BackgroundPatients who require positive pressure ventilation through a tracheostomy are unable to phonate due to the inflated tracheostomy cuff. Whilst a speaking valve (SV) can be used on a tracheostomy tube, its use in ventilated ICU patients has been inhibited by concerns regarding potential deleterious effects to recovering lungs. The objective of this study was to assess end expiratory lung impedance (EELI) and standard bedside respiratory parameters before, during and after SV use in tracheostomised patients weaning from mechanical ventilation.MethodsA prospective observational study was conducted in a cardio-thoracic adult ICU. 20 consecutive tracheostomised patients weaning from mechanical ventilation and using a SV were recruited. Electrical Impedance Tomography (EIT) was used to monitor patients’ EELI. Changes in lung impedance and standard bedside respiratory data were analysed pre, during and post SV use.ResultsUse of in-line SVs resulted in significant increase of EELI. This effect grew and was maintained for at least 15 minutes after removal of the SV (p < 0.001). EtCO2 showed a significant drop during SV use (p = 0.01) whilst SpO2 remained unchanged. Respiratory rate (RR (breaths per minute)) decreased whilst the SV was in situ (p <0.001), and heart rate (HR (beats per minute)) was unchanged. All results were similar regardless of the patients’ respiratory requirements at time of recruitment.ConclusionsIn this cohort of critically ill ventilated patients, SVs did not cause derecruitment of the lungs when used in the ventilator weaning period. Deflating the tracheostomy cuff and restoring the airflow via the upper airway with a one-way valve may facilitate lung recruitment during and after SV use, as indicated by increased EELI.Trial registrationAnna-Liisa Sutt, Australian New Zealand Clinical Trials Registry (ANZCTR).

Objective To identify core practices for workforce management of communication and swallowing functions in COVID-19 positive patients within the ICU. Design A modified Delphi methodology was utilized, with 3 electronic voting rounds. AGREE II and an adapted COVID-19 survey framework from physiotherapy were used to develop survey statements. Sixty-six statements pertaining to workforce planning and management of communication and swallowing function in the ICU were included. Setting Electronic modified Delphi process. Participants 35 speech-language pathologists (SLPs) from 6 continents representing 12 countries. Interventions Not applicable. Main Outcome Measures The main outcome was consensus agreement, defined a priori as ≥70% of participants with a mean Likert score ≥7.0 (11-point scale: “0” = strongly disagree, “10” strongly agree). Prioritization rank order of statements in a 4 th round was also conducted. Results SLPs with a median of 15 years ICU experience, working primarily in clinical (54%), in academic (29%) or managerial (17%) positions, completed all voting rounds. After the third round, 64 statements (97%) met criteria. Rank ordering identified issues of high importance. Conclusions A set of global consensus statements to facilitate planning and delivery of rehabilitative care for patients admitted to the ICU during the COVID-19 pandemic were agreed by an international expert SLP group. Statements focus on considerations for workforce preparation, resourcing and training, and the management of communication and swallowing functions. These statements support and provide direction for all members of the rehabilitation team to use for patients admitted to the ICU during a global pandemic.

Objective. To assess the effects of neurostimulation (i.e., neuromuscular electrical stimulation (NMES) and pharyngeal electrical stimulation (PES)) in people with oropharyngeal dysphagia (OD). Methods. Systematic literature searches were conducted to retrieve randomised controlled trials in four electronic databases (CINAHL, Embase, PsycINFO, and PubMed). The methodological quality of included studies was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2). Results. In total, 42 studies reporting on peripheral neurostimulation were included: 30 studies on NMES, eight studies on PES, and four studies on combined neurostimulation interventions. When conducting meta analyses, significant, large and significant, moderate pre-post treatment effects were found for NMES (11 studies) and PES (five studies), respectively. Between-group analyses showed small effect sizes in favour of NMES, but no significant effects for PES. Conclusion. NMES may have more promising effects compared to PES. However, NMES studies showed high heterogeneity in protocols and experimental variables, the presence of potential moderators, and inconsistent reporting of methodology. Therefore, only conservative generalisations and interpretation of meta-analyses could be made. To facilitate comparisons of studies and determine intervention effects, there is a need for more randomised controlled trials with larger population sizes, and greater standardisation of protocols and guidelines for reporting.

Communication difficulties and their effects on patients who are mechanically ventilated are commonly reported and well described. The possibility of restoring speech for patients has obvious benefits, not only for meeting patient’s immediate needs, but for helping them to re-engage in relationships and participate meaningfully in their recovery and rehabilitation. This opinion piece by a group of United Kingdom (UK) based Speech and Language Therapy experts working in critical care describes the various ways by which a patient’s own voice can be restored. Common barriers to using different techniques and potential solutions are explored. We therefore hope that this will encourage intensive care unit (ICU) multi-disciplinary teams to advocate and facilitate early verbal communication in these patients.

Objective: To determine the effects of behavioural interventions in people with oropharyngeal dysphagia. Methods: Systematic literature searches were conducted to retrieve randomized controlled trials in four different databases (CINAHL, Embase, PsycINFO, and PubMed). The methodological quality of eligible articles was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2), after which meta-analyses were performed using a random-effects model. Results: A total of 37 studies were included. Overall, a significant, large pre-post interventions effect size was found. To compare different types of interventions, all behavioural interventions and conventional dysphagia treatment comparison groups were categorised into compensatory, rehabilitative, and combined compensatory and rehabilitative interventions. Overall, significant treatment effects were identified favouring behavioural interventions. In particular, large effect sizes were found when comparing rehabilitative interventions with no dysphagia treatment, and combined interventions with compensatory conventional dysphagia treatment. When comparing selected interventions versus conventional dysphagia treatment, significant, large effect sizes were found in favour of Shaker exercise, chin tuck against resistance exercise, and expiratory muscle strength training. Conclusions: Behavioural interventions show promising effects in people with oropharyngeal dysphagia. However, due to high heterogeneity between studies, generalisations of meta-analyses need to be interpreted with care.

Purpose: Patients supported with extracorporeal membrane oxygenation (ECMO) have been reported to have increased sedation requirements. Tracheostomies are performed in intensive care to facilitate longer term mechanical ventilation, reduce sedation, improve patient comfort, secretion clearance, and ability to speak and swallow. We aimed to investigate the safety of tracheostomy (TT) placement on ECMO, its impact on fluid intake, and the use of sedative, analgesic, and vasoactive drugs. Methods: Prospective data were collated for all ECMO patients over a 5.5-year period. Data included the cumulative dose of sedatives and analgesics, fluid balance, inotrope and vasopressor requirements, and number of packed red cell (PRC) units transfused. Data were analyzed to determine the differences in the aforementioned between 5 days pre-TT and post-TT insertion. Results: Thirty-one (22.1%) of 140 patients underwent TT while on ECMO in the study period. Inotrope and vasopressor use was significantly less in the post-TT period compared to pre-TT dose (P value ¼ .01). This was in the setting of Sequential Organ Failure Assessment scores the day before TT placement being significantly greater than those on days 2, 3, and 4. There was a trend toward reduction in analgesic usage in the post-TT period. No major complications of TT were reported. There was no significant difference (P value ¼ .46) in the amount of PRC used post-TT. Conclusions: These data indicate that TT may result in a reduction in vasopressor and inotropic requirement. Data do not suggest increased major bleeding with placement of TT in patients on ECMO. The potential risk and benefits of inserting a TT in ECMO patients need further validation in prospective clinical studies.
