Clinical trials

This clinical trial aims to understand whether a visual double-lumen intubation tube can improve the first-attempt success rate and reduce complications compared to a standard double-lumen tube. The trial primarily aims to answer the following questions: Does a double-lumen tube improve the first-attempt success rate? Does a visual double-lumen tube reduce the likelihood of obstruction of the right upper lobe bronchial opening? Does a visual double-lumen tube require fewer adjustments during surgery? Do patients with visual double-lumen tubes experience fewer perioperative complications compared to those with standard double-lumen tubes? Participants will: Use a visual double-lumen tube partially and a standard double-lumen tube partially. Record the perioperative status of all patients.

Hypoxia is the most common adverse reaction during sedation outside the operating room.Exploring novel drug combinations to reduce the incidence of hypoxia during sedation in patients undergoing transvaginal oocyte retrieval procedures enhances patient safety and lowers perioperative adverse event rates. This multicenter, prospective, randomized, controlled clinical study will compare the hypoxia incidence rate of the remimazolam-alfentanil combination against the commonly used propofol-alfentanil combination.
