Poor growth with underweight for age, decreased length/height for age, and underweight-for-height are all relatively common in children with CHD. The underlying causes of this failure to thrive may be multifactorial, including innate growth potential, severity of cardiac disease, increased energy requirements, decreased nutritional intake, malabsorption, and poor utilisation of absorbed nutrition. These factors are particularly common and severe in low-and middle-income countries.Although nutrition should be carefully assessed in all patients, failure of growth is not a contraindication to surgical repair, and patients should receive surgical repair where indicated as soon as possible.Close attention should be paid to nutritional support -primarily enteral feeding, with particular use of breast milk in infancy -in the perioperative period and in the paediatric ICU. This nutritional support requires specific attention and allocation of resources, including appropriately skilled personnel.Thereafter, it is essential to monitor growth and development and to identify causes for failure to catch-up or grow appropriately.
Postoperative infections contribute to mortality and morbidity after congenital heart surgery. Younger, more complex patients are at particular risk. Quality improvement targeted at infection risk may reduce morbidity and mortality in the developing world.
TOF patients are often operated on after age 1 year in LMICs. Unlike in developed countries, older age is not a risk factor for death. Nutritional and hypoxemic status were associated with higher mortality and infection. This information fills a critical knowledge gap for surgery in LMIC.
Background: Noninvasive respiratory support is often used in preventing postextubation respiratory failure in neonates and infants after cardiac surgery. Aim: We compared the efficacy of nasal Bilevel Positive Airway Pressure (N/BiPAP) with that of High- flow Nasal Cannula(HFNC) in prevention of post extubation respiratory failure and maintenance of gas exchange in neonates and infants undergoing cardiac surgery. The incidence of complications related to the use of these modes were also compared. Settings and Design: This is a retrospective review of medical records of patients in pediatric cardiac intensive unit of a high-volume center. Methods: A total of 100 patients who received noninvasive respiratory support postextubation were divided into N/BiPAP group and HFNC group. The two groups were compared for postextubation respiratory failure, gas exchange in arterial blood gas at 24 h of extubation, and incidence of complications, namely pneumothorax, abdominal distension, and device–interface-related pressure ulcers. Results: Fifty patients each received N/BiPAP and HFNC after extubation. Patients who received N/BiPAP were younger (2.68 ± 2.97 months vs. 6.94 ± 4.04 months, P = 0.001) and had longer duration of postoperative ventilation (106.98 ± 79.02 h vs. 62.72 ± 46.14 h, P = 0.001). The reintubation rates were similar (20% [ n = 10] in N/BiPAP group vs. 8% [ n = 4] in HFNC group, P = 0.074). The mean arterial PO 2 values at 24 h of extubation was 119.17 ± 56.07 mmHg for N/BiPAP group versus 123.32 ± 64.33 mmHg for HFNC group ( P = 0.732). Arterial PCO 2 values at 24 h were similar (43.97 ± 43.64 mmHg in N/BiPAP vs. 37.67 ± 4.78 mmHg in HFNC, P = 0.318). N/BiPAP group had higher incidence of abdominal distension (16% [ n = 8] vs. nil in HFNC group, P = 0.003) and interface-related pressure ulcers (86% [ n = 43] vs. 14% [ n = 7] P = 0.006). Conclusion: N/BiPAP and HFNC have comparable efficacy in preventing reintubation and maintaining gas exchange. HFNC has fewer complications compared to N/BiPAP.
Introduction and Aim:Focussed cardiac intensive care is known to produce better outcomes. We have evaluated the benefits of a dedicated Pediatric Cardiac Intensive Care Unit (PCICU) in the early postoperative outcomes of patients undergoing surgery for congenital heart disease.Methods:Prospectively collected data of 634 consecutive patients who underwent congenital heart surgery from September 2008 to September 2009 were analyzed. Midway through this period a dedicated PCICU was started. The patients who were treated in this new PCICU formed the study group (Group B, n = 318). The patients who were treated in a common postoperative cardiac surgery ICU formed the control group (Group A, n = 316). Early postoperative outcomes between the two groups were compared.Results:The two groups were comparable with respect to demographic data and intraoperative variables. The duration of mechanical ventilation in the dedicated pediatric cardiac ICU group (32.22 ± 52.02 hours) was lower when compared with the combined adult and pediatric surgery ICU group (42.92 ± 74.24 hours, P= 0.04). There was a shorter duration of ICU stay in the dedicated pediatric cardiac ICU group (2.69 ± 2.9 days vs. 3.43 ± 3.80 days, P = 0.001). The study group also showed a shorter duration of inotropic support and duration of invasive lines. The incidence of blood stream infections was also lower in the dedicated pediatric ICU group (5.03 vs. 9.18%, P = 0.04). A subgroup analysis of neonates and infants <1 year showed that the advantages of a dedicated pediatric intensive care unit were more pronounced in this group of patients.Conclusions:Establishment of a dedicated pediatric cardiac intensive care unit has shown better outcomes in terms of earlier extubation, de-intensification, and discharge from the ICU. Blood stream infections were also reduced.
Background:The International Quality Improvement Collaborative (IQIC) for Congenital Heart Surgery in Developing Countries was initiated to decrease mortality and major complications after congenital heart surgery in the developing world.Objective:We sought to assess the impact of IQIC on postoperative outcomes after congenital heart surgery at our institution.Methods:The key components of the IQIC program included creation of a robust worldwide database on key outcome measures and nurse education on quality driven best practices using telemedicine platforms. We evaluated 1702 consecutive patients ≤18 years undergoing congenital heart surgery in our institute from January 2010-December 2012 using the IQIC database. Preoperative variables included age, gender, weight at surgery and surgical complexity as per the RACHS-1 model. The outcome variables included, in- hospital mortality, duration of ventilation, intensive care unit (ICU) stay, bacterial sepsis and surgical site infection.Results:The 1702 patients included 771(45.3%) females. The median age was 8 months (0.03-216) and the median weight was 6.1Kg (1-100). The overall in-hospital mortality was 3.1%, Over the three years there was a significant decline in bacterial sepsis (from 15.1%, to 9.6%, P < 0.001), surgical site infection (11.1% to 2.4%, P < 0.001) and duration of ICU stay from 114(8-999) hours to 72 (18-999) hours (P < 0.001) The decline in mortality from (4.3% to 2.2%) did not reach statistical significance.Conclusions:The inclusion of our institution in the IQIC program was associated with improvement in key outcome measures following congenital heart surgery over a three year period.
Objective:To study the impact of red cell distribution width (RDW) on postoperative recovery after correction of Tetralogy of Fallot (TOF).Background:Increased RDW indicates dysregulated erythropoiesis and predicts survival in critical illnesses that include idiopathic pulmonary artery hypertension and chronic heart failure. Myocardial injury and oxidative stress induced by cardiopulmonary bypass potentially contribute to prolonged recovery in post TOF repair patients.Materials and Methods:Retrospective analysis of data on 94 consecutive children with TOF undergoing corrective repair (January 2010-March 2011) was done. RDW was higher for the study population when compared to acyanotic patients with ventricular septal defect (17.7 ± 3.7 vs. 16.2 ± 4.2; P < 0.001). The mean RDW obtained from 100 separate age-, sex-, and weight-matched TOF patients (17.8) was chosen as a cut-off. Of 93 survivors (median age: 12 (4-204) months, weight: 8.6 (3.2-70) kg), 29 patients with higher RDW (> 17.8) had a longer ICU stay (155.6 ± 71.3 vs. 122.4 ± 61.3 hours, P = 0.02), hospital stay (18.6 ± 10.5 days vs. 13.4 ± 6.5 days, P = 0.01), ventilation time (57.9 ± 41.6 vs. 38.3 ± 30.8 hours, P = 0.01), and more surgical site infection (24.1% vs. 6.2%, P = 0.01). On multivariate analysis only elevated RDW (other variables included age, weight, hemoglobin, hematocrit, and surgical support times) showed a significant association with hospital stay.Conclusions:Elevated RDW appears to be associated with prolonged recovery after TOF repair, the precise underlying mechanisms are worth investigating.
