Ketamine-propofol Versus Ketamine Alone for Procedural Sedation in Adults

"K= Kétamine P= Propofol RSS= Ramsay Sedation Score~At t0: 0.5 mg/kg of K (0.1 ml/kg of 5 mg/ml K) followed by 0.5 mg/k of P (0.1 ml/kg of 5 mg/ml P).~At t0 + 4 min, if needed to obtain an optimal sedation (RSS of 4 or 5): 0.25 mg/kg of K (0.05 ml/kg of 5 mg/ml K) followed by 0.25 mg/kg of P (0.05 ml/kg of 5 mg/ml P).~At t0 + 8 min, if needed to obtain an optimal sedation (RSS of 4 or 5): 0.25 mg/kg of K (0.05 ml/kg of 5 mg/ml K) followed by 0.25 mg/kg of P (0.05 ml/kg of 5 mg/ml P).~At t0 + 12 min, if maximal doses have been reached (1 mg/kg of K + 1 mg/kg of P) but the optimal sedation has not been obtained, the procedural sedation will be recorded as a failure in the analysis, and the patient will receive another procedural sedation product (at the discretion of the caregiver)."

"K= Ketamine I= Intralipid placebo~At t0: 1 mg/kg of K (0.1 ml/kg of 10 mg/ml K), followed by 0.1 ml/kg of I (physical placebo of propofol in the other arm).~At t0 + 4 min, if needed to obtain an optimal sedation (Ramsay Sedation Score of 4 or 5): 0.5 mg/kg of K (0.05 ml/kg of 10 mg/ml K), followed by 0.05 ml/kg of I.~At t0 + 8 min, if needed to obtain an optimal sedation (Ramsay Sedation Score of 4 or 5): 0.5 mg/kg of K (0.05 ml/kg of 10 mg/ml K), followed by 0.05 ml/kg of I.~At t0 + 12 min, if maximal doses have been used (2 mg/kg of K) but the optimal sedation has not been obtained, the procedural sedation will be recorded as a failure in the analysis, and the patient will receive another procedural sedation product (at the discretion of the caregiver)."
