Effects of halothane and isoflurane on hyperexcitability of spinal dorsal horn neurons after incision in the rat.

abstract：BACKGROUND:There is an unmet clinical need to develop a pharmacological therapy to counter opioid-induced respiratory depression without interfering with analgesia or behavior. Several studies have demonstrated that 5-HT1A receptor agonists alleviate opioid-induced respiratory depression in rodent models. However, ther...
