Introduction Antimicrobial prophylaxis, involving short antibiotic courses preceding surgical procedures, is recommended to minimize postoperative infections. Paediatric cardiac surgeries are classified as clean procedures, though infection challenges persist due to illness severity and extended ICU stays. Antimicrobial prophylaxis varies, ranging from single doses to extended administration until catheters are removed. Typically lasting 24 to 48 hours, it has proven infection-reduction benefits. Despite these practices, uncertainties surround the optimal nature, timing, and duration of administration. This concern is amplified by escalating antimicrobial resistance driven by antibiotic overuse. Vulnerable paediatric populations bear heightened consequences of irrational antimicrobial use, contributing to global resistance trends. Yet, a defined optimal prophylaxis schedule for paediatric cardiac surgery is lacking. Importing adult guidelines may be inadequate due to paediatric research complexities and population diversity. Developing effective prophylaxis protocols is crucial for children undergoing cardiac surgery, given global antibiotic overuse and evolving drug resistance. Establishing an optimal prophylactic strategy remains a challenge, necessitating further research for evidence-based protocols to mitigate infections in this vulnerable patient cohort. Methods This study investigates antibiotic use in paediatric cardiac surgery. A retrospective analysis of 100 patients from a rural Indian hospital (2017-2018) assesses antibiotic patterns, including type, dose, duration, and adherence to prophylaxis protocols. Results In the studied cohort of paediatric cardiac surgery patients, complete compliance (100%) with antibiotic prophylaxis was observed. However, deviations were identified: 30% received antibiotics prematurely, and 30% did not align with institutional protocol criteria. Concerning antibiotic selection, 87% followed hospital policy with the recommended cefoperazone and sulbactam combination plus amikacin, while 9% received piperacillin/tazobactam + amikacin due to sepsis. Irregular use (22%) based on clinical records occurred. Furthermore, 4% received piperacillin/tazobactam + teicoplanin, with one instance of inappropriate higher antibiotic use. Regarding prophylaxis duration, only 27% adhered to the appropriate timeline, with 40% exceeding 48 hours, indicating extended use. Upon discharge, a notable proportion (45 patients) received antibiotic prescriptions. Among them, 73% were prescribed rationally, while 27% exhibited irrational antibiotic use. Conclusion The findings of this study shed a significant light on the issue of antibiotic misuse within the context of paediatric cardiac surgery. It underscores the pressing need for more stringent measures to regulate and address this concerning trend. The study underscores the pivotal importance of adhering rigorously to established protocols and guidelines for antibiotic prophylaxis. This adherence not only holds the potential to elevate the overall quality of patient care but also plays a critical role in combating the escalating challenge of antibiotic resistance. Through a concerted effort to optimize antibiotic usage, we can simultaneously enhance patient outcomes and contribute to the ongoing fight against the emergence of antibiotic-resistant strains, thus preserving the efficacy of these vital medications for future generations.
