Clinical Experience with Repeated Ketamine Administration for Procedures Requiring Anesthesia
We have given Ketamine repeatedly to eight patients, ages 15 years and less. The frequency of administration of the anesthetic has varied from a daily basis to a schedule of 2 or 3 injections per week. The period of treatment has ranged from 13 to 40 days. Seven of the patients, ranging in age from 2 months to 4 years, were being treated for primary or metastatic neoplastic disease of the eyes. Four of them had retinoblastomas; two had metastatic neuroblastomas, and one a sarcoma. They were anesthetized to facilitate keeping them in proper position for radiation therapy of the eye. No further manipulation was needed.
