Description of intervention(s) / exposure
Thirty minutes prior induction of general anesthesia, Axillary Infiltration group: Patient in the supine position with the arm abducted. An anesthesiologist skilled with ultrasound guided regional anesthesia placed the ultrasound probe at the midclavicular level inferolaterally to locate the axillary artery and vein, and then moved laterally until the lower border of the pectoralis minor is identified at the level of the third or fourth rib. Needle advanced in the plane mode until the tip entered the area below the pectoralis half distance between the axillary vein and the rib and 20.5 ml of ropivacaine 0.5% was injected. The anesthesiologist is able to be sure that the quantity injected under ultrasound is in the fatty area of the axilla.

Comparator / control treatment
Thirty minutes prior induction of general anesthesia the Pec's group (Control Group): Patient in the supine position with the arm abducted. The anesthesiologist placed the ultrasound probe at the midclavicular level inferolaterally to locate the axillary artery and vein, and then moved laterally until pectoralis minor and serratus anterior muscles were identified at level of the third rib. Needle advanced in the plane of probe from medial to lateral in an oblique manner until the tip entered the plane between pectoralis major and minor and ropivacaine 0.5%, 10 ml was injected. After depositing the local anesthetic, the needle was advanced further until it lay in the potential space in the fascia between pectoralis minor and serratus anterior muscles, and ropivacaine 0.5%, 15 ml was deposited in this space.

Outcomes
Primary outcome [1]
320344
0
The duration of analgesia (time to first rescue analgesia after administration of block).
The time of performance of the block was noted by the anesthesiologist, the time of first dose of narcotics administered to the patient in the post operative period was noted by the nurse incharge on the floor. The duration of analgesia (time to first rescue analgesia after administration of block) can be calculated subsequently.

Summary
Brief summary
In our study we introduced a new technique for postoperative control of pain in patients undergoing breast surgery. The technique consisted of infiltrating the axillary fat area with ropivacaine by using ultrasound. Hypothesis: the new technique is effective as Pec's II block on postoperative analgesia.
