Ketamine and intraocular pressure in children
Anesthesia and Analgesia
|November 1, 1976
Summary
Ketamine does not increase intraocular pressure (IOP) in healthy pediatric patients. This study found no significant IOP rise with ketamine, suggesting its safety for ophthalmic procedures.
Area of Science:
- Anesthesiology
- Ophthalmology
- Pediatric Medicine
Background:
- Intraocular pressure (IOP) is a critical factor in ophthalmic procedures.
- Ketamine is an anesthetic agent with potential effects on IOP that require investigation in pediatric populations.
Purpose of the Study:
- To evaluate the effect of ketamine administration on intraocular pressure in pediatric patients.
- To determine the safety of ketamine for ophthalmic procedures in children.
Main Methods:
- Ten pediatric patients underwent IOP measurements before and after intramuscular ketamine (8 mg/kg).
- Further IOP assessments were conducted after intravenous ketamine (1 mg/kg) and other anesthetic interventions (d-tubocurarine, endotracheal intubation, N2O).
Main Results:
- A statistically significant decrease in IOP was observed after ketamine administration (p < 0.001).
- The authors attributed the IOP reduction to improved patient relaxation rather than ketamine itself.
- Endotracheal intubation was the only intervention that caused a significant IOP increase (6.7 torr).
Conclusions:
- Ketamine does not appear to elevate intraocular pressure in healthy pediatric patients.
- Ketamine is a viable anesthetic option for pediatric ophthalmic procedures.
