Clinical Trial Summary

The aim of this prospective, randomized, active control, double blinded study is to assess the effect and safety of continuous infusion nefopam in mechanically ventilated ICU patients compared to standard of care. It is being hypothesized that continuous infusion nefopam will reduce opioid use with acceptable safety profile compared to standard of care.


Description:

Pain is defined as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage". Critically ill patients experience pain at rest and during standard caring procedures. Arterial catheter insertion, chest tube removal, wound drain removal, wound care, and turning are associated with the greatest increased pain intensity. Pain have short and long-term sequelae on critically ill patients. Short-term sequelae include impaired tissue oxygenation, impaired wound healing, and impaired immune functions. Long-term sequelae include chronic pain, Post-traumatic stress disorder (PTSD) symptoms, and a lower health-related quality of life. The gold standard for pain assessment is patient's self-report of pain. For critically ill able to self-report pain the 0-10 numeric rating scale in a visual format (NRS-V) is the best to use. Unfortunately, a lot of critically ill patients are unable to communicate and self-report pain. So, using behavioral pain scales are suitable in this type of patients, Critical care pain observation tool (CPOT) demonstrates validity and reliability for monitoring pain in critical ill adult patient who are unable to self-report pain and in whom behaviors are observable. The 2018 Pain, Agitation/sedation, Delirium, Immobility, and Sleep disruption (PADIS) guideline panel suggests "using an assessment-driven, protocol-based, stepwise approach for pain and sedation management in critically ill adults" and state as a good practice statement "critically ill adults should be regularly assessed for delirium using a valid tool". Opioids are a cornerstone in the management of pain in critically ill patient, but have a lot of negative consequences including constipation, urinary retention, bronchospasm, over-sedation, respiratory depression, hypotension, nausea, truncal rigidity, delirium, and immunosuppression. Also, they contribute to vasodilatation and hypotension which lead to increased resuscitation fluids volume in critically ill patient. "Multi-modal analgesia" also known as "balanced analgesia" approach via using non-opioids adjuvant or in replacement of opioids to target different pain pathways leads to optimizing analgesia and reducing opioids consumption. In France, the second most prescribed non-opioids in mechanically ventilated intensive care unit (ICU) patient is nefopam. Nefopam is a non-opioid, non-steroidal centrally acting analgesic, although the exact mechanism of action poorly understood, analgesic activity is thought to be via inhibiting dopamine, norepinephrine, serotonin reuptake. Nefopam was non-inferior to fentanyl for pain control in patients undergoing elective cardiac surgery without increase in adverse effects. Nefopam has a fentanyl sparing effect up to 50% in patients underwent laparoscopic total hysterectomy. The 2018 PADIS guideline panel made a conditional recommendation for using "nefopam (if feasible) either as an adjunct or replacement for an opioid to reduce opioid use and their safety concerns for pain management in critically ill adults". Therefore, the aim of this prospective, randomized, active control, double blinded study is to assess the effect and safety of continuous infusion nefopam in mechanically ventilated ICU patients compared to standard of care. It is being hypothesized that continuous infusion nefopam will reduce opioid use with acceptable safety profile compared to standard of care.

Intervention

Drug:
Nefopam
Nefopam will be administered as an initial dose of 20 mg IV dose infused over 15 minutes then, as continuous infusion of 5 mg/hr for 24 hours.
Standard of care in the ICU for assessment and management of pain, sedation, and delirium.
In our protocol we use analgiosedation approach (an opioid is used before a sedative to reach the sedation goal), targeting light sedation using richmond agitation sedation scale (RASS) score -1 to 0, and assess delirium using confusion assessment method for the ICU (CAM-ICU).
