Brief Summary

This is a closed-loop system which is embodied in a novel and intelligent algorithm that takes into account patients' vital signs. The system allows better and responsive titration of personalized pain relief together with non-invasive physiological monitoring that measures oxygenation, breathing and heart rate continuously.

Outcome Measures

Primary Outcomes (1)

  • Number of episodes of breech in safety thresholds

    Any episode of oxygen saturation \<95%, Heart rate \<60 bpm or Respiratory rate \<8 breaths/min

    2 days

Secondary Outcomes (1)

  • Pain scores

    2 or 3 days

Study Arms (1)

VPIA analgesia system

EXPERIMENTAL

Vital-signs-integrated patient-assisted intravenous opioid analgesia system (VPIA). The vital signs (oxygen saturation, respiratory rate, heart rate) will be close monitored when patients is using VPIA pump. The drug used is intravenous morphine (1mg per milligram) with bolus of 1 mg.

Device: VPIA analgesiaDrug: Morphine

Interventions

Recruited subjects will be given a VPIA device containing 1mcg/ml of morphine. Morphine will be administered via an intravenous infusion line with an anti-reflux valve to ensure precise drug administration and no backflow.

Also known as: VPIA delivery system
VPIA analgesia system

Recruited subjects will be given a VPIA device containing 1mcg/ml of morphine. Morphine will be administered via an intravenous infusion line.

Also known as: Morphine-VPIA
VPIA analgesia system
