Abstract

Objective: Comparison of adverse effects of anterior dental plane anesthesia analgesia under ultrasound guidance with levobupivacaine 0.25% plus 4 mg dexamethasone after breast cancer surgery. Methods: RCT study on 70 patients divided two groups. Group 1: Serratus anterior plane block under ultrasound guidance with 30ml levobupivacaine 0,25%. Group 2: Serratus anterior plane block under ultrasound guidance with mixture of 30ml levobupivacaine 0,25% and 4 mg dexamethasone. The patient was fitted with IV-PCA morphine, with a bolus dose of 1mg/time, a lock-in time between 2 bolus injections was 8 minutes, a maximum dose of 6 times/hour and was instructed to start when VAS score ≤ 3. Results: At the time of the study, there were no differences between the two groups in terms of respiratory, circulatory, side effects: itching, dizziness, urinary retention, stomach pain, gastrointestinal bleeding, nausea and vomiting.
