Peripheral Access Options

Incidence of Midline Catheter Complications Among Hospitalized Patients

The use of midline catheters has increased to reduce excessive use of central venous access devices, and additional data on midline catheter complications are needed. This study aimed to describe midline catheter complications among hospitalized patients. This retrospective study included a random sample of 300 hospitalized patients with a midline catheter insertion in 2019. The primary outcome was a composite end point of 8 complications: occlusion, bleeding at insertion site, infiltration/extravasation, catheter-related thrombosis, accidental removal, phlebitis, hematoma, and catheter-related infection. Midline catheter failure was defined as removal prior to the end of therapy due to complications. Among 300 midline catheters, the incidence of the composite end point of 1 or more midline complications was 38% (95% confidence interval, 33%-44%). Complications included occlusion (17.0%), bleeding at insertion site (12.0%), infiltration/extravasation (10.0%), catheter-related thrombosis (4.0%), accidental removal (3.0%), phlebitis (0.3%), hematoma (0.3%), and catheter-related infection (0.3%). Midline catheter failure occurred in 16% of midline catheters (n = 48) due to infiltration/extravasation (n = 27), accidental removal (n = 10), catheter-related thrombosis (n = 9), occlusion (n = 4), and catheter-related infection (n = 1). Three catheters had 2 types of failure. The most common complications of occlusion and bleeding rarely resulted in midline catheter failure. The most common causes of midline catheter failure were infiltration/extravasation, accidental removal, and catheter-related thrombosis.

Instalação, manutenção e manuseio de cateteres venosos centrais de inserção periférica em pacientes submetidos a tratamento quimioterápico

Considerando que os cateteres venosos centrais de inserção periférica representam hoje uma nova opção para acesso venoso central utilizada por enfermeiros capacitados, este estudo teve como objetivo avaliar os cateteres instalados quanto ao seu tempo de permanência, determinar sua eficácia no tratamento com citostáticos, identificar possíveis problemas na sua instalação e manipulação e sugerir normas técnicas adequadas para a utilização destes dispositivos em pacientes do Instituto Nacional do Câncer (INCA)/Hospital do Câncer. Foram instalados 40 cateteres da marca L-Cath® em pacientes matriculados no serviço de Oncologia Clínica. Os dados relativos ao tempo de permanência dos dispositivos foram analisados utilizando valor mediano e os demais resultados foram analisados de forma descritiva. As complicações observadas e que acarretaram a retirada do cateter foram: exteriorização do cateter por ineficiência do curativo e adesivo; obstrução do cateter; flebite do acesso escolhido; dermatite de contato pela cola dos adesivos e curativos; perfuração do cateter por manipulação inadequada e mudança de conduta clínica. O tempo de permanência dos cateteres venosos centrais de inserção periférica variou de 1 a 169 dias. As normas técnicas adequadas para implantação, manutenção e manuseio destes cateteres para utilização em pacientes do INCA/Hospital do Câncer foram estabelecidas a partir deste estudo.

Safe central venous catheters for esophageal cancer treatment

 Introduction : Central venous catheter (CVC) use is essential for treating esophageal cancer. Peripherally inserted central catheters (PICC) are commonly used recently for improved patient comfort and safety. We compared centrally inserted central catheters (CICC) and PICC insertions and examined their safety. Methods : We retrospectively investigated complications at the catheter insertion and post-insertion for 199 patients' esophageal cancer treatment (CICC : 45, PICC : 154) from 2013 to 2018. In addition, we summarized the results of catheter tip culture. Results : No serious complications occurred at the catheter insertion in either group. The rate of complications at catheter insertion was 5.8% for PICC and 6.7% for CICC patients. Post-insertion complications were observed in 6.5% and 11.1% of patients with PICC and CICC, respectively, and this difference was not significant. The incidence of catheter-related blood stream infection (CRBSI) was significantly lower in PICC than CICC patients (0.3 vs. 1.8 / 1,000 catheter-days ; p = 0.029). Catheter-related thrombosis was observed in PICC : 0.5 and CICC : 0.6, and occlusion due to blood flow reversal was observed in PICC : 0.5 and CICC : 0.6. Conclusion : PICCs are safer and more effective than CICCs for the treatment of esophageal cancer, and reduce the incidence of CRBSI. We hope to standardize the insertion procedures, conventionalize techniques, and establish training systems. J. Med. Invest. 67 : 298-303, August, 2020.

The Practice and Complications of Midline Catheters: A Systematic Review

OBJECTIVE

Midline catheters are considered "midway" regarding vascular access. The objective of this systematic review was to explore the current practice, dwell time, and complication rates of midline catheters.

DESIGN

Systematic review.

SETTING

Search on four databases, PubMed, CINAHL, Scopus, and Embase, were conducted for English language articles published after the year 2000.

MEASUREMENTS AND MAIN RESULTS

A total of 987 articles were identified, of which 31 manuscripts met the inclusion criteria and were selected for review. Quality assurance was performed based on the Newcastle-Ottawa score. Average dwell time and complication rates were calculated for studies involving adult patients and adjusted for sample size. This analysis included data from the placement of 18,972 midline catheters across five countries. Aside from two randomized control trials, most of the studies analyzed were cohort studies. One pediatric and two neonatal studies were included. The average dwell time was 16.3 days (n = 4,412). The adjusted mean infection rate was 0.28/1,000 catheter days, with 64% of studies not reporting any infection with midline catheter. The failure rate of midline catheters was 12.5%. Adjusted average rates of other significant complications included the following: deep vein thrombosis (4.1%), dislodgement (5.0%), occlusion (3.8%), phlebitis (3.4%), and infiltration (1.9%).

CONCLUSIONS

The dwell times and failure rates of midline catheters compare favorably against published data on other types of catheters. Their infection rates are also lower than the reported rates of central venous catheters; however, they have a higher rate of mechanical complications. Active surveillance of infections due to midline catheters is recommended. More data are needed from pediatric and neonatal populations.

Investigation of the role of infusate properties related to midline catheter failure in an ovine model

PURPOSE

Infusate osmolarity, pH, and cytotoxicity were investigated as risk factors for midline catheter failure.

METHODS

An experimental, randomized, controlled, blinded trial was conducted using an ovine model. Two 10-cm, 18-gauge single-lumen midline catheters were inserted into the cephalic veins of sheep. The animals were divided into 6 study arms and were administered solutions of vancomycin 4 mg/mL (a low-cytotoxicity infusate) or 10 mg/mL (a high-cytotoxicity infusate), doxycycline 1 mg/mL (an acidic infusate), or acyclovir 3.5 mg/mL (an alkaline infusate) and 0.9% sodium chloride injection; or 1 of 2 premixed Clinimix (amino acids in dextrose; Baxter International) products with respective osmolarities of 675 mOsm/L (a low-osmolarity infusate) and 930 mOsm/L (a mid-osmolarity infusate). Contralateral legs were infused with 0.9% sodium chloride injection for control purposes. Catheter failure was evaluated by assessment of adverse clinical symptoms (swelling, pain, leakage, and occlusion). A quantitative vessel injury score (VIS) was calculated by grading 4 histopathological features: inflammation, mural thrombus, necrosis, and perivascular reaction.

RESULTS

Among 20 sheep included in the study, the overall catheter failure rate was 95% for test catheters (median time to failure, 7.5 days; range, 3-14 days), while 60% of the control catheters failed before or concurrently (median time to failure, 7 days; range, 4.5-14 days). Four of the 6 study arms (all but the Clinimix 675-mOsm/L and acyclovir 3.5-mg/mL arms) demonstrated an increase in mean VIS of ≥77% in test vs control legs (P ≤ 0.034). Both pain and swelling occurred at higher rates in test vs control legs: 65% vs 10% and 70% vs 50%, respectively. The mean difference in rates of occlusive pericatheter mural thrombus between the test and control arms was statistically significant for the vancomycin 10-mg/mL (P = 0.0476), Clinimix 930-mOsm/L (P = 0.0406), and doxycycline 1-mg/mL (P = 0.032) arms.

CONCLUSION

Administration of infusates of varied pH, osmolarity, and cytotoxicity via midline catheter resulted in severe vascular injury and premature catheter failure; therefore, the tested infusates should not be infused via midline catheters.

The “Arm-to-Chest Tunneling” technique: A modified technique for arm placement of implantable ports or central catheters

Purpose:

Central venous catheters or “venous access devices” include totally implantable venous access devices or “ports,” peripherally inserted central catheters, and tunneled lines. Venous access devices are now the standard of care in patients requiring long-term intravenous drug administration. Arm venous access device placement is a valuable option for vascular access yet often complicated or rendered practically impossible by the condition and size of peripheral veins. We describe a modification of the arm venous access device implantation technique that we use in our department in order to offer this option to our patients, regardless of their peripheral veins condition.

Methods:

After ultrasound guided venous access of a suitable neck vein, we create a port pouch—in case of a totally implantable vascular access device—or a skin nick—in case of a venous access device—in the inner aspect of the mid-arm. Using a straight metal tunneler, we tunnel the line from the neck to the arm in two stages, externalizing and re-inserting the line into a skin nick made on the deltopectoral groove. We call this technique “Arm-to-Chest Tunneling” and use it to place venous access devices in the arm using a neck venous access.

Results:

The Arm-to-Chest Tunneling technique allows us to use larger arm venous access device catheters irrespective of the arm veins condition. Thus, this technique has the advantages of arm venous access device placement, with the added benefit of saving the arm veins.

Conclusion:

The “Arm-to-Chest Tunneling” method offers the alternative to place a venous access device in a more discreet site in the arm, even in cases in which arm veins are inadequate.

Peripherally inserted central catheters: dependency of radiation exposure from puncture site and level of training

Background Several interventional procedures show a dependency on fluoroscopy times (FT) and level of training. Furthermore, FT and dose area products (DAP) vary depending on access site and target vessel for chest port implantations, but not for other thoracic interventions such as percutaneous coronary interventions. Purpose To evaluate the influence of the combination of venous access site and level of training on FTs and DAPs during peripherally inserted central catheters (PICC) implantations in a large cohort of patients. Material and Methods In this retrospective study, PICC implantations of 681 consecutive patients (385 women, 296 men; mean age = 55.0 ± 16.7 years) were analyzed. Two groups of junior (< 50 interventions) and senior (≥ 50 implantations) radiologists were investigated in respect to FT and DAP during PICC placement procedures. Statistical analysis included the Mann-Whitney U test and the Kruskal-Wallis test. P values < 0.05 were considered significant. Results Senior radiologists required significantly less FT (senior = 0.43 s, junior = 0.53 s, P = 0.041), but there was no significant difference in DAPs (senior = 56.3 µGy*m², junior = 60.6 µGy*m², P = 0.151). PICC implantations through the left side resulted in a significant reduction of the median FT by 60.9% (left = 0.45 s, right = 1.15 s, P = 0.010). Conclusion Due to considerable dose reduction, the left-sided puncture, especially via the basilic and brachial veins, performed by well-trained interventional radiologists seem to be the preferable approach for PICCs.

ACR Appropriateness Criteria® Radiologic Management of Central Venous Access

Obtaining central venous access is one of the most commonly performed procedures in hospital settings. Multiple devices such as peripherally inserted central venous catheters, tunneled central venous catheters (eg, Hohn catheter, Hickman catheter, C. R. Bard, Inc, Salt Lake City UT), and implantable ports are available for this purpose. The device selected for central venous access depends on the clinical indication, duration of the treatment, and associated comorbidities. It is important for health care providers to familiarize themselves with the types of central venous catheters available, including information about their indications, contraindications, and potential complications, especially the management of catheters in the setting of catheter-related bloodstream infections. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Experience of Peripherally Inserted Central Venous Catheter in Patients with Hematologic Diseases

Objective Although use of the peripherally inserted central venous catheter (PICC) has become increasingly common, there are few reports of PICCs used for patients with hematologic diseases. In this study, we analyzed the safety of PICC placement in patients with hematologic diseases where PICCs had been placed to perform blood collection, blood transfusion, drug administration, and hematopoietic stem cell transplantation. Methods This study included 142 PICCs placed in 95 patients managed at our department from November 2013 to December 2015. The PICCs used were the Groshong^® Catheter (NXT single-lumen; BARD Inc.). Results A total of 95 patients underwent the placement of 142 PICCs. The mean patient age was 65.5 years. The total duration of catheterization was 8,089 days, with a mean duration of 57.0 days. Chemotherapy was administered through 107 catheters. Stem cells were injected through 12 catheters. Although a fever was observed in association with 103 catheters, it was generally controlled by antimicrobial therapy. There were 18 catheter-related bloodstream infection (CRBSI) cases, an incidence equivalent to 2.1 cases per 1,000 catheter-days. Conclusion The present study demonstrated a low CRBSI incidence rate and found no evidence of serious complications with PICC placement. PICCs can be used for blood collection, blood transfusion, drug administration, and hematopoietic stem cell transplantation without problems. Thus, PICC placement appears to be a safe procedure for patients with hematologic diseases. Safe catheters are therefore urgently needed for these patients. We expect that PICCs will be widely adopted in Japan in the near future.

Comparison of Inversion ("flipping") Rates Among Different Port Designs: A Single-Center Experience

PURPOSE

To compare incidence of port inversion among different types of implantable venous access devices.

MATERIALS AND METHODS

Records of patients who underwent imaging-guided subcutaneous port placement without port fixation between July 2001 and April 2015 were reviewed with use of a quality assurance database. 1930 patients with complete follow-up (death or explant) were included in the study. Collected data included date and indication for port placement, port type, venous access site, immediate and long-term complications, indication for removal, and total number of catheter days. BMI of patients with inverted ports was also calculated.

RESULTS

Port inversion within the pocket was observed in 18 patients (0.9%) including 7/82 (9%) of Dignity ports, 4/126 (3%) of Vaxcel plastic arm ports, 3/142 (2%) of Smartports, 2/100 (2%) of Powerports, 1/14 (7%) of Vaccess ports, and 1/1421 (0.07%) of Vortex LP ports. Among these designs, the inversion rate was significantly lower in Vortex LP ports (0.1%) (P < 0.05). There was a trend toward higher inversion rate of Dignity ports, which have a rectangular design with a relatively narrow base. Mean dwell in inverted ports was 114 days (7-580).

CONCLUSION

The incidence of port inversion without suture fixation of the port base to the pocket is extremely low. The present study shows differences in inversion incidence based on port design.

LEVEL OF EVIDENCE

Case Series, Level IV.

Intermittently delivered IV medication and pH: reevaluating the evidence

The Infusion Nurses Society's Infusion Nursing Standards of Practice has treated pH as a critical factor in the decision-making process for vascular access device selection, stating that an infusate with a pH less than 5 or greater than 9 is not appropriate for short peripheral or midline catheters. Because of the Standards, drug pH is not an uncommon factor driving the decision for central vascular access. In this era of commitment to evidence-based practice, the pH recommendation requires reevaluation and a critical review of the research leading to infusate pH as a decisional factor. In this narrative literature review, historical and current research was appraised and synthesized for pH of intermittently delivered intravenous medications and the development of infusion thrombophlebitis. On the basis of this review, the authors conclude and assert that pH alone is not an evidence-based indication for central line placement.

Current situation regarding central venous port implantation procedures and complications: a questionnaire-based survey of 11,693 implantations in Japan

BACKGROUND

We conducted a nationwide questionnaire-based survey to understand the current situation regarding central venous port implantation in order to identify the ideal procedure.

METHODS

Questionnaire sheets concerning the number of implantation procedures and the incidence of complications for all procedures completed in 2012 were sent to 397 nationwide designated cancer care hospitals in Japan in June 2013. Venipuncture sites were categorized as chest, neck, upper arm, forearm, and others. Methods were categorized as landmark, cut-down, ultrasound-mark, real-time ultrasound guided, venography, and other groups.

RESULTS

We received 374 responses (11,693 procedures) from 153 centers (38.5 %). The overall complication rates were 7.4 % for the chest (598/8,097 cases); 6.8 % for the neck (157/2325); 5.2 % for the upper arm (54/1,033); 7.3 % for the forearm (9/124); and 6.1 % for the other groups (7/114). Compared to the chest group, only the upper arm group showed a significantly lower incidence of complications (P = 0.010), and multivariate logistic regression (odds ratio 0.69; 95 % confidence interval 0.51-0.91; P = 0.008) also showed similar findings. Real-time ultrasound-guided puncture was most commonly used in the upper arm group (83.8 %), followed by the neck (69.8 %), forearm (53.2 %), chest (41.8 %), and other groups (34.2 %).

CONCLUSION

Upper arm venipuncture with ultrasound guidance seems the most promising technique to prevent complications of central venous port implantation.

The “L-shaped Tunneling Technique”: A Modified Technique Facilitating a more Discreet Implantable Port Positioning

Purpose

Venous port catheters, also known as “totally implantable venous access devices” (TIVADs), are now the standard of care in patients requiring long-term intermittent intravenous drug administration. We describe a modification of the implantation technique that we use in our department in order to improve the cosmetic result of a TIVAD.

Methods

After ultrasound-guided venous access in the internal jugular vein (IJV) or another appropriate vein has been obtained, we create a port pocket in the deltopectoral groove, in the upper-lateral chest wall, in a “far-lateral-oblique” orientation, respecting the individual patient's relaxed skin tension lines. Then we create a subcutaneous tunnel using a straight metal tunneler in two steps: first tunneling cranially and perpendicular to the port incision for a small distance, and then, after turning the tunneler at a right angle continuing in a straight line until we exit at the venous access site.

Results

This configuration not only prevents catheter kinking, to ensure uninhibited flow, but also allows us to place the port pocket in a more discreet position, in order to offer a better cosmetic result to our patients.

Conclusions

Adoption of a “far-lateral-oblique” port implantation site along with the “L-shaped tunneling technique” will offer doctors who are implanting TIVADs a useful alternative for a better cosmetic result.

Cost and Morbidity Analysis of Chest Port Insertion: Interventional Radiology Suite Versus Operating Room

PURPOSE

To compare complications and cost, from a hospital perspective, of chest port insertions performed in an interventional radiology (IR) suite versus in surgery in an operating room (OR).

METHODS

This study was approved by an institutional review board and is HIPAA compliant. Medical records were retrospectively searched on consecutive chest port placement procedures, in the IR suite and the OR, between October 22, 2010 and February 26, 2013, to determine patients' demographic information and chest port-related complications and/or infections. A total of 478 charts were reviewed (age range: 21-85 years; 309 women, 169 men). Univariate and bivariate analyses were performed to identify risk factors associated with an increased complication rate. Cost data on 149 consecutive Medicare outpatients (100 treated in the IR suite; 49 treated in the OR) who had isolated chest port insertions between March 2012 and February 2013 were obtained for both the operative services and pharmacy. Nonparametric tests for heterogeneity were performed using the Kruskal-Wallis method.

RESULTS

Early complications occurred in 9.2% (22 of 239) of the IR patients versus 13.4% (32 of 239) of the OR patients. Of the 478 implanted chest ports, 9 placed in IR and 18 placed in surgery required early removal. Infections from the ports placed in IR versus the OR were 0.25 versus 0.18 infections per 1000 catheters, respectively. Overall mean costs for chest port insertion were significantly higher in the OR, for both room and pharmacy costs (P < .0001). Overall average cost to place chest ports in an OR setting was almost twice that of placement in the IR suite.

CONCLUSIONS

Hospital costs to place a chest port were significantly lower in the IR suite than in the OR, whereas radiology and surgery patients did not show a significantly different rate of complications and/or infections.

Peripherally Inserted Central Venous Catheter–Associated Bloodstream Infections in Hospitalized Adult Patients

Background.

Limited data on the risk of peripherally inserted central venous catheter-associated bloodstream infections (PICC BSIs) in hospitalized patients are available. In 2007, dedicated intravenous therapy nurses were no longer available to place difficult peripheral intravenous catheters or provide PICC care Barnes-Jewish Hospital.

Objectives.

To determine the hospital-wide incidence of PICC BSIs and to assess the effect of discontinuing intravenous therapy service on PICC use and PICC BSI rates.

Setting.

A 1,252-bed tertiary care teaching hospital.

Methods.

A 31-month retrospective cohort study was performed. PICC BSIs were defined using National Healthcare Safety Network criteria.

Results.

In total, 163 PICC BSIs were identified (3.13 BSIs per 1,000 catheter-days). PICC use was higher in intensive care units (ICUs) than non-ICU areas (PICC utilization ratio, 0.109 vs 0.059 catheter-days per patient-day for ICU vs non-ICU; rate ratio [RR], 1.84 [95% confidence interval {CI}, 1.78-1.91]). PICC BSI rates were higher in ICUs (4.79 vs 2.79 episodes per 1,000 catheter-days; RR, 1.7 [95% CI, 1.10-2.61]). PICC use increased hospital-wide after the intravenous therapy service was discontinued (0.049 vs 0.097 catheter-days per patient-day; P = .01), but PICC BSI rates did not change (2.68 vs 3.63 episodes per 1,000 catheter-days; P = .06). Of PICC BSIs, 73% occurred in non-ICU patients.

Conclusions.

PICC use and PICC BSI rates were higher in ICUs; however, most of the PICC BSIs occurred in non-ICU areas. Reduction in intravenous therapy services was associated with increased PICC use across the hospital, but PICC BSI rates did not increase.

Guideline for Prevention of Intravascular-Device–Related Infections

The “Guideline for Prevention of Intravascular Device-Related Infections” is designed to reduce the incidence of intravascular device-related infections by providing an over view of the evidence for recommendations considered prudent by consensus of Hospital Infection Control Practices Advisor y Committee (HICPAC) members. This two-part document updates and replaces the previously published Centers for Disease Control's (CDC) Guideline for Intravascular Infections (Am J Infect Control1983;11:183-199). Part I, “Intravascular Device-Related Infections: An Over view” discusses many of the issues and controversies in intravascular-device use and maintenance. These issues include definitions and diagnosis of catheter-related infection, appropriate barrier precautions during catheter insertion, inter vals for replacement of catheters, intravenous (IV) fluids and administration sets, catheter-site care, the role of specialized IV personnel, and the use of prophylactic antimi-crobials, flush solutions, and anticoagulants. Part II, “Recommendations for Prevention of Intravascular Device-Related Infections” provides consensus recommendations of the HICPAC for the prevention and control of intravascular device-related infections. A working draft of this document also was reviewed by experts in hospital infection control, internal medicine, pediatrics, and intravenous therapy. However, all recommendations contained in the guideline may not reflect the opinion of all reviewers.

Guidelines for the Prevention of Intravascular Catheter–Related Infections

Background:

Although many catheter-related blood-stream infections (CRBSIs) are preventable, measures to reduce these infections are not uniformly implemented.

Objective:

To update an existing evidenced-based guideline that promotes strategies to prevent CRBSIs.

Data Sources:

The MEDLINE database, conference proceedings, and bibliographies of review articles and book chapters were searched for relevant articles.

Studies Included:

Laboratory-based studies, controlled clinical trials, prospective interventional trials, and epidemiologic investigations.

Outcome Measures:

Reduction in CRBSI, catheter colonization, or catheter-related infection.

Synthesis:

The recommended preventive strategies with the strongest supportive evidence are education and training of healthcare providers who insert and maintain catheters; maximal sterile barrier precautions during central venous catheter insertion; use of a 2% chlorhexidine preparation for skin antisepsis; no routine replacement of central venous catheters for prevention of infection; and use of antiseptic/antibiotic-impregnated short-term central venous catheters if the rate of infection is high despite adherence to other strategies (ie, education and training, maximal sterile barrier precautions, and 2% chlorhexidine for skin antisepsis).

Conclusion:

Successful implementation of these evidence-based interventions can reduce the risk for serious catheter-related infection.

Management of peripherally inserted central catheters (PICC) in pediatric heart failure patients receiving continuous inotropic support

The study aim was to evaluate present practice of maintaining PICC line patency in pediatric heart failure patients receiving continuous inotropes by comparing one cohort receiving low dose continuous heparin with one receiving no heparin. A case control retrospective chart review compared the two cohorts on duration of patency (measured in days) and need for thrombolytic agents. Median duration of patency for the heparin group was 24 days versus 16 days for the no heparin group (p=0.07). Use of thrombolytic agents was 28% in the heparin group compared to 50% in the no heparin group (p=0.08). Although not statistically significant, findings were clinically significant and supportive of current practice.

Upper arm central venous port implantation: a 6-year single institutional retrospective analysis and pictorial essay of procedures for insertion

Background

The requirement of central venous (CV) port implantation is increasing with the increase in the number of cancer patients and advancement in chemotherapy. In our division, medical oncologists have implanted all CV ports to save time and consultation costs to other departments. Recently, upper arm implantation has become the first choice as a safe and comfortable method in our unit. Here we report our experience and discuss the procedure and its potential advantages.

Methods

All CV port implantations (n = 599) performed in our unit from January 2006 to December 2011 were analyzed. Procedural success and complication rates between subclavian and upper arm groups were compared.

Results

Both groups had similar patient characteristics. Upper arm CV port and subclavian implantations were equivalently successful and safe. Although we only retrospectively analyzed data from a single center, the upper arm group had a significantly lower overall postprocedural complication rate than the subclavian group. No pneumothorax risk, less risk of arterial puncture by ultrasound, feasibility of stopping potential arterial bleeding, and prevention of accidental arterial cannulation by targeting the characteristic solitary basilic vein were the identified advantages of upper arm CV port implantation. In addition to the aforementioned advantages, there is no risk of “pinch-off syndrome,” possibly less patient fear of manipulation, no scars on the neck and chest, easier accessibility, and compatibility with the “peripherally inserted central catheter” technique.

Conclusions

Upper arm implantation may benefit clinicians and patients with respect to safety and comfort. We also introduce our methods for upper arm CV port implantation with the videos.

epic3: national evidence-based guidelines for preventing healthcare-associated infections in NHS hospitals in England

National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were originally commissioned by the Department of Health and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were first published in January 2001(1) and updated in 2007.(2) A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective for the prevention of HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. The Department of Health commissioned a review of new evidence and we have updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the epic2 guidelines published in 2007 remain robust, relevant and appropriate, but some guideline recommendations required adjustments to enhance clarity and a number of new recommendations were required. These have been clearly identified in the text. In addition, the synopses of evidence underpinning the guideline recommendations have been updated. These guidelines (epic3) provide comprehensive recommendations for preventing HCAI in hospital and other acute care settings based on the best currently available evidence. National evidence-based guidelines are broad principles of best practice that need to be integrated into local practice guidelines and audited to reduce variation in practice and maintain patient safety. Clinically effective infection prevention and control practice is an essential feature of patient protection. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of health care in NHS hospitals in England can be minimised.

[The PICC line, a new approach for venous access]

Peripheral Inserted Central Catheter (PICC) line is a peripherally inserted central catheter. This implantable medical device is placed into a peripheral vein of the arm in order to obtain an intravenous central access. This device can find its use in various applications like intravenous delivery of parenteral nutrition, anticancer agents and antibiotics, as well as for blood sampling. PICC line is not widely used in medical practice because it remains largely unknown. The aim of this review is thus to introduce PICC line to the medical and scientific community. First, we will approach its insertion and maintenance of the dressing. We will then detail the benefits and drawbacks associated with its use, and finally discuss its position with regards to the other central venous access available.

Peripherally inserted central catheter bloodstream infection surveillance rates in an acute care setting in Saudi Arabia

BACKGROUND AND OBJECTIVE

Peripherally inserted central venous catheters (PICCs) are alternatives to short-term central venous catheters and provide intravenous access in the acute hospital setting. In this study, we describe the rate of PICC-associated bloodstream infections (BSI).

DESIGN AND SETTING

Prospective cohort study using data on PICC lines reviewed from January to December 2009.

METHODS

The infection control team was responsible for prospective BSI case findings. The infection rate was calculated per 1000 device-days.

RESULTS

During the study period, 92 PICC lines were inserted with a total of 3336 device-days of prospective surveillance. The most frequent reasons for the insertion of the PICC lines were chemotherapy (n=19, 20.7%), intravenous antimicrobial therapy (n=34, 37%), and for patients in the medical intensive care unit (ICU) (n=16, 17.4%). The overall BSI rate was 4.5/1000 PICC days. The PICC line-associated BSI rates for a specific indication were as follows: chemotherapy 6.6/1000 device-days, intravenous antimicrobial therapy 1.2/1000 device-days, medical ICU 7.3/1000 device-days, surgical ICU 4.6/1000 device-days, and total parental nutrition patients 2.4/1000 device-days (P<.001). The rates were not adjusted for patient severity of illness.

CONCLUSIONS

Our data suggest that underlying conditions and indications for the PICC line use may play an important role in the development of BSI.

An evaluation of peripherally inserted central venous catheters for children with cancer requiring long-term venous access

Long-term venous access is essential when treating malignant diseases. We reviewed our experience with peripherally inserted central venous catheters (PICC) in children suffering from various malignancies with regard to catheter life, reasons for removal, and complications. Ninety-three PICCs were inserted in 78 children. Median catheter life was 162 days (range 6-575 days) with a total of 16,266 catheter days. Seventy-five PICCs (80.6%) had been placed until the elective removal or patients' death, whereas 18 PICCs (19.4%) were removed due to PICC-related complications; a rate of 1.11 per 1,000 catheter days. Complications requiring removal of PICCs included infection (n = 12), occlusion (n = 3), dislodgement (n = 2), and phlebitis (n = 1) with rates of 0.74, 0.18, 0.12 and 0.06 per 1,000 catheter days, respectively. We conclude that PICC provides reliable long-term intravenous access in children suffering from malignancies.

Central venous catheters in neonates: from simple monolumen to port catheter

The use of central venous catheters (CVCs) represents an important step in the management of the surgical, onco-hematology and critically ill patients. CVCs in neonates, like in adult patients, are mainly used to infuse hyperosmolar solutions, to take blood samples and for hemodynamic monitoring. The need for CVCs is higher in neonates than in adults. Poor peripheral access and the high demand for IV access and blood samples are already valuable indications for a CVC.

Overview of enteral and parenteral feeding access techniques: principles and practice

The importance of adequate nutrition has long been established in the surgical patient population. Enteral nutrition provides the safest, most cost-effective approach with endoscopic and surgical options for permanent access. Parenteral nutrition should be reserved for patients in whom enteral nutrition is contradicted. This article summarizes the routes of access for both enteral and parenteral nutrition as well as the indications, procedural pearls, and complications associated with each approach.

Safety and effectiveness of central venous catheterization in patients with cancer: prospective observational study

This study investigated the safety and effectiveness of each type of central venous catheters (CVC) in patients with cancer. We prospectively enrolled patients with cancer who underwent catheterization involving a subclavian venous catheter (SVC), peripherally inserted central venous catheter (PICC), or chemo-port (CP) in our department. From March 2007 to March 2009, 116 patients underwent 179 episodes of catheterization. A SVC was inserted most frequently (46.4%). Fifty-four complications occurred (30.1%): infection in 23 cases, malpositioning or migration of the tip in 18 cases, thrombosis in eight cases, and bleeding in five cases. Malpositioning or migration of the tip occurred more frequently with a PICC (P<0.001); infection occurred more often with a tunneled catheter (P=0.028) and was observed more often in young patients (P=0.023). The catheter life span was longer for patients with solid cancer (P=0.002) than for those with hematologic cancer, with a CP (P<0.001) than a PICC or SVC, and for an indwelling catheter with image guidance (P=0.014) than a blind procedure. In conclusion, CP is an effective tool for long term use and the fixation of tip is important for the management of PICC.

Survey of the long-term use of peripherally inserted central venous catheters in children with cancer: experience in a developing country

Peripherally inserted central catheters (PICCs) have been used for many years in developed countries, but few studies have been focused on children with cancer in developing countries. In this study, we assessed the feasibility of PICCs and determined the rate of PICC-related complications in children with cancer. We prospectively followed all children with cancer over 3 years of age who received chemotherapy and PICC placement in our cancer center between June 2003 and May 2007. The date of last follow-up was January 31, 2008. A total of 119 PICCs were inserted into 116 patients during the 48-month period. PICCs were placed in 113 of 119 attempts, yielding an insertion rate of 95.0%. The 113 PICCs were in place for a total 26,721 catheter days (median time, 246 d; range, 8 to 455 d). The 113 PICCs had 53 overall complications, for a rate of 1.98/1000 catheter days. Twenty-one (18.6%) PICCs were removed because of complication with a rate of 0.79/1000 catheter days. The most common reason for PICC removal was breakage/leakage. An infection requiring PICC removal occurred in 4 patients. This study demonstrated relatively low complication rate and long duration for PICCs in children with cancer over 3 years of age in our hospital.

Peripherally inserted central venous catheters are a good option for prolonged venous access in children with cancer

BACKGROUND

A long term venous access device is essential in children with malignancies for the safe administration of medication and to avoid repeated painful venipunctures. The advantage of peripherally inserted central venous catheters (PICC) over conventional central venous catheter (CVC) is easy bedside insertion without need for general anesthesia and theatre time. The purpose of this study was to evaluate our experience with PICCs particularly with regard to catheter life, reason for removal and complications in children suffering from various malignancies.

PROCEDURE

A retrospective analysis of all PICCs inserted in children with cancer was done with regard to the demographic data, catheter life, reason for removal, and complications. The latter two were evaluated in association with patient age, catheter days, and year of insertion.

RESULTS

Of 127 catheters inserted in 127 children, median catheter life was 161 days with a total of 18,955 catheter days (for 124 patients, 3 lost to follow-up). Elective removal occurred in 63/101 (62.4%) PICCs and removal due to complications resulted in a complication rate of 2.41 per 1,000 catheter days. The common reasons for catheter removal were suspected infection, breakage/leakage, dislodgement, phlebitis, and occlusion with rates of 1.27, 0.57, 0.31, 0.06, and 0.06 per 1,000 catheter days, respectively.

CONCLUSION

We found PICC to be a convenient, cheap, safe, and reliable device for long term intravenous access in children with malignancies. This was possible with the help of dedicated catheter care nurses.

Central venous thrombosis in patients receiving long-term parenteral nutrition

Long-term parenteral nutrition (PN) is administered to patients who are unable to use their gastrointestinal tract to absorb sufficient nutrients and water to maintain their nutritional status. Patients receiving long-term parenteral nutrition are at risk of numerous complications including thrombosis of the central venous catheter used to provide nutrition. Central venous access is essential to the successful delivery of long-term PN. One of the strategies to lessen the frequency of this complication is anticoagulation therapy with warfarin. The effect of warfarin in preventing this complication may be modified by vitamin K intake. Individuals with gastrointestinal failure may receive vitamin K from a variety of sources. This review summarizes the role of warfarin in preventing central venous access thrombosis. It also summarizes potential sources of vitamin K intake in home parenteral nutrition patients, examines the evidence for recommendations regarding vitamin K intake, and considers the potential impact of increased vitamin K intake on home PN patients, particularly on the prevention of central venous thrombosis.

Survey of the use of peripherally inserted central venous catheters in neonates with critical congenital cardiac disease

Neonates with congenital cardiac disease are a special population. They are often critically ill, and need prolonged intravenous access. To date, no study has evaluated the efficacy and safety of peripherally inserted central venous catheters placed in this unique population. Our goal was to evaluate the use of such catheters in neonates with critical congenital cardiac disease, and to study features such as duration of use, reasons for removal of catheters, and complications. We inserted a total of 124 catheters in 115 neonates with critical congenital cardiac disease who were admitted to the Intensive Care Unit at Texas Children's Hospital from August 2002 to August 2004. The patients had a mean age of 10 days, and a mean weight of 3.1 kilograms. The peripherally inserted catheters were in place for a mean of 22.3 days. Therapy was completed in 76.6% patients at the time of removal of the catheter. The incidence of occlusion, dislodgement, and thrombus was 4.0%, 2.4%, and 1.6%, respectively. The infection rate was 3.6 per 1000 catheter-days, with a median onset on 37 days after placement. We conclude that central venous catheters, when inserted peripherally, provide reliable and safe access for prolonged intravenous therapy in neonates with critical congenital cardiac disease.

epic2: National evidence-based guidelines for preventing healthcare-associated infections in NHS hospitals in England

National evidence-based guidelines for preventing healthcare-associated infections (HCAI) in National Health Service (NHS) hospitals in England were commissioned by the Department of Health (DH) and developed during 1998-2000 by a nurse-led multi-professional team of researchers and specialist clinicians. Following extensive consultation, they were published in January 2001. These guidelines describe the precautions healthcare workers should take in three areas: standard principles for preventing HCAI, which include hospital environmental hygiene, hand hygiene, the use of personal protective equipment, and the safe use and disposal of sharps; preventing infections associated with the use of short-term indwelling urethral catheters; and preventing infections associated with central venous catheters. The evidence for these guidelines was identified by multiple systematic reviews of experimental and non-experimental research and expert opinion as reflected in systematically identified professional, national and international guidelines, which were formally assessed by a validated appraisal process. In 2003, we developed complementary national guidelines for preventing HCAI in primary and community care on behalf of the National Collaborating Centre for Nursing and Supportive Care (National Institute for Healthand Clinical Excellence). A cardinal feature of evidence-based guidelines is that they are subject to timely review in order that new research evidence and technological advances can be identified, appraised and, if shown to be effective in preventing HCAI, incorporated into amended guidelines. Periodically updating the evidence base and guideline recommendations is essential in order to maintain their validity and authority. Consequently, the DH commissioned a review of new evidence published following the last systematic reviews. We have now updated the evidence base for making infection prevention and control recommendations. A critical assessment of the updated evidence indicated that the original epic guidelines published in 2001 remain robust, relevant and appropriate but that adjustments need to be made to some guideline recommendations following a synopsis of the evidence underpinning the guidelines. These updated national guidelines (epic2) provide comprehensive recommendations for preventing HCAI in hospitals and other acute care settings based on the best currently available evidence. Because this is not always the best possible evidence, we have included a suggested agenda for further research in each section of the guidelines. National evidence-based guidelines are broad principles of best practice which need to be integrated into local practice guidelines. To monitor implementation, we have suggested key audit criteria for each section of recommendations. Clinically effective infection prevention and control practice is an essential feature of protecting patients. By incorporating these guidelines into routine daily clinical practice, patient safety can be enhanced and the risk of patients acquiring an infection during episodes of healthcare in NHS hospitals in England can be minimised.

Evidence-Based Practice in the Management of Vascular Access Devices for Home Parenteral Nutrition Therapy

Catheter-related bloodstream infection and catheter occlusion are potential significant complications of parenteral nutrition therapy. The increased incidence and associated morbidity, mortality, increased costs, and quality-of-life issues experienced with these adverse events necessitate specialized management of vascular access devices. The host coagulation response to biomaterials and the associated development of biofilm on vascular devices are complex phenomena. Multiple interventions are required to prevent access of bacteria to both intraluminal and extraluminal catheter surfaces, and the occurrence of catheter occlusion. The discovery of the biofilm form of microbial life and the associated recalcitrance of biofilm bacteria to antimicrobials has provided insight into the failure of current prevention, diagnostic, and treatment protocols. Critical interventions are presented correlating current evidence with new discoveries in pathogenesis.

Long-term use of peripherally inserted central venous catheters for cancer chemotherapy in children

BACKGROUND

Peripherally inserted central venous catheters (PICCs) have been increasingly used in pediatric patients. However, little is known about the incidence and risk of complications when using this device in children with cancer. The purposes of this study are to assess the feasibility of PICCs and to determine the risk factors for PICC-related complications in pediatric patients with various types of malignancies.

PATIENTS AND METHODS

We attempted to place PICCs in 53 patients with a median age of 5 years ranging from 2 months to 20 years. PICCs were used to administer fluid, parenteral nutrition, anticancer agents, antibiotics, and blood products and also for the through-line blood sampling. The duration of catheterization and the incidence of PICC-related complications requiring removal were retrospectively evaluated in association with the diagnosis, sex, age and body weight of the patients, size, insertion site and tip location of the catheters, type of treatment, and duration of leukopenia.

RESULTS

PICCs were successfully placed in 109 of 112 attempts (97.3%) in 53 patients, and they were followed for a total of 11,797 catheter days (median placement, 87 days; range, 3 to 512 days). Fifty five PICCs (50.5%) were removed as a result of PICC-related complications with a rate of 4.66 per 1,000 catheter days. The most common reasons for catheter removal were occlusion (n=18), breakage/leakage (15), and infection (10). More than 70% of such complications occurred more than 30 days after placement. The catheter tip location in the superior vena cava or the right atrium might decrease the risk of complications. Other parameters did not influence the incidence of complications.

CONCLUSIONS

PICCs were found to provide a reliable access for prolonged intravenous administration and blood sampling in children intensively treated for hematologic and solid malignancies, thus leading to a reduction of physical pain and psychological stress in such patients. However, the long-term placement of PICCs may also be related to an increased risk of complications.

Cost losses associated with the "PICC, stick, and run team" concept

Covenant Healthcare System is a 500-bed facility in Saginaw, Michigan. A peripherally inserted central catheter (PICC) program was instituted there in 1990 when it was St. Lukes Hospital. Over the course of 17 years, 30 nurses had been trained to place PICCs in their spare time. A "PICC, stick, and run team" was established in 1998 but was unsuccessful. After a merger with Saginaw General Hospital, Covenant Healthcare created two full-time vascular access specialty positions. This nursing-based PICC program with full-time staffing has revitalized vascular access at Covenant Healthcare System. Currently, PICCs are placed proactively at the beginning of hospital stays. Peripheral catheter restarts have been replaced with reliable PICC access sites. Delayed discharge for PICC insertion is no longer an issue.

Current practice in administration of parenteral nutrition: venous access

Today, there are many alternative feeding options for patients unable to eat and drink and nutrition support has become part of everyday clinical practice. Although feeding via the enteral route used to be considered optional, recent experts have re-examined the role of parenteral nutrition, and found it to be as beneficial. This article will review current practice surrounding parental nutrition, its indications and the associated complications. Successful feeding via the intravenous route relies on the selection of the appropriate intravenous access, optimum nursing care and close patient monitoring. The range of venous access options will be discussed and advantages and disadvantages identified.

Central venous catheters: choosing the most appropriate access route

Intravenous therapy and care is a complex and intricate area of practice, which is being subsumed into the core role of registered nurses. As more patients become recipients of a vascular access device (VAD), particularly those requiring intermediate to long-term central venous access, it is important to ensure that not only the device but also the most appropriate vein meets their clinical physiological and psychological needs. There is much research and literature on the insertion and care of central venous catheters (CVCs) as well as the detection and treatment of complications. However, apart from a few small studies comparing the performance of devices placed either in the subclavian or jugular veins, there is little to guide doctors or nurses as to which vein is preferable, if secondary complications are to be avoided. This article will describe a number of primary and secondary complications associated with both the subclavian and internal jugular veins and how these can be minimized by selecting the most appropriate vessel. The article concludes with the author's suggestions for correct patient assessment in order that the correct vein is utilized.

Guidelines for the prevention of intravascular catheter-related infections

BACKGROUND

Although many catheter-related bloodstream infections (CRBSIs) are preventable, measures to reduce these infections are not uniformly implemented.

OBJECTIVE

To update an existing evidenced-based guideline that promotes strategies to prevent CRBSIs.

DATA SOURCES

The MEDLINE database, conference proceedings, and bibliographies of review articles and book chapters were searched for relevant articles.

STUDIES INCLUDED

Laboratory-based studies, controlled clinical trials, prospective interventional trials, and epidemiologic investigations.

OUTCOME MEASURES

Reduction in CRBSI, catheter colonization, or catheter-related infection.

SYNTHESIS

The recommended preventive strategies with the strongest supportive evidence are education and training of healthcare providers who insert and maintain catheters; maximal sterile barrier precautions during central venous catheter insertion; use of a 2% chlorhexidine preparation for skin antisepsis; no routine replacement of central venous catheters for prevention of infection; and use of antiseptic/antibiotic-impregnated short-term central venous catheters if the rate of infection is high despite adherence to other strategies (ie, education and training, maximal sterile barrier precautions, and 2% chlorhexidine for skin antisepsis).

CONCLUSION

Successful implementation of these evidence-based interventions can reduce the risk for serious catheter-related infection.
