Randomized Controlled Trial Multicenter Study Comparative StudyIntra-articular Adjuvant Analgesics following Knee Arthroscopy: Comparison between Single and Double Dose Dexmedetomidine and Ropivacaine A Multicenter Prospective Double-blind Trial.
Knee arthroscopy is a commonly performed orthopedic procedure. Post-operatively, adequate pain relief reduces the surgical stress response and patient's morbidity and facilitates rehabilitation. The analgesic effect of dexmedetomidine (2 μg/kg body weight) as an adjunct to ropivacaine in knee arthroscopic knee procedures was studied to determine whether this would achieve longer post-operative analgesia and whether the study dosage of dexmedetomidine was safe and free of adverse effects. ⋯ Intra-articular dexmedetomidine (2 μg/kg) has superior analgesic efficacy, delayed the first postoperative requirement for analgesia and decreasing the need for postoperative analgesics with no major adverse effects.

Unilateral hemilaminectomy (UHIL), an alternative surgical approach to intradural lesions, involves a unilateral approach to meningeal opening that provides an adequate window for tumor extraction while leaving most of the vertebral structures intact. The techniques and results of a modified hemilaminectomy technique with spinal endoscopy is discussed and limited unilateral hemilaminectomy for intradural tumors (UHIT) evaluated prospectively. ⋯ Our data suggest that there is a place for the UHIT approach. This minimally invasive approach is useful for resecting all intradural tumors. UHIL is a useful minimally invasive technique for resecting intradural spinal tumors with maximal preservation of musculoligamentous attachments and posterior bony elements and should be considered an improvement on currently employed techniques.
