Insights
Isoflurane led to faster recovery but more laryngeal spasms in pediatric anesthesia compared to halothane. Halothane is recommended for induction due to fewer complications in children.
Area of Science:
- Pediatric Anesthesiology
- Inhalational Anesthesia
- Pharmacological Comparison
Background:
- Halothane and isoflurane are common inhalational anesthetic agents used in pediatric care.
- Understanding their comparative clinical profiles is crucial for optimizing anesthetic management in children.
Purpose of the Study:
- To compare the clinical characteristics and complications of halothane versus isoflurane during induction, maintenance, and recovery in pediatric inhalational anesthesia.
Main Methods:
- A comparative study involving 66 children (1 month to 13 years) undergoing short surgeries.
- Patients were divided into two groups: isoflurane (n=33) and halothane (n=33).
- Key parameters included duration of unconsciousness, intubation and recovery times, hemodynamics, and complication incidence.
Main Results:
- Isoflurane resulted in shorter unconsciousness duration but longer intubation times compared to halothane.
- Higher complication rates, primarily laryngeal spasm, were observed with isoflurane during induction.
- While hemodynamics were similar, isoflurane showed lower diastolic pressure during maintenance; recovery was faster and more predictable with isoflurane.
Conclusions:
- Isoflurane is less suitable for pediatric anesthesia induction due to a higher incidence of complications, particularly laryngeal spasm.
- Halothane demonstrates a more favorable safety profile for induction in this pediatric population.
- Despite faster recovery with isoflurane, the increased risk of induction complications favors halothane for initial anesthetic administration.
Objectives:
Comparative study of clinical characteristics and complications during induction, maintenance, and recovery in pediatric inhalational anesthesia between two commonly used fluoride agents (halothane and isoflurane).
Material And Methods:
We studied 66 children aged 1 month to 13 years undergoing general anesthesia for short lasting surgery who were divided into two groups of 33 patients each one: Isoflurane group and halothane group. Induction and maintenance anesthesia was performed with the corresponding inhalant agent. Parameters measured were duration of unconsciousness, time elapsed for intubation and recovery, heart rate, arterial blood pressure, and incidence of complications.
Results:
Children anesthetized with isoflurane showed a shorter period of unconsciousness (1.55 +/- 0.11 min) than those anesthetized with halothane (1.91 +/- 0.12 min); whereas that the time required for intubation was significantly more prolonged (8.94 +/- 0.51 and 6.57 +/- 0.32 min, respectively). The incidence of complications was higher in the isoflurane group, mainly expressed as laryngeal spasm during the induction period. Both groups of patients showed a similar hemodynamic behaviour, although diastolic arterial pressure during maintenance anesthesia was significantly lower with isoflurane. Anesthesia recovery was faster and more predictable with isoflurane than with halothane.
Conclusions:
Anesthetic agent isoflurane is less appropriate than halothane for induction in pediatric anesthesia due to a high incidence of complications, specially laryngeal spasm.
