ABSTRACT

Objective:To investigate the clinical effect of early bronchoalveolar lavage on patients with aspiration pneumonia.Methods:A retrospective study was conducted on 55 patients with aspiration pneumonia who met inclusion criteria but not exclusion criteria in the Intensive Care Department of our hospital from January 2020 to April 2021. The patients were divided into the control group (32 cases) and the bronchoscopic lavage group (23 cases) according to whether they received bronchoscopic lavage within 24 h after aspiration. Basic information (sex, age, body mass index, chest X-ray score, oxidation index, temperature, heart rate, respiratory rate, white blood cells, PCT, IL-6, CPR and APACHE Ⅱ score), etiology changes at the early stage (≤ 3 d) and later stage (4-7 d after admission), and changes in prognostic indexes (mechanical ventilation time, length of ICU stay, length of stay and mortality) were compared between the two groups. The clinical efficacy of early endoscopy lavage for aspiration pneumonia was evaluated.Results:The positive rate of early etiological culture was 85.2%, the bacterial positive rate was 72.9% and the fungal positive rate was 14.6%. Pseudomonas aeruginosa accounted for 20.8%, Klebsiella pneumoniae accounted for 14.6%, Staphylococcus aureus and Streptococcus accounted for 12.5%, and there was no significant difference in the distribution between the bronchoscopic lavage group and the control group (all P>0.05). The positive rate of late etiological culture was 88.6%, the bacterial positive rate was 85.7% and the fungal positive rate was 2.9%. The positive rate of late bacterial culture was significantly decreased in the bronchoscopic lavage group ( P < 0.05), and the other results were not significantly different from the control group (all P>0.05). After early bronchoscopic lavage, the duration of mechanical ventilation, length of ICU stay and length of stay were significantly shortened, and the fifth day CPIS score was significantly decreased (all P< 0.05). Conclusions:Early endotracheal lavage can reduce mechanical ventilation time, length of ICU stay and length of stay of aspiration pneumonia, and reduce the positive rate of bacterial culture in the lung at the later stage, which needs to be further verified by a large randomized controlled study.

ABSTRACT

Objective:To explore the value of ultrasonic measurement of optic nerve sheath diameter (ONSD) in predicting the risk of death in patients with severe brain injury.Methods:This was a prospective observational study based on 84 postoperative patients with severe brain injury from January 2020 to September 2020 in our department. The patients were divided into two groups: the survival group and the deceased group. The clinical features between the two groups were compared. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of ONSD, neuron-specific enolase (NSE) and the combination of the two in predicting death in patients with severe brain injury. Binary logistic regression was used to analyze the independent risk factors for death. A prediction model for the risk of death was constructed.Results:There were 61 cases (72.6%) in the survival group and 23 cases (27.4%) in the deceased group. There were significant differences in age, Glasgow coma score (GCS), ONSD and NSE at 12 h after surgery between the two groups. According to the ROC curve, the optimal cutoff levels of ONSD and NSE for predicting death were 5.5 mm and 21.75 ng/mL, respectively. When the two indicators were combined, the area under the curve was 0.897 ( P<0.01). At this threshold, the sensitivity and specificity were 100% and 70.5%, respectively. ONSD ( OR=9.713; 95% CI: 1.192-79.147) and GCS scores ( OR=0.492; 95% CI: 0.318-0.763) at 12 h after surgery were independent risk factors for death in patients with severe brain injury (both P<0.05). Conclusions:Early postoperative ONSD is an independent risk factor for death in patients with severe brain injury. The combination of ONSD and NSE has the best predictive effect.
