Key result
Hypertensive patients undergoing off-pump coronary surgery required significantly higher intraoperative remifentanil doses than normotensive patients to maintain haemodynamic stability.
Why the study?
Does BIS-guided remifentanil-desflurane anaesthesia provide intraoperative haemodynamic stability in hypertensive compared to normotensive patients undergoing off-pump coronary surgery?

Does BIS-guided remifentanil-desflurane anaesthesia provide intraoperative haemodynamic stability in hypertensive compared to normotensive patients undergoing off-pump coronary surgery?
BIS-guided remifentanil-desflurane anaesthesia safely provides haemodynamic stability during off-pump coronary surgery, though hypertensive patients require higher remifentanil doses.

Hypertensives may require higher remifentanil doses for stability in off-pump surgery; leaves open optimal BIS-guided protocols.
OBJECTIVE: In this study, our aim was to investigate the efficacy and sufficiency of bispectral indeks (BIS) guided remifentanil-desflurane anaesthesia on intraoperative haemodynamic stability in both normotensive and hypertensive patients undergoing off-pump coronary artery bypass surgery. METHODS: Thirty adult, ASA I-III patients undergoing elective off-pump coronary surgery were included in the study. According to the presence of essential hypertension preoperatively, patients were divided into two groups. Haemodynamic parameters were recorded at 11 time points during the operation. RESULTS: There were no differences in the demographic data, heart rate and intraoperative and postoperative parameters between the groups. Arterial blood pressure and additional requirement of remifentanil were found to be significantly higher in the hypertensive group intraoperatively. CONCLUSION: In patients undergoing off-pump coronary revascularisation surgery, intraoperative haemodynamic stabilisation with remifentanil-desflurane anaesthesia under BIS guidance was safely provided, but higher remifentanil doses were required in hypertensive patients.

Ozturk et al. (2018) conducted a cohort in Elective off-pump coronary surgery (n=30). Essential hypertension vs. Normotensive patients was evaluated on Intraoperative haemodynamic stability and additional remifentanil requirement. Hypertensive patients undergoing off-pump coronary surgery required significantly higher intraoperative remifentanil doses than normotensive patients to maintain haemodynamic stability.
