Brief Summary

Omega-3 polyunsaturated fatty acids (w-3-PUFA) may have a potential role in enhance the postoperative balance of host immunity and reduce the incidence of postoperative atrial fibrillation (POAF). CHO drinks 2h before the induction of the anesthesia may reduce the necessity of vasoactive drugs preoperatively. the aim of this study was to investigate the effect of these two nutrients in patients undergoing CABG with cardiopulmonary bypass (CPB) on morbidity at ICU, mainly POFA. This is a double-blind controlled randomized trial.

Outcome Measures

Primary Outcomes (2)

  • The incidence of postoperative atrial fibrillation (POAF)

    categorical data (patients either had or not had POAF

    48 hours

  • The need of inotropic vasoactive drug (dobutamine and/or noradrenalin) for weaning from cardiopulmonary bypass (intraoperative period) and at ICU (postoperative period).

    categorical data (patients either need or not need vasoactive drug

    48 hours

Secondary Outcomes (4)

  • Postoperative morbidity

    the incidence of morbidity up to 30 days after surgery

  • Length of both ICU stay

    number of days up to 30 days postoperatively

  • Postoperative mortality

    the incidence of mortality up to 30 days after surgery

  • Length of both hospital stay

    number of days in hospital up to 30 days postoperatively

Study Arms (4)

CHO (carbohydrate) group

EXPERIMENTAL

Patients received a 8h preoperative fast for solids and 2h fast with 200mL of a drink containing water plus 12.5% maltodextrin (25g) and no infusion of intraoperative w-3-PUFA

Dietary Supplement: CHO (carbohydrate)

W-3 PUFA group

EXPERIMENTAL

Patients received preoperative fast for solids but allowed to drink 200 mL of water until 2h before anesthesia, and an intravenous intraoperative dose of intravenous w-3-PUFA (0.2 mcg/kg)

Drug: intravenous w-3 PUFA

CHO plus intravenous w3-PUFA group

EXPERIMENTAL

Patients received a 8h fast for solids and 2h fast with 200mL of a drink containing water plus 12.5% maltodextrin (25g), and an intravenous intraoperative dose of intravenous w-3-PUFA (0.2 mcg/kg)

Other: CHO (carbohydrate) plus intravenous w3-PUFA

Control

NO INTERVENTION

Patients received preoperative fast for solids for 8h but allowed to drink 200 mL of water until 2h before anesthesia; and no infusion of intraoperative intravenous w-3-PUFA

Interventions

CHO plus intravenous w3-PUFA group

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The authors include all patients of both sexes with medical diagnose of chronic coronary heart disease and eligible to elective coronary artery bypass grafting (CABG)

You may not qualify if:

  • The investigators exclude those who have insulin-dependent diabetic, hepatic or renal disorders, thrombocytopenia, important dyslipidemia (triglycerides 3-fold higher than normal standard), gastro-esophageal reflux, acute coronary syndromes, allergy to fish oil, and severe malnutrition. We also exclude patients underwent off-pump CABG, combined heart procedures, reoperations, and those who received blood transfusion in the last 3 months.
