Not yet recruiting

Conditions: Other intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified, (2) ICD-10 Condition: O||Medical and Surgical,

Registration Number: CTRI/2022/03/041352

Lead Sponsor: Sawai Mansingh Medical College and Hospital

Brief Summary: Patient satisfying inclusion criteria will be selected and taken in OT

Patient identity will be confirmed, PAC will be done and informed written consent will be checked.

Noninvasive monitors (NIBP,Pulse oximeter,ECG) will be monitored and ringer lactate will be started intravenously

Patient will lie in supine position, with the head turned to the opposite side. Under all aseptic precautions, ultrasound guided supraclavicular brachial plexus block will be performed after explaining the procedure in each group. Using sonosite micromaxx high frequency linear probe

Group A (n=102) USG guided singlepoint injection supraclavicularblock given by injecting 15ml of 0.5% Ropivacaine

Group B(n=102) USG guided multiple point injection supraclavicular block given by injecting 15ml 0.5% Ropivacaine

Here, time required to complete the procedure in each group will be recorded

Patients will be evaluated for onset of sensory and motor block every 2 minutes for first 10 minutes and later 5 minutes till half an hour after completion of injection of local anesthetic . Sensory blockade will be assessed by Pin Prick and Cold Test. Motor block will be assessed by asking the patient to move elbow, wrist and fingers.

Sparing of nerves will be noted and supplemented. The onset times of sensory and motor block will be noted.

Once the patient will achieve sensory block of grade 2 then surgeons

will be asked to proceed. Injection Midazolam 0.02mg/kg will be given to every patient for his/her comfort.

Hemodynamic parameters (Heart rate, NIBP and SPO2) will be monitored every 5 minutes for the first half an hour and thereafter every 15 minutes

administration of postoperative analgesic (Inj. Diclofenac 75 mg IV) and Inj. Tramadol 100 mg IV
