ObjectiveTo explore the influence of general anesthesia with laryngeal mask and preoperative inhalation of budesonide aerosol on the incidence of respiratory adverse events during pediatric anesthesia recovery. MethodsA total of 100 child patients scheduled to undergoing inguinal hernia repair between December 2012 and February 2014 were randomly divided into two groups (group A and B) with 50 in each. All the patients underwent general anesthesia with laryngeal mask, while patients in group B inhaled budesonide aerosol before anesthesia. Then, we observed the incidence of adverse events in both groups, including laryngospasm, respiratory tract infection, and pulmonary complications. ResultsCompared with group A, patients in group B had a lower incidence of adverse events (P<0.05). ConclusionPreoperative application of budesonide aerosol inhalation can significantly reduce adverse events in the process of anesthesia recovery in children.
ObjectiveTo observe the clinical efficacy of triple aerosol inhalation of pulmicort respules,ipratropine and ventolin in treatment of severe acute asthma exacerbations in adults. Methods46 cases of severe asthmatic patients with acute exacerbations admitted between May 2011 and May 2013 were recruited in the study.They were randomly divided into a treatment group and a control group,23 cases in each group.The control group received aminophylline and methylprednisolone intravenously,while the treatment group received triple aerosol inhalation of pulmicort respules,ipratropine and ventolin on the basic treatment of the control group.The clinical efficacy,the score of asthma symptom of the day and night,the time of disappearance of symptoms and wheezing sound,the glucocorticoid dosage and the incidence of adverse reactions of each group were compared. ResultsComparison of clinical efficacy of two groups drew significant differences (P<0.05) after 7 days.The score of asthma symptom of the day and night in the treatment group was lower than that of the control group (P<0.05).Except cough,the duration of wheezing,breathlessness,chest distress and extinction time of wheezing sound in the treatment group were shorter than those in the control group (P<0.05).The triple inhalation therapy can reduce the dosage and shorten the period of intravenous glucocorticoid treatment with slight adverse reactions (P<0.05). ConclusionIn the treatment of severe asthmatic patients with acute exacerbations,the clinical efficacy of triple aerosol inhalation of pulmicort respules,ipratropine and ventolin on the base of intravenous treatment is satisfactory with rapid onset,which can also reduce the glucocorticoid dosage and the incidence of adverse reactions.So the combination therapy is worthy of clinical use.
Objective To evaluate the efficacy and safety of inhaled amphotericin B ( AmB) in prophylaxis of invasive pulmonary aspergillosis ( IPA) in both animal studies and clinical researches. Methods MEDLINE, ISI, EMBASE and Wanfang Periodical Databases were searched until march 2011 for case-control study on the efficacy and safety of inhaled AmB in prophylaxis of IPA. The articles were evaluated according to inclusion criteria. Poor-quality studies were excluded, and RevMan 4. 22 sofeware was applied for investigating the heterogeneity among individual studies and calculating the pooled odds ratio ( OR) and 95% confidence interval ( CI) . Results Five animal studies with a total of 626 animals were included. The overall survival rate of the immunosuppressed animals with pulmonary aspergillosis treated with nebulized AmB was increased ( 38.3% vs. 9.7% , OR=13.93, 95% CI 7.46 ～26.01, Plt;0. 000 01) . Six clinical trials including 1354 patients were considered. Our meta-analysis showed that inhaled AmB could significantly reduce the incidence rate of IPA ( 2.6% vs. 9.2% , OR=0.27, 95% CI 0.16 ～0.46, P lt;0. 000 01) , but had no definite benefit on mortality. Four studies evaluated the potential side effects of nebulized AmB and showed that there were no significant adverse events. Conclusions Empirical inhaled AmB is associated with a lower rate of IPA but no significant
Objective To evaluate the effects of midazolam intravenous drip combined with lidocaine via nebulization on patients during mechanical ventilation in intensive care unit ( ICU) . Methods 60 thoracic patients required postoperative mechanical ventilation in ICUwere randomized into 2 groups. The patients in therapeutic group received lidocaine 1 mg/kg via nebulization and midazolam intravenous drip 0. 1 mg·kg- 1·h- 1 . The patients in control group received 0. 9% NaCl 1 mg/kg via nebulization andmidazolam0. 1 mg·kg- 1 ·h- 1 . According to the scale of Ramsay, the additional midazolam and fentanyl were injected to maintain sedation and inhibit cough in both groups. During ventilation, calm score, the number and the severity of cough, the mean arterial pressure ( MAP) , heart rate ( HR) , and the consumption of midazolam and fentanyl were record. Results The number and severity of cough, the scale of MAP and HR in the therapeutic group were all significant lower than those in the control group ( P lt; 0. 05) . Theconsumption of midazolam and fentanyl in the therapeutic group were also significantly lower than that in the control group ( P lt; 0. 05) .Conclusion Midazolam intravenous drip combined with lidocaine via nebulization can reduce the side effects and requirement of sedative and opioids drug in ICU patients undergoing mechanical ventilation.
Objective To evaluate therapeutic efficacy and safety of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) inhalation in patients with recurrent pulmonarv alveolar proteinosis (PAP). Methods Three cases of recurrent PAP were treated by GM-CSF inhalation after whole lung lavage. The clinical data of the pulmonary function and SpO 2, the clinical symptoms and pulmonary lesions were compared before and after treatment. Results The pulmonary function and manifestations were improved obviously after GM-CSF inhalation. Also the ground-glass opacity was improved in high-resolution CT. The pulmonary function and SpO 2 increased obviously after received GM-CSF inhalation. There were no any adverse reactions in 3 cases. Conclusion GM-CSF inhalation therapy is effective and safe in recurrent PAP, but the long-term effect remains to be seen.
ObjectiveTo evaluate the clinical manifestation, radiological, pathological features and treatment of organizing pneumonia (OP) induced by aerosolized recombinant super compound interferon (rSIFN-co). MethodsClinical features and related laboratory examinations of a patient with OP developing after initiation of rSIFN-co for treatment of lung adenocarcinoma were analyzed, and the relevant literature was reviewed. ResultsA 48-year-old man developed cough, fevers, shortness of breath and weight loss, shortly half a month after initiation of therapy with rSIFN-co for lung adenocarcinoma. Chest high resolution computerized tomography (HRCT) showed multiple lung infection diseases. However, the anti-infection treatment was invalid. Lung tissue biopsy by bronchofibroscope was consistent with OP. After discontinuation of rSIFN-co and receiving pulse corticosteroid therapy followed by oral methylprednisolone, the pneumonic symptoms and chest manifestations markedly improved. After eight-month follow-up, the patient's condition was stable. The relative literature screening from Pubmed and Wanfangdata was implemented, but there was no report about OP caused by aerosolized rSIFN-co for lung adenocarcinoma. ConclusionThis report suggests that treatment with aerosolized rSIFN-co for lung adenocarcinoma may induce OP, a rare complication, and clinicians should have vigilance on it.
Objective To compare the application effects of two kinds of oxygen and nebulizer inhalation devices applied to patients undergoing partial hepatectomy, with a view to providing reference for clinical selection oxygen and nebulizer inhalation modality. Methods A prospective case-control study was used to select 228 patients who required oxygen inhalation and nebulization after hepatectomy under general anesthesia in the Department of Liver Surgery of West China Hospital of Sichuan University from January to December 2022 as study subjects, and were randomly divided into two groups: grouping group (n=77) and integrating group (n=151). The traditional oxygen inhalation device and atomization device (grouping oxygen inhalation atomization device) commonly used in clinic were used in the grouping group, and the humidifying bottle and humidifying water were replaced every 24 hours. The integrating group adopts a new device (integrated oxygen atomization inhalation device) which integrates oxygen inhalation and atomization functions. The integrating group was divided into integrating group 1 (n=77) and integrating group 2 (n=74) according to the different time of changing the humidifying bottle and humidifying water. The time for replacing the humidifying bottle and humidifying water in the integrating 1 was the same as that in the grouping group. The time for replacing the humidifying bottle and humidifying water in the integrating group 2 was 48 h after used, and replace again it after 72 hours of used. Samples from different parts of the grouping group and the integrating group 1 were collected at 24 h, 48 h, 72 h, 96 h and 120 h after oxygen inhalation, respectively, for colony culture. In the integrating group 2, samples were taken for colony culture when the device was changed twice (48 h and 120 h). At the same time, the nurses’ fogging operation time and the fogging noise of the two groups were measured. The self-made patients’ satisfaction questionnaire and nurses’ questionnaire were used to investigate the satisfaction of two groups of patients and 30 medical staff respectively. Results There were no statistically significant difference in the number of bacterial colonies between the grouping group and the integrating group 1 at different time periods and between the two groups at the same time (P＞0.05). In terms of atomization performance, atomization noise in the integrating group was lower than that of the grouping group (P＜0.05), and the atomization preparation and disposal time in the integrating group were shorter than that of the grouping group (P＜0.05). The patients and nurses were more satisfied with the integrating group (P＜0.05). Conclusions There is no difference in pollution risk between the integrated oxygen atomization bottle and the grouped oxygen atomization bottle. The atomization performance and humidification performance of the integrated oxygen atomization bottle are better than that of the grouped oxygen atomization bottle. The noise generated during operation is small, the comfort of patients is high, and the operation time of nurses can be shortened and the work efficiency can be improved, which has high clinical application value.
ObjectiveTo analyze the effect of different nebulization methods in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) requiring non-invasive ventilators (NIV). MethodsOne hundred and two patients with AECOPD were selected according to the standard, and randomly divided into a control group, a trial group I, and a trial group II according to the random number table. The patients in the control group received NIV intermittent oxygen-driven nebulization; the patients in the trial group I received NIV simultaneous oxygen-driven nebulization; and the patients in the trial group II received NIV simultaneous air-driven nebulization. The dynamic fluctuations of transcutaneous partial pressure of carbon dioxide (PtCO2), arterial blood gas indexes (PaCO2, PaO2, pH), vital signs and pulse oxygen saturation (SpO2) fluctuations were compared. ResultsPtCO2 at 15min of nebulization in the trial group II were lower than the other groups (P<0.05). PtCO2 at 15min of nebulization was higher than the other time points in the control group (P<0.05); there was no statistical difference of PtCO2 at different time points in the trial group I (P>0.05); PtCO2 gradually decreased with time in the trial group II (P<0.05). The difference before and after nebulization of PtCO2 (dPtCO2) was larger in trial group II than the other groups (P<0.05). PtCO2 at 0min and 5min after the end of nebulization in trial group II were lower than the other groups (P<0.05); there were no statistical differences of PtCO2 at 10min and 15min after the end of nebulization among three groups (P>0.05). There were statistical differences of the PtCO2 at each time point in the control group except for the PtCO2 at 10 min and 15min after the end of nebulization, all of which decreased with time; PtCO2 at each time points of nebulization decreased with time in the trial group I (P<0.05). PtCO2 only at 5min after the end of nebulization was lower than that at 0min after the end of nebulization in trial group II (P< 0.05), there were no statistical differences in other times (P>0.05). PaCO2, pH at the 4th day of treatment was lower than the pre-treatment in the control group (P<0.01); there were statistical differences of PaCO2 between the pre-treatment and the rest time points in the trial group I and group II (P<0.05). The number of abnormal fluctuations in vital signs and SpO2 during nebulization in three groups was not statistically different (P>0.05). ConclusionsThree groups can achieve good therapeutic effects. NIV intermittent oxygen-driven nebulization can make PtCO2 rise during nebulization; NIV simultaneous oxygen-driven nebulization can make PtCO2 remain stable during nebulization; NIV simultaneous air-driven nebulization can make PtCO2 fall during nebulization.
