Changes in upper extremity position cause migration of peripherally inserted central catheters in neonates

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.

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.

Proper Depth of Percutaneous Central Venous Catheter via the Great Saphenous Vein for Very Low Birth Weight Infants: A Single-Center, Prospective Cohort Study

BACKGROUND

A proper depth of percutaneous central venous catheter (PCVC) is very important to reduce procedural time and prevent various complications in very low birth weight (VLBW) infants who require minimal handling or have a sensitive skin. The objective of this study was to suggest a formula for faster and proper insertion of PCVC in VLBWIs to prevent unintended consequences of patients' conditions.

METHODS

Prospective data of VLBW infants admitted from June 2015 to January 2018 who had PCVC inserted via the great saphenous vein within seven days after birth were analyzed. Correlations of length of inserted PCVC with body weight, body length, and postmenstrual age at the date of PCVC insertion were determined with a linear regression analysis. Using results of this analysis, a formula to determine the optimal insertion length of PCVC was derived. Coefficient of determination was used to assess how well outcomes were replicated by the formula.

RESULTS

The formula to predict the proper insertion length of PCVC via the great saphenous vein at popliteal crease level was obtained as follows: Optimal Length (cm) = 3.8 × Body Weight (kg) + 11.1. With everyday movements such as flexion and extension of the lower extremities, the mean difference in catheter tip position was 7.0 ± 3.9 mm, which was not significant enough to escalate the risk of catheter tip displacement. The rate of catheter-related complications was as low as 4.9% in this study.

CONCLUSIONS

The formula derived from this study to predict the optimal PCVC insertion length could benefit VLBW infants by reducing procedural time and lowering the risk of complications.

A nurse-inserted peripherally inserted central catheter program in general pediatrics: a single-center experience

BACKGROUND

A peripherally inserted central catheter (PICC) with its tip preferably in the vena cava is essential in caring for patients with chronic conditions in general pediatrics. However, PICC-related complications are concerning and warrant further investigations.

OBJECTIVES

To share the experience of a nurse-inserted peripherally inserted central catheters (PICC) program initiated in a general pediatric department.

METHODS

A retrospective descriptive cohort study based on a prospectively collected database was conducted. All PICCs inserted in the departments of gastroenterology and pulmonology in a tertiary pediatric center from Dec. 2015 to Dec. 2019 were included in the study. Complications and risk factors were analyzed by comparing cases with and without complications. We also reported arm movements in correcting mal-positioned newly-inserted PICCs.

RESULTS

There were 169 cases with a median (IQR) age of 42(6, 108) months who received PICC insertion during a 4-year period. Inflammatory bowel disease was the leading diagnosis accounting for 25.4% (43/169) of all cases. The overall complication rate was 16.4 per 1000 catheter days with malposition and occlusion as the two most common complications. Multivariate models performed by logistic regression demonstrated that young age [p = 0.004, OR (95%CI) = 0.987(0.978, 0.996)] and small PICC diameter (1.9Fr, p = 0.003, OR (95%CI) = 3.936(1.578, 9.818)] were risk factors for PICC complications. Correction of malpositioned catheters was attempted and all succeeded in 9 eligible cases by using arm movements.

CONCLUSION

The nurse-inserted PICC program in general pediatrics is feasible with a low rate of complications. PICC tip malposition and occlusion were two major PICC-related complications when low age and small catheter lumina were major risk factors. Furtherly, arm manipulation potentially is an easy and effective approach for correcting malpositioned newly-inserted PICC catheters.

Tamponade and massive pleural effusions secondary to peripherally inserted central catheter in neonates-A complication to be aware of

Background

Peripherally inserted central catheters (PICC) are frequently used in neonatal intensive care units (NICU) to assist premature and critically ill neonates. Massive pleural effusions, pericardial effusions, and cardiac tamponade secondary to PICC are extremely uncommon but have potentially fatal consequences.

Objective

This study investigates the incidence of tamponade, large pleural, and pericardial effusions secondary to peripherally inserted central catheters in a neonatal intensive care unit at a tertiary care center over a 10-year period. It explores possible etiologies behind such complications and suggests preventative measures.

Study design

Retrospective analysis of neonates who were admitted to the NICU at the AUBMC between January 2010 and January 2020, and who required insertion of PICC. Neonates who developed tamponade, large pleural, or pericardial effusions secondary to PICC insertion were investigated.

Results

Four neonates developed significant life-threatening effusions. Urgent pericardiocentesis and chest tube placement were required in two and one patients, respectively. No fatalities were encountered.

Conclusion

The abrupt onset of hemodynamic instability without an obvious cause in any neonate with PICC in situ should raise suspicion of pleural or pericardial effusions. Timely diagnosis through bedside ultrasound, and prompt aggressive intervention are critical.

Rapidly Progressive Pericardial Effusion and Cardiac Tamponade in a Term Infant with an Umbilical Venous Catheter: A Case Report

Pericardial effusion (PCE) in neonates has various clinical presentations depending on the amount and speed of fluid accumulation and can cause cardiac tamponade (CT). We report a case of rapidly accumulating PCE and near-fatal CT with an umbilical venous catheter successfully resolved by emergent echo-guided pericardiocentesis in a term infant who had been hospitalized with meconium aspiration syndrome and persistent pulmonary hypertension. This case report suggests that if a patient with an intracardiac umbilical catheter shows sudden cardiopulmonary instability, the possibility of PCE and CT should be considered. Furthermore, if necessary, emergency drainage of the PCE and removal of the umbilical catheter should be immediately performed.

Diagnostic accuracy of ultrasound for localising peripherally inserted central catheter tips in infants in the neonatal intensive care unit: a systematic review and meta-analysis

BACKGROUND

Chest radiography after peripherally inserted central catheter insertion in infants is the reference standard method for verifying catheter tip position. The utilisation of ultrasound (US) for catheter placement confirmation in the neonatal and paediatric population has been the focus of many recent studies.

OBJECTIVE

In this systematic review we investigated the diagnostic accuracy of US for peripherally inserted central catheter tip confirmation in infants in the neonatal intensive care unit (NICU) MATERIALS AND METHODS: We conducted a systematic literature search of multiple databases. The study selection yielded eight articles, all of which had acceptable quality and homogeneity for inclusion in the meta-analysis. Sensitivity and specificity values were reported together with their respective 95% confidence intervals (CI).

RESULTS

After synthesising the eligible studies, we found that US had a sensitivity of 95.2% (95% CI 91.9-97.4%) and specificity of 71.4% (95% CI 59.4-81.6%) for confirming catheter tip position.

CONCLUSION

Analyses indicated that US is an excellent imaging test for localising catheter tip position in the NICU when compared to radiography. Ultrasonography is a sensitive, specific and timely imaging modality for confirming PICC tip position. In cases where US is unable to locate malpositioned PICC tips, a chest or combined chest-abdominal radiograph should be performed.

Echocardiographic Determination of Percutaneous Central Venous Catheters in the Superior Vena Cava: A Prospective Cohort Study

Malposition of percutaneous central venous catheters (PCVCs) in the superior vena cava (SVC) is common. We previously showed that real-time sonography was safer and faster than radiography in identifying PCVC tip location in the inferior vena cava (IVC). However, in preterm infants, determining PCVC tip location in the SVC is complicated by endotracheal or nasogastric tubes in situ and emphysematous lung conditions. We aimed to find an appropriate sonographic view by which to assess PCVC tip location in the SVC compared to the sonographic examination of PCVC in the IVC. Neonates (n = 50) with PCVCs in the SVC were enrolled and their data (gestational age, gender, birth weight, body weight at intervention, repositioning rate, and duration of tip assessment) were compared with retrospective data of 50 neonates with PCVCs in the IVC. The mean gestational age in the groups of IVC and SVC was 31.43 weeks and 32.16 weeks, respectively. The mean birth weight in the groups of IVC and SVC was 1642.18 g and 1792.00 g, respectively. Placement of an S12-4 ultrasound sector transducer to obtain clear parasternal views of the aorta allows visualization of PCVC tips in the SVC and near the cavoatrial junction. PCVC repositioning rates were not significantly different between the two groups (p = 0.092). Sonography examinations in the SVC had a longer duration than those in the IVC (p < 0.001). Sonography provides an accurate method for determining PCVC tip location in the SVC.

Percutaneous Route of Life: Chylothorax or Total Parenteral Nutrition-Related Bilateral Pleural Effusion in a Neonate?

Peripherally Inserted Central Catheter (PICC) lines are an essential tool in the management of premature neonates. Pleural effusion (PLE) secondary to the leakage of alimentation into the pleural cavity is an encountered complication of central-line total parenteral nutrition (TPN) administration. Methods: We review a case of a premature neonate who suffered large, bilateral PLE after insertion of an upper extremity PICC line for TPN. Results: Pleural fluid biochemical analysis confirmed PICC line infiltration, predominantly with monocytes, low protein, high triglycerides and high glucose. These results favored TPN leakage over chylothorax. Conclusions: To our knowledge, this is the first case of bilateral PLE due to PICC complication in a neonate, which highlights the importance of chylothorax differential diagnosis, the role of autopsy, and the need for clinical precautions when providing premature neonates with high osmolarity TPN.

Peripherally inserted central cathether migration in neonates: Incidence, timing and risk factors

BACKGROUND

PICC line use is a common practice in neonatal units, but it is associated with various complications. Catheter migration is the most common complication in neonates. Periodic imaging is recommended to monitor the tip position of the PICCs, but the optimal frequency is undetermined. The incidence, timing and risk factors that are associated with PICC migration have not been fully investigated beyond 24 hrs in neonates. The aim of the study was to determine the incidence, timing and risk factors that are associated with peripherally inserted central venous catheter (PICC) migration in neonates.

METHODS

This was a single center, retrospective study of 168 PICCs placed in 141 neonates in the neonatal intensive care unit (NICU) between 2015 and 2016. The incidence of catheter migration was determined radiographically at 12-24 hrs and every third day after insertion until it was removed.

RESULTS

Overall incidence of PICC migration was 28%and most commonly was detected within the first three days after PICC placement (83%). The incidence of PICC migration was higher in males. The PICC migration was associated with difficulty advancing the PICC at the time of insertion and PICC dressing change.

CONCLUSION

Serial evaluation of PICC placement in neonates is required to maintain proper position. Based on our experience in our unit, we recommend periodic imaging at 12-24 hrs and on the third day after PICC placement as most migration occurred within three days after insertion.

Time-Driven Cost Analysis of Noncuffed Venous Catheter Placement in Infants: Bedside versus IR Suite

PURPOSE

To compare the direct bundled costs of interventional radiology (IR) suite versus bedside placement of noncuffed central venous catheters in infants.

METHODS

A single-center retrospective review was performed of all noncuffed upper extremity (peripherally inserted central venous catheter [PICC]) and tunneled femoral (tunneled femoral central venous catheter [TCVC]) catheters placed in infants between January 1, 2018, and December 31, 2018. Propensity score matching was performed adjusting for age, birth weight, procedure weight, and catheter days. Process maps for each procedure were created based on location and sedation type. Technical success and complications were recorded for each placement. The total direct bundled cost for each catheter placement was calculated by summing the procedure and complication costs.

RESULTS

A total of 142 procedures were performed on 126 matched patients with a technical success of 96% at the bedside and 100% in the IR suite (P = .08). The complication rates did not significantly differ between the 2 groups (P = .51). The total direct bundled costs for catheter placement were $1421.3 ± 2213.2 at the bedside and $2256.8 ± 3264.7 in the IR suite (P = .001).

CONCLUSIONS

The bundled cost of bedside femoral catheter placement is significantly less than that of fluoroscopic TCVC and PICC placement performed in the IR suite, mainly related to differences in sedation costs.

A 1-Year Study on Association between Peripherally Inserted Central Catheter Tip Position and Complications in Neonates

AIMS

A peripherally inserted central catheter (PICC) is required in preterm neonates, especially those with low birth weight. However, PICC is associated with various complications resulting in increased morbidity and mortality. The objective of the study was to evaluate the association between PICC tip position and complications in neonates.

MATERIALS AND METHODS

One hundred neonates were recruited in a 1-year hospital-based, longitudinal, observational study. Radiographs were obtained to confirm the position of the catheter tip as central or noncentral in relation to vertebral level (T9-L5). The variables studied included site of insertion, duration of stay of PICC, time of removal, reason for removal, and associated complications. These were compared between the groups using SPSS version 20. Fisher's exact test was used to find the associations.

RESULTS

Most of the neonates were preterm (78%) and 81% were low birth weight. Catheter was placed in the right lower limb in most of the neonates (85%), and the catheter tip was central in position in 84% of neonates. The incidence of complications was observed in 29%. Noninfectious complications were common (26%) compared to infectious (3%). The most frequent PICC-induced complication was phlebitis (11%). Incidence of complications (P = 0.020), especially occlusion (P = 0.008), was significantly higher in neonates with noncentral catheter tip compared to the central tip.

CONCLUSION

We observed a high incidence of PICC-induced complications in neonates, with phlebitis being most common. Further, the incidence of complications is influenced by noncentral tip position.

Intracavitary electrocardiography for tip location during central venous catheterization: A narrative review of 70 years of clinical studies

Intracavitary electrocardiography is an accurate and non-invasive method for central venous access tip location. Using the catheter as a traveling intracavitary electrode, intracavitary electrocardiography is based on the increase in the detected amplitude of the P wave while approaching the cavoatrial junction. Despite having been adopted diffusely in clinical practice only in the last years, this method is not novel. In fact, it has first been described in the late 40s, during electrophysiological studies. After a long period of quiescence, it is in the last two decades of the XX century that intracavitary electrocardiography became popular as an effective mean of central venous catheters tip location. But the golden age of this technique began with the new millennium, as documented by high-quality studies in this period. In fact, in those years, intracavitary electrocardiography has been studied broadly, and important achievements in terms of comprehension of the technique, accuracy, and feasibility of the method in different populations and conditions (i.e. pediatrics, renal patients, atrial fibrillation) have been gained. In this review, we describe the technique, its history, and its current perspectives.

Premature infant with sudden respiratory distress

Here we describe a case of a premature neonate who showed initial improvement after being on invasive ventilation. She was gradually weaned to room air and was started on a feeding protocol for preterm infants together with total parenteral nutrition through a peripherally inserted central catheter (PICC) when she suddenly deteriorated and developed respiratory distress associated with signs of shock, requiring support from a high-setting mechanical ventilation as well as an inotropic support. A full sepsis work-up was ordered and she was started on antibiotics. The diagnosis was confirmed on chest X-ray and ultrasound, which showed automigration and displacement of the PICC line from its initial site on the left side to the right lung base, causing significant right-side pleural effusion which affected her haemodynamics. The PICC line was removed, and 30 hours later the pleural effusion completely resolved and the patient improved. She was discharged from hospital without any concerns with regard to growth and development during her regular follow-up.

Arrhythmias in Children with Peripherally Inserted Central Catheters (PICCs)

To analyze the prevalence, types, and risk factors for cardiac arrhythmias associated with peripherally inserted central catheters (PICCs) in children. This is a case-control single center retrospective study. From 3180 PICCs inserted in children (< 18 years old) between 2009 and 2013, cases with new onset arrhythmias were identified. Demographics, type and timing of arrhythmias, and possible risk factors were analyzed. ECGs, rhythm strips, physicians' records, and anti-arrhythmic management were confirmatory. The level of the PICC's tip in the superior vena cava (SVC) or right atrium (RA) was ascertained from chest X-rays and counted in rib units (RU) and vertebra units (VU). Cases were matched (1:1 ratio) to controls by weight and date of insertion. Descriptive statistics were performed. A two-sided p value < 0.05 was considered significant. Thirty-one children (1%) developed arrhythmias, 16/31 (56%) were males, and 24/31 (77%) were < 1-year age. Arrhythmias were atrial 22 (71%), ventricular 4 (13%), and undetermined 5 (16%). Median PICC dwell time was 16 days. 14/31 (45%) cases and 9/31 (29%) controls had underlying structural heart disease. PICCs central tip position was lower among cases than controls (RU 6 vs 5). Odds Ratio for developing arrhythmia was 4.5 (95% CI 0.98-20.83) if the tip lays below 6.25RU. Arrhythmias were resolved with anti-arrhythmic agents in 52% (16/31) and with PICC exchange/manipulation in 32% (10/31) cases. Two children died unrelated to arrhythmia. Prevalence of arrhythmias associated with PICCs in children is low (1%). Arrhythmias are 4.5 times more likely when PICC's central tip position is deeper than 6.25RU.

Iatrogenic Pleural Effusion Due to Extravasation of Parenteral Nutrition via an Epicutaneo Cava Catheter in Neonates: A Prospective Cohort Study

Background: Although Epicutaneo cava catheters (ECCs) are being routinely used for intravenous access for long-term parenteral nutrition and prolonged medication administration in neonates, ECC use can be associated with rare but acute life-threatening events such as pleural effusion (PE). It is important to identify and maintain the ECC tip in a central location for preventing complications. Recently, intracavitary electrocardiogram (IC-ECG) has been developed for the real-time monitoring and verification of ECC tip position. Objective: To investigate the causes and preventive measures of ECC-related PE in neonates. Methods: This prospective cohort study was conducted between January 2013 and December 2017. We observed and analyzed the clinical characteristics and causes of ECC-related PE. From January to December 2017, all ECCs were guided by IC-ECG. The incidence of ECC-related PE and first-attempt success rates were analyzed before and after the introduction of IC-ECG. Additionally, the sensitivity and specificity of IC-ECG were evaluated. Results: ECC-related PE was identified in 14 infants. Catheters were malpositioned in three cases; in the other 11 cases, catheters were located centrally on insertion but had migrated to non-central locations at the time of PE. After the introduction of IC-ECG, the incidence of PE was zero (P < 0.05). The incidence of ECC-related PE was lower when veins of the lower extremities were selected as the insertion site (P < 0.05). The first-attempt success rate was significantly higher in the group with IC-ECG-guided ECC placement than in the group without (P < 0.05). The sensitivity and specificity of IC-ECG were 97.9 and 84.6%, respectively. Conclusion: ECC-related PE can be associated with either primary malposition or migration of the catheter tip. IC-ECG can help detect malposition and migration of catheter tips and improve the first-attempt success rate. Choosing a lower extremity insertion site may help decrease the rate of ECC-related PE. In neonates, IC-ECG is a reliable positioning method for ECCs with superior sensitivity and specificity.

Decreasing radiographs in neonates through targeted quality improvement interventions

OBJECTIVE

Our aim was to decrease radiograph use for monitoring placement of peripherally inserted central catheters (PICC) and endotracheal tubes (ETT) in neonates admitted to the neonatal intensive care unit (NICU) by 20% from November 2017 to November 2018.

STUDY DESIGN

We carried out three Plan-Do-Study-Act (PDSA) cycles: (1) implementation of a radiograph protocol emphasizing ideal patient positioning, standard radiograph views and frequency, (2) standardizing ETT depth using the NRP guidelines, and (3) implementation of an institution specific ETT depth guideline.

RESULTS

The pre-intervention radiographs per PICC day was 0.86 versus a post-intervention value of 0.46 (P = 0.004). The pre-intervention radiographs per ETT day was 1.45 versus a post-intervention value of 1.07 (P = 0.002).

CONCLUSIONS

Our multidisciplinary NICU team performed a QI project, which resulted in more than a 20% decrease in the number of radiographs used for monitoring placement of PICCs and ETTs.

Complications of upper extremity versus lower extremity placed peripherally inserted central catheters in neonatal intensive care units: A meta-analysis

OBJECTIVE

To compare the risks of catheter-related complications between peripherally inserted central catheters placed via the upper and lower extremities in neonatal intensive care units.

RESEARCH METHODOLOGY

PUBMED, EMBASE, SCOPUS, and the Cochrane Library databases were searched from inception to 3 January 2019. All studies were of patients in neonatal intensive care units who underwent insertion of peripherally inserted central catheters and were published in English.

RESULTS

Eight studies covering 4405 peripherally inserted central catheters were included. The upper extremity group was associated with a higher risk of non-elective removal (OR = 1.41; 95% 1.16-1.72; p = 0.0007) and malposition (OR = 4.52, 95% CI 2.16-9.47; p < 0.0001) and a lower risk of thrombosis (OR = 0.23, 95% CI 0.07-0.77; p = 0.02) compared with the lower extremity group. There was no significant difference in mechanical complications, catheter-related infection, or phlebitis.

CONCLUSION

This meta-analysis showed that the lower extremity group was not associated with worse outcomes compared with the upper extremity group in the neonatal intensive care unit, with the exception of thrombosis. However, further prospective randomised controlled studies are needed to ensure the quality of the results.

The superiority of point of care ultrasound in localizing central venous line tip position over time

The primary objective was to study agreement between X-rays and point of care ultrasound (POC-US) in determining central venous line (CVL) tip position. The secondary objective was to examine malposition rates over time using POC-US. Fifty-six neonates were enrolled who had a CVL placed. Initial X-rays and POC-US were obtained. POC-US was performed daily thereafter for the total of 6 days. US video clips were acquired in four standard echocardiographic views: subcostal, four-chamber, and short- and long-axis parasternal views. Gwet's agreement coefficient (AC1) for agreement measured inter-rater reliability of X-rays and POC-US (correct position/malposition). A generalized linear mixed model for binary clustered data estimated malposition rate over time. All analyses were conducted using SAS version 9.4 and Agree Stat. The study included 108 "pairs" of X-rays and POC-US images. Agreement coefficient (AC1), with respect to correct position/malposition of CVL tip, was high AC1 = 0.872 (UVC-AC1 = 0.814, PICC-AC1 = 0.94). Among birth weight (BW) < 1000 g, 1000-1499 g, and BW > 1500 g, AC1 values were 0.922, 0.774, and 0.873, respectively. CVL tip malposition rate decreased over time.Conclusions: Agreement between POC-US and X-rays for CVL tip position was high, with the highest in BW < 1000 g. The data suggest that POC-US can be used for initial confirmation and follow up of CVL tip position. What is Known • X-ray is currently the gold standard for localizing central venous line (CVL) tip position. • Malposition of CVL tip can lead to life-threatening complications. What is New • POC-US is superior to X-ray as it can follow CVL tip position over time, detecting malpositioned lines, adjusting them in a timely manner thus preventing complications. • Standardizing CVL placement, X-ray acquisition, POC-US acquisition with four views with video clips and ultrasound operator training increases accuracy and thus agreement between X-ray and POC-US. • UVC tip is more likely to be malpositoned than PICC tip. Malposition of UVC tip using POC-US decreased over time due to shrinking of the umbilical cord in the first 48 of life.

Extravasation of total parenteral nutrition into the liver from an upper extremity peripherally inserted central venous catheter

Peripherally inserted central catheters (PICC) are the mainstay of central venous access in preterm infants, and one of the common procedures performed in neonatal intensive care unit (NICU). Complications of PICC include infection, mechanical dysfunction, thrombosis, migration, and extravasation of the infusate. In this report, we describe a case of PICC inserted from an upper extremity with migration into the inferior vena cava (IVC) and the hepatic vein associated with extravasation of the total parenteral nutrition (TPN) into the peritoneum and the liver. This case highlights the vigilance required not only to insert but for the maintenance of PICC to prevent complications associated with migration of PICC.

A misplaced peripherally inserted central catheter presenting as contralateral pleural effusion

A preterm neonate born at 27 weeks, with a birth weight of 555 g, was on continuous positive airway pressure (CPAP) for apnoea of prematurity and initially received total parenteral nutrition (TPN) through the umbilical venous catheter. Peripherally inserted central catheter (PICC) was inserted in the left basilica vein on day 8 to continue TPN. The baby developed respiratory distress with persistent hypoxia after TPN was initiated through the PICC line. The baby required mechanical ventilation due to worsening of respiratory distress, and chest X-ray, as well as ultrasound conducted 12 hours, postinfusion of TPN revealed right-sided pleural effusion. On careful observation, we could trace the PICC in the right lung area. The PICC line was removed immediately and the baby improved over the next 18 hours and was extubated to CPAP within the next 48 hours. We report this case of contralateral pleural effusion secondary to malposition of PICC line in an extremely preterm neonate.

Role of ultrasound for central catheter tip localization in neonates: a review of the current evidence

Central catheters are known as "life lines" in intensive care units and are used frequently in neonatal intensive care unit (NICU) for multiple indications. The central catheters used in NICU includes umbilical venous catheter (UVC), umbilical arterial catheter (UAC) and peripherally inserted central catheter (PICC) lines. The tip of these central lines needs to be in a correct position as malpositioned central line tips lead to many neonatal complications. Radiograph either abdomen or chest is the most widely used modality for locating the tip of the central catheter. There are many disadvantages of radiographic confirmation of tip position and recently ultrasound (USG)/echocardiography has been used for localization of catheter tip. USG provides real-time assessment of the tip position with other added advantages like no radiation exposure, need for minimal training for performing USG, minimal handling of the neonate, identification of migration of central lines and making repositioning of central lines under USG guidance. The present evidence supports the use of USG/Echo for localization of central catheter tip and USG has shown to have good sensitivity, specificity, positive predictive value and negative predictive value when compared with a radiograph. In this review, we discuss about the role of USG/Echo in the identification of tip of central catheters in neonatal care.

Massive pleural effusion on the contralateral side of a venous peripherally inserted central catheter

A preterm newborn infant, delivered at 30 weeks of gestation and 965 g birth weight, developed respiratory distress with resistant hypoxia after a central catheter line was inserted via the right venae brachialis on postnatal day 21. Left-sided massive pleural effusion, collapsed left lung with air bronchograms, and bidirectional shunting through reopened ductus arteriosus were detected by targeted neonatal echocardiography. Hydrothorax was drained under sonographic guidance, producing a milky-white fluid biochemically compatible with parenteral nutrition. We report this case of hydrothorax secondary to a misplaced central catheter on the contralateral side of its peripheral insertion. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46:140-144, 2018.

Perforations associated with peripherally inserted central catheters in a neonatal population

BACKGROUND

Peripherally inserted central catheters (PICCs) are increasingly used in neonates but perforations can result in devastating complications such as pericardial and pleural effusions. Identifying risk factors may guide surveillance and reduce morbidity and mortality.

OBJECTIVE

To determine the risk factors for PICC perforation in neonates.

MATERIALS AND METHODS

Retrospective case:control (1:2) study of neonates admitted between 2004-2014. Charts and imaging were reviewed for clinical and therapeutic risk factors.

RESULTS

Among 3,454 PICCs, 15 cases of perforation (incidence 0.4%, 5 pericardial effusions, 10 pleural effusions) were matched to 30 controls, based on gestation and insertion date. Timing of perforations post-insertion was median 4 days for pericardial effusions and 21.5 days for pleural effusions. A risk factor for pericardial effusion was lower weight at PICC insertion compared with controls. There were no statistically significant differences between cases and controls in catheter material, insertion site, PICC size and lumen number. Among upper limb PICCs, pericardial effusions were associated with tip positions more proximal to the heart at insertion (P=0.005) and at perforation (P=0.008), compared with controls. Pleural effusions were associated with tip positions more distal from the heart at perforation (P=0.008). Within 48 h before perforation, high/medium risk infusions included total parenteral nutrition (100% cases vs. 56.7% controls, P=0.002) and vancomycin (60% cases vs. 23.3% controls, P=0.02).

CONCLUSION

PICC-associated pericardial effusions and pleural effusions are rare but inherent risks and can occur at any time after insertion. Risk factors and etiologies are multifactorial, but PICC tip position may be a modifiable risk factor. To mitigate this risk, we have developed and disseminated guidelines for target PICC positions and routinely do radiographs to monitor PICCs for migration and malposition in our NICU. The increased knowledge of risk profiles from this study has helped focus surveillance efforts and facilitate early recognition and treatment.

A narrative review of long-term central venous access devices for the intensivist

This review introduces the different types of long-term central venous access devices, outlines their potential utility, examines potential complications associated with their use and outlines an approach to the management of these complications.

Variables decreasing tip movement of peripherally inserted central catheters in pediatric patients

BACKGROUND

The position of the tip of a peripherally inserted central catheter (PICC) is crucial; malposition can lead to malfunction of the line or life-threatening events (e.g., arrhythmias, perforation).

OBJECTIVE

To determine what factors other than arm position and accessed vein might influence the tip position of a PICC.

MATERIALS AND METHODS

Inclusion criteria were upper limb PICC placement, body weight <20 kg, intraoperative imaging with the arm in 0°, 45° and 90° abduction and an arm view marking the skin entry site relative to the shoulder. Evaluated variables included patient demographics, and PICC and insertion site characteristics. We measured central tip movement in rib units.

RESULTS

We included 112 children who received a PICC (42 girls/70 boys, mean age 31±13 months, mean weight 6.5±4.9 kg). The overall range of central tip movement was -1 to +4 rib units (mean +0.8±0.7 rib units). Silicone PICCs moved significantly less than polyurethane PICCs (P<0.05). PICCs placed in the cephalic vein moved significantly less than those placed in other veins (P<0.05). Patient demographics and PICC characteristics (size, number of lumens, left or right arm accessed, length of the line) did not influence the range of central tip movement of a PICC (P>0.05).

CONCLUSION

Silicone PICCs and PICCs inserted into the cephalic vein move less than PICCs made of polyurethane and PICCs inserted into the brachial and basilic veins. These findings might assist operators in deciding which PICC to place in children in a given clinical context.

Percutaneously Inserted Central Catheter-Related Pleural Effusion in a Level III Neonatal Intensive Care Unit: A 5-Year Review (2008-2012)

BACKGROUND

Although peripherally inserted central catheters (PICCs) provide vascular access in newborns who require parenteral nutrition and medications, they can be associated with complications that lead to significant morbidity and mortality.

OBJECTIVES

To describe the characteristics of pleural effusion (PLE) associated with PICC use in a large level III neonatal intensive care unit.

DESIGN/METHODS

A retrospective review of PICC-related PLE in newborns was conducted over a 5-year period, from 2008-2012.

RESULTS

A total of 926 PICCs were inserted, accounting for 17,606 catheter days. PICC-related PLE was identified in 7 infants, with an incidence of 0.4 per 1000 catheter days. Infants who developed PLE had a median gestational age of 28 weeks (range, 24-38 weeks) and birth weight of 735 g (range, 500-2975 g). PICCs were inserted at a median age of 4 days (range, 3-11 days). The median time from catheter insertion to the development of PLE was 16 days (range, 7-75 days). In all cases, the catheter tips were centrally located at the time of insertion but migrated to the subclavian veins or tributaries at the time of the events.

CONCLUSION

PICC-related PLE can be associated with the migration of PICC tips to noncentral locations, despite optimal positioning of the tip at the time of insertion. Attention should be paid to migration of catheter tips on subsequent x-ray films. For PICCs inserted via upper limb or scalp, serial follow-up x-rays, beginning 1 week after insertion, may be helpful to detect migration of catheter tips and identify patients at risk.

[Catheter tip position and risk of mechanical complications in a neonatal unit]

INTRODUCTION

The use of central catheters (CC) is associated with mechanical complications (MC).

OBJECTIVE

Our objetive was to determine the relationship between CC positions and associated MC in neonates.

MATERIAL

A descriptive analytical study was performed over a six year period in the NICU of the University Hospital Santa Lucía de Cartagena. Details were collected on the CC used, indication, reason for withdrawal, position in the imaging, MC, and treatment arising from them, as well as epidemiological data.

RESULTS

Of the total of 604 CC studied, the majority (347) were via the umbilical vein, followed by epicutaneous (193), and femoral vein (34). There were MC in 14.2% of catheters. Incorrect position of the tip was associated with greater MC (21.1 vs 8.2%; P<.001), including withdrawal due to MC (8.4 vs 3.1%; P<.01), extravasation (4.9 vs 1.9%; P<.05), pleural and pericardial effusions (1.4 vs 0.0%; P<.05), liver haematomas (4.6 vs 0.6%; P<.01), and ascites (2.8 vs 0.0%; P<.01). The midclavicular epicutaneous position of the tip was associated with greater MC (18.5 vs 6.8%; P<.05) than the brachiocephalic (0 vs 6.8%;NS). The low and ductal position of the umbilical vein catheter was also associated with higher rates of MC (24.5 vs 6%; P<.001 and 27 vs 6%; P<.001) due to the position of the tip. The most common complication was accidentally dislodged catheter.

CONCLUSIONS

The incorrect location of the tip was associated with more MC. The midclavicular epicutaneous had more risk than centrally or brachiocephalic locations. The low and ductal positions of the umbilical vein catheter were associated with higher rates of MC.

Peripherally Inserted Central Catheters Complicated by Vascular Erosion in Neonates

Peripherally inserted central catheters (PICCs) are widely used in the pediatric population, and their use continues to grow in popularity. These catheters provide a reliable source of venous access to neonatal patients but can also be the cause of life-threatening complications. There are several well-documented complications such as infections, catheter thrombosis, vascular extravasations, and fractured catheters. However, the complication of vascular erosion into the pleural space using both small and silicone-based catheters is rarely described. After obtaining institutional review board approval, we identified 4 cases to review of PICCs complicated by vascular erosions in the past 2 years. Herein, we also review the current literature of PICC complications. Getting the catheter tip as close to the atrial-caval junction as possible and confirmation of this placement are of the utmost importance. The thick wall of the vena cava near the atrium seems to be less likely to perforate; in addition, this position provides increased volume and turbulence to help dilute the hyperosmolar fluid, which seems to also be a factor in this complication. A daily screening chest x-ray in patients with upper extremity PICCs and ongoing parenteral nutrition (PN) are not necessary at this time given the overall low rate of vascular erosion and concerns regarding excessive radiation exposure in pediatric populations. However, a low threshold for chest x-ray imaging in patients with even mild respiratory symptoms in the setting of upper extremity PN is recommended.

Cardiac tamponade secondary to perforation of innominate vein following central line insertion in a neonate

Cardiac tamponade following central line in a neonate is rare and an uncommon situation; however, it is potentially reversible when it is diagnosed in time. We report a case of cardiac tamponade following central line insertion. A 10-day-old 2.2 kg girl operated for obstructed total anomalous pulmonary venous connections had neckline slipped out during extubation. Attempted cannulations of right femoral vein were unsuccessful. At the end of the left internal jugular vein cannulaton, there was a sudden cardiorespiratory arrest. Immediate transthoracic echocardiogram showed left pleural and pericardial collection. Chest was opened and the catheter tip was seen in the thoracic cavity after puncturing the innominate vein. The catheter was removed and the vent was repaired.

Neonatal peripherally inserted central catheter practices and their association with demographics, training, and radiographic monitoring: results from a national survey

The goal of this secondary analysis of results from a national survey of peripherally inserted central catheters (PICCs) practices in neonates was to determine whether demographics and types of training were associated with differing radiographic confirmation practices of these catheters. Correlational analyses were performed on the 2010 national database of neonatal PICC practices. The sample consisted of 187 respondents, representing 25% of the level III neonatal intensive care units (NICUs) of more than 20 beds in the United States. The key factors examined were geographic location, size of NICU, academic affiliation, and type of training related to radiographic confirmation of the catheter tip position, routine monitoring and reconfirmation of the catheter tip position following adjustments, and associated patient positioning practices for consistent evaluation of the catheter tip position. Formal training and annual retraining were statistically significantly associated with consistent patient positioning practices for more accurate monitoring of the catheter tip position and acceptable tip location. Size of NICU and academic affiliation were not associated with differences in practices. Adherence to specific national guidelines and recommendations for care of infants with PICCs is significantly impacted by formal training and annual retraining. This underscores the importance of education and annual retraining in preventing PICC-related complications beyond the crucial prevention of central line-associated bloodstream infections.

Evaluation of neonatal peripherally inserted central catheter tip movement in a consistent upper extremity position

OBJECTIVE

To compare the effect of standardized upper extremity position versus varied upper extremity positions on neonatal peripherally inserted central catheter (PICC) tip placement and movement. Secondary outcomes assessed were compliance with education, implementation, and complication rates.

STUDY DESIGN

Tip movement was analyzed between 136 post-PICC insertion x-ray pairs from 72 infants in the 6 months before and after standardization of upper extremity position. Tip movement was regressed over days between x-ray pairs, respiratory support, absolute weight change, and insertion vein.

RESULTS

There was no difference in PICC tip movement among varied analysis pairs or when standard position pairs were compared with pairs that were in a same nonstandard position. Days between x-rays, respiratory support, absolute weight change, and insertion vein did not predict tip movement. Attendance at education sessions was 100%. Compliance with the new standard was 73%. Complication rates were not significantly different.

CONCLUSION

Standardization of upper extremity position during neonatal PICC confirmation x-rays did not alter PICC tip movement.

Superiority of targeted neonatal echocardiography for umbilical venous catheter tip localization: accuracy of a clinician performance model

OBJECTIVES

To compare targeted neonatal echocardiography (TnECHO) and antero-posterior (AP) chest radiographs in the localization of the umbilical venous catheter (UVC) tip and to determine the accuracy of UVC tip localization by TnECHO when performed by a trained cohort of pediatric housestaff physicians.

STUDY DESIGN

Prospective, observational study of consecutive neonates requiring UVC insertion, in a tertiary care center, in an 18-month period. Chest radiographs reporting optimal position of the UVC tip were compared with the TnECHO results of the pediatric cardiologist. The latter was also compared with the results of TnECHO performed by the pediatric housestaff physicians.

RESULT

Thirty neonates with birth weight ranging between 270 and 4490 g and gestational age ranging between 24 and 44 weeks were enrolled. Nine patients (27%) required UVC tip repositioning as the cardiologist performed TnECHO revealed sub-optimal tip position despite optimal position on chest radiography. Among them, four had the UVC tip in the right atrium and five in the left atrium. Compared with the cardiologist, the housestaff physicians had reported TnECHO with a high-accuracy rate (area under the receiver operating characteristic curve=0.81).

CONCLUSION

TnECHO is superior to chest radiography for identifying malpositioned catheters. TnECHO performed by pediatric housestaff physicians with basic training, demonstrated high-accuracy rates.

A randomized controlled trial of ultrasound-guided peripherally inserted central catheters compared with standard radiograph in neonates

OBJECTIVE

The placement of a peripherally inserted central catheter (PICC) routinely incorporates tip position confirmation using standard radiographs. In this study, we sought to determine whether real-time ultrasound (RTUS) could be used to place a PICC in a shorter time period, with fewer manipulations and fewer radiographs than the use of radiographs to determine accurate placement.

STUDY DESIGN

This was a prospective, randomized, trial of infants who required PICC placement. Catheters were placed using either standard radiograph, with blinded evaluation of the catheters using RTUS or with RTUS guidance, with input on catheter tip location. The number of radiographs required to confirm proper positioning, duration of the procedure and manipulations of the lines were recorded for both groups. Final confirmation of PICC placement was by radiographs in both groups.

RESULT

A total of 64 patients were enrolled in the study, with 16 failed PICC attempts. Of the 48 remaining infants, 28 were in the standard placement group and 20 were in the RTUS-guided group. The mean ± s.d. gestational ages and weight at time of placement were 30 ± 4 weeks and 1229 ± 485 g, respectively. The RTUS use significantly decreased the time of line placement by 30 min (P=0.034), and decreased the median number of manipulations (0 vs 1, P=0.032) and radiographs (1 vs 2 P=0.001) taken to place the catheters. Early identification of the PICC by RTUS was possible in all cases and would have saved an additional 38 min if radiographs were not required.

CONCLUSION

In the hands of ultrasound (US)-experienced neonatologists, RTUS-guided PICC placement reduces catheter insertion duration, and is associated with fewer manipulations and radiographs when compared with conventional placement.

Echocardiography allows more accurate placement of peripherally inserted central catheters in low birthweight infants

AIM

The use of plain radiographs provides limited information on the placement of peripherally inserted central catheters (PICCs). Moreover, changes in upper extremity positioning cause migration of the catheters in neonates. This study aimed to investigate the use of echocardiography for determining catheter tip position, compared with plain radiographs, in low birthweight (LBW) infants in a tertiary neonatal intensive care unit.

METHODS

The study examined the placement of 109 catheters in 89 infants born between September 2010 and December 2012. The placement of these catheters was controlled by echocardiography, with the patient's shoulder in adduction and the elbow in flexion. The number of catheter tips, echocardiographically identified within the heart, was expressed as a percentage of the total catheters deemed to be well positioned on plain radiographs.

RESULTS

The number of catheter tips that were echocardiographically identified within the heart was significant (25%, p < 0.001). Twenty-three catheters were repositioned to be outside of the heart, without any complications.

CONCLUSION

This study demonstrated the value of echocardiography for identifying the positioning of catheter tips in LBW infants. Echocardiography, coupled with initial plain radiographs, should be the gold standard for assessing PICC tip positions in those infants.

Repositioning techniques of malpositioned peripherally inserted central catheters

AIMS AND OBJECTIVES

To describe potential repositioning techniques of malpositioned peripherally inserted central catheters.

BACKGROUND

Various repositioning methods have been applied in clinical practice in managing malpositioned peripherally inserted central catheters, and many of them are proved effective. However, little publication reviewed on those literatures describing repositioning techniques to malpositioned peripherally inserted central catheters.

DESIGN

Systematic review. The repositioning techniques were classified and concretely described according to different locations of malpositioned peripherally inserted central catheter tips.

METHODS

Literature and relevant guidelines were reviewed, focusing on malpositioned locations and incidence, as well as repositioning skills to peripherally inserted central venous catheters. Six databases were searched, including MEDLINE, web of science, CINAHL, Cochrane library, Wanfang database and Chinese National Knowledge Infrastructure. The articles (n = 21) were analysed using inductive content analysis.

RESULTS

The malpositioned locations of postplacement peripherally inserted central catheter tips mainly include right atrium, right ventricular, axillary vein, ipsilateral and contralateral internal jugular vein, subclavian vein, brachiocephalic vein, other small venous branches or catheter looped. Repositioning techniques contained automatic reposition, manual repositioning techniques, re-advancing catheters and catheters' replacement according to different malpositioned patterns.

CONCLUSIONS

The most appropriate repositioning techniques should be adopted on the basis of malpositioned locations, direction and length of the malpositioned tip, patients' integrated conditions and available medical equipments to maintain the catheter tip in the best position.

RELEVANCE TO CLINICAL PRACTICE

The repositioning techniques described in this review can be applied in clinical practice to ensure the infusion therapy through peripherally inserted central catheter more economical and safe.

Central venous catheters in premature babies: radiological evaluation, malpositioning and complications

Central venous catheters are important in the care for prematurely born children in the neonatal intensive care unit. The purpose of this pictorial essay is to illustrate correct positioning, malpositioning and possible complications of such devices.

Cardiac tamponade due to peripheral inserted central catheter in newborn

This article reports the case of an adverse event of cardiac tamponade associated with central catheter peripheral insertion in a premature newborn. The approach was pericardial puncture, which reversed the cardiorespiratory arrest. The newborn showed good clinical progress and was discharged from hospital with no complications associated with the event.

Vascular access in the neonate

Up to recently, inserting venous or arterial 'lines' in the neonate was essentially based on clinical skill and experience. The recent advent of portable ultrasound (US) machines with paediatric probes has resulted in the development of new approaches that, if correctly learned and used, should allow quicker and safer vascular access in this population. Both classic and new techniques are reviewed on the basis of literature and authors' experience.

[Peripherally inserted central catheter: description of its use in neonatal and pediatric ICU]

The purpose of this descriptive, retrospective, documental study is to describe the use of peripherally inserted central catheters (PICC) in a neonatal and pediatric intensive care unit regarding their insertion, maintenance, and removal. This study also characterized the population which received the catheter through descriptive and statistical analysis of 176 instruments filled out by nurses, in a two year period. The population attended consisted of 125 patients, mainly premature (43.2%) and male (60%). The basilic and cephalic (43.2%) veins were primarily used for the insertion of a 1.9Fr (85.8%) catheter. The success rate was 98.9% in the punctures, but anticipated removal occurred due to obstruction (25%), infiltration (18%), suspected contamination (16.6%), traction (13.9%), rupture (11.2%), accidental removal (8.3%), phlebitis (4.2%), cyanosis (1.4%), and migration (1.4%), with an average period of permanence of 14.5 days. In order to maintain the catheter professional education and preparation are required to qualify care.

Neonatal PICC: one unit's six-year experience with limiting catheter complications

Safe dressing techniques for neonatal peripherally inserted central catheters (PICCs) remain controversial in the literature. This article describes one unit's experience with the placement and management of 491 PICCs during a six-year period with more than 5,600 catheter days. The dressing technique described in this article differs from that seen in the literature with the addition of a protective base layer. Catheter complication rates are low, and catheter dressing changes are minimized with this dressing technique.

Are supine chest and abdominal radiographs the best way to confirm PICC placement in neonates?

BACKGROUND

Peripherally inserted central catheters (PICCs) are commonly used in NICUs. Although they have many benefits, they also have many potential complications. Confirming catheter tip position is essential to decreasing complications, but the best method to achieve confirmation is unclear.

OBJECTIVES

Literature review for studies that address line position confirmation to assist health care providers in evaluating the available research and to identify gaps in the literature.

METHOD

A literature search of four major databases followed by an ancestry approach was performed. Articles reviewed specifically discuss PICC lines and PICC line placement confirmation.

RESULTS

Data on confirming PICC placement were lacking. Fluoroscopic placement is ideal, but cannot be done at the bedside and is costly. Supine chest radiograph is the most widely used method and is convenient, but when line tip position is unclear, contrast or ultrasound confirmation can be used. When PICC lines are placed in the saphenous vein, infants may benefit from supine and lateral abdominal radiographs to ensure placement in the inferior vena cava.

DISCUSSION

More studies are needed to generalize findings. PICC line tips should be located in the superior vena cava or inferior vena cava close to the junction with the right atrium (0.5-1 cm outside of the cardiac chambers in premature infants and 1-2 cm outside of the cardiac chambers in larger infants). Arm position is very important when performing radiographs for placement because movement of the arm can cause migration of the catheter. There is also significant inter-observer variability when identifying line tip position.
