NCT04061668

Brief Summary

The patients are allocated by computer generated random number method into 2 groups: single needle path PECS I and II block group, where patients receive induction with pec I and II blocks which are performed under ultrasound guidance , with a linear ultrasound transducer on the same side of surgery. The patients are placed in the supine position where the elbow was flexed and shoulder will be abducted. The probe is placed inferior to the clavicle . A linear probe and a beveled tip needle will be introduced with an in-plane technique . The US probe is initially placed below outer third of the clavicle after skin sterilization showing pectoralis major and minor muscles and the thoraco- acromial artery then moved infero-laterally to locate fourth rib where pectoralis major and pectoralis minor muscles are visualised . The US probe is then moved toward anterior axillary line till pectoralis minor and serratus anterior muscles are identified at 4th rib at the level of thoraco-acromial artery then the needle is inserted in plane with the probe from caudal to cranial using an inclined manner, 15mL of bupivacaine will be put into the potential space between pectoralis minor muscle and serratus muscle (PECS II) then it will be withdrawn to inject another 15 ml of bupivacaine in the plane between pectoralis muscles . The block will be performed with needle introduced in-plane with the ultrasound probe, and the local anesthetic (LA) injection is visualized . In double needle path PECS I and II block group The probe is initially placed below outer third of the clavicle after skin sterilization showing pectoralis major and minor muscles and the thoraco- acromial artery then moved inferolaterally to locate fourth rib where pectoralis major and pectoralis minor muscles are visualised, then the needle is inserted in plane with the probe and 15mL of bupivacaine is put into the potential space between pectoralis muscles. In the second puncture , the probe is moved toward anterior axillary line till pectoralis minor and serratus anterior muscles will be identified at 4th rib at the level of thoraco-acromial artery then the needle will be inserted in plane with the probe from caudal to cranial , 15mL of bupivacaine is put into the potential space between pectoralis minor muscle and serratus muscle (PECS II).

OTHER

The probe is placed inferior to the clavicle . A probe and needle is introduced with in-plane technique . The US is placed below outer third of the clavicle showing pectoralis major and minor muscles then moved infero-laterally to locate fourth rib where pectoralis major and pectoralis minor muscles is visualised . The US probe is moved toward anterior axillary line till pectoralis minor and serratus anterior muscles will be identified at 4th rib at the level of thoraco-acromial artery then the needle is inserted from caudal to cranial using an inclined manner, 15mL of bupivacaine 0.25% is put between pectoralis minor muscle and serratus muscle (PECS II) then it is withdrawn to inject 15 ml of bupivacaine in thel plane between pectoralis muscles . The block will be performed with needle introduced in-plane with the ultrasound probe, and the local anesthetic injection will be visualized .

Other: single needle path PECS I and II block group

double needle path PECS I and II block group

SHAM COMPARATOR

The probe will be placed below outer third of the clavicle showing pectoralis major and minor muscles and the thoraco- acromial artery then moved inferolaterally to locate fourth rib where pectoralis major and pectoralis minor muscles are visualised, then the needle is inserted in plane with probe and 15mL of bupivacaine are put into between pectoralis muscles. In the second puncture , the US probe is moved toward anterior axillary line till pectoralis minor and serratus anterior muscles are identified , the needle will be inserted in plane with the probe from caudal to cranial , 15mL of bupivacaine will be put into the potential space between pectoralis minor muscle and serratus muscle (PECS II).

Other: double needle path PECS I and II block group

single needle path PECS I and II block group(

The US probe will be initially placed below outer third of the clavicle after skin sterilization showing pectoralis major and minor muscles and the thoraco- acromial artery then moved inferolaterally to locate fourth rib where pectoralis major and pectoralis minor muscles will be visualised, then the needle will be inserted in plane with the probe and 15mL of bupivacaine 0.25% after negative aspiration will be put into the potential space between pectoralis muscles. In the second puncture , the US probe will be moved toward anterior axillary line till pectoralis minor and serratus anterior muscles will be identified at 4th rib at the level of thoraco-acromial artery then the needle will be inserted in plane with the probe from caudal to cranial in an inclined way, 15mL of bupivacaine 0.25% after negative aspiration will be put into the potential space between pectoralis minor muscle and serratus muscle (PECS II).
