Official title
Effects of Intrathecal Morphine on Transcranial Electric Motor-Evoked Potentials in Patients Undergoing Posterior Spine Fusion
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Patients undergoing posterior spinal fusion (PSF) procedures for scoliosis are at risk for iatrogenic neurologic injury of the spinal cord and/or spinal nerve roots during surgical correction of the abnormal spinal curvature. The degree of neurologic injury can range from minor sensory deficits to complete paraplegia. Surgeons at CHOP utilize neurophysiologists to identify impending neurologic injury. These consultants monitor spinal cord pathways by recording and analyzing evoked potentials during the operation. Evoked potentials are low voltage electrical signals generated in response to transcranial or transcutaneous electrical stimulation of motor and sensory neural pathways. Some patients undergoing PSF receive an injection of morphine into the cerebrospinal fluid during the operation. This intrathecal (IT) morphine has potent analgesic effects. While most commonly used anesthetic agents have well-characterized effects on evoked potentials, little data exists on the effects of IT morphine on transcranial electric motor-evoked potentials (TceMEPs). This is a prospective observational study to characterize the effects of IT morphine on TceMEPs.
