Task: Answer Verification
Input (English): Question: Is ultrashort acting remifentanil superior to long-acting sufentanil in preserving cognitive function-a randomized study?
Answer: We could not demonstrate differences in POCD between remifentanil and sufentanil based anaesthesia, but in general, the fraction of patients with POCD seemed smaller than previously reported. We found an association between POCD and both perioperative low Svo2 and postoperative ventilation time, underlining the importance of perioperative stable hemodynamics and possible fast-track protocols with short ventilation times to attenuate POCD.
Output (English): no
