Peripherally inserted central catheter (PICC) is a widely used technique in oncology chemotherapy, characterized by safety, reliability, and long dwell time. However, a catheter can break due to various causes. When an acute rupture occurs, it always lead to sever complications which may threaten patients\' safety and potentially result in medical disputes. In this study, we collected and analyzed 3 cases of PICC line breakage causing drug leakage in our hospital from 2018 to 2023. All these 3 cases were postoperative breast cancer patients accepting chemotherapy, with 2 cases involving external partial breakage and 1 case involving internal partial breakage. Due to timely and appropriate management, no acute rupture occurred. We propose some ideas such as selecting high-quality catheter materials and avoiding over extension or repeated bending are crucial in preventing PICC line breakage. In addition, we also recommend establishing a standardized and scientific management pattern of PICC to ensure the safety and effectiveness of its clinical application, including comprehensive assessment, \"four-element\" intervention, and continuous evaluation.

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.

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.

OBJECTIVE: This review aims to compare the performance of available risk assessment models (RAMs) for predicting peripherally inserted central catheter-related venous thrombosis (PICC-RVT) in adult patients with cancer.
METHODS: A systematic search was conducted across ten databases from inception to October 20, 2023. Studies were eligible if they compared the accuracy of a RAM to that of another RAM for predicting the risk of PICC-RVT in adult patients with cancer. Two reviewers independently performed the study selection, data extraction and risk of bias assessments. A Bayesian network meta-analysis (NMA) was used to evaluate the performance of the RAMs.
RESULTS: A total of 1931 studies were screened, and 7 studies with 10 RAMs were included in the review. The most widely used RAMs were the Caprini (4 studies), Padua prediction score (3 studies), Autar (3 studies), Michigan risk score (2 studies) and Seeley score (2 studies). The sensitivity, specificity and accuracy varied markedly between the models. Notably, the Caprini score achieved higher sensitivity than 4 RAMs (Wells, Revised Geneva, modified MRS, MRS). The Michigan risk score had greater specificity than did the other 6 RAMs (Caprini, Autar, Padua, Seeley, the novel RAM, Wells). The predictive accuracy of the MRS is significantly greater than that of the Caprini and Autar RAM.
CONCLUSIONS: The MRS could be the most accurate RAM for identifying patients at high risk of PICC-RVT. However, as limited studies are available, more rigorous studies should be conducted to examine the accuracy of the Michigan risk score for PICC-RVT in different contexts.

Background: In order to reduce the risk of leakage of cytotoxic agents, peripherally inserted central catheters (PICC) are widely used in patients diagnosed with malignancy before chemotherapy. While inflammation has been demonstrated to be associated with deep vein thrombosis (DVT), the connection between systemic immune inflammation indexes and the formation of PICC-DVT remains unclear. Purpose: This study aims to evaluate the association between PICC-DVT and systemic immune inflammation indexes including platelet-to-lymphocyte ratio (PLR), systemic immune-inflammatory index (SII), and systemic inflammatory response index (SIRI). Methods: From August 2018 to October 2021, we enrolled consecutive patients diagnosed with malignancy who underwent PICC implantation before chemotherapy. DVT was assessed using color Doppler ultrasonography. Results: Among the 513 patients, 57 patients (11.1%) developed PICC-DVT. The optimal cutoff values for PLR, SII and SIRI were 260.1, 1318.7, and 2.7, respectively. Based on the multiple logistic regression analysis, correlations were found between PICC-DVT and elevated PLR (p = .014), SII (p = .012), and SIRI (p = .022). Patients with malignancy having higher values of PLR, SII or SIRI tended to be more likely to develop PICC-DVT. Conclusions: The systemic immune inflammation indexes increases the risk of PICC-DVT and could be used as auxiliary predictive tests for PICC-DVT.

UNASSIGNED: To establish a predictive modeling for the risk of bloodstream infection associated with peripherally inserted central catheter (PICC).
UNASSIGNED: Patients receiving PICC treatment in Shenzhen People\'s Hospital from June 2020 to December 2020 were retrospectively enrolled and divided into the infection group and the non-infection group according to the presence and absence of PICC-related infections. Then, relevant clinical information of patients was collected and the predictors of PICC-related infection were screened by the least absolute shrinkage and selection operator regression (LASSO) model. Besides, multivariate logistic regression was used to analyze the influencing factors of PICC-related infection, A nomogram was constructed based on the results of the multivariate analysis. Ultimately, a receiver operating characteristic (ROC) curve was plotted to analyze the application value of influencing factors to predict PICC-related infections.
UNASSIGNED: A total of 505 patients were included, including 75 patients with PICC-related infections (14.85%). The main pathogen was gram-positive cocci. The predictors screened by LASSO included age >60 years, catheter movement, catheter maintenance cycle, insertion technique, immune function, complications, and body temperature ≥37.2 °C before PICC placement. Multivariate logistic regression analysis showed that independent risk factors of infections related to PICC included age >60 years [odds ratio (OR) = 1.722; 95% confidence interval (CI) = 1.312-3.579; P = 0.006], catheter movement (OR = 1.313; 95% CI = 1.119-3.240; P = 0.014), catheter maintenance cycle >7 days (OR = 2.199; 95% CI = 1.677-4.653; P = 0.000), direct insertion (OR = 1.036; 95% CI = 1.019-2.743; P = 0.000), poor immune function (OR = 2.322; 95% CI = 2.012-4.579; P = 0.000), complications (OR = 1.611; 95% CI = 1.133-3.454; P = 0.019), and body temperature ≥37.2 °C before PICC placement (OR = 1.713; 95% CI = 1.172-3.654; P = 0.012). Besides, the area under the ROC curve was 0.889.
UNASSIGNED: PICC-related infections are associated with factors such as age >60 years, catheter movement, catheter maintenance cycle, insertion technique, immune function, complications, and body temperature ≥37.2 °C before PICC placement. Additionally, the LASSO model is moderately predictive for predicting the occurrence of PICC-related infections.

Peripherally inserted central catheters are widely used in patients with extensive burns, with the guidelines recommending insertion through unburned skin. This case report describes a patient who was burned over 88% of their surface area and suffered severe inhalation injury. For him, the popliteal vein was the only vein on unburned skin available for catheter catheterization. Based on evidence, we successfully placed a peripherally inserted central catheter through the popliteal vein under ultrasound while the patient was in the prone position and avoided associated complications.

BACKGROUND: Peripherally inserted central catheters (PICCs) are an essential infusion route for oncology patients receiving intravenous treatments, but lower extremity venipuncture is the preferred technique for patients with superior vena cava syndrome (SVCS). We report the case of a patient with a lower extremity PICC ectopic to the ascending lumbar vein, to indicate and verify PICC catheterisation in the lower extremity is safe and feasible. And hope to provide different perspectives for clinical PICC venipuncture to get the attention of peers.
METHODS: On 24 August 2022, a 58-year-old male was admitted to our department due to an intermittent cough persisting for over a month, which worsened 10 d prior. Imaging and laboratory investigations suggested the patient with pulmonary malignancy and SVCS. Chemotherapy was not an absolute contraindication in this patient. Lower extremity venipuncture is the preferred technique because administering upper extremity venous transfusion to patients with SVCS can exacerbate oedema in the head, neck, and upper extremities. The patient and his family were informed about the procedure, and informed consent was obtained. After successful puncture and prompt treatment, the patient was discharged, experiencing some relief from symptoms.
CONCLUSIONS: Inferior vena cava catheterisation is rare and important for cancer patients with SVCS, particularly in complex situations involving ectopic placement.

OBJECTIVE: To identify the trends in the prevalence of peripherally inserted central catheter (PICC) related complications in cancer patients and explore the risk factors for complications and occurrence speed.
METHODS: A total of 3573 cancer patients with PICC were recruited at 17 hospitals from 2016 to 2022. Logistic and COX regression were performed to identify influencing factors of PICC-related complications and incidence speed, respectively.
RESULTS: The proportion of symptomatic PICC-related thrombosis, phlebitis, and infections reported had decreased from 59.1% (in 2017), 11.9% (in 2016), and 11.1% (in 2016) to 15.3% (in 2022), 2.9% (in 2022), and 7.4% (in 2022), and adhesive-related skin injuries and bleeding/oozing reported had increased from 4.8% (in 2016) and 0.0% (in 2016) to 45.5% (in 2022) and 3.4% (in 2022), respectively. Catheter occlusion showed a trend of first increasing and then decreasing from 2.4 (in 2016) to 12.0 (in 2020) to 5.8% (in 2022). Logistic regression showed that hospital level, nature, the patient\'s gender, age, diagnosis, history of deep vein catheterization, chemotherapy drug administration, and type of PICC were influencing factors of complications. COX regression showed that the patient\'s gender, age, diagnosis, history of deep vein thrombosis and thrombophlebitis, history of deep vein catheterization, chemotherapy drug administration, type of PICC, type of connector, and StatLock used for fixation were influencing factors of incidence speed.
CONCLUSIONS: The composition ratios of PICC-related complications in cancer patients in China have changed in recent years. Chemotherapy drug administration was a significant risk factor accelerating the occurrence of complications. Maintenance factors had the maximum weight on the COX model, followed by patient factors. It is suggested that patients with high-risk factors be closely monitored and proper maintenance be performed to prevent and delay the occurrence of PICC-related complications.

Objective: This study was conducted to analyze the effectiveness of multidisciplinary cooperative continuous nursing combined with psychological nursing intervention in multiple myeloma (MM) patients undergoing peripherally inserted central catheter (PICC). Methods: The Numerical Pain Rating Scale (NPRS), Anxiety Self-Assessment Scale (SAS), Depression Self-Assessment Scale (SDS) and Revised Piper Fatigue Scale (PFS-R), Self-Care Ability Scale (ESCA), Quality of Life Core Questionnaire (QLQ-C30), incidence of unplanned extubation of PICC, total incidence of catheter-related complications and satisfaction with nursing were compared between the two groups of patients in a prospective study. Results: Patients in the observation group had reduced NPRS, SAS, SDS and PFS-R scores, total incidence of unplanned extubation of PICC and the total incidence of catheter-related complications, and a higher nursing satisfaction rate in comparison to those in the control group. Conclusion: Multidisciplinary cooperative continuous nursing combined with psychological nursing interventions can relieve pain in MM patients.
