Abstract
This study evaluated practices for image guidance during placement of bicaval dual-lumen (BCDL) venovenous extracorporeal membrane oxygenation (VV-ECMO) cannulas in pediatric and adolescent patients and elucidates reasoning behind surgeon practices. A survey covering VV-ECMO practice and opinions was distributed by the American Pediatric Surgical Association (APSA) to all attending members. A total of 110 pediatric surgeons responded (11.3%). During initial BCDL cannula placement, 67.7% of surgeons reported using bimodal imaging with either fluoroscopy (38.4%) or x-ray (29.3%) plus echocardiography. Although 37.4% of surgeons used serial x-rays during cannula placement, only 5.9% believed it was best practice to do so ( P < 0.0001). Rather, 60.4% believed that fluoroscopy was the standard. Among surgeons not using fluoroscopy, 27.6% (13.3% of respondents) reported fluoroscopy added unnecessary complexity or that they preferred another modality. More frequently, reasons for not using fluoroscopy are related to resource limitations. Echocardiography use to confirm cannula position was considered best practice by 92.1% of surgeons, with 86.9% utilization. Therefore, most pediatric surgeons use multimodal imaging during cannulation and consider it best practice. Fluoroscopy is preferred, but its use is frequently limited by hospital resources. Echocardiography is widely available and used. These data represent increased consensus among surgeons and present opportunities for modernization of hospital resources and standards.

Abstract
BACKGROUND We analyzed the use of Extracorporeal Membranous Oxygenation (ECMO) in acute care surgery patients at our Level-1 trauma center. We hypothesized that this patient population has improved ECMO outcomes. METHODS This was a retrospective analysis of emergency general surgery and trauma patients placed on ECMO between the periods of October 2013 and February 2020. There were 10 surgical and 12 trauma patients studied, who eventually required ECMO support. ECMO support and ECMO type/modality were analyzed with injury and survival prognostic scores examined. MAIN RESULTS Overall, 16 of the 22 patients survived to hospital discharge, for a survival rate of 73%. Mean age was 34.18 years. Mean hospital length of stay was 23.4 days with mean days on ECMO equal to 7.5. The net negative fluid balance was 5.36 L. CONCLUSIONS The survival of our ECMO cohort is notably higher than previously cited studies. Our group demonstrated decreased length of time on ECMO, decreased length of stay in the hospital, and similar rates of complications compared to prior reports. ECMO is a useful modality in acute care surgical patients and should be considered in these patient populations. Our focus on net negative fluid balance for ECMO patients demonstrates improved survival. ECMO should be considered early in surgical patients and early in advanced trauma life support.

Abstract
BACKGROUND Transthoracic echocardiography (TTE) plays a fundamental role in the management of patients supported with extra-corporeal membrane oxygenation (ECMO). In light of fluctuating clinical states, serial monitoring of cardiac function is required. Formal quantification of ventricular parameters and myocardial mechanics offer benefit over qualitative assessment. The aim of this research was to compare unenhanced (UE) versus contrast-enhanced (CE) quantification of myocardial function and mechanics during ECMO in a validated ovine model. METHODS Twenty-four sheep were commenced on peripheral veno-venous ECMO. Acute smoke-induced lung injury was induced in 21 sheep (3 controls). CE-TTE with Definity using Cadence Pulse Sequencing was performed. Two readers performed image analysis with TomTec Arena. End diastolic area (EDA, cm2), end systolic area (ESA, cm2), fractional area change (FAC, %), endocardial global circumferential strain (EGCS, %), myocardial global circumferential strain (MGCS, %), endocardial rotation (ER, degrees) and global radial strain (GRD, %) were evaluated for UE-TTE and CE-TTE. RESULTS Full data sets are available in 22 sheep (92%). Mean CE EDA and ESA were significantly larger than in unenhanced images. Mean FAC was almost identical between the two techniques. There was no significant difference between UE and CE EGCS, MGCS and ER. There was significant difference in GRS between imaging techniques. Unenhanced inter-observer variability was from 0.48-0.70 but significantly improved to 0.71-0.89 for contrast imaging in all echocardiographic parameters. CONCLUSION Semi-automated methods of myocardial function and mechanics using CE-TTE during ECMO was feasible and similar to UE-TTE for all parameters except ventricular areas and global radial strain. Addition of contrast significantly decreased inter-observer variability of all measurements.

Abstract
Indications for extracorporeal membrane oxygenation (ECMO) and extracorporeal cardiopulmonary resuscitation (ECPR) are expanding, and echocardiography is a tool of utmost importance to assess safety, effectiveness and readiness for circuit initiation and separation. Echocardiography is key to anticipating complications and improving outcomes. Understanding the patient's as well as the ECMO circuit's anatomy and physiology is crucial prior to any ECMO echocardiographic evaluation. It is also vital to acknowledge that the utility of echocardiography in ECMO patients is not limited to the evaluation of cardiac function, and that clinical decisions should not be made exclusively upon echocardiographic findings. Though echocardiography has specific indications and applications, it also has limitations, characterized as: prior to and during cannulation, throughout the ECMO run, upon separation and after separation from the circuit. The use of specific and consistent echocardiographic protocols for patients on ECMO is recommended.

Abstract
BACKGROUND Transthoracic echocardiography (TTE) during extra corporeal membrane oxygenation (ECMO) is important but can be technically challenging. Contrast-specific TTE can improve imaging in suboptimal studies. These contrast microspheres are hydrodynamically labile structures. This study assessed the feasibility of contrast echocardiography (CE) during venovenous (VV) ECMO in a validated ovine model. METHOD Twenty-four sheep were commenced on VV ECMO. Parasternal long-axis (Plax) and short-axis (Psax) views were obtained pre- and postcontrast while on VV ECMO. Endocardial definition scores (EDS) per segment were graded: 1 = good, 2 = suboptimal 3 = not seen. Endocardial border definition score index (EBDSI) was calculated for each view. Endocardial length (EL) in the Plax view for the left ventricle (LV) and right ventricle (RV) was measured. RESULTS Summation EDS data for the LV and RV for unenhanced TTE (UE) versus CE TTE imaging: EDS 1 = 289 versus 346, EDS 2 = 38 versus 10, EDS 3 = 33 versus 4, respectively. Wilcoxon matched-pairs rank-sign tests showed a significant ranking difference (improvement) pre- and postcontrast for the LV (P < 0.0001), RV (P < 0.0001) and combined ventricular data (P < 0.0001). EBDSI for CE TTE was significantly lower than UE TTE for the LV (1.05 ± 0.17 vs. 1.22 ± 0.38, P = 0.0004) and RV (1.06 ± 0.22 vs. 1.42 ± 0.47, P = 0.0.0006) respectively. Visualized EL was significantly longer in CE versus UE for both the LV (58.6 ± 11.0 mm vs. 47.4 ± 11.7 mm, P < 0.0001) and the RV (52.3 ± 8.6 mm vs. 36.0 ± 13.1 mm, P < 0.0001), respectively. CONCLUSIONS Despite exposure to destructive hydrodynamic forces, CE is a feasible technique in an ovine ECMO model. CE results in significantly improved EDS and increased EL.

A novel echocardiographic imaging technique, intracatheter echocardiography, to guide veno-venous extracorporeal membrane oxygenation cannulae placement in a validated ovine model. Intensive Care Med Exp 2014; 2:2.

Abstract
Background Echocardiography plays a fundamental role in cannulae insertion and positioning for extracorporeal membrane oxygenation (ECMO). Optimal access and return cannulae orientation is required to prevent recirculation. The aim of this study was to compare a novel imaging technique, intracatheter echocardiography (iCATHe), with conventional intracardiac echocardiography (ICE) to guide placement of ECMO access and return venous cannulae. Methods Twenty sheep were commenced on veno-venous ECMO (VV ECMO). Access and return ECMO cannulae were positioned using an ICE-guided technique. Following the assessment of cannulae position, the ICE probe was then introduced inside the cannulae, noting location of the tip. After 24 h, the sheep were euthanized and cannulae position was determined at post mortem. The two-tailed McNemar test was used to compare iCATHe with ICE cannulae positioning. Results ICE and iCATHe imaging was possible in all 20 sheep commenced on ECMO. There was no significant difference between the two methods in assessing access cannula position (proportion correct for each 90%, incorrect 10%). However, there was a significant difference between ICE and iCATHe success rates for the return cannula (p = 0.001). Proportion correct for iCATHe and ICE was 80% and 15% respectively. iCATHe was 65% more successful (95% CI 27% to 75%) at predicting the placement of the return cannula. There were no complications related to the ICE or iCATHe imaging. Conclusion iCATHe is a safe and feasible imaging technique to guide real-time VV ECMO cannulae placement and improves accuracy of return cannula positioning compared to ICE.
