Effects of rhomboid intercostal and sub-serratus plane block on perioperative analgesic efficacy and diaphragm excursion in video-assisted thoracic surgery: a prospective, randomized controlled trial.

ABSTRACT:

Background

Rhomboid intercostal and sub-serratus plane (RISS) block is a novel nerve block technique that provides good analgesia, but overall research is scarce. This study aimed to investigate the effect of ultrasound-guided RISS block on postoperative analgesia and diaphragmatic excursion (DE) after video-assisted thoracic surgery (VATS) for lung cancer.

Methods

One hundred patients who underwent VATS lung resection participated in this study and were randomized to a RISS group (Group R) or a control group (Group C). Group R underwent ultrasound-guided RISS block with 0.25% ropivacaine hydrochloride 0.5 ml/kg immediately after surgery. Group C was given standard general anaesthesia, and patient-controlled intravenous analgesia (PCIA) was used in the postoperative period i
