Observation and Study on the Application of Different Analgesic Regimens in Critically Ill Patients Without Mechanical Ventilation

Pain management is a common treatment measure in the Intensive Care Unit (ICU). Due to their underlying diseases and invasive treatments, patients often experience discomfort and pain, leading to agitation, unplanned extubation, patient-ventilator asynchrony, and even neuroendocrine-immune dysregulation, sympathetic overexcitation, and impaired organ function. Analgesic therapy can reduce patient stress and increase comfort, making it an essential treatment for critically ill patients. However, it may also cause adverse effects such as respiratory depression and decreased gastrointestinal motility. There is currently no consensus on how to precisely implement analgesic therapy in non-mechanically ventilated critically ill patients to reduce adverse effects like respiratory depression.This prospective observational study will enroll non-mechanically ventilated critically ill patients receiving analgesic therapy. It will observe different analgesic strategies, including factors such as pain assessment status, drug types, duration of analgesia, and cumulative drug doses, to understand their effects and adverse reactions in non-mechanically ventilated patients. The study aims to explore optimized analgesic treatment regimens and provide evidence-based support for implementing precise analgesic therapy in clinical practice.
