Recto-Intercostal Fascial Plane (RIFP) Block in Laparoscopic Cholecystectomy Patients (RIFPB)

November 24, 2025 updated by: Ayse Ince, Istanbul Medipol University Hospital

Evaluation of the Effectiveness of Ultrasound-Guided Recto-Intercostal Fascial Plane (RIFP) Block in Postoperative Analgesia Management in Patients Undergoing Laparoscopic Cholecystectomy

Ultrasound-guided Recto-Intercostal Fascial Plane (RIFP) Block is performed by injecting local anesthetic deep between the 7th rib and the costochondral aspect of the rectus muscle. It provides blockage of both the anterior and lateral cutaneous branches of T6-T10/11 and analgesia of the sternum, epigastrium, and upper abdomen (1).

Studies show that RIFP block is effective for postoperative analgesia, sternum revision, and cardiac surgery. However, its effect on patients undergoing laparoscopic cholecystectomies has not been studied yet. The investigators hypothesize that RIFP block performed in laparoscopic cholecystectomies would reduce postoperative rescue analgesic use and postoperative opioid consumption in the first 24 hours after surgery.

Study Overview

Detailed Description

Cholecystectomy is the most common abdominal surgical procedure performed in developed countries and is usually performed laparoscopically. Many factors play a role in the pain that develops after laparoscopic cholecystectomy and it has both somatic and visceral components. Phrenic nerve irritation as a result of CO₂ insufflation into the peritoneal cavity, abdominal distension, tissue trauma, trauma due to gallbladder removal, sociocultural differences, and individual factors are the factors that play a role in the emergence of this pain. Postoperative pain is an acute pain that is accompanied by an inflammatory process that occurs due to surgical trauma and gradually decreases with tissue healing. Pain in the postoperative period in patients undergoing laparoscopic cholecystectomy is a serious problem that reduces patient comfort and delays the patient's return to normal life after surgery. Effective postoperative pain management prevents many effects such as shallow breathing and delayed mobilization.

RIFPB performed with ultrasound (US) guidance is a new abdominal plane block. The rectus muscle attaches to the cartilage of the 7th rib in the epigastrium on the cranial side. Injecting local anesthetic between the 7th rib and the rectus muscle provides effective analgesia in the sternal, epigastric, and upper abdominal areas. It can be used as a complementary block for thorax, and a stand-alone technique for the abdomen. RIFPB provides analgesia at T6-T10/11 dermatome levels for lateral and medial cutaneous branches. Visualizing son anatomy with US is easy and the spread of local anesthetic can be easily detected. According to the literature, there are case series reporting RIFPB to be effective in cardiac surgery, and sternum revision surgery, both for postoperative analgesia management and as a sole anesthetic method alone. The investigators hypothesize that this block can provide effective postoperative analgesia in laparoscopic cholecystectomy operations due to its mechanism of action. This study aims to evaluate the effectiveness of USG-guided RIFB block for primary postoperative analgesia management after laparoscopic cholecystectomy surgery.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group R = RIFP Block group
RIFP block will be performed and standard postoperative pain management protocols will be applied.
After aseptic conditions are ensured, with high-frequency linear US probe (11-12 MHz, Vivid Q) and a 22-G 80-mm needle (Pajunk Sonoplex Nanoline Stim Cannula, Germany) bilateral block will be applied to Group R. As the patient is in supine position, the USG probe is placed in transverse plane on the sternum and will be directed downwards and laterally and rotated to determine the xiphoid and just below the rectus abdominis muscles. Costal cartilage and rectus abdominis muscle sonographically will be shown. This region corresponds to the 3-4 cm lateral and 3-4 cm caudal region of the xiphoid. Using the in-plane technique, the block needle will be advanced in the caudal-cephalic direction, and 5 ml saline will be injected into the area between the rectus muscle and costal cartilage to verify the block location. 30 ml of 0.25% bupivacaine (Buvacaine, Polifarma ®) will be injected to each side, which corresponds to 60 ml total local anesthetic-saline mixture in Group R.

Ibuprofen 400 mg (Ibuprofen, Polifarma ®) and tramadol 100 mg (Contramal, Abdi İbrahim ®) IV single bolus dose will be given 20 minutes before the end of the surgical procedure for postoperative analgesia.

NRS scores at rest and while moving will be evaluated and recorded and if the NRS score is ≥ 4, meperidine 0,5 mg/kg (Aldolan®) IV will be administered as a rescue analgesic.

Active Comparator: Group K = Control group
Standard postoperative pain management protocols will be applied. No plane block will be applied.

Side effects and complications
Time Frame: Side effects and complications will be evaluated and recorded at 1, 3, 6, 12,18, and 24 hours postoperatively
Side effects such as nausea, vomiting, sedations, and complications (hematoma, pneumothorax, etc.) will be recorded.
Side effects and complications will be evaluated and recorded at 1, 3, 6, 12,18, and 24 hours postoperatively
Compare postoperative pain scores (Numeric Rating Scale - NRS scores)
Time Frame: NRS scores at rest and while moving will be evaluated and recorded at 1, 3, 6, 12,18, and 24 hours postoperatively.

The numeric rating scale (NRS) is a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-10 scale, with zero meaning "no pain" and 10 meaning "the worst pain imaginabl. Higher pain scores mean worse outcome.

NRS scores at rest and while moving will be evaluated and recorded.

NRS scores at rest and while moving will be evaluated and recorded at 1, 3, 6, 12,18, and 24 hours postoperatively.
