Brief Summary

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).

Conditions

Postoperative Pain Management

Keywords

rhomboid intercostal plane block; serratus posterior superior intercostal plane block; vats; video-assisted thoracoscopic surgery; postoperative pain

Outcome Measures

Primary Outcomes (1)

• 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.

  postoperative 24 hours

Study Arms (2)

SPSIP BLOCK

ACTIVE COMPARATOR

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.

Procedure: SPSIP block

RIB BLOCK

ACTIVE COMPARATOR

Arm Description:Rhomboid intercostal plane block procedure, 10% povidone-iodine will be used for skin cleansing. The 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.

Procedure: RIB BLOCK

Interventions

RIB BLOCK PROCEDURE

30 mL of 0.25% bupivacaine was injected deep to the rhomboid intercostal spinal block.

RIB BLOCK

SPSIP block PROCEDURE

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.
