MATERIALS AND METHODS: Our study used the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020. The literature search approach used publications between 2013 and 2023 using Pubmed and SagePub databases. Studies were included if they contained reports of the best timing for emergency surgery for CHD repair. We did not include review articles and unpublished data.
RESULTS: Five articles met the criteria. The overall result, the first pre-operative 24-hour oxygenation index mean, was temporally reliable and representative (intraclass correlation coefficient = 0.70, 95% CI = 0.61-0.77). Within any severity level, there were no differences in 90-day survival or mortality rate between delayed repair and early repair (p = 0.002). As a result, there is no optimal timing for surgery in severe cases of CDH. A delay in repair did not predict an increased risk of death, nor did it suggest an increased need for post-operative extracorporeal membrane oxygen therapy.
CONCLUSION: Regardless of the severity of the illness, the timing of CDH repair does not affect the mortality rate.Surgery is done after the physiology index achievement.
