简要总结
A large number of studies have shown that patients feel more satisfied with hydromorphone in the pain management. and a systematic review found that hydromorphone may be better suited than morphine for titration of acute analgesia. However, current researches on intravenous opioid titration for cancer pain such as hydromorphone are relatively insufficient in China. Therefore, a prospective, multi-center, randomized controlled study is conducted to assess the efficacy and safety of comparing patient-controlled analgesia (PCA) versus non-PCA intravenous hydromorphone titration for severe cancer pain.
详细描述
The opioid dose for individual with cancer pain to provide adequate relief of pain with an acceptable degree of side effects is variable. Opioid titration is a process to obtain the tailored dose. Conventional titration is administered by a clinician or nurse. PCA is that patients control cancer pain by self-administration of intravenous opioids using programmable pump. The aim of our study is to evaluate the efficacy of PCA titration versus conventional titration intravenously for severe cancer pain (10-point numerical rating scale, NRS ≥ 7). Injectable Hydromorphone was selected as pharmaceutical analgesics, which works as well as morphine and oxycodone and had similar side effects.

研究组 & 干预措施
PCA IV Hydromorphone titration
PCA titration using programmable pump: bolus hydromorphone at 0.5mg (for opioid intolerance) or hydromorphone dose equivalent to 10% to 20% of the total opioid taken in the previous 24 hours with a lockout time 15 min (for opioid tolerance) was administered by the patients educated. No basal infusion was set in the pump.Repeated assessment of NRS score with a interval of 15 minutes until stable pain control. Then Repeated assessment of NRS score with a interval of 1 hour. The titration will be done on the patient's request (manipulation by the patient himelf/herself) in 24hrs.
干预措施: Hydromorphone (Drug)
PCA IV Hydromorphone titration
PCA titration using programmable pump: bolus hydromorphone at 0.5mg (for opioid intolerance) or hydromorphone dose equivalent to 10% to 20% of the total opioid taken in the previous 24 hours with a lockout time 15 min (for opioid tolerance) was administered by the patients educated. No basal infusion was set in the pump.Repeated assessment of NRS score with a interval of 15 minutes until stable pain control. Then Repeated assessment of NRS score with a interval of 1 hour. The titration will be done on the patient's request (manipulation by the patient himelf/herself) in 24hrs.
干预措施: PCA pump (Device)
non-PCA IV Hydromorphone titration
Non-PCA titration administered by a nurse or clinician: Initial hydromorphone doses were same with PCA titration. Repeated assessment of NRS score with a interval of 15 minutes until stable pain control. Then Repeated assessment of NRS score with a interval of 1 hour. The dose of hydromorphone increased by 50%-100% if pain unchanged or increased, or repeat same dose if pain decrease to 4-6. The titration will be done on the patient's request (manipulation by a nurse) in 24hrs.
干预措施: Hydromorphone (Drug)
结局指标
主要结局
The time of successful titration in 24 hours
时间窗: In 24 hours
The satisfied pain control was defined NRS pain score ≤ 3 at rest in at least 2 consecutive assessment (15 minutes interval). The time needed to successful titration was extended to achieve satisfied pain control again if NRS pain score ≥ 7 after satisfied pain control within 24 hours. The failure of successful titration was defined that satisfied pain control does not achieve within 24 hours.
次要结局
- The percentage of patients titrated successfully within 24 hours(Up to 24 hours)
- The percentage of patients titrated successfully within 60 minutes(Up to 60 minutes)
- The mean NRS pain score of 24 hours(Up to 24 hours)
- The total dose of hydromorphone titrated from start of titration to TST(Up to 24 hours)
- Improvement of patient symptoms(Up to 24 hours)
- Adverse Events(Up to 7 days)
- The total dose of hydromorphone titrated within 24 hrs(Up to 24 hours)
