About this study
the investigators conducted a randomized controlled trial in respiratory intensive care unit (RICU) of Assiut University Hospital. COPD patients admitted to RICU were included. Exclusion criteria include: Marked renal impairment, Liver cell failure, neurological disorders, age <18 or >70 and pregnancy.
Patients were randomly allocated to two groups. Midazolam was used for sedation in both groups. Richmond agitation-sedation score (RASS) was used to monitor level of sedation or agitation. Control group received daily interruption of sedation. intervention group managed by no-sedation strategy.
Primary outcome measure: changes in PaCO2 Secondary outcome measures include: changes in PH, heart rate, mean arterial blood pressure, respiratory rate, P0.1 and NIF.

The researchers conducted a randomized controlled trial in respiratory intensive care unit (RICU) of Assiut University Hospital. COPD patients admitted to RICU were included. Exclusion Criteria include: Marked renal impairment (creatinine > 2mg/dl), Liver cell failure (Bilirubin> 3mg/dl), neurological disorders, age <18 or >70 and pregnancy.
Patients were randomly allocated to two groups. Midazolam was used for sedation in both groups. Richmond agitation-sedation score (RASS) was used to monitor level of sedation or agitation. Control group received daily interruption of sedation. After intubation, patients received IV infusion of midazolam, gradually increasing dose till RASS reached -4 or -5. Infusion stopped at 7:00 AM. If the patient is awake no need for resuming infusion. If signs of discomfort occurred, infusion resumed at half of the prior dose, targeting conscious sedation (RASS 0: -3) Intervention group were managed by no-sedation strategy. Patients received bolus doses of midazolam only when needed, after atrial to control agitation by correcting the underlying cause. If the patient needed more than 3 bolus doses , IV infusion of midazolam was given by the daily interruption protocol as in the control group. No crossover was allowed between groups. Analysis was done by intension-to-treat principle.
Follow up arterial blood gas sampling was done baseline at intubation. 1hr., 2hrs., 12hrs., 24hrs. and 48hrs. after intubation. Recording of clinical monitoring parameters (hear rate, mean arterial blood pressure, respiratory rate) was done at the same intervals. Airway occlusion pressure (P0.1) and negative inspiratory force (NIF) were measured 48 hours after intubation to test affection of respiratory muscles in both groups.
Primary outcome measure: changes in PaCO2 Secondary outcome measures include: changes in PH, heart rate, mean arterial blood pressure, respiratory rate, P0.1 and NIF.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MidazolamDrug
| Study group | Role | What they receive |
|---|---|---|
| Daily interruption of sedation (control group) | Experimental | Control group received daily interruption of sedation. After intubation, patients received IV infusion of midazolam. 1-2 mg / hour with increments 1-2 mg/hr gradually increasing dose till RASS reached -4 or -5. Infusion stopped at 7:00 AM. If the patient is awake no need for resuming infusion. If signs of discomfort occurred, infusion resumed at half of the prior dose, targeting conscious sedation (RASS 0: -3) Receives: Drug: Midazolam |
| No sedation | Experimental | Intervention group were managed by no-sedation strategy. Patients received bolus doses of midazolam (1-5 mg) only when needed, after atrial to control agitation by correcting the underlying cause. If the patient needed more than 3 bolus doses , IV infusion of midazolam was given by the daily interruption protocol as in the control group. No crossover was allowed between groups. Analysis was done by intension-to-treat principle. Receives: Drug: Midazolam |

Questions about this trial
What is this clinical trial studying?
A study testing Midazolam in people with Sedation in Critically Ill COPD Patients, run by Assiut University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ventilation affection (time frame: 48 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03678532, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2018.
