Hyponatremia!
Plasma Na+ concentration is a measure of concentration and NOT of VOLUME
Disorders of plasma sodium concentration reflect an underlying disorder involving water homeostasis: an impaired ability of the kidneys to excrete free water due to the action of ADH
Urine Osmolarity: the appropriate response to hypo-osmolar serum (<275) is to excrete a
maximally dilute urine (Uosm <100); non-dilute urine (Uosm> 100) is evidence of impaired
free water exchange via appropriate or inappropriate ADH
Urine Na: appropriate renal response is to enhance Na reabsorption (UNa <10); when UNa
>20– evidence of either normal effective circulating volume or an intrinsic Na-wasting problem

BOARD REVIEW WITH THE CHIEFS
DUST OFF THOSE OLD STETHOSCOPES, FOLKS. IT’S TIME TO START GEARING UP FOR
BOARDS. HERE IS A QUICK PEARL WE LEARNED THIS WEEK:
Q: 76 y/o female is admitted for a 1-week history of progressive weakness, nausea, and
anorexia. She lives independently but has become bedridden and confused during the
past 3 days. Her past medical history is notable for hypertension for which she takes
enalapril and chlorthalidone, which was started 2 weeks ago. Physical exam and
laboratory studies are consistent with hypotonic hyponatremia with a serum sodium of
111 meq/L. Therapy with 3% saline initiated and her mentation rapidly improves to
baseline.
Repeat labwork 10 hours later reveals the following: Serum Na of 121, Urine Na of 48
(from 82 on admission), Urine osmolality of 206 (from 486 on admission) and a urine
output of 400mL/h since admission. What is the next most appropriate treatment?
5% dextrose in water. This patient has hypotonic hyponatremia associated with altered
mentation, which typically warrants prompt correction with 3% saline. However, the increase in her
serum sodium level following treatment exceeds the recommended initial target of 4 to 6 meq/L (4-6
mmol/L) over the first 24 hours. The high urine volume and decreasing urine osmolality following
hypertonic saline administration reflect a rapid water diuresis and suggest that the serum sodium
level will likely continue to increase, placing the patient at increased risk for osmotic demyelination
syndrome (ODS). Therefore, hypotonic solutions such as 5% dextrose in water should be
administered with close follow-up of the serum sodium level, with the goal of maintaining the serum
sodium level in the range of 114 to 116 meq/L (114-116 mmol/L) in the first 24 hours.
Sterns RH, Hix JK. Overcorrection of hyponatremia is a medical emergency. Kidney Int. 2009;76
(6):587-589. PMID: 19721422
Sickle Cell Care
Updates
1. Watch for Epic patient alerts describing
individualized care plans unique to some
patients
2. The recommended safe maximum bolus of
IV hydromorphone is 2mg every 30
minutes for up to 4 doses
3. Keep an eye out for a new
and improved order set
coming soon.
Please direct questions about
care of patients with Sickle Cell
Disease at UCMC to Dr. Hyon
