Table 2. Arterial Blood Gases, Hematocrits, Plasma Sodium, and Potassium Concentrations before and after Intravenous Administration of Bupivacaine 2.0 mg/kg

Values are mean ± SD.

p  H^a= arterial blood p  H; Pa^CO2= arterial carbon dioxide partial pressure; Pa^O2= arterial oxygen partial pressure; HCO³= bicarbonate; Hct = hematocrit; Na = plasma sodium; K = plasma potassium; BUP = bupivacaine.
