Diagnostic accuracy among trainees to safely confirm peripherally inserted central catheter (PICC) placement using bedside ultrasound

Effect of intracavitary electrocardiographic localization on the success rate and complications of PICC in infants

BACKGROUND

Peripherally inserted central catheter (PICC) is widely used in chemotherapy of children with malignant tumors because of its safe operation and long indwelling time.

OBJECTIVE

To investigate the effect of intracavitary electroencephalogram (CEEG) localization technique on the success rate and complications of PICC in infants.

METHODS

A total of 180 children with PICC catheterization and maintenance at Shijiazhuang People's Hospital First Hospital from January 2017 to January 2020 were selected and divided into control group (n= 90 cases) and observation group (n= 90 cases). The control group observed the tip position of the fixed catheter through X-ray film and adjusted the catheter until its tip was located in the superior vena cava. The observation group used intracavitary electrocardiogram positioning technology. Comparison of the effects of two groups on the success rate and complications of PICC puncture in infants and young children.

RESULTS

The success rate of one puncture in the observation group was significantly higher than that in the control group (P< 0.05). Within one month of catheterization, 13 cases had complications, with an incidence rate of 16.00% lower than the control group's 34.00% (27/80) (P< 0.05). The screening test results showed that the specificity, sensitivity, Youden index, accuracy, kappa coefficient, positive and negative predictive value were 88.89%, 97.56%, 0.86, 96.00%, 0.86, 0.86, respectively. The measured values were 97.56% and 88.89% respectively, and the cost and time of localization were lower than those of X-ray.

CONCLUSION

The technique of intracavitary electrogram can be more accurate for infants to place the tip of central venous catheter through peripheral vein, which can effectively improve the success rate of one puncture with low cost, and has high reliability, accuracy and practicability, which is safe and effective.

Placement of peripherally inserted central catheter through upper versus lower limb vein in neonates: A meta-analysis of randomized controlled trials

AIM

Peripherally inserted central catheter (PICC) is an important treatment for the drug and nutrition administration in neonates. We aimed to evaluate the effects and safety of PICC placement through upper versus lower limb vein in neonates, to provide insights into the clinical PICC nursing care.

DESIGN

A meta-analysis.

METHODS

We searched the Cochrane Library, Web of Science, PubMed, Science Direct, China national knowledge infrastructure, Wanfang Data Knowledge Service Platform, China Weipu Database, China Biomedical Literature Database for published randomized controlled trials (RCTs) on the placement of PICC via upper limb and lower limb venipuncture. Two reviewers independently evaluated and cross-checked the quality of the included studies in accordance with the quality standards of the Cochrane Manual. We used RevMan 5.3 software for statistical processing.

RESULTS

A total of 12 RCTs were included in this meta-analysis. Meta-analysis indicated that compared with upper limb veins, PICC insertion through lower limb veins is beneficial to increase the one-time puncture success rate (relative risk [RR]  =  0.73, 95% confidence interval [CI]: 0.68-0.79) and the indwelling time (mean difference [MD] =  -3.60, 95% CI: -5.35 to -1.86), reduce the operation time (MD =  10.37, 95% CI: 7.48-13.26), estimated bleeding volume (MD =  0.55, 95% CI: 0.34-0.75), incidence of catheter ectopia (RR  =  2.46, 95% CI: 1.81-3.35), PICC-associated infection (RR  =  2.82, 95% CI: 1.65-4.83), exosmosis (RR  =  2.45, 95% CI: 1.49-4.04, p < .001) and phlebitis (RR  =  1.40, 95% CI: 1.03-1.90). No significant difference in the Incidence of catheter obstruction between the upper and lower limb veins (RR  =  1.20, 95% CI: 0.73-1.97, p = .48) was found.

PUBLIC CONTRIBUTION

There are certain advantages in neonatal PICC puncture through the lower limb vein. The lower limb vein may be the preferred choice for neonatal PICC puncture.

ECHOTIP-Ped: A structured protocol for ultrasound-based tip navigation and tip location during placement of central venous access devices in pediatric patients

Central venous access devices are routinely used in pediatric care for administration of fluids and medications and for drawing blood samples. The adoption of ultrasound guided venipuncture, the availability of bedside ultrasound devices and the use of intraprocedural methods for tip location have been shown to reduce procedure-related complications, as documented by the recommendations of most recent guidelines. In pediatric patients, bedside ultrasound is a promising tool not only for optimizing the choice of the vein and guiding the venipuncture, but also for ensuring an accurate and intraprocedural method of tip navigation and tip location. The aim of this paper is to review all the evidence about the accuracy of ultrasound methods for tip navigation and tip location in pediatric patients, and to suggest a structured protocol for clinical practice.
