“…The decreased MAP in the those two groups remained at values lower than those at 0 min value (p<0.05). In a similar manner, SAP and DAP in the beagles given 5 or 15 ml/kg-HSS were significantly decreased at 2 min after the initiation of the fluid infusion, The rPV values were calculated from Hb and Ht, using Greenleaf's formulas [7,18]. Level of significance (p<0.05) indicated: a: vs 5 ml/kg ISS, b: vs 2.5 ml/kg HSS and c: vs 5 ml/kg HSS.…”

“…Several possibilities concerning the mechanisms of beneficial effects of a HSS intravenous (IV) infusion have been proposed, as follows. One possibility is the expansion of circulating volume [2,3,8,10,13,14,[18][19][20]. A 140 ml infusion of HSS can drew 575 ml and 285 ml of water from interstitial and intracellular fluid compartments, respectively; the expanding plasma volume thus reached 1,000 ml [8].…”

“…Changes in the relative plasma volume (rPV) were calculated from Hb and Ht, using accepted formulas [7,[18][19][20]. The serum osmotic pressure was determined by the freezing point depression method, using a one-ten osmometer (Fiske Association, Norwood, MA, U.S.A.).…”

ABSTRACT. The effect of an intravenous (IV) infusion of hypertonic saline solution (HSS; 7.2%, 2,400 mOsmol/kg·H 2 O) was evaluated by serum electrolyte concentrations and osmotic pressure in the anesthetized beagles. Sixteen beagles were assigned to 3 experimental groups (2.5, 5 or 15 ml/kg of HSS IV infusion) or a control group (5 ml/kg of isotonic saline solution (ISS) IV infusion) and were monitored for 120 min after the initiation of fluid infusion. The relative plasma volume (rPV) in the 5 ml/kg and 15 ml/kg HSS groups progressively expanded to 143.1 ± 7.4% at 3 min and 156.4 ± 5.9% at 5 min after the initiation of the fluid infusion, respectively. Significant increases were not produced by ISS and 2.5 ml/kg HSS infusion. The serum sodium and chloride concentrations in the ISS group were not altered. The 5 ml/kg HSS infusion induced transient high osmotic and sodium levels, and the serum sodium concentration remained under the 160 mM/l after the completion of the HSS infusion. However, the 15 ml/kg HSS infusion induced a constant high osmotic level (340.5-352.8 mOsmol/kg·H 2 O) and hypernatremia (161.4-174.5 mM/l) from 10 to 90 min after the initiation of the fluid infusion. The 15 ml/kg HSS infusion induced significant decreases in the partial pressure of oxygen (PaO 2 ), reaching 63.7 ± 8.0 mmHg at 120 min after the initiation of the fluid infusion compared with an immediately before fluid infusion value. On the basis of these findings, 5 ml/kg HSS infusion can be safely administered to healthy beagles for expanding the plasma volume without inducing hypernatremia. A 5 ml/kg HSS infusion is thus recommended for the initial field resuscitation of dogs.-KEY WORDS: arterial blood pressure, canine (beagle), hypernatremia, hypertonic saline solution, plasma volume.

“…Some venous blood samples were used to determine the hemoglobin concentration (Hb) and hematocrit value (Ht) with an automatic cell counter (MEK-6248: Nihon Koden). Changes in the relative plasma volume (rPV) were calculated from Hb and Ht, with accepted formulas [5,21]. Relative changes in base excess (rBE) were derived from the following equation: rBE = BE samp -BE pre , where BE samp and BE pre were BE concentrations in each sampling and pre point, respectively.…”

ABSTRACT. After intravenous (IV) infusion of various volumes of 1.35%-isotonic sodium bicarbonate solution (ISB), acid-base equilibrium, blood pressure, plasma volume and biochemical parameters in healthy Holstein calves were studied. Four calves each were randomly assigned to the low-dose (LD; IV infusion of 5 ml/kg ISB), middle-dose (MD; IV infusion of 10 ml/kg ISB) and the high-dose groups (HD; IV infusion of 15 ml/kg ISB). Administration volumes of ISB in the LD, MD and HD groups were decided based on the first half volumes of 5, 10 and 15 mEq of base requirement by the acceptable equation. Systemic, pulmonary artery and central venous pressures, cardiac output and plasma osmotic pressure were not changed by ISB infusion and remained constant throughout the experiment for all groups. There was good correlation ( r 2 = 0.950) between relative changes in base excess and infused volume of bicarbonate (y=2.491x). The coefficient of distribution for bicarbonate ions was calculated to be 0.401 (=1/2.491). Therefore, it is suggested that a value of 0.4 would be most appropriate when calculating the base requirements in calves. Therefore, the first half volumes of ISB correcting base deficits of 5, 10 and 15 mEq in calves were estimated to be 6, 12 and 18 ml/kg, respectively. On the basis of the findings in this study, ISB may be used to correct metabolic acidosis without altering the plasma osmotic pressure, hemodynamic status and respiratory function in the calves. KEY WORDS: acid-base equilibrium, calf, coefficient of distribution, metabolic acidosis, sodium bicarbonate.

“…Person et al [14] suggested that hypotonic saline solution with 2.5% dextrose appeared to be the most appropriate solution when moderate dehydration of children had to be corrected immediately by fluid infusion. Our previous study indicated that hypotonic Ringer's solution with 2.5% dextrose (RS) did not change the balance of plasma electrolyte and induced a proper reabsorption rate of glucose in the renal system [15]. Metabolic acidosis is also a common occurrence in calves with diarrhea.…”

ABSTRACT. The effects of intravenous infusion of hypotonic lactated Ringer's (LR: n=14) on plasma volume and venous blood gases were compared to those of hypotonic Ringer's solutions (RS: n=7) in diarrheic Japanese Black breed calves with metabolic acidosis. V enous blood samples were collected immediately before and after, and at 24 hr after the fluid infusion therapy. The LR and RS infusions increased relative plasma volume to 147.1 ± 25.5% and 134.2 ± 18.6%, respectively, just after the fluid therapy. The LR infusion induced an increase in the BE value (+5.1 ± 4.8 mM) at 24 hr compared to that of RS. LR infusion should be explored as a treatment for dehydration and moderate metabolic acidemia caused by naturally occurring diarrhea in calves.
