Objective: To compare the cost of using intravenous epoprostenol with that of inhaled nitric oxide (NO) for treating episodes of pulmonary hypertension in children with congenital heart disease. Design: An analysis of the cost of epoprostenol and NO use over the previous 18 months was performed. Three 6-month periods were identified, two in which epoprostenol was used and the third in which inhaled NO was introduced for the treatment of pulmonary hypertension. Setting: A 10-bed pediatric cardiac intensive care unit, Royal Liverpool Children's Hospital, Alder Hey, Liverpool, England. Subjects: Children with congenital heart disease and persistently elevated pulmonary artery pressure following cardiac surgery. Main Outcome Measures: The total duration of use of epoprostenol and inhaled NO was documented. The costs per hour for epoprostenol and inhaled NO were calculated and the annual cost of each agent was estimated. Results: In the two 6-month periods prior to the introduction of inhaled NO, epoprostenol was used on 14 occasions (5 in the first period, 3 in the second). In the last 6-month period, nine children required pulmonary vasodilator therapy on 14 occasions. All nine children were treated successfully with inhaled NO; none were given or needed epoprostenol, as NO always was effective in providing pulmonary vasodilatation. For resistant pulmonary hypertension, increasing the concentration of NO would have been the next therapeutic option. The cost for the two 6-month periods using epoprostenol was $19,483.48 for the drug and $283.25 for equipment costs (total cost $19,766.73). There was no expenditure on epoprostenol in the final 6-month period. The cost of NO was $465. However, the total expenditure, including the delivery and monitoring system, was $4,722.85. Conclusions: Using inhaled NO in our pediatric cardiac intensive care unit abolished the use of epoprostenol during the reported monitoring period. The cost savings were significant, amounting to 12% of the annual drug budget for the unit. The cost of setting up the inhaled NO delivery system is recouped rapidly. The ease of delivery and measurement of inhaled NO also may have contributed to its increased clinical use.

Background: Recently it has been apprehended that sildenafil, a drug which has been successfully using in the treatment of PPHN and erectile dysfunction in adult, is going to be withdrawn from the market of Bangladesh due to threat of its misuses. Objective: The aim of this study was to see the extent of uses of sildenafil in the treatment of PPHN and importance of availability of this drugs in the market inspite of its probable misuses. Methods: This cross sectional study was conducted in neonatal intensive care unit (NICU), special baby care unit (SCABU) and cardiac intensive care unit (CICU) of Dhaka Shishu (Children) Hospital from June, 2017 to May 2018. Neonates with PPHN were enrolled in the study. All cases were treated with oral sildenefil for PPHN along with others management according to hospital protocol. Data along with other parameters were collected and analyzed. Results: Total 320 patients with suspected PPHN were admitted during the study period. Among them 92 (29%) cases had PPHN. Male were 49(53 %) cases and female were 43(47%) cases. Mean age at hospital admission was 29.7±13.4 hours. Based on echocardiography,13(14%) cases had mild, 38 (41%) cases moderate and 41(45%) cases severe PPHN. Mean duration of sildenafil therapy was 11.9±7.1 days. Improved from PPHN were 83 (90%) cases. Mortality was 10% (9). Conclusion: In this study it was found that the incidence of PPHN is 29% among the suspected newborns. Sildenafil is successfull in improving the oxygenation of PPHN and to decrease the mortality of neonates. DS (Child) H J 2019; 35(2) : 100-104

Abstract Background Hyperoxia produces reactive oxygen species, apoptosis, and vasoconstriction, and is associated with adverse outcomes in patients with heart failure and cardiac arrest. Our aim was to evaluate the association between hyperoxia and mortality in patients (pts) receiving positive pressure ventilation (PPV) in the cardiac intensive care unit (CICU). Methods Patients admitted to our medical center CICU who received any PPV (invasive or non-invasive) from 2001 through 2012 were included. Hyperoxia was defined as time-weighted mean of PaO2 >120mmHg and non-hyperoxia as PaO2 ≤120mmHg during CICU admission. Primary outcome was in-hospital mortality. Multivariable logistic regression was used to assess the association between hyperoxia and in-hospital mortality adjusted for age, female sex, Oxford Acute Severity of Illness Score, creatinine, lactate, pH, PaO2/FiO2 ratio, PCO2, PEEP, and estimated time spent on PEEP. Results Among 1493 patients, hyperoxia (median PaO2 147mmHg) during the CICU admission was observed in 702 (47.0%) pts. In-hospital mortality was 29.7% in the non-hyperoxia group and 33.9% in the hyperoxia group ((log rank test, p=0.0282, see figure). Using multivariable logistic regression, hyperoxia was independently associated with in-hospital mortality (OR 1.507, 95% CI 1.311–2.001, p=0.00508). Post-hoc analysis with PaO2 as a continuous variable was consistent with the primary analysis (OR 1.053 per 10mmHg increase in PaO2, 95% CI 1.024–1.082, p=0.0002). Conclusions In a large CICU cohort, hyperoxia was associated with increased mortality. Trials of titration of supplemental oxygen across the full spectrum of critically ill cardiac patients are warranted. Funding Acknowledgement Type of funding source: None
