Glutamate Infusion Reduces Kidney Injury After Cardiac Surgery: JAMA
A recent study published in the Journal of American Medical Association unveiled promising results regarding the prevention of acute kidney injury (AKI) following cardiac surgery. This study explored the potential benefits of utilizing glutamate infusion during coronary artery bypass graft (CABG) procedures.
Acute kidney injury (AKI) is a serious complication associated with cardiac surgery that contributes to increased morbidity and mortality rates among patients. Despite numerous attempts to reduce this risk, success rate has been limited. Thereby, GLUTAMICS (Glutamate for Metabolic Intervention in Coronary Surgery) study pooled data from two prospective, randomized, double-blind multicenter trials and was conducted across five cardiac surgery centers in Sweden. The trials spanned from 2005 to 2020 and included a total of 791 patients without diabetes who were undergoing CABG surgery.
During the procedure, patients received either intravenous infusion of l-glutamic acid or saline. The results found that patients who received glutamate infusion expressed a significantly lower risk of AKI with a relative risk reduction of 51% when compared to the control group. Also, the need for dialysis post-surgery was significantly lower in the glutamate group.
The study emphasized the importance of these findings by highlighting that glutamate infusion represents a potentially transformative approach to AKI prevention in cardiac surgery patients. While further research is mandated to validate these results, the positive implications for patient care are profound from this research.
Globally, cardiac surgeons and medical professionals are optimistic about the implications of this study. If confirmed in future trials, glutamate infusion could become a standard intervention for patients against AKI during CABG procedures which ultimately improve the patient outcomes and reduce healthcare burdens.
