Central line associated bloodstream infection (CLABSI) is the most severe complication of indwelling intravascular catheters and one of the most common causes of intensive care unit (ICU)- or hospital-acquired infections. Once CLABSI occurs, it significantly increases the risk of mortality, long of hospital stay, and healthcare economic burden. In recent years, multiple large-scale clinical studies on the diagnosis, treatment, and prevention of CLABSI have been completed, providing evidence-based medical support for related practices. Additionally, evolving global trends in antibiotic resistance epidemiology and the development of novel antimicrobial agents necessitate adjustments in clinical management strategies. Based on these developments, the Chinese Society of Critical Care Medicine has updated and revised the Guideline on the Prevention and Treatment of Intravascular Catheter-Related Infections (2007). This guideline was developed following the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system for evidence quality assessment. Guided by clinical questions, the working group initiated the process by defining key clinical issues, conducting literature searches, screening studies, performing meta-analyses, and synthesizing evidence-based findings to draft preliminary recommendations. These recommendations underwent iterative revisions through expert panel reviews, remote and in-person meetings, and two rounds of voting by the Standing Committee of the Chinese Society of Critical Care Medicine before finalization. The guideline comprises 52 recommendations, focusing on adult patients with central venous catheters in ICU. Key areas addressed include: selection of catheter insertion sites and techniques, catheter type and design, catheter management, prevention, diagnosis, and treatment of CLABSI. The guideline aims to provide ICU healthcare professionals with best practices for central line management, ensuring standardized clinical protocols for adult CLABSI.

OBJECTIVE: To investigate the differences in indwelling duration, clinical scenarios, and complications between the modified midline catheter (MMC) and the central venous catheter (CVC) in the treatment of patients in the medical intensive care unit (ICU) and the risk factors for complications based on real-world data. METHODS: A retrospective cohort study was conducted. The adult patients admitted to the medical ICU of the Third Xiangya Hospital of Central South University and had undergone placement of either a MMC or a CVC between January 1, 2023, and July 31, 2024, were consecutively enrolled by querying the hospital's electronic medical record system. Based on the type of catheter inserted, the patients were divided into the MMC group and the CVC group. The two groups were compared regarding the selection of catheters in the context of different underlying diseases, the actual clinical application after catheterization, catheter-related complications, the international normalized ratio (INR) and platelet count (PLT) during puncture and catheterization, the length of ICU stay, total length of hospital stay, catheter indwelling duration, and mortality during hospitalization. Multivariate Logistic regression analysis was employed to identify independent risk factors for catheter removal. RESULTS: Among the 274 patients, 52 received a MMC and 222 received a CVC. The utilization rate of MMC was significantly higher than that of CVC in patients with acute respiratory distress syndrome (ARDS), cardiovascular disease, and cancer [ARDS: 92.3% (48/52) vs. 70.3% (156/222), cardiovascular disease: 84.6% (44/52) vs. 54.5% (121/222), cancer: 30.8% (16/52) vs. 17.1% (38/222), all P < 0.05]. However, the use of MMC was significantly lower than CVC when vasoactive drug infusion was required [57.7% (30/52) vs. 79.7% (177/222), P < 0.05]. A significantly higher proportion of patients in the MMC group had a catheter indwelling time ≥ 12 days as compared with the CVC group [32.7% (17/52) vs. 13.5% (30/222), P < 0.05]. There were no statistically significant differences in other underlying diseases, venous access usage, INR and PLT during puncture and catheterization, length of ICU stay, total length of hospital stay, and in-hospital mortality of patients between the two groups. Regarding catheter-related complications, although the incidence of partial or complete catheter removal in the MMC group was significantly higher than that in the CVC group [36.5% (19/52) vs. 5.4% (12/222), P < 0.05], the incidence of puncture site fluid leakage, puncture site skin allergy, and deep vein thrombosis were significantly lower than those in the CVC group [puncture site fluid leakage: 1.9% (1/52) vs. 22.1% (49/222), puncture site skin allergy: 0% (0/52) vs. 20.7% (46/222), deep vein thrombosis: 3.8% (2/52) vs. 16.7% (37/222), all P < 0.05]. Furthermore, the proportion of patients experiencing three or more types of complications in the MMC group was significantly lower than that in the CVC group [5.8% (3/52) vs. 17.6% (39/222), P < 0.05]. Multivariate Logistic regression analysis of risk factors for catheter removal identified the use of a MMC [odds ratio (OR) = 8.518, 95% confidence interval (95%CI) was 3.710-19.560, P < 0.001] and a catheter indwelling time ≥ 12 days (OR = 3.133, 95%CI was 1.297-7.567, P = 0.011) as independent risk factors. CONCLUSIONS MMC was more frequently used in patients with ARDS, cardiovascular disease, and cancer, whereas CVC was primarily employed for vasoactive drug infusion. The use of MMC and a longer indwelling time were identified as independent risk factors for catheter removal. Despite a higher removal rate, the overall incidence of complications was significantly lower with MMC than with CVC. These findings suggest that MMC could serve as a routine alternative to CVC in most of clinical scenarios, provided that measures are implemented to prevent removal.

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 compare the dwelling time and complications of low lying umbilical venous catheterization (UVC) in preterm infants with that of central UVC. Methods: This was a prospective cohort study. A total of 3 020 preterm infants from 44 neonatal intensive care units (NICU) who had UVC inserted from October 2019 to August 2021 were enrolled. Demographic and general baseline data, dwelling time of UVC and reasons for removal, complications and their occurrence time were collected. According to the position of the catheter tip, the preterm infants were divided into low lying UVC group (insertion depth of 3-5 cm) and central UVC group (the catheter tip was close to the entrance of right atrium, or at the 8^th-9^th thoracic vertebra level). The Mann-Whitney U test was used to compare the dwelling time and incidence of complications (cases/1 000 catheter days), and the independent t test and Chi-square test were used to compare the characteristics between the 2 groups. The receiver operating characteristic (ROC) curve was used to analyze the optimal cut-off value of UVC dwelling time. Results: Among the included 3 020 preterm infants, 1 624 (53.8%) were males, the gestational age was 29.9 (28.4, 31.6) weeks, the birth weight was (1 264±301) g, and 2 172 (71.9%) premature babies had central UVC. There were no significant differences in the proportion of males, the gestational age and the birth weight of neonates between the 2 groups (all P>0.05). There were also no significant differences in the rate of maternal history, PPROM>18 hours, chorioamnionitis, antenatal antibacterial angents exposure and antibacterial angents usage through UVC (all P>0.05). The dwelling time of central UVC was longer than that of low lying UVC (7 (6, 10) vs. 4 (3, 7) days, U=23.42, P<0.001). The complication incidence of central and low lying UVC were 20.0 and 70.8 cases/1 000 catheter days, respectively. The top 3 complications of central UVC were occlusion, catheter tip migration, and CLABSI (9.3, 3.5, 3.0 cases/1 000 catheter days). The top 3 complications of low lying UVC were catheter occlusion, CLABSI, and catheter tip migration (45.8, 6.3, 5.4 cases/1 000 catheter days). The ROC curve of UVC dwelling time and complications showed that the cut-off values ​​of central UVC and low lying UVC were 6.5 and 4.5 days, respectively. The 2 groups both showed a trend of increases in the 3 complications with the prolonged dwelling time. Cox regression analysis showed that the overall difference in the proportion of occlusion between the central UVC and low lying UVC groups was statistically significant (χ²=30.18, P=0.024). There were both no significant differences in catheter tip migration and CLABSI (both P>0.05). Conclusions: The most common UVC complication in preterm infants is occlusion. It is not recommended to keep a low lying UVC for longer than 4.5 days. During the whole dwelling period, a close monitoring for UVC complications is required.

Deep venipuncture catheterization is a routine and basic operation in the treatment of critically ill patients, and it is the most effective way to quickly correct the shock. Clinical B-ultrasound guided deep vein catheters can improve the success rate of puncture, but in the process of operation, the short axis needs to be replaced by the long axis. In the replacement process, the stability of the novice is insufficient, the positioning is difficult, and the operation time is too long. If only short axis puncture is used, it is impossible to know whether the current position of the puncture needle, and the puncture may be too deep and stray into the artery. The accuracy of the 45 degree angle of the injection point requires a very experienced operator. In view of the above shortcomings, doctors in the department of critical care medicine of Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine designed a B-ultrasound puncture equipment, which has obtained the National Invention Patent of China (ZL 2016 1 0571557.X). The device is composed of B-ultrasound probe fixing frame, sliding scale plate, simulation slide rule, puncture needle, sliding device. By sliding device the angle of the pinhole channel, it is conducive to the accurate positioning of the puncture target, optimizing the operation procedure, improving the puncture speed and accuracy, effectively reducing the occurrence of puncture complications, ensuring patient safety, reducing unnecessary waste of human and material resources. It can reduce the workload of medical staff and is worthy of clinical practice.

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 summarize the surgical experience of totally implantable venous access port in children with malignant tumors, and to explore the coping methods of surgical complications. METHODS: The clinical data of 165 children with malignant tumors implanted in totally implantable venous access port in Department of Pediatric Surgery, Peking University First Hospital from January 2017 to December 2019 were retrospectively analyzed. The operation process, complications and treatment of complications were observed and counted. RESULTS: The children in this group were divided into external ju-gular vein incision group (n=27) and internal jugular vein puncture group (n=138) according to different surgical methods, and the latter was divided into ultrasound guided puncture group (n=95) and blind puncture group (n=43). No puncture complications occurred in the external jugular vein incision group, and the average time for successful catheterization and the number of times for catheter to enter the superior vena cava were more than those in the internal jugular vein puncture group [(9.26±1.85) min vs. (5.76±1.56) min, (1.93±0.87) times vs. 1 time], with statistical significance. The average time of successful catheterization, the success rate of one puncture, the average number of punctures and the incidence of puncture complications in the ultrasound guided right internal jugular vein puncture group were better than those in the blind puncture group [(5.36±1.12) min vs. (6.67±1.99) min, 93.68% (89/95) vs. 74.42% (32/43), (1.06±0.24) times vs. (1.29±0.55) times, 2.11% (2/95) vs. 11.63% (5/43)], with statistically significant differences. The total incidence of complications in this study was 12.12% (20/165). Pneumothorax occurred in 1 case, artery puncture by mistake in 1 case, local hematoma in 5 cases, venous access port related infection in 4 cases (venous access port local infection in 2 cases, catheter related blood flow infection in 2 cases), subcutaneous tissue thinning on the surface of port seat in 2 cases, port seat overturning in 1 case, poor transfusion in 4 cases (catheter discount in 1 case, catheter blockage in 3 cases), and foreign bodies gathered around the subcutaneous pipeline in 2 cases. There were no complications, such as catheter rupture, detachment and catheter clamping syndrome. CONCLUSION Totally implantable venous access port can provide safe and effective infusion channels for children with malignant tumors. Right external jugular vein incision and ultrasound-guided right internal jugular vein puncture are reliable surgical methods for children's totally implantable venous access port implantation. Surgeons should fully understand the complications of the venous access port, take measures to reduce the occurrence of complications, and properly handle the complications that have occurred.

OBJECTIVES: To study the efficiency of electrocardiogram (ECG) monitor for positioning the catheter tip in the placement of peripherally inserted central venous catheterization (PICC) via lower extremity veins in neonates. METHODS: A total of 120 neonates who were admitted to the neonatal intensive care unit from January 2020 to January 2022 and received PICC via lower extremity veins were enrolled and divided into a control group and an observation group using a random number table (n=60 each). The neonates in the control group were given body surface measurement and postoperative chest X-ray localization, and those in the observation group were given body surface measurement, ECG-guided positioning, and postoperative chest X-ray localization. The two groups were compared in terms of general information, one-time success rate of PICC placement, and time spent on PICC placement, and the efficiency of ECG-guided positioning was evaluated. RESULTS: Compared with the control group, the observation group had a higher one-time success rate of PICC placement (92% vs 75%; P<0.05) and a shorter time spent on PICC placement [(26.5±3.0) min vs (31.8±2.8) min; P<0.05]. ECG-guided positioning had a sensitivity of 90.9% and a specificity of 100% in the PICC placement via lower extremity veins in neonates. CONCLUSIONS ECG monitor helps to determine the position of catheter tip in the PICC placement via lower extremity veins in neonates and can improve the one-time success rate of PICC placement and reduce the time spent on PICC placement, with a good positioning efficiency.
