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.

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.

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.

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.

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.

The best tip position of PICC is located in the inferior 1/3 of superior vena cava to the junction between superior vena cava and right atrium. Ensuring the best tip position of PICC is very important for the treatment of patients. In this paper, the applications of X-ray positioning, electrocardiograph, ultrasound, electrocardiograph Doppler ultrasound guidance, and electromagnetic navigation system in PICC tip positioning technology are reviewed. The future development of PICC tip positioning technology is prospected.

Cerebral air embolism (CAE) is a rare complication of various medical procedures. It manifests with symptoms similar to those of typical acute cerebral infarction, however the treatment is quite different. We present a case of arterial CAE that was associated with a disconnected central venous catheter and appeared as punctate dark signal intensities with aliasing artifacts on the susceptibility-weighted filtered phase magnetic resonance image. The susceptibility-weighted filtered phase image can be helpful for diagnosing CAE and the magnetic resonance imaging reflects the pathophysiology of CAE.

Newborn infants, including premature infants, are high-risk patients susceptible to various microorganisms. Catheter-related bloodstream infections are the most common type of nosocomial infections in this population. Regular education and training of medical staffs are most important as a preventive strategy for central line-associated bloodstream infections (CLABSIs). Bundle approaches and the use of checklists during the insertion and maintenance of central catheters are effective measures to reduce the incidence of CLABSIs. Chlorhexidine, commonly used as a skin disinfectant before catheter insertion and dressing replacement, is not approved for infants <2 months of age, but is usually used in many neonatal intensive care units due to the lack of alternatives. Chlorhexidine-impregnated dressing and bathing, recommended for adults, cannot be applied to newborns. Appropriate replacement intervals for dressing and administration sets are similar to those recommended for adults. Umbilical catheters should not be used longer than 5 days for the umbilical arterial catheter and 14 days for the umbilical venous catheter. It is most important to regularly educate, train and give feedback to the medical staffs about the various preventive measures required at each stage from before insertion to removal of the catheter. Continuous efforts are needed to develop effective and safe infection control strategies for neonates and young infants.
