ABSTRACT

BACKGROUND: Noonan Syndrome is the second most common genetic syndrome associated with congenital heart disease. Many patients with Noonan Syndrome will require a cardiac intervention. This study aimed to characterize the difference in cardiac surgery admissions in patients with and without Noonan Syndrome. METHODS: Data regarding hospital admissions was collected using the Kids' Inpatient Database from 1997 to 2012. A cross-sectional study was conducted comparing baseline characteristics, cardiac morphology, cardiac surgery, and other comorbidities between those with and without Noonan Syndrome. Regression analysis was conducted to determine factors related to Noonan Syndrome and risk factors for increased length of hospitalization, need for ECMO, and inpatient mortality using Noonan Syndrome as the independent variable. RESULTS: A total of 46,169 admissions with cardiac surgery under 18 years of age were included in the final analyses. Of these 778 (1.6%) had Noonan Syndrome. Pulmonary stenosis, coronary anomalies, and valvuloplasty without valve replacement were independently associated with Noonan Syndrome. Those with Noonan Syndrome were 90% more likely to have chylothorax. Pediatric cardiac surgery admissions tended to be 4.5 days longer and cost $54,296 more in total charges with Noonan Syndrome. Inpatient mortality is also increased by Noonan Syndrome. CONCLUSIONS: Noonan Syndrome is present in a relatively small proportion of pediatric cardiac surgery admissions. Noonan Syndrome is independently associated with increased length and cost of such admissions as well as inpatient mortality.

ABSTRACT

BACKGROUND: Vasoactive medications are commonly administered for afterload reduction and arterial hypertension treatment in patients after cardiac surgery. A systematic review and meta-analysis were conducted to determine the effects of sodium nitroprusside and nicardipine on hemodynamics and cardiac performance in this population. METHODS: A systematic review of published manuscripts was performed to identify studies of patients who received sodium nitroprusside and nicardipine as part of the treatment for arterial hypertension or afterload reduction after cardiac surgery. A meta-analysis was then conducted to determine the effects of sodium nitroprusside and nicardipine on hemodynamics and cardiac performance. The following parameters were captured: blood pressure, heart rate, right atrial pressure, systemic vascular resistance, and stroke volume. RESULTS: In total, five studies with 571 patients were pooled for these analyses. Systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were similar in both groups. The cardiac index was greater with nicardipine while mean pulmonary artery pressure was lower with sodium nitroprusside. CONCLUSION: Nicardipine and sodium nitroprusside have similar abilities in reducing afterload in the postoperative cardiac population. Statistically significant differences were found in pulmonary artery pressure and cardiac index. It may be beneficial to consider nicardipine for afterload reduction in patients with a low cardiac index.

ABSTRACT

INTRODUCTION: Adults with congenital heart disease (ACHD) represent a population with unique health-care needs. Many patients require cardiac surgery, with some requiring postoperative extracorporeal membrane oxygenation (ECMO). This study aimed to identify the risk factors for the need of postoperative ECMO and characterize the impact of ECMO on admission characteristics. METHODS: Data from the 2005-2012 iterations of the Nationwide Inpatient Sample were used. ACHD admissions over 18 years with a documented cardiac surgery were included. Univariate analysis was conducted to compare the characteristics between those requiring ECMO and those who did not. Regression analysis was done to identify the independent risk factors associated with ECMO and to determine the impact of ECMO on length, cost, and mortality of the admission. RESULTS: A total of 186,829 admissions were included. Of these, 446 (0.2%) admissions required ECMO. Those with acute kidney injury, double-outlet right ventricle, or total anomalous pulmonary venous connection were more likely to require ECMO. ECMO was also significantly more utilized in patients undergoing septal defect repair, complete repair of tetralogy of Fallot, atrial switch, and heart transplant. The use of ECMO significantly increased length, cost, and mortality of stay. Overall mortality was 62.6% in the ECMO group. CONCLUSION: ECMO is only needed in a small proportion of postoperative ACHD patients. The use of ECMO significantly increases cost, length of stay and mortality in these patients. Improved identification of postoperative ACHD patients who are more likely to survive ECMO may facilitate improved survival and decreased resource utilization.
