  Efficacy of intrathecal esmolol on heat-evoked responses in a postoperative pain model.

  Perioperative tachycardia and hypertension are often treated with esmolol, a short-acting β1-adrenoceptor antagonist. Besides its cardiac effect, esmolol is reported to exert antinociceptive effects. This study examined the efficacy of intrathecal (IT) esmolol on pain responses in a postoperative pain model. ⋯ No postoperative antinociceptive effects of esmolol were observed at 10 or 15 minutes. IT administration of esmolol produced antinociceptive effects of short duration in a rat postoperative pain model. These results suggest that IT esmolol could offer a new strategy for managing perioperative pain, although an alternative approach is necessary to lengthen the duration of the analgesia.
