Abstract:

Objective To design and investigate the application of a sealed negative pressure stool collector for children with diarrhea. Methods Sealed negative pressure excrement collector is composed of negative pressure ball，sample tube，limiter，casing sheath and so on. 159 children with diarrhea admitted to the emergency department of our hospital（a tertiary A children’s hospital in Hangzhou） from January to December 2021 were convenience sampled as the research subjects and divided into an experimental group with 88 cases and a control group with 71 cases by random number table method. A sealed negative pressure stool collector was used to collect stool samples in the experimental group，and an ordinary anal swab was used in the control group. The success rate of fecal specimen collection，fecal spatter rate，intestinal mucosal injury rate，fecal specimen collection time，and satisfaction with the sampler were compared between the 2 groups. Results Compared with the control group，the experimental group was significantly higher in the success rate of fecal specimen collection and satisfaction with the sampler（all P<0.05）;the fecal spatter rate and intestinal mucosal injury rate in the experimental group were significantly lower than those in the control group（all P<0.05）;there was no significant difference in the fecal specimen collection time（P=0.069）. Conclusion The use of the sealed negative pressure stool collector to collect stool specimens for children with diarrhea can improve the success rate of fecal specimen collection，reduce fecal spatter rate and intestinal mucosal injury rate，and the staff for the sampler has a high degree of satisfaction.
