Ventilatory Management

Community-acquired pneumonia (CAP) is a leading cause of mortality worldwide. CAP mortality is driven by the development of sepsis and acute respiratory failure (ARF). We performed a systematic review of the available English literature published in the period 1 January 1997 to 31 August 2017 and focused on ARF in CAP. The database searches identified 189 articles—of these, only 29 were retained for data extraction. Of these 29 articles, 12 addressed ARF in CAP without discussing its ventilatory management, while 17 evaluated the ventilatory management of ARF in CAP. In the studies assessing the ventilatory management, the specific treatments addressed were: high-flow nasal cannula (HFNC) (n = 1), continuous positive airway pressure (n = 2), non-invasive ventilation (n = 9), and invasive mechanical ventilation (n = 5). When analyzed, non-invasive ventilation (NIV) success rates ranged from 20% to 76% and they strongly predicted survival, while NIV failure led to an increased risk of adverse outcome. In conclusion, ARF in CAP patients may require both ventilatory and non-ventilatory management. Further research is needed to better evaluate the use of NIV and HFNC in those patients. Alongside the prompt administration of antimicrobials, the potential use of steroids and the implementation of severity scores should also be considered.

BackgroundAlthough small randomised controlled trials (RCTs) and observational studies have examined helmet non-invasive ventilation (NIV), uncertainty remains regarding its role. We conducted a systematic review and meta-analysis to examine the effect of helmet NIV compared to facemask NIV or high flow nasal cannula (HFNC) in acute respiratory failure.MethodsWe searched multiple databases to identify RCTs and observational studies reporting on at least one of mortality, intubation, ICU length of stay, NIV duration, complications, or comfort with NIV therapy. We assessed study risk of bias (ROB) using the Cochrane ROB tool for RCTs and the Ottawa-Newcastle scale for observational studies and rated certainty of pooled evidence using GRADE.ResultsWe separately pooled data from 16 RCTs (n=949) and 8 observational studies (n=396). Compared to facemask NIV, based on low certainty evidence, helmet NIV may reduce mortality (relative risk (RR) 0.56, 95% confidence interval (CI) (0.33 to 0.95)), and intubation (RR 0.35, 95% CI (0.22 to 0.56)) in both hypoxic and hypercapnic respiratory failure but may have no effect on duration of NIV. There was an uncertain effect of helmet on ICU length of stay and development of pressure sores. Data from observational studies was consistent with the foregoing findings but of lower certainty. Based on low and very low certainty data, helmet NIV may reduce intubation compared to HFNC, but its effect on mortality is uncertain.ConclusionCompared to facemask NIV, helmet NIV may reduce mortality and intubation; however, the effect of helmet compared to HFNC remains uncertain.

Abstract BackgroundAcute Type 2 respiratory failure (AT2RF) is defined by hypercapnia (>6kPa) and these patients require ventilatory support in a significant proportion of cases. Non-invasive ventilation (NIV) is effective in preventing escalation to invasive mechanical ventilation (IMV) but has a high failure rate. High flow nasal oxygen (HFNO) is a novel device that integrates humidified air with oxygen at flow rates of up to 60 L/min. Various additional benefits including carbon-di-oxide (CO2) clearance have been attributed to HFNO. This systematic review aims to determine whether the use of HFNO for patients with AT2RF 1) improves arterial CO2 (PaCO2), 2) improves other clinical and patient-centred outcomes and 3) assess any potential harms.MethodSearches for relevant studies will be conducted in MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials, with no language restrictions. In addition, we will search Google Scholar and the references of all articles for any pertinent studies not found in our initial search. With the assistance of a professional librarian, we will develop a systematic search strategy using appropriate keywords and MeSH terms. We will identify trials that examined the efficacy of HFNO in adult AT2RF patients. We will include randomised trials and observational studies that compared two or more modalities of oxygen delivery that includes high flow nasal oxygen as one of the modes with the comparator being low flow oxygen and/or non-invasive ventilation. The primary outcome is change in PaCO2 level while other clinical and patient centred outcomes will be collected. Two reviewers will independently assess studies for eligibility, data extraction and quality appraisal. We will conduct a meta-analysis and/or a narrative summary as appropriate.DiscussionHFNO is utilised extensively in clinical practice with widening indications of use. The effects of HFNO includes CO2 clearance and PEEP benefits that may be beneficial to patients with AT2RF. While current publications indicate a beneficial role, no systematic review has attempted to summarise the evidence for this indication. The results of the proposed systematic review will summarise the current evidence to guide practice, guideline development and the design of future trials.Systematic review registrationPROSPERO CRD42019148748.
