Efficacy of Oxalidine and Sufentanil in Strabismus Correction: a Non Inferiority Trial

Since surgery involves fine manipulation of the ocular muscles, postoperative pain and oculocardiac reflex (OCR) are common clinical challenges. Therefore, anesthesia management should not only ensure adequate analgesia, but also minimize stress reactions and adverse reactions caused by surgical stimuli. At present, opioids such as sufentanil are widely used in the anesthesia scheme of such surgery because of its potent analgesia and stable hemodynamic characteristics. However, sufentanil may cause respiratory depression, postoperative nausea and vomiting (PONV) and other side effects, and its high lipid solubility may prolong the postoperative recovery time.

Oliceridine is a new selective μ - opioid receptor agonist. Compared with traditional opioids, it has the characteristics of biased activation of G protein pathway, which may provide effective analgesia and reduce the adverse reactions mediated by β - arrestin pathway (such as respiratory depression and gastrointestinal dysfunction). Recent studies have shown that oselidine has shown good safety and efficacy in postoperative analgesia, but its application in short ophthalmic surgery (such as strabismus correction) has not been fully explored.
