Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy

to compare the ability of remimazolam to standard doses of propofol and ketamine to achieve successful tracheal intubation on the first attempt in patients at risk of aspiration of gastric contents in the operating room

Secondary objectives 2

  1. compare the efficacy of remimazolam, propofol and ketamine: quality of intubation condition, timing of tracheal intubation, mechanical or respiratory complication, cardiovascular complications.
  2. compare the tolerance of remimazolam, propofol and ketamine: episode of delirium in recovery room, episode of acute renal failure, death

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. proportion of patient with successful intubation at first attempt

Secondary endpoints 16

  1. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups:median intubation quality score (IDS-3) values, median Cormack-Lehane score values and median (POGO) score values
  2. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: median time between start of pre-oxygenation, administration of hypnotic (start of anesthetic induction), administration of NMB, initiation of first laryngoscopy and tracheal intubation (defined as the 6th capnography curve) (minutes)
  3. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: median value of heart rate, mean arterial pressure, SpO2 measured every minute from pre-oxygenation during the first 5 minutes after anesthetic induction
  4. n the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: percentage of patient with pulmonary aspiration of gastric contents
  5. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: percentage of patient with moderate (SpO2 ≤ 95%) or severe (SpO2 ≤ 80%) desaturation during the first 5 minutes after anesthetic induction
  6. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: median minimal value of SpO2 value during the first 5 minutes after anesthetic induction
  7. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: percentage of patients with major cardio-vascular events: major hemodynamic instability defined as mean arterial pressure ≤ 60mmHg (or ≤ 40% from the patient’s reference value) [16], heart rate < 45/mn, or systolic arterial pressure < 80 mmHg, cardiac arrythmia requiring pharmacological or external electric intervention or lasting more than 30 seconds
  8. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: percentage of patients with anaphylaxis reaction (Grade of anaphylaxis reaction)
  9. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: rates of vasopressor use and volume of intravenous fluids for vascular filling (from entry into the operating theatre to induction and from induction to recovery room)
  10. In the operating theatre (within 5 minutes after induction of anesthesia) compared between the three study groups: the total dose of hypnotic used during the first 5 minutes after anesthetic induction
  11. In the recovery room compared between the three study groups: postoperative Nu-DESC score median value
  12. In the recovery room compared between the three study groups: percentage of patient requiring sedative therapy in recovery room assigned with delirium
  13. Up to day 7 compared between the 3 groups: percentage of patient with major cardiovascular complications
  14. Up to day 7 compared between the three study groups: percentage of patient with postoperative acute renal failure at day 7
  15. Up to day 7 compared between the three study groups:intra-hospital mortality
  16. Up to day 7 compared between the three study groups: survival proportion at day 7
