Background: The postpartum hemorrhage is still remaining a leading cause of maternal mortality, especially in developing countries. Objective: We aimed to determine the efficacy using tranexamic acid vaginal delivery avoid and reduce blood loss hospital stay. Patients methods: A prospective-randomized clinical trial study was conducted on 92 pregnant women that were prepared for delivery. The...

BACKGROUND The association of mortality and poor outcome with reduced levels of hemoglobin (Hb) and hematocrit (Hct) in patients admitted for ischemic stroke was recently demonstrated. The mechanisms behind this have remained unclear. AIMS Here, we aimed to investigate a putative association between low Hb and Hct levels and infarct growth. METHODS All consecutive patients who received intr...

We determined the overall pulmonary diffusing capacity (DL) and the diffusing capacities of the alveolar membrane (Dm) and the red blood cell (RBC) segments (De) of the diffusional pathway for O2 by using a two-dimensional finite-element model developed to represent the sheet-flow characteristics of pulmonary capillaries. An axisymmetric model was also considered to assess the effect of geometr...

Frank,Andreas O., C. J. Charles Chuong, and Robert L. Johnson.Afinite-element model of oxygen diffusion in the pulmonary capillaries. J. Appl. Physiol. 82(6): 2036–2044, 1997.—We determined the overall pulmonary diffusing capacity (DL) and the diffusing capacities of the alveolar membrane (Dm) and the red blood cell (RBC) segments (De) of the diffusional pathway for O2 by using a two-dimensiona...

Polycythemia vera (PV) is a chronic myeloproliferative disorder whose major morbidity and mortality are thrombohaemorragic events. Current guidelines advise maintaining hematocrit (HCT) level below 45% in males and 42% in females. Such targets lean on pathophysiological reasoning, while evidence from ECLAP and PVSG-01, the two largest prospective studies in this disease, suggests no difference ...

BACKGROUND Mathematical models have been used to describe the factors that affect cell salvage (CS) and normovolemic hemodilution (ANH). Here, the CS and ANH models were used to compare these two techniques alone or in combination with each other. STUDY DESIGN AND METHODS Variables used for a hypothetical patient included an estimated blood volume of 5000 mL, a presurgery hematocrit (Hct) of ...

Background: Deferring the umbilical cord clamping produces more satisfactory neurological and hematological outcomes. Another alternative for deferred is milking. Objectives: This study aimed to evaluate different placental transfusion techniques in terms of parameters term neonates. Methods: observational included 120 infants assigned groups 60 seconds (DCC), cut milking four times with a spee...

In this paper, we propose a dynamical model for pulsatile flow estimation of an iRBP. Noninvasive measurements of the motor power (V I) and pump impeller rotational speed (ω) were acquired from the pump controller and used together with blood hematocrit (HCT ) values as inputs to the model. A circulatory mock loop was operated with different aqueous glycerol solutions, mimicking different value...

In this study, we report hematocrit and plasma chemistry values for adult captive collared scops owls (Otus lettia) and crested serpent eagles (Spilornis cheela hoya). In particular, we address the gender-specific differences within these values. We measured hematocrit (HCT) and plasma chemistry values for uric acid (UA), plasma urea nitrogen (BUN), total protein (TP), albumin (ALB), glucose (G...

Numerous studies have focused on alterations in plasma volume (PV) on interventions like quiet standing, exercise, or heat stress. However, no method seems capable of truly estimating the PV alteration. Therefore, an attempt was made to validate commonly used indexes of PV changes. Quiet standing was used to cause graded PV reductions estimated from hemoglobin and hematocrit (Hb/Hct) and from s...
