Comparison of ultrasound guidance and palpation technique for femoral artery catheterization in children undergoing cardiac surgery.

OBJECTIVE: The aim of this study was compare the palpation technique and ultrasound-guidance for femoral artery catheterization in pediatric patients undergoing surgery for congenital heart disease. MATERIALS AND METHODS: This prospective and randomized controlled study included American Society of Anesthesiologists III-IV 40 children who underwent congenital heart surgery. The patients were divided into two groups; ultrasound-guided catheterization group and palpation-guided catheterization group. Demographic and clinical characteristics of the patients, access time, success rate, number of attempts, first-attempt success, number of trials, and failed cannulations were recorded. RESULTS: The diameter of the femoral artery was significantly shorter, access time and numbers of trials were significantly lower, and first-attempt success rate was significantly higher in the US group. The complication rate was significantly higher in the P group. The number of failed catheterization was higher in the P group. Total cost required for the procedure was significantly lower in the US group. CONCLUSION: We found that ultrasound-guided arterial catheterization increases the success rate and the number of successful catheterizations, while reducing the overall procedure time, incidence of complications, and cost. Therefore, we believe that the use of ultrasound guidance in arterial catheterization in pediatric cardiac surgery would be a better choice.

OBJETIVO: El objetivo de este estudio fue comparar la técnica de palpación y ecoguiado para el cateterismo de la arteria femoral en pacientes pediátricos operados de cardiopatías congénitas. MATERIALES Y MÉTODOS: Este estudio prospectivo, aleatorizado y controlado incluyó a 40 niños ASA III-IV que se sometieron a cirugía cardíaca congénita. Los pacientes se dividieron en 2 grupos; Grupo de cateterismo guiado por ecografía y grupo de cateterismo guiado por palpación. RESULTADOS: El diámetro de la arteria femoral fue significativamente más corto, el tiempo de acceso y el número de intentos fueron significativamente menores y la tasa de éxito del primer intento fue significativamente mayor en grupo estadounidense. La tasa de complicaciones fue significativamente mayor en el grupo P. El número de cateterismos fallidos fue mayor en el grupo P. El costo total requerido para el procedimiento fue significativamente menor en el grupo de EE. CONCLUSIONES: Encontramos que el cateterismo arterial guiado por ultrasonido aumenta la tasa de éxito y el número de cateterismos exitosos, al tiempo que reduce el tiempo total del procedimiento, la incidencia de complicaciones y el costo. Por tanto, creemos que el uso de guía ecográfica en cateterismo arterial en cirugía cardiaca pediátrica sería una mejor opción.

Clinical characterisation and management outcome of obstetric patients following intensive care unit admission for COVID-19 pneumonia.

This study aims to examine the clinical characteristics and mortality-related factors of obstetric patients, who were taken to the intensive care unit due to Coronavirus Disease 2019 (COVID-19). This study included 31 patients in the peripartum period with COVID-19 pneumonia, followed up in the intensive care unit (ICU) from March 2020 to December 2020. Symptoms, laboratory values, intensive care unit duration of stay, complications, the requirement of non-invasive and invasive mechanical ventilation, and mortality were recorded. The mean age was 30.7 ± 6.2 years and the mean gestational age was 31.1 ± 6.4 weeks. Among the patients, 25.8% had a fever, 87.1% had a cough, 96.8% had dyspnoea and 77.4% had tachypnoea. Seventeen patients (54.8%) had mild, 6 (19.4%) had moderate and 8 (25.8%) had severe pulmonary involvement on computed tomography. Sixteen (51.6%) patients required high-frequency oscillatory ventilation, 6 (19.3%) patients required continuous positive airway pressure, and 5 (16.1%) patients required invasive mechanical ventilation. Sepsis complicated by septic shock and multiorgan failure occurred in 4 patients and all of them died. The ICU duration of stay was 4.9 ± 4.3 days. We have found that older maternal age, obesity, high LDH, AST, ALT, ferritin, leukocyte, CRP, and procalcitonin values, and severe lung involvement were mortality-related factors.Impact statementWhat is already known on this subject? Pregnant women are in the high-risk group for Covid-19 disease and its complications. Although most pregnant women are asymptomatic, severe infection-related hypoxia can cause serious foetal and maternal problems.What do the results of this study add? When we examined the literature, we found that the number of studies on pregnant women with severe Covid-19 infection was limited. For this reason, with our study results, we aim to contribute to the literature by determining the biochemical parameters and patient-related factors associated with severe infection and mortality in pregnant patients with severe Covid-19 infection.What are the implications of these findings for clinical practice and/or further research? With our study results, predisposing factors for the development of severe Covid-19 infection in the pregnant patient population and biochemical parameters that are early indicators of severe infection were determined. In this way, pregnant women in the high-risk group can be followed closely and the necessary treatments can be started quickly so disease-related complications and mortality can be reduced.

Acute Kidney Injury in Intensive Care Unit Patients with Coronavirus Disease 2019.

OBJECTIVE: The incidence of acute kidney injury during the hospital stay in patients with coronavirus disease 2019 varies between 8% and 17% in studies. This rate is at the highest levels among the critical patient group monitored in the intensive care unit (23% [14-35%]). In this study, we aimed to assess the incidence of acute kidney injury development, effective factors, and clinical outcomes of patients monitored in the intensive care unit due to coronavirus disease 2019. METHODS: A total of 801 patients were analyzed. Patients were divided into 2 groups as those developing acute kidney injury (n = 408) and those not developing acute kidney injury (n=393). Patients developing acute kidney injury were staged according to the Kidney Disease Improving Global Outcomes criteria. RESULTS: In all patients, the mortality rate was 65.2%. The mortality rate for those developing acute kidney injury was identified to be high by a statistically significant degree compared to those not developing acute kidney injury. The mortality rate in Kidney Disease Improving Global Outcomes criteria stage 1 was 81.3%, in stage 2 was 88.3%, and in stage 3 was 91.5%. The frequency of diabetes mellitus type 2, coronary artery disease, and chronic obstructive pulmonary disease in the group developing acute kidney injury was found to be statistically significantly higher. We have found positive correlations between acute kidney injury development and age, sex, history of diabetes mellitus, and ferritin levels in the multivariate analysis. CONCLUSIONS: The development of acute kidney injury in intensive care unit patients with coronavirus disease 2019 is associated with increased mortality. Therefore, predisposing factors should be determined and effective treatment strategies should be established in the early period.
