Randomized Controlled Trial Comparative StudyRandomized prospective trial of cooled versus traditional radiofrequency ablation of the medial branch nerves for the treatment of lumbar facet joint pain.
No previous study has assessed the outcomes of cooled radiofrequency ablation (C-RFA) of the medial branch nerves (MBN) for the treatment of lumbar facet joint pain nor compared its effectiveness with traditional RFA (T-RFA). This study evaluated 6-month outcomes for pain, function, psychometrics, and medication usage in patients who underwent MBN C-RFA versus T-RFA for lumbar Z-joint pain. ⋯ When using a single diagnostic block paradigm with a threshold of >75% pain reduction, both treatment with both C-RFA and T-RFA resulted in a success rate of approximately 50% when defined by both improvement in pain and physical function at 6-month follow-up. While the success rate was higher in the C-RFA group, this difference was not statistically significant.

Randomized Controlled TrialClinical effectiveness of single dose of intravenous dexamethasone on the duration of ropivacaine axillary brachial plexus block: the randomized placebo-controlled ADEXA trial.
The effect of intravenous dexamethasone on the duration of axillary plexus block performed using ropivacaine is not described. The aim of this study is to assess the effect of intravenous dexamethasone on the duration of axillary plexus block analgesia after distal upper arm surgery. ⋯ This study showed that intravenous dexamethasone delayed for 6 hours the time to first analgesic intake after upper arm surgery under axillary plexus block performed with the long-lasting local anesthetic ropivacaine. This suggests that intravenous dexamethasone could be an interesting adjuvant to axillary plexus block.

Randomized Controlled Trial Comparative StudyComparison of dexmedetomidine and benzodiazepine for intraoperative sedation in elderly patients: a randomized clinical trial.
Elderly individuals have a greater sensitivity to sedation, and the most commonly used drugs for sedation are benzodiazepines, which exhibit some complication. Therefore, this study aimed to compare the use of dexmedetomidine and midazolam regarding proper sedation and postoperative complications in elderly individuals who require intraoperative sedation. ⋯ The use of DEX for sedation during surgery provides better control over the depth of sedation and produces fewer complications in elderly individuals.
