A retrospective cohort of 142 patients undergoing isolated CABG between January 2023 and June 2024 was analyzed. Patients were divided into two groups: Group 1 (n = 71) received 200 mL of chilled mineral water within two hours after extubation; Group 2 (n = 71) received standard hydration. Primary outcomes included antiemetic requirement, oral fluid tolerance, and time to first flatus. Secondary outcomes were serum electrolyte changes, atrial fibrillation incidence, and ICU length of stay.Results: Groups were comparable in demographics. Antiemetic requirement was lower in the mineral water group (21.1% vs. 71.8%, p KW - Coronary artery bypass grafting KW - Postoperative care KW - Mineral water N2 - Giriş: Postoperatif oral hidrasyon sıvı–elektrolit dengesini ve gastrointestinal iyileşmeyi destekler; ancak kardiyak cerrahi hastaları için standartlaştırılmış beslenme kılavuzları bulunmamaktadır.Yöntemler: Bu çalışmada, koroner arter bypass greftleme (CABG) sonrası erken dönemde oral maden suyu verilmesinin gastrointestinal tolerans, elektrolit dengesi ve klinik sonuçlar üzerine etkileri değerlendirildi. Ocak 2023 – Haziran 2024 tarihleri arasında izole CABG uygulanan 142 hasta retrospektif olarak incelendi. Hastalar iki gruba ayrıldı: Grup 1 (n = 71) ekstübasyondan sonraki iki saat içinde 200 mL soğutulmuş maden suyu aldı; Grup 2 (n = 71) ise standart hidrasyon uygulandı. Birincil sonlanım noktaları antiemetik gereksinimi, oral sıvı toleransı ve ilk gaz çıkarma süresiydi. İkincil sonlanım noktaları serum elektrolit değişiklikleri, atriyal fibrilasyon insidansı ve yoğun bakımda kalış süresiydi.Bulgular: Gruplar demografik olarak benzerdi. Antiemetik gereksinimi maden suyu grubunda daha düşüktü (% 21,1’e karşı %71,8; p CR - Aggarwal M, Aggarwal B, Rao J. Integrative medicine for cardiovascular disease and prevention.
