Method and system for adjusting infusion parameters in combination with pain assessment, and pump withdrawal prompting method

A method and a system for adjusting infusion parameters in combination with a pain assessment, and a pump withdrawal prompting method and a smart analgesic pump having a pump withdrawal prompting function. A method for automatically adjusting infusion parameters in combination with a pain assessment, the method comprising: after an infusion system triggers an automatic increase or decrease signal, performing a pain assessment before the infusion parameters are changed, so as to determine whether the change of the infusion parameters of this time actually reflects insufficient analgesia or excessive analgesia, and then increasing infusion, decreasing infusion or infusion maintaining the original parameters in combination with the increase or decrease signal and the result of the pain assessment. Before adjusting the infusion parameters, the method and system introduce a pain assessment, improving the accuracy and reliability of the analgesic pump automatically changing the infusion parameters. By introducing the pain assessment, the invention can more accurately determine whether the current situation actually complies with a pump withdrawal condition, so as to reduce the unnecessary usage time of analgesic medications, and reduce the use of medications and side effects.
