MTP block vs ESP block for pain control after VATS

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, double-blind study compares two ultrasound-guided fascial plane blocks—midpoint transverse process to pleura (MTP) block and erector spinae plane (ESP) block—for postoperative analgesia in adults undergoing elective VATS. Each participant receives a single injection of ropivacaine 0.375% at the T4–T5 level after induction of general anesthesia. The primary outcome is total fentanyl consumption via patient-controlled analgesia in the first 24 hours postoperatively, with secondary outcomes including pain scores at multiple time points and time to first analgesia. All patients receive standardized general anesthesia, multimodal analgesia, and identical postoperative fentanyl PCA. The study is conducted at RS Ngoerah in Denpasar, Indonesia, sponsored by Udayana University.
