Randomized Controlled TrialKetamine versus magnesium sulphate as an adjuvant to local anesthetics in the peribulbar block for posterior segment surgeries: a randomized controlled study.
The use of an adjuvant to local anesthetics in the peribulbar block may improve block characteristics. The aim of this double-blinded, parallel-group, randomized, controlled trial was to evaluate the safety and efficacy of ketamine versus magnesium sulphate as adjuvants to the local anesthetic mixture of peribulbar block in patients scheduled for vitreoretinal surgeries. ⋯ In vitreoretinal surgeries the use of either ketamine or magnesium sulphate as adjuvants to the local anesthetic mixture of peribulbar block improved the onset, duration, and quality of the block, offered better patient and surgeon satisfaction, and was not associated with drug adverse effects or surgical complications.

Is the Placement, Maintenance, and Removal of Femoral and Sciatic Catheters Associated With Bleeding Complications in Vascular Patients on Antithrombotics? A Single-Center, Retrospective Cohort Study.
Information on the safety of placement, maintenance, and removal of peripheral nerve blocks in the presence of therapeutic or prophylactic antithrombotics is limited to case reports. ⋯ This report investigates bleeding complications of femoral and sciatic perineural catheters in patients undergoing LLA on antithrombotics. We found that, except for 1 patient, most patients on varying combinations of antithrombotics did not experience bleeding complications related to the femoral and sciatic perineural catheters.

Cervical facet joint pain is often managed with either cervical radiofrequency neurotomy, cervical medial branch blocks, or cervical intraarticular injections. However, the effectiveness of each modality continues to be debated. Further, there is no agreement in reference to superiority or inferiority of facet joint nerve blocks compared to radiofrequency neurotomy, even though cervical facet joint radiofrequency neurotomy has been preferred by many and in fact, has been mandated by the Centers for Medicare and Medicaid Services (CMS), except when radiofrequency cannot be confirmed. Each procedure has advantages and disadvantages in reference to clinical utility, outcomes, cost utility, and side effect profile. However, comparative analysis has not been performed thus far in the literature in a clinical setting. ⋯ In this study, outcomes of cervical therapeutic medial branch blocks compared to radiofrequency neurotomy demonstrated significantly better outcomes with significant pain relief with similar costs for both treatments over a period of one year.
