Abstract Background In most scenarios, anaesthesiologists titrate opioids to control nociceptive surgical stress based on intraoperative haemodynamic changes. Remifentanil was reported to cause more profound cardiovascular depression than sufentanil. A concern is that this direct cardiovascular depression might counteract the hypertension and tachycardia caused by surgical manipulation and mask inadequate analgesia. Objective To compare remifentanil and sufentanil, titrated to maintain a comparable haemodynamic range (within 20% of baseline) and combined with the same propofol regimen, in stress reduction measured as plasma levels of putative mediators of surgical stress. Setting Huashan Hospital of Fudan University, Shanghai, China. Method Forty-five patients undergoing supratentorial glioma resection were randomised to the remifentanil group or the sufentanil group. Main outcome measures Plasma concentrations of cortisol, epinephrine, norepinephrine, interleukin-6, interleukin-10 and lymphocyte counts were analysed before anaesthesia, 1 h after incision, at the end of surgery and 24 h after incision using enzyme-linked immunosorbent assay and an automatic haematology analyser. Recovery profiles during emergence from anaesthesia were also compared. Results Except for a lower epinephrine concentration in the remifentanil group 24 h after incision (median [interquartile range], 4.2 [3.4–6.1] vs. 8.4 [4.8–12.5] ng/ml; P = 0.003), stress biomarkers were not significantly different between the two groups. Patients in the sufentanil group had lower grades in coughing, restlessness (P = 0.001 and 8 ml/kg, respiratory rate > 8 times/min, end-tidal C O2
