Standardized Perioperative Feeding Protocol Improves Outcomes in Patients With d-Transposition of the Great Arteries Undergoing Arterial Switch Operation.

OBJECTIVE: To determine whether the presence of a standardized feeding protocol improves outcomes in a subset of neonates undergoing cardiac surgery. DESIGN: Retrospective cohort study. SETTING: Cardiovascular ICU at a freestanding academic children's hospital. PATIENTS: Neonates with a diagnosis of d-transposition of the great arteries undergoing arterial switch operation from January 2007 to June 2017. INTERVENTIONS: Initiation of perioperative feeding protocols. MEASUREMENTS AND MAIN RESULTS: Patients were evaluated before and after implementation of standardized perioperative feeding protocols in neonates with d-transposition of the great arteries undergoing arterial switch operation. Low-risk patients born after initiation of nurse-driven protocols were compared with a similar historical group. Data obtained included time to achievement of feeding goals, with primary outcome being weight gain at hospital discharge. Other measures analyzed included duration of mechanical ventilation and postoperative hospital length of stay. Overall, 33 patients in the protocol group were compared with 44 patients in the historical group. No significant baseline differences existed between the two cohorts. The protocol group achieved improved feeding outcomes in nearly all measured categories, including introduction to enteral feeds preoperatively (91% vs 59%; p < 0.01) and earlier attainment of postoperative full enteral feeds of 120 mL/kg/d (2 vs 5 d; p < 0.01). Protocol patients had significantly improved weight gain at the time of discharge (60 vs 1 g; p < 0.01), while achieving shorter postoperative length of stay (10.1 vs 12.6 d; p = 0.04). CONCLUSIONS: An aggressive, but safe, perioperative feeding protocol implemented in a homogenous low-risk neonatal cardiac surgical population improves feeding outcomes, including increased weight gain, as well as decreased postoperative length of stay. Consideration for perioperative feeding protocol implementation and further study should be given.

Comparison of PLANE Technique versus Standard Echocardiography Guidance for Pediatric Pericardiocentesis.

Percutaneous pericardiocentesis remains a challenging and potentially dangerous procedure, particularly in small, critically ill patients. We present outcomes of the PLANE (pericardiocentesis using long-axis in-plane real-time echocardiography) technique for pediatric pericardiocentesis compared with a standard echocardiography (ECHO) guidance cohort. This was a retrospective chart review of all children undergoing percutaneous pericardiocentesis from March 2013 to February 2021 at a single center. A total of 78 procedures were performed, 52 utilizing PLANE technique and 26 utilizing standard ECHO-guidance technique. There was 100% technical success rate with only one minor complication for the entire cohort. Procedures were evenly split between the bedside intensive care unit and cardiac catheterization laboratory. PLANE technique was utilized in significantly younger (1.4 vs. 8.4 years, p = 0.008) and smaller (11.1 vs. 31.8 kg, p = 0.007) patients, as well as in most patients deemed high risk (postoperative < 7 days, extracorporeal membrane oxygenation (ECMO) support, and/or weight less than 5 kg; 19/22, p = 0.021). Other patient characteristics were similar between the two groups. There was a trend toward PLANE technique utilization by noncardiology trained operators. The PLANE technique for pediatric pericardiocentesis is safe and effective and can be effectively utilized in small and high-risk patient populations. The technical similarity to other long-axis ultrasound-guided procedures may facilitate adoption and mastery by critical care trained operators.
