Complications of Peripheral Venous Access Devices: Prevention, Detection, and Recovery Strategies

Impact of an interventional bundle on complications associated with peripheral venous catheters in elderly patients

PURPOSE

Elderly patients admitted to geriatrics departments often require peripheral venous catheters (PVC), which should be inserted and maintained following a series of preventive recommendations. Our objective was to evaluate the impact of a training bundle comprising measures aimed at reducing complications associated with the use of PVC in elderly patients admitted to a tertiary teaching hospital.

METHODS

We performed a prospective study of patients who received a PVC within 24 h of admission to a geriatrics department. After a 10-month pre-interventional period, we implemented an educational and interventional bundle over a 9-month period. Follow-up was until catheter withdrawal. We analyzed and compared clinical and microbiological data between both study periods.

RESULTS

A total of 344 patients (475 PVC) were included (pre-intervention period, 204 patients (285 PVC); post-intervention period, 140 patients (190 PVC)). No statistically significant differences in demographic characteristics were observed between the study periods. The colonization and phlebitis rates per 1000 admissions in both periods were, respectively, 36.7 vs. 24.3 (p = 0.198) and 81.5 vs. 65.1 (p = 0.457). The main reason for catheter withdrawal was obstruction/malfunctioning (33.3%). Obstruction rate was higher for those inserted in the hand than for those inserted at other sites (55.7% vs. 44.3%, p = 0.045).

CONCLUSIONS

We found no statistically significant differences regarding phlebitis and catheter tip colonization rates. It is necessary to carry out randomized studies assessing the most cost-effective measure to reduce complications associated with PVC.

Ultrarapid Iron Polymaltose Infusions Are Safe for Management of Iron Deficiency

Introduction

Iron deficiency is a common condition, especially among patients with kidney and heart failure and inflammatory bowel disease. Intravenous iron is the preferred method of treatment in these patients, but it usually requires prolonged iron polymaltose infusions or multiple administrations of alternative preparations. The aim of the study was to confirm the safety and patient acceptance of ultrarapid iron polymaltose infusions as an alternative to slower treatments and ferric carboxymaltose.

Method

An open-label, phase 4 safety study was conducted at a tertiary hospital, with consenting participants diagnosed with iron deficiency and requiring iron polymaltose up to 1,500 mg receiving the infusion over 15 min. The acute adverse event (AE) rates and their severities were compared to historical controls of 1- and 4-h iron polymaltose infusions from a retrospective study of 648 patients from the same study site. Delayed AEs as well as participant infusion acceptability were also studied.

Results

Three hundred participants over a 2-year period received ultrarapid infusions of iron polymaltose with an acute AE rate of 18.7% and severe AE rate of 1.0%. The total and mild infusion AE rates were higher compared to those of slower infusions (p < 0.001), but comparable for moderate and severe AEs. Delayed reactions occurred in 12.5% of participants, with over 95% of them preferring repeat ultrarapid infusions if required again.

Conclusion

Iron polymaltose can be safely infused at ultrarapid rates when compared to slower infusions, with similar safety to ferric carboxymaltose, offering greater convenience for patients and reduced healthcare costs.

The effect of warm moist compresses in peripheral intravenous catheter-related phlebitis

PURPOSE

Phlebitis is a common complication in palliative patients. There are limited nursing practices in phlebitis care. The study was conducted to determine the effect of warm moist compresses in patients with peripheral intravenous catheter-related phlebitis.

METHODS

70 patients (35 control and 35 experimental) with phlebitis symptoms who were hospitalized in the palliative clinic of a training and research hospital were recruited for the study. The phlebitis site of the patients in the control and experimental groups were followed for three days. While the control group received routine nursing care, the experimental group received a warm moist compresses at 28 °C for 15 min three times a day for three days in addition to routine nursing care.

RESULTS

According to the results, there was a decrease in the initial and final phlebitis grades between the control and experimental groups, but the difference was not statistically significant (p = 0.957, p = 0.078). In the final evaluation of the phlebitis site, a statistically significant difference was observed in redness, edema width, and pain intensity between the control and experimental groups in favor of the experimental group (p˂0.001, p = 0.006, p˂0.001, respectively).

CONCLUSIONS

It was determined that applying warm water compresses three times a day in phlebitis care had a positive effect on healing.

Effect of rapid cycle deliberate practice in peripheral intravenous catheters insertion training: A simulation experimental study

AIM

to compare the effect of rapid cycle deliberate practice simulation training with skill-training simulation on peripheral intravenous catheter insertion for Licensed Practical Nurses.

BACKGROUND

The use of peripheral intravenous catheters is associated with high rates of complications, although it is widely used in clinical practice. Training strategies to ensure good performance can minimize the risks inherent to this procedure.

DESIGN

A randomized simulation experimental pre-post interventional study.

METHODS

Sixty participants were allocated to intervention (n = 30) or control (n = 30) groups. Participants allocated to the intervention group were trained through the Rapid cycle deliberate practice simulation strategy, while participants in the control group were trained through the skill-training simulation strategy. A pre-test was applied before any intervention and a post-test after intervention. The primary outcome was the performance in the peripheral intravenous catheter insertion skill. The comparison of correct performance in the tests was analyzed intergroup and intragroup. The effect size of the interventions was also analyzed. The t-Student and Mann-Whitney tests compared the difference between the groups. The training effect was calculated by Cohen's dm and Glass's Δ measures.

RESULTS

Performance between the pre-post-test increased from 59.4% to 96% (p < 0.001) in the intervention group and from 57.8% to 93.5% in the control group (p < 0001). There was no statistical difference between the groups after intervention (p = 0225). Cohen's dm measurement was 2.95 and 3.59 in the control and intervention groups, respectively.

CONCLUSIONS

The rapid cycle deliberate practice simulation strategy resulted in Licensed Practical Nurses' performance improvements in peripheral intravenous catheter insertion, evidenced by the increase of correct performance actions in the post-test compared to the pre-test. However, with no statistical difference compared to the skill-training simulation strategy.

Preventing Risks of Infections and Medication Errors in IV therapy (PRIME): a patient safety initiative

BACKGROUND

Two major avoidable reasons for adverse events in hospital are medication errors and intravenous therapy-induced infections or complications. Training for clinical staff and compliance to patient safety principles could address these.

METHODS

Joint Commission International (JCI) consultants created a standardised, 6-month training programme for clinical staff in hospitals. Twenty-one tertiary care hospitals from across south-east Asia took part. JCI trained the clinical consultants, who trained hospital safety champions, who trained nursing staff. Compliance and knowledge were assessed, and monthly audits were conducted.

RESULTS

There was an overall increase of 29% in compliance with parameters around medication preparation and vascular access device management.

CONCLUSION

The programme improved safe practice around preparing medications management and managing vascular access devices. The approach could be employed as a continuous quality improvement initiative for the prevention of medication errors and infusion-associated complications.

Application of epicutaneo-cava catheters with 24G indwelling needles in very low birth weight infants: a safe and simple innovative technique

Background

Epicutaneo-cava catheter (ECC) is an ideal venous access for very low birth weight (VLBW) infants. However, because veins of VLBW infants are thin, ECC catheter is difficult to insert, and the success rate of puncture is low. This study aimed to use ECC with 24G indwelling needles to improve the outcomes of VLBW infants.

Methods

This retrospective study enrolled 121 VLBW infants (birthweight <1,500 g) who required ECC catheterization and were admitted to the Neonatal Intensive Care Unit of the Children's Hospital of Zhejiang University School of Medicine between January 2021 and December 2021. The patients were divided into the indwelling needle group and the conventional technique group according to the technique of ECC. The demographic and treatment data of the two groups were collected, and the success rate of first attempt cannulation of ECC and catheter-related complications of the two groups were analyzed and compared.

Results

There were no significant differences in gender, age, and body weight between the two groups on the day of ECC insertion and venipuncture site. It can be seen through model analysis that the success rate of first-attempt cannulation of ECC in the indwelling needle group was significantly higher than in the conventional technique group. In contrast, average catheterization time and catheterization-related bleeding risk in the indwelling needle group were significantly lower than in the conventional technique group (p = 0.00,and 0.00, respectively). Infection during catheter placement, indwelling catheter duration and catheter-related infection between the two groups (p > 0.05).

Conclusion

Application of ECC with 24G indwelling needles in VLBW infants can improve the success rate of first attempt cannulation of ECC, reduce the time of catheterization and the risk of bleeding, which may be popularized for widespread application.

Safety verification of a new peripheral intravenous catheter placed in the upper arm vein for administration of drugs with high irritant potential

Despite the widespread use of peripheral intravenous catheters, unscheduled catheter failure before completion of treatment occurs frequently. If a large vein is selected, catheter failures may be prevented despite administering a highly irritant drug. In this study, we attempted to use a catheter that can be placed in a large upper arm vein. The new catheter was 88 mm long but had no guidewire to reduce contamination risk. This study aimed to evaluate the safety of the first-in-human trial for the new catheter with the administration of highly irritant drugs. This study was conducted at a university hospital in Tokyo, Japan. Eight Japanese adults were hospitalized adults with planned administration of non-cancer drugs with high irritant potential using a peripheral catheter. A trained nurse catheterized with the new catheter in the upper arm using ultrasonography. The catheterization site was monitored by staff and a research nurse once every 24 hours for up to 7 days. No adverse events or catheter failure occurred and the catheter placement success rate was 100%. In two patients, a temporary occlusion alarm of the infusion pump occurred, possibly due to the flexion of the catheter base. The new peripheral intravenous catheter did not interrupt medical treatments as is common after placement, but safety administered the irritant drugs. However, because this catheter may be easily affected by the contraction of the muscle at the fixation position, the position and method of catheter fixation in the upper arm need to be carefully considered.

Hemodynamic-based Assessment and Management of Cardiogenic Shock

Cardiogenic shock (CS) remains a deadly disease entity challenging patients, caregivers, and communities across the globe. CS can rapidly lead to the development of hypoperfusion and end-organ dysfunction, transforming a predictable hemodynamic event into a potential high-resource, intense, hemometabolic clinical catastrophe. Based on the scalable heterogeneity from a cellular level to healthcare systems in the hemodynamic-based management of patients experiencing CS, we present considerations towards systematic hemodynamic-based transitions in which distinct clinical entities share the common path of early identification and rapid transitions through an adaptive longitudinal situational awareness model of care that influences specific management considerations. Future studies are needed to best understand optimal management of drugs and devices along with engagement of health systems of care for patients with CS.

Vascular Access in Therapeutic Apheresis: One Size Does not Fit All

BACKGROUND

Therapeutic apheresis has been used in treating hematological and non-hematological diseases. For a successful procedure, efficient vascular access is required. Presently, peripheral venous access (PVA), central venous catheterization (CVC), implantable ports, and arteriovenous fistulas (AVFs) are used. This review aims to evaluate different type of access and their pros and cons to help physicians determine the best venous access.

METHODS

The electronic search included PubMed and Google Scholar up to Nov. 2020. The Mesh terms were apheresis, peripheral catheterization, central catheterization, and arteriovenous fistula.

RESULTS

A total of 228 studies were found through database searching. Two independent authors reviewed the articles using their titles and abstracts; 88 articles were selected and the full text was reviewed. Finally, 25 were included. The inclusion criteria were studies incorporating patients with any indication for apheresis.

CONCLUSION

PVA has been promoted in recent years in many centers across the United States to lower the rate of complications associated with vascular access and to make this procedure more accessible. Several factors are involved in selecting appropriate venous access, such as the procedure's duration and frequency, patient's vascular anatomy, and staff's experience. In short-term procedures, temporary vascular access like PVA or CVC is preferred. Permanent vascular access such as AVF, tunneled cuffed central lines, and implantable ports are more beneficial in prolonged treatment period but each patient has to be evaluated individually by apheresis team for the most appropriate method.

Evidence of learning on the insertion and care of peripheral venous catheters in nursing students: A mixed study

OBJECTIVES

1) To assess nursing students' evidence-based knowledge on the use of PVCs, and 2) to examine the perception of learning and teaching strategies aimed at this skill.

BACKGROUND

Insertion and care of Peripheral Venous Catheters (PVCs) are essential skills in undergraduate nursing education. Appropriate knowledge of this skill is crucial to improve clinical practice and patient safety. Therefore, training becomes an enabler for safe practice.

DESIGN

A multi-centre convergent parallel mixed-methods.

SETTING AND PARTICIPANTS

A total of 675 second-, third- and fourth-year nursing students from 3 nursing schools took part in the study.

METHODS

Quantitative data collection used a validated 15-question survey on knowledge of PVC management, and a descriptive and inferential analysis was carried out. Qualitative data were collected via a questionnaire consisting of 4 open-ended questions assessing knowledge, teaching methodologies and scenarios, and points for improvement.

RESULTS

Most participants were female (74.04%), with a mean age of 22.45 (SD = 4.65), who had no experience in the health field (61.8%). They obtained a mean knowledge score of 7.27 (SD = 2.64) out of 15. The students who obtained higher scores had a mean professional experience of 7.96, SD = 2.66 (p 0.000) and were in their final year, with a mean of 8.59, SD = 2.56, (p 0.000). On the other hand, the students assessed their knowledge as basic but improving year by year. They also identified a need to apply more active and experiential methodologies that would allow for reflection.

CONCLUSION

Level of educational level and experience is associated with increased knowledge. In order to improve knowledge, changes must be made in the training process to incorporate methodologies such as simulation and online training. There is a need to develop programmes that favour the alignment of theory with clinical practice.

Hiding in Plain Sight: Peripheral Intravenous Catheter Infections

TOPIC

This article presents an overview of the burden of peripheral intravenous catheter infections and current evidence-based recommendations for prevention.

CLINICAL RELEVANCE

Peripheral intravenous catheters are ubiquitous in most health care settings, fostering an acceptance of the peripheral intravenous catheter as benign and inevitable. This device, however, is far from benign, with reported failure rates as high as 90% from complications such as infection and phlebitis. Although reported rates of bloodstream infection related to peripheral intravenous catheters are much lower than those attributed to central venous catheters, the exponentially higher use of peripheral intravenous catheters indicates that the absolute number of peripheral venous catheter-related bloodstream infections is likely as high as and may surpass the number of central venous catheter-related bloodstream infections, with significant associated morbidity and mortality.

PURPOSE OF PAPER

Sustained improvements in outcomes related to peripheral intravenous catheters will depend on recognition of the root causes of failure and increased commitment to practice patterns consistent with infusion therapy standards of practice, effective education about peripheral intravenous catheters, accurate documentation of all aspects of peripheral intravenous catheter management, and consistent surveillance of patient outcomes related to peripheral intravenous catheters.

CONTENT COVERED

This article reviews the significant burden of peripheral intravenous catheter infections, barriers to effective peripheral intravenous catheter management, and current evidence-based recommendations to prevent this source of patient harm.

Measuring the Validity and Reliability of the Vascular Access Complication Staging and Treatment Instrument in a Pediatric Population

A multiphase study designed with Delphi and observational components was conducted to establish the preliminary validity and reliability of the 2018 Vascular Access Complication Staging and Treatment Instrument in pediatric and neonatal populations from a single, free-standing academic children's hospital. The instrument uses objective measurement criterion to determine the severity of swelling and tissue damage to inform treatment decisions. The results of the study provided preliminary empirical evidence to support a pediatric and neonatal intravenous complication staging instrument to assess degree of swelling and severity of tissue injury. The study also offered preliminary evidence that the instrument was perceived by the nurses who participated in the study to be efficient and easy to use.

Prevention and Treatment of Phlebitis Secondary to the Insertion of a Peripheral Venous Catheter: A Scoping Review from a Nursing Perspective

The objective of this work was to identify available evidence on nursing interventions for the prevention and treatment of phlebitis secondary to the insertion of a peripheral venous catheter. For this, a scoping systematic review was carried out following the guidelines in the PRISMA declaration of documents published between January 2015 and December 2020. The search took place between December 2020 and January 2021. Scielo, Pubmed, Medline, Scopus, WOS, CINHAL, LILACS, and Dialnet databases were consulted, and CASPe, AGREE, and HICPAC tools were used for the critical reading. A total of 52 studies were included to analyze nursing interventions for treatment and prevention. Nursing interventions to prevent phlebitis and ensure a proper catheter use included those related to the maintenance of intravenous therapy, asepsis, and choosing the dressing. With regard to the nursing interventions to treat phlebitis, these were focused on vigilance and caring and also on the use of medical treatment protocols. For the prevention of phlebitis, the highest rated evidence regarding asepsis include the topical use of >0.5% chlorhexidine preparation with 70% alcohol or 2% aqueous chlorhexidine, a proper hygienic hand washing, and the use clean gloves to handle connections and devices. Actions that promote the efficacy and safety of intravenous therapy include maintenance of venous access, infusion volume control, verification of signs of phlebitis during saline solution and medication administration, and constant monitoring. It is recommended to remove any catheter that is not essential. Once discharged from hospital, it will be necessary to warn the patient about signs of phlebitis after PVC removal.

Standardization and Chemical Characterization of Intravenous Therapy in Adult Patients: A Step Further in Medication Safety

BACKGROUND

Intravenous drug administration is associated with potential complications, such as phlebitis. The physiochemical characteristics of the infusate play a very important role in some of these problems.

AIM

The aim of this study was to standardize the dilutions of intravenous drugs most commonly used in hospitalized adult patients and to characterize their pH, osmolarity and cytotoxic nature to better guide the selection of the most appropriate vascular access.

METHODS

The project was conducted in three phases: (i) standardization of intravenous therapy, which was conducted using a modified double-round Delphi method; (ii) characterization of the dilutions agreed on in the previous phase by means of determining the osmolarity and pH of each of the agreed concentrations, and recording the vesicant nature based on the information in literature; and (iii) algorithm proposal for selecting the most appropriate vascular access, taking into account the information gathered in the previous phases.

RESULTS

In total, 112 drugs were standardized and 307 different admixtures were assessed for pH, osmolarity and vesicant nature. Of these, 123 admixtures (40%), had osmolarity values >600 mOsm/L, pH < 4 or > 9, or were classified as vesicants. In these cases, selection of the most suitable route of infusion and vascular access device is crucial to minimize the risk of phlebitis-type complications.

CONCLUSIONS

Increasing safety of intravenous therapy should be a priority in the healthcare settings. Knowing the characteristics of drugs to assess the risk involved in their administration related to their physicochemical nature may be useful to guide decision making regarding the most appropriate vascular access and devices.

The influence of low-fidelity simulator training on canine peripheral venous puncture procedure

Background and Aim:

Blood collection from dogs is the most commonly performed procedure in the medical clinic. However, different factors can interfere with the quality of the material collected, potentially causing complications for patients. Simulated skill training is a teaching strategy designed to provide early training to students, develop their skills and self-confidence, and increase the procedure’s success while reducing complications. Therefore, the aim of this study was to evaluate skill training using a low-fidelity simulator in the peripheral venipuncture procedure and examine the training’s influence on the in vivo procedure.

Materials and Methods:

To assess skill training, this study used a low-fidelity simulator in the peripheral venipuncture procedure and examines the training’s effect on the in vivo procedure. In total, 100 dogs, 65 undergraduate students, 3 veterinarians, and 4 previously trained evaluators participated. The canine in vivo venipuncture procedure was evaluated both before and after the simulated skill training and the low-fidelity simulator training. Data were collected on participants’ self-confidence levels.

Results:

Local complications occurred during in vivo practice; however, after training, they decreased. Gloves were more frequently used during the procedure, resulting in a reduction of both harvest attempts and complications, as well as increased levels of self-confidence in post-training participants. The simulator developed had low fidelity, low cost, and was easy to create.

Conclusion:

Skill training in peripheral venipuncture using a low-fidelity simulator positively influences student learning, increases their self-confidence during in vivo harvesting, and reduces the complications of the procedure, improving patient well-being.

Usability Assessment of an Innovative Device in Infusion Therapy: A Mix-Method Approach Study

Background: Flushing a venous access device is an important procedure to maintain their patency and prevent malfunctioning and complications. An innovative double-chamber syringe was developed, allowing for the assessment of catheter patency, drug delivery and final flush. This study aims to assess the usability of this new device, considering three development stages (concept, semi-functional prototype, functional prototype). Methods: An iterative methodology based on a mix-method design (qualitative and quantitative) enabled the assessment of the devices’ usability by their primary end-users. A usability questionnaire was developed and applied, along with focus groups and individual interviews to nurses. Results: The usability questionnaire integrated 42 items focused on four dimensions (usefulness; ease of use; ease of learning; satisfaction and intention to use). The initial psychometric findings indicate a good internal consistency and the conceptual relevance of the items. The scores seem to be sensitive to the usability evaluation of the medical devices in different stages of product development (with lower values on functional prototype evaluation), and related to nurses’ perceptions about functional and ergonomic characteristics. Conclusions: Quantitative and qualitative data provided a comprehensive overview of the double-chamber syringes’ usability from the nurses’ point of view, informing us of features that must be addressed.

Collaborative strategic initiative between a university and hospital network group: Advanced nurse/midwife practice forum

BACKGROUND

The Faculty of Nursing and Midwifery, one of a few nursing and midwifery faculties worldwide, was established in 1974 by Ms Mary Frances Crowley, for postgraduate nursing education, and is situated within the Royal College of Surgeons in Ireland, University of Medicine and Health Sciences. The RCSI operates through a network group of university hospitals: Beaumont, Connolly, Drogheda, Cavan, Monaghan and the Rotunda. Combined these hospitals have 120 registered and candidate ANP/AMPs and caters for general, psychiatric, children and maternity patients/clients. The drive to establish the forum between the faculty and the six Dublin hospitals was to build capacity among advanced nurse practitioners and advanced midwife practitioners (ANP/AMPs) who are seen as intelligent consumers of evidence-based research and safe practice. The SCAPE report identified research as the single domain that was underdeveloped within the ANP role, in the study exploring the role of ANPs and CNSs. Latterly, the Nursing and Midwifery Board of Ireland highlighted research as a vital component of the ANP/AMP role in its standards for advanced nurse and midwife practice. The faculty acted collaboratively to introduce an ANP/AMP forum to support advanced practitioners working in the university hospital group in their education and professional development, support the expansion of their knowledge base through practice-based enquiry and research and act as a conduit for interactions between ANPs/AMPs by keeping them up to date with practice and research.

METHODS

The Initiation phase was undertaken through a survey of needs; Implementation phase by extensive literature review and research-based newsletters sent to individuals by the forum coordinator; and the Evaluation phase through focus groups.

Peripheral vascular access for therapeutic plasma exchange: A practical approach to increased utilization and selecting the most appropriate vascular access

BACKGROUND

Therapeutic plasma exchange (TPE) is used in the treatment of many diseases. At present, peripheral vascular access (PVA) is an underutilized method of vascular access in TPE. It should be considered more frequently due its relatively low risk for adverse events, particularly infections.

METHODS

The Advancing Vascular Access in Apheresis Working Group met in December 2017 for an extensive review and discussion of vascular access for TPE and developed a "road map" providing detailed information regarding clinical situations in which PVA-based TPE would and would not be appropriate.

RESULTS

The road map is consistent with current recommendations that PVA should be used in combination with TPE whenever possible. PVA should be considered for patients who do not have existing central lines and who are stable. The patient should have peripheral veins that will allow for adequate treatment and must be able to comply with the process of achieving and maintaining peripheral access. There should be expert clinical assessment of veins, and this evaluation may include ultrasound and/or near infrared evaluation. Conditions that would prompt a switch from PVA to an alternate method of venous access include loss of venous access, patient preference, or development of a requirement for very frequent treatment over a long period of time.

CONCLUSIONS

While PVA is not suitable for all patients requiring TPE, it has significant safety advantages over other approaches and should be employed whenever possible.

Randomized clinical trial analyzing maintenance of peripheral venous catheters in an internal medicine unit: Heparin vs. saline

Background

Peripheral venous catheters (PVCs) require adequate maintenance based on heparin or saline locks in order to prevent complications. Heparin has proven effective in central venous catheters, although its use in PVCs remains controversial. Our hypothesis was that saline locks are as effective as heparin locks in preventing problems with PVCs. The objective of the present study was to compare phlebitis and catheter tip colonization rates between PVCs locked with saline and those locked with heparin in patients admitted to an internal medicine department (IMD).

Methods

We performed a 19-month prospective, controlled, open-label, randomized clinical study of patients with at least 1 PVC admitted to the IMD of our hospital. The patients were randomized to receive saline solution (PosiFlush^®, group A) or heparin (Fibrilin^®, group B) for daily maintenance of the PVC. Clinical and microbiological data were monitored to investigate the frequency of phlebitis, catheter tip colonization, and catheter-related bloodstream infection (C-RBSI), as well as crude mortality, days of hospital stay, and days of antimicrobial treatment.

Results

We assessed 339 PVCs (241 patients), of which 192 (56.6%) were locked with saline (group A) and 147 (43.4%) with heparin (group B). The main demographic characteristics of the patients were distributed equally between the 2 study groups. The median (IQR) catheter days was 5 (3–8) for both groups (p = 0.64). The frequency of phlebitis was 17.7% for group A and 13.3% for group B (p = 0.30). The frequency of colonization of PVC tips was 14.6% and 12.2% in groups A and B, respectively (p = 0.63). Only 2 episodes of C-RBSI were detected (1 patient in group A). Saline lock was not an independent factor for phlebitis or catheter colonization.

Conclusions

Our study revealed no statistically significant differences in the frequency of phlebitis and catheter tip colonization between PVCs locked with saline and PVCs locked with heparin. We suggest that PVC can be maintained with saline solution, as it is safer and cheaper than heparin.

Cost-Effectiveness Analysis of Low-Cost, Domestic Short Peripheral Catheters Versus Higher-Priced, Imported Short Peripheral Catheters

This prospective study has been designed with the hypothesis that low unit price does not necessarily mean cost-effectiveness. Low-cost, domestic short peripheral catheters (SPCs) and higher-priced, imported SPCs were compared in 2 different time periods. With the use of the higher-priced, imported SPCs, the rate of successful insertion on first attempt was increased (P < .001), and the development of complications was reduced (P < .001). The study revealed that $345 was saved per 1000 catheters when the catheter with the higher unit price was chosen. Although the domestic SPCs had a low unit price, their use resulted in greater health care expenses.

Umbilical vein catheterization through Wharton's jelly: A possibility for a fast and safe way to deliver treatments in the delivery room?

Fast and safe venous access can be a critical issue in the delivery room during neonatal cardiopulmonary resuscitation or before endotracheal intubation. Here, we describe a new method to inject drugs using the umbilical vein, directly punctured through Wharton's jelly, performed in ten newborns between November 2016 and May 2018. The umbilical vein was identified and punctured easily and a reflux was obtained in all patients. The treatments were efficient in all but two patients, which was imputable to the method in one patient. We describe a new route for administration of drugs that has been successfully used in neonates.
