Effect of White Noise Combined with Chloral Hydrate Sedation on Improving the Success Rate of MRI Examination in Neonatal

<i>Objective: </i>Observe the sedative effect of white noise combined with hydrolytic aldarin in the newborn MRI examination. <i>Methods:</i> Selected 70 newborns of MRI inspections received by Zhuhai City People's Hospital from November 2021 to November 2023, using random digital tables to divide them into the observation group and control group, each group of 35 cases. The control group used 10% chloral hydrate solution to perform retention enema 30 minutes before MRI examination according to the dosing standard of 0.5 ml/kg. The observation group used laxative drugs for retention enema 15 minutes before chloral hydrate administration, and white noise intervention was given for sleep deprivation on the basis of the control group. Compare the two sets of MRI to check successful power, as well as Brussels sedation score and vital signs at different time points before and after intervention. Observe the occurrence of adverse reactions in the two groups. <i>Results:</i> Brussels sedation score in both groups showed a downward trend with the progress of time, and the change range in the observation group was greater <i>(P</i><0.05). The blood oxygen saturation in both groups showed an upward trend with the progress of intervention time, while the systolic blood pressure, heart rate and respiratory rate showed a downward trend (<I>P</I><0.05). The heart rate and respiratory rate in the observation group decreased significantly compared with those in the control group (<I>P</I><0.05). There were no adverse reactions such as bradycardia, hypotension and decreased oxygen saturation in both groups. <i>Conclusion:</i> White noise combined with chloral hydrate has obvious sedative and analgesic effects in neonatal MRI examination, which is safe and worth popularizing.
