Última Acid-base balance in sheep with experimentally induced acute ruminal lactic acidosis Arq. Bras. Med. Vet. Zootec. Sabes,A.F.; Girardi,A.M.; Zangirolami Filho,D.; Bueno,G.M.; Oliveira,J.A.; Marques,L.C.. ABSTRACT This study aimed to investigate the changes in the acid-base balance of sheep with experimentally induced acute ruminal lactic acidosis (ARA). Ten ewes orally received 15 grams of sucrose per kilogram of body mass. Arterial blood samples for blood gas analysis were obtained at the following intervals: before the induction of ARA (control), and 2, 4, 6, 8, 10, 12, 16, 20, 24, 28, 32, 36, 48, 72, 96, 120 and 144 hours after sucrose administration. Urine samples for pH measurement were obtained at the following times: -15 days, -7 days, and immediately before sucrose administration, then at 24, 48, 72, 96, 120 and 144 hours. Thereafter, both blood and urine samples were obtained on the 2nd, 3rd, and 4th following weeks. From 4 hours after the...

Metabolic acidosis has profound effects on vascular tone. This study investigated the in vivo effects of acute metabolic acidosis (AMA) and chronic metabolic acidosis (CMA) on hemodynamic parameters and endothelial function. CMA was induced by ad libitum intake of 1% NH4Cl for 7 days, and AMA was induced by a 3-h infusion of 6 M NH4Cl (1 mL/kg, diluted 1:10). Phenylephrine (Phe) and acetylcholine (Ach) dose-response curves were performed by venous infusion with simultaneous venous and arterial blood pressure monitoring. Plasma nitrite/nitrate (NOx) was measured by chemiluminescence. The CMA group had a blood pH of 7.15±0.03, which was associated with reduced bicarbonate (13.8±0.98 mmol/L) and no change in the partial pressure of arterial carbon dioxide...

Ano: 2016 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2016000200604 Clinical utility of standard base excess in the diagnosis and interpretation of metabolic acidosis in critically ill patients BJMBR Park,M; Taniguchi,L.U; Noritomi,D.T; Libório,A.B.; Maciel,A.T; Cruz-Neto,L.M. The aims of this study were to determine whether standard base excess (SBE) is a useful diagnostic tool for metabolic acidosis, whether metabolic acidosis is clinically relevant in daily evaluation of critically ill patients, and to identify the most robust acid-base determinants of SBE. Thirty-one critically ill patients were enrolled. Arterial blood samples were drawn at admission and 24 h later. SBE, as calculated by Van Slyke's (SBE VS) or Wooten's (SBE W) equations, accurately diagnosed metabolic acidosis (AUC = 0.867, 95%CI = 0.690-1.043 and AUC = 0.817, 95%CI = 0.634-0.999, respectively). SBE VS was weakly correlated with total SOFA (r = -0.454, P < 0.001) and was similar to SBE W (r = -0.482, P < 0.001). All acid-base variables were...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2008000300011 Effect of chloride dialysate concentration on metabolic acidosis in aintenance hemodialysis patients BJMBR Marques,F.O.; Libório,A.B.; Daher,E.F.. Hyperchloremia is one of the multiple etiologies of metabolic acidosis in hemodialysis (HD) patients. The aim of the present study was to determine the influence of chloride dialysate on metabolic acidosis control in this population. We enrolled 30 patients in maintenance HD program with a standard base excess (SBE) ≤2 mEq/L and urine output of less than 100 mL/24 h. The patients underwent dialysis three times per week with a chloride dialysate concentration of 111 mEq/L for 4 weeks, and thereafter with a chloride dialysate concentration of 107 mEq/L for the next 4 weeks. Arterial blood was drawn immediately before the second dialysis session of the week at the end of each phase, and the Stewart physicochemical approach was applied. The strong ion gap...

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2010001000012 Effect of metabolic acidosis on renal tubular sodium handling in rats as determined by lithium clearance BJMBR Menegon,L.F.; Figueiredo,J.F.; Gontijo,J.A.R.. Systemic metabolic acidosis is known to cause a decrease in salt and water reabsorption by the kidney. We have used renal lithium clearance to investigate the effect of chronic, NH4Cl-induced metabolic acidosis on the renal handling of Na+ in male Wistar-Hannover rats (200-250 g). Chronic acidosis (pH 7.16 ± 0.13) caused a sustained increase in renal fractional Na+ excretion (267.9 ± 36.4%), accompanied by an increase in fractional proximal (113.3 ± 3.6%) and post-proximal (179.7 ± 20.2%) Na+ and urinary K+ (163.4 ± 5.6%) excretion when compared to control and pair-fed rats. These differences occurred in spite of an unchanged creatinine clearance and Na+ filtered load. A lower final body weight was observed in the acidotic (232 ± 4.6 g) and pair-fed (225 ±...
