Rhomboid Intercostal and Subserratus Plane Block vs Erector Spinae Plane Block in Video-Assisted Thoracoscopic Surgery

To compare the rhomboid intercostal subserratus plane block with the erector spinae plane block regarding their analgesic efficacy and effects on respiratory function for patients undergoing video-assisted thoracoscopic surgery.

About this study

Video-assisted thoracoscopic surgery (VATS) can be very painful and may lead to complications such as prolonged stays in intensive care, thromboembolic complications due to lack of early mobilization, chronic acute pain, and delirium if adequate analgesia is not provided. Therefore, using thoracic epidural, paravertebral, or regional blocks as part of multimodal analgesia is recommended to provide effective pain relief.

This study aims to compare the effects of the erector spinae plane block (ESP) and rhomboid intercostal subserratus plane block (RISS) on postoperative analgesia and the improvement of respiratory parameters in patients undergoing VATS.

The primary objective is to evaluate total analgesic consumption in the first 24 hours postoperatively. Secondary objectives include assessing active and dynamic pain scores, triflow performance, complications, and the length of hospital stays.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients who will undergo VATS
  • Who agrees to participate
  • American Society of Anesthesiologists (ASA) physical status I, II, and III
  • Elective surgery
  • Age between 18 and 80 years

Exclusion criteria

  • Local anesthetic allergy
  • Who disagrees to participate
  • ASA physical status IV and V
  • Emergency surgery
  • Hemorrhagic disease
  • Thoracic vertebrae deformity
  • Thoracic vertebrae surgery

Treatment and study plan

ESP block group

Procedure

ESP blocks are performed for patients undergoing VATS.

RISS block group

Procedure

RISS blocks are performed for patients undergoing VATS.

Primary outcomes

  1. Opioid consumption

    Time frame: Postoperative first 24 hours.

    Total opioid consumption within the first 24 hours in the postoperative period.

Secondary outcomes

  1. Dynamic pain score

    Time frame: Postoperative first 24 hours.

    Postoperative pain scores during coughing and deep breathing are measured on a 10 cm scale, where "0" indicates no pain and "10" indicates the worst pain ever.

  2. Resting pain score

    Time frame: Postoperative first 24 hours.

    Postoperative pain scores during rest are measured on a 10 cm scale, where "0" indicates no pain and "10" indicates the worst pain ever.

  3. Pulmonary functions

    Time frame: Postoperative first 24 hours.

    Pulmonary functions are assessed using Triflow performance. Postoperative Triflow numbers (whether 1, 2, or 3 balls can be raised) for the patients are recorded.

  4. Complications

    Time frame: Through study completion, an average of 1 year

    Complications regarding regional blocks and surgery (such as hematoma, pulmonary complications) are recorded.

  5. Hospital stay time

    Time frame: Perioperatively

    The length of hospital stay is recorded.
