Acute opioid tolerance: intraoperative remifentanil increases postoperative pain and morphine requirement.

abstract：BACKGROUND:QX-314 produces nociceptive blockade, facilitated by permeation through transient receptor potential vanilloid-1 (TRPV1) channels. TRPV1 channel can be activated by noxious heat and sensitized by volatile anesthetics. The authors hypothesized that emulsified isoflurane (EI) could enhance thermal TRPV1 channe...
