Not Applicable

Recruiting

• Conditions: Video Assisted Thoracoscopic Surgery; Regional Block for Pain Control; Regional Blocks; Pulmonary Functions

• Registration Number: NCT07011069
• Lead Sponsor: Bursa City Hospital

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Opioid consumption	Postoperative first 24 hours.	Total opioid consumption within the first 24 hours in the postoperative period.

Secondary Outcome Measures

Name	Time	Method
Dynamic pain score	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.
Resting pain score	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.
Pulmonary functions	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.
Complications	Through study completion, an average of 1 year	Complications regarding regional blocks and surgery (such as hematoma, pulmonary complications) are recorded.
Hospital stay time	Perioperatively	The length of hospital stay is recorded.
