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. These two techniques may have different analgesic profiles with respect to somatic and visceral pain. The primary objective is to evaluate the incidence of chest tube-site somatic pain at postoperative hour 2. Secondary objectives include the incidence of visceral pain, total analgesic consumption in the first 24 hours postoperatively, assessing resting and dynamic pain scores, triflow performance, complications, and length of hospital stay.

Interventions

ESP blocks are performed for patients undergoing VATS.

PROCEDURERISS block group

RISS blocks are performed for patients undergoing VATS.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of chest tube-site somatic painAt postoperative hour 2Proportion of participants with localized pain at the chest tube insertion site, elicited by palpation or chest tube manipulation. Somatic pain was recorded as present or absent.

Secondary

MeasureTime frameDescription
Dynamic pain scorePostoperative first 24 hours.Postoperative pain scores during coughing and deep breathing are measured on a 11 cm scale, where "0" indicates no pain and "10" indicates the worst pain ever.
Opioid consumptionPostoperative first 24 hours.Total opioid consumption within the first 24 hours in the postoperative period.
Resting pain scorePostoperative first 24 hours.Postoperative pain scores during rest are measured on a 11 cm scale, where "0" indicates no pain and "10" indicates the worst pain ever.
Pulmonary functionsPostoperative 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.
ComplicationsFrom block administration to hospital discharge.Complications regarding regional blocks and surgery (such as hematoma, pulmonary complications) are recorded.
Hospital stay timeFrom surgery to hospital discharge.The length of hospital stay is recorded.
Incidence of visceral painAt postoperative hour 2Proportion of participants reporting deep, poorly localized intrathoracic pain not confined to the incision or chest tube insertion site. Pain was recorded as present or absent.
