The Efficacy of the NHS Waterpipe in Superficial Hydration for People With Healthy Voices: Effects on Acoustic Voice Quality, Phonation Threshold Pressure and Subjective Sensations. J Voice 2024; 38:244.e29-244.e42. [PMID: 34702612 DOI: 10.1016/j.jvoice.2021.08.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 08/18/2021] [Accepted: 08/18/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES This study examined the efficacy of the NHS waterpipe as a superficial hydration treatment in voice production in healthy young women. STUDY DESIGN This is a prospective, single-blind, within- and between-subject experimental design. METHODS Thirty six female university students (mean age 24.6 years, range 19-45 years) were recruited to the study. Participants were randomized to two experimental groups (E1 and E2) and a control group. E1 underwent hydration treatment with the NHS waterpipe filled with 0.9% saline that was immersed in a cup of heated water. E2 underwent a similar treatment but without heated immersion. The control group received no treatment. Acoustic Voice Quality Index (AVQI v03.01) and its subparameters, phonation threshold pressure, self-perceived phonatory effort and sensation of throat dryness was measured at three time points (before the intervention and immediately and 15 minutes after it). RESULTS The Tilt of the AVQI's subparameters increased significantly in the E1 (P = 0.027) and E2 groups (P = 0.027) after the intervention. Furthermore, the E1 group had significantly lower harmonics-to-noise-ratio values at the third measurement point compared to the E2 group (P = 0.023). These findings may result from fluid transported to the vocal fold level. The sensations of throat dryness decreased in the E1 (P = 0.001) and E2 groups (P < 0.0005) after the intervention. Perceived phonatory effort decreased statistically significantly at the final measurement point in the E1 (P = 0.002) and E2 (P = 0.031) groups. No variables changed in the control group. CONCLUSIONS The waterpipe seems to be efficient in hydrating vocal folds on single use. It seems to be more efficient when employed with a hot water bath, albeit slightly impairing some acoustic values in the short term. Without the heated fluid, it still seems to decrease sensations of throat dryness and affect acoustic voice quality. The waterpipe does not seem to have an effect on phonation threshold pressure, and it seems to lower self-perceived effort just as efficiently whether the waterpipe is employed using a hot water bath or not. Further research is needed to prove the efficacy of long-term usage and usage with voice patients.

Abstract
OBJECTIVE Effective postoperative tracheostomy management after free flap surgery is critical but can offer challenges including difficulty with humidification delivery and contraindications toward neck instrumentation. The purpose of this project was to establish a multidisciplinary team and implement the AIRVO™ tracheostomy humidification system for those undergoing free flap surgery and determine its effect on respiratory secretions and related events. METHODS A retrospective cohort study of head and neck free flap surgery patients prior to implementation of AIRVO™ (Jan 2021-May 2021) and after (August 2021-December 2021) were analyzed with a 2 month (June 2021-July 2021) implementation phase. Main variables analyzed included excessive tracheal secretions, necessity of supplemental oxygen above baseline for a day or greater, respiratory rapid response calls, elevation to intensive care units (ICU), and length of hospital stay. RESULTS A total of 82 patients (40 pre-AIRVO™ and 42 with AIRVO™) met criteria for the study. A significant reduction in excessive tracheal secretions (40% pre-AIRVO™, 11.9% with AIRVO™, P = .01) and necessity of supplemental oxygen above baseline (25% pre-AIRVO™, 7.1% with AIRVO™, P = .04) were observed. No significant difference in hospital length of stay (P = .63) was observed. No respiratory rapid responses or elevation to ICU care were seen in either groups. CONCLUSION The AIRVO™ system provided an efficient, portable, free of neck instrumentation, and easy to use device that resulted in a reduction in excessive tracheal secretion events and necessity of supplemental oxygenation needs in free flap tracheostomy patients.

Acta Anaesthesiol Scand 2023; 67:1403-1413. [PMID: 37437910 DOI: 10.1111/aas.14305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 06/12/2023] [Accepted: 06/20/2023] [Indexed: 07/14/2023]
Abstract
BACKGROUND Weaning from mechanical ventilation and tracheostomy after prolonged intensive care consume enormous resources with optimal management not currently well described. Restoration of respiratory flow via the upper airway is essential and early cuff-deflation using a one-way valve (OWV) is recommended. However, extended OWV use may cause dry airways and thickened secretions which challenge the weaning process. High-flow therapy via the tracheostomy tube (HFT-T) humidifies inspired air and may be connected via an in-line OWV (HFT-T-OWV) alleviating these problems. We aim to provide clinical and experimental data on the safety of HFT-T-OWV along with a practical guide to facilitate clinical use during weaning from mechanical ventilation and tracheostomy. METHODS Data on adverse events of HFT-T-OWV were retrieved from a quality register for patients treated at an intensive care rehabilitation center between 2019 and 2022. Benchtop experiments were performed to measure maximum pressures and pressure support generated by HFT-T-OWV at 25-60 L/min flow using two different HFT-T adapters (interfaces). In simulated airway obstruction using a standard OWV (not in-line) maximum pressures were measured with oxygen delivered via the side port at 1-3 L/min. RESULTS Of 128 tracheostomized patients who underwent weaning attempts, 124 were treated with HFT-T-OWV. The therapy was well tolerated, and no adverse events related to the practice were detected. The main reason for not using HFT-T-OWV was partial upper airway obstruction using a OWV. Benchtop experiments demonstrated HFT-T-OWV maximum pressures <4 cmH2 O and pressure support 0-0.6 cmH2 O. In contrast, 1-3 L/min supplemental oxygen via a standard OWV caused pressures between 84 and 148 cmH2 O during simulated airway obstruction. CONCLUSIONS Current study clinical data and benchtop experiments indicate that HFT-T-OWV was well tolerated and appeared safe. Pressure support was low, but humidification may enable extended use of a OWV without dry airway mucosa and thickened secretions. Results suggest the treatment could offer advantages to standard OWV use, with or without supplementary oxygen, as well as to HFT-T without a OWV, for weaning from mechanical ventilation and tracheostomy. However, for definitive treatment recommendations, randomized clinical trials are needed.

Abstract
High-flow therapy (HFT) is the administration of gas flows above 15 L/min. It is a non-invasive respiratory support that delivers heated (up to 38 °C), humidified (100% Relative Humidity, RH; 44 mg H2O/L Absolute Humidity, AH), oxygen-enriched air when necessary, through a nasal cannula or a tracheostomy interface. Over the last few years, the use of HFT in critically ill hypoxemic adults has increased. Although the clinical benefit of home high-flow therapy (HHFT) remains unclear, some research findings would support the use of HHFT in chronic respiratory diseases. The aim of this review is to describe the HFT physiological principles and summarize the published clinical findings. Finally, we will discuss the differences between hospital and home implementation, as well as the various devices available for HHFT application.

Abstract
BACKGROUND Dexpanthenol-containing ointments/fluids are recommended to restore impaired nasal mucosa. To date, there are no data about the influence of dexpanthenol or formulations including dexpanthenol on ciliary beat frequency (CBF) of nasal epithelial cells. METHODS We tested the ciliary beat frequency of human nasal epithelial cells in RPMI 1640 cell solution using in vitro high-frequency video microscopy every 60 s over a period of 15 min (min). Bepanthen® solution and dexpanthenol in two clinically relevant concentrations (1.67% and 3.33%) were added to the cells. Addition of sterile water served as control group. To get a better overview, the measurements after 1 min, 5 min and 15 min were combined. RESULTS The CBF in the control group (n = 17) after 15 min was 7.3 ± 2.6 Hz. In comparison, the CBF after 15 min was 1.8 ± 1.0 Hz in the 3.33% Bepanthen® group (n = 17) and 3.2 ± 1.2 Hz in the 1.67% group, which was statistically significantly lower in both groups (p < 0.001). With regard to the dexpanthenol group (n = 17) a CBF of 6.0 ± 2.6 Hz with 3.33% and 6.1 ± 2.4 Hz with 1.67% dexpanthenol, was detected, which was again statistically significantly lower (p = 0.06) compared to the control group except CBF at 15 min with 1.57% (n = 17; p = 0.04). In general, the effect on CBF was less pronounced with dexpanthenol compared with Bepanthen® with a statistically significant difference between the two formulations. The results were verified by calculating an analysis of variance (ANOVA). CONCLUSIONS Bepanthen® as an ointment, solution or inhalation is commonly used in ENT for mucosal care. Our results have shown that both substances reduce CBF in clinically relevant concentrations, although the effect was more pronounced with Bepanthen® compared to dexpanthenol solution, which could be related to additives or change of physical properties in the solution. Further research is needed to assess potential clinical relevance.

Edwards DA, Chung KF. Mouth breathing, dry air, and low water permeation promote inflammation, and activate neural pathways, by osmotic stresses acting on airway lining mucus.

Abstract
Respiratory disease and breathing abnormalities worsen with dehydration of the upper airways. We find that humidification of inhaled air occurs by evaporation of water over mucus lining the upper airways in such a way as to deliver an osmotic force on mucus, displacing it towards the epithelium. This displacement thins the periciliary layer of water beneath mucus while thickening topical water that is partially condensed from humid air on exhalation. With the rapid mouth breathing of dry air, this condensation layer, not previously reported while common to transpiring hydrogels in nature, can deliver an osmotic compressive force of up to around 100 cm H2O on underlying cilia, promoting adenosine triphosphate secretion and activating neural pathways. We derive expressions for the evolution of the thickness of the condensation layer, and its impact on cough frequency, inflammatory marker secretion, cilia beat frequency and respiratory droplet generation. We compare our predictions with human clinical data from multiple published sources and highlight the damaging impact of mouth breathing, dry, dirty air and high minute volume on upper airway function. We predict the hypertonic (or hypotonic) saline mass required to reduce (or amplify) dysfunction by restoration (or deterioration) of the structure of ciliated and condensation water layers in the upper airways and compare these predictions with published human clinical data. Preserving water balance in the upper airways appears critical in light of contemporary respiratory health challenges posed by the breathing of dirty and dry air.

Abstract
BACKGROUND Tracheostomy is a common procedure in critical care. The aim of this study was to evaluate the application of a liposomal inhalation compared to standard physiologic saline (SPS) inhalation on basis of objective and subjective parameters of airway inflammation. METHODS We evaluated in this two-armed, double-blinded and randomized control group study the effect of liposomal compared with SPS inhalation in newly tracheotomized patients. The primary endpoint was defined as trend of tracheobronchial IL-6 secretion at day 1 compared to day 10. Further objective and subjective parameter were evaluated. RESULTS Fifty patients were randomized in each arm. Tracheal IL-6 levels decreased significantly only after liposomal inhalation. Both inhalative agents seem to have an effect on the respiratory impairment after tracheostomy. Subjective patient impairment was reduced significantly from day 1 to day 10 after tracheostomy with liposomal inhalation. CONCLUSIONS Liposomal inhalation demonstrated an advantage over SPS inhalation in newly tracheotomized patients.

Rapid changes in mucociliary transport in the tracheal epithelium caused by unconditioned room air or nebulized hypertonic saline and mannitol are not determined by frequency of beating cilia. Intensive Care Med Exp 2021; 9:8.

Abstract
Background Inspired air is heated and humidified in the nose before it reaches lower airways. This mechanism is bypassed during tracheostomy, directly exposing the airways to colder and drier air from the environment, known to negatively affect mucociliary transport; however, little is known about how quickly mucociliary transport deteriorates. This study determines the short-term effect of flowing room air and nebulized hypertonic saline and mannitol on mucociliary transport in the trachea. In an ovine perfused in vitro tracheal model (N = 9) the epithelium was exposed to 25 L/min of flow, heated to lamb body temperature (38 °C) and fully saturated with water vapor as the control, followed by either room air (22 °C and 50% relative humidity) or nebulized solutions of NaCl 7% and mannitol 20% up to 1 min for a short duration, until mucociliary transport had visually changed. Mucus transport velocity (MTV) and cilia beat frequency (CBF) were continuously measured with video-microscopy. Results Exposing the tracheal epithelium to air heated to body temperature and fully humidified had stable MTV 9.5 ± 1.1 mm/min and CBF 13.4 ± 0.6 Hz. When exposed to flow of room air, MTV slowed down to 0.1 ± 0.1 mm/min in 2.0 ± 0.4 s followed by a decrease in CBF to 6.7 ± 1.9 Hz, after 2.3 ± 0.8 s. Both MTV and CBF recovered to their initial state when heated and humidified air-flow was re-introduced. Exposing the tracheal epithelium to nebulized hypertonic saline and nebulized mannitol for 1 min increased MTV without a subsequent increase in CBF. Conclusions This study demonstrates mucociliary transport can deteriorate within seconds of exposing the tracheal epithelium to flowing room air and increase rapidly when exposed to nebulized hypertonic solutions. The reduction in MTV precedes slowing of CBF with room air and MTV increases without a subsequent increase in CBF during the nebulization. Their relationship is non-linear and a minimum CBF of approximately 6 Hz is required for MTV > 0, while MTV can reach 10.9 mm/min without CBF increasing. Clinically these findings indicate a potential rapid detrimental effect of breathing with non-humidified air via bypassed upper airways and the short-term effects of nebulized osmotic agents that increase MTV.

Abstract
BACKGROUND When patients with a tracheostomy tube reach a stage in their care at which decannulation appears to be possible, it is common practice to cap the tracheostomy tube for 24 hours to see whether they can breathe on their own. Whether this approach to establishing patient readiness for decannulation leads to better outcomes than one based on the frequency of airway suctioning is unclear. METHODS In five intensive care units (ICUs), we enrolled conscious, critically ill adults who had a tracheostomy tube; patients were eligible after weaning from mechanical ventilation. In this unblinded trial, patients were randomly assigned either to undergo a 24-hour capping trial plus intermittent high-flow oxygen therapy (control group) or to receive continuous high-flow oxygen therapy with frequency of suctioning being the indicator of readiness for decannulation (intervention group). The primary outcome was the time to decannulation, compared by means of the log-rank test. Secondary outcomes included decannulation failure, weaning failure, respiratory infections, sepsis, multiorgan failure, durations of stay in the ICU and hospital, and deaths in the ICU and hospital. RESULTS The trial included 330 patients; the mean (±SD) age of the patients was 58.3±15.1 years, and 68.2% of the patients were men. A total of 161 patients were assigned to the control group and 169 to the intervention group. The time to decannulation was shorter in the intervention group than in the control group (median, 6 days [interquartile range, 5 to 7] vs. 13 days [interquartile range, 11 to 14]; absolute difference, 7 days [95% confidence interval, 5 to 9]). The incidence of pneumonia and tracheobronchitis was lower, and the duration of stay in the hospital shorter, in the intervention group than in the control group. Other secondary outcomes were similar in the two groups. CONCLUSIONS Basing the decision to decannulate on suctioning frequency plus continuous high-flow oxygen therapy rather than on 24-hour capping trials plus intermittent high-flow oxygen therapy reduced the time to decannulation, with no evidence of a between-group difference in the incidence of decannulation failure.

Abstract
Background: High-flow oxygen therapy (HFOT) is increasingly used for acute respiratory
failure. Few data support its use at home for the treatment of chronic
respiratory failure. Our aim was to report the pattern of the use of
long-term HFOT in our center and the outcome of patients setup on long-term
HFOT. Methods: A retrospective monocentric study including all patients setup on long-term
HFOT between January 2011 and April 2018 in Rouen University Hospital was
carried out. Patients were divided into two groups, patients with hypoxemic
respiratory failure treated with nasal HFOT (nHFOT) and tracheotomized
patients treated with tracheal HFOT (tHFOT). Results: A total of 71 patients were established on long-term HFOT. Out of these 43
(61%) were included in the nHFOT group and 28 (39%) were included in the
tHFOT group. In the nHFOT group, underlying respiratory diseases were
interstitial lung disease (n = 15, 35%), pulmonary
hypertension (n = 12, 28%), lung cancer
(n = 9, 21%), and chronic airway disease
(n = 7, 16%). In the tHFOT group, the number of
admissions for exacerbation decreased by −0.78 per year (–2 to 0)
(p = 0.045). In total, 51 (72%) patients were
discharged to their homes and 20 (28%) went to a post-acute re-enablement
facility. Median survival following HFOT was 7.5 months. Survival was
significantly lower in the nHFOT group with a median survival of 3.6 months
whereas median survival was not reached in the tHFOT group
(p < 0.001). Monthly costs associated with home
delivery of HFOT were €476 (296–533) with significant differences in costs
between the nHFOT group of €520 (408–628) and costs in the tHFOT group of
€296 (261–475) (p < 0.001). Conclusions: The use of long-term HFOT allows very severe patients to be discharged at a
reasonable cost from acute care facilities. The reviews of this paper are available via the supplementary
material section.

Head Neck 2017; 39:2481-2487.

Abstract
Background After tracheostomy, the airway lacks an essential mechanism for warming and humidifying the inspired air with the consequent functional impairment and discomfort. The purpose of this study was to compare airway hydration with cold‐air nebulization versus heated high‐flow humidification on medical interventions and tracheal ciliary beat frequency (CBF). Methods Newly tracheostomized patients (n = 20) were treated either with cold‐air nebulization or heated humidification. The number of required tracheal suctioning procedures to clean the trachea and tracheal CBF were assessed. Results The number of required suctions per day was significantly lower in the heated humidification group with medians 3 versus 5 times per day. Mean CBF was significantly higher in the heated humidification group (6.36 ± 1.49 Hz) compared to the cold‐air nebulization group (3.99 ± 1.39 Hz). Conclusion The data suggest that heated humidification enhanced mucociliary transport leading to a reduced number of required suctioning procedures in the trachea, which may improve postoperative patient care.
