Behavioural changes and children's memories after intravenous, inhalation and rectal induction of anaesthesia
1Department of Anaesthesiology, Oulu University Hospital, Finland.
Insights
Intravenous and rectal anesthesia inductions were found to be less distressing for young children compared to inhalational induction. Postoperative behavioral changes were similar across all anesthesia methods studied.
Area of Science:
- Pediatric Anesthesiology
- Child Psychology
Background:
- Anesthesia induction in children can cause distress and behavioral changes.
- Evaluating parental perception of postoperative behavior is crucial for assessing anesthetic techniques.
Purpose of the Study:
- To compare the effects of intravenous thiopentone, halothane inhalation, and rectal methohexitone on children's postoperative behavior and memories.
- To determine which anesthesia induction method causes the least distress in pediatric patients.
Main Methods:
- Randomized controlled trial involving 92 children aged 2-7 years undergoing day case ENT surgery.
- Children received anesthesia via intravenous thiopentone, halothane inhalation, or rectal methohexitone.
- Parental questionnaires assessed behavioral changes at 1 day, 1 week, and 1 month post-operation.
Main Results:
- No significant differences in problematic postoperative behavioral changes were observed between the three groups (59% IV thiopentone, 50% halothane, 58% rectal methohexitone).
- Children in the halothane inhalation group reported significantly more negative memories of anesthesia induction and hospitalization.
- Fewer negative memories were associated with intravenous and rectal induction methods compared to inhalational induction.
Conclusions:
- Intravenous and rectal anesthesia inductions appear to be less distressing for young children than inhalational induction, based on their reported memories.
- While overall behavioral changes were similar, subjective experiences of distress during anesthesia induction varied significantly by method.
Abstract:
Ninety two-to-seven-year-old children admitted for routine day case ENT operations were randomly allocated to have either intravenous thiopentone (group I), halothane inhalation (group II) or rectal methohexitone (group III) for anaesthesia induction. Using a postoperative questionnaire, the parents evaluated the changes in the child's behaviour one day, one week and one month after the operation. Problematic changes were detected in 17 (59%) children in group I, 14 (50%) in group II and 17 (58%) in group III (NS). Although the children in group II behaved most calmly during the induction they had significantly more negative memories of the induction of anaesthesia (six children in group II vs two in group I and one in group III) and of the hospital in general (17 in group II vs 11 in group I and eight in group III) than children in the other groups. Judging from memories of young children, intravenous and rectal inductions are less distressing to them than inhalational induction.
