BACKGROUND: Catheter-related thrombosis is a common complication of the peripherally inserted central catheter (PICC) in neonates, leading to unintended tube removal and significantly affecting neonatal health and safety. Despite widespread reporting on the estimated occurrence and factors contributing to neonatal PICC-related thrombosis, these findings have not been synthesized.
OBJECTIVE: The purpose of this study was to determine the incidence and risk factors of neonatal PICC-related thrombosis.
METHODS: Systematic literature review and meta-analysis.
METHODS: Two independent researchers systematically explored multiple databases-such as PubMed, Medline, Embase and the Cochrane Library-from their inception until October 2023. Our study aggregates and scrutinizes studies specifically addressing the incidence and risk factors of neonatal PICC-related thrombosis. Employing the RevMan 5.3 software, a meta-analysis was executed to determine the incidence of both thrombosis and odds ratios (OR), accompanied by their respective 95% confidence intervals (CI) for the risk factors.
RESULTS: A total of 327 articles were screened, and data from 24 studies were used in synthesis. Neonatal PICC-related thrombosis incidence varied from 0.23% to 17.91%. The pooled incidence was 2% (95% CI: 1%-2%; I2 = 94%; p < .0001). The study identified 12 risk factors, including insertion sites in the lower extremities (OR = 0.22; 95% CI: 0.09-0.56; p = .001), gestational age <28 weeks, abdominal pathology, fresh frozen plasma by day 5 > 50 mL/kg, PICC tip location (proximal placement), two lumens, three lumens, prolonged hospital stay, infection, mothers\' use of anticoagulants, patients with cardiac insufficiency and being twin-to-twin transfusion syndrome donor.
CONCLUSIONS: The analysis indicates an overall pooled incidence of neonatal PICC-related thrombosis of 2%. Twelve factors were identified as risks associated with neonatal PICC-related thrombosis. Understanding the risk factors can provide evidence-based recommendations for improving awareness, control and treatment and better nursing management.
CONCLUSIONS: This systematic review and meta-analysis illuminates the incidence and risk factors linked to neonatal PICC-related thrombosis, delivering essential insights pivotal for clinical decision-making and enhancing patient care within neonatal health care settings.

BACKGROUND: Peripherally inserted central catheters (PICCs) and midline catheters (MCs) may offer convenient intravenous access, but evidence to support their place in palliative care is limited. This review aimed to assess catheter indications, utilization, complications, dwell time, and patient experiences in cancer patients receiving palliative care.
METHODS: A systematic search for studies on catheter utilization for supportive or symptom treatment was conducted in Medline, Embase, CINAHL, Web of Science, Cochrane, and CENTRAL databases. Studies with a study population or a subgroup of palliative care cancer patients were included. Study quality was assessed using the Effective Public Health Practice Quality assessment tool.
RESULTS: Of 7631 unique titles, 17 articles were examined in detail, all published between 2002 and 2022. Median catheter dwell time varied from 15 to 194 days, the longest when utilized for home parenteral nutrition. For pain and symptom management, the typical duration was 2-4 weeks, often until the patient\'s death. Complication rates were minimal, with thrombosis, infections, and occlusion ranging from 0 to 2.46 incidents per 1000 catheter days. In studies from palliative care services, patients reported minimal distress during procedures and high user satisfaction. Quality of life assessments post-procedure improved, possibly influenced by concurrent specialist palliative care provision. All studies were assessed to be of moderate or weak quality.
CONCLUSIONS: PICC and MC are safe and valuable tools in palliative care cancer patients who would benefit from intravenous access for symptom management. Further studies are needed to clarify indications for PICC or MC in palliative care.

UNASSIGNED: Peripherally inserted central catheters (PICCs) are frequently utilized for extended intravenous treatments. However, complications such as incorrect placement into the azygos vein can result in significant health issues. A thorough understanding of these aspects is crucial to enhance the safety and effectiveness of PICC procedures, thereby improving patient care outcomes.
UNASSIGNED: The research was conducted on a cohort of 12 patients who experienced PICC malposition into the azygos vein. Systematically reviewed information on classification, imaging manifestations, potential influencing factors, and methods for identification, prevention, and management.
UNASSIGNED: The analysis uncovered two PICC malposition classifications within the azygos vein, each with unique imaging characteristics. It also pinpointed several factors influencing malposition, offering valuable insight into potential risks. Moreover, it established effective detection methods, underscoring the significance of imaging techniques. Additionally, it outlined strategies for preventing and managing PICC malposition in the azygos vein, enhancing overall comprehension of the issue.
UNASSIGNED: The findings emphasize the importance of taking a proactive stance to avoid malposition and stress the necessity of prompt and precise intervention when malposition does happen, thereby enhancing the safety and effectiveness of PICC processes.

(1) Background: Central venous access devices (CVADs) have been commonly employed during various courses of anticancer treatment. Currently, there are a few types of clinically available CVADs, which are associated with short-term and long-term complications. However, little is known about the complication rates when CVADs are used only in palliative care settings. We therefore performed a systematic review and meta-analysis of all the published literature to evaluate the complication rates of CVADs in this clinical setting. (2) Methods: A systematic review and meta-analysis were conducted to identify publications from PubMed/MEDLINE, Embase (Ovid), Scopus, Cochrane Library, CINAHL, Google Scholar, and trial registries. Publications reporting the complication rates of PICCs, central lines, and PORTs in palliative settings for terminally ill cancer patients were included, while those on the use of systemic anticancer therapy and peripheral venous catheters were excluded. The outcome measures included overall complication rate, rate of catheter-related bloodstream infection (CRBSI), and rate of thromboembolism (TE). This systematic review was registered with PROSPERO (CRD42023404489). (3) Results: Five publications with 327 patients were analyzed, including four studies on PICCs and one study on central lines. No studies on PORTs were eligible for analysis. The overall complication rate for PICCs (pooled estimate 7.02%, 95% CI 0.27-19.10) was higher than that for central lines (1.44%, 95% CI 0.30-4.14, p = 0.002). The risk of CRBSI with PICCs (2.03%, 95% CI 0.00-9.62) was also higher than that with central lines (0.96%, 95% CI 0.12-3.41, p = 0.046). PICCs also had a trend of a higher risk of TE (2.10%, 95% CI 0.00-12.22) compared to central lines (0.48%, 95% CI 0.01-2.64, p = 0.061). (4) Conclusions: PICCs for palliative cancer care were found to have greater complications than central lines. This might aid in the formulation of future recommendation guidelines on the choice of CVAD in this setting.

OBJECTIVE: Some cancer patients in palliative care require intravenous administration of symptom relieving drugs. Peripherally inserted central catheters (PICCs) and midline catheters (MCs) provide easy and accessible intravenous access. However, limited evidence supports the use of these devices in palliative care. The aim was to assess the use, safety, and efficacy of PICC and MC in this patient population.
METHODS: A retrospective study of all palliative care cancer patients who received PICC or MC at the Department of Palliative Medicine at Akershus University Hospital between 2020 and 2022.
RESULTS: A total of 374 patients were included; 239 patients received a PICC and 135 an MC with a total catheterization duration of 11,698 days. The catheters remained in place until death in 91% of patients, with a median catheter dwell time of 21 days for PICCs and 2 days for MCs. The complication rate was 3.3 per 1000 catheter days, with minor bleeding and accidental dislocation as the most common. The catheters were utilized primarily for opioids and other symptom directed treatments, and 89% of patients received a patient or nurse-controlled analgesia pump. Patients with PICC or MC discharged to home or nursing homes spent 81% of their time out of hospital.
CONCLUSIONS: PICC and MC provide safe parenteral access for palliative care cancer patients where intravenous symptom treatment is indicated. Their use can facilitate intravenous symptom treatment beyond the confines of a hospital and supplement the traditional practice relying on subcutaneous administration.

Chest radiography after peripherally inserted central catheter insertion in infants is the reference standard method for verifying catheter tip position. The utilisation of ultrasound (US) for catheter placement confirmation in the neonatal and paediatric population has been the focus of many recent studies.
In this systematic review we investigated the diagnostic accuracy of US for peripherally inserted central catheter tip confirmation in infants in the neonatal intensive care unit (NICU) MATERIALS AND METHODS: We conducted a systematic literature search of multiple databases. The study selection yielded eight articles, all of which had acceptable quality and homogeneity for inclusion in the meta-analysis. Sensitivity and specificity values were reported together with their respective 95% confidence intervals (CI).
After synthesising the eligible studies, we found that US had a sensitivity of 95.2% (95% CI 91.9-97.4%) and specificity of 71.4% (95% CI 59.4-81.6%) for confirming catheter tip position.
Analyses indicated that US is an excellent imaging test for localising catheter tip position in the NICU when compared to radiography. Ultrasonography is a sensitive, specific and timely imaging modality for confirming PICC tip position. In cases where US is unable to locate malpositioned PICC tips, a chest or combined chest-abdominal radiograph should be performed.

OBJECTIVE: Peripherally inserted central catheters (PICC) guarantee a stable and safe vascular access to administer irritants or vesicants therapies. However, they may occasionally be affected by relevant thrombotic complications especially in patients with hypercoagulability such as oncological patients. Among the identification of independent risk factors, the role of body mass index (BMI) ≥25 kg/m2 is now emerging in literature with conflicting results. The aim of this systematic review is to analyze the available scientific literature in order to determine whether BMI could represent a risk factor in the development of thromboembolic event among cancer patients with PICCs.
METHODS: A scientific literature review was performed in Pubmed, Embase and Cinahl from Jan 1, 2010 to September 10, 2020 in which we identified 100 records. Of these, 88 were excluded and 14 were reviewed in full text. Among the reviewed records, 6 articles satisfied the inclusion criteria for analysis. These criteria included the English language, oncological patients with PICCs, the evaluation of catheter-related thrombosis as well as the stratification of patients according to BMI. Studies off topic and lacking data on PICC related complications among overweight and underweight patients were excluded. The includedstudies, judged with Newcastle-Ottawa Scale, was fair-lower quality. The primary endpoint was the relative risk (RR) of PICC-related thrombosis of overweight/obese vs normal weight/underweight (i.e., BMI ≥25 vs <25 kg/m2) in cancer patients.
RESULTS: A total of 2431 patients were included in the analysis. Overall, 15.1% of patients developed PICC-related thrombosis within a median time of 23.2 days (range 11.0-42.5) after PICC implantation. Concerning BMI, 52.6% of the entire population was overweight/obese. We assessed the proportion of patients with PICC-related thrombotic events in the two groups, with 28% (95% CI, 12%-45%) of events registered in the overweight/obese patients cohort, and 13% (95% CI, 6%-19%) in the normal weight/underweight cohort. The pooled relative risk (RR) was 2.06 (95% CI, 1.21-3.49, p<0.001) in overweight/obese vs normal weight/underweight patients.
CONCLUSIONS: This review showed a two-fold risk of thrombosis in overweight/obese compared to normal weight/underweight oncological patients with PICCs. Underweight condition could also play a role in thrombosis development, especially in nasopharyngeal and digestive system cancer. Future prospective studies are needed to achieve reliable results and produce useful conclusion.

Totally implantable venous access ports (PORTs) and peripherally inserted central catheters (PICCs) are associated with an increased risk of venous thromboembolism (VTE). It is not known which type of catheter is most at risk of thrombosis.
We aimed to study the incidence of PORT-related VTE and PICC-related VTE in cancer patients by a meta-analysis.
A systematic search was performed using PubMed, Embase, Web of Science and the Cochrane Library. Cohort studies and randomized controlled trials (RCTs) comparing PORT-related VTE and PICC-related VTE in cancer patients were included. Quality was assessed using the Cochrane Collaboration tool for RCTs and the Newcastle-Ottawa Scale (NOS) for cohort studies. Random-effects meta-analysis was used to calculate odd ratio (OR). Sensitivity and subgroup analyses were conducted.
In total, 22 studies comprising 11,940 patients were retrieved. Our meta-analysis of 22 studies suggested that the risk of PORT-related VTE was lower than that of PICC-related VTE in cancer patients (OR = 0.38, 95% CI: 0.25-0.58). The subgroup analysis showed that the risk of PORT-related VTE and PICC-related VTE is different in different regions. In the non-Asian countries, PORTs were associated with a decreased risk of VTE compared with PICCs. (OR = 0.41, 95%CI: 0.27-0.61). However, there was no significant difference in the risk of PORT-related VTE and PICC-related VTE in the Asian countries (OR = 0.23, 95% CI: 0.05-1.12).
PORTs are associated with a lower risk of VTE than PICCs in cancer patients. The risk of VTE and benefits should be considered when selecting PORTs or PICCs for cancer patients.

Peripherally inserted central catheters (PICCs) are becoming common and effective in acute and critical care settings recently. Burn patients need special considerations because of restricted insertion sites, burn wounds, hyper coagulation, high infection rates and others. However, the safety of PICCs in burn patients are not well elucidated and no related protocol has been formed. This study aims to investigate the thrombosis and infections of PICCs in burn patients.
This was a single center retrospective study and a systematic review. All the burn patients with PICCs between January 1, 2018 and December 31, 2020 were included. A systematic search of Medline, PubMed, EMBASE and Web of Science was performed from inception to 4 June 2021 following PRISMA guidelines. Upper extremity vein thrombosis (UEVT) and central line-associated bloodstream infection (CLABSI) were the main outcome.
A total of 85 successful PICCs in 78 patients were included. Most patients were male (79.5%), adults(80.8%) and injured by flame(74.4%). The mean TBSA was 50.3% and 76.9% of patients had TBSA more than 30%. Most PICCs were punctured once (60.0%) and inserted less than 30 days after injury (80.0%) through basilar vein (70.6%). The overall line days were 2195 days and the mean line days was 25.8 ± 18.3 days. Six PICCs were complicated by UEVT (7.1%) in 21.2 ± 17.3 days after insertion. Patients with UEVT had significantly higher rate of bacteremia and later insertions than those without UEVT. One patient developed CLABSI and the CLABSI rate was 1.2% and 0.5 per 1000 line days. Six PICCs had catheter colonization. No significant risk factors were identified. Five articles involving 293 patients and 319 PICCs were ultimately evaluated in systematic review. The overall incidence of UEVT was 3.2% and CLABSI was 6.9% in burn populations.
PICCs in burn patients had acceptable incidence of UEVT and CLABSI with relative long line durations. A standardized PICC guideline for burn patients is required to further improve the feasibility and safety of PICCs.

Accessing the veins for blood delivery, sampling or nutrition is a critical factor in the process of care and management of pediatric patients. In this regard, the peripherally inserted central catheter (PICC) is one of the main alternatives which could be applied effectively as traditional central venous devices in neonates and adults. Due to their essential role in providing safe central venous entry, PICCs could be applied extensively in patients who are critically ill. The main aims of the present study are to review approximately all relevant publications concerning PICC procedures, any possible complications, and the most appropriate decision for preventing these complications due to their high mortality rate. We carried out a comprehensive search on PubMed, HubMed, EMBASE, MEDLINE, Science Direct, Scopus, MEDLINE, and EMBASE databases for identifying the most relevant publications related to potential complications following the application and insertion of PICCs in hospitalized children and infants. Through appropriate care of catheters, the rate of possible infectious, mechanical and thrombotic complications would decrease considerably compared to those patients who received traditional central venous catheters. However, the process of vascular access in neonatal and children is very challenging. Any delay or denying treatment due to the lack of vascular access is intolerable. In this regard, anesthesiologists must achieve extra knowledge of various vascular devices.
