ABSTRACT Data on the effectiveness of ceftazidime-avibactam (CAZ-AVI) in critically ill, mechanically ventilated patients are limited. The present retrospective observational cohort study, which was conducted in two general intensive care units (ICUs) in central Greece, compared critically ill, mechanically ventilated patients suffering from carbapenem-resistant Enterobacteriaceae (CRE) infections receiving CAZ-AVI to patients who received appropriate available antibiotic therapy. Clinical and microbiological outcomes and safety issues were evaluated. A secondary analysis in patients with bloodstream infections (BSIs) was conducted. Forty-one patients that received CAZ-AVI (the CAZ-AVI group) were compared to 36 patients that received antibiotics other than CAZ-AVI (the control group). There was a significant improvement in the Sequential Organ Failure Assessment (SOFA) score on days 4 and 10 in the CAZ-AVI group compared to that in the control group (P = 0.006, and P = 0.003, respectively). Microbiological eradication was accomplished in 33/35 (94.3%) patients in the CAZ-AVI group and 21/31 (67.7%) patients in the control group (P = 0.021), and clinical cure was observed in 33/41 (80.5%) versus 19/36 (52.8%) patients (P = 0.010), respectively. The results were similar in the BSI subgroups for both outcomes (P = 0.038 and P = 0.014, respectively). The 28-day survival was 85.4% in the CAZ-AVI group and 61.1% in the control group (log-rank test = 0.035), while there were 2 and 12 relapses in the CAZ-AVI and control groups, respectively (P = 0.042). A CAZ-AVI-containing regime was an independent predictor of survival and clinical cure (odds ratio [OR] = 5.575 and P = 0.012 and OR = 5.125 and P = 0.004, respectively), as was illness severity. No significant side effects were recorded. In conclusion, a CAZ-AVI-containing regime was more effective than other available antibiotic agents for the treatment of CRE infections in the high-risk, mechanically ventilated ICU population evaluated.

BACKGROUNDHealthcare-associated infections (HAIs) cause significant morbidity in critically ill patients. An underappreciated but potentially modifiable risk factor for infection is sedation strategy. Recent trials suggest that choice of sedative agent, depth of sedation, and sedative management can influence HAI risk in mechanically ventilated patients.OBJECTIVETo better characterize the relationships between sedation strategies and infection.METHODSSystematic literature review.RESULTSWe found 500 articles and accepted 70 for review. The 3 most common sedatives for mechanically ventilated patients (benzodiazepines, propofol, and dexmedetomidine) have different pharmacologic and immunomodulatory effects that may impact infection risk. Clinical data are limited but retrospective observational series have found associations between sedative use and pneumonia whereas prospective studies of sedative interruptions have reported possible decreases in bloodstream infections, pneumonia, and ventilator-associated events.CONCLUSIONInfection rates appear to be highest with benzodiazepines, intermediate with propofol, and lowest with dexmedetomidine. More data are needed but studies thus far suggest that a better understanding of sedation practices and infection risk may help hospital epidemiologists and critical care practitioners find new ways to mitigate infection risk in critically ill patients.Infect Control Hosp Epidemiol 2016;1–9

Abstract Background Analgesia and sedation therapy are commonly used for critically ill patients, especially mechanically ventilated patients. From the initial nonsedation programs to deep sedation and then to on-demand sedation, the understanding of sedation therapy continues to deepen. However, according to different patient’s condition, understanding the individual patient’s depth of sedation needs remains unclear. Methods The public open source critical illness database Medical Information Mart for Intensive Care III was used in this study. Latent profile analysis was used as a clustering method to classify mechanically ventilated patients based on 36 variables. Principal component analysis dimensionality reduction was used to select the most influential variables. The ROC curve was used to evaluate the classification accuracy of the model. Results Based on 36 characteristic variables, we divided patients undergoing mechanical ventilation and sedation and analgesia into two categories with different mortality rates, then further reduced the dimensionality of the data and obtained the 9 variables that had the greatest impact on classification, most of which were ventilator parameters. According to the Richmond-ASS scores, the two phenotypes of patients had different degrees of sedation and analgesia, and the corresponding ventilator parameters were also significantly different. We divided the validation cohort into three different levels of sedation, revealing that patients with high ventilator conditions needed a deeper level of sedation, while patients with low ventilator conditions required reduction in the depth of sedation as soon as possible to promote recovery and avoid reinjury. Conclusion Through latent profile analysis and dimensionality reduction, we divided patients treated with mechanical ventilation and sedation and analgesia into two categories with different mortalities and obtained 9 variables that had the greatest impact on classification, which revealed that the depth of sedation was limited by the condition of the respiratory system.

Conducting clinical research on subjects admitted to intensive care units is challenging, as they frequently lack the capacity to provide informed consent due to multiple factors including intensive care unit acquired delirium, coma, the need for sedation, or underlying critical illness. However, the presence of one or more of these characteristics does not automatically designate a potential subject as lacking capacity to provide their own informed consent. We review the ethical issues involved in obtaining informed consent for medical research from mechanically ventilated, critically ill patients, in addition to the concerns that may arise when a legally authorized representative is asked to provide informed consent on behalf of these patients.

Objective: Increased gastric residual volume is a complication of enteral nutrition intolerance that leads to gastrointestinal complications such as nausea, vomiting, and aspiration pneumonia. The present study was conducted to determine the effect of gastric gas emptying on the residual gastric volume in mechanically-ventilated patients fed through nasogastric tubes.Methods: This randomized, single-blind, clinical trial was conducted on two groups of patients in the intensive care unit (ICU) of Kamyab Hospital of Mashhad. A total of 64 patients were randomly divided into a case and a control group. In the case group, the gastric gases accumulated through the nasogastric tube were emptied by applying palm pressure on the epigastric region. The control group did not undergo this intervention but received the routine care provided in the ward. Data were collected using a demographic questionnaire and a form containing records of the patients’ residual gastric volume and disease-related information. The residual gastric volume was measured and compared in the two groups before and after the intervention. Data were analyzed in SPSS-19 using the Chi-square test, the independent t-test, and the repeated measures ANOVA at the significance level of 5%.Results: The residual gastric volume did not differ significantly between the two groups before the intervention (p=0.14); after the intervention; however, a significant reduction was observed in the case group compared to the controls (p=0.007).Conclusion: Gastric gas emptying helps reduce the residual gastric volume in mechanically-ventilated patients fed through nasogastric tubes. Further studies are recommended to further ensure the benefits of this method.

Mechanical ventilation is widely used to treat patients with critical conditions. This treatment is usually applied for difficulty in breathing. The use of mechanical ventilation devices has unique benefits to the patient. However, it can also cause various problems. Reduction in communication rank as one of the most negative experiences in mechanically ventilated patients. Effective communication with ventilator-based patients is essential. Nursing management of a mechanically ventilated patient is challenging on many levels, requiring a wealth of high technical skills. The Patient Communications Board improves communication, maintains information and creates a comfortable, attractive setting for patient, family and health care workers. The research methodology used for the study is a Quasi experimental approach, post-test only design with a comparison group to assess the effect of the communication board on the level of satisfaction over communication among clients on mechanical ventilator. The sample was selected by purposive sampling technique and included 30 (experimental group-15, control group-15), mechanically ventilated patients in PESIMR hospital, Kuppam. The control group patients were provided with routine communication methods, while the experimental group were communicated with communication board. The level of satisfaction on communication was assessed by a 15items rating scale. Data was analysed using both the descriptive and inferential statistics. There was a significant difference in the level of satisfaction on communication among the patients who were communicated using communication board compared to the routine method of communication. The communication board had significantly improved the communication pattern and increased the satisfaction among the patients who are mechanically ventilated.

Background: Sleep disruptions frequently occur in hospitalized patients, especially with critically ill, mechanically ventilated patients. Severely altered sleep architectures result in unclassifiable sleep stages as listed by the conventional Rechtschaffen and Kales (R&K) criteria, and a new classification for sleep scoring including atypical sleep (AS) and pathological wakefulness (PW) has recently been proposed. Objective: To demonstrate the feasibility of performing objective sleep qualification in patients receiving mechanical ventilation due to acute respiratory failure. Materials and Methods: In the present prospective cohort study, polysomnography was performed in 38 patients requiring invasive mechanical ventilation due to acute respiratory failure at the respiratory care unit (RCU) of Siriraj Hospital between February and December 2017. Their sleep stages were analyzed by conventional rules and the new classifications of AS and PW. The associations between the presence of AS or PW and the patients’ characteristics were analyzed. Correlations between sleep quality and clinical parameters were also determined. Results: Most of the patients had poor sleep quality with median sleep efficiency (IQR) of 35.9% (18.5, 62.3) and significantly decreased slowwave sleep [median (IQR) 0.4% (0.00, 5.70)] and REM [median (IQR) 1.3% (0.00, 6.43)]. According to the new classifications, 14 out of 38 (prevalence of 36.8%) mechanically ventilated patients had AS. The prevalence of PW and either AS or PW were 36.8% and 52.6%, respectively. A higher baseline respiratory rate was observed among patients who had either AS or PW at 24 versus 20 breaths/minute (p=0.02), while a longer duration of mechanical ventilator support was found in patients with PW at nine versus five (p=0.003). Patient-ventilator asynchrony was also noted in all patients. Conclusion: Sleep quality among critically ill and mechanically ventilated patients was severely disturbed. A higher prevalence of AS and PW were noted. The technical feasibility of sleep recording in Thai intensive care unit (ICU) settings was established. Keywords: Polysomnography, Atypical sleep, ICU
