Acoustic environment is an important part of the overall environment of a hospital. Acoustic environmental pollution will have varying degrees of impact on human physiology and psychology. Acoustic environmental pollution in outpatient clinics has become a major concern for visitors and medical staff. Exploring the causes of outpatient acoustic environment pollution and adopting active countermeasures are effective methods to control outpatient acoustic environment pollution. This article will review the current situation of acoustic environmental pollution in outpatient clinics and the impact of acoustic environmental pollution on medical staff and visitors, and analyze the common causes of outpatient acoustic environmental pollution based on actual conditions, and propose corresponding solutions for the corresponding causes. It aims to provide a reference for clinically effective control of acoustic environmental pollution in outpatient clinics.
ObjectiveTo evaluate the effect of disinfection measures in the isolation ward of ICU in severe patients infected with the Omilkerong variant of the new coronavirus, and to optimize the infection control measures. MethodsReferring to the patient's epidemiological and nucleic acid sample data, nucleic acid sampling was performed on the isolated ward environment by surface sampling method, and the nucleic acid Ct value of virus was detected by parallel fluorescence PCR method. The aerosol was collected by a wet-wall cyclone sampler, and the nucleic acid Ct value of the virus was detected by parallel fluorescence PCR. ResultsBefore daily disinfection, SARS-CoV-2 positive samples were found on the surface of the patient's ward and air sampling after the tracheoscopic tracheostomy. No positive samples of SARS-CoV-2 were found on the surface of articles and air in the patient's ward after daily disinfection. ConclusionThe daily disinfection measures of the hospital can achieve the effect of SARS-CoV-2 disinfection, which suggests that the surface of the articles in the ward after invasive operations such as tracheostomy and tracheoscopy, especially within 2 meters of the tracheostomy and the tracheostomy, is the key part of disinfection, which needs to be paid attention to.
