Study summary

Hydromorphone has a clear analgesic effect, and has few advantages in respiratory depression and gastrointestinal motility. The study will further explore the continuous pumping-dose of hydromorphone for ICU non-mechanical ventilation patients and monitor its effective plasma concentration as well as evaluates the safety and effectiveness of hydromorphone for ICU non-mechanical ventilation patients.
