Inhaled corticosteroids (ICSs) are currently used to prevent and treat asthma and recurrent wheezing attacks in children. Fluticasone propionate (FP) is one of the most commonly prescribed ICSs because it is considered effective and well tolerated.

In vitro and animal experiments have shown that the transport and signaling of β2-adrenergic agonists are pH-sensitive. Inhaled albuterol, a hydrophilic β2-adrenergic agonist, is widely used for the treatment of obstructive airway diseases.

To investigate rate, characteristics of acid-base disturbances in patients with chronic kidney disease stage 4, 5 who were diagnosed for the first time. Subjects and methods: 182 patients with chronic kidney disease stage 4, 5 due to some causes without alkalization or replacement therapy within a month. Assessment of acid-base disturbances based on results of arterial blood gas test according to the criteria of Berend K, which include pH, HCO3 - and PaCO2.

Differential Diagnosis To establish the cause of metabolic alkalosis (Table 48-6), it is necessary to assess the status of the extracellular fluid volume (ECFV), the recumbent and upright blood pressure, the serum [K+], and the renin-aldosterone system. For example, the presence of chronic hypertension and chronic hypokalemia in an alkalotic patient suggests either mineralocorticoid excess or that the hypertensive patient is receiving diuretics.

Metabolic Acidosis Metabolic acidosis can occur because of an increase in endogenous acid production (such as lactate and ketoacids), loss of bicarbonate (as in diarrhea), or accumulation of endogenous acids (as in renal failure). Metabolic acidosis has profound effects on the respiratory, cardiac, and nervous systems. The fall in blood pH is accompanied by a characteristic increase in ventilation, especially the tidal volume (Kussmaul respiration). Intrinsic cardiac contractility may be depressed, but inotropic function can be normal because of catecholamine release.

Approach to the Patient: Acid-Base Disorders A stepwise approach to the diagnosis of acid-base disorders follows (Table 48-3). Care should be taken when measuring blood gases to obtain the arterial blood sample without using excessive heparin. Blood for electrolytes and arterial blood gases should be drawn simultaneously prior to therapy, since an increase in [HCO3–] occurs with metabolic alkalosis and respiratory acidosis. Conversely, a decrease in [HCO3–] occurs in metabolic acidosis and respiratory alkalosis.

Adaptation to Hypoxia An important component of the respiratory response to hypoxia originates in special chemosensitive cells in the carotid and aortic bodies and in the respiratory center in the brainstem. The stimulation of these cells by hypoxia increases ventilation, with a loss of CO2, and can lead to respiratory alkalosis. When combined with the metabolic acidosis resulting from the production of lactic acid, the serum bicarbonate level declines (Chap. 48).
