This study will enroll 108 adults having surgery with a laryngeal mask airway. Researchers want to find the dose of tegileridine (combined with propofol) that prevents movement, coughing, and other reactions in 90% of patients. They will compare younger (18-65) and older (65+) gr…

This study tests whether a specific nerve block, called an external oblique intercostal block, can reduce pain and the need for opioid painkillers after laparoscopic gallbladder removal. Fifty-six adults scheduled for this surgery will be randomly assigned to receive either the n…

This study compared two painkillers—oliceridine and sufentanil—given alongside propofol sedation during gastrointestinal endoscopy. The goal was to see if oliceridine causes fewer episodes of low blood oxygen (hypoxemia) than the standard drug. Over 500 adults participated, and r…

This study tested whether adding a dexmedetomidine nasal spray to the usual sedative propofol could reduce breathing problems during ERCP, a procedure to treat bile duct issues. 180 adults were split into three groups: one got the nasal spray plus propofol, another got dexmedetom…

This study aims to find the 90% effective dose of tegileridine, a painkiller, when combined with propofol for sedation during painless gastroscopy. Researchers will test different doses in young (18-65) and elderly (65+) adults to see which dose best prevents movement, coughing, …

This study tested different doses of oliceridine, a painkiller, to find the amount that best prevents sudden rises in blood pressure and heart rate when a breathing tube is placed during anesthesia. Researchers enrolled 58 adults having elective surgery and adjusted doses based o…
