Parasternal blockade has been related to a reduction of the postoperative inflammatory response, by inhibition of the stress response, leading to a better prognosis. Increased lactate level is a useful parameter in identifying patients at risk of postoperative morbidity and mortality. The objective was to evaluate the association between parasternal blockade and serum lactate level in patients undergoing cardiac surgery, both trans- and post-anesthesia. 86 patients between 60-70 years of age participated. An association was found between the application of parasternal blockade in cardiac surgery and the presence of lower trans and postanesthetic serum lactate levels.
An analytical cross-sectional study in adult patients who underwent elective cardiac surgery. A total sample of 86 patients was obtained, 43 in the case group and 43 in the control group. Adult patients older than 18 years, of either sex, with ASA II-III, patients who underwent cardiac surgery with median sternotomy and use of cardiopulmonary bypass were included.
