Medical Device-Associated Biofilm Infections and Multidrug-Resistant Pathogens.

Medical devices such as venous catheters (VCs) and urinary catheters (UCs) are widely used in the hospital setting. However, the implantation of these devices is often accompanied by complications. About 60 to 70% of nosocomial infections (NIs) are linked to biofilms. The main complication is the ability of microorganisms to adhere to surfaces and form biofilms which protect them and help them to persist in the host. Indeed, by crossing the skin barrier, the insertion of VC inevitably allows skin flora or accidental environmental contaminants to access the underlying tissues and cause fatal complications like bloodstream infections (BSIs). In fact, 80,000 central venous catheters-BSIs (CVC-BSIs)-mainly occur in intensive care units (ICUs) with a death rate of 12 to 25%. Similarly, catheter-associated urinary tract infections (CA-UTIs) are the most commonlyhospital-acquired infections (HAIs) worldwide.These infections represent up to 40% of NIs.In this review, we present a summary of biofilm formation steps. We provide an overview of two main and important infections in clinical settings linked to medical devices, namely the catheter-asociated bloodstream infections (CA-BSIs) and catheter-associated urinary tract infections (CA-UTIs), and highlight also the most multidrug resistant bacteria implicated in these infections. Furthermore, we draw attention toseveral useful prevention strategies, and advanced antimicrobial and antifouling approaches developed to reduce bacterial colonization on catheter surfaces and the incidence of the catheter-related infections.

An analysis of central venous catheter-related bloodstream infections in patients treated in a Swedish Covid-19 intensive care unit.

Catheter-related bloodstream infection is a well-known, severe complication of central venous catheter insertion. Studies that have evaluated the coronavirus disease 2019 pandemic's influence on the incidence of catheter-related bloodstream infection in intensive care units are limited. Therefore, we conducted a retrospective study on catheter-related bloodstream infection in coronavirus disease 2019 intensive care unit with previously documented low incidence rates to evaluate the pandemic's impact. To evaluate the impact of the coronavirus disease 2019 pandemic on catheter-related bloodstream infection incidence in the intensive care unit. All central venous catheter-inserted patients aged ⩾18 years admitted to the intensive care unit with coronavirus disease 2019 pneumonia were included. The primary outcome was the incidence of catheter-related bloodstream infection, and the secondary outcome was the detection of catheter-related bloodstream infection-causative microorganisms. During the pandemic's first year, 124 patients were admitted, and 203 central venous catheters were inserted. Two patients developed catheter-related bloodstream infection. The incidence of catheter-related bloodstream infection was 0.79/1000 catheter days. The microorganisms responsible for catheter-related bloodstream infection were Staphylococcus epidermidis and Escherichia coli. This study revealed a low incidence of catheter-related bloodstream infection in the coronavirus disease 2019-intensive care unit, thus suggesting that coronavirus disease 2019 is not a risk factor for catheter-related bloodstream infection and indicating the high resilience of well-established routines aimed at catheter-related bloodstream infection prevention.

Mediastinal Haematoma: A Rare Complication Following Insertion of Central Venous Catheter

Mediastinal haematoma is a rare complication following insertion of central venous catheter, with few cases reported in the literature. We report a case of mediastinal haematoma in a 33-year-old male patient with end-stage renal disease. In this patient central venous catheter insertion through the right subclavian vein was attempted on the operation table for renal transplantation but the procedure was abandoned as the attempt was unsuccessful. Post-procedure chest radiograph showed a large mediastinal haematoma occupying right hemithorax that developed as a result of injury to the subclavian vein. Patient was managed conservatively and haematoma completely resolved in four weeks time. This case is being reported to signify the importance of routine obtaining a post-procedure chest radiograph and to state that even large mediastinal haematoma can be managed conservatively in asymptomatic patients.

Association of immediate reinsertion of new catheters with subsequent mortality among patients with suspected catheter infection: a cohort study

BackgroundCentral venous catheter (CVC) insertion complications are a prevalent and important problem in the intensive care unit (ICU), and source control by immediate catheter removal is considered urgent in patients with septic shock suspected to be caused by catheter-related bloodstream infection (CRBSI). We sought to determine the impact of immediate reinsertion of a new catheter (IRINC) on mortality among patients after CVC removal for suspected CRBSI.MethodsA propensity score-matched cohort of patients with suspected CRBSI who underwent IRINC or no IRINC in a 32-bed ICU in a university hospital in China from January 2009 through April 2021. Catheter tip culture and clinical symptoms were used to identify patients with suspected CRBSI. The Kaplan–Meier method was used to analyse 30-day mortality before and after propensity score matching, and adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality in the matched cohort were estimated with Cox proportional hazards models.ResultsIn total, 1,238 patients who had a CVC removed due to suspected CRBSI were identified. Among these patients, 877 (70.8%) underwent IRINC, and 361 (29.2%) did not. Among 682 propensity score-matched patients, IRINC was associated with an increased risk of 30-day mortality (HR, 1.481; 95% CI, 1.028 to 2.134) after multivariable, multilevel adjustment. Kaplan–Meier analysis found that IRINC was associated with the risk of mortality both before matching (P = 0.00096) and after matching (P = 0.018). A competing risk analysis confirmed the results of the propensity score-matched analysis. The attributable risk associated with bloodstream infection was not significantly different (HR, 1.081; 95% CI 0.964 to 1.213) among patients with suspected CRBSI in terms of 30-day mortality compared with that associated with other infections.ConclusionsIn this cohort study, IRINC was associated with higher 30-day mortality compared to delayed CVC or no CVC among patients with suspected CRBSI. A large-sample randomized controlled trial is needed to define the best management for CVC in cases of suspected CRBSI because IRINC may also be associated with noninfectious complications.Trial registration This study was registered with the China Clinical Trials Registry (URL: http://www.chictr.org.cn/index.aspx) under the following registration number: ChiCTR1900022175.

Nursing needs and prevention of complications after central venous catheterisation

Central venous catheterisation (CVC) is an invasive medical procedure with a high risk of complications. The role of the advanced practice nurse, who is aware of the types of CVC, potential risk factors and complication prevention tactics, is important in order to reduce the incidence of CVC complications.
 Objective. The aim of this article is to review the nursing needs and prevention of complications after central venous catheterisation.
 Materials and methods. Seventeen publications up to five years old on the topic were analysed. Articles from 2016 to 2021 were selected from PubMed, UpToDate and Google medical databases. All publications are in English, the text is full and free to access, and the year is no older than 2019. The selected publications describe complications associated with the CVC insertion procedure, choice of catheterisation site, recommendations for nursing staff on CVC care, and prevention of complications.
 Results. The mortality rate from bloodstream infection associated with CVC is approximately 12-25%. Because of the increased risk of infection, it is recommended to avoid femoral vein access. Inadvertent puncture of the artery, air embolism, bleeding and thrombosis are common complications. To reduce the incidence of mechanical complications, ultrasound should be used for diagnostic purposes during the insertion of the central venous catheter. The role of the nurse in the interprofessional team during the CVC insertion procedure is important. The nurse's knowledge and clinical skills are one of the preventive measures, which is significant and important in controlling late infection and aseptic management of CVC.
 Conclusions. 1. Clinical practice of the nurse is based on the regulating legal acts, systematic training of the advanced practice nurse allows to manage the interventional procedure of central venous catheter placement. 2. Diagnostic control is used to reduce the risk of mechanical complications. Aseptic care of the central venous catheter is important for the prevention of infections.

Related Factors of Anemia in Critically Ill Patients: A Prospective Multicenter Study.

Anemia is common in critically ill patients; almost 95% of patients admitted to intensive care units (ICUs) have hemoglobin levels below normal. Several causes may explain this phenomenon as well as the tendency to transfuse patients without adequate cause: due to a lack of adherence to protocols, lack of supervision, incomplete transfusion request forms, or a lack of knowledge about the indications, risks, and costs of transfusions. Daily sampling to monitor the coagulation parameters and the acid–base balance can aggravate anemia as the main iatrogenic factor in its production. We studied the association and importance of iatrogenic blood loss and other factors in the incidence of anemia in ICUs. We performed a prospective, observational, multicenter study in five Spanish hospitals. A total of 142 patients with a median age of 58 years (IQI: 48–69), 71.83% male and 28.17% female, were admitted to ICUs without a diagnosis of iatrogenic anemia. During their ICU stay, anemia appeared in 66.90% of the sample, 95 patients, (95% CI: 58.51–74.56%). Risk factors associated with the occurrence of iatrogenic anemia were arterial catheter insertion (72.63% vs. 46.81%, p-value = 0.003), venous catheter insertion (87.37% vs. 72.34%, p-value = 0.023), drainages (33.68% vs. 12. 77%, p-value = 0.038), and ICU stay, where the longer the stay, the higher the rate of iatrogenic anemia (p-value < 0.001). We concluded that there was a statistical significance in the production of iatrogenic anemia due to the daily sampling for laboratory monitoring and critical procedures in intensive care units. The implementation of patient blood management programs could address these issues.

Reducing central line-associated bloodstream infection in contaminated central venous catheters: case studies of a pediatric contamination guideline

Healthcare organizations have prioritized patient safety and quality improvement efforts to reduce central line-associated bloodstream infections (CLABSIs). Implementation of central venous catheter (CVC) insertion and maintenance bundles have significantly reduced infection rates. Nevertheless, CLABSIs continue to be a significant cause of mortality and morbidity in hospitals, and further efforts are necessary to improve CVC care practices. A hospital-wide committee at a tertiary care pediatric hospital identified gaps in our CVC maintenance practices resulting from CVC contamination events from a patient's body fluids. A lack of published literature on the topic resulted in the need to create an institutional clinical practice guideline (CPG) to develop guidance to mitigate potential CLASBIs from CVC contamination. Utilization of the CVC CPG in all inpatient units and other reduction strategies resulted in a steady decline in our CLABSI rates, particularly in those related to CVC contamination events. Case reports illustrate the effectiveness of the CPG.

Effects of different intraabdominal pressures on internal jugular vein, liver and kidney functions in obese patients undergoing laparoscopic sleeve gastrectomy

Objective The aim of this study was to investigate whether there was a difference in laparoscopic sleeve gastrectomy (LSG) performed with either 10 mmHg or 13 mmHg intraabdominal pressures. Effects of these pressures on the internal jugular vein (IJV) diameter and flow along with the liver and kidney function tests were evaluated. Materials and Methods The patients were divided into two groups with respect to the intraabdominal pressure performed during LSG (either 10 or 13 mmHg). The patients’ age, comorbidities, surgical history, height, weight, body mass index, family history, duration of surgery, length of hospital stay, serum liver and kidney function tests (Urea, creatinine, Aspartate transaminase, Alanine transaminase, Gamma-glutamyltransferase, Alkaline phosphatase, bilirubin) and the right IJV diameter and flow measured by Duplex ultrasound before intubation (t1), 10 min after insufflation (t2), and at the end of insufflation (t3) were recorded. Results Preoperative and postoperative kidney and liver function values of the patients in both groups were within the reference range. In both groups, there was a significant decrease in the IJV diameter and flow measurement values at t2 compared to t1, and a significant increase was observed at t3 compared to t2 (p < 0.05). The mean IJV diameter and flow were significantly higher in the 10 mmHg pressure group compared to the 13 mmHg group (p < 0.05). Conclusion Neither of the peak pressures performed intraabdominal during LSG caused an adverse effect on liver or kidney functions. Our study emphasizes that low insufflation pressure does not have an advantage in terms of liver and kidney functions. But laparoscopic sleeve gastrectomy with low intra-abdominal pressure may be beneficial especially in patients who require central vein catheterization during the operation. We consider that LSG performed with CO2 pneumoperitoneum at 10 mmHg is a safe, effective and feasible method that can facilitate the insertion of the intraoperative central venous catheter due to lesser charges in the IJV diameter and flow compared to the standard technique.

Medical malpractice related to dialysis and vascular access: An analysis of lawsuit judgements in South Korea.

BackgroundHemodialysis is a life-saving renal replacement treatment for patients with chronic kidney disease, but various complications occur during hemodialysis and associated procedures. This study was conducted to analyze the specific characteristics of hemodialysis-related complications and malpractice that have led to legal disputes.MethodsJudgments from cases litigated between 1991 and 2019 due to complications related to hemodialysis or vascular access were analyzed using the database of the Korean Supreme Court Judgment System.ResultsOf 32 dialysis-related litigation cases, 14 cases were dismissed and malpractice was recognized in 18 cases. Among all cases and those in which malpractice was recognized, the most common clinical complication was associated with central venous catheter (CVC) insertion (25.0% and 42.9%, respectively). In 22 of 32 (68.8%) cases, complications occurred before or after (not during) dialysis, and performance error was the most common clinical error leading to legal disputes (58.3%). Complications resulted in death in 59.4% of cases, and CVC-related complications were associated with the largest proportion (63.2%) of deaths.ConclusionsHemodialysis was implicated in various medical disputes, and CVC-related complications were the most common and serious adverse events. Clinicians’ awareness of the incidence and severity of possible complications of hemodialysis procedures should be increased.

Reducing Central Line-Associated Bloodstream Infection in Contaminated Central Venous Catheters: Case Studies of a Pediatric Contamination Guideline

Utilization of the CVC CPG in all inpatient units and other reduction strategies resulted in a steady decline in our CLABSI rates, particularly in those related to CVC contamination events. Case reports illustrate the effectiveness of the CPG.

Management of a Fragmented Angiocatheter During Central Venous Cannulation: A Case Report and Important Lessons

Complications during central venous catheter (CVC) insertion are infrequent with an incidence of 0.1%-1%. We experienced a rare CVC complication with fragmentation of the angiocatheter at its hub during central venous cannulation while utilizing the modified Seldinger technique (ie, wire through the catheter technique). Vascular surgery was emergently required to remove the catheter fragment from the neck. Clinicians must remain vigilant during all aspects of CVC insertion, including awareness of the potential for fragmentation of the angiocatheter during its removal over the in situ guidewire. Prompt recognition and appropriate management included leaving the guidewire in place (to stabilize the distal fragmented segment) and promptly consulting vascular surgery for removal before potential vascular embolization of the angiocatheter fragment. We further recommend that all components of the insertion kit be inspected before and after patient use.

Insufficienza respiratoria da versamento pleurico in un neonato con catetere venoso centrale

Peripherally Inserted Central Venous Catheter (PICC) insertion is a common procedure performed in most neonatal units. Even though this is a well-defined procedure for indications and risks, complications have been reported in literature. The paper reports a case of pleural effusion in a preterm newborn (31 weeks of gestation) as complication after PICC placement. A 7-day-old female infant with total parenteral nutrition via a PICC had an acute clinical deterioration requiring intubation and mechanical ventilation. Lung ultrasound revealed right pleural effusion, which was later confirmed by chest radiography. The PICC was promptly removed and thoracentesis performed, with a quick improvement of the respiratory conditions of the newborn.

Direct costs of rescue procedures to manage vascular access complications in conventional hemodialysis.

To measure the average direct cost of procedures performed by health professionals, in a Dialysis Center, for the management of complications of vascular access for hemodialysis. Quantitative, exploratory-descriptive case study type research. The average direct cost was calculated by multiplying the time spent by health professionals by the unit cost of direct labor, adding this to the input costs (materials/ medicines/solutions). The following average direct costs were obtained: US$0.72, US$2.00 and US$1.41 for "administration of easy-to-dilute, difficult-to-dilute, and undiluted antibiotics", respectively; $2.61 for "central venous catheter dressing with topical antibiotic"; $48.05 for "alteplase infusion"; US$183.68 for "insertion of central venous catheter for hemodialysis"; and $1.31 for "arteriovenous fistula puncture". Material and drug costs significantly contributed to the composition of the average total direct cost of most procedures.

Insertion of central venous catheters in children undergoing bone marrow transplantation: is there a platelet level for a safe procedure?

BackgroundBone marrow transplantation (BMT) is a therapeutic procedure for the management of several hematological diseases and malignancies in pediatric population. Central venous catheters (CVCs) play a pivotal role during the process of BMT. The aim of this study was to compare the complications of CVCs placements in children undergoing BMT with platelet levels above and below 50,000/μL and also to detect if there is a platelet count for a safe insertion. This prospective study included all children who had placements of tunneled CVCs during BMT at our hospital between March 2017 and March 2020. Procedures were divided into two groups accordingly to preoperative platelet counts (above and below 50,000/μL). Data were compared between both groups regarding postoperative complications including bleeding or catheter-related blood stream infections (CRBSIs).ResultsForty-six CVC insertions were performed in 40 patients. There were 20 procedures below 50,000/μL (median 27,500; range 5000–42,000) inserted with perioperative platelet transfusions, and their postoperative levels were median 59,500/μL, range 18,000–88,000. Allogeneic BMT was adopted in 39 patients (97.5%). Beta thalassemia major was the commonest indication (21/40, 52.5%), followed by acute lymphocytic leukemia in six patients (15%). There were nine postoperative complications (bleeding n = 2 and CRBSIs n = 7) encountered in all placements. Four of them occurred in insertions below 50,000/μL (two bleeding complications that managed conservatively, and two CRBSIs). Post-procedural morbidities regarding bleeding or CRBSIs did not differ significantly between both groups (p value = 0.099 and 0.695, respectively).ConclusionsPostponement of CVC insertions in thrombocytopenic children due to the fear of potential complications seems unwarranted, as it has no significant impact on the morbidity. Placements of such catheters can be safe under cover of perioperative platelet transfusions irrespective of the preoperative platelet count.

The \u201cbranching external jugular vein\u201d: an unreported clinically significant anatomic variation

BackgroundThe reported overall success rate for central venous catheter (CVC) insertion into the external jugular vein (EJV) is less than other central veins. A contributing factor for this might be the well-documented anatomical variations of the EJV. However, there are no reports correlating these anatomical variations with successful CVC insertion. Our aim was to evaluate the EJV anatomical variations and their clinical relevance.ResultsAll CVCs inserted over the study period were prospectively recorded with emphasis on the times the EJV was accessed, operative difficulties and any anatomical variations with their influence on CVC insertion. Over 15 months, 36 CVCs were inserted, 17 (47%) into EJV. For EJV line insertions, age is 39 days–14 years, 9 into right EJV. Operative difficulty was encountered in 4 patients (24%) where the catheter was inserted into EJV but failed to thread into a satisfactory position. In all 4 patients, further dissection revealed EJV branching into a bigger anterior branch which follows the course of main EJV yet not leading to the right atrium (RA) and a smaller posterior branch leading to RA. Regarding the 4 cases of “the branching EJV”, age is 2–14 years, 3 males:1 female and 3 left:1 right EJV. The overall success rate for CVC insertion through the EJV in this study was 100% including the 4 cases with “the branching EJV”.ConclusionsThis is the first report describing “the branching EJV” and its clinical relevance to CVC insertion.

Perioperative Echocardiography to Confirm Correct Central Venous Catheter Placement: A Case Report

Central venous catheterization is widely regarded as a safe procedure by anesthesiologists and intensivists, but insertion complications and catheter malposition remain challenges for the clinicians performing central venous catheter (CVC) insertion. We report a case in which a right internal jugular CVC was inserted under ultrasound guidance and was found to be malpositioned after sternotomy into an anomalous posterior thymic vein. Therefore, we recommend confirming the correct position of CVC with transesophageal echocardiography if such is indicated for the perioperative period and emphasize the importance of a correct J-tip of the guidewire when placing a CVC.

MONITORING OF PERIPHERAL VENOUS CATHETERIZATION AT THE SURGICAL HOSPITAL

Introduction. Peripheral venous catheters are widely used in medical practice to provide continuous venous access for therapeutic and diagnostic purposes. Peripheral vascular catheterization can be accompanied by infectious complications, including catheter-related bloodstream infections. An effective system of epidemiological surveillance and infection control of catheter-related bloodstream infections has not been developed at the state level in Ukraine; there is no proper monitoring for administration site and no registration of complications associated with the vascular catheterization. The purpose of this work was to assess the validity and propriety of the use of peripheral venous catheters in patients who receive inpatient treatment. Materials and methods: Between October 2019 and April 2020, 93 adult patients who were peripheral venous catheterized in a surgical hospital in Kharkiv were included in a prospective epidemiological study. The author's observation card was used for data collection for each patient daily. The catheter site was observed daily, and the following symptoms were entered into the card: flushed skin, swelling, discharge, and pain at the administration site at rest and on palpation. Interpretation of symptoms was conducted using the visual infusion phlebitis scale by A. Jackson. Statistical processing of data was carried out using descriptive statistics methods. To identify the relationship between the nominative values, Pearson's criterion χ2 was determined with P &lt; 0.01. Research results: 51 women (54.8%) and 42 men (45.2%) aged 18 to 84 were enrolled. In total, patients spent 619 bed-days in the hospital, of which the proportion of days with vascular catheters equaled 90.8% (n = 562). The main indication for the catheterization procedure was multicomponent therapy or the use of incompatible medications (98.9% / n = 92). In total, 148 peripheral venous catheters were inserted in these patients. The number of vascular catheters per patient ranged 1 to 3. According to the data of daily monitoring of the administration site, the signs of inflammation were observed in 65.5% of cases (n = 97). The incidence of signs of inflammation at the administration site with the first catheterization was significantly higher (χ2 = 25.2804; p &lt; 0.00001) than that with the second or third catheterization. The signs of local inflammation, which were more common in patients with vascular catheters, included flushed skin in the area of the catheter site (65.5% / n = 97), complaints of pain on palpation in the area of the catheter site (60.8% / n = 90) and swelling in the area of the catheter site (57.4% / n = 85). It was found that for more than half of the cases (55.4% / n = 82), the patients had symptoms of middle-stage phlebitis. It was also revealed that the most common reason for the removal of a peripheral venous catheter (n = 148) in the studied hospital were signs of local inflammation at the catheter site (61.5% / n = 91). However, in 16.9% of cases (n = 25), the occurrence of at least two signs of local inflammation at the catheter site, which indicated the initial stage of phlebitis and required to rearrange the catheter, was not the reason for immediate catheter removal. Conclusions: Health care workers make mistakes when working with peripheral venous catheters; in particular, there is no timely replacement of vascular catheters in the event of signs of infusion phlebitis. To reduce the risk of infectious complications of vascular catheterization at a health facility, the indications for insertion and removal of peripheral venous catheters and central venous catheters should be clearly defined, and standard operating procedures for ensuring vascular access and algorithms for managing patients with vascular catheters should be developed and implemented.

Lipid emulsion, but not propofol, induces skeletal muscle damage and lipid peroxidation

PurposeProlonged propofol infusion induces skeletal muscle damage. However, it is well known that the lipid emulsion that is the solvent of propofol causes various types of tissue damage via lipid peroxidation, and that propofol, conversely, has an anti-lipid peroxidative effect. The purpose of this study was to determine whether propofol or the lipid emulsion is the cause of muscle damage following prolonged administration.MethodsRats were divided into four groups: NI group (no intervention), Cath group (venous catheter insertion only), Prop group (1% propofol (Maruishi) intravenous infusion at 10 mg/kg/h), and Lipid group (10% Lipofundin® intravenous infusion at 100 mg/kg/h) (n = 10, each group). 1% Propofol (Maruishi) or Lipofundin was infused at 1 mL/kg/h for 72 h. The solvent of 1% propofol (Maruishi) is a 10% lipid emulsion. Lipofundin consists of 50% long-chain triacylglycerols and 50% medium-chain triacylglycerols, similar to the propofol solvent. Plasma concentrations of creatine kinase and myoglobin, superoxide production level, and 4-hydroxynonenal and malondialdehyde expression in the gastrocnemius muscle were evaluated 72 h after the interventions.ResultsPlasma concentrations of creatine kinase and myoglobin in the Lipid group were significantly higher than those in the other three groups. The superoxide production level, and 4-hydroxynonenal and malondialdehyde expression in the Lipid group were also significantly higher than in the other three groups.ConclusionLipofundin induces skeletal muscle damage via lipid peroxidation, and 1% propofol (Maruishi) conversely suppresses the muscle damage via antioxidant effects.
