Among the 26 studies in Pain, Postoperative by Cumhuriyet University, from their registry updates:
This study aimed to compare rhomboid intercostal plane block and serratus posterior superior intercostal plane block (SPSIPB) to determine the most suitable technique for maintaining postoperative analgesia in video-assisted thoracoscopic surgeries (VATS).
Patients were randomly allocated into two groups: RIB and SPSIPB. All patients received postoperative paracetamol and dexketoprofen, and intravenous tramadol hydrochloride was administered via patient-controlled analgesia. Postoperative static and dynamic NRS scores, total tramadol consumption, side effects, and the need for additional analgesia were monitored and recorded at regular intervals. Primary outcome was NRS scores and secondary outcome was total tramadol consumption.
Block Techniques
All blocks were performed following surgical closure, prior to extubation, with the patient in lateral decubitus and the skin prepared with 10% povidone-iodine.
RIB:Rhomboid intercostal plane block procedure is performed using a high-frequency linear ultrasound probe. First, the rhomboid and intercostal muscles are located in the area called the auscultation triangle, at the level of thoracic 4-5 o'clock. A needle, visible on ultrasound, is advanced between the rhomboid and intercostal muscles using an in-plane technique. After aspiration is performed to ensure no blood or air is present, a total of 30 ml of 0.25% bupivacaine will be injected between the two muscle planes. The rhomboid intercostal plane block creates sensory paresthesia (sensory numbness) in a dermatomal region between T3 and T9 o'clock.
SPSIPB: The USG probe was placed 2-3 cm medial to the scapular spine to visualize the trapezius, rhomboid major, and serratus posterior superior muscles. At the level of the 2nd-3rd ribs, a needle was advanced into the plane between the serratus posterior superior muscle and the rib. After confirming negative aspiration, 30 mL of 0.25% bupivacaine was injected.
All blocks were performed unilaterally, targeting the surgical hemithorax.
Postoperative Analgesia and Assessments
Twenty minutes before extubation, all patients received 1 g IV paracetamol and 50 mg IV dexketoprofen. In the recovery room, patient-controlled analgesia (PCA) with IV tramadol hydrochloride was initiated (4 mg/mL concentration, 10 mg bolus, 20-minute lockout, maximum 3 boluses/hour).
Postoperative NRS scores (static at rest and dynamic during movement or coughing) were recorded at 0, 1, 2, 6, 12, 18, and 24 hours. The first NRS assessment (0 hour) was performed when the patient achieved an Aldrete score of 9. If NRS ≥ 4, an additional 50 mg IV tramadol was administered. Additional analgesic consumption was recorded. Side effects such as nausea, vomiting, and pruritus were documented.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Arm Description: The USG probe was placed 2-3 cm medial to the scapular spine to visualize the trapezius, rhomboid major, and serratus posterior superior muscles. At the level of the 2nd-3rd ribs, a needle was advanced into the plane between the serratus posterior superior muscle and the rib. After confirming negative aspiration, 30 mL of 0.25% bupivacaine was injected. The block was performed unilaterally, targeting the surgical hemithorax.

30 mL of 0.25% bupivacaine was injected deep to the rhomboid intercostal spinal block.
The USG probe was placed 2-3 cm medial to the scapular spine to visualize the trapezius, rhomboid major, and serratus posterior superior muscles. At the level of the 2nd-3rd ribs, a needle was advanced into the plane between the serratus posterior superior muscle and the rib.

NUMERICAL RATING SCORE(NRS)
Numerical rating scale is used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean "the most severe pain that the patient ever had". 0 point means "there is no pain." Higher scores mean worse outcome.
Time frame: postoperative 24 hours
