Effect of budesonide aerosol inhalation on postoperative complications and foreign body sensation in the throat of goiter resection patients

Purpose: To study the effect of budesonide aerosol inhalation on postoperative complications and foreign-body sensation in the throat of patients who underwent goiter resection.Methods: One hundred and twenty patients who underwent goiter resection at The Affiliated Hospital of Putian University (Fujian, China) from January 2019 to January 2020 were included in the study, and then equally and randomly assigned to groups A and B. During the perioperative period, group A patients were given budesonide aerosol inhalation, while group B patients received aerosol inhalation of equivalent volume of normal salineectively. Postoperative complication rate (CR), complication pain scores, scores on mucosal response in the throat, and scores on foreign body sensation in the throat were determined for both groups.Results: Postoperative complications in patients were hoarseness, sore throat and cough. Group A had significantly lower postoperative CR, lower complication pain scores, lower scores on mucosal response in the throat, and lower scores on foreign body sensation in the throat, when compared to group B (p < 0.001).Conclusion: Budesonide aerosol inhalation in patients who underwent goiter resection is effective in relieving throat injury from general anesthesia, minimizing likelihood of postoperative complications, and easing foreign-body sensation in the throat. Thus, this strategy may be suitable for the management of postoperative complications.

Modelling aerosol-based exposure to SARS-CoV-2 by an agent based Monte Carlo method: Risk estimates in a shop and bar

Present day risk assessment on the spreading of airborne viruses is often based on the classical Wells-Riley model assuming immediate mixing of the aerosol into the studied environment. Here, we improve on this approach and the underlying assumptions by modeling the space-time dependency of the aerosol concentration via a transport equation with a dynamic source term introduced by the infected individual(s). In the present agent-based methodology, we study the viral aerosol inhalation exposure risk in two scenarios including a low/high risk scenario of a “supermarket”/“bar”. The model takes into account typical behavioral patterns for determining the rules of motion for the agents. We solve a diffusion model for aerosol concentration in the prescribed environments in order to account for local exposure to aerosol inhalation. We assess the infection risk using the Wells-Riley model formula using a space-time dependent aerosol concentration. The results are compared against the classical Wells-Riley model. The results indicate features that explain individual cases of high risk with repeated sampling of a heterogeneous environment occupied by non-equilibrium concentration clouds. An example is the relative frequency of cases that might be called superspreading events depending on the model parameters. A simple interpretation is that averages of infection risk are often misleading. They also point out and explain the qualitative and quantitative difference between the two cases—shopping is typically safer for a single individual person.

Deep Learning Algorithms-Based CT Images in Glucocorticoid Therapy in Asthma Children with Small Airway Obstruction

CT image information data under deep learning algorithms was adopted to evaluate small airway function and analyze the clinical efficacy of different glucocorticoid administration ways in asthmatic children with small airway obstruction. The Res-NET in the deep learning algorithm was used to perform feature extraction, summary classification, and other reconstruction of CT images. A deep learning network model Mask-R-CNN was constructed to enhance the ability of image reconstruction. A total of 118 children hospitalized with acute exacerbation of asthma in the hospital were recruited. After acute exacerbation treatment, 96 children with asthma were screened out for small airway obstruction, which were divided into glucocorticoid aerosol inhalation group (group A, 32 cases), glucocorticoid combined with bronchodilator aerosol inhalation group (group B, 32 cases), and oral hormone therapy group (group C, 32 cases). Asthmatic children with small airway obstruction were screened after acute exacerbation treatment and were rolled into glucocorticoid aerosol inhalation group (group A), glucocorticoid combined with bronchodilators aerosol inhalation group (group B), and oral hormone therapy group (group C). Lung function indicators (maximal mid-expiratory flow (MMEF75 and 25), 50% forced expiratory flow (FEF50), and 75% forced expiratory flow (FEF75)), FeNO level, and airway inflammation indicators (IL-6, IL-35, and eosinophilic (EOS)) were compared before and one month after treatment. The ratio of airway wall thickness to outer diameter (T/D) and the percentage of airway wall area to total airway area (WA%) were measured by e-Health high-resolution CT (HRCT). The constructed network model was used to measure the patient's coronary artery plaque and blood vessel volume, and the image was reconstructed on the Res-Net network. It was found that the MSE value of the Res-Net network was the lowest, and the efficiency was very high during the training process. T/D and WA (%) of asthmatic children with small airway obstruction after treatment were significantly lower than those before treatment ( P < 0.01 ). After treatment, MMEF75/25 and FEF75 were significantly higher than those before treatment ( P < 0.05 ). Lung function-related indicator FEF50 was significantly higher than that before treatment ( P < 0.01 ). FeNO level after treatment was remarkably lower than that before treatment ( P < 0.01 ). In addition, lung function-related indicators, airway inflammation indicators, and FeNO level improved the most in group C, followed by group B, and those improvements in group A were the least obvious, with great differences among groups ( P < 0.05 ). In summary, the Res-Net model proposed was of certain feasibility and effectiveness for CT image segmentation and can effectively improve the clinical evaluation of patient CT image information. Glucocorticoids could improve small airway function and airway inflammation in asthmatic children with small airway obstruction, and oral corticosteroids were more effective than aerosol inhalation therapy.

Effect of Aerosol Inhalation of Budesonide Suspension on Clinical Efficacy, Remission Time of Asthma and Disappearance Time of Rales in Children with Mycoplasma Pneumoniae Pneumonia

To investigate the effect of aerosol inhalation of budesonide suspension on clinical efficacy, remission time of asthma and disappearance time of rales in children with mycoplasma pneumoniae pneumonia. Methods: 100 cases of mycoplasma pneumoniae pneumonia in our hospital from February 2019 to February 2021 were randomly divided into study group (n = 50) and control group (n = 50). The control group was given azithromycin intravenous drip followed by oral treatment, and the study group was given aerosol inhalation of budesonide suspension on the basis of the control group. Results: Compared with the control group, disappearance time of rales in the study group, remission time of cough, remission time of asthma and time of hospitalization in the study group were relatively short (P<0.05), and the efficacy in the study group was relatively high (P<0.05). There was no significant difference in the incidence of nausea, vomiting, abdominal pain, diarrhea and hoarseness between the two groups (P>0.05). The improvement of FVCS FEV1 and PEF and other indexes was relatively high in the study group by comparing with the control group (P<0.05). Conclusion: Aerosol inhalation of budesonide suspension in children with mycoplasma pneumoniae pneumonia can effectively enhance the therapeutic effect, promote the improvement of lung function, and reduce the disappearance time of rales and remission time of asthma, so it can be popularized.
