Purpose: To evaluate the feasibility and accuracy of intracavitary electrocardiogram for verifying tip position of peripherally inserted central catheters in cancer patients during follow-up period. Methods: From March 2015 to October 2015, 126 patients involved in eight hospitals who underwent peripherally inserted central catheter placement received intracavitary electrocardiogram and chest X-ray to verify position of the catheter tip during follow-up period. Their intracavitary electrocardiogram was compared with surface electrocardiogram to judge catheter tip landing zone in one of three different anatomical zones. The amplitude of intracavitary electrocardiogram P wave and the ratio of intracavitary electrocardiogram P wave/surface electrocardiogram P wave were measured and showed correlation with catheter tip position confirmed by chest X-ray. Based on chest X-ray principle, all the cases were assigned into three intracavitary electrocardiogram groups to explore the optimal cut-off values for intracavitary electrocardiogram P wave and intracavitary electrocardiogram P wave/surface electrocardiogram P wave by analyzing the receiver operating characteristic. Results: No technique-related complications or adverse events occurred in this study. The matching rate between intracavitary electrocardiogram and chest X-ray method was 93.7%. The optimal cut-off values for intracavitary electrocardiogram P wave were set from 3.15 to 3.75 mV, and intracavitary electrocardiogram P wave/surface electrocardiogram P wave from 1.65 to 3.25. Conclusions: It is demonstrated in this retrospective multicenter study that the intracavitary electrocardiogram method for verifying tip position of peripherally inserted central catheter during follow-up period is feasible and accurate in all adult patients with cancer.

Objective To evaluate the application of ultrasound for the localization of the tip position of peripherally inserted central catheters (PICCs) in newborn infants. Study Design This study was a retrospective analysis on ultrasonic localization for PICC placement conducted in our department over the past 2 years. Ultrasonic localization was performed immediately after PICC placement in all neonatal patients. Successful PICC placement was confirmed if the PICC tip position was located at the inferior/superior cavoatrial junction. Chest X-ray localization was performed on 32 infants immediately after ultrasound examination to compare the accuracy of ultrasound localization. Results Of the 186 patients, 174 (93.5%) had successful PICC placement on the first attempt. In 11 (5.9%) patients, the catheter tip was placed beyond the ideal location as follows: too deep (in the right atrium) in 4 patients, too shallow in 4 patients, and malpositioned in 3 patients. Both the sensitivity and the specificity of ultrasound for identifying PICC tip localization were 100%. Complications occurred in 2.7% of this group of patients. Conclusion Ultrasonic localization of the PICC tip position is a timely, accurate, and reliable method and can identify the catheter tip with high accuracy. This method could be widely applied in neonatal wards.

Purpose: The neonatologists of Sant’Anna and San Sebastiano Hospital of Caserta have carried out a pilot study investigating the safety, feasibility, and accuracy of intracavitary electrocardiography for neonatal epicutaneous cava catheter tip positioning. Patients and methods: We enrolled 39 neonates (1–28 days of postnatal age or correct age lower than 41 weeks) requiring epicutaneous cava catheter in the district of superior vena cava (head–neck or upper limbs). Intracavitary electrocardiography was applicable in 38 neonates. Results: No significant complications related to intracavitary electrocardiography occurred in the studied neonates. The increase in P wave on intracavitary electrocardiography was detected in 30 cases. Of the remaining eight cases, six malpositioned catheters tipped out of cavoatrial junction–target zone (chest x-ray and echocardiographical control) and two were false negative (tip located in target zone). The match between intracavitary electrocardiography and x-ray was observed in 29/38 cases, and the same ratio between intracavitary electrocardiography and echocardiography was detected. Conclusion: We conclude that the intracavitary electrocardiography method is safe and accurate in neonates as demonstrated in pediatric and adult patients. The applicability of the method is 97% and its feasibility is 79%. The overall accuracy is 76% but it rises to 97% if “peak” P wave is detected.

Abstract Objective We determined intra- and inter-rater agreement for umbilical arterial/venous catheter (umbilical arterial catheter [UAC] and umbilical venous catheter [UVC], respectively) positions on supine anteroposterior (AP) and horizontal dorsal decubitus (HDD) X-ray views to determine whether two views are routinely required. Study Design This retrospective study was conducted in McMaster University, Canada. Pairs of AP and HDD radiographs were coded and rated in random sequence by two experienced raters. Primary outcome was intra-rater agreement (κ) between AP and HDD views for UVC catheter tip position. Secondary outcomes included inter-rater κ for UVC position; inter- and intra-rater κ for UAC position, inter- and intra-rater κ for follow-up action. To detect κ of 0.8 (width of 95% confidence interval = 0.1), 138 radiograph pairs were required. Results Intra-rater agreement tended to be higher for UVC versus UAC position (Rater#1: κ = 0.44 vs. 0.16, respectively, p = 0.08; and #2: κ = 0.56 vs. 0.47, respectively, p = 0.5). Inter-rater agreement was higher on AP versus HDD view for UVC position (κ = 0.6 vs. 0.29, respectively, p = 0.03) and action recommended for UVC (κ = 0.61 and 0.19, respectively, p < 0.001). Conclusion AP is superior to HDD view for UVC.

Femorally inserted central catheters (FICCs) are frequently required for central access in children. Ultrasound can accurately locate the catheter tip in most cases and its use is increasing in clinical vascular access practice. In patients with poor acoustic windows, intracavitary electrocardiogram (IC-ECG) is an alternative to ultrasound-guidance for FICC positioning. A case series of three patients demonstrate methods of FICC positioning in children. The first patient had excellent acoustic windows and ultrasound-guided FICC positioning is described in conjunction with IC-ECG measurements. The following two patients had poor acoustic windows, thus IC-ECG guided FICC tip position. The use of FICCs in children has increased in recent years. Ultrasound has emerged as a reliable method of assessing FICC tip location. IC-ECG is an accurate and complementary method of assessing FICC tip location, but can be a primary method when ultrasound is not available or cannot directly visualize the catheter. IC-ECG P-wave characteristics identify optimal tip position at the inferior cavoatrial junction and are different from characteristics at the superior cavoatrial junction.

Background The intracavitary electrocardiogram (IC-ECG) method has been used for the tip location of central venous access devices for the advantage of being safe, accurate and highly cost effective. However, long-term follow-up is rare. This randomized clinical trial aimed to evaluate the long-term complications of peripherally inserted central catheters (PICCs) positioned by the IC-ECG method. Methods We randomized 2250 patients who needed PICC placement to either a landmark length estimation supplemented by IC-ECG positioned group (ECG group) or the traditional landmark length estimation alone group (control group) in a 2:1 allocation. Post-procedural chest X-rays were applied to confirm tip position. Follow-up was performed monthly to six months. Standard statistics analyses were performed with the SAS 9.13 software, and p < 0.05 was considered significant. Results As evaluated by post-procedural chest X-ray, tip location in the ECG group had a first-attempt success (catheter tip located at optimal position) of 91.7% (95% confidence interval (CI): 90.3%–93.1%), significantly higher than 78.9% (95% CI: 76.0%–81.9%) observed in the control group (p < 0.001). At six-month follow-up, in the control group, frequency of total complications was 9.5%, including the exit site infection (4.0%), phlebitis (1.3%), deep venous thrombosis (1.5%), liquid extravasation (2.9%) and mechanical failure (1.9%). The IC-ECG group had significantly lower rates of complications (6.4%, p < 0.001), including the exit site infection (2.7%, p > 0.05), phlebitis (1.1%, p > 0.05), deep venous thrombosis (1.2%, p > 0.05), liquid extravasation (2.4%, p > 0.05) and mechanical failure (1.2%, p > 0.05). In the univariable logistic regression analysis, ECG method, other diseases and upper arms were the independent protective factors, and the number of adjustment procedures (n ≥ 2) were the independent risk factors of the complications. Conclusions The intra-procedural tip location by IC-ECG is more safe and accurate than the traditional method of verifying tip location only post-procedurally, by chest X-ray.

Abstract Background: The current standard of care for Peripherally Inserted Central Catheters (PICCs) is radiological confirmation of terminal tip location. Tip location practices in Europe have used electrocardiographic (EKG) guided positioning for central venous catheters for more than twenty years with tip positioning safely confirmed over thousands of insertions (Madias, 2003). The goal of this group was to confirm the findings of a study performed by Pittiruti and his team; and to establish safe function in the use of EKG guidance for verification of terminal tip position with PICCs placed at McKenzie Willamette Medical Center. Methods: In 2008/2009 McKenzie Willamette Medical Center conducted a study to determine whether or not EKG guidance can be used as a reliable means to accurately place and confirm terminal tip location of PICCs. A group of trained nurses performed PICC placement using EKG guidance followed by radiological confirmation of SVC position. All PICCs placed from October 2008 to December 2009 were included in the study. Tip location was confirmed using either radiological confirmation alone, EKG plus radiological confirmation, or EKG alone. Results: A total of 417 PICCs were placed during the study period. EKG guidance alone was used in the placement and confirmation of 168 PICCs. Both EKG and chest x-ray confirmation were used in the placement of 82 of the PICCs; 240 of the PICCs were placed with the use of EKG and then position correlated using the traditional chest x-ray procedure. Discussion: EKG guided PICC placement proved accurate in consistently guiding the terminal tip to the superior vena cava (SVC). The procedure was easily taught and duplicated by members of the PICC team. The study demonstrated a definite correlation between the height (size) of the P-wave and the location of the terminal tip within the SVC. With knowledge of this correlation, transition from placing PICCs using EKG guidance with chest x-ray confirmation to confirmation of tip placement using just EKG guidance without chest x-ray confirmation was attained. Application of EKG placement/confirmation performed during insertion saves time previously spent waiting for x-ray confirmation readings, saves cost of chest x-ray, prevents patient exposure to radiation and saves time required for tip repositioning of malpositioned tips found after the end of the procedure.

Abstract Background There is no consensus on the imaging modality to be used in the diagnosis and management of Coronavirus disease 2019 (COVID-19) pneumonia. The purpose of this study was to make a comparison between computed tomography (CT) and chest X-ray (CXR) through a scoring system that can be beneficial to the clinicians in making the triage of patients diagnosed with COVID-19 pneumonia at their initial presentation to the hospital. Results Patients with a negative CXR (30.1%) had significantly lower computed tomography score (CTS) (p < 0.001). Among the lung zones where the only infiltration pattern was ground glass opacity (GGO) on CT images, the ratio of abnormality seen on CXRs was 21.6%. The cut-off value of X-ray score (XRS) to distinguish the patients who needed intensive care at follow-up (n = 12) was 6 (AUC = 0.933, 95% CI = 0.886–0.979, 100% sensitivity, 81% specificity). Conclusions Computed tomography is more effective in the diagnosis of COVID-19 pneumonia at the initial presentation due to the ease detection of GGOs. However, a baseline CXR taken after admission to the hospital can be valuable in predicting patients to be monitored in the intensive care units.

Background: Contrast enhanced ultrasound (CEUS) through MicroBubbles Time (MBT) (time from infusion of saline with addition of micro-bubbles of air to visualization of first bubbles in right atrium (RA), visualized by subxiphoid or apical echocardiography) is an alternative to Intracavitary ECG and chest X-ray in evaluation of tip location in central venous catheters. Objective: To evaluate feasibility and variability of CEUS in peripheral catheters (Midline-MC) in a cohort of patients and in a subgroup where tip location was also performed through chest X-ray. Secondary outcomes were verifying the correlation between MBT and distance between tip of MC and RA (anthropometric and radiological measures), body mass index (BMI), vein diameter at point of insertion. Methods: Patients with insertion of MC were enrolled in this prospective cohort. After catheter insertion, CEUS was performed recording MBT. Results: One hundred thirty-two MCs were inserted, 45 performed Chest X-ray. MBT wasn’t feasible in 7 (5%) because of low quality echocardiographic images. Subcostal view was available in 114 patients (91.2%), while 11 patients (8.8%) were examined through apical four-chamber view. Mean MBT in the whole population was 2.3 ± 0.8 s. Significant correlation between anthropometric and radiological measures, BMI and MBT was found. 32.8% of MC had a MBT ⩽2 s. Conclusions: CEUS could be useful to estimate tip position. Our study showed how 2 s is not a suitable cutoff to confirm central catheter’s tip.

Childhood Fever

Many people believe that temperature response to antipyretics in febrile children varies according to diagnosis. To evaluate the validity of this premise, we prospectively studied the temperature response to acetaminophen of febrile children who came to an urban pediatric emergency and walk-in facility. The study group consisted of 1,559 patients between the ages of 8 weeks and 6 years whose temperatures when seen were greater than 38.4°C and who had not received antipyretic treatment within the previous four hours. Acetaminophen (15 mg/kg) was administered to each child and repeat temperatures were taken one and two hours later. Patient management was unaffected by the study, and physicians were unaware of the repeat temperature measurements. Telephone follow-up was conducted with the parents of each child within five days of the initial visit. Children with cultures positive for bacterial disease or chest x-ray films positive for pneumonia had slightly greater one- and two-hour temperature decreases compared with children with other diagnoses. Although statistically significant, we do not consider these differences in response to be clinically useful. We conclude that fever response to acetaminophen is not a clinically useful indicator by which to differentiate the causes of febrile illnesses in young children.
