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.

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.

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.

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.

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.

Design and application of a central venous pressure measurement tool / 中华危重病急救医学

Central venous pressure (CVP) reflects the comprehensive condition of effective blood volume, cardiac function and vascular tone. Clinical monitoring of CVP can indirectly understand and evaluate the dynamic changes of blood volume in patients, and provide a reference for patients to venous fluid. At present, the traditional manual measurement method is widely used for measurement, which has some shortcomings such as zero shift, cumbersome operation (requires two health care workers to cooperate). In order to overcome the above problems, the author invented a new fixable CVP measurement tool and obtained the national utility model patent (ZL 2021 2 1451705.7). The tool is mainly composed of a base plate, a movable frame and a measuring department, etc. When used, the base plate is placed into the back of the patient and pressed and fixed, the movable frame is adjusted, the zero point is found, and the measurement data is read from the measuring department. It has the advantages of simple and convenient operation, small measurement error, wide applicability (different body types) and so on, which is suitable for clinical promotion.

Discussion on the zero-calibration and the zero line in the measurement of central venous pressure and invasive arterial blood pressure / 中华危重病急救医学

Objective:To figure out the timing of zeroing and the location of the zero line in the central venous pressure (CVP) monitoring and invasive arterial blood pressure (IBP) monitoring, and to provide scientific and accurate data for patients management.Methods:The liquid vessel models were used to simulate the pressure measurement process of the continuous pressure monitoring system. Based on the theory of fluid mechanics and the knowledge of blood pressure physiology and cardiovascular anatomy, the composition and influencing factors of the pressure in the fluid-filled catheter system during the zeroing and placing the transducer in the zero line of CVP and IBP, were analyzed.Results:The pressure in the liquid-filled catheter system was composed of atmospheric pressure, the pressure of pumping bag, the gravity of the water column (the vertical distance between the liquid level of Murphy's dropper and pressure transducer, ΔH), and the resistance of tube wall. This pressure value is set as a pressure of 0 mmHg (1 mmHg ≈ 0.133 kPa). In the process of pressure measurement, when the pressure transducer was placed at a horizontal position of 10 cm below the highest liquid level of the vessel, the pressure measured at different catheter tip positions was all 10 cmH 2O (1 cmH 2O ≈ 0.098 kPa); When the pressure transducer was placed at the horizontal position of the highest liquid level of the vessel, the measured pressure is 0 mmHg. Conclusion:Zeroing should repeatedly be performed only when one or more conditions (atmospheric pressure, pressure of pumping bag, gravity of ΔH water column and resistance of tube wall) are changed. In the measurement process, the pressure transducer should be placed at the zero line position at any time to eliminate the influence of hydrostatic pressure and to ensure the objective and accurate value.

Complications of central venous catheterization and risk factors in Pediatric Intensive Care Unit of Xi 'an Children's Hospital / 中国基层医药

Objective:To analyze the incidence of complications of central venous catheterization and risk factors in the Pediatric Intensive Care Unit of Xi'an Children 's Hospital.Methods:The clinical data of 310 children who underwent central venous catheterization in the Pediatric Intensive Care Unit of Xi 'an Children's Hospital from June 2020 to February 2021 were retrospectively analyzed. The incidence of complications of central venous catheterization and risk factors were analyzed.Results:A total of 334 central venous catheters were used in 310 chidren. Among the 310 children who underwent central venous catheterization, 102 children (30.54%) had complications related to central venous catheterization. The complications related to central venous catheterization included catheter infection (13.17%), catheter malposition (8.38%), exudation at the puncture site (4.79%), catheter occlusion (2.99%), accidental removal (0.60%), and central venous thrombosis (0.60%). Central venous catheters were removed in 82 children (24.55%) because of complications. There was a significant difference in the incidence of central venous thrombosis among three surgical approaches: femoral vein, internal jugular vein, and subclavian vein ( χ2 = 7.06, P = 0.029). Longer time for catheterization resulted in a higher incidence of complications, including catheter-related infection ( χ2 = 7.17, P = 0.028), puncture point exudation and obstruction ( χ2 = 8.59, P = 0.014), central venous thrombosis ( χ2 = 6.78, P = 0.034). Regression analysis showed that suture shedding and bleeding at the insertion sites were the main risk factors for catheter-related complications (suture shedding OR = 4.85, P = 0.001; bleeding at the insertion sites OR = 1.83, P = 0.008). Conclusion:The most common complications of central venous catheterization in the Pediatric Intensive Care Unit of Xi'an Children's Hospital include catheter-related infection, catheter malposition, and puncture site exudation. Risk factors for complications during catheter retention include suture shedding and bleeding at the insertion sites.

Expert consensus on perioperative nursing standards for pediatric kidney transplantation / 器官移植

Pediatric kidney transplant recipients differ from adult counterparts in primary disease, physiology, psychology, organ function and immune status and their perioperative treatment and nursing management are different from those of adult kidney transplantation. To standardize holistic perioperative nursing regimens for pediatric kidney transplantation, Surgery Nursing Committee of Shanghai Nursing Association organized national medical and nursing experts in the fields of transplantation to jointly draft "expert consensus on perioperative nursing standards for pediatric kidney transplantation " (abbreviated as "consensus"). After three rounds of online expert inquiry, all revised opinions were jointly discussed combined with literature evidence, and the expert consensus was finally reached. The highlights of perioperative treatment and nursing care for pediatric kidney transplantation were summarized and stated, including preoperative evaluation, preoperative and postoperative nursing care, which were of scientific and practical value.

Application of remote ischemic preconditioning combined with controlled low central venous pressure in hepatectomy / 临床肝胆病杂志

Objective To investigate the application effect of remote ischemic preconditioning (RIPC) combined with controlled low central venous pressure (CLCVP) in hepatectomy. Methods A total of 80 patients who underwent elective partial hepatectomy in Yougchuan Hospital Affiliated to Chongqing Medical University from May 2021 to April 2022 were enrolled and divided into control group (group C), CLCVP group (group L), RIPC group (group R), and RIPC+CLCVP group (group RL) using a random number table, with 20 patients in each group. The patients in group L received CLCVP, those in group R received RIPC, and those in group RL received both CLCVP and RIPC. The patients were compared in terms of perioperative general status and the levels of tumor necrosis factor-α (TNFα), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin on preoperative day 1(D0), postoperative day 1(D1), postoperative day 3(D3), postoperative day 5(D5), and postoperative day 7(D7). A one-way analysis of variance or a repeated measures analysis of variance was used for comparison of normally distributed continuous data between groups, and the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between groups; the chi-square test was used for comparison of categorical data. Results Compared with group R, group RL had a significantly shorter time of operation ( H =14.278, P =0.015), a significantly lower total infusion volume ( H =24.175, P =0.001), and a significantly lower estimated blood loss ( H =45.625, P < 0.001). Group and time factors had significant interaction effects on TNFα, ALT, and AST in the four groups ( P < 0.001; P =0.010; P =0.012). Group RL had a significantly lower level of TNFα than group L on D1( P < 0.001) and D3( P < 0.001). Group RL had a significantly lower level of ALT than group L on D1( P =0.008) and D7( P < 0.001). Conclusion For patients undergoing hepatectomy, RIPC combined with CLCVP can effectively reduce intraoperative blood loss, provide a clear surgical field, and shorten the time of operation; meanwhile, it can also inhibit inflammatory response by reducing TNFα, but it cannot effectively alleviate hepatic ischemia-reperfusion injury after hepatectomy under the context of CLCVP.

Three cases of neonatal pericardial effusion related to umbilical venous catheterization / 中华实用儿科临床杂志

A retrospective case review was conducted of 3 cases with umbilical venous catheterization(UVC) related pericardial effusions in the Neonatal Intensive Care Unit of Zhongnan Hospital of Wuhan University from December 2020 to April 2022.All 3 cases were preterm infants with gestational ages of 33 + 4, 31 and 27 + 6 weeks, respectively.UVC was inserted routinely in 24 hours after birth.Three neonates developed tachycardia or bradycardia, dyspnea, decreased oxygen saturation and muffled heart sound at the 1 st to 4 th day after catheterization.Echocardiography indicated pericardial effusion, so the 3 neonates underwent pericardiocentesis and drainage.Among the 3 neonates, 2 cases improved and have good prognosis, 1 case died.UVC can cause pericardial effusion, which occurs mostly in the early stage after catheterization.Pericardial effusion and tamponade should be considered when patients show unexplained sudden clinical deterioration after catheterization, such as dyspnea, cyanosis, tachycardia or bradycardia, etc.Once diagnosed, umbilical vein catheter should be removed in time and pericardiocentesis and drainage should be performed for decompression.Early diagnosis and intervention can effectively improve the prognosis.

Predictive value of Pcv-aCO 2 on left ventricular ejection fraction in myocardial infarction / 中华急诊医学杂志

Objective:To investigate the relationship between central venous-arterial blood carbon dioxide partial pressure difference (Pcv-aCO 2) and left ventricular ejection fraction(LVEF) in acute myocardial infarction. Methods:Clinical data of patients with acute myocardial infarction admitted to the Intensive Care Unit of Fujian Provincial Hospital from November 2019 to October 2021 were retrospectively analyzed. LVEF was measured by bedside echocardiogram. The patients were divided into the normal LVEF group (LVEF ≥ 52%) and decreased LVEF group (LVEF < 52%) according to LVEF. The differences in general information and hemodynamic parameters between the two groups were compared. The normality of the above data was tested by the Jarque-Bera test. Correlation analysis of hemodynamic indices with LVEF was performed. Binary logistic regression was used to analyze the risk factors associated with the decrease in LVEF. The feasibility of diagnosing LVEF decline with Pcv-aCO 2 was assessed using receiver operating characteristic (ROC) curve. Results:Seventy-two patients with acute myocardial infarction were included for analysis, including 25 patients in the normal LVEF group and 47 patients in the decreased LVEF group. Pcv-aCO 2 was significantly higher in the decreased LVEF group than that in the normal LVEF group [(7.13±1.19) mmHg vs. (5.41±1.23) mmHg, P<0.01]. There was a negative correlation between LVEF and Pcv-aCO 2 ( rs= -0.740, P<0.01). The area under the ROC curve for Pcv-aCO 2 was 0.849 (95% CI: 0.758-0.939, P<0.01). The binary logistic regression analysis showed that Pcv-aCO 2 was an independent risk factor for decreased LVEF ( OR=2.251, 95% CI: 1.326-3.820). Conclusions:To a certain extent, the increase of Pcv-aCO 2 can predict the decrease of LVEF in acute myocardial infarction.

Application of body surface markers localization in totally implantable venous access port implantation via internal jugular vein approach / 国际外科学杂志

Objective:To investigate the feasibility of using body surface marker localization method to determine the correct position of catheter tip (lower 1/3 of the superior vena cava or the junction of superior vena cava and right atrium) in totally implantable venous access port (TIVAP) implantation via internal jugular vein approach.Methods:The clinical data of 220 patients who underwent TIVAP implantation in Beijing Tongren Hospital, Capital Medical University from June 2019 to June 2021 were retrospectively analyzed. Among them, 168 patients used the internal jugular vein approach. According to the method implemented for determining the length of central venous catheter (CVC) during the operation, the patients were divided into two groups: 136 patients using the body surface marker localization method were defined as the study group; and the remaining 32 cases treated by the intraoperative X-ray fluoroscopic localization method were defined as the control group. The difference in the excellent or good rate of CVC tip position immediately after implantation and the time of implantation was compared between the two groups. In addition, the correlation between the length of CVC indwelling, height, age, and the distance between the catheter tip and tracheal carina was analyzed for the patients with right and left internal jugular vein catheterization. Kolmogorov-Smirnov test was used for statistical distribution of measurement data. Normal distribution of measurement data was expressed as mean ± standard deviation ( ± s), independent sample t-test was used for comparison between groups. Chi-square test was used for comparison between counting data. With TIVAP catheter indenture length as dependent variable and height as independent variable, Pearson correlation analysis was performed, the relationship equation between ideal catheter indenture length and patient height was analyzed by unitary linear regression. Results:When the CVC tip was located at the second intercostal space, the third sternocostal joint and the third intercostal space, the corresponding probability of being in the correct position was 34.8%, 83.3% and 95.0% respectively. The third sternocostal joint or the third intercostal space had a higher probability of correct CVC tip location than the second intercostal space, and the difference were statistically significant ( P<0.001). Furthermore, there was no significant difference in the possibility of the CVC tip located in the correct position between the third sternocostal joint and the third intercostal space ( P=0.149). Compared with the control group (before adjusting catheter position), the proportion of excellent or good CVC position in the study group was significantly improved (94.1% vs 46.9%), and the difference was statistically significant ( χ2=41.99, P<0.001); while the total operation time was significantly shortened [(33.04±6.69) min vs (42.50±5.54) min], and the difference was statistically significant ( P<0.05). There was a linear correlation between the length of CVC insertion and height. Indwelling catheter length via right internal jugular vein approach (cm) =0.159× height (cm)-1.284 ( r=0.597, r2=0.356, P<0.001); length of catheter indwelling through the left approach (cm) =0.097× height (cm) + 12.139 ( r=0.322, r2=0.104, P=0.020). Conclusions:The third sternocostal joint or the third intercostal space would be the corresponding correct surface landmark of the CVC tip when the body surface marker localization method was adopted during the TIVAP implantation via the internal jugular vein approach. Compared with the intraoperative X-ray fluoroscopy localization, the operation time is significantly shortened with the application of the body surface marker localization method. This technique is simple and easy to master and has high reliability in determining the length of catheter and the position of CVC tip.
