RESUMO
BACKGROUND: The incidence and risk factors of peripherally inserted central catheter-related thrombosis in patients with breast cancer have not been fully elucidated. METHOD: Meta-analysis was performed by searching all studies on the incidence of peripherally inserted central catheter-associated thrombosis and risk factors for its formation in breast cancer patients from the establishment of the database to May 2023, including PubMed, Embase, Web of Science, China Knowledge Network, China Biomedical Literature Service System (SinoMed) and Wanfang databases. Then the incidence of peripherally inserted central catheter-related thrombosis and risk factors for its formation were analyzed in breast cancer patients. RESULTS: A total of 15 articles were included, involving 8635 patients. The total incidence of peripherally inserted central catheter-related thrombosis in breast cancer patients was 7.0% (95% confidence interval: 4.0-13.0%) and 12.9% (95% confidence interval: 7.0-22.5%) after correction. Thirty-two risk factors were included, and eight risk factors could be combined. Among these risk factors, there were statistically significant differences (P < 0.05) in body mass index ≥ 25 (odds ratio = 6.319, 95% confidence interval: 2.733-14.613; P < 0.001), D-dimer >500 ng/ml (odds ratio = 1.436, 95% confidence interval: 1.113-1.854; P = 0.005), increased fibrinogen (odds ratio = 4.733, 95% confidence interval: 1.562-14.346; P = 0.006), elevated platelet count (odds ratio = 4.134, 95% confidence interval: 2.694-6.346; P < 0.001) and catheter malposition (odds ratio = 8.475, 95% confidence interval: 2.761-26.011; P < 0.001). CONCLUSION: The incidence rate of peripherally inserted central catheter-related thrombosis in breast cancer patients was 7.0% (95% confidence interval: 4.0-13.0%). Body mass index ≥ 25, D-dimer >500 ng/ml, elevated fibrinogen, elevated platelet count and catheter malposition were risk factors for peripherally inserted central catheter-related thrombosis in breast cancer patients.

BACKGROUND: Breast cancer patients undergoing chemotherapy via peripherally inserted central catheter often experience serious behavioral and psychological challenges, with uncertainty and cancer-related fatigue being prevalent issues that profoundly impact prognosis. Therefore, this study aimed to investigate the relationship between uncertainty and cancer-related fatigue by employing a chain mediation model to examine the potential mediating roles of psychological resilience and self-care. METHODS: A cross-sectional study was conducted with 223 breast cancer patients receiving peripherally inserted central catheter chemotherapy at two tertiary affiliated hospitals of China Medical University in Liaoning, China, from February 2021 to December 2022. Participants completed self-reported questionnaires to assess uncertainty, psychological resilience, self-care, and cancer-related fatigue. The collected data were subsequently analyzed using Pearson's correlation analysis, hierarchical regression analysis, and mediation analysis. RESULTS: Uncertainty exhibited a significant positive correlation with cancer-related fatigue (p < 0.01) and a negative correlation with psychological resilience (p < 0.01) and self-care (p < 0.01). Uncertainty was found to impact cancer-related fatigue through three pathways: psychological resilience mediated the relationship between uncertainty and cancer-related fatigue (mediating effect = 0.240, 95% confidence interval: 0.188 to 0.298, effect ratio = 53.22%); self-care also mediated this relationship (mediating effect = 0.080, 95% confidence interval: 0.044 to 0.121, effect ratio = 17.74%); furthermore, there was a significant joint mediating effect of psychological resilience and self-care on the association between uncertainty and cancer-related fatigue (mediating effect = 0.042, 95% confidence interval: 0.021 to 0.068, effect ratio o = 9.31%). CONCLUSION: The findings of this study revealed that uncertainty not only directly influenced cancer-related fatigue, but also operated through the mediating effect of psychological resilience, self-care, and sequential mediation of psychological resilience and self-care. Interventions tailored for breast cancer patients receiving peripherally inserted central catheter chemotherapy should target these factors to help alleviate uncertainty, enhance psychological resilience, and improve self-care practices, thereby ameliorating cancer-related fatigue.

Peripheral intravenous central catheter (PICC) is a common tool for intravenous infusion for children who need central venous access. Although it is safe for physicians and nurses to place, complications like infection, occlusion, phlebitis, and bleeding can occur. We report a 5-month-old infant who suffered respiratory failure caused by catheter malposition resulting in massive fluid infusion into the thoracic cavity. Point-of-care ultrasound (POCUS) was utilized to identify a massive pleural effusion that prompted urgent drainage. Complications related to PICC in pediatric patients are not common but difficult to immediately identify sometimes. Therefore, careful attention should be paid by physicians to identify and reduce the risk of complications associated with PICC. Thus, visual tools are strongly advised to enhance the safety of invasive procedures.

BACKGROUND: Peripherally inserted central catheters (PICCs) are common vascular access devices inserted for adults undergoing intravenous treatment in the community setting. Individuals with a PICC report challenges understanding information and adapting to the device both practically and psychologically at home. There is a lack of research investigating the supportive care needs of individuals with a PICC to inform nursing assessment and the provision of additional supports they may require to successfully adapt to life with a PICC. The aim of this study was to identify the supportive care needs of adults with cancer or infection living with a PICC at home. METHOD: Qualitative, semi-structured interviews were used to identify supportive care needs of adults living with a PICC at home. Participants were recruited from cancer and infectious diseases outpatient units. Two researchers independently analysed transcripts using content analysis. RESULTS: A total of 15 participants were interviewed (30-87 years old). There were 5 males and 10 females interviewed, 9 participants had a cancer diagnosis and most lived in a metropolitan area. Many participants lived with a partner/spouse at home and three participants had young children. Participants identified supportive care needs in the following eight categories (i (i) Adapting daily life (ii) Physical comfort (iii) Self-management (iv) Emotional impact (v) Information content (vi) Understanding information (vii) Healthcare resources and (viii) Social supports. CONCLUSIONS: Adults living with a PICC at home report a broad range of supportive care needs. In addition to practical and information needs, health consumers may also require support to accept living with a device inside their body and to assume responsibility for the PICC. These findings may provide nurses with a greater understanding of individual needs and guide the provision of appropriate supports.
RESUMO
Superior vena cava syndrome (SVCS) is caused by obstruction to the blood flow through this vein. Indwelling central venous devices, such as cardiac pacemakers and haemodialysis catheters have emerged as the most common benign aetiology of SVCS. SVCS is particularly severe in patients with end-stage renal disease who require continuous renal replacement therapy plus infusion therapy. The presence of SVCS results in a reduction of available venous access for affected patients. Therefore, venous access plays a crucial role in the management of these patients. The importance of dealing with vascular access (VA) in critical patients with these conditions cannot be overstated. This case describes an 81-year-old man with respiratory failure who had end-stage renal disease complicated with SVCS. Using ultrasound-guided puncture, we inserted a peripherally inserted central catheter (PICC) into the superficial femoral vein to meet his infusion requirements in intensive care. After successful placement, the catheter tip position was adjusted using imaging to position the tip relative to the haemodialysis catheter. Whenever patients with severe renal dysfunction are treated, central veins should be preserved. Safe PICC access is possible via the superficial femoral vein to protect the last central VA for rational use. This meets urgent needs for infusion and deserves promotion.
RESUMO
Right heart thrombus in transit or "free-floating right heart thrombus" is defined as thrombus(i) arising from the deep veins that embolises to the right atrium or right ventricle before reaching the pulmonary vasculature. It is almost always associated with pulmonary thromboembolism and is a medical emergency with reported mortality rates of over 40%. We present two cases of right heart thrombus in transit with pulmonary thromboembolism resulting from venous thrombosis associated with peripherally inserted central catheters that were managed with different approaches. The cases highlight that clinicians should have a low threshold to utilise imaging modalities such as computerised tomography and transthoracic echocardiography when there is an untoward change in physiological parameters among patients with peripherally inserted central catheters, particularly those with risk factors for peripherally inserted central catheter associated venous thrombosis. Furthermore, procedural optimisation surrounding peripherally inserted central catheters, such as insertion technique and choice of lumen size, is underscored.
RESUMO
A "bundle" is defined as a combination of evidence-based interventions that, if followed collectively and reliably, improve patient outcomes. The aim of this quasi-experimental study, conducted in a level-III NICU in Belgium, was to assess the impact of central line dressing and maintenance bundle implementation on the rate of catheter-related mechanical complications. We performed a quality improvement (QI) project. Prior to bundle implementation, neonatal PICC lines were secured by Steri-Strip® and occlusive dressing. We implemented a new PICC bundle consisting of the use of glue, sutureless device (Griplock®), and a transparent dressing to secure the catheter to the skin. We compared the rate of infections, mechanical complications, and dislocations before and after bundle implementation (periods 1 and 2, respectively). The use of glue resulted in a significantly decreased rate of central line-associated bloodstream infection (CLABSI) (p < 0.001), dislocations, and mechanical complications (p < 0.0001). During period 2, there was a significant increase for the average number of days the catheter stayed in place (p < 0.05). We did not observe catheter breakage or patient skin irritations attributable to the use of glue (not even in ELBW infants). CONCLUSION: The implementation of the new bundle to secure neonatal PICCs in our NICU was associated with a significant reduction in CLABSI and dislodgment rates, without glue-related complications. Active surveillance of CVC placement procedure, positioning, and management, as well as analysis of related complications is crucial for improving patient safety. Continuous implementation of up-to-date central line bundles based on best practice recommendations is a key for quality improvement in NICUs. WHAT IS KNOWN: ⢠Stable vascular access is crucial in the NICU. Neonatal PICC securement issues can have serious consequences and are associated with device failure. WHAT IS NEW: ⢠Catheter securement with tissue adhesive is safe and effective in reducing failure and complication rates in the neonatal population.

BACKGROUND: Cancer indeed represents a significant public health challenge, and unplanned extubation of peripherally inserted central catheter (PICC-UE) is a critical concern in patient safety. Identifying independent risk factors and implementing high-quality assessment tools for early detection in high-risk populations can play a crucial role in reducing the incidence of PICC-UE among patients with cancer. Precise prevention and treatment strategies are essential to improve patient outcomes and safety in clinical settings. OBJECTIVE: This study aims to identify the independent risk factors associated with PICC-UE in patients with cancer and to construct a predictive model tailored to this group, offering a theoretical framework for anticipating and preventing PICC-UE in these patients. METHODS: Prospective data were gathered from January to December 2022, encompassing patients with cancer with PICC at Xiangya Hospital, Central South University. Each patient underwent continuous monitoring until the catheter's removal. The patients were categorized into 2 groups: the UE group (n=3107) and the non-UE group (n=284). Independent risk factors were identified through univariate analysis, the least absolute shrinkage and selection operator (LASSO) algorithm, and multivariate analysis. Subsequently, the 3391 patients were classified into a train set and a test set in a 7:3 ratio. Utilizing the identified predictors, 3 predictive models were constructed using the logistic regression, support vector machine, and random forest algorithms. The ultimate model was selected based on the receiver operating characteristic (ROC) curve and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) synthesis analysis. To further validate the model, we gathered prospective data from 600 patients with cancer at the Affiliated Hospital of Qinghai University and Hainan Provincial People's Hospital from June to December 2022. We assessed the model's performance using the area under the curve of the ROC to evaluate differentiation, the calibration curve for calibration capability, and decision curve analysis (DCA) to gauge the model's clinical applicability. RESULTS: Independent risk factors for PICC-UE in patients with cancer were identified, including impaired physical mobility (odds ratio [OR] 2.775, 95% CI 1.951-3.946), diabetes (OR 1.754, 95% CI 1.134-2.712), surgical history (OR 1.734, 95% CI 1.313-2.290), elevated D-dimer concentration (OR 2.376, 95% CI 1.778-3.176), targeted therapy (OR 1.441, 95% CI 1.104-1.881), surgical treatment (OR 1.543, 95% CI 1.152-2.066), and more than 1 catheter puncture (OR 1.715, 95% CI 1.121-2.624). Protective factors were normal BMI (OR 0.449, 95% CI 0.342-0.590), polyurethane catheter material (OR 0.305, 95% CI 0.228-0.408), and valved catheter (OR 0.639, 95% CI 0.480-0.851). The TOPSIS synthesis analysis results showed that in the train set, the composite index (Ci) values were 0.00 for the logistic model, 0.82 for the support vector machine model, and 0.85 for the random forest model. In the test set, the Ci values were 0.00 for the logistic model, 1.00 for the support vector machine model, and 0.81 for the random forest model. The optimal model, constructed based on the support vector machine, was obtained and validated externally. The ROC curve, calibration curve, and DCA curve demonstrated that the model exhibited excellent accuracy, stability, generalizability, and clinical applicability. CONCLUSIONS: In summary, this study identified 10 independent risk factors for PICC-UE in patients with cancer. The predictive model developed using the support vector machine algorithm demonstrated excellent clinical applicability and was validated externally, providing valuable support for the early prediction of PICC-UE in patients with cancer.

BACKGROUND: The central line has been frequently used for drug and nutrition supply and regular blood sampling of patients with chronic diseases. However, this procedure is performed in a highly sensitive area and has several potential complications. Therefore, peripherally inserted central catheters (PICC), which have various advantages, are being extensively used. Although the number of PICC procedures is increasing, the anatomy for safe procedures has not yet been properly established. Therefore, we studied basic anatomical information for safe procedures. METHODS: We used 20 fixed cadavers (40 arms) donated to the Korea University College of Medicine. The mean age was 76.75 years (range, 48-94 years). After dissection of each arm, the distribution pattern of the basilic vein and close structures was recorded, and some important parameters based on bony landmarks were measured. In addition, the number of vein branches (axillary region) and basilic vein diameter were also checked. RESULTS: The mean length from the insertion site to the right atrium was 38.39 ± 2.63 cm (left) and 34.66 ± 3.60 cm (right), and the basilic vein diameter was 4.93 ± 1.18 mm (left) and 4.08 ± 1.49 mm (right). The data showed significant differences between the left and right arms (P < 0.05). The mean distance from the basilic vein to brachial artery was 8.29 ± 2.78 mm in men and 7.81 ± 2.78 mm in women, while the distance to the ulnar nerve was 5.41 ± 1.67 mm in men and 5.52 ± 2.06 mm in women. CONCLUSION: According to these results, the right arm has a shorter distance from the insertion site to the right atrium, and the left arm has a wider vein diameter, which is advantageous for the procedure. In addition, the ulnar nerve and brachial artery were located close to or behind the insertion site. Therefore, special attention is required during the procedure to avoid damaging these important structures.

Peripherally inserted central catheters are commonly used for intravascular access in low birth weight neonates. Here, we describe a case of transcatheter retrieval of an embolised peripherally inserted central catheter line in the right ventricle extending to the left pulmonary artery in a preterm very low birth weight baby. To the best of our knowledge, this is the first case where transcatheter retrieval of embolised peripherally inserted central catheter line has been done from the left pulmonary artery in such a very low birth weight preterm neonate. Although retrieval of foreign body is common in adults and older children, very few case reports have documented successful retrieval of embolised peripherally inserted central catheter line in very low birth weight neonates using interventional techniques. Most of the cases in literature reported retrieval of an indwelling umbilical venous catheter rather than a peripherally inserted central catheter line as in our case. Also, none of these cases had the embolised fragment retrieved from the left pulmonary artery. This approach was technically very challenging as we were taking care of a 5-day old preterm neonate born at 32 weeks of gestation having very low birth weight (1100 g) with features of clinical sepsis, coagulopathy, and embolised catheter fragment extending from right ventricle to left pulmonary artery. The procedure was uneventful without any complication and the catheter was retrieved successfully.

To explore the effect of music therapy on children with leukemia who have peripherally inserted central catheters (PICC).In this study, we divided 107 patients undergoing PICC into music group (47 cases) and control group (60 cases). The music group received music therapy during PICC, while the control group was given no complementary treatment. The total length of catheterization, the use of sedatives and the changes of pain level and emotion level before and after PICC placement were compared between two groups.Compared with the control group, the total PICC placement time of the music group was significantly shorter (35(30-40) vs. 60(60-60); Z = -8.307; p < 0.001), and the use of sedative medications was also significantly reduced (4.35% (n = 2) vs. 91.84% (n = 45); p < 0.001). Moreover, the pain of catheterization was significantly alleviated. The median difference of pain scores of the music group was significantly less (2(1-3) vs. 5(5-5); p < 0.001). The mood of patients was also improved. The median difference of emotional scores of the music group was significantly more (5(4.75-6) vs. 3(3-3); p < 0.001) than the control group.Music therapy is effective to use in PICC. It can shorten the treatment time, reduce the use of sedative medications, and improve the children's emotion and pain response significantly, which is worth clinical application.

Healthcare-acquired infections and multi-drug resistance in pathogens pose a major crisis for the healthcare industry. Novel antibiotics which are effective against resistant strains and unlikely to elicit strong resistance are sought after in these settings. We have previously developed synthetic mimics of ubiquitous antimicrobial peptides and have worked to apply a lead compound, CSA-131, to the crisis. We aimed to generate a system of CSA-131-containing coatings for medical devices that can be adjusted to match elution and compound load for various environments and establish their efficacy in preventing the growth of common pathogens in and around these devices. Peripherally inserted central catheter (PICC) lines were selected for our substrate in this work, and a polyurethane-based system was used to establish coatings for evaluation. Microbial challenges by methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Candida albicans were performed and SEM was used to evaluate coating structure and colonization. The results indicate that selected coatings show activity against selected planktonic pathogens that extend between 16 and 33 days, with similar periods of biofilm prevention.

Because the application of intracavitary electrocardiogram (IC-ECG)-guided peripherally inserted central catheter (PICC) in the treatment of neonates is controversial in terms of phlebitis reduction compared with traditional X-ray positioning technique, a systematical evaluation is needed on the impact of IC-ECG on this common complication following PICC. Literature retrieval was conducted on large databases including PubMed, Google Scholar, Cochrane library, and CNKI. Randomised controlled trials (RTCs) of intracavitary electrocardiogram-guided peripherally inserted central catheter tip placement in the treatment of neonates up to July 7, 2022, were collected. Then indicators of included studies were compared and analysed by two researchers. Meta-analysis was performed on the STATA 17.0 software. After excluding invalid trials, 11 out of 316 randomised controlled trials were included for further analysis. Meta-analysis results showed that compared with the control group, IC-ECG-guided PICC could decrease the incidence of phlebitis (I2 = 0.00%, P = 0.76, OR = 0.33, 95% CI 0.19-0.56) and that no significant difference was observed between preterm neonates and term neonates (P = 0.74). Meanwhile, total complications were decreased in neonates (I2 = 0.00%, P = 0.00 OR = 0.23, 95% CI 0.16-0.33). IC-ECG-guided PICC could also improve the accuracy of optimal tip location (I2 = 0.00%, P = 0.53, OR = 5.37, 95% CI 3.80-7.59). IC-ECG-guided PICC could achieve reduced phlebitis incidence and total complications in the treatment of neonates, as well as increased accuracy of optimal tip location, no matter if those neonates were preterm or not. This study was registered in inplasy.com with No. INPLASY202280012 (DOI: 10.37766/inplasy2022.8.0012).

Studies showed that integrating coating or valve into Peripherally Inserted Central (PICC) can prevent related complications. However, data regarding efficiency were controversial. Therefore, a systematic review was needed to analyse the effect of PICC materials and designs on reduction of PICC-related complications. We searched PubMed, Cochrane library, EMbase, grey literature and referent literature from inception to 5 August 2022. Randomized controlled trials (RCTs) and case-control study were included. Two authors extracted data independently, using a predesigned Excel form, and assessed the quality of included RCTs according to the Cochrane Handbook for Systematic Reviews (V5.1.0), case-control study was assessed by the Newcastle-Ottawa Scale. Data were analysed using Review Manager (v5.3.0). A total of 10 RCTs and one case-control study were included. Meta-analysis results showed that PICC designs reduce the incidence of obstruction, and at the critical value of PICC-associated bloodstream infection, but may have no effects on other complications. Based on the literature reviewed, we can only say PICC new materials did not reflect significant reduction on complications, what's more, the result needs more multicentre, large RCTs to support. We suggested clinicians combine descriptive research and cost-effect analysis to select appropriate PICC materials and designs for patients.
RESUMO
OBJECTIVES: Design the competency framework and an interview guide for patients with PICC line or midline. Develop a patient satisfaction evaluation questionnaire. METHODS: A multidisciplinary team has developed a reference system for the skills of patients with PICC line or midline. The skills are classified in three categories: knowledge, know-how and attitudes. An interview guide was written in order to transmit the priority skills, determined beforehand, to the patient. A second multidisciplinary team designed a questionnaire to evaluate patient satisfaction. RESULTS: The competency framework includes nine competencies: four, knowledge-based; three, know-how-based and two, attitude-based. Among these competencies, five were considered to be priorities. The interview guide is a tool that allows care professionals to transmit the priority skills to patients. The satisfaction questionnaire explores the information received by the patient, the passage through the interventional technical platform, the end of the management before the return home, and the overall satisfaction of the patients with the course of the device placement. Over a 6-month period, 276 patients responded with a high satisfaction rate. CONCLUSIONS: The PICC line or midline patient's competency framework has made it possible to list all the skills that patients should acquire. The interview guide serves as a support for the care teams in the patient education process. This work could be used by other establishments to develop the educational process around these vascular access devices.

OBJECTIVE: To observe the changes of F waves on electrocardiograms (ECGs) in patients with persistent atrial fibrillation during the insertion of a peripherally inserted central catheter (PICC), and to analyze the application effect of the ECG method (through F wave changes) for guiding PICC tip positioning. METHODS: Seventy-two patients who met the inclusion criteria and needed a PICC catheter were selected as the research subjects. We observed waveforms in the ECGs when the tip of the catheter reached a predetermined position. The chest X-ray results were used as the gold standard to calculate the sensitivity and specificity, and judge the safety and accuracy of ECG-guided PICC tip positioning in patients with atrial fibrillation. RESULTS: Of the 72 patients, there was no significant difference between the ECG method and chest X-ray results (χ2 = 0.2, p > 0.05). Sixty-one patients had F wave changes on ECG and 10 had no obvious changes (X-ray results confirmed that five patients had a tip position that was too shallow, two had ectopic tip positions, and three were located in the correct place). The sensitivity of the method was 95.7% and the specificity was 80%. CONCLUSION: As the ECG baselines of patients with persistent atrial fibrillation were difficult to judge and the F wave was irregular, we found that the F wave was significantly higher than before catheter insertion and fell back while withdrawing the catheter, so the catheter should be fed until the F wave significantly increased as the correct position of the catheter tip.

OBJECTIVE: To explore the clinical significance of intracavitary electrocardiogram positioning technology in preventing catheter ectopic position during peripherally inserted central catheter (PICC) catheterization in children with tumors. METHODS: A retrospective analysis of the clinical data of 62 children who required PICC catheterization was performed. The intracavitary electrocardiogram (ECG) positioning technology was used during the tube placement of the child patients. After the tube was successfully placed, the chest radiograph was taken. The ECG positioning result was compared with the chest radiograph positioning result after the tube was inserted, and the sensitivity and specificity of the ECG positioning were calculated. RESULTS: The intracavitary electrocardiogram results of 62 children with PICC catheters showed that 56 cases (90.32%) had characteristic P waves, and six cases (9.68%) had no characteristic P waves. The chest radiographs of 56 children with characteristic P wave showed that 33 cases (58.93%) of the catheter tip position was appropriate, 22 cases (39.29%) of the catheter tip was too deep, and 1 case was in a non-superior vena cava; six cases of chest radiographs of children with no characteristic P wave showed: one case was too deep at T8 level, one case was too shallow at T4 level, four cases were at non-superior vena cava, one case was contralateral internal jugular vein, two cases in the contralateral brachiocephalic vein, and one case was the contralateral subclavian vein. CONCLUSION: Intracavitary ECG positioning assisted catheter placement in infants can effectively improve the accuracy of catheter tip position.

PURPOSE: To explore the application of ECG-guided localization technology in PICC catheterization and the clinical significance of different maps of intracavitary ECG in PICC tip localization. METHODS: In the process of catheter placement under the guidance of ultrasound, the technique of intracavitary ECG location was used. The length of the catheter was measured on the body's surface. The amplitude of the P-wave and the QRS-wave groups of electrocardiograms before and during catheter placement was recorded. Nine hundred sixty-one patients who underwent X-ray chest film examination after catheterization were imaged on the chest film at the tip of the catheter. RESULTS: Eight hundred four cases had a characteristic P wave, 83.66%, of which, 331 cases (50% < P/R ≤80%) had 99.09%; 425 cases (80% < P/R ≤100%) had 99.29%; 48 cases (P/R >100%) had 100%. One hundred eighteen cases of non-specific P wave accounted for 12.28% and 79.66% of chest radiographs, of which 72 cases of P/R <50% were 100%; 46 cases of unchanged P wave were 47.83%; 34 cases of special cases accounted for 3.54% and 55.88% of chest radiographs; five cases of interference wave accounted for 0.25%, and the chest radiographs were self-control. The in-place rate of the body contrast catheter was 80%. CONCLUSIONS: The accuracy of the ECG characteristic map in guiding the location of the PICC tip is higher than that of the non-characteristic P wave, and it has more clinical significance in locating the best position of the PICC tip.

BACKGROUND: Although peripherally inserted central catheters (PICCs) have been widely used, they have not been frequently used in anesthesia practice. The central venous pressure measured via PICCs are reportedly as accurate as that measured via central venous catheters (CVCs), but the findings concerning rapid infusion are unclear. This study examined whether or not pressure-resistant PICCs could be used for rapid fluid infusion. METHODS: The in-line pressure was measured in similar-sized double-lumen catheters-4-Fr PICC (55, 45 and 35 cm) and 17-G CVC (20 and 13 cm)-at flow rates of saline decided using a roller pump system. We also examined the flow rate at an in-line pressure of 300 mmHg, which is the critical pressure at which hemolysis is considered to occur during blood transfusion. RESULTS: The pressure-resistant PICCs obtained a high flow rate similar to that of CVCs, but the in-line pressures increased in proportion to the flow rate and catheter length. Flow rates at an intra-circuit pressure of 300 mmHg were not significantly different between the 45-cm PICC and 20-cm CVC. CONCLUSION: Pressure-resistant PICCs can be used for rapid fluid infusion.

OBJECTIVE: This study aimed to analyze the application value of intracavitary electrocardiogram (ECG) classification in peripherally inserted central catheter (PICC) tip localization in patients with cancer. METHODS: Using a self-control study method, 325 patients with cancer underwent intracavitary ECGs to position the tip of a PICC catheter. The P wave, QRS wave amplitude, and waveform changes of each intracavitary ECG were recorded. Chest X-ray examination was performed after the catheterization to compare the results of different intracavity ECG maps with the results of the chest X-ray. RESULTS: The intracavitary ECG positioning maps of the 325 patients were divided into four categories: (1) increased P wave (293 cases), accounting for 90.15% (293/325) of all cases; compared with the positioning results of the chest X-rays, the placement rate was 98.98% (290/293); (2) negative deepening of the P wave (1 case), accounting for 0.31% (1/325) of all cases and with a placement rate of 100% (1/1); (3) no change in P wave (19 cases), accounting for 5.85% (19/325) of all cases and with a placement rate of 42.11% (8/19); (4) atrial fibrillation/atrial flutter (12 cases), accounting for 3.69% (12/325) of all cases and with a placement rate of 58.33% (7/12). The four types of intracavitary ECG positioning maps had statistically significant differences (χ2 = 133.924, P = 0.000). CONCLUSION: There are four types of intracavitary ECG localization maps: increased P wave, negative deepening of the P wave, no change in P wave, and atrial fibrillation/atrial flutter. The increased P wave pattern had the highest occurrence probability and high positioning accuracy. It therefore has strong clinical application value for PICC tip localization in patients with cancer.
