Comparing Postoperative Analgesia:Interscalene block versus Suprascapular with Infraclavicular block for Arthroscopic shoulder cuff repair.

We will be recruiting 60 ASA grade 1 to 3 patients age group 18 to 75 years in each group .Patients  with shoulder cuff injuries for arthroscopic cuff repairs and willing to participate will be included.Patients with severe cardiac,pulmonary,renal,hepatic diseases ,allergic to local anaesthesic drugs ,pregnant patients,and coagulopathies and emergency patients will be excluded.Patients refusing to participate or not able to give consent will be excluded.

All patients will receive standardised general anaesthesia followed by the block as per randomisation.

Group 1 will receive ultrasound guided interscalene block 12 ml of 0.2 %Ropivacaine with 30 micrograms of clonidine.

Group 2 will receive ultrasound guided Suprascapular block 5 ml and infraclavicular block 10 ml of 0.2%Ropivacaine with 30 micrograms of clonidine .

Patients will be monitored postoperative VAS NRS score,PONV at regular intervals,

IV Paracetamol will be used for breakthrough pain if NRS is more than 4 .A 24 hour Fentanyl consumption will be compared in both groups which will be primary outcome.Secondary outcomes will be comparison of VAS scores ,hemodynamics and PONV.

Complications related to block performance (LAST),blood on aspiration will be noted and compared.

With the help of biostatistician the collected data will be analysed.

Consent procedure:consent will be taken in the language best understood by the patient and will include the description of the purpose of the study ,the protocol involved,risks and benefits and the choice of exiting the study at any point of time.
