# Analysis of the use and advantages of depth of anaesthesia monitoring in children undergoing tonsillar adenoid surgery

## TL;DR

This study shows that using depth of anesthesia monitoring with dexmedetomidine in children during tonsillar adenoid surgery improves recovery and reduces stress.

## Contribution

The study demonstrates the benefits of depth of anesthesia monitoring with dexmedetomidine in pediatric tonsillar adenoid surgery.

## Key findings

- Dexmedetomidine reduced heart rate and blood pressure during surgery compared to the control group.
- Children in the observation group had shorter extubation and respiratory recovery times.
- Dexmedetomidine reduced adverse events and stress response in pediatric patients.

## Abstract

To investigate the application and analysis of the advantages of depth of anesthesia monitoring in children undergoing tonsillar adenoid surgery.

Eighty tonsillar adenoid surgery patients were divided into a control group and an observation group. Observation group was given dexmedetomidine. Saline was given to the control group. Hemodynamics, perioperative indicators, stress reaction indicators, and adverse reactions were compared.

At t0, no statistically significant differences were found between the two groups for mean arterial pressure (MAP) (t =0.3789) or heart rater (HR) (t =0.0130). On t1, t2, t3 and t4, the mean arterial pressure (MAP) (tt1=4.5321, tt2=2.5818, tt3=5.0025, tt4=3.2068) and heart rater (HR) (tt1=6.64299, tt2=29.4580, tt3=15.5095, tt4=10.1461) were lower compared to the control group (P<0.05). Extubation time (t=49.9687) and respiratory recovery time (t=16.4542) of children in the observation group were shorter than those of the control group (t=20.1926), a statistical difference was found between the groups (P<0.05). Observation group adverse events were 0.44% lower than control group (x2=5.1647, P<0.05).

During tonsillar adenoid surgery, dexmedetomidine hydrochloride was used to anesthetize children. The dosage of anesthetic drugs was adjusted according to the depth of anesthesia monitored. Despite its small effect on hemodynamic indexes, it delayed extubation, reduced organism stress, and facilitated respiratory management.
