Brief summary
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.
Detailed description
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.
Interventions
PROCEDUREparasternal block
Administration of parasternal block with ropivacaine, bilaterally at the sternum before the start of surgery.
DIAGNOSTIC_TESTLactate serum level
Blood samples were taken to identify serum lactate levels greater than 2 mmol/l and those that remained below this limit.

Intervention model description
Patients were classified as a group of cases with parasternal blockade and as a group of controls without parasternal blockade, with a ratio of cases to controls of 1:1. In the case-control groups, patients with elevated serum lactate levels greater than 2 mmol/L and those who remained below this limit were identified.
