PSB and Recto-İC in sternotomy

Details and patient eligibility

About

The aim of this study was to investigate the effectiveness of the combination of Superficial Parasternal Block and Recto-Intercostal Fascial Plane Block in patient groups undergoing cardiac surgery via sternotomy by evaluating postoperative pain scores and analgesic consumption.

Full description

Ten patients received a combination of parasternal block and recto-intercostal fascial plane block as an intervention. Patients received bilateral parasternal block and recto-intercostal fascial plane block with 0.25% bupivacaine (total volume 60 ml) in the operating room before surgery. All blocks will be performed after general anesthesia induction, before skin incision. All patients included in the study will be given 50 mg dexketoprofen and 1 g paracetamol intravenously (i.v.) 10 minutes before skin closure. All patients will be given 3x1 g iv paracetamol and 2x50 mg dexketoprofen within the first 24 hours postoperatively. Numerical rating scale (NRS) was used to assess pain at the 1st, 6th, 12th, 18th and 24th hours after surgery. Total morphine consumption was calculated using a patient-controlled analgesia (PCA) device. Tramadol was planned as rescue analgesic medication (maximum dose: 300 mg/day).

Description:

Superficial PSB is performed with the patient in the supine position using a high-frequency linear USG probe. The probe is placed longitudinally 2 cm lateral to the sternal border to visualize the T2-T4 intercostal space and to identify the pectoralis major muscle, intercostal muscle, and pleura. 10 ml of 0.25% bupivacaine local anesthetic is administered between the pectoralis major and intercostal muscle using an in-plane approach with a 100 mm needle. In addition, a Recto-Intercostal Fascial Plane Block is performed with a high-frequency linear USG probe. The probe is placed 2-3 cm lateral to the xiphoid so that the rectus abdominis muscle and 6-7th cartilages are visualized. The needle is advanced to the plane between the costal cartilage and the rectus abdominis muscle using the in-plane technique and 1-2 ml of saline is injected. After observing the spread to the target plane, 20 ml of 0.25% bupivacaine is applied. The same process is repeated bilaterally.
