Abstract
SANTIAGO-LOPEZ, Janaí; LEON-RAMIREZ, Víctor and GUTIERREZ-SANCHEZ, David Guillermo. Clinical trial: effect of magnesium sulfate on serum levels of lactate in the coronary sinus. Rev. mex. anestesiol. [online]. 2022, vol.45, n.2, pp.87-91. Epub Aug 29, 2022. ISSN 0484-7903. https://doi.org/10.35366/103882.
Introduction:
Several methods have been proposed to control inflammation and to preserve the myocardium during cardiopulmonary bypass (CABG), including the administration of electrolytes such as magnesium (Mg2+).
Objective:
To compare the effect of using magnesium sulfate (MgSO4) or a placebo before aortic clamping (AoC) on the serum levels of lactate in the coronary sinus in patients undergoing myocardial multivessel revascularization (MRV) with CABG.
Material and methods:
A clinical assay was conducted with 52 patients undergoing MRV multivessel with CEC; the patients were randomized to receive a placebo (group I) or MgSO4 (group II) before AoC, and blood samples were taken from the coronary sinus to quantify serum lactate at two different times: T0: pre-AoC and T1: before closing the chest. Statistical analysis was performed on Student’s t-test and χ2. A p < 0.05 was considered statistically significant. The data were processed with SPSS v-22.0.
Results:
Serum levels of lactate in the coronary sinus post-AoC were lower in group II (2.967 ± 0.86 vs 2.154 ± 1.14), with significant differences (p = 0.006).
Conclusion:
The use of MgSO4 before AoC reduces serum lactate levels in the coronary sinus in patients undergoing MRV multivessel with CABG.
