Bacteriemia asociada a catéteres venosos centrales no tunelizados en niños en hemodiálisis crónica / Bacteremia associated with non-tunneled central venous catheters in children undergoing chronic hemodialysis

Introducción. La infección asociada a catéter venoso central (CVC) es la principal complicación que presentan los pacientes en hemodiálisis en los que se usa este tipo de acceso. Objetivo. Estimar la incidencia de bacteriemia asociada a CVC no tunelizado, analizar la frecuencia de agentes causales y explorar factores de riesgo asociados en niños en hemodiálisis. Población y métodos. Estudio retrospectivo realizado en niños en hemodiálisis por CVC no tunelizado entre el 1 junio de 2015 y el 30 de junio de 2019. Para evaluar factores de riesgo predictores de bacteriemia asociada a CVC, se realizó regresión logística. Los factores de riesgo independiente se expresaron con odds ratio con sus respectivos intervalos de confianza del 95 %. Se consideró estadísticamente significativo un valor de p <0,05. Resultados. En este estudio se incluyeron 121 CVC no tunelizados. La incidencia de bacteriemia fue de 3,15 por 1000 días de catéter. El microorganismo aislado con mayor frecuencia fue Staphylococcus epidermidis (16 casos, 51,5 %). La infección previa del catéter fue el único factor de riesgo independiente encontrado para el desarrollo de bacteriemia asociada a CVC no tunelizado (OR: 2,84; IC95%: 1,017,96; p = 0,04). Conclusiones. El uso prolongado de los CVC no tunelizados para hemodiálisis crónica se asoció con una incidencia baja de bacteriemia. Los gérmenes grampositivos predominaron como agentes causales. La presencia de infección previa del CVC aumentó en casi 3 veces el riesgo de bacteriemia asociada a CVC en nuestra población pediátrica en hemodiálisis.

Introduction. Central venous catheter (CVC)-related infection is the main complication observed in patients undergoing hemodialysis with this type of venous access. Objective. To estimate the incidence of non-tunneled CVC-related bacteremia, analyze the frequency ofcausative agents, and explore associated risk factors in children undergoing hemodialysis. Population and methods. Retrospective study in children receiving hemodialysis via a non-tunneled CVC between June 1 st, 2015 and June 30 th, 2019. A logistic regression was carried out to assess risk factors that were predictors of CVC-related bacteremia. Independent risk factors were described as odds ratios with their corresponding 95% confidence interval (CI). A value of p < 0.05 was considered statistically significant. Results. A total of 121 non-tunneled CVCs were included in this study. The incidence of bacteremia was 3.15 per 1000 catheter-days. The most commonly isolated microorganism was Staphylococcus epidermidis(16 cases, 51.5%). Prior catheter infection was the only independent risk factor for the development of bacteremia associated with non-tunneled CVC (OR: 2.84, 95% CI: 1.01­7.96, p = 0.04). Conclusions. Prolonged use of non-tunneled CVCs for chronic hemodialysis was associated with a low incidence of bacteremia. Gram-positive microorganisms prevailed among causative agents. A prior CVC infection almost trebled the risk for CVC-related bacteremia in our pediatric population receiving hemodialysis.

Catheter-related thrombosis in a neonatal intensive care unit: a case-control study / Trombose relacionada a cateter em unidade de terapia intensiva neonatal: um estudo de caso-controle

INTRODUCTION: Catheter-related thrombosis (CRT) accounts for most thrombotic events in the neonate. OBJECTIVE: Investigate CRT frequency, association with days of catheter use until diagnosis, and number of catheters used, in a single-center Neonatal Intensive Care Unit. METHODS: A case-control study that included 14 cases and 42 controls. Data collection occurred between January 2017 and December 2020 in a public NICU. Crude odds ratios (COR) were calculated. The study complied with ethical standards from national guidelines. RESULTS: Two hundred and ninety-four neonates used central venous catheters, of which 14 (4.7%) were diagnosed with CRT. Catheter in use when diagnosis was made was centrally inserted central catheters in 8 (57.1%). Before diagnosis, the cumulative duration of catheter use was 34.5 days and the median number of catheters used was three. A higher SNAPPE-II (COR 1.03; 95% CI 1.01-1.06; p=0.03), cumulative days of catheter use >30 (COR 19.11; 95% CI 2.28-160.10; p=0.007) and number of catheters used ≥3 (COR 7.66; 95% CI 1.51-38.70; p=0.01) were associated with CRT. CONCLUSION: CRT cases were associated with clinical severity; number of catheters and cumulative days of catheter use. We suggest that screening for thrombosis should be performed in neonates who need a long time of catheter use and more than three catheters. Reducing the duration and number of venous catheters used will help to reduce CRT.

INTRODUÇÃO: A trombose relacionada ao cateter (TRC) é responsável pela maioria dos eventos trombóticos no neonato. OBJETIVO: Investigar a frequência da TRC, a associação com os dias de uso do cateter até o diagnóstico e o número de cateteres utilizados em uma Unidade de Terapia Intensiva Neonatal unicêntrico. MÉTODOS: Estudo caso-controle que incluiu 14 casos e 42 controles. A coleta de dados ocorreu entre janeiro de 2017 e dezembro de 2020 em uma UTIN pública. Foram calculadas razões de chances brutas (COR). O estudo respeitou os padrões éticos das diretrizes nacionais. RESULTADOS: Duzentos e noventa e quatro neonatos utilizaram cateter venoso central, dos quais 14 (4,7%) foram diagnosticados com TRC. O cateter em uso no momento do diagnóstico foi o cateter central inserido centralmente em 8 (57,1%). Antes do diagnóstico, o tempo acumulado de uso do cateter foi de 34,5 dias e a mediana do número de cateteres utilizados foi de três. Um maior número de dias de uso do cateter >30 (COR 19,11; IC 95% 2,28-160,10; p=0,007) e número de cateteres utilizados >3 (COR 7,66; IC 95% 1,51-38,70; p=0,01). CONCLUSÃO: Os casos de TRC foram associados à gravidade clínica; número de cateteres e dias cumulativos de uso do cateter. Sugerimos que o rastreamento de trombose seja realizado em neonatos que necessitem de longo tempo de uso do cateter e mais de três cateteres. Reduzir a duração e o número de cateteres venosos usados ajudará a reduzir a TRC.

Objective:To evaluate the effect of nursing specialist nurses′ assistance on the ability of nursing home nurses to maintain venous catheter under the vision of combination of medical care and nursing care, providing reference for carrying out specialized nursing assistance work in grassroots hospitals.Methods:This study was an experimental study. According to Miller′s pyramid theory, a model of specialist nurse assistance was established with specialized technology as the core. From January to December 2021, three nursing hospitals in Suzhou were assisted. Convenience sampling method was used to investigate the ability of intravenous catheter maintenance, the incidence of central venous catheter maintenance defects, the incidence of central venous catheter complications and unplanned extubation, and the satisfaction of doctors and patients before and after help.Results:Totally 86 nurses were included, aged (33.17 ± 2.31) years old. After the help, the theoretical and operational skill scores of nurses in the nursing home were (89.77 ± 2.11) and (92.75 ± 1.62) points, respectively, which were significantly higher than those before the help (60.84 ± 2.71) and (79.81 ± 1.68) points, and the differences were statistically significant ( t=-84.96, -52.12, both P<0.05). Among the maintenance defects of central venous catheter in nursing homes, incomplete labeling, film wrapping, blood seepage, catheter discounting, non-standard film fixing, and incomplete information of extended care were 9.95% (21/211), 8.53% (18/211), 2.84% (6/211), 6.16% (13/211), 4.74% (10/211), 2.37% (5/211) after help, all lower than 50.57% (89/176), 43.18% (76/176), 14.20% (25/176), 25.57% (45/176), 18.18% (32/176), 11.93% (21/176) before help. The differences were statistically significant ( χ2 values were 14.00 to 77.81, all P<0.05). The incidence of medical adhesive related skin injury, catheter obstruction complications and unplanned extubation were 4.44% (4/90), 3.33% (3/90) and 2.22% (2/90), respectively, which were lower than 20.51% (16/78), 15.38% (12/78) and 11.54% (9/78) before help. The differences were statistically significant ( χ2=8.81, 6.06, 4.50, all P<0.05). Doctors′ satisfaction with nurses and patients′ satisfaction with nursing work were 96.43%(27/28) and 93.75%(45/48), respectively, both higher than 71.43%(20/28) and 72.73%(32/44) before help, and the differences were statistically significant respectively ( χ2=4.77, 5.97, both P<0.05). Conclusions:From the perspective of combination of medical care and nursing care, the maintenance and assistance of intravenous catheters by the team of intravenous therapy nurses in nursing hospitals can effectively reduce the incidence of central venous catheter complications and unplanned extubation, improve the maintenance ability of intravenous catheters of nurses in nursing hospitals, and help to improve the quality of nursing care in nursing hospitals.

Objective To explore the application efficacy and safety of oblique ultrasound-guided techniques in PICC puncture,in order to provide guidance and references for clinical application.Methods Through convenient sampling,654 patients from a tertiary A hospital in Zhejiang Province from March to December 2022 were selected as the study subjects.The random numbers were generated through Excel table functions and they were randomly grouped into 3 groups:A,B,and C.The ultrasound short axis method,long axis method,and oblique axis method were employed to guide PICC puncture catheterization,respectively.The success rate of PICC puncture,the number of subcutaneous adjustments of the puncture needle,puncture time,and the occurrence of puncture complications(such as hematoma,puncture of the posterior wall of blood vessels,accidental injury to arteries,and accidental injury to nerves)were recorded during the catheterization process in 3 groups.Results A total of 654 patients completed the study,including 215 in group A,219 in group B,and 220 in group C.The success rate of first-time puncture in the group C(86.36％)was higher than that in group A(73.95％)and group B(63.93％),and there was a statistically significant difference among 3 groups(P＜0.001).The subcutaneous adjustment frequency of the puncture needle was 1(1,1)in group C,1(1,2)in group A,and 1(1,2)in group B.The difference between 3 groups was statistically significant(P＜0.001);the puncture time of group C was shorter than that of group A and group B,and the difference was statistically significant(P＜0.001).There was a statistically significant difference in the puncture time between 3 groups(P＜0.017);the pairwise comparison of the number of subcutaneous needle adjustments and the success rate of a puncture between 3 groups showed that there was a statistical difference between group C and group A,and between group C and group B(P＜0.017),while there was no statistical difference between group A and group B(P＞0.017).There was statistical significance(P＜0.05)among 3 groups in terms of complications such as accidental nerve injury and puncture of the contralateral vascular wall by puncture needle,but there was no statistical significance in terms of accidental arterial injury and hematoma occurrence among 3 groups.Conclusion Compared with the short axis approach and the long axis approach,the ultrasound oblique axis approach guided PICC puncture has statistical differences in the success rate of a puncture and the incidence of puncture complications,etc.It is recommended to use the ultrasound oblique axis approach during PICC puncture.

Correlation between lung allocation score and early death risk of patients with idiopathic pulmonary fibrosis after lung transplantation / 器官移植

Objective To analyze the correlation between the lung allocation score (LAS) and the risk of early death and complications in patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 275 patients with IPF were retrospectively analyzed. The correlation between LAS and the risk of early death in IPF patients after lung transplantation and the correlation between LAS and complications at postoperative 1 year was assessed by univariate and multivariate Cox regression analyses. Results Among 275 recipients, 62, 83, 95 and 108 cases died within postoperative 30, 90, 180 and 365 d, respectively. LAS was correlated with 30-, 90-, 180- and 365-d fatality of IPF patients (all P<0.05), whereas it was not correlated with the incidence of primary graft dysfunction (PGD) and acute kidney injury (AKI) at 365 d after lung transplantation (both P>0.05). Conclusions LAS is correlated with the risk of early death of IPF patients after lung transplantation. While, it is not correlated the incidence of PGD and AKI early after lung transplantation. Special attention should be paid to the effect of comprehensive factors upon PGD and AKI.

Catheter-associated infection and influencing factors in anti-tumor chemo-therapy treated patients after indwelling peripherally inserted central ca-theter:analysis based on random forest model / 中国感染控制杂志

Objective To analyze the influencing factors for catheter-associated infection(CAI)in chemotherapy treated patients after indwelling peripherally inserted central catheter(PICC)based on a random forest model.Methods 400 tumor patients who received chemotherapy and PICC were selected and divided into the training set(n=300)and the test set(n=100)in a 3∶1 ratio through computer-generated random number.Patients in the training set were subdivided into the non-infection group and the infection group based on the occurrence of infec-tion.Clinical data from two groups of patients were compared.Influencing factors for the occurrence of CAI after PICC were analyzed with multivariate logistic regression model and the integrated classification algorithm of random forest model,and the predictive performance of the two methods was compared.Results Among 300 chemotherapy treated patients in the training set,32 cases(10.67％)experienced CAI.Compared with the non-infection group,patients in the infection group had more single punctures for catheterization,longer PICC retention time,larger pro-portion of catheter movement,larger proportion of complication with diabetes,higher frequency of dressing chan-ges,lower white blood cell count and immune function(all P＜0.05).PICC retention time,catheter movement,complication with diabetes,dressing change frequency,white blood cell(WBC)and immune function were inde-pendent influencing factors for CAI after PICC(all P＜0.05).The random forest model showed that ranking by the importance of different influencing factors was as following:PICC retention time,catheter movement,complication with diabetes,WBC,dressing change frequency and immune function.The integrated classification algorithm of random forest model for predicting the occurrence of CAI in chemotherapy treated patients showed that the area un-der the receiver operating characteristic(ROC)curve(AUC)was 0.872,which had better prediction performance compared with the logistic regression model(AUC=0.791).Conclusion PICC retention time,catheter movement,complicated with diabetes,dressing change frequency,WBC level and immune function are independent influencing factors for CAI in chemotherapy treated patients.The integrated classification algorithm of random forest model can be used to predict CAI in chemotherapy treated patients,and its prediction performance is better than that of the logistic regression model.

Objective: to analyze the effectiveness of peripherally inserted central catheter insertion techniques in preventing the occurrence of complications related to this device in newborns. Method: a paired and network systematic literature review and meta-analysis, with its search carried out in seven databases and in the Grey Literature, including randomized and non-randomized clinical trials. The risk of bias was assessed using the Cochrane Risk of Bias 2 and Risk of Bias In Non-randomized Studies of Interventions tools. Certainty of the evidence was assessed by means of the Grading of Recommendations Assessment, Development and Evaluation. A meta-analysis was carried out with the aid of the R statistical program. Results: eight studies with 1,126 newborns were included and six insertion techniques were identified: intracavitary electrocardiogram; intracavitary electrocardiogram associated with ultrasound; ultrasound; formula; anatomical landmark; and modified anatomical landmark. Five techniques significantly decreased primary tip malpositioning when compared to the control ( p <0.05). Intracavitary electrocardiogram significantly and more effectively reduced arrhythmias, general complications and phlebitis; the technique that used a formula also reduced general complications. Infection, infiltration, secondary tip malpositioning, catheter rupture, thrombosis, occlusion and catheter-associated skin lesion were not significantly preventable events. Conclusion: intracavitary electrocardiogram and use of the formula were the most effective techniques in reducing complications.

Causas anatómicas inusuales de malposición de catéteres venosos centrales / Unusual anatomical causes of malposition of central venous catheters

Resumen: La malposición de los catéteres venosos centrales se asocia a importantes riesgos, a menudo infraestimados. Aunque se han descrito algunos factores que pueden favorecer la malposición, generalmente su causa no llega a diagnosticarse y parece ser de origen multifactorial. Presentamos dos casos de malposición de catéteres venosos centrales motivadas por causas anatómicas inusuales, diagnosticadas en el perioperatorio. En el primer caso, se diagnostica una agenesia de vena cava superior en el transcurso de una sustitución mitral por esternotomía, que lógicamente se asocia con una malposición de la vía central insertada. La utilización de catéteres y dispositivos a través de venas yugulares y subclavias en pacientes con esta infrecuente patología implica importantes limitaciones y complicaciones potenciales graves. En el segundo caso, la existencia de un bocio no diagnosticado provoca la malposición bilateral y simultánea de dos catéteres venosos canalizados, en el contexto de una situación de emergencia, en ambas venas yugulares internas.

Abstract: Malposition of central venous catheters is associated with important and underestimated risks. Although some factors have been related with malposition, its cause is generally not diagnosed, and it seems to have multifactorial origin. We present two cases of central venous catheter malposition due to unusual anatomical causes, diagnosed in the perioperative period. In the first case, superior vena cava agenesis was diagnosed during mitral replacement by sternotomy, which was logically associated with malposition of the inserted central line. The use of catheters and devices through jugular and subclavian veins in patients with this infrequent pathology is associated with important limitations and serious potential complications. In the second case, an undiagnosed goiter causes bilateral and simultaneous malpositioning of two inserted central venous catheters, in the context of an emergency situation, in both internal jugular veins.

Central venous-to-arterial CO2 difference as a biomarker of outcome in children who underwent surgery for congenital heart disease / Diferencia arteriovenosa de CO2 como biomarcador de desenlace en niños operados de cardiopatías congénitas

Abstract Background: In congenital heart surgery, low cardiac output syndrome (LCOS) is a major cause of morbidity in the immediate post-operative period. A decrease in cardiac output leads to an increase in tissue oxygen consumption. Several biomarkers such as venous oxygen saturation (SvO2), arteriovenous oxygen difference (DavO2), and lactate can assess tissue perfusion in the presence of LCOS. Recently, central venous to arterial CO2 difference (ΔCO2) has been proposed as a biomarker of tissue ischemia that could be used as a predictor of death in neonatal patients. This study aimed to analyze the relationship between ΔCO2 and immediate post-operative outcomes in pediatric patients undergoing congenital heart surgery and its correlation with DavO2, SvO2, and lactate. Methods: We conducted a longitudinal study of patients aged 0-18 years who underwent congenital heart surgery with or without cardiopulmonary bypass at the Instituto Nacional de Pediatría, from March 2019 to March 2021. Results: Eighty-two patients were included; the median age was 17 months. About 59% had a ΔCO2 ≥ 6 mmHg. Patients with ΔCO2 ≥ 6 mmHg had a vasoactive-inotropic score > 5 (p < 0.001), DavO2 > 5 mL/dL (p = 0.048), and lactate > 2 mmol/L (p = 0.027), as well as a longer hospital stay (p = 0.043). Patients with ΔCO2 > 6 mmHg and vasoactive-inotropic score ≥ 10 were 12.6 times more likely to die. Conclusion: ΔCO2 is a good marker of tissue hypoperfusion and outcome in the post-operative period of congenital heart surgery.

Resumen Introducción: En la cirugía cardiaca de malformaciones congénitas, el síndrome de bajo gasto cardiaco (SBGC) es una de las principales causas de morbilidad en el postoperatorio inmediato. La caída del gasto cardiaco aumenta el consumo de oxígeno en los tejidos. Varios biomarcadores, como la saturación venosa de oxígeno (SvO2), la diferencia arteriovenosa de oxígeno (DavO2) y el lactato han sido utilizados como indicadores hipoperfusión tisular en presencia de SBGC. Recientemente, la diferencia arteriovenosa de CO2 (ΔCO2) se ha propuesto como otro biomarcador de isquemia tisular que podría utilizarse como predictor de muerte en pacientes en edad neonatal. El objetivo de este estudio fue analizar la relación entre la ΔCO2 y la evolución postoperatoria de pacientes pediátricos operados de cardiopatías congénitas y correlacionarlo con la DavO2, SvO2 y lactato. Métodos: Se realizó un estudio longitudinal en pacientes de 0 a 18 años operados de corazón con empleo de bomba de circulación extracorpórea en el Instituto Nacional de Pediatría. Resultados: Se incluyeron 82 pacientes; la mediana de edad fue de 17 meses. El 59% presentó un ΔCO2 > 6 mmHg. Los pacientes con un ΔCO2 > 6 mmHg mostraron un puntaje de inotrópicos > 5 (p < 0.001), DavO2 > 5 mL/dL (p = 0.048) y lactato > 2 mmol/L (p = 0.027), así como mayor estancia hospitalaria (p = 0.043). Los pacientes con ΔCO2 > 6 mmHg y un puntaje de inotrópicos ≥ 10 presentaron una probabilidad de muerte 12.6 veces mayor. Conclusiones: El ΔCO2 en el periodo postoperatorio de una cirugía cardiaca congénita es un buen marcador de hipoperfusión tisular y de desenlace.

Cross-sectional study of quality of life in relation with vascular access in hemodialysis patients. Study in a hospital and a satellite center

Introduction: Vascular access for hemodialysis (HD) is essential for the patient. Even though Arteriovenous fistula (AVF) is the preferred access, in certain age groups, the central venous catheter (CVC) may provide advantages. This study aims to investigate the quality of life related to vascular access. Methods: Cross-sectional study including patients from a hospital, a home HD unit and a satellite hemodialysis center. Clinical data was collected from the patients, who went through a quality-of-life questionnaire SF12 and a Vascular Access Questionnaire (VAQ). Results: 91 patients participated, mostly male (70 %), with a mean age of 68.9 ± 16.2 years. AVF was the current vascular access in 60.4 %, the rest used a CVC. Home HD was performed in 12.1 % of patients and 76 % started it via CVC. Regarding patients who have had both AVF and CVC, 58 % prefer AVF and only 26.5 % of current CVC carriers would have a new AVF, mostly due to fear of pain (52 %). Most people (72.5 %) reported having received sufficient information, with no differences between both accesses. The SF12 results showed no differences between patients with AVF or CVC. Regarding the VAQ, patients with AVF were more satisfied with the social aspect (p = 0.036) and complications (p = 0.006). Conclusion: Patients with AVF had better outcomes than those using CVC regarding complications and social aspects. These differences are not attributable to a worse overall quality of life status of CVC patients. Most patients with CVCs refuse to go through a new AVF for fear of puncture pain.

Introducción: el acceso vascular para la hemodiálisis (HD) es esencial para el paciente. Aunque la fístula arteriovenosa (FAV) es el acceso preferido, en ciertos grupos de edad el catéter venoso central (CVC) puede aportar ventajas. Este estudio pretende investigar la calidad de vida relacionada con el acceso vascular. Métodos: el estudio transversal incluye pacientes del hospital, de una unidad de HD domiciliaria y de un centro de hemodiálisis periférico. Se recogieron datos clínicos de los pacientes que contestaron el cuestionario de calidad de vida SF12 y Cuestionario de Acceso Vascular (VAQ). Resultados: 91 pacientes, en su mayoría varones (70 %), con una edad media de 68,9 ± 16,2 años. La FAV era el acceso vascular actual en el 60,4 %. La HD domiciliaria se realizó en el 12,1 % de los pacientes y el 76 % la inició mediante CVC. En cuanto a los pacientes que han tenido tanto FAV como CVC, el 58 % prefiere la FAV y sólo el 26,5 % de los actuales portadores de CVC se sometería a una nueva FAV, sobre todo por miedo al dolor (52 %). La mayoría de las personas (72,5 %) declararon haber recibido suficiente información, sin diferencias entre ambos accesos. Los resultados del SF12 no mostraron diferencias según el acceso. En cuanto al VAQ, los pacientes con AVF estaban más satisfechos con el aspecto social y las complicaciones. Conclusión: los pacientes con FAV tuvieron mejores resultados en comparación con los que utilizaron CVC en cuanto a complicaciones y aspectos sociales, sin deberse a un peor estado general de la calidad de vida. La mayoría de los pacientes con CVC se niegan a someterse a una nueva FAV por miedo al dolor de la punción.

CLINICAL PROFILE IN PATIENTS WITH CEREBRAL VENOUS SINUS THROMBOSIS IN TERTIARY CARE HOSPITAL: A CROSS SECTIONAL STUDY

CVST often creates challenges regarding diagnosis among physicians, due to the nonspeci?c symptoms and countless presentation and absence of uniform symptoms. This study aims to understand current knowledge about CSVT including its pathogenesis, etiogenesis, clinical profile, diagnosis, and treatment. A Methods: descriptive cross-sectional study was conducted in the department of neurology at tertiary care hospital, Mumbai between January, 2021 and June 2022. This study was approved by institutional ethics committee. All patients who were more than 18 years with diagnosis of cerebral venous sinus thrombosis, admitted to critical care unit of neurology department were included in this study and those with bleeding disorder and prior anticoagulation therapy, already diagnosed with CVST were excluded. CVST was 3 times more common in females than in m Results: ales and the age group of 21 to 30 years was more common affected. Headache was the most common symptom seen and papilledema was the most common sign. In females puerperium was the main cause of CVST. Superior sagittal sinus and right transverse sinus were the most common sinuses involved as seen on Computed tomography(CT)venography/Magnetic resonance venography(MRV)and common finding was venous infarct. The mortality rate was 16%. Patients with Isolated intracranial hypertension syndrome(ICH) had good outcome. Variables like age ?35 years, GCS score of <8 and coma at presentation were associated with poor prognosis. CVST has a wide range of cli Conclusion nical presentation. The prognosis is good in CVST but early diagnosis with treatment and care is required in patients with poor prognostic factors.

Ultrasound-guided central venous access for patients in the Intensive Care Unit in prone position: report of three cases

Abstract The prone position is extensively used to improve oxygenation in patients with severe acute respiratory distress syndrome caused by SARS-CoV-2 pneumonia. Occasionally, these patients exhibit cardiac and respiratory functions so severely compromised they cannot tolerate lying in the supine position, not even for the time required to insert a central venous catheter. The authors describe three cases of successful ultrasound-guided internal jugular vein cannulation in prone position. The alternative approach here described enables greater safety and well-being for the patient, reduces the number of episodes of decompensation, and risk of tracheal extubation and loss of in-situ vascular lines.
