Brain injury after cardiopulmonary resuscitation is closely related to the survival rate and prognosis of neurological function of cardiac arrest (CA) patients. Recently, the American Academy of Neurology (AAN) published a practice guideline which had updated the evaluation of different treatments for reducing brain injury following cardiopulmonary resuscitation. In order to master and transmit AAN 2017 practice guideline on reducing brain injury following cardiopulmonary resuscitation, this paper interprets the new AAN clinical practice guideline to assist Chinese clinicians for better studying the guideline.
ObjectiveTo systematically evaluate the efficacy of fiberoptic bronchoscopy for patients with stroke-associated pneumonia (SAP).MethodsAll randomized controlled trials on fiberoptic bronchoscopy in treating SAP were collected from Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, Chinese Biology Medicine database, Wanfang database, and Chongqing VIP database. Two reviewers screened the literature, extracted data, and assessed the methodological quality of included studies. And then meta-analysis was conducted using RevMan 5.3 software.ResultsTwelve studies with 1 107 patients were included. Compared with the routine therapy, the fiberoptic bronchoscopy combined with routine therapy showed a better efficacy [relative risk (RR)=1.26, 95% confidence interval (CI) (1.17, 1.36), P<0.000 01], and indicated a shorter hospital-stay [mean difference (MD)=–4.29 days, 95%CI (–5.06, –3.52) days, P<0.000 01] and lower Clinical Pulmonary Infection Score values [MD=–1.13, 95%CI (–1.77, –0.49), P=0.000 5]. Meanwhile, a downward trend in the level of procalcitonin [standardized mean difference (SMD)=–3.86, 95%CI (–4.22, –3.50), P<0.000 01], tumor necrosis factor α [SMD=–2.75, 95%CI (–3.84, –1.66), P<0.000 01], and C-reactive protein [SMD=–2.55, 95%CI (–3.83, –1.26), P=0.000 1], as well as a higher level of partial pressure of oxygen in arterial blood [MD=15.34 mm Hg (1 mm Hg=0.133 kPa), 95%CI (6.38, 24.31) mm Hg, P=0.000 8] appeared after the combined treatment.ConclusionBased on the conventional therapy, the treatment of fiberoptic bronchoscopy can improve the efficacy, shorten the hospital stay, relieve the systemic inflammatory responses, and improve the oxygenation of SAP patients.
Objective To investigate the effects of high dose ulinastatin with lung protective ventilatory strategies on respiratory function and prognosis in critical disease patients combined with acute lung injury/acute respiratory distress syndrome. Methods Using retrospective analysis, we involved the critical disease patients combined with ALI/ARDS in ICU of The Second Affiliated Hospital of Anhui Medical University. According to whether they were treated with high dose ulinastatin with lung protective ventilatory strategies or not, the patients were divided into the treatment group and the control group. Then pulmonary vascular permeability index (PVPI), extravascular lung water index (EVLWI), oxygenation index, length of SIRS, length of stay in ICU and APACHE Ⅱ score were observed. Statistic analysis was conducted using SPSS 19.0 software. Results A total of 24 patients were included, 13 cases in the treatment group and 11 cases in the control group. After 72 h, PVPI (P=0.016), EVLWI (P=0.045), length of SIRS (P=0.002), length of stay in ICU (P=0.024) and APACHE Ⅱ score (P=0.002) decreased significantly, while oxygenation index (P=0.004) increased significantly in the treatment group compared with the control group. Conclusion High dose ulinastatin with lung protective ventilatory strategies decreased lung capillary permeability, reduced lung blood capillary leakage and extravascular lung water, resulted in the improvement of lung oxygenation function, decreased of length of stay in ICU and the improvement of prognosis in critical disease patients combined with acute lung injury/acute respiratory distress syndrome.
ObjectivesTo identify the clinical characteristics and prognosis for CRKP (Carbapenem-resistant Klebsiella pneumonia, CRKP) infection among ICU patients in the Second Affiliated Hospital of Anhui Medical University. MethodsWe conducted a retrospectively analysis in which 19 patients infected by CRKP with another 21 CSKP (Carbapenem-sensitive Klebsiella pneumoniae, CSKP) infected patients from January 2017 to April 2018. Risk factors for CRKP infection were assessed. ResultsThe lower respiratory tract is the most common site of CRKP infection in our department. CRKP infection was associated with several clinical symptoms, particularly a higher incidence of sepsis shock (χ2=8.338, P=0.004), more application of the combined medicine (χ2=26.3, P<0.001), prolonged hospital stays (χ2=–2.217, P=0.027) and more expenses on antibiotics (χ2=12.855, P=0.005), and the declined survival rates in 14 days (χ2=4.269, P=0.039) and 21 days (χ2 =5.647, P=0.017). The resistance rate of CRKP strains was high, however no resistance to tegafycline was found. The risk factors of CRKP infection included three generations of cephalosporin and/or hydrocarbonase antibiotics exposure (χ2 =6.388, P=0.041), exposure time of three generations of cephalosporin (U=–2.187, P=0.029), exposure time of hydrocarbonase antibiotics (U=–2.103, P=0.035), tracheal intubation (χ2=6.352, P=0.012), tracheotomy (χ2 =4.821, P=0.028), SOFA score (t=4.505, P<0.001) and Charlson comorbidity index (t=3.041, P=0.004). The SOFA score was the only factor independently associated with CRKP bacteremia (P=0.02). ConclusionsCRKP infections in ICU directly affect the course of disease, survival time and treatment expenses of patients. Therefore, monitoring bacterial resistance, rational use of antibiotics, and protection of the immune function are of great significance for prevention and treatment of CRKP infection.
