Adverse heart rate responses during beach-chair position for shoulder surgeries - A systematic review and meta-analysis of their incidence, interpretations and associations.

Background And Aims: Evaluations of adverse heart rate (HR)-responses and HR-variations during anaesthesia in beach-chair-position (BCP) for shoulder surgeries have not been done earlier. We analysed the incidence, associations, and interpretations of adverse HR-responses in this clinical setting.

Methods: We performed a meta-analysis of trials that reported HR-related data in anaesthetised subjects undergoing elective shoulder surgeries in BCP.

Comparative Study between Propofol and Dexmedetomidine for Conscious Sedation in Patients Undergoing Outpatient Colonoscopy.

Introduction: Colonoscopy is a mildly painful procedure requiring conscious sedation. Though propofol is a widely used anesthetic agent in day-care procedures due to its rapid onset and quick recovery has a drawback of requiring resuscitation maneuvers more often than the conventional methods. Dexmedetomidine, a newly introduced, highly selective α-adrenergic receptor agonist possessing hypnotic, sedative, anxiolytic, sympatholytic, and analgesic properties with impressive safety margin, needs to be explored for use in conscious sedation for colonoscopy procedure among South Indian population.

Motor response evaluation during brachial plexus block anesthesia: An ultrasonography aided study.

Background: The sparing of ulnar nerve often leads to the failure of the upper limb blockade. It has been claimed that local anesthetic injection at the site of stimulator evoked finger flexion response is associated with highest success rate of a successful block. The lower trunk stimulation of plexus should yield similar results as this trunk contributes significantly for median and ulnar nerves of hand and forearm.
