Retrobulbar Block Versus Ketamine Infusion for Post-enucleation Analgesia

Brief Summary

This study compares the efficacy and safety of two techniques, retrobulbar block versus intra-operative ketamine infusion, for control of post-operative pain occurring in patients undergoing ocular enucleation or evisceration performed under general anesthesia.

Intervention / Treatment

  • Retrobulbar block (PROCEDURE)
    Patients will receive a single retrobulbar injection with 3-4ml of an equal mixture of Lidocaine 2% \& Bupivacaine 0.5% + Hyaluronidase (10 IU/ml), after induction of general anesthesia.
  • Ketamine (PROCEDURE)
    Patients will receive a 0.5 mg/kg bolus followed by an infusion of 0.25 mg/kg/h of intravenous Ketamine, after induction of general anesthesia.
