Parasternal Blockade and Serum Lactate in Cardiac Surgery

Not Applicable

Recruiting

• Conditions: Elective Cardiac Surgery
• Interventions: Procedure: Parasternal block; Procedure: Requirement of total dose regarding fentanyl

• Registration Number: NCT06516432
• Lead Sponsor: Instituto Mexicano del Seguro Social

Brief Summary

Serum lactate level is a key indicator of tissue perfusion. Parasternal blockade is associated with reduced postoperative inflammatory response by inhibiting stress response, leading to better outcomes. Elevated lactate levels help identify patients at risk of postoperative morbidity and mortality. This analytical cross-sectional study evaluated the association between parasternal blockade and serum lactate levels in patients undergoing elective cardiac surgery in 2022 at Specialty Hospital CMNO. Patients with and without parasternal block were compared for changes in serum lactate levels during and after anesthesia within the first 24 hours.

Detailed Description

Background: Serum lactate level is a crucial indicator of tissue perfusion. 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 the identification of patients at risk of postoperative morbidity and mortality.

Objective: To evaluate the association between parasternal blockade and serum lactate level in patients undergoing cardiac surgery, both trans and postanesthesia.

Materials and Methods: Analytical cross-sectional study in adult patients undergoing elective cardiac surgery during the year 2022 in Specialty Hospital CMNO, patients with and without application of parasternal block were analyzed, and it was associated with changes in serum lactate level trans and post anesthesia in the first 24 hours. Approval registration: R-2023-1301-024.
