Hypericum perforatum to Improve Postoperative Pain Outcome After Monosegmental Spinal Sequestrectomy (HYPOS): Results...

Patients undergoing lumbar spine surgery often suffer from severe radicular postoperative pain leading to the prescription of high-dose opioids. In Integrative Medicine, Hypericum perforatum is known as a remedy to relieve pain caused by nerve damage. This trial investigated whether homeopathic Hypericum leads to a reduction in postoperative pain and a decrease in pain medication compared with placebo. Randomized double blind, monocentric, placebo controlled clinical trial. Department of Neurosurgery, Community Hospital Herdecke. Inpatients undergoing lumbar sequestrectomy surgery. Homeopathic treatment versus placebo in addition to usual pain management. Primary endpoint was pain relief measured with a visual analog scale. Secondary endpoints were the reduction of inpatient postoperative analgesic medication and change in sensory and affective pain perception. Baseline characteristics were comparable between the groups. Pain perception between baseline and day 3 did not significantly differ between the study arms. With respect to pain medication, total morphine equivalent doses did not differ significantly. However, a statistical trend and a moderate effect (d = 0.432) in the decrease of pain medication consumption in favor of the Hypericum group was observed. This is the first trial of homeopathy that evaluated the efficacy of Hypericum C200 after lumbar monosegmental spinal sequestrectomy. Although no significant differences between the groups could be shown, we found that patients who took potentiated Hypericum in addition to usual pain management showed lower consumption of analgesics. Further investigations, especially with regard to pain medication, should follow to better classify the described analgesic reduction. German Clinical Trials Register No: DRKS00007913.
