Study Details

Study Description

Brief Summary

Postoperative pain is an important issue in female patients underwent breast surgery. Postoperative effective pain treatment provides early mobilization and shorter hospital stay. The US-guided erector spina plane block (ESPB) may be used for postoperative pain treatment following breast surgery. It is a relatively novel interfascial block that was defined by Forero et al. It has been reported that ESPB provides effective analgesia management for several breast surgeries.

Detailed Description

Various methods may be performed to reduce the use of systemic opioids and for effective pain treatment following mastectomy and axillary dissection surgery. Ultrasound (US)-guided interfascial plane blocks have been used increasingly due to the advantages of ultrasound in anesthesia practice.

The US-guided erector spina plane block (ESPB) provides thoracic analgesia at T5 level and abdominal analgesia at T7-9 level. ESPB contains a local anesthetic injection into the deep fascia of erector spinae. Visualization of sonoanatomy is easy, and the spread of local anesthesic agents can be easily seen under the erector spinae muscle. Thus, analgesia occurs in several dermatomes with cephalad-caudad way. In the literature, it has been reported that ESP block provides effective analgesia after several surgeries such as open heart surgery, breast surgery, thoracoscopic and abdominal operations.

The aim of this study is to compare the efficacy of the different volumes of US-guided ESPB for postoperative analgesia after mastectomy and axillary dissection surgery. The primary aim is to compare postoperative opioid consumption, and the secondary aim is to evaluate pain scores (VAS), and adverse effects related with opioids (allergic reaction, nausea, vomiting).

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Group 30 = 30 ml of Erector spinae plane block group

In group 30 ml, ESPB will be performed with patients in the lateral decubitus position while the surgical site up. US probe will be placed 2-3 cm lateral to the T4 transvers process. The block needle will be inserted cranio-caudal direction and then for correction of the needle 5 ml saline will be injected deep into the erector spina muscle fascia. Following confirmation of the correct position of the needle 30 ml %0.25 bupivacaine will be administered for block.

Drug: Bupivacaine + Fentanyl
Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. A patient controlled device prepared with 10 mcg/ ml fentanyl will be attached to all patients with a protocol included 10 mcg bolus without infusion dose, 10 min lockout time and 4 hour limit. Postoperative patient evaluation will be performed by an anesthesiologist blinded to the procedure.

Active Comparator: Group 20 = 20 ml of Erector spinae plane block group

In group ESPB, ESPB will be performed with patients in the lateral decubitus position while the surgical site up. US probe will be placed 2-3 cm lateral to the T4 transvers process. The block needle will be inserted cranio-caudal direction and then for correction of the needle 5 ml saline will be injected deep into the erector spina muscle fascia. Following confirmation of the correct position of the needle 20 ml %0.25 bupivacaine will be administered for block.

Drug: Bupivacaine + Fentanyl
Patients will be administered ibuprofen 400 mgr IV every 8 hours in the postoperative period. A patient controlled device prepared with 10 mcg/ ml fentanyl will be attached to all patients with a protocol included 10 mcg bolus without infusion dose, 10 min lockout time and 4 hour limit. Postoperative patient evaluation will be performed by an anesthesiologist blinded to the procedure.

Outcome Measures

Primary Outcome Measures

  1. Postoperative opioid consumption (need and demand as microgram) [Changes from baseline opioid consumption at postoperative 1, 2, 4, 8, 16 and 24 hours.]

    The primary aim is to compare postoperative opioid (fentanyl) consumption on patient controlled analgesia device. The parameters on PCA devices such as delivery and demand will be assessed

Secondary Outcome Measures

  1. Pain scores (Visual analogue scores-VAS) [Changes from baseline pain scores at postoperative 1, 2, 4, 8, 16 and 24 hours]

    Postoperative pain assessment will be performed using the VAS score (0 = no pain, 10 = the most severe pain felt). The VAS scores will be recorded
