A Randomized Clinical Trial

After the induction of general anesthesia, PECS block was administered patients via ultrasound guided technique. We used Mindray M7 Portable ultrasound system using linear probe with (5-10 MHz) frequency. After cleaning the infra clavicular and axillary region with 2% chlorhexidine in 70% Alcohol solution, ultrasound probe was placed in the infraclavicular region and pectoral major and minor were identified. After identification of the landmarks, 20 gauge 50mm Visoplex needle was inserted in-plane direction. 20ml of 0.25% bupivacaine (within the safe limit of its dose) was infiltrated between pectoralis major and pectoralis minor muscle and the spread was visualized on the ultrasound screen.
