WALLACE ROBERT KEITH HERBERT BENSON, AND ARCHIE F. WILSON. A kzkeful h@mwtabtkc pI$iologic state, Am. J. Physiol. 22 l(3) : 795-799. 197 1 .-Mental states can markedly alter physiologic function. Hypermetabolic physiologic states, with in creased oxygen consumption, accompany anticipated stressful situations. Hypometabolic physiologic changes, other than those occurring during sleep and hiberna...

Analytic expressions for plasma total titratable base, base excess (DeltaCB), strong-ion difference, change in strong-ion difference (DeltaSID), change in Van Slyke standard bicarbonate (DeltaVSSB), anion gap, and change in anion gap are derived as a function of pH, total buffer ion concentration, and conditional molar equilibrium constants. The behavior of these various parameters under respir...

Introduction: Gattinoni et al. have recently introduced a new parameter: the “alactic base excess” (ABE). ABE is equivalent to number of strong acids, other than lactate, which are present in plasma abnormal concentrations, negative being associated with higher mortality sepsis. Hemoperfusion (HPF) an extracorporeal procedure that involves passage blood through adsorption cartridge, where solut...

abstractbackground: the survival rate of preterm and low-birth-weight (lbw) infants depends on various factors such as birth weight, gestational age, and quality of care. the present study aimed at evaluating the survival rate of preterm and lbw infants, predictive factors, and the risk of mortality in three training hospitals of mashhad and tabriz cities.methods: this prospective, cohort study...

AIM To investigate the relation between common acid-base parameters and blood lactate concentrations and their prognostic importance in sick, ventilated neonates. METHODS Two hundred and seventy eight serial simultaneous measurements of arterial acid-base status and blood lactate concentrations were carried out in 75 mechanically ventilated neonates with indwelling arterial catheters (gestati...

Stewart in 1983 (Can J Physiol Pharmacol 1983: 61: 1444) reintroduced plasma buffer base under the name "strong ion difference" (SID). Buffer base was originally introduced by Singer and Hastings in 1948 (Medicine (Baltimore) 1948: 27: 223). Plasma buffer base, which is practically equal to the sum of bicarbonate and albuminate anions, may be increased due to an excess of base or due to an incr...
