INTRODUCTION: Totally implantable venous access devices (TIVADs) or ports are increasingly used in oncology settings to provide long-term, easy venous access. This study reports our experience and results with 1180 cases in Singapore. METHOD: Data from January 2019 to January 2022, obtained from a hospital-approved secure database application called the Research Electronic Data Capture registry, were reviewed and analysed retrospectively. RESULTS: A total of 1180 patients underwent TIVAD implantation with a 100% technical success rate. The mean age of the cohort was 61.9 years. The mean dwell duration was 342 days (standard deviation [SD] 223; range 3-1911). By 1 February 2022, 83% of patients were still using the TIVAD, 13.6 % underwent removal after completion of treatment, 2.1% were removed due to infection, 0.6% due to malfunction, 0.6% due to port extrusion and 0.1% at patient's request. The right internal jugular vein (IJV) was the most commonly accessed site (83.6%), followed by the left IJV (15.6%). The early post-procedure complications were pain (24.7%), bruising (9.2%), swelling (3.6%), bleeding (0.5%), fever (0.4%), itchiness (0.2%) and allergic dermatitis (0.1%). The delayed post-procedure complications were TIVAD site cellulitis (3.80%); discharge (1.10%); skin erosion with device extrusion (0.60%); malpositioned catheter (0.33%), which was successfully repositioned, catheter-related bloodstream infections (0.25%); migration of TIVAD leading to catheter dislodgement (0.25%); venous thrombosis (0.25%); fibrin sheath formation requiring stripping (0.10%) and TIVAD chamber inversion (0.10%). CONCLUSION TIVAD implantation via the jugular vein under radiological guidance provides a safe, reliable and convenient means of long-term venous access in oncology patients. By sharing our experience and acceptable outcomes from a large oncology cohort, we aim to increase the awareness and adoption of TIVAD usage in oncology patients, especially in Asia.

OBJECTIVE: To provide evidence for further reducing the incidence of central line-associated bloodstream infection (CLABSI) according to investigation of the prevention and control of CLABSI in intensive care unit (ICU) in Shandong Province. METHODS: The questionnaire was developed by experts from Shandong Critical Care Medical Quality Control Center, combining domestic and foreign guidelines, consensus and research. A convenient sampling method was used to recruit survey subjects online from October 11 to 31, 2023 in the province to investigate the management status of central venous catheter (CVC) in ICU units of secondary and above hospitals. RESULTS: A total of 201 valid data were collected, involving 186 hospitals in the province, with a total of 201 ICU units, mainly comprehensive ICU (91%). The beds in ICU units were mainly single rooms (89%) and triple rooms (79%), and the ratio of doctors to total beds was 0.54 : 1. The training on the knowledge and operation of intravascular catheter-associated bloodstream infection in each ICU unit was mainly irregular (49%), and 96% of the catheter operators were authorized by the hospital. In terms of CVC selection, 89% of ICU units used dual-chamber CVC, and 86% of ICU units used catheters without antibiotic coating. When selecting the placement site, for conventional CVC catheterization, 65% preferred subclavian vein. Femoral vein was preferred in 87% of ICU units undergoing continuous renal replacement therapy. 95% of ICU units had established standardized operation procedure (SOP) for CVC placement. 86% of ICU units were capable of ultrasound positioning or guided puncture at the time of catheterization. During catheterization, 88% of ICU units met the sterile dress code. Before and after catheterzation, 81% and 77% of ICU units standardized hand hygiene. Only 31% of ICU units were covered from head to toe by aseptic wipes. For the choice of skin disinfectant, the majority of ICU units (72%) only used iodophor. After tube placement, 54% of ICU units chose sterile transparent dressing and 25% chose sterile gauze dressing. 98% of ICU units were sutured to secure the catheter. Regarding catheter replacement and removal, 45% of ICU units could not be removed or replaced within 2 days in emergency situations where the principle of sterility was not guaranteed. When CLABSI was suspected, 55% of ICU units were able to obtain the catheter tip, transcatheter blood culture, and contralateral peripheral vein blood culture at the same time. For CVC replacement frequency, most ICU units (75%) would not be replaced regularly, and some ICU units would be replaced regularly, but the frequency of replacement was different. For CLABSI prevention and control, 82% of ICU units developed a verification form or supervision form. When analyzing the sources of CLABSI data, most of them were filled in by themselves (60%). As for the frequency of data analysis, 57% were once a month. CONCLUSIONS All ICU units in Shandong Province are standardized in terms of the authorization of operators, the formulation of SOP, the formulation and implementation of verification form and supervision form, ultrasound-guided puncture, and hand hygiene before and after catheterization. However, there are still deficiencies in the training on knowledge and operation of intravascular catheter-associated bloodstream infections, maximum aseptic coverage, catheter replacement and removal, and the reporting sources of CLABSI data, which need to be strengthened in the follow-up work. At present, the selection of CVC, the selection of catheterization site, the selection of skin disinfectant and the selection of dressings after catheterization still need further research.

It is difficult to insert long-term dialysis catheters after severe stenosis or occlusion of the internal jugular vein and innominate vein. We used REcanalisation and balloon-oriented puncture for Re-insertion of dialysis catheter in nonpatent central veins (REBORN) in seven patients with severe central venous lesions, and all patients were inserted with long-term dialysis catheters successfully. None had severe complications such as pneumothorax, hemothorax, or pulmonary embolism during operation. All catheters functioned well after postoperative follow-up of 2 months. REBORN provides a novel approach to establish difficult dialysis pathways.

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

The female infant in this case study was admitted to the hospital 4 hours after birth due to preterm birth and respiratory distress. On the third day after birth, peripherally inserted central venous catheter (PICC) catheterization was performed. On day 42, thrombus was found at the entrance of the right atrium from the inferior vena cava during a cardiac ultrasound, and it was considered to be related to PICC placement. Low-molecular-weight heparin and urokinase were given. After two weeks of treatment, ultrasonic monitoring showed thrombus shrinkage. No bleeding or pulmonary embolism occurred during the treatment. The patient discharged after improvement. This article mainly introduces a multidisciplinary team approach to diagnosis and treatment of PICC-related thrombosis in neonates.

Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.

OBJECTIVES: To study the features of catheter-related bloodstream infection (CRBSI) or central line-associated bloodstream infection (CLABSI) after peripherally inserted central catheterization (PICC) in neonates admitted to the neonatal intensive care unit (NICU) and the risk factors for CRBSI or CLABSI. METHODS: A retrospective analysis was performed on the medical data of the neonates who were treated and required PICC in the NICU of the Children's Hospital, Zhejiang University School of Medicine from June 1, 2018 to May 1, 2020. The catheterization-related data were collected, including placement time, insertion site, removal time, and antimicrobial lock of PICC. The multivariate logistic regression model was used to investigate the risk factors for CRBSI or CLABSI in the neonates. RESULTS: A total of 446 neonates were enrolled, with a mean gestational age of (30.8±4.0) weeks, a mean birth weight of (1 580±810) g, a median age of 9 days, and a median duration of PICC of 18 days. The incidence rates of CLABSI and CRBSI were 5.6 and 1.46 per 1 000 catheter days, respectively. Common pathogens for CLABSI caused by PICC included Staphylococcus epidermidis (n=19) and Klebsiella pneumoniae (n=11), and those for CRBSI caused by PICC included Klebsiella pneumoniae (n=6). The risk of CLABSI caused by PICC increased significantly with prolonged durations of PICC and antibiotic use, and the PICC-related infection probability at head and neck was significantly lower than that in the upper and low limbs (P<0.05), while the above conditions were more obvious in neonates with a birth weight of <1 500 g. The risk of CRBSI caused by PICC decreased with the increase in gestational age (P<0.05). CONCLUSIONS CRBSI and CLABSI remain serious issues in NICU nosocomial infection. The identification of the risk factors for CRBSI and CLABSI provides a basis for improving the quality of clinical care and management.

Objective: To investigate the safety and efficacy of dual guiding catheter kissing technique (DCK) in the treatment of stent partly dislodgement in coronary artery. Methods: The study retrospectively involved 6 hospitalized patients with coronary artery stent partly dislodgement during PCI at The First Affiliated Hospital of Zhengzhou University from February 2016 to June 2019, DCK was used in these patients. We observe the success rate of stent retrieval, success rate of PCI, incidence of complications and major adverse cardiovascular events in 1 year follow up. Results: 6 patients were involved, of which 3 are male, ages range 49 to 68 years old, 4 patients are diagnosed with unstable angina, the other two are stable angina. All the partially disloged stents in the 6 patients were successfully removed from coronary artery. Except for 1 patient who refused coronary artery stenting again, the other 5 patients were successfully implanted coronary artery stenting. No serious complications occurred, no patients died and no major adverse cardiovascular events happened during 1 year follow up. Conclusions: DCK is safe and effective to remove partially dislodged stent in coronary artery.

Peripherally inserted central catheter (PICC) has been widely used in the neonatal intensive care unit (NICU) in recent years, but there are potential risks for complications related to PICC. Based on the current evidence in China and overseas, the operation and management guidelines for PICC in neonates were developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) in order to help the NICU staff to regulate the operation and management of PICC.
