Local Ketamine Instillation for Postoperative Analgesia

Brief Summary

This study aims at exploring the analgesic efficacy, and safety of Ketamine instillation into the wound of total thyroidectomy compared to placebo,and to systemic ketamine administration (I.M. injection of the same dose) with respect to postoperative VAS, first request of analgesia, total opioid consumption, and with respect to possible side effects.

Intervention / Treatment

  • intra-wound instillation of ketamine (DRUG)
    intra-wound instillation of ketamine (1 mg/ kg) and normal saline in a total volume of 10 ml dispersed evenly throughout the wound; given after hemostasis and before wound closure
  • intra-wound instillation of normal saline (DRUG)
    intra-wound instillation of normal saline in a total volume of 10 ml dispersed evenly throughout the wound; given after hemostasis and before wound closure
  • systemic administration of ketamine (DRUG)
    intra-muscular administration of ketamine (1 mg/ kg), given before wound closure.
