Background Acute lymphoblastic leukemia (ALL) has been previously shown to cause severe impairment in immunity, in turn making children more susceptible to viral infections, especially herpes zoster, which manifests with severe pain. Materials and methods The main purpose of this study was to experimentally evaluate the safety of nalbuphine on the neural tissues of rats treated with nalbuphine at doses of 0.5, 1, 2, 4, and 5 mg/kg injected intrathecally every alternate day for 14 days, and to determine the efficacy of caudal injection of nalbuphine with a minimal dose of oral paracetamol as an analgesic in pediatric patients with ALL suffering from acute herpetic pain. Results The results revealed that nalbuphine exerted no pathological changes in either the cerebellum or the spinal cord. However, the protective effect of nalbuphine with the minimal dose of paracetamol was associated with a significant analgesic effect in ALL children. Its analgesic effect was assessed by means of the Facial Pain Scale and the behavioral pain assessment scale, and motor block assessment was made on the basis of the Bromage score. Conclusion Caudal nalbuphine with a minimal dose of paracetamol has adequate analgesic effect on acute herpetic pain in pediatric patients with ALL, without any pathological changes in the cerebellum and spinal cord.
