疫情防控期间术后面罩吸氧患儿佩戴口罩的安全性研究

A Study on the Safety of Wearing Masks in Children with Postoperative Mask Oxygen Inhalation During Epidemic Prevention and Control

目的探讨新型冠状病毒感染疫情防控期间术后面罩吸氧患儿佩戴口罩的安全性。方法选择2021年4—8月于浙江省台州医院进行手术治疗的60例患儿为研究对象,采用随机数字表法分为试验组和对照组,每组30例。试验组术后拔除气管插管并立即佩戴一次性医用儿童口罩,对照组患儿不佩戴口罩。患儿转移至麻醉后恢复室并使用普通吸氧面罩进行氧疗,比较两组0、5、10、15、30、45 min时心率(HR)、氧饱和度(SPO_(2))、呼气末二氧化碳分压(ETCO_(2))和呼吸频率(RR)水平。结果两组HR、SPO_(2)的时间效应、组别效应和时间×组别交互效应比较,差异均无统计学意义(P>0.05)。两组RR和ETCO_(2)水平比较,存在时间效应,差异有统计学意义(P<0.05),但组别效应和时间×组别交互效应比较,差异均无统计学意义(P>0.05)。结论患儿术后氧气面罩吸氧期间佩戴医用口罩不会引起呼吸参数的不良变化。

Objective To explore the safety of wearing masks for children with oxygen inhalation after operation during the prevention and control of novel coronavirus epidemic situation.Methods With the selection of sixty pediatric patients underwent surgical treatment at Taizhou Hospital in Zhejiang Province from April to August 2021 as the research subjects,they were randomly divided into the experimental group and the control group,by using the random number table method,with 30 cases in each group.After removing the tracheal cannula,the experimental group immediately wore a disposable medical children's mask,while the control group did not wear a mask.With the transfer of the child to the post anesthesia recovery room,and the use of a regular oxygen mask for oxygen therapy,heart rate(HR),oxygen saturation value(SPO_(2)),end end-tidal carbon dioxide(ETCO_(2)),and respiratory rate(RR)levels were compared between two groups at 0,5,10,15,30,and 45 minutes.Results There were no statistically significant differences in the time and group effect of HR and SPO_(2),and time×group interaction effect between the two groups(P>0.05).The comparison of RR and ETCO_(2) levels between the two groups showed a time effect,and the difference was statistically significant(P<0.05),but there were no statistically significant differences in group effect and time×group interaction effect(P>0.05).Conclusion During postoperative oxygen mask inhalation,wearing a medical mask in children does not cause adverse changes in respiratory parameters.
