This study found no significant difference in neurological function after coronary revascularization across different perfusate temperatures. Maintaining normal neurological function is key, regardless of temperature interventions.

Area of Science:

  • Cardiovascular Surgery
  • Neurology
  • Medical Research

Background:

  • Systemic perfusate temperature is a variable during coronary revascularization.
  • The impact of varying perfusate temperatures on neurological function requires further investigation.

Purpose of the Study:

  • To investigate the influence of different perfusate temperatures on neurological function in patients undergoing coronary revascularization.
  • To compare neurological outcomes at warm (37°C), tepid (32°C), and cold (20°C) perfusate temperatures.

Main Methods:

  • A randomized trial involving 51 patients undergoing coronary revascularization.
  • Patients were assigned to warm, tepid, or cold systemic perfusate and cardioplegia temperatures.
  • Neurological function was assessed using the Mathew Scale preoperatively, at discharge, and at 1-month follow-up.

Main Results:

  • A significant decrease in neurological function was observed from preoperative to postoperative assessments across all groups (p < 0.05).
  • This neurological deficit resolved by the 1-month follow-up.
  • No statistically significant differences in neurological function were found between the warm, tepid, and cold temperature groups.

Conclusions:

  • Perfusate temperature during coronary revascularization did not demonstrate a discernible influence on neurological function in this study.
  • Further research with additional patients is warranted to confirm these findings.
