Study Arms:
- placebo (Type: PLACEBO_COMPARATOR): To do procedural sedation and analgesia in this group, the patients will receive 2 intravenous injections of distilled water (one 2 ml and the other 0.05 cc/kg) 5 minutes before receiving a sedative dose of 1 mg/kg IV ketamine.
- midazolam (Type: EXPERIMENTAL): To do procedural sedation and analgesia in this group, the patients will receive 2 intravenous injections. one will be 2 ml of distilled water and the other 0.05 mg/kg midazolam, 5 minutes before receiving a sedative dose of 1 mg/kg IV ketamine.
- haloperidol (Type: EXPERIMENTAL): To do procedural sedation and analgesia in this group, the patients will receive 2 intravenous injections. One will be 0.05 cc/kg of distilled water and the other 5 mg of haloperidol (in 2 cc syringes), 5 minutes before receiving a sedative dose of 1 mg/kg IV ketamine.

Based on this trial design, predict the completion outcome and termination type (if applicable).
