16Comparative Treatments

i Description/ name of comparative treatments

There will be two kinds of fluid injected for pectoral nerve, A & B, A = saline (group of without pectoral nerve block), B = local anesthetic (group of with pectoral nerve block). There is 50:50 chance of getting either drug which is determined by the allocation. No matter which drug is used, it will not affect your surgery because rescue analgesia will be administered whenever necessary during the surgery. The group of local anesthetic injection is expected to provide better analgesia in combination with multi-level thoracic paravertebral nerve block for breast cancer surgery.

22 Recruitment Status

Unknown

23 Primary Outcome

The midazolam, dexmedetomidine, ketamine, and other rescue analgesic used during the surgery will be recorded.

24 Secondary Outcome

Pain at rest and on movement on the surgery site will be assessed in the recovery room. Before discharge from the recovery room, the motor power grade of the pectoral major and minor muscles supplied by pectoral nerve and 4 nerves of the brachial plexus as injection is close to the brachial plexus will be assessed. In the ward, the pain score, nausea score, supplementary paracetemol, morphine and ondestron used will be recorded at regular intervals in the ward for 48 hours.
