“…There was no correlation between arterial and venous pO 2 and SaO 2 values in studies investigating agreement between artery–vein pO 2 and SO 2 values. [161819] Furthermore, there was no correlation between arterial and venous pO 2 values in our study ( r = 0.120). No correlation was found between arterial and venous values ( r = 0.100).…”

“…found a strong correlation between pH values of ABG and central VBG in patients who underwent coronary artery bypass graft surgery and followed up in the intensive care unit in the postoperative period. [18] Because of the strong correlation between arterial and venous pH, pCO 2 , and HCO 3 values, they formulated equations for finding arterial values from venous values. [18] In our study, there was also a strong positive correlation between arterial–venous HCO 3 and pCO 2 values ( r = 0.9334 and 0.725, P < 0.001, respectively) with 95% confidence level.…”

OBJECTIVES: Obesity hypoventilation syndrome (OHS) and some neuromuscular diseases (NMD) present with hypercapnic respiratory failure. Arterial blood gas (ABG) analysis is important in the diagnosis, follow-up, and treatment response of these diseases. However, ABG sampling is difficult in these patients because of excessive subcutaneous fat tissue, muscle atrophy, or contracture. The aim of this study is to investigate the value of venous blood gas (VBG), which is an easier and less complicated method, among stable patients with OHS and NMD. METHODS: The study included stable OHS and NMD patients who had been previously diagnosed and followed up between March 2017 and May 2017 in the outpatient clinic. ABG was taken from all patients in room air, and peripheral VBG was taken within 5 min after ABG sampling. RESULTS: Thirty-six patients with OHS and 46 patients with NMD were included in the study. There was a moderate positive correlation between arterial and venous pH values for all patients ( r s = 0.590, P < 0.001). There were a strong and very strong positive correlations between arterial and venous pCO 2 and HCO 3 values ( r s = 0.725 and r s = 0.934, respectively) ( P < 0.001). There was no correlation between arterial and venous pO 2 and saturation values. There was an agreement in Bland–Altman method for the values of ABG and VBG (pH, pCO 2 , and HCO 3 ). CONCLUSIONS: There was a correlation between ABG and VBG values (pH, pCO 2 , and HCO 3 ). VBG parameters (pH, pCO 2 , and HCO 3 ) can be used safely instead of ABG parameters which have many risks, during treatment and follow-up of patients with OHS and NMD.

“…Second, the used calcium index is different: ionized calcium in the present study versus serum calcium in other studies, while the ionized state is biologically active. Several studies have investigated the relationship of venous and arterial blood gas parameters in critically ill human patients (Ak et al., 2006 ; Awasthi et al., 2013 ; Esmaeilivand et al., 2017 ; Kelly et al., 2001 ; Khan et al., 2010 ; Treger et al., 2010 ) and in rodent models (Schwarzkopf et al., 2013 ; Son et al., 2010 ) demonstrating the good correlations between them. Last, the onset time of patients is different: less than 4.5 h in the present study versus more than 4.5 h in other studies.…”

Background and purpose The relationship between ionized calcium and prognosis of ischemic stroke is controversial. We aim to determine the relationship of admission ionized calcium levels with acute ischemic stroke (AIS) after intravenous thrombolysis (IVT). Methods Consecutive anterior circulation AIS patients treated with recombinant tissue plasminogen activator (rt‐PA) were retrospectively enrolled. According to ionized calcium quartiles, the patients were divided into four groups and clinical data were analyzed between groups. Ionized calcium was entered into logistic regression analysis in two models, separately: model 1, calcium as a continuous variable (per 1‐mmol/L increase), and model 2, calcium as the four‐categorized variable (being collapsed into quartiles: Q1–Q4). Early neurologic improvement (ENI) was defined as improvement of four or more points at 24 h after intravenous rt‐PA, while long‐term good outcome as the modified Rankin Scale (mRS) 0–1 at 90 days. Results A total of 546 patients met the study criteria (mean age was 63.51 ± 11.26 years and 365 [66.8%] were men). The median admission National Institute of Health Stroke Scale was 9 (range 4 to 15). When not adjusted, in model 1: ionized calcium was related to good outcome (odds ratio [OR] 69.061, 95%CI: 1.638–2911.111, p=0.027), but not ENI (OR 14.097, 95%CI: 0.133–1492.596, p=0.266); in model 2: compared with Q4, while good outcome was less common in Q1 (OR 0.623, 95%CI: 0.388–0.999, p=0.049). After adjusting for confounding factors, calcium in Q2 (OR 0.502, 95%CI: 0.253–0.997, p=0.049) was independently associated with ENI, but no matter as a continuous variable or categorized variable, ionized calcium displayed no association with a good outcome. Conclusion The current results found that ionized calcium might be associated with early neurological improvement, but had no association with 3 months' outcome in anterior circulation AIS patients after IVT.

“…En general los gases venosos centrales y arteriales periféricos han mostrado una buena correlación en variables como pH, HCO3-, BE y algunos electrolitos como el sodio o el potasio, encontrando diferencias en la correlación entera saturación de oxígeno y CO2, estas diferencias son las bases de la utilidad de su estimación como predictores de resultados clínicos, este comportamiento no se ha demostrado en el presente estudio para la diferencia de lactato (27)(28)(29).…”

Introducción: La identificación temprana de hipoperfusión tisular es clave para guiar el manejo en pacientes en choque. El interés en obtener una valoración rápida y precisa de la perfusión tisular en el paciente crítico, ha llevado a estudiar diferentes productos metabólicos, sin embargo, ninguno satisface las necesidades sobre el enfoque y manejo de esta condición. La hiperlactatemia es un factor independiente de mortalidad y por ello, el desarrollo de parámetros como la diferencia arterio-venosa de lactato tendrían un valor agregado..Objetivo: evaluar la utilidad pronóstica de la diferencia arterio-venosa de lactato como predictor de mortalidad en pacientes críticamente enfermos.Métodos: estudio de prueba diagnóstica, realizado en las UCIs de la ESE Hospital Universitario del Caribe y Gestión Salud IPS, de enero/2017-enero/2018. Se tomaron muestras de gases arteriales-venosos centrales al ingreso, 12 y 24 horas de estancia en UCI. Se determinó el rendimiento diagnóstico del delta CO2, depuración arterial de lactato, lactato sérico y diferencia arterio-venosa de lactato como predictores de mortalidad.Resultados: se evaluaron 103 pacientes críticos, 49 fallecieron (47.5%). El choque séptico fue el estado más frecuente (57.2%). El delta de CO2 al ingreso mostró AUC de 0.53, el lactato de ingreso AUC 0.57, la depuración arterial de lactato exhibió un AUC de 0.52 y la diferencia arterio-venosa de lactato tuvo AUC de 0.50, con valores de p no estadísticamente relevantes.Conclusión: la diferencia arterio-venosa de lactato es un parámetro clínico con utilidad limitada para predecir mortalidad en la población global de pacientes ingresados a la UCI.
