[Oral premedication in ambulatory surgical otorhinolaryngology in children]
Insights
Dormicum (midazolam) effectively premedicates children for ambulatory surgery without impacting cardiovascular function. Standard premedication, however, increases hemodynamic activity, particularly in older children.
Area of Science:
- Pediatric Anesthesiology
- Cardiovascular Physiology
- Pharmacology
Context:
- Ambulatory surgery in children requires effective premedication.
- Assessing cardiovascular response to premedication is crucial.
- Age-based grouping (4-7 and 8-14 years) was used.
Purpose:
- To compare the cardiovascular effects of Dormicum versus standard premedication in pediatric patients.
- To evaluate the efficacy of Dormicum (0.5 mg/kg) in children undergoing otorhinolaryngology procedures.
Summary:
- Standard premedication activated central hemodynamics and enhanced left ventricular performance, especially in older children.
- Dormicum (midazolam) at 0.5 mg/kg did not significantly alter central hemodynamics or left ventricular performance.
- Dormicum induced moderate sympathetic activation, proving effective across all age groups.
Impact:
- Dormicum is a safe and effective premedication option for pediatric ambulatory surgery.
- Findings support the use of Dormicum in pediatric otorhinolaryngology settings.
- Provides insights into cardiovascular responses to different premedication strategies in children.
Abstract:
34 children selected into two groups due to age (patients from 4 to 7 year old were included in the 1st group, the 2nd group consisted of children, aged from 8 years to 14 years, were premedicated with dormicum, and in other 37 patients standard premedication was applied. The state of cardiovascular system was estimated by means of indices of central hemodynamics and heart rate monitoring data. Every patient was examined both before and 30 minutes after premedication. While standard premedication activates central hemodynamics, increases, especially in older children, left ventricular performance, premedication with dormicum influence neither indices of central hemodynamics nor left ventricular performance, and causes moderate sympatical activation by dormicum in dose of 0.5 mg/kg, appearing to be effective in children of any age and can be used in ambulatory surgical otorhinolaryngology in children.
