What this trial studies

This is a multicenter, randomized, double-blind, controlled trial comparing fospropofol disodium to propofol for painless endoscopic diagnosis and treatment. Eligible patients (age 50–65, weight 40–65 kg, ASA I–II) are assigned by computer-generated randomization to either the fospropofol group or the propofol group, with drug administration performed by designated anesthesiologists. The study measures anesthesia induction and intraoperative respiratory and circulatory stability, rates of hypoxemia and adverse cardiovascular events, recovery profile, and common adverse effects such as injection pain and postoperative nausea and vomiting. The planned duration of the project exceeds two years and is conducted at multiple hospitals in Jiangsu Province, China.

Who should consider this trial

Good fit: Adults aged 50–65 years, weighing 40–65 kg, with ASA physical status I–II who are scheduled for painless gastrointestinal endoscopy or colonoscopy and can give informed consent are ideal candidates.

Not a fit: Patients with obesity or obstructive sleep apnea, difficult airways, acute respiratory infections, significant liver or kidney impairment, abnormal cardiac function, drug allergies, or other listed exclusion criteria are unlikely to benefit and are excluded.

Why it matters

Potential benefit: If successful, fospropofol could offer more stable anesthesia with fewer respiratory and cardiovascular complications, less injection pain, and faster recovery for patients undergoing painless endoscopy.

How similar studies have performed: Previous clinical work with fospropofol for procedural sedation has shown some benefits such as reduced injection pain and comparable sedative efficacy to propofol, but its use is less widespread and data remain limited.
