Atypical use of PICC as centrally inserted central catheter in infants and neonates: Report of a 10-year experience

PICC tip dislodgement causing massive pleural effusion and atelectasis with acute respiratory failure: a case report

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.

Central Lines and Their Complications in Neonates: A Case Report and Literature Review

Central lines are essential devices in NICUs, used primarily in preterm neonates and critically ill term neonates. They are typically divided into non-tunnelled, tunnelled and totally implanted. In light of the increasing use of central lines in the NICU setting, monitoring of the risk factors associated with complications has to be an important part of neonatal care quality management. Presented here is a case of a preterm neonate with cardiac tamponade caused by UVC tip migration. Among complications of central lines are CLABSI, with an incidence of 3 to 21 per 1000 catheter days, and portal vein thrombosis, which is common but probably under-recognised, whereas other mechanical complications such as pericardial and pleural effusions are rare, with an incidence of less than 1%. Complications can cause injury to the neonates, as well as increase the costs of health services because of increases in the length of stay in the NICU. It is recommended that the catheter tip location is confirmed either by X-ray or ultrasonography. In order to minimise the risk of CLABSI, the use of bundles is recommended. Certain recommendations need to be followed when using different types of catheters. Future research is aimed at novel ways of central line securement to minimise mechanical complications and the use of antimicrobial catheters to reduce the rate of CLABSI.

Performance of tunnelled, non-cuffed central venous catheters in infants: A scoping review

AIM

To summarise and critique existing knowledge and evidence relating to the utility, and post-insertion complications surrounding tunnelled non-cuffed central venous catheters (tncCVCs) in infants.

METHODS

A scoping review of original research studies reporting the use of, and post-insertion complications associated with, tncCVCs in infants was completed. MeSH terms were used to formulate a systematic search, and data were extracted using a customised data extraction form. Data were analysed descriptively across key themes based on the research questions. Study quality was evaluated using the Mixed Methods Appraisal Tool.

RESULTS

The systematic search generated 3994 studies, of which 9 studies met final inclusion criteria. Studies included 644 tncCVCs in infants based in the USA, Europe and Australia. Most studies were retrospective cohort studies. The most common vein of insertion, where individually specified, was the internal jugular (n = 177). Tunnel length, where reported, was 2.5-5 cm. Infection rates were most commonly reported (eight studies), with results ranging from 0 to 12.8%, and device dislodgements of up to 20% reported. Participant follow-up and definition of complications varied greatly between studies. Study quality across all papers was sound.

CONCLUSIONS

This review has identified only a small number of studies, with small participant numbers, reporting the performance of tncCVCs in infants. Definitions of complications measured varied significantly between studies, and vastly different patient follow-up protocols were reported. Further larger-scale studies on the performance of tncCVC, employing internationally recognised reporting standards is warranted to ensure clinicians can make informed choices for medication and infusion delivery.

Clinical Characteristics of Venous Thrombosis Associated with Peripherally Inserted Central Venous Catheter in Premature Infants

Background: This study aimed to analyze clinical characteristics and risk factors for peripherally inserted central catheter (PICC) placement in premature infants. Materials: This study included seven premature infants who were hospitalized in the neonatal intensive care unit (NICU) of Peking University Third Hospital from 1 January 2014–30 June 2021, and suffered PICC-related venous thrombosis. The control group included premature infants (n = 56) matched (1:8) by the following: Did not experience venous thrombosis; born with a similar gestational age (±2 w), birth weight (±200 g); and received PICC catheterization in the same period (±4 w). Clinical neonatal data were collected through the hospital electronic medical record system and analyzed using SPSS version 23. Results: The incidence of PICC-related thrombus was 0.23% (7/3043. Univariate analysis revealed that, compared to the non-thrombotic group, mothers in the thrombosis group had autoimmune diseases (χ² = 9.844, p = 0.030) and used anticoagulative drugs during pregnancy (χ² = 8.036, p = 0.025). The corrected gestational age when PICC-related thrombosis occurred in the thrombosis group was 32 + 6 (30 + 1, 34 + 1) weeks. The average time from catheter placement to thrombosis was 5 (1, 12) days. Among infants, 85.7% (6/7) experienced deep vein thrombosis, of which four were in the lower extremity veins; three occurred within 2 days after central venous catheter extubation, and four occurred during central venous catheter indwelling. The clinical manifestations of thrombosis include skin edema, color changes, and skin temperature changes in the affected limbs. The seven neonates had normal coagulation at the time of thrombus diagnosis, but D-dimers significantly increased 1–2 days after thrombosis, returning to normal 5–8 days after thrombus. The thrombus persisted for 4.5 (3, 8) days. All seven neonates were treated with low molecular weight heparin calcium anticoagulation for 10 (3, 17) days and recovered completely. Conclusions: PICC-related thrombosis occurred within 1 week after catheter placement, and thrombosis more likely happened in infants whose mothers had autoimmune disease. When this high-risk factor exists and the patient has been intubated for 1 week and has sudden swelling in the intubated limb, venous ultrasound should be performed immediately to diagnose, and treatment should be provided in a timely manner to reduce adverse events.
