Recommended amounts of intranasal corticosteroids are generally not associated with systemic side effects. Corticosteroids inhibit wound healing. Therefore, use of corticosteroid nasal sprays in patients who have experienced recent nasal septal ulcers, recurrent epistaxis, nasal surgery or trauma, a nasal corticosteroid should be used with caution until healing has occurred. In pregnancy, recommended doses of intranasal corticosteroids are safe and effective. == References ==
Acute Metabolic Acidosis
Bicarbonate therapy is generally administered In patients with severe acute acidemia (pH < 7.11), or with less severe acidemia (pH 7.1-7.2) who have severe acute kidney injury. Bicarbonate therapy is not recommended for people with less severe acidosis (pH ≥ 7.1), unless severe acute kidney injury is present. In the BICAR-ICU trial, bicarbonate therapy for maintaining a pH >7.3 had no overall effect on the composite outcome of all-cause mortality and the presence of at least one organ failure at day 7. However, amongst the sub-group of patients with severe acute kidney injury, bicarbonate therapy significantly decreased the primary composite outcome, and 28-day mortality, along with the need for dialysis. Chronic Metabolic Acidosis
For people with Chronic Kidney Disease, treating metabolic acidosis slows the progression of chronic kidney disease. Dietary interventions for treatment of chronic metabolic acidosis include base-inducing fruits and vegetables that assist with reducing the urine net acid excretion, and increase TCO2. Recent research has also suggested that dietary protein restriction, through ketoanalogue-supplemented vegetarian very low protein diets are also a nutritionally safe option for correction of metabolic acidosis in people with Chronic Kidney Disease.Currently, the most commonly used treatment for chronic metabolic acidosis is oral bicarbonate. The NKF/KDOQI guidelines recommend starting treatment when serum bicarbonate levels are <22 mEq/L, in order to maintain levels ≥ 22 mEq/L.
