How to Improve Skin Turgor

Skin turgor cannot be directly "improved" as it is a clinical sign of hydration status, not a condition to treat—the underlying dehydration must be corrected through rehydration therapy. 1

Understanding Skin Turgor as a Diagnostic Sign

• Skin turgor should NOT be used to assess hydration status in older adults as it is unreliable in this population due to age-related loss of skin elasticity 1
• The skin turgor test (pinching and tenting skin over the shoulder blades) is only valid in younger populations for assessing moderate to severe dehydration 2, 3
• In severe dehydration, the tented skin remains elevated or is slow to resolve, accompanied by sunken eyes, lethargy, and poor drinking ability 2, 3

Correcting Dehydration: The Actual Treatment

First-Line: Oral Rehydration Therapy

• Administer oral rehydration solution containing Na 90 mM, K 20 mM, Cl 80 mM, HCO3 30 mM, and glucose 111 mM for patients able to take oral fluids 4
• Oral rehydration is safer, less painful, less costly, and superior to IV fluids when the patient can tolerate oral intake 4
• The patient's natural thirst mechanism protects against overhydration as rehydration progresses 4

Second-Line: Subcutaneous Rehydration (Hypodermoclysis)

• For patients unable to take oral fluids but not requiring emergency IV access, subcutaneous infusion is highly effective with similar efficacy to IV therapy 5, 6
• Administer electrolyte-containing solutions (isotonic saline or similar) subcutaneously into the thighs, abdomen, back, or arms using small-gauge needles 5, 6
• Never use electrolyte-free or hypertonic solutions subcutaneously as these cause severe adverse effects in 2.5% of cases 5
• Recombinant human hyaluronidase can increase absorption rates up to 5-fold, making the technique more practical 7
• Potassium chloride up to 34 mmol/L can be safely added to subcutaneous infusions with caution 5

Third-Line: Intravenous Rehydration

• Reserve IV rehydration for patients unable to take oral fluids who require rapid volume replacement or have severe dehydration 4
• Monitor closely for fluid overload, especially in elderly or cardiac patients during IV rehydration 4
• Avoid overaggressive fluid resuscitation which leads to pulmonary, cutaneous, and intestinal edema 4

Special Considerations for Elderly Patients

• Use directly measured serum osmolality >300 mOsm/kg as the diagnostic standard for dehydration in older adults, not skin turgor 1
• If serum osmolality unavailable, use calculated osmolarity (1.86 × [Na+ + K+] + 1.15 × glucose + urea + 14) with threshold >295 mmol/L 1
• Apply moisturizers with high lipid content to maintain skin barrier function in elderly patients 8, 4
• Avoid sedative antihistamines in elderly patients except in short-term or palliative settings 8, 4

Monitoring Response to Treatment

• Reassess skin turgor regularly during rehydration therapy in appropriate age groups to monitor improvement 4
• Monitor vital signs, urine output, mental status, and serum osmolality rather than relying solely on skin turgor 1, 4
• Address underlying causes of dehydration (infection, diarrhea, inadequate intake) while managing fluid status 4

Common Pitfalls to Avoid

• Do not rely on skin turgor alone in older adults—it has poor diagnostic accuracy due to age-related skin changes 1, 9
• Do not use mouth dryness, weight change, urine color, or specific gravity to assess hydration in older adults 1
• Bioelectrical impedance should NOT be used to assess hydration status as it lacks diagnostic utility 1
• Never administer subcutaneous fluids without electrolytes, as this significantly increases adverse event risk 5
