Brief Summary

To meet the unmet need of better and safer pain relief for acute pain in the post-operative setting, a Vital-signs-integrated Patient-assisted Intravenous opioid Analgesia ("VPIA") Delivery System, with novel and intelligent software algorithms and specialised hardware was developed. In the previous project, the investigators have shown that this system has the potential to increase the safety and patient satisfaction with intravenous opioid analgesia. However, opportunities to develop more robust vital signs monitoring with the goal of ensuring continual and effective analgesia are identified. The primary aim of this proposal is to advance the development of technology (through new features and functionality) and perform clinical evaluation of the VPIA system with a larger sample size to show improvements in patient's satisfaction (pain relief) and robustness of system in terms of vital signs integration. Novel technology using adaptive vital signs controller, integrated with an infusion pump and single finger probe vital signs monitor system will be developed with the aim for commercialisation.

Outcome Measures

Primary Outcomes (1)

  • Incidence of a clinically significant bradypnoea

    The number of events of respiratory rate less than 8 per minute throughout the study period (when the patient is connected to the pump)

    Postoperative period (1 - 3 days)

Secondary Outcomes (4)

  • Postoperative pain score

    Postoperative period (1 - 3 days)

  • Patient satisfaction

    Postoperative period (1 day, after the use of pump)

  • Changes in Hospital Anxiety and Depression Scale (HADS) score

    Before surgery (1 day) and postoperative period (1-3 days)

  • EQ-5D-3L score

    Before surgery (1 day)

Study Arms (1)

VPIA analgesia

EXPERIMENTAL

VPIA pump will be connected to patients after surgery for up to three days. The vital signs (oxygen saturation, respiratory rate, heart rate) will be closely monitored when patients are using VPIA pump. Intravenous medication (morphine) will be given intravenously.

Device: VPIA pumpDrug: Morphine

Interventions

VPIA pumpDEVICE

The pump is a specially designed and manufactured infusion syringe pump for intravenous analgesia. It incorporates the VPIA study regimen to meet the specific requirements of the clinical trial. It is intended to be used only for delivering drugs intravenously.

Also known as: VPIA delivery system
VPIA analgesia

Intravenous medication used is morphine diluted in normal saline to a concentration of 1mg/ml. This is a standard dilution and are routine drugs used as standard of care.

Also known as: Morphine Sulphate
VPIA analgesia
