Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay / In-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay

Introducción: los pacientes con COVID-19 ingresan en mayor proporción a asistencia respiratoria mecánica, aumentando: el riesgo de neumonía asociada a ventilador (NAV) las tasas de mortalidad, los días de permanencia en las unidades de terapia intensiva (UCI) y los costos sanitarios. Objetivo: determinar la Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay durante los años 2020 a 2021. Metodología: estudio analítico de tipo cohorte retrospectiva. Se registraron variables demográficas, comorbilidades, puntajes en scores de gravedad como el APACHE II al ingreso, la cifra más baja de oxigenación durante la internación expresado por la PaO2 / FIO2, días de ventilación, colocación en decúbito prono, traqueotomía, medidas terapéuticas farmacológicas y no farmacológicas, días de internación, así como las complicaciones y la mortalidad. Resultados: fueron incluidos 214 pacientes, 135 ingresaron a asistencia respiratoria mecánica (ARM) de los cuales 58 (42,9 %) desarrollaron NAV, con edad mediana de 52 años (40-60). Los microorganismos de NAV fueron cocos Gram negativos en 98,3 %, incluyendo Acinetobacter baumanii en 46,5 %, Klebsiella pneumoniae en 22,8 %, Pseudomona aeruginosa en 15,5 % y 5,2 % Stenotrophomona maltofilia. La mortalidad intrahospitalaria fue del 44,8 %. Los menores de 50 años tienen una sobrevida mayor que los mayores (34 días vs 22 días, con p de 0,026). Conclusión: la mortalidad intrahospitalaria fue del 44,8 %. La edad fue un factor de riesgo independiente para la mortalidad en pacientes con NAV, por lo que los profesionales de la salud deben estar atentos a la posibilidad de NAV en pacientes que requieren asistencia respiratoria mecánica, especialmente en pacientes mayores de 50 años.

Introduction: patients with COVID-19 are more likely to require mechanical ventilation, which increases the risk of ventilator-associated pneumonia (VAP), mortality rates, length of stay in intensive care units (ICUs), and healthcare costs. Objective: to determine the in-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay during the years 2020 to 2021. Methodology: this is a retrospective cohort analytical study. Demographic variables, comorbidities, severity scores such as APACHE II on admission, the worst oxygenation during hospitalization expressed by PaO2/FiO2, days of ventilation, prone position, tracheostomy, pharmacological and non-pharmacological therapeutic measures, days of hospitalization, as well as complications and mortality were recorded. Results: a total of 214 patients were included, 135 were admitted to mechanical ventilation (MRA), of which 58 (42.9%) developed VAP, with a median age of 52 years (40-60). VAP microorganisms were Gram-negative cocci in 98.3%, including Acinetobacter baumanii in 46.5%, Klebsiella pneumoniae in 22.8%, Pseudomona aeruginosa in 15.5%, and Stenotrophomona maltophilia in 5.2%. In-hospital mortality was 44.8%. Those under 50 years of age have a longer survival than those older (34 days vs. 22 days, with p of 0.026). Conclusion: the overall mortality rate was 44.8%. Age was an independent risk factor for mortality in patients with VAP, so healthcare professionals should be aware of the possibility of VAP in patients who require mechanical ventilation, especially in patients over 50 years of age.

Salud bucal en pacientes en estado crítico / Critical patient oral health

Fundamento: La salud bucal y sus cuidados son importantes en la atención sanitaria de pacientes en estado crítico. Objetivo: Proporcionar una visión general de los vínculos entre la salud bucal y los resultados adversos en la evolución de los pacientes en estado crítico. Metodología: Esta revisión narrativa se realizó en Google Académico, PubMed/Medline y SciELO, con los descriptores salud bucal, cuidados críticos, respiración artificial y neumonía asociada al ventilador, consultados en el DeCS. Se seleccionaron artículos a texto completo en español e inglés de revistas arbitradas por pares y de los últimos 5 años. Resultados: La disbiosis y la mala higiene bucales propician la aparición y desarrollo de enfermedades bucales que, a su vez, favorecen la incidencia de enfermedades respiratorias bajas como la neumonía asociada al ventilador en pacientes en estado crítico. Dentro de los factores vinculantes están la aspiración de secreciones bucales con bacterias patógenas que colonizan el tracto respiratorio inferior y los trastornos nutricionales que reducen el sistema defensivo. Aunque existen algunas discrepancias, la mayoría de los estudios apoyan las medidas de cuidado bucal en los pacientes en estado crítico. Conclusiones: La salud y cuidados bucales son claves para un desenlace clínico más favorable en los pacientes en estado crítico.

Background: Oral health and oral health care are important in the health care of critically ill patients. Objective: To provide an overview of the relationship between oral health and adverse outcomes in critically ill patients. Methodology: This narrative revision was conducted in Google Scholar, PubMed/Medline and SciELO, with the descriptors oral health, critical care, artificial respiration and ventilator-associated pneumonia consulted in the DeCS. Full-text articles in Spanish and English from peer-reviewed journals and from the last 5 years were selected. Results: Dysbiosis and poor oral hygiene promote the incidence and development of oral diseases, which in turn promote the incidence of lower respiratory system diseases such as ventilator-associated pneumonia in critically ill patients. Among the factors involved are aspiration of oral secretions with pathogenic bacteria that colonize the lower respiratory tract, and nutritional deficiencies that compromise the immune system. Although there are some discrepancies, most studies support oral care practices in critically ill patients. Conclusions: The health and care of the oral cavity is the key to a more favorable outcome for critically ill patients.

Infections in Critically Ill Children

Health care–associated infections (HAI) directly influence the survival of children in pediatric intensive care units (PICU), the most common being central line–associated bloodstream infection (CLABSI) 25–30%, followed by ventilator-associated pneumonia (VAP) 20–25%, and others such as catheter-associated urinary tract infection (CAUTI) 15%, surgical site infection (SSI) 11%. HAIs complicate the course of the disease, especially the critical one, thereby increasing the mortality, morbidity, length of hospital stay, and cost. The incidence of HAI in Western countries is 6.1–15.1% and in India, it is 10.5 to 19.5%. The advances in healthcare practices have reduced the incidence of HAIs in the recent years which is possible due to strict asepsis, hand hygiene practices, surveillance of infections, antibiotic stewardship, and adherence to bundled care. The burden of drug resistance and emerging infections are increasing with limited antibiotics in hand, is still a dreadful threat. The most common manifestation of HAIs is fever in PICU, hence the appropriate targeted search to identify the cause of fever should be done. Proper isolation practices, judicious handling of devices, regular microbiologic audit, local spectrum of organisms, identification of barriers in compliance of hand hygiene practices, appropriate education and training, all put together in an efficient and sustained system improves patient outcome.

Evaluation of the combination treatments with intravenous fosfomycin for carbapenem-resistant Klebsiella pneumoniae

SUMMARY OBJECTIVE: The aim of this study was to evaluate the combination treatments with intravenous fosfomycin for carbapenem-resistant Klebsiella pneumoniae infections in a tertiary-care center. METHODS: Between December 24, 2018 and November 21, 2022, adult patients diagnosed with bloodstream infection or ventilator-associated pneumonia due to culture-confirmed carbapenem-resistant Klebsiella pneumoniae in the anesthesiology and reanimation intensive care units were investigated retrospectively. RESULTS: There were a total of 62 patients fulfilling the study inclusion criteria. No significant difference was recorded in 14- and 30-day mortality among different types of combination regimens such as fosfomycin plus one or two antibiotic combinations. Hypokalemia (OR:5.651, 95%CI 1.019-31.330, p=0.048) was found to be a significant risk factor for 14-day mortality, whereas SOFA score at the time of diagnosis (OR:1.497, 95%CI 1.103-2.032, p=0.010) and CVVHF treatment (OR:6.409, 95%CI 1.395-29.433, p=0.017) were associated with 30-day mortality in multivariate analysis. CONCLUSION: In our study, high mortality rates were found in patients with bloodstream infection or ventilator-associated pneumonia due to carbapenem-resistant Klebsiella pneumoniae, and no significant difference was recorded in 14- and 30-day mortality among different types of combination regimens such as fosfomycin plus one or two antibiotic combinations.

Research progress on the role of respiratory microbiome in ventilator-associated pneumonia / 中华危重病急救医学

Respiratory microbiome is extensively involved in human life activities and affects lung health and disease states through metabolism and immune regulation. Based on 16S rRNA gene sequencing and other methods, it is obvious that the diversity and the changes in the structure of respiratory microbiome and the dominant proliferation of pathogens are strongly related to the occurrence, development and clinical prognosis of ventilator-associated pneumonia (VAP). The mechanism by which respiratory microbiota promotes the clearance of pathogens may include the following aspects: ① pre-stimulating innate immune system to increase the number of immune effector cells; ② regulating pattern recognition receptor (PRR) to moderately promote the production of cytokines; ③ inducing the differentiation of neutrophils into specific subtypes and increasing the expression of antimicrobial genes; ④ producing free fatty acids and organic compounds that are capable of positively modulating the immune system. In conclusion, intervention of microbiome is beneficial to VAP patients. Therefore, this review illustrates the changes of respiratory flora in VAP and its effect on host immunity. At the same time, based on the review of the adjuvant treatment of VAP with probiotics, we put forward the prospect of respiratory commensal bacteria as a new clinical probiotic, in order to deepen the clinical understanding of the role of respiratory flora in VAP, and then provide new ideas for the evaluation of treatment and prognosis.

Effect of prone position management on preventing ventilator-associated pneumonia in children with congenital heart disease complicated with acute respiratory distress syndrome / 中国实用护理杂志

Objective:To develop a prone position management program and evaluate its effectiveness in preventing ventilator-associated pneumonia (VAP) in children with congenital heart disease combined with acute respiratory distress syndrome, in order to provide experience for clinical application.Methods:This was a quasi-experimental study. Convenient sampling method was used to select children with congenital heart defect who underwent mechanical ventilation in the Cardiothoracic Surgical Care Unit of Shanghai Children′s Medical Center, Shanghai Jiao Tong University, School of Medicine from June 2018 to December 2021 as the study subjects. The control group consisted of 80 hospitalized children from June 2018 to December 2019. They were used general nursing interventions to prevent VAP. The 42 hospitalized children from January 2020 to December 2021 were the intervention group, who usd the prone position management program on the basis of the control group. The differences in the incidence of VAP, duration of mechanical ventilation, duration of ICU stay, oxygenation index and the incidence of adverse events between the two groups were compared.Results:The incidence of VAP and mechanical ventilation duration in the intervention group were 4.8% (2/42) and 67.50 (55.00/101.50), which were lower than 35.0% (28/80) and 92.50 (68.00/142.00) of the control group, and the differences were statistically significant ( χ2=11.98, Z=3.40, both P<0.01). And the trend of increasing oxygenation index with the intervention group was better than the control group ( F=8.38, P<0.05). There was no statistical difference in the incidence of adverse events between the two groups (all P>0.05). Conclusions:The application of prone ventilation program with congenital heart disease children complicated with acute respiratory distress syndrome is safe and can significantly improve the oxygenation index, shorten the duration of mechanical ventilation and reduce the incidence of VAP.

Postoperative Period of Myocardial Revascularization Surgery: Retrospective Cohort Study of a Single Center

ABSTRACT Introduction: Risk factors and postoperative complications can worsen the condition of patients undergoing coronary artery bypass grafting; some of these factors and complications are closely related to mortality rate. Objective: To describe clinical factors and outcomes related to mortality of patients undergoing coronary artery bypass grafting and on invasive mechanical ventilation. Methods: This is a single-center retrospective data analysis of patients who underwent coronary artery bypass grafting on invasive mechanical ventilation between 2013 and 2019. Data regarding clinical characteristics, postoperative complications, intensive care unit and mechanical ventilation time, and their relationship with mortality were analyzed. Results: Four hundred seventy-two patients who underwent coronary artery bypass grafting entered the study. Their mean age was 62.3 years, and mean body mass index was 27.3. The mortality rate was 4%. Fifty percent of the patients who had ventilator-associated pneumonia died. Considering the patients who underwent hemotherapy and hemodialysis, 20% and 33% died, respectively. Days of intensive care unit stay and high Acute Physiology and Chronic Health Evaluation score and Simplified Acute Physiology Score were significantly related to death. Conclusion: Factors and clinical conditions such as the patients' age, associated comorbidities, the occurrence of ventilator-associated pneumonia, length of stay in the intensive care unit, and mechanical ventilation time are related to higher mortality in patients undergoing coronary artery bypass grafting.

Randomized Control Study of Nebulized Colistin as an Adjunctive Therapy in Ventilator?Associated Pneumonia in Pediatric Postoperative Cardiac Surgical Population

Background:Ventilator?associated pneumonia (VAP) with multidrug?resistant (MDR) gram negative organisms is a common problem in intensive care unit (ICU). Aerosolized antibiotics enhance the efficacy of systemic antibiotics when added as adjuvants. Aim: The primary objective of the study was to compare the clinical and bacteriological outcome of patients with VAP who were administered intravenous (IV) antibiotics alone with those patients who were treated with adjunctive nebulized colistin (NC) along with IV antibiotics. The secondary objective was to study the occurrence of any adverse events during colistin nebulization. Settings and Design: The study was a prospective, randomized, double?blinded controlled study conducted at a tertiary?care teaching institution. Materials and Methods: Ninety?eight children from surgical ICU aged less than 12 years who were diagnosed with VAP due to gram negative bacteria following cardiac surgery were chosen and divided randomly into two groups. The experimental group (NC group) was treated with systemic antibiotics along with NC, whereas the control group (NS group) was administered systemic antibiotics with nebulized normal saline (NS). Clinical and bacteriological outcomes were noted. Statistical analysis was done using SPSS Version 20.0 software. The patient characteristics were compared using independent Student’s t test and Chi?square test. Results: There was a statistically significant reduction in the duration of mechanical ventilation, postoperative ICU and hospital stay (P < 0.05) in the NC group compared with the NS group. Conclusion: Aerosolized colistin may be considered as an adjunct to systemic IV antibiotics in pediatric patients with VAP due to gram negative bacteria susceptible to colistin.

Tecnologia para prevenção de pneumonia associada à ventilação mecânica em unidade de terapia intensiva adulto / Technology for the prevention of ventilator-associated pneumonia in an adult intensive care unit

Resumo: A Pneumonia Associada à Ventilação (PAV) é uma das infecções relacionadas à assistência à saúde mais incidentes nas Unidades de Terapia Intensiva (UTI), e está relacionada com aumento do tempo de internação, os custos hospitalares e a mortalidade. Os bundles, ou conjunto de medidas preventivas, são tecnologias em saúde, cuja implementação em UTI está relacionada à diminuição da Densidade de Incidência (DI) de PAV, tempo de ventilação e internação hospitalar. Objetivo: implementar um bundle de prevenção à PAV, por meio de intervenção educativa, com uso de tecnologias educacionais, junto à equipe multiprofissional de uma UTI adulto de um hospital público do Paraná, localizado no litoral do estado. Método: estudo quase-experimental do tipo antes e depois, de intervenção educativa, realizado de janeiro a maio de 2022, composto por três fases: pré-intervenção, intervenção e pós-intervenção. A intervenção ocorreu no mês de março de 2022, com 70 profissionais da UTI, dividida em três encontros, e utilizou como tecnologias educacionais: aula expositiva-dialogada, vídeos, gamificação de estudos de caso, banner, infográfico e demonstração da prática em manequim. Para categorização dos profissionais, utilizou-se de questionário entregue no momento da intervenção educativa. Incluíram-se os profissionais da equipe multiprofissional da UTI, enfermeiros, técnicos de enfermagem, médicos e fisioterapeutas. Inseriram-se os pacientes adultos, em VM, internados na UTI e foram analisados os respectivos prontuários. Os dados foram coletados por meio de check-list de adesão ao bundle de PAV, por paciente, e preenchido pelas pesquisadoras, através de observação direta não participante dos procedimentos realizados aos pacientes incluídos e análise de prontuário destes. Os dados foram tabulados e lançados em planilha do programa Excel®, com análise estatística descritiva, com frequências absolutas, relativas e média. Resultados: a implementação do bundle por meio de intervenção educativa, com uso de tecnologias educacionais, possibilitou debate, envolvimento e interação entre os profissionais participantes, com troca de experiências, contribuições e discussão da prática assistencial. Realizaram-se 488 observações, 61 pacientes foram incluídos e 26 desenvolveram PAV. Registraram-se 33 óbitos (sendo 12 na fase pré e 21 na fase pós), destes, 19 tinham PAV. A DI de PAV da fase pré-intervenção foi de 25,58 PAV/VM-dia e da fase pós-intervenção foi de 31,74 PAV/ VM-dia. Houve aumento da taxa de adesão geral ao bundle na fase pós-intervenção, que foi de 67,64%, em comparação com a fase pré (33%). O item do bundle com maior adesão foi a manutenção da pressão do cuff (93,03%), seguido da higiene oral (82,99%), cabeceira elevada (78,07%), manutenção do sistema de ventilação mecânica conforme as recomendações vigentes no país (69,05%), redução da sedação (67,0%) e verificação da possibilidade de extubação (38,72%). Conclusão: a implementação do bundle, por meio de intervenção educativa, com uso de tecnologias educacionais, somada à vigilância à beira leito da realização das medidas de prevenção à PAV, demonstrou aumento da adesão ao bundle após a intervenção, porém não houve redução da DI de PAV. Podem existir explicações alternativas, como ausência de protocolos de sedação e teste de respiração espontânea, convergências carentes de intervenção.

Abstract: Ventilator-Associated Pneumonia (VAP) is one of the most frequent healthcare-associated infections in Intensive Care Units (ICU), and is related to increased length of stay, hospital costs and mortality. Bundles, or a set of preventive measures, are health technologies whose implementation in the ICU is related to the decrease in VAP Incidence Density (DI), ventilation time and hospital stay. Objective: to implement a VAP prevention bundle, through educational intervention, with the use of educational technologies, together with the multidisciplinary team of an adult ICU of a public hospital in Paraná, located on the coast of the state. Method: a quasi-experimental before-and-after study of educational intervention, carried out from January to May 2022, consisting of three phases: pre-intervention, intervention and post-intervention. The intervention took place in March 2022, with 70 ICU professionals, divided into three meetings, and used as educational technologies: expository-dialogued class, videos, gamification of case studies, banner, infographic and demonstration of the practice on a mannequin. For categorization of professionals, a questionnaire delivered at the time of the educational intervention was used. Professionals from the ICU multidisciplinary team, nurses, nursing technicians, physicians and physiotherapists were included. Adult patients in VM, admitted to the ICU were included and their medical records were analyzed. Data were collected through a check-list of adherence to the VAP bundle, per patient, and filled in by the researchers, through direct observation of the non-participant of the procedures performed on the included patients and analysis of their medical records. The data were tabulated and entered in an Excel® spreadsheet, with descriptive statistical analysis, with absolute, relative and average frequencies. Results: the implementation of the bundle through educational intervention, using educational technologies, enabled debate, involvement and interaction among the participating professionals, with exchange of experiences, contributions and discussion of care practice. There were 488 observations, 61 patients were included and 26 developed VAP. There were 33 deaths (12 in the prephase and 21 in the post-phase), of which 19 had VAP. The VAP DI in the pre-intervention phase was 25.58 VAP/MV-day and in the post-intervention phase it was 31.74 VAP/MV-day. There was an increase in the overall adherence rate to the bundle in the post-intervention phase, which was 67.64%, compared to the pre-phase (33%). The bundle item with the highest adherence was maintenance of cuff pressure (93.03%), followed by oral hygiene (82.99%), elevated headboard (78.07%), maintenance of the mechanical ventilation system as recommended in the country (69.05%), reduction of sedation (67.0%) and verification of the possibility of extubation (38.72%). Conclusion: the implementation of the bundle, through educational intervention, with the use of educational technologies, added to the surveillance at the bedside of the implementation of VAP prevention measures, showed an increase in adherence to the bundle after the intervention, but there was no reduction in DI of PAV. There may be alternative explanations, such as the absence of sedation protocols and spontaneous breathing tests, convergences lacking intervention.

Efficiency of Nursing Care Package on Expected Outcome in Prevention of Ventilator-Associated Pneumonia among Ventilated Clients in ETCM Hospital Kolar

Pneumonia has accounted for approximately 15 percent of all hospital-associated infections and 27 percent and 24 percent of all infections acquired in the medical intensive-care unit (ICU) and coronary care unit, respectively. It has been the second most common hospital-associated infection after that of the urinary tract. Because of this tremendous risk, in the last two decades, most of the research on hospital-associated pneumonia has focused on ventilator-associated pneumonia. This study was aimed to assess effi ciency of nursing care package on expected outcome regarding prevention of ventilator associated pneumonia among ventilated clients. A quantitative research approach with quasi experimental research design with pre-and post-test with equivalent control group design was used to carry out the study. Ventilated clients from selected hospitals who were fulfi lling the inclusion criteria were selected by using non-probability convenient sampling technique. Total 40 (20 experimental and 20 control group) size sample was included in the study. In experimental group, majority (50%) had mild infection and only 15 percent had no infection in pre-test; in post-test majority (75%) had no infection and only 25 percent had mild infection and no patient had severe infection. It showed that delivery of nursing care package is effective in decreasing ventilator associated pneumonia. In control group, majority (50%) had mild infection and only 10 percent had no infection in pre-test and in post-test majority (40%) had mild infection and 60 percent had severe infection and no patient had severe infection. As nursing care package was not delivered, the infected cases increased. The effi ciency of nursing care package on expected outcome regarding prevention of ventilator-associated pneumonia between experimental groups was statistically signifi cant and in control group it was not signifi cant. The delivered nursing care package on ventilator-associated pneumonia among ventilated clients proved its benefi cial effects in controlling infection level and preventing ventilator-associated pneumonia at intensive care units. This study confi rmed that nursing care package for ventilated clients can prevent infection and cut short long stay in intensive care units.

Mediante un modelo de regresión logística binaria se identificaron como predictores independientes para el desarrollo de NAV: Sobrecarga hídrica (OR=5,537; IC95%: 1,903 - 16,113; p = 0,002), supresor de acidez gástrica (OR=5,360; IC95%: 1,584 - 18,136; p = 0,007), nutrición enteral (OR=2,354; IC95%: 1,079 - 5,136; p = 0,032), reintubación (OR=4,423; IC95%: 1,821 - 10,743; p = 0,001) y recibir más de dos transfusiones de glóbulos rojos (OR=2,267; IC95%: 1,002 - 5,127; p = 0,049). Además, los casos con NAV presentaron más días en la unidad de cuidados intensivos (UCI) (7,5 ± 3,5 vs. 10,8 ± 4,6 días; p < 0,0001), mayor tiempo de duración total de ventilación mecánica (4,4 ± 2,3 vs. 7,3 ± 3,8; p < 0,0001) y mayor mortalidad en UCI (10,9% vs. 34,9%; p < 0,0001). Conclusión: La sobrecarga hídrica, el uso de supresores de acidez gástrica, la nutrición enteral, la reintubación y recibir más de dos transfusiones de glóbulos rojos son factores de riesgo para desarrollar NAV.

ABSTRACT Introduction: Ventilator-associated pneumonia (VAP) is the second most common infection acquired in hospitals, after bloodstream infection, and is associated with high mortality and involves a high impact on the economic burden of medical care. of these patients. Objective: To identify risk factors for VAP in critically-ill children. Materials and Methods: This was a case-control study carried out at the "Dr. Agustín Zubillaga" University Hospital (Barquisimeto, Lara State, Venezuela), between 2017 and 2019. We used binary logistic regression. Results: A total of 172 mechanically ventilated children were included in the analysis. Using a binary logistic regression model, the following were identified as independent predictors for the development of VAP: Fluid overload (OR=5.537; 95% CI: 1.903 - 16.113; p = 0.002), gastric acidity suppression (OR=5.360; 95% CI: 1.584 - 18.136; p = 0.007), enteral nutrition (OR=2.354; 95% CI: 1.079 - 5.136; p = 0.032), reintubation (OR=4.423; 95% CI: 1.821 - 10.743; p = 0.001) and receiving more than two transfusions of red blood cells (OR=2.267; 95% CI: 1.002 - 5.127; p = 0.049). In addition, the cases with VAP presented longer length-of-stay in the intensive care unit (ICU) (7.5 ± 3.5 vs. 10.8 ± 4.6 days; p < 0.0001), a longer total duration of mechanical ventilation (4.4 ± 2.3 vs. 7.3 ± 3.8; p < 0.0001) and higher mortality in the ICU (10.9% vs. 34.9%; p < 0.0001). Conclusion: Fluid overload, the use of gastric acidity suppressants, enteral nutrition, reintubation and receiving more than two red blood cell transfusions are risk factors for developing VAP.

Design of a device for preventing pollution and air pollution in the pipeline joint of the ventilator / 中华危重病急救医学

Ventilators are currently the most commonly used auxiliary mechanical ventilation equipment in clinical practice, and play an important role in the treatment of hypoxemia. Ventilator-associated pneumonia (VAP) is a special type of pulmonary parenchymal inflammation of nosocomial infection in patients with mechanical ventilation, which leads the increase of mortality and affects the prognosis of patients. The non-standard management of ventilator pipeline joints and the aerosol formed by bacterial condensate splashed from ventilator pipeline pollute the air, resulting in cross infection, which are the important reasons for VAP. The existing ventilator pipeline joint cap can achieve the effect of preventing pollution, but the clinical application compliance is not high. Based on the above factors, teachers, students and medical staff of the School of Public Health and Management, Guangxi University of Chinese Medicine and other units have designed a device for preventing pollution and air pollution of the ventilator pipeline joint, and obtained the national utility model patent of China (ZL 2020 2 1361981.X). The device is composed of a model lung, a mask body, a suspension part and a beam mouth part, etc. The use method is simple, and can be applied to the pollution avoidance of invasive ventilator and non-invasive ventilator pipeline joints, to reduce the occurrence of VAP in patients and the occupational exposure of medical staff.

Bacterial flora of biofilm in the endotracheal tube of mechanically ventilated neonates and its relationship with ventilator-associated pneumonia / 中华传染病杂志

Objective:To explore the relationship between endotracheal tube-bacterial biofilm (ETT-BF) in mechanically ventilated neonates and ventilator-associated pneumonia (VAP).Methods:A total of 30 mechanically ventilated neonates whose mechanical ventilation time were ≥48 h in the Department of Neonatology in The Second Affiliated Hospital of Wenzhou Medical University from January 2019 to January 2020 were included.According to the indwelling time of endotracheal tube, all cases were divided into three groups including group A(two to six days), group B(seven to 14 days) and group C (over 14 days). The morphological results of ETT-BF were scanned by scanning electron microscope (SEM). The incidence of VAP, the positive rates of strains isolated from endotracheal tube surface and lower respiratory tract secretion, the detection of strains and drug resistance were analyzed. Chi-squared test were used for statistical analysis.Results:The results of SEM showed that sheet matrix could be observed on the surface of the inner cavity of endotracheal tube in three days of tracheal catheter retention, and cocci adhered to it in four days. With prolonged indwelling time of endotracheal tube, the structure of bacterial biofilm (BF) had improved.The positive rate of strains isolated from the secretion of lower respiratory tract in 30 neonates was 23.3%(7/30) and all of them were Gram-negative bacteria. There was no patient developed VAP in group A, while there were two patients with VAP in group B, and five patients with VAP in group C. The incidences of VAP in the three groups were statistically significant ( χ2=10.82, P=0.004). There was no significant difference in the positive rate of strains isolated from the surface of endotracheal tube under different indwelling time in 30 cases ( χ2=1.03, P=0.598). Among of 13 neonates in group A, there were seven strains isolated from ETT-BF, mainly Gram-positive bacteria which turned out to be mainly Gram-negative bacteria with the prolongation of endotracheal tube indwelling time. Of the seven VAP cases, strains isolated from the lower respiratory tract secretion were consistent with the strains isolated from the surface of the corresponding endotracheal tube in five cases, which were Serratia liquefaciens, Klebsiella acidogenes, Serratia marcescens, Flavobacterium meningosepticum and Stenotrophomonas maltophilia, and the drug resistance was consistent. Conclusions:The colonization bacteria of early ETT-BF may come from the upper respiratory tract, with less migration which rarely causes VAP. With the prolongation of endotracheal tube indwelling time, the incidence of VAP in neonates increases. The same pathogen can be found in the ETT-BF and lower respiratory tract secretion. The source of pathogen needs further study.

Design and application of flushing device of a totally enclosed sputum suction tube for reducing the incidence of ventilator-associated pneumonia / 中华危重病急救医学

Ventilator-associated pneumonia (VAP) is one of the most common infectious diseases in patients undergoing mechanical ventilation in intensive care unit (ICU). Although the use of closed sputum suction tube for sputum suction is the most common nursing measure for patients with tracheal intubation in ICU, and it is also an important measure to reduce the occurrence of VAP, the existing clinical technology still needs to use external flushing solution for humidification and flushing. In the process of use, the flushing operation has the risk that the amount of flushing fluid cannot be controlled, resulting in a large amount of flushing fluid entering the patient's airway, causing the patient to suffocate. The sputum attached to the wall of the sputum suction tube cannot be completely flushed, and the prolonged retention of the sputum leads to the proliferation of colonized bacteria, aggravating the infection of patients. Repeated pipe flushing not only increases consumables, but also increases the workload of medical staff. For this reason, the author has designed a fully enclosed sputum suction tube flushing device, which has obtained the National Utility Model Patent of China (patent number: CN 2019 2 1198740.5). This device is an integrated design, and the materials used for sputum suction, humidification and flushing are fully enclosed, without air exposure, and can be operated strictly without bacteria. Pulse flushing with syringe can clean the sputum attached to the inner wall and reduce the incidence of VAP. The volume of flushing fluid can be effectively controlled during use to ensure patient safety and reduce waste. It is worth popularizing and applying in clinical practice to optimize the operation steps and reduce the workload of medical staff.

Secondary infections in a cohort of patients with COVID-19 admitted to an intensive care unit: impact of gram-negative bacterial resistance

ABSTRACT Some studies have shown that secondary infections during the COVID-19 pandemic may have contributed to the high mortality. Our objective was to identify the frequency, types and etiology of bacterial infections in patients with COVID-19 admitted to an intensive care unit (ICU) and to evaluate the results of ICU stay, duration of mechanical ventilation (MV) and in-hospital mortality. It was a single-center study with a retrospective cohort of patients admitted consecutively to the ICU for more than 48 h between March and May 2020. Comparisons of groups with and without ICU- acquired infection were performed. A total of 191 patients with laboratory-confirmed COVID-19 were included and 57 patients had 97 secondary infectious events. The most frequent agents were Acinetobacter baumannii (28.9%), Pseudomonas aeruginosa (22.7%) and Klebsiella pneumoniae (14.4%); multi-drug resistance was present in 96% of A. baumannii and in 57% of K. pneumoniae. The most prevalent infection was ventilator-associated pneumonia in 57.9% of patients with bacterial infections, or 17.3% of all COVID-19 patients admitted to the ICU, followed by tracheobronchitis (26.3%). Patients with secondary infections had a longer ICU stay (40.0 vs. 17 days; p < 0.001), as well as a longer duration of MV (24.0 vs 9.0 days; p= 0.003). There were 68 (35.6%) deaths overall, of which 27 (39.7%) patients had bacterial infections. Among the 123 survivors, 30 (24.4%) had a secondary infections (OR 2.041; 95% CI 1.080 - 3.859). A high incidence of secondary infections, mainly caused by gram-negative bacteria has been observed. Secondary infections were associated with longer ICU stay, MV use and higher mortality.
