Summary We retrospectively compared patients receiving remifentanil with patients receiving sufentanil undergoing fast‐track cardiac surgery. After 1:1 propensity score matching there were 609 patients in each group. The sufentanil group had a significantly longer mean (SD) ventilation time compared with the remifentanil group; 122 (59) vs. 80 (44) min, p < 0.001 and longer mean (SD) length of stay in the recovery area; 277 (77) vs. 263 (78) min, p = 0.002. The sufentanil group had a lower mean (SD) visual analogue pain score than the remifentanil group; 1.5 (1.2) vs. 2.4 (1.5), p < 0.001 and consumed less mean (SD) piritramide (an opioid analgesic used in our hospital); 2.6 (4.7) vs. 18.9 (7.3) mg, p < 0.001. The results of our study show that although remifentanil was more effective in reducing time to tracheal extubation and length of stay in the recovery area, there was an increased requirement for postoperative analgesia when remifentanil was used.

In a preselected patient population, fast-track treatment could be done with a low FTF rate. Independent risk factors for FTF are age, female sex, prolonged surgery, and prolonged cross-clamp time.

The purpose of this study was to compare patients who underwent on- vs. off-pump coronary artery bypass surgery managed with a fast-track protocol. Between September 2012 and December 2018, n = 3505 coronary artery bypass surgeries were managed with a fast-track protocol in our specialized post-anesthesia care unit. Propensity score matching was applied and resulted in two equal groups of n = 926. There was no significant difference in ventilation time (on-pump 75 (55–120) min vs. off-pump 80 (55–120) min, p = 0.973). We found no statistically significant difference in primary fast-track failure in on-pump (8.2% (76)) vs. off-pump (6% (56)) groups (p = 0.702). The secondary fast-track failure rate was comparable (on-pump 12.9% (110) vs. off-pump 12.3% (107), p = 0.702). There were no significant differences between groups in regard to the post-anesthesia care unit, the intermediate care unit, and the hospital length of stay. Postoperative outcome and complications were also comparable, except for a statistically significant difference in PACU postoperative blood loss in on-pump (234 mL) vs. off-pump (323 mL, p < 0.0001) and red blood cell transfusion (11%) and (5%, p < 0.001), respectively. Our results suggest that on- and off-pump coronary artery bypass surgery in fast-track settings are comparable in terms of ventilation time, fast-track failure rate, and postoperative complications rate.
