Establishing Technique for PECS2 Catheter Insertion (ETCI)

The investigators are trying to establish an easy technique for insertion of a catheter for continuous infusion while performing pectoral type 2 (serratus) block, as a post operative pain controlling measure for cases undergoing simple mastectomy, using ultrasound guidence

As the space between the pectoralis minor and the serratus anterior is a fashial plane with a connective tissue occupying. we are trying to demonstrate a simple technique for inserting a catheter within that fashial plane and making sure of the catheter position, to ensure post operative analgesia for cases performing simple mastectomy. Now the Pectoralis type 2 block (PECS type 2) is an established technique as regional block technique for chest wall procedures. We are trying to maximizing the benefit of the block with a catheter insertion to use it for continuous infusion of bupivacaine for controlling post operative pain in cases performing simple mastectomy procedure

B Braun Catheter Kit Contiplex with a 18 gauge needle will be used. After topicalization of the skin and sterilization using ultrasound guidance to facilitate performing insertion of the canula. Confirming the tip position will be done by ultrasonography while performing pectoralis type 2 block for cases undergoing simple mastectomy procedures
