Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
At the end of breast surgery operation anesthesiologists will perform pectoral nerve blocks patients in intervention group. After skin disinfection first anesthesiologists will give 20 ml %0.25 bupivacaine to fascia which lies between pectoralis minor and serratus anterior muscles between 3. and 4. ribs guided under ultrasound view. Then the same amount of bupivacaine will be given fascia which lies between pectoralis major and minor muscles. We will use appropriate needles for this intervention.It will take approximately 5 minutes.

Summary
Brief summary
Using opioids for postoperative analgesia is a standard modality. But opioid related side effects like nausea-vomiting, respiratory depression, urinary retention, Pruritus limits its use. Peripheral nerve and truncus block with local anesthetics can improve postoperative analgesia and reduce opioid requirement.
Our primary purpose in this study ; to investigate effect of pectoral nerve blocks on postoperative analgesia and total opioid consumption in aesthetic breast surgery
operation..
We will take written informed consent for all patients before the procedure. We will record age, height, weight, American Society of Anesthesiologists (ASA) physical status of all patients.We will randomize patients into two group with computer program.In the operation room, we will routinely monitor electrocardiography, peripheric oxygen saturation and blood pressure.Standard anesthesia induction will perform for general anesthesia.
At the end of breast surgery operation we will perform pectoral nerve blocks patients in intervention group. After skin disinfection first we will give 20 cc %0.25 bupivacaine fascia which lies between pectoralis minor and serratus anterior muscles between 3. and 4. ribs guided under ultrasound view. Then the same amount of bupivacaine will be given fascia which lies between pectoralis major and minor muscles. We will use appropriate needles for this intervention.It will take approximately 5 minutes. Both group ( control and intervebntion group) will take same postoperative analgesics routinely.
Postoperative analgesia will provided with patient controlled analgesia (PCA) device which contains opioid drugs. Postoperative analgesia will measure with visual analog scale for pain and opioid consumption with PCA datas postoperative 0,1,2,4,6,8,12 and 24. hours .
