Study summary

Most critically ill patients encounter pain and distress from acute illness, medical procedures and devices as well as routine care in the intensive care units (ICU). Opioids are principal analgesics that alleviate moderate to severe pain and facilitate patients to co-operate the course of treatment. However, prolong administration of opioids especially in mechanically ventilated patients can cause withdrawal symptoms if analgesics are rapidly weaning or acutely disruption. The opioid withdrawal symptoms (OWS) are well reported in critically ill children that cause discomfort and prolong weaning from mechanical ventilation. Weaning opioids and treatment of withdrawal symptoms are needed in order to decrease ventilator days, ICU and hospital length of stay. Conversely, there is lack of knowledge about incidence, clinical presentation, time course and appropriated assessment tool for withdrawal detection. Therefore, we conduct the study to explore an incidence of OWS, to identify factors associated OWS, to establish the assessment tool for OWS, and to report efficacy of the pharmacological treatment for OWS, in adult critically ill patients.

Read the detailed description

The primary objective of the study is to explore incidence of OWS in adult critically ill patients. The secondary objectives are 1) to identify factor associated OWS, 2) establish the assessment tool for OWS for adults and 3) to report efficacy of the pharmacological treatment in OWS in adults patients.

Study population

Intensive care units

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age ≥18 years
  • On mechanical ventilator at least 24 hours
  • Received continuous infusion of opioid at least 24 hours
  • Patient or legal surrogate who is willing and able to provide written and comply with all protocol requirements

Exclusion criteria

Exclusion Criteria:

  • Severely disturbed behavior pattern on account of underlying neurological disease (status epilepticus, encephalopathy, head trauma, brain injury, spinal cord injury)
  • Preexisting psychiatric diagnosis
  • Substance abuse prior to ICU admission
  • Chronic alcohol drinking
  • Pregnancy
  • End-of-life care
  • Death during ICU admission or during opioid IV infusion
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 9, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
