STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person allocating the participants to the intervention arms Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Simple randomization using a randomization table created by a computer software program Numbered containers Masking/blinding used Participants
INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Control Group group C received 25ml of 0.2 ml/kg of 0.25% of plain bupivacaine were used for modified PEC’s block. One hour before surgery Modified PEC's two-block was performed under ultrasound guidance using SonoSite M Turbo (SonoSite, USA) with linear multifrequency 6–13 MHz transducer (L25 × 13–6 MHz linear array) scanning probe. Under complete aseptic condition and with the patient in the supine position with the arm abducted 90o. The probe was applied at the med clavicular level and angled inferolateral. The pectoralis muscle was identified with the axillary artery and vein on sonography. The brachial plexus should be visible underneath. 10 ml of the test solution was injected between the pectoralis major and minor. Then the probe was turned laterally to identify the pectoralis minor and serratus anterior muscles then 15 ml of test solution was injected. 54 Active-Treatment of Control Group
