Summary

This summary is machine-generated.

Off-pump coronary artery bypass graft surgery can cause early endothelial glycocalyx layer (EGL) shedding, increasing the risk of systemic inflammation response syndrome (SIRS). Sevoflurane anesthesia did not show a significant advantage over propofol in preserving EGL during OPCABG.

Area Of Science

  • Cardiovascular Surgery
  • Anesthesiology
  • Inflammation Biology

Background

  • Off-pump coronary artery bypass graft (OPCABG) surgery is associated with a high incidence of postoperative systemic inflammation response syndrome (SIRS).
  • Perioperative disruption of the endothelial glycocalyx layer (EGL) is a potential predisposing factor for SIRS after OPCABG.
  • This study investigates the timing of EGL shedding during OPCABG and its impact on postoperative SIRS, comparing sevoflurane and propofol anesthesia.

Purpose Of The Study

  • To determine if EGL shedding occurs earlier during OPCABG and influences postoperative SIRS.
  • To compare the EGL-preserving effects of sevoflurane versus propofol anesthesia during OPCABG.
  • To analyze the correlation between EGL markers, inflammatory markers, and clinical outcomes.

Main Methods

  • A randomized trial involving 50 patients undergoing OPCABG, assigned to sevoflurane-sufentanil or propofol-sufentanil anesthesia.
  • Measurement of plasma syndecan-1, heparan sulfate (HS), atrial natriuretic peptide (ANP), IL-6, and cardiac troponin I (cTnI) at six time points.
  • Assessment of SIRS criteria and Sequential Organ Failure Assessment (SOFA) scores.

Main Results

  • No significant differences in syndecan-1, HS, IL-6, SIRS criteria, or SOFA scores were observed between the sevoflurane and propofol groups.
  • Pooled analysis revealed significant increases in plasma syndecan-1 and IL-6 over time.
  • Syndecan-1 levels correlated with graft anastomosis duration, ANP, and IL-6; IL-6 and SOFA scores correlated with SIRS, ICU days, and occurrence of SIRS.

Conclusions

  • Early EGL shedding during OPCABG, particularly during graft anastomosis, significantly impacts postoperative SIRS and SOFA scores.
  • Sevoflurane anesthesia did not demonstrate a clinical advantage in preserving the EGL compared to propofol.
  • The findings highlight the role of EGL integrity in mitigating inflammatory responses following OPCABG.
