Real-time point-of-care ultrasound-guided correction of PICC line placement by external manipulation of the upper extremity

Correcting Peripherally Inserted Central Catheter Placement by External Manipulation of the Upper Limb Extremity

Peripherally inserted central catheters (PICCs) play a critical role in neonatal intensive care units (NICUs), facilitating treatment in premature and critically ill neonates. However, achieving optimal PICC placement can present challenges, requiring meticulous monitoring and adjustment. Here, we describe the case of a 52-day-old, 1.9 kg preterm infant in the NICU requiring a central venous catheter for antibiotics and antifungals. Despite initial insertion into the basilic vein of the right forearm, imaging revealed the catheter's deviation into the right internal jugular vein. Leveraging the influence of arm position on catheter tip depth, external manipulation of the infant's right arm successfully repositioned the catheter tip into the superior vena cava (SVC). This case highlights the significant impact of arm positioning on PICC placement and underscores the efficacy of external extremity manipulation as a simple, non-invasive technique to adjust catheter position. Such innovative strategies offer promising alternatives to invasive interventions, emphasizing the importance of dynamic monitoring and adjustment techniques in neonatal PICC management.

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.

Therapeutic Effect of Ultrasound-Guided Peripherally Inserted Central Catheter Combined with Predictive Nursing in Patients with Large-Area Severe Burns

This study was aimed to explore the application value of ultrasound-guided peripherally inserted central catheter (PICC) combined with predictive nursing in the treatment of large-area severe burns. 88 patients with large-area severe burns who visited hospital were chosen as the research objects. They were randomly divided into the observation group and the control group, with 44 cases in each. The patients in the observation group were treated with ultrasound-guided PICC combined with predictive nursing, while those in the control group were treated with traditional PICC and nursing methods. Then, the anxiety of patients was compared between groups by the Self-rating Anxiety Scale (SAS), while the depression was compared by the Self-rating Depression Scale (SDS). The pain of the patients was analyzed by the McGill Pain Questionnaire (MPQ), and a self-made nursing satisfaction questionnaire was adopted to evaluate the nursing satisfaction. The surgery-related indicators of the patients were detected and recorded (the success rate of one-time puncture, the success rate of one-time catheter placement, incidence of complications, heart rate, blood pressure, etc.). The success rates of one-time puncture (93% vs. 86%) and of catheter placement (95% vs. 81%) in the observation group were significantly higher than those in the control group, P < 0.05. The pain scores of the observation group were much lower than those of the control group at each time period, P < 0.05. The number of patients with negative emotions such as anxiety and depression in the observation group was markedly less than that in the control group. The incidence of complications in the observation group was notably lower than that in the control group (4.5% vs 18%), P < 0.05. The nursing satisfaction of the observation group was significantly higher than that of the control group (93% vs 79.5%), P < 0.05. In conclusion, ultrasound-guided PICC and predictive nursing had high clinical application values in the treatment of patients with large-area severe burns.

Joint time-frequency analysis of visible laser reflections in a sheep heart

Limited methods exist to confirm the position of cardiovascular devices in the superior vena cava or right atrium of the heart. The aim of this study was to design, test and validate the feasibility of whether an optical fiber-based instrument could accurately distinguish when a cardiovascular catheter was located in the superior vena cava vs in the right atrium. An optical fiber was placed in a cardiovascular catheter which was inserted into a living sheep and guided to the vicinity of the heart where diode laser-based reflection intensity data were simultaneously gathered from two visible wavelengths of light reflected from the venous and atrial tissue surfaces near the cavoatrial junction. The time series data were postoperatively analyzed using methods of joint time-frequency analysis and validated against catheter positions determined with fluoroscopy and ECG. The system was successful in distinguishing the location of the superior vena cava from the right atrium.

Inserting central lines via the peripheral circulation in neonates

Peripherally inserted central catheters (PICCs) are extensively used in neonatal intensive and high-dependency care settings. These intravenous catheters provide medium to longer-term access to the circulatory system for the delivery of medications, parenteral nutrition and the like. Catheters are available in a variety of bespoke designs and materials, each with their unique characteristics, benefits and limitations. PICCs are frequently inserted in a sterile zone cot-side procedure, one that requires an advanced knowledge base, technical skill and training. This article relates some important practical advice around managing minor complications that can be encountered while using the modified Seldinger technique (MST) to insert neonatal PICCs, which can make this procedure a less stressful experience for both infants and health professionals.
