Impact of a multidisciplinary checklist on the duration of invasive mechanical ventilation and length of ICU stay

AbstractObjectiveThe aim of the present study was to explore and compare the association between a new vasoactive score – the Total Inotrope Exposure Score – and outcome and the established Vasoactive Inotrope Score in children undergoing cardiac surgery with cardiopulmonary bypassDesignThe present study was a single-centre, retrospective study.SettingThe study was carried out at a 21-bed cardiovascular ICU in a Tertiary Children’s Hospital between September, 2010 and May, 2011MethodsThe Total Inotrope Exposure Score is a new vasoactive score that brings together cumulative vasoactive drug exposure and incorporates dose adjustments over time. The performance of these scores – average, maximum Vasoactive Inotrope Score at 24 and 48 hours, and Total Inotrope Exposure Score – to predict primary clinical outcomes – either death, cardiopulmonary resuscitation, or extra-corporeal membrane oxygenation before hospital discharge – and secondary outcomes – length of invasive mechanical ventilation, length of ICU stay, and hospital stay – was calculated.Main resultsThe study cohort included 167 children under 18 years of age, with 37 (22.2%) neonates and 65 (41.3%) infants aged between 1 month and 1 year. The Total Inotrope Exposure Score best predicted the primary outcome (six of 167 cases) with an unadjusted odds ratio for a poor outcome of 42 (4.8, 369.6). Although the area under curve was higher than other scores, this difference did not reach statistical significance. The Total Inotrope Exposure Score best predicted prolonged invasive mechanical ventilation, length of ICU stay, and hospital stay as compared with the other scores.ConclusionThe Total Inotrope Exposure Score appears to have a good association with poor postoperative outcomes and warrants prospective validation across larger numbers of patients across institutions.

Abstract Background The efficacy of high flow nasal canula oxygen therapy (HFNO) to prevent invasive mechanical ventilation (IMV) is not well established in severe coronavirus disease 2019 (COVID-19). The aim of this study was to compare the risk of IMV between two strategies of oxygenation (conventional oxygenation and HFNO) in critically ill COVID 19 patients. Methods This was a bicenter retrospective study which took place in two intensive care units (ICU) of tertiary hospitals in the Paris region from March 11, to May 3, 2020. We enrolled consecutive patients hospitalized for COVID-19 and acute respiratory failure (ARF) who did not receive IMV at ICU admission. The primary outcome was the rate of IMV after ICU admission. Secondary outcomes were death at day 28 and day 60, length of ICU stay and ventilator-free days at day 28. Data from the HFNO group were compared with those from the standard oxygen therapy (SOT) group using weighted propensity score. Results Among 138 patients who met the inclusion criteria, 62 (45%) were treated with SOT alone, and 76 (55%) with HFNO. In HFNO group, 39/76 (51%) patients received IMV and 46/62 (74%) in SOT group (OR 0.37 [95% CI, 0.18–0.76] p = 0.007). After weighted propensity score, HFNO was still associated with a lower rate of IMV (OR 0.31 [95% CI, 0.14–0.66] p = 0.002). Length of ICU stay and mortality at day 28 and day 60 did not significantly differ between HFNO and SOT groups after weighted propensity score. Ventilator-free days at days 28 was higher in HNFO group (21 days vs 10 days, p = 0.005). In the HFNO group, predictive factors associated with IMV were SAPS2 score (OR 1.13 [95%CI, 1.06–1.20] p = 0.0002) and ROX index > 4.88 (OR 0.23 [95%CI, 0.008–0.64] p = 0.006). Conclusions High flow nasal canula oxygen for ARF due to COVID-19 is associated with a lower rate of invasive mechanical ventilation.

Length Of Icu Stay

A number of controlled trials have previously found that in some contexts, vitamin C can have beneficial effects on blood pressure, infections, bronchoconstriction, atrial fibrillation, and acute kidney injury. However, the practical significance of these effects is not clear. The purpose of this meta-analysis was to evaluate whether vitamin C has an effect on the practical outcomes: length of stay in the intensive care unit (ICU) and duration of mechanical ventilation. We identified 18 relevant controlled trials with a total of 2004 patients, 13 of which investigated patients undergoing elective cardiac surgery. We carried out the meta-analysis using the inverse variance, fixed effect options, using the ratio of means scale. In 12 trials with 1766 patients, vitamin C reduced the length of ICU stay on average by 7.8% (95% CI: 4.2% to 11.2%; p = 0.00003). In six trials, orally administered vitamin C in doses of 1–3 g/day (weighted mean 2.0 g/day) reduced the length of ICU stay by 8.6% (p = 0.003). In three trials in which patients needed mechanical ventilation for over 24 hours, vitamin C shortened the duration of mechanical ventilation by 18.2% (95% CI 7.7% to 27%; p = 0.001). Given the insignificant cost of vitamin C, even an 8% reduction in ICU stay is worth exploring. The effects of vitamin C on ICU patients should be investigated in more detail.

Abstract Background. Some patients who had previously presented with COVID-19 have been reported to develop persistent COVID-19 symptoms. Whilst this information has been adequately recognised and extensively published with respect to non-critically ill patients, less is known about the prevalence and risk factors and characteristics of persistent COVID_19 . On other hand these patients have very often intensive care unit-acquired pneumonia (ICUAP). A second infectious hit after COVID increases the length of ICU stay and mechanical ventilation and could have an influence in the poor health post-Covid 19 syndrome in ICU discharged patientsMethods: This prospective, multicentre and observational study was done across 40 selected ICUs in Spain. Consecutive patients with COVID-19 requiring ICU admission were recruited and evaluated three months after hospital discharge. Results: A total of 1,255 ICU patients were scheduled to be followed up at 3 months; however, the final cohort comprised 991 (78.9%) patients. A total of 315 patients developed ICUAP (97% of them had ventilated ICUAP) Patients requiring invasive mechanical ventilation had persistent, post-COVID-19 symptoms than those who did not require mechanical ventilation. Female sex, duration of ICU stay, and development of ICUAP were independent risk factors for persistent poor health post-COVID-19.Conclusions: Persistent, post-COVID-19 symptoms occurred in more than two-thirds of patients. Female sex, duration of ICU stay and the onset of ICUAP comprised all independent risk factors for persistent poor health post-COVID-19. Prevention of ICUAP could have beneficial effects in poor health post-Covid 19

Abstract Background: In late December 2019, Covid-19 emerged as clusters of pneumonia of unknown cause in a province of china, Wuhan. Etiological agent was identified as novel coronavirus that resembles severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East Respiratory syndrome coronavirus (MERS-CoV) and has zoonotic transmission. Covid pneumonia can remain asymptomatic, present as mild infection, severe pneumonia or respiratory failure. Diagnosis is based on rRT-PCR carried out on respiratory secretions. Covid related mortality exceeds 50% once patient requires ICU admission. Objective: To study the characteristics of ICU population admitted to ICU of Shifa International hospital.Results: we prospectively analysed 74 patients which included 43.3% females and 56.7% males. Commonest symptoms were shortness of breath (94.5%), fever (74.3%) and cough (74.3%). Most of our study population consisted of non-smokers (79.7%) and had hypertension (59.4%) followed by diabetes (47.2%). Hydroxychloroquine (HCQ) and azithromycin combination is superior to hydroxychloroquine and doxycycline in reducing mortality (p=0.023) whereas Doxycycline alone resulted in increased mortality (p=0.009). Those who did not require antibiotics or required only narrow spectrum antibiotics had increased survival and reduced requirement of invasive mechanical ventilation (p=< 0.0001). in our study population, (44.9%) developed acute kidney injury, 2.7% needed re-intubations 10.8% developed surgical emphysema and 2.7 % thromboembolic events despite full anticoagulation. ICU mortality was 41.8% and was higher in females (59.4%, p=0.008), those who had SOFA score > 3.5 at time of admission, raised D-Dimers > 931 ng/ml, NLR > 9.2. It was further high in those who required invasive mechanical ventilation and vasopressor support (58.1% mortality p=< 0.001). ICU stay was more prolonged in those requiring invasive mechanical ventilation as compared to those who did not. (23 days vs 6 days, p=0.001). Mean plateau pressure was 19.6 ± 7.6; mean Driving pressures 14.4 ± 4.6; mean PaO2/FiO2 150.7 ± 73.9; mean SPO2/FiO2 173.9 ± 106.9; mean PEEP was 8.2 ±4.33.Conclusion: We concluded that severe covid pneumonia is common amongst males, non-smokers those who had comorbid. HCQ and azithromycin combination is superior to combination of HCQ and doxycycline or doxycycline alone and QT prolongation is a rare complication. Baseline NLR, APACHI II, SOFA, SAPS II, NUTRIC scores, D-Dimers, invasive ventilation and vasopressor support are important tools to predict ICU mortality. Invasive mechanical ventilation carries higher mortality and associated with more prolonged ICU stay. AKI is most common complication followed by shock and surgical emphysema. CRP, Ferritin levels has no impact on outcome.

Abstract Introduction Ventilator-associated pneumonia (VAP) is reported as the second most common nosocomial infection among critically ill patients with the incidence ranging from 2 to 16 episodes per 1000 ventilator days. The use of probiotics has been shown to have a promising effect in many RCTs. Our systematic review and meta-analysis were thus planned to determine the effect of probiotic use in critically ill ventilated adult patients on the incidence of VAP, length of hospital stay, length of ICU stay, duration of mechanical ventilation, the incidence of diarrhea, and the incidence of oropharyngeal colonization and in-hospital mortality. Methodology Systematic search of various databases (such as Embase, Cochrane, and Pubmed), published journals, clinical trials, and abstracts of the various major conferences were made to obtain the RCTs which compare probiotics with placebo for VAP prevention. The results were expressed as risk ratios or mean differences. Data synthesis was done using statistical software - Review Manager (RevMan) Version 5.4 (The Cochrane Collaboration, 2020). Results Nine studies met our inclusion criterion and were included in the meta-analysis. The incidence of VAP (risk ratio: 0.70, CI 0.56, 0.88; P = 0.002; I2 = 37%), duration of mechanical ventilation (mean difference −3.75, CI −6.93, −0.58; P 0.02; I2 = 96%), length of ICU stay (mean difference −4.20, CI −6.73, −1.66; P = 0.001; I2 = 84%) and in-hospital mortality (OR 0.73, CI 0.54, 0.98; P = 0.04; I2 = 0%) in the probiotic group was significantly lower than that in the control group. Probiotic administration was not associated with a statistically significant reduction in length of hospital stay (MD −1.94, CI −7.17, 3.28; P = 0.47; I2 = 88%), incidence of oro-pharyngeal colonization (OR 0.59, CI 0.33, 1.04; P = 0.07; I2 = 69%), and incidence of diarrhea (OR 0.59, CI 0.34, 1.03; P = 0.06; I2 = 38%). Discussion Our meta-analysis shows that probiotic administration has a promising role in lowering the incidence of VAP, the duration of mechanical ventilation, length of ICU stay, and in-hospital mortality.

Objective: To evaluate whether the off-hours admission has any effect on risk-adjusted mortality and length of stay for nonelective patients admitted to a pediatric intensive care unit (PICU) without 24-hour in-house intensivist coverage. Design: Prospective cohort study. Setting: A 34-bed tertiary PICU. Patients: All consecutive nonelective patients aged 0 to 14 years admitted from January 2012 to June 2015. Measurements and Main Results: A total of 1254 patients were nonelectively admitted to the PICU. They were categorized according to time of PICU admission as either office hours (07:30 to 16:30 from Sunday to Thursday and whenever an intensivist is present in the ICU) or off-hours (16:30 to 07:30, Friday and Saturday and public holidays). Standardized mortality rates (SMRs) of patients admitted during off-hours were compared to SMRs of patients admitted during office hours using Pediatric Risk of Mortality (PRISM2) score. Multivariate logistic regression was used to assess the effect of time of admission on outcome after adjustment for severity of illness using the PRISM2. The mortality observed in the office-hours group was 9.4% and in the off-hours group was 8.1%. The PRISM2-based SMR was 0.83 (95% confidence interval [CI]: 0.43-1.47) for the office-hours group and 0.68 (95% CI: 0.34-1.36) for the off-hours group. No significant differences in length of ICU stay or duration of mechanical ventilation were observed between patients admitted during off-hours and those admitted during office hours. In the logistic regression model, off-hours admission was not significantly associated with a higher mortality (odds ratio: 0.85, 95% CI: 0.57-1.27; P = .44). Conclusions: The absence of an in-house intensivist during off-hours is not associated with an increase in mortality, length of ICU stay, or duration of mechanical ventilation for patients admitted to our pediatric ICU.

Abstract Background Invasive mechanical ventilation (IMV) for management of chronic obstructive pulmonary disease (COPD) associated respiratory failure is increasing in Intensive Care Units. The bridging process from IMV to extubation is called weaning in which mechanical ventilation is gradually withdrawn and the patient resumes spontaneous breathing. Many objective parameters have been defined for weaning success. The following review focuses on the different weaning methods in patients chronic obstructive pulmonary disease with respiratory failure. Objective To compare among the different methods of weaning in chronic obstructive pulmonary disease patients with respiratory failure weaned with different method ie BIPAP, CPAP and T-Piece. Patients and Methods Cross sectional descriptive study. 60 patients diagnosed as COPD with respiratory failure on MV, will be recruited from ICU Department Zefta general hospital. This study included 60 patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) with age more than18 years old admitted in adult ICU Department in Zefta general hospital that are on mechanical ventilation. These patients fulfilled the inclusion criteria of the study. Patients were classified randomly into 3 groups. Results In this study I try to overcome these challenges by studying the effect of using of NIPPV both CPAP or BIPAP immediately after extubation or using T piece for 1 hour followed by extubation and using oxygen therapy that BIPAP improves patient gas exchange, hemodynamics and associated with shortest ICU stay which reflects on utilization of resources. Conclusion We suggest that BIPAP improves patient gas exchange specially in hypercapnic patients, hemodynamics and associated with shortest duration of ICU stay and decrease rate of reintuabtion.
