Opioid-Free Combined Anesthesia With Spontaneous Breathing for VATS

Abstract

Non-tracheal intubated combined anesthesia with preserved spontaneous breathing significantly enhances the quality and speed of recovery post-VATS for patients undergoing lung nodule surgery. The "opioid-sparing strategy," which substitutes ketamine for opioids during surgery, not only provides effective analgesia but also protects perioperative lung function and reasonably prevents the occurrence of opioid-related adverse reactions; it also reduces medical costs and shortens the average hospital stay. However, the degree of benefit to patients lacks high-level clinical evidence. This study aims to comprehensively assess the effect of opioid-free combined anesthesia with preserved spontaneous breathing for VATS lung nodule surgery on postoperative rapid recovery from multiple aspects including postoperative lung function and pulmonary complications, pain, gastrointestinal function, nausea/vomiting, cognitive function, and depression/anxiety, intending to expand the dataset and application prospects in this field, and increase feasibility experience.
