Objective To explore the effect of chloral hydrate on sleep Electroencephalogram (EEG) in children. Methods A total of 250 children under the age of 5 underwent EEG examination in West China Second University Hospital from Nov.8, 2019 to Sep.1,2021 were enrolled and divided into medication group or non-medication group according to whether they took chloral hydrate before the examination. Among them, 167 patients, the average age of whom was (30.78±17.43) months, were in the medication group, with a male to female ratio of 113:54. 83 cases were in the unmedicated group, the ratio of male to female was 60:23, and the average age was (33.12±17.10) months. There were no statistical difference in age and gender between the two groups. Quantitative EEG method was used to compare and analyze the percentages of the power of various EEG waveforms in the two groups. Results The proportion of EEG beta waves in the medication group was (2.76±4.03)%, and the proportion of EEG beta waves in the non-medication group was (1.59±1.21)%. There was a significant difference between the two groups. The proportion of sleep EEG beta waves in the medication group is higher. Conclusions Chloral hydrate may cause the increase of β fast waves in sleep EEG, which may affect the interpretation of EEG and the diagnosis of diseases.
ObjectiveTo investigate the effect of acoustic earplugs combined with sedative drugs on improving the success rate of MRI examinations in children with epilepsy, and to provide an effective clinical evidence for MRI examination in children with epilepsy for the future.MethodsSeventy-four children with epilepsy who came to the Second Affiliated Hospital of Guangzhou Medical University, between July 2016 and February 2018 were included in this research. To test the effectiveness of acoustic earplugs on children with epilepsy in improving MRI success rates, participants were divided into two groups randomly. The control group only took the drug and withont using the acoustic earplugs. The observation group used both the drug and acoustic earplugs. The comparing the success rate of MRI examination between the two groups.ResultsThe observed group (with the acoustic earplugs) showed a success rate of 97.29% (36/37), the control group (without the acoustic earplugs) showed a success rate of 18.91% (7/37). The success rate of the observed group was higher than the control group (P<0.05) significantly.ConclusionsThe use of acoustic earplugs combined with sedative drugs is effective in improving the success rate of MRI examination in children with epilepsy and can be widely used in clinical practice.
