Brief Summary

Introduction: Glutamine (GLN) is the most abundant free amino acid in the body. It modulates immune cell function and is an important energy substrate for most cells (especially for enterocytes and lymphocytes) in critical patients. GLN levels significantly decreased during sepsis/critical illness leading to an increase in infectious complications, organ failure and mortality. Moreover, in cases of ischemia/reperfusion injury in the myocardium, GLN increases the levels of Adenosine triphosphate (ATP)/Adenosine diphosphate (ADP) ratio and prevents intracellular lactate accumulation. Recently, the perioperative effect of intravenous and oral GLN treatment been associated in lowering levels of cardiac injury markers such as Troponin-I (TROP-I) and the number of postoperative complications in patients who underwent Cardiopulmonary Bypass (CPB). The aim of the study was to analyze the oral dose of preoperative oral GLN treatment in patients who underwent CPB with extracorporeal circulation in Mexican patients.

Study Arms (2)

GLN group

ACTIVE COMPARATOR

All patients in the GLN group received an oral GLN supplement. The total GLN dose given to patients was standardized to 0.5 g/kg/day during 3 days prior to CPB, and one final dose of 0.25 g/kg/day of GLN/maltodextrin in the morning of surgery 4 hours prior to initiation of anesthesia.

Dietary Supplement: Supplement/placebo intake

CONT group

PLACEBO COMPARATOR

All patients in the GLN group received an oral maltodextrin supplement, similar in shape and texture as GLN supplement. The total placebo given to patients was standardized to 0.5 g/kg/day during 3 days prior to CPB, and one final dose of 0.25 g/kg/day of maltodextrin in the morning of surgery 4 hours prior to initiation of anesthesia.

Dietary Supplement: Supplement/placebo intake

Interventions

Supplement/placebo intakeDIETARY_SUPPLEMENT

Patients will receive either GLN or placebo prior to cardiovascular surgery under extracorporeal circulation, during 3 days and one final dose 4 hours prior to anesthesia.
