INTRODUCTION
Ropivacaine is an aminoamide local anaesthetic that is less cardiac and central nervous system (CNS) toxic than other long acting local anaesthetics like bupivacaine. Local anaesthetics alone for supraclavicular brachial plexus block provide good operative conditions but have shorter duration of postoperative analgesia.
MATERIAL AND METHODS
This prospective study was conducted in the Department of Anaesthesia at KD Medical College, Hospital and Research from November 2021to April 2022.After obtaining permission from institutional ethics committee, written informed consent was taken from the participants. Eighty adult patients were randomly allocated to two equal groups (n = 40 in each group) using computer-generated random number list.Patients with the American Society of Anaesthesiologists (ASA) physical status I and II, aged between 25 and 55 years of both sexes undergoing elective orthopaedic surgeries of elbow, forearm, and hand under supraclavicular brachial plexus block were enrolled in the study.  The onset and duration of sensory and motor block, the perioperative vitals and requirement of post operative rescue analgesic were compared by us.
 
RESULTS
In group A 50% of patients achieved grade IV quality of block in comparison to 45% in group B which was not significant (p>0.05). 31 patients required rescue analgesic (intramuscular diclofenac sodium injection) in group A compared to 27 patients in group B.
Conclusion
We conclude that addition of 150 mg magnesium sulphate to ropivacaine 0.50% solution in supraclavicular brachial plexus block prolongs the duration of sensory and motor blockade and reduces the requirement of rescue analgesic in postoperative period with no significant adverse effects.

Background: Direct laryngoscopy followed by endotracheal intubation is prone to
haemodynamic fluctuations which may be detrimental in subjects with coronary artery
disease, hypertension, and cerebral vascular disease. The aim is we wanted to compare
Dexmedetomidine with Magnesium sulphate to determine the better drug with regard
to attenuation of the haemodynamic responses during laryngoscopy and endotracheal
intubation.

Background:Haemodynamic changes occurring during direct laryngoscopy and endotracheal
intubation are well tolerated by healthy individuals but can be fatal in patients with
hypertension, heart disease and intracranial hypertension. Many methods have been tried to
obtund these responses.
Methods: 60 consenting patients were randomised to receive 30 mg/kg of magnesium
sulphate (MgSO4) in 100 ml saline over 10 min before induction or preservative free 2%
lignocaine 1.5 mg/kg diluted to 5 ml with saline 90 secs before intubation. Heart rate,
systolic, diastolic & mean blood pressures and time taken to extubate were monitored.
Results: Hemodynamic parameters showed no significant rise at intubation in both the
groups. Time taken to extubate was similar in both the groups.
Conclusion: MgSO4 30 mg/kg given intravenously as infusionover 10 minutes prior to
induction and lignocaine 1.5 mg/kg given 90 seconds before intubation were comparable in
attenuating pressor response to laryngoscopy and intubation with no clinically significant
prolongation in time taken to extubate in MgSO4 group.
