Serum calcium levels should be corrected for serum albumin before
determining dose. Corrected calcium= serum calcium + 0.8 (4 - serum
albumin). Dosage: Moderate hypercalcemia (12- 13.5 mg/dl): 60 to 90 mg.
Severe hypercalcemia (> 13.5 mg/dl): 90 mg. The manufacturer recommends that
the repeat dose not be given sooner than 7 days after the initial dose in
order to allow full response to this dose. MOA: biphosphonate
compound-inhibits bone resorption (anti-osteoclast activity). Has little
effect on bone remineralization. Relative potency of biphosphonate agents:

Incremental doses slightly increase magnitude of blockade and significantly increase
the duration of action. Cautions: Increases in HR, BP and excessive salivation and sweating
may occur. Concurrent use of corticosteroids will decrease pancuronium
effectiveness and may increase risk and severity of myopathy resulting in
prolonged flaccid paralysis following discontinuation of neuromuscular
blocking agent. |

General guidelines - Review the disclaimer
Treatment of hypokalemia: Level < 2.5:
(life-threatening):
(a) ECG monitoring necessary (transfer to ICU)
(b) Give KCL at 20 to 40 meq/hr depending on severity
(c) Monitor K+ levels hourly
(d) Decrease rate to max of 20 meq/hr when patient is no longer in
immediate danger (eg normal ECG, or level > 2.5)
K+ level: 2.5 to 3.0:
(a) ECG monitoring recommended
(b) Infuse K+ at 10-20 meq/hr x 2 hrs (ICU) or 10 meq/hr x 2-4 hrs
(floors).
(c) Order K+ levels q2h (ICU) q4h (floor).
(d) Repeat infusion as above if K+ < 3.0
(e) Consider oral replacement if patient is asymptomatic K+ level
K+ level: 3 to 3.5: Oral therapy
recommended unless npo. Give 20 to 40 meq po bid-tid. Follow levels
closely.
General info:
*Dextrose solutions containing K+ may cause transient worsening of
hypokalemia and should be avoided if possible.
*In the majority of cases (not critical) K+ rate of infusion should not
exceed 10 meq/hr.
*The amt of K+ to be replaced is difficult to estimate, therefore,
frequent K+ levels should be obtained.
*Extreme caution should be used in patients with renal failure (reduce
rate of administration).
*Maximum rate without cardiac monitoring: 20 meq/hr
*The maximum single oral dose should not exceed 50 meq (gastric
irritation, potential for cardiac arrest, etc.)
*hypokalemia potentiates the effects of digoxin. If ischemic heart disease
or PVC's are absent and patient not on digoxin, one may elect to withhold
replacement of K+ until level< 3.2.
Treatment of
hyperkalemia (K+ level > 5):
Therapeutic approach:
**Rule out pseudohyperkalemia: (hemolyzed specimen, severe leukocytosis,
fist clenching during phlebotomy, lab error.) Obtain ECG or rpt K+
level.
**Stop all K+ intake (IV/PO) **Check pH, corrent acidosis if present. For
every 0.1 decline in pH from 7.4(nml) results in an increase in K+ of 0.6
meq/L.
**Check Ca++, Mg++, BUN/creat.
**Identify underlying cause if necessary (eg renal failure,
mineralocorticoid deficiency etc).
Emergencies (cardiac toxicity or K+ > 6.1) (Note: the following
measures are instituted immediately & f/b kayexalate. Withhold Calcium
gluconate if K+ < 6.5. Patient must be on monitor) (1) Give Calcium
gluconate 1-2g over 15-30 minutes. Used to counteract the neuromuscular
and cardiac effects of hyperkalemia. May give more rapidly if ECG has
deteriorated to a sine wave or worse-give 0.5 to 1g Calcium gluconate
over 3 to 5 minutes.
(2) Administer 50ml (1 amp) Sodium bicarb IV over 5min. Repeat as
necessary-especially if patient is acidotic (common in renal failure).
Increased risk in patients with CHF. Onset: immediate Duration: 2-3 hr.
Normally repeated in 15 minutes if ECG changes persist. ECG changes: Tall
thin T-waves, Prolonged PR-interval, widened QRS, loss of P-wave.
(3) Admin 1 amp of 50% dextrose IVP over 5 min plus 10u insulin IV. Repeat
in 15min if serum K+ still toxic. Alternatively, admin 500 ml 10% dext +
10-15u insulin over 1 hr. Glucose is unnecessary if blood sugar is
elevated. Onset: 15-45 minutes. Duration: 4-6hrs. (4) Administer 15 to 50g
of kayexalate po now. May repeat q6h. (If npo: give 25-50g by rectal
retention enema (retain for 1hr). Oral: 1 gram/ 1 meq K+. Onset:
1-2hrs. Duration: 4-6hrs. Use caution in patients who cannot tolerate even
a small increase in sodium load (eg severe CHF; marked edema; etc.) Note:
Never administer kayexalate alone for symptomatic hyperkalemia because of
the slow onset.
Patients with K+ < 6 meq/L with no ECG changes: Administer
kayexalate as above. Consider lasix 20 to 40mg IVpush in the
volume-overloaded patient or when inadequate K+ excretion contributes to
hyperkalemia.
