excess interstitial fluid.
- Destroy pathogenic microorganisms.
- Act as the “traffic police” of the human body, regulating lymph flow.
Major Lymphatic Organs
- Spleen
- Thymus
- Tonsils
Absence of Lymphatic System in Specific Organs
- Brain
- Bone
Pressure in Lymphatic Blood Vessels
- Ranges from 1-2 mm/Hg.
Major Lymphatic Ducts
- Right Lymphatic Duct: drains lymph from the right upper part of the body and opens into the right subclavian vein.
- Left Lymphatic Duct (Thoracic Duct): drains lymph from the right lower part and the entire left side of the body, opening into the left subclavian vein.
