Adding ketamine to propofol sedation in children significantly reduced recovery time. Both propofol-only and ketamine plus propofol approaches were equally effective and safe for pediatric deep sedation procedures.
Area of Science:
- Pediatric Anesthesiology
- Procedural Sedation
- Pharmacology
Background:
- Propofol is widely used for pediatric deep sedation.
- Its use as a nonanalgesic agent for procedures is debated.
- Two sedation protocols are employed: propofol-only (P-O) and ketamine plus propofol (K+P).
Purpose of the Study:
- To compare the dosing, efficacy, and safety of P-O versus K+P for deep sedation in children.
- To evaluate the impact of ketamine addition on sedation parameters.
Main Methods:
- Retrospective evaluation of 754 pediatric patients undergoing procedural sedation.
- Patients received either P-O or K+P sedation.
- Data collected included sedation doses, procedure time, and recovery time.
Main Results:
- No significant difference in age or weight between the 372 P-O and 382 K+P patients.
- A combined hypoxia incidence of 16% was observed.
- K+P group had longer procedure times (18.7 vs 15.1 min) but shorter recovery times (17.0 vs 22.2 min) compared to P-O.
- Mean propofol dose was lower in the K+P group (0.28 vs 0.40 mg/kg/min).
Conclusions:
- Both P-O and K+P sedation approaches are well-tolerated and effective in pediatric patients.
- Addition of ketamine to propofol is associated with reduced recovery time.
- Decreased propofol requirement in the K+P group likely explains the shorter recovery.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
