Active clinical trials for "Intervertebral Disc Displacement"

This study focused on to determine postoperative analgesic efficacy of tramadol compared to tramadol with addition of paracetamol after a lumbar disc surgery.

Pregabalin is claimed to have superior analgesic effect at lower doses and better pharmacological profile as compared to gabapentin esp. in perioperative pain control after major surgeries like intervertebral disc surgery. The investigators found that pregabalin is equivalent to gabapentin for relief of post-operative pain at a lower dose in patients undergoing intervertebral disc surgery.

Guidelines advocate several complementary modalities as alternatives to drugs and other invasive treatments for chronic low back pain (LBP) conditions. However, there is little high-quality research investigating treatments for back-related leg pain, one of the more severe and disabling presentations of LBP. The investigators are conducting a pilot study to assess the feasibility of a future phase II multi-site randomized clinical trial (RCT). The future trial will assess the comparative effectiveness of a novel supported biopsychosocial self-management (SBSM) intervention versus Medical Care (MC).

The purpose of this study is to Compare three methods of intrathecal bupivacaine; bupivacaine-fentanyl; bupivacaine-fentanyl-magnesium sulfate on sensory-motor blocks and postoperative pain in patients undergoing lumbar disk herniation surgery.

The primary objective of this study is to compare the early clinical outcomes following non-surgical treatment with Triojection® to surgical discectomy. Early is defined as less than or equal to 6 months.

This is an investigator-initiated study. The primary goal is to evaluate the efficacy of two different cervical disc devices (prosthesis vs rigid spacer) with respect to postoperative change in neck disability index. The evaluation will include clinical and radiological parameters.

Transforaminal lumbar interbody fusion (TLIF) had been favorable for effectively decrease pain and disability in specific spinal disorders; however, there has been concern regarding pedicle screw placement during TLIF surgery. Recently, several biomechanical studies had demonstrated that CBT technique achieves screw purchase and strength equivalent to or greater than the traditional method. Furthermore, Only 1 report examined the surgical outcomes of TLIF with CBT screws fixation compared with TLIF using traditional pedicle screws fixation. TLIF with CBT screws fixation may be effective for specific spinal disorders, but the evidence supporting this possibility is still limited.

The purpose of this study is to evaluate the feasibility and efficacy of US-MR image fusion-guided percutaneous transforaminal endoscopic discectomy for the treatment of lumbar disc herniation

Evaluation of outcome of DCI in treatment of cervical disc disease to patients admitted to neurosurgery department, Asyut University Hospitals. Give the effective treatment, pain control and can detect the best method could be used. Improve the outcome of these patients and decease rate of recurrence and complications.

High blood pressure is a serious and common health problem. This disease affects 1 billion people all over the world and responsible for 7,1 million deaths. Trials involving more than 1 million people state that stroke incidence rises as blood pressure rises. The effects of high blood pressure on cerebral perfusion is not well realized. Intraoperative blood pressure management of patients with high blood pressure is not well known. And it is still not clear how autoregulation of cerebral perfusion is affected by high blood pressure. Systemic arterial pressure changes have little effect on cerebral perfusion. This is regulated by changes of precapillary resistance. When systemic arterial blood pressure drops, it is regulated by vasodilatation of arteriolar smooth muscles. And when systemic blood pressure rises, it is regulated by vasoconstriction of arterioles. Cerebral perfusion is well preserved between 50-125 mmHg changes of mean arterial blood pressure (MAP). Patients with high blood pressure have higher ranges. Patients with chronic high blood pressure can better tolerate higher blood pressures. But even physiologic drops of systemic blood pressure can cause ischemia. Anesthetic drugs have variable effects on cerebral blood flow and physiology. The drugs used with anesthetic drugs, the noxious stimulus of surgery, intracranial compliance, blood pressure, and carbon dioxide pressure can all alter and complicate these effects. Anesthetic drugs must be selected carefully in patients with high blood pressure. It is still investigated whether, management of blood pressure under anesthesia, should be individualized. For patients with high blood pressure, some neuromonitorization technics have been evaluated to prevent neurologic complications under anesthesia. But there is not a technic, which is considered as a gold standard. Cerebral blood pressure has been studied by, nitrous oxide method, krypton uptake method, and xenon injection methods previously. Near-infrared spectroscopy (NIRS) is the best monitorization technic of intracranial pressure (ICP), cerebral blood flow (CBF), and cerebral metabolism. But it can not be applied to all patients. Recently, it is possible to measure blood flow of cerebrum with transcranial Doppler ultrasound in anesthesia practice. In this trial, the investigators aim to evaluate cerebral perfusion of hypertensive patients with transcranial Doppler during lumbar disc surgery to optimize the blood pressure under anesthesia. To best of our knowledge, there is no trial evaluating cerebral perfusion of hypertensive patients with transcranial Doppler ultrasound.
