A Clinical Comparative Study of Dexmedetomidine, Dexamethasone, and Clonidine as Adjuvants to Local Anesthetics in Supraclavicular Brachial Plexus Blocks.

Anaesthesiology, Gajra Raja Medical College, Jaya Arogya Group of Hospitals, Gwalior, IND.
Introduction: The brachial plexus block is one of the peripheral blocks, beneath which the majority of upper limb surgical procedures are carried out. During upper limb surgery, a supraclavicular nerve block is an excellent substitute for general anesthesia.
Aim: This is a clinical comparative study of dexmedetomidine, dexamethasone, and clonidine as adjuvants to local anesthetics in supraclavicular brachial plexus block.

Neuroinflammation is a key factor in the pathogenesis of Parkinson's disease (PD). Activated microglia in the central nervous system (CNS) and infiltration of peripheral immune cells contribute to dopaminergic neuron loss. However, the role of peripheral immune responses, particularly triggering receptor expressed on myeloid cells-1 (TREM-1), in PD remains unclear.

Anesthesiology and Critical Care, Uttar Pradesh University of Medical Sciences, Etawah, IND.
Background: In epidural anaesthesia, the addition of an adjuvant to local anaesthetics enhances the efficacy, thereby providing increased duration and intensity of blockade in lower limb surgeries. The aim was to compare the efficacy, onset, and duration of sensory and motor blockade; haemodynamic changes; and sedative and analgesic effects of nalbuphine, clonidine, and dexmedetomidine as an adjuvant to ropivacaine in epidural anaesthesia.
Methodology: A prospective, randomised, double-blind study among 90 patients after taking consent was divided into three groups (30 patients each; Group D received 15 ml of 0.
Effects of different approaches of infraclavicular brachial plexus block on perfusion index and tissue perfusion.

Department of Anesthesiology and Reanimation, Zonguldak Bülent Ecevit University Medicine Faculty, Zonguldak, Türkiye.
Background: Although both the lateral sagittal and costoclavicular approaches are applied at the cord level in the infraclavicular region, there is a major difference between the distributions of the two approaches. We aimed to investigate the effects of this different distribution on tissue perfusion and oxygenation.
Methods: Sixty patients undergoing elective elbow, forearm, wrist and hand surgery under infraclavicular brachial plexus block were included in the study.
Efficacy of long-acting local anesthetics versus their mixture with shorter-acting local anesthetics for peripheral nerve blocks guided by ultrasound: a systematic review with meta-analysis of randomized controlled trials.

State University of Campinas, Campinas, SP, Brazil.
Background/importance: Local anesthetic (LA) mixtures are used in peripheral nerve blocks (PNB) to improve onset, though study results remain conflicting.
Objective: This systematic review and meta-analysis compared the efficacy outcomes of long-acting LA to their mixture with shorter-acting LA in ultrasound-guided PNB. The primary outcome was sensory block onset.
