Summary
Closed-system low-flow anesthesia using enflurane or halothane is practical and economical for pediatric patients. Isoflurane, however, showed complications, suggesting it is less suitable for this technique in children.
Area of Science:
- Anesthesiology
- Pediatric Anesthesia
Background:
- Closed-system anesthesia offers potential economic and environmental benefits.
- Low-flow techniques aim to reduce anesthetic agent consumption.
Purpose of the Study:
- To evaluate the efficacy and safety of a closed-system low-flow anesthetic technique in pediatric patients.
- To compare enflurane, halothane, and isoflurane for this technique in children.
Main Methods:
- Three groups of ten pediatric patients each received anesthesia via a closed-system low-flow technique.
- Anesthetics used were enflurane, halothane, or isoflurane, administered through priming and subsequent injections.
- Maintenance involved "square root of time" sequence injections.
Main Results:
- Average anesthetic volumes used were 3.7 ml (enflurane), 2.3 ml (halothane), and 3.0 ml (isoflurane).
- Anesthetic volumes and injection frequency were higher than theoretically predicted.
- Complications were noted with isoflurane, unlike enflurane and halothane.
Conclusions:
- Closed-system low-flow anesthesia is a viable, cost-effective, and environmentally friendly option for pediatric anesthesia.
- Enflurane and halothane appear more satisfactory than isoflurane for this technique in infants and children.
