Summary

The objective of this study is to compare two different doses of local anesthetics (10ml vs 20ml of 0.25% levobupivacaine) for subpectoral plexus block (SPPB) in addition to ultrasound guided multi-level of thoracic paravertebral block (m-TPVB) for surgical anaesthesia for major primary breast cancer surgery.

Conditions

Interventions

PROCEDURE

Subpectoral plexus block (low dose)

It is one type of peripheral nerve blocks for surgery over the chest. Patients will have an ultrasound scan and nerve block with local anesthetic (LA) agent (0.25% levobupivacaine 10ml) injected 2 target sites through one skin puncture. One at the myofascial plane between the pectoralis major and minor (5ml of LA) and then under direct ultrasound visualization, the needle will be redirected and the remaining 5ml of LA will be injected at the plane between the pectoralis minor and the serratus anterior muscle, close to the origin of thoracoacromial artery from the axillary artery at the level of the third rib.
