Filter by:Epidural anesthesia is a very useful tool in lower limb salvage surgery, which helps pain control intra and more importantly post-operative pain. It is a well-known effect of epidural injections to cause a sympathetic stimulation and consequently vasodilatation in the lower limb vessels. Since epidural catheters can cause vasodilatation in lower limb vessels, they can subsequently lead to increased intra and post-operative bleeding from the surgical wound. The study will involve all patients having a bone tumor in the lower limb and subjected to tumor resection and reconstruction by prosthesis. The patient will be randomized according to the administration of epidural anesthesia into two arms, an arm in which epidural anesthesia was employed and another arm in which the patient was subjected only to general anesthesia and the amount of intra and postoperative bleeding will be compared in both arms.
The purpose of this study is to see whether fast imaging with MRI and the usual contrast material used for MRI, predicts which patients will do well with treatment. Some studies suggest that MRIs done right before surgery may be able to tell how much of the cancer was killed by the chemotherapy. This study will see if this is true in patients with osteogenic sarcoma (OS) and Ewing's sarcoma (ES). This study will also see if MRIs done early in treatment can tell if the chemotherapy is working.
