Suctioning is not a benign procedure. Intrapulmonary percussive ventilation is intriguing; I think it does that by using fairly large volumes. According to the American Association for Respiratory Care's 2005 Uniform Reporting Manual, the time standard (referenced here as mode) for airway clearance is 1520 min per session. Risk of aspiration. Relaxing airway smooth muscle with bronchodilation may reduce the effectiveness of airway peristalsis for mucus propulsion. The problem with all these secretion-clearance studies is that they consider percussion and postural drainage the accepted standard when there's no evidence that percussion and postural drainage works at all. Administering dry gas through an artificial airway causes damage to tracheal epithelium within minutes.45,46 Care should be taken to quickly provide humidification to patients with artificial airways. In intubated pediatric patients the natural airway maintenance and clearance defenses have been impaired.64 An effort to restore these natural defenses offers benefits with much less risk of infection or harm. Exhaled-breath condensate is a technique that samples the airway-lining fluid that has advanced our understanding of airway chemistry. However, regulating humidity is not as easy as it sounds. When mucus is difficult to clear from the airways, it may lead to obstruction. All percussion and vibration devices should be cleaned after each use and between patients. Increased acids in exhaled-breath condensate are present because of acidification of the source fluid from which the acids are derived. Suction as needed. A 2004 Cochrane review revealed only 3 studies that compared active humidification to HME in the neonatal/pediatric population. While most studies have focused on the primary outcome of sputum production, it is not clear whether sputum volume is an appropriate indication for or outcome of airway clearance. Print ISSN: 0020-1324 Online ISSN: 1943-3654. I think that's the wrong way to do it, but it's something I've come across a couple of times, where the physician says, Yeah, I don't really think CPT helps, but your being in that room does.. Caruso's 2009 study of 262 adult patients found a VAP risk reduction of 54% with routine saline instillation.61 A limitation of that study may be that HMEs were utilized to provide humidification, possibly necessitating saline instillation for secretion thinning. The patient's cough will always be our strongest ally in airway maintenance. The concern would be that you could increase oxygen demand and also stress a patient who is already stressed.88 How then, do we deal with secretion clearance in patients with acute asthma? Airway resistance is disproportionately high in children at baseline. A Cochrane review105 of the efficacy and safety of chest physiotherapy in infants less that 24 months with acute bronchiolitis found no improvement in stay, oxygen requirement, or difference in illness severity score.106 France's national guidelines recommend a specific type of physiotherapy that combines the increased exhalation technique and assisted cough in the supportive care of bronchiolitis patients. Bronchiolitics treated with humidified gas may experience a high relative humidity environment that is less likely to tax their natural upper airway.39 Suctioning frequency and secretion amount or consistency was, unfortunately, not evaluated. In the pre-heated high-flow nasal cannula group, 32% of infants with respiratory syncytial virus were managed on room air or blow-by oxygen. Re to: Adjustment to . This result is particular true in the heterotaxy population. A smaller catheter provides more protection to the patient than does a lower suction pressure.52,53 Catheter size is, unfortunately, not reported in all studies. When utilizing low-tidal-volume (low-VT) strategies, keeping dead space to a minimum is vital. Some of the associated conditions with ineffective airway clearance include bronchiectasis, chronic bronchitis, pulmonary edema, respiratory tract infection, acute respiratory distress syndrome (ARDS), and pulmonary embolism. The common thought process with most pediatric clinicians is that it cannot hurt, maybe it can help, but is this actually true? It helps with debris removal, which we found out when we were doing liquid lung ventilation. 1. C: The choke point catches the mucus and creates turbulent flow, which aerosolizes the mucus. The negative pressure from the suction catheter triggers the ventilator, and the incoming gas forces the secretions away from the suction catheter. Small changes in airway diameter due to edema, secretions, foreign body, or inflammation can lead to drastic changes in resistance. Repeat episodes of acid reflux causes esophageal-tissue inflammation, with associated dampening of vagal reflexes. Increased perfusion and decreased ventilation to the dependent lung is more pronounced in small patients. Ineffective Airway Clearance Nursing Diagnosis & Care Plan Many disease processes and acute situations can affect the airway. When percussion or vibration is omitted, longer periods of simple postural drainage can be performed. Bach et al found that improving peak cough flow is the single critical factor in removing an artificial airwayboth ETTs and tracheostomy tubes.94 Dohna-Schwake et al evaluated 29 pediatric neuromuscular patients for an improvement in peak cough flow after intermittent positive-pressure breathing treatment with assisted coughing, which demonstrated a drastic improvement in peak cough flow.95, Because of the neuromuscular patient's poor respiratory muscle strength, the airway-clearance method should focus on increasing the amount of air distal to the mucus (increasing FRC) as well as assisting the patient with a cough. Overuse of airway clearance procedures was noted despite national guidelines not supportive of routine suctioning of the baby who is breathing, crying, and has good muscle tone. Optimal humidification results in properly conditioned inspiratory gas. Their high chest-wall compliance can increase the difficulty of expanding the dependent lung. Alveolar collateral channels in older children and adults facilitate gas exchange around obstructing mucus. During airway peristalsis the airway becomes narrowed at the point of the mucus. Dick Martin, at Origin, took that over. It is most commonly caused by a viral infection in the lower respiratory tract, and is characterized by acute inflammation, edema, necrosis of the epithelial cells of the small airways, increased mucus production, and bronchospasm.105 CPT is thought to assist in airway clearance in infants with bronchiolitis. Catheter insertion alone may dislodge thousands of bacteria; a flush of saline increases this and potentially distributes them distally into the lung, fostering the concern that routine saline instillation may increase the incidence of VAP.

If saline is instilled before suctioning, the clinician must remember the potentially important differences between neonatal and adult airway chemistry, in particular the antimicrobial component of airway mucus in the neonate. This contradicts the statement that a slight acidosis of the airway lining is bacterial static or lung-protective. Synergistically, airway-lining fluid acidification traps what would be volatile ammonia (NH3) by protonation into the non-volatile cation ammonium (NH4+). To find information on adverse effects from chest physiotherapy and postural drainage we looked as far back as the late 1970s, and found only 2 studies focused on children.111,112 A positive effect was never demonstrated, and in one study the CPT group (the CPT included percussion and postural drainage) had a significantly longer duration of fever.113 A review of CPT in 106 infants on mechanical ventilation found there is not enough evidence to determine whether active CPT was beneficial or harmful.79 Nor was there enough evidence to determine if one technique was more beneficial than others in resolving atelectasis and maintaining oxygenation. Children, particularly infants, are prone to complete airway obstruction that can lead to atelectasis and the elimination of expiratory flow. Proper humidification effects more than just sputum viscosity. Nursing diagnoses of newborns with sepsis in a Neonatal. Although in the out-patient setting, Girard et al studied oscillatory PEP (with the Flutter VRP1) in 20 patients with asthma, mucus hypersecretion, and hypersensitivity to dust mites as a major allergen. * Mark Rogers RRT, CareFusion, San Diego, California. Airway-clearance techniques appear likely to be of benefit in the maintenance or prevention of respiratory-related neuromuscular disease complications and are probably of benefit in treating atelectasis in mechanically ventilated children. Thank you for your interest in spreading the word on American Association for Respiratory Care. The American Association for Respiratory Care clinical practice guidelines on postural drainage69 define difficulty clearing secretions as a sputum production greater than 2530 mL per day. The clinical picture of airway collapse often prompts CPT or bronchodilator orders. Vibrations can be performed by placing both hands (one over the other) over the area to be vibrated and tensing and contracting the shoulder and arm muscles while the patient exhales. Thus, the routine practice of deep suctioning should probably play a limited role in the management of pediatric viral illnesses. One of the staples of respiratory care has been chest physiotherapy. ARDS causes impairment in gas exchange, as a result, the lungs could not provide enough oxygen. An in vivo adult study comparing the use of heated-wire circuits to non-heated-wire circuits in the delivery of humidified gas reported an increase in sputum volume with the usage of non-heated-wire circuits.48 Perhaps there was a reduction in retained secretions or just increased rainout in the large airways. High risk for altered parenting . Implications for asthma pathophysiology, Airways in cystic fibrosis are acidified: detection by exhaled breath condensate, pH in expired breath condensate of patients with inflammatory airway diseases, Exhaled breath condensate acidification in acute lung injury, How acidopneic is my patient? Mr Walsh presented a version of this paper at the 47th Respiratory Care Journal Conference, Neonatal and Pediatric Respiratory Care: What Does the Future Hold? held November 57, 2010, in Scottsdale, Arizona. Some models of mechanical percussor or vibrator are appropriate only for the newborn or premature infant, whereas other models provide a stronger vibration appropriate for the larger child. There is a perception that airway clearance may not help, but it won't hurt either. The authors have disclosed no conflicts of interest. I wouldn't recommend it as a way of clearing secretions. Breast care plan goals for tracheostomy include maintaining a patents upper. Marked hyperinflation is seen in some. The aerosolization of contaminated water in hospital humidifiers and/or room humidifiers is a potential source of nosocomial infection.42 Specifically, small room humidifiers have been associated with passing Legionella,43 are hard to clean, and require between-patient sterilization and the use of sterile or distilled water to prevent cross-contamination. Research will continue to focus on new and novel therapies such as airway alkalization, low-sodium solutions for suctioning, nebulized hypertonic solutions, and proactive airway humidification. 3. If they aren't, then we did something wrong and we need to either re-recruit the lungs or make other changes to the ventilator. Many of our staff push us to use such drugs, which are typically anticholinergic agents, which can have systemic adverse effects, including tachycardia and hypertension. Following the introduction of heated high-flow nasal cannula, all the respiratory syncytial virus infants received humidified gas, some with only humidified air. If we provide proper maintenance, the need for additional airway clearance (above the patient's own) will be minimized. Physical activity and exercise programs have been shown to augment airway clearance. However, David Tingay's team at Murdoch Children's Research Institute in Australia published a series of articles on closed versus open suctioning.13 They found significantly better secretion clearance with open suctioning, because the airway collapse squeezes the secretions out to the larger airways where the suction catheter can pull them out. In a study designed to determine the contribution of these maneuvers for mucus clearance there was no demonstration of improvement in mucus clearance from the lung when percussion, vibration, or breathing exercises were added to postural drainage.6 The study also showed that forced expiration technique was superior to simple coughing, and when combined with postural drainage was the most effective form of treatment.7 This, however, requires a level of cognitive ability not afforded to small children. But a multicenter randomized trial with 496 previously healthy hospitalized bronchiolitic patients found that that modified physiotherapy regimen (exhalation technique and assisted cough) did not significantly affect time to recovery107,108, A common chest radiograph finding in the postoperative patient is atelectasis, which is associated with morbidity. It is effective for debris mobilization: we've shown that. I think something that's coming soon, or is now on the market, is bullets of what would have been known a couple of years ago as perflubron for suctioning. Facilitated tucking may reduce the pain of suctioning in small infants. Doing recruitment maneuvers after suctioning is interesting, but I would say that it's not the in-line suction catheter vs the open. 2. Brian, our anesthesiology colleagues commonly use some systemic drugs, such as glycopyrrolate, to try to dry up lung secretions in the operating room. Airway-clearance techniques are used to assist in the removal of bronchial secretions and are recommended at the first indication of lung involvement. Further, endotracheal tube (ETT) leaks promote loss of humidity to the atmosphere, resulting in less exhaled gas to the HME, reducing its efficiency. A hospitalized client with Hodgkin's disease is at risk for ineffective airway clearance and impaired gas exchange related to compression of the trachea by enlarged lymph nodes. risk for ineffective Airway Clearance is possibly evidenced by risk factors of tracheo-bronchial obstructionmucosal edema and loss of ciliary action with smoke inhalation; circumferential full-thickness burns of the neck, thorax, and chest, with compression of the airway or limited chest excursion, traumadirect upper airway injury by . We only looked at the 8.4%, because that's how it comes. Exhaled-breath condensate is obtained noninvasively during exhalation into a condenser. Department of Respiratory Care, Children's Medical Center Dallas, Dallas, Texas. For example, if exhaled-breath-condensate pH falls prior to the onset of clinical symptoms, it is probably useful as an early marker, heralding the onset of various inflammatory lung diseases. So it is hard for the respiratory therapist. That being said, Hess questioned, in a Journal conference summary regarding airway clearance, Does the lack of evidence mean a lack of benefit?1 Reasonable evidence is limited in this patient population, and is far from conclusive, so we have taken the liberty of utilizing experience and supportive evidence from adult clinical trials to assist in our quest to clarify the role of airway maintenance and clearance in pediatric acute disease. PaO2/FIO2 quantifies oxygenation impairment and may help determine the benefits of airway-clearance therapies. A lot of people are scared to turn up the ventilator knobs during in-line suctioning or shortly after, but they're not scared to squeeze a bag harder, because those pressures are not documented. We do not capture any email address. Newer techniques considered part of chest physical therapy (CPT) include maneuvers to improve the efficacy of cough, such as the forced expiration technique, intrapulmonary percussive ventilation, positive expiratory pressure (PEP) therapy, oscillatory PEP, high-frequency chest compression, and specialized breathing techniques such as autogenic drainage. In Boston we researched recruitment maneuvers, and I was impressed that sustained inflations tended not to work very well. An important clinical advantage to heated-wire circuits is the reduction in circuit condensate. Just a bunch of fairly randomly directed comments. Outcome Criteria V Return of respiratory status to baseline parameters for rate, depth and ease (specify). Radiograph may show nonspecific findings of airways disease with peribronchial thickening, atelectasis, and air-trapping. Perhaps at the bedside the clinician should decide what method should be used, with the primary goal of secretion removal versus lung-volume retention, and occasionally do open suctioning. extrauterine life . From an administrative standpoint, all of these airway-clearance modalities are an education nightmare, because the therapists have to know the ins and outs of each one. One of the things I think we've learned in suctioning neonates is how to manipulate the ventilator to re-recruit the lungs rather than allowing them to desaturate. Have you had any experience with that? Ineffective Airway Clearance NURSING DIAGNOSIS: Ineffective Airway Clearance Actual Risk for (Potential) Related To: [Check those that apply] Decreased energy and fatigue Ineffective cough Tracheobronchial infection Tracheobronchial obstruction (including foreign body aspiration) Copious tracheobronchial secretions Perceptual/cognitive impairment Brian, regarding airway alkalization, you seemed to imply that at least Pseudomonas grows better in an acidic pH, but later you said that maybe acidification is a host defense. Postural drainage uses gravity to facilitate movement of secretions from peripheral airways to the larger bronchi where they are more easily expectorated. This action results in swollen turbinates, which can lead to nasal congestion and increase airway resistance, thus escalating a patient's respiratory work load.44. Investigations have been conducted to determine the relative importance of percussion, vibration, and postural drainage. The clinician must account for the low humidity in the hospital setting and understand that the low-humidity state causes physiologic changes in the airway. Maintaining FRC with positive airway pressure could assist in maintaining airway caliber. Compared to simple postural drainage, chest percussion reduced the amount of sputum mobilized.8 Manual self-percussion did not increase the amount of sputum expectorated, compared to simple postural drainage, in a group of patients with cystic fibrosis (CF).8,9. The therapy utilized in the acute phase must be evaluated on a case-by-case basis. Several mechanical vibrators are commercially available. The practice of suctioning assists clinicians in obtaining the main goal of all bronchial hygiene, a patent airway, and this remains the most common procedure performed in neonatal and pediatric intensive care units (ICUs).50 Instructors teach the dos and don'ts of suctioning as some of the first words of wisdom imparted to new therapists. Now that I'm an administrator; I find that we can get a lot of revenue for it. Invasive pH probe measurements and tracheobronchial-secretion measurements indicate that airway pH in healthy individuals is mildly alkaline, with a pH of 7.57.8,13 and correlates nicely with exhaled-breath-condensate pH.14 There has been growing literature regarding changes in exhaled-breath-condensate pH in acute and chronic respiratory diseases that are characterized, at least in part, by inflammation. Nasal CPAP has many well researched benefits in neonates. As soon as the catheter is inserted into the airway, lung-volume loss begins. Risk for infection related to lowered immune response in newborn. At times gas exchange may be impaired, indicating a need for airway clearance. To further complicate the situation, patients with viral upper respiratory tract infections often have humidity deficit due to increase in minute ventilation, decreased oral intake, and fever. However, the potential benefits of closed suctioning include continued delivery of oxygen, supportive positive pressure, lower risk of nosocomial infection, and reduced staff exposure. Risk for delayed surgical recovery. When a neuromuscular patient acquires a viral infection, it leads to increased mucus production and ventilation/perfusion mismatch, which can lead to respiratory fatigue if aggressive pulmonary toilet is not initiated. Secretion removal in the non-dependent lung is supported by increased lung recruitment, allowing for larger expiratory volume and faster flow. One of the staples of respiratory care has been chest physiotherapy and postural drainage. Investigators demonstrated that the pH of exhaled-breath condensate is, in fact, low (acidic) in multiple pulmonary inflammatory diseases, including asthma, COPD, CF, pneumonia, and acute respiratory distress syndrome (ARDS).1518 Some have coined the term acidopneic to describe acidic breath.19. Negative intrathoracic pressure may assist in collateral ventilation around secretions, however few the channels. If you spend more time at the bedside before and after suctioning, you could alleviate a lot of that and manipulate the ventilator to keep the VT consistent. Until then we will continue to offer a wide range of airway-clearance techniques to match the diverse patient population. If clinicians used only therapies that have been proven to work, we would be back to the basics. Activation of inflammatory cells, such as neutrophils, eosinophils, and macrophages, has been implicated in the pathophysiology of these diseases. I'm interested in seeing some controlled studies, rather than just approval, but it does potentially make sense to use that as opposed to something like saline. Similarly, with perflubron; it was approved long ago as an agent for imaging because it's radiopaque. I have to document the ones I set on the ventilator. It's slightly acidic compared to 7.88.0 lung environment, so it could make things worse. Kostikas et al compared the exhaled-breath-condensate pH to the number of sputum eosinophils and neutrophils and found tight correlations in diseases such as asthma, COPD, and bronchiectasis.17 However, this has not been described in patients with acute lung injury. It's interesting that it has some anti-inflammatory properties, and it also has a very low surface tension, of about 10 dyn/cm, meaning it spreads quickly and then rapidly becomes volatile. b. The Pulmonary Therapies Committee for the adult population investigated the amount of sputum produced to determine the effect of airway clearance. So other studies should compare nothing or adequate humidification, and suctioning to whatever the new technique is. It is characterized by sudden, progressive pulmonary oedema and hypoxemia unresponsive to oxygen supplementation. Some of these patients need lots of lavaging, and perflubron may deliver some oxygen while allowing you to remove more secretions. Maybe that's something we shouldn't look at, but it may keep administrators advocating for less CPT and those types of things. However, if during a tussive squeeze the positive pleural pressure exceeds that of the airway pressure, the airway may collapse. Active humidifiers capable of quick warm-up and self-regulation (temperature and water levels) that require few disruptions offer many advantages. Temperature importance was validated by Kilgour et al, in sheep. 3). This low-humidity state causes physiologic changes in the upper airway. Clinicians can perform percussion with the patient positioned in various places, including their lap with infants and small children. The theory is that biofilm forms in the ETT, and when we suction and lavage, we wash the biofilm down into the lungs. In November of 2006 the Pulmonary Therapies Committee began preliminary discussions on the establishment of guidelines for the clinician on the use of best adjunctive therapy for the CF patient. The use of the appropriate airway-clearance therapy in the acute setting appears to depend on the patient condition and physician preference. Increased nasal swelling and epistaxis are common traumatic results of deep suctioning. Removing secretions with bulb suctioning reduces resistance, allows for enhanced natural humidification, and decreases the risk of aspiration of virally loaded secretions. But if you loosen up secretions and then put a bloody bag on and push it down deep into the airway, you may be causing more problems. Position to decrease secretions. I agree with you. I used to be a fan of in-line [closed-system] suctioning, but now I don't think it really helps, and I think a lot of times it messes up your airway mechanics more than anything else. The clinician must remember, first, do no harm., Patients who suffer from asthma are at risk for inhibited airway clearance because their airways are narrowed by bronchospasm and/or inflammation. Thank you for including the study on suctioning and VAP prevention,1 which was interesting to me because I see the wholesale banning of suctioning in the neonatal ICU because of concern about VAP prevention. For over 30 years, postural drainage, manual or mechanical percussion, vibration, and assisted coughing have proven to be beneficial in removing the secretions of CF patients. Other studies have reported that percussion without postural drainage or cough produced minimal change in mucus clearance. Babies born several weeks before their due date usually have lungs that are not fully developed. Risk of impaired gas exchange. Airway alkalization, such as with phosphorus-buffered saline, sodium bicarbonate, or glycine, may increase ciliary beat, reduce exhaled nitric oxide (a marker of inflammation),66 increase mucociliary clearance, improve the uptake of albuterol,31 decrease viscosity, reduce VAP in mechanically ventilated21 patients, and decrease epithelial damage. Lasocki et al showed that that's what happens,2 and I think it explains why more secretions are removed with open-circuit suctioning. CF is considered the cornerstone disease process for secretion clearance. Thick and viscid mucus is such a common feature that at one time the disease was referred to as mucoviscidosis.84, Mucociliary clearance is variable in CF, with some patients having severe impairment, whereas others have normal clearance. Then we clog the ETT because we're so focused on FRC management, and we don't dare risk that, and yet they'll plug off the ETT in a heartbeat if you've gone a long time without suctioning. Mechanical ventilation is often needed to achieve adequate gas exchange. This practice reduces the humidity deficit and potentially lowers airway resistance. Risk for Ineffective Airway Clearance related to suppression of respiratory system Impaired Skin Integrity related to constant activity, diarrhea Altered Nutrition: Less than Body Requirements related to vomiting and diarrhea, uncoordinated suck and swallow reflex, hypertonia secondary to withdrawal pattern -Risk for impaired gas exchange -Risk for impaired fetal gas . In 2009, Solomita and colleagues proved the use of heated-wire circuits reduced water-vapor delivery to adult patients ventilated with no bias flow.48 However, pediatric settings on a ventilator that utilizes bias flow may produce entirely different results. The mucus is then propelled out of the airway. Suctioning solution instillation may be beneficial; however, careful consideration of composition, timing, and volume should occur. Closed-system suctioning recovery spontaneously occurred in the non-paralyzed patients on HFOV, in approximately one minute.58. CPT increases intrathoracic pressure and can significantly increase abdominal pressure, possibly leading to episodes of gastroesophageal reflux, by compressing the stomach.74 The infant's natural defense mechanisms against gastroesophageal reflux are weakened during CPT. The airways undergo compression that creates moving choke points or stenosis that catch mucus and facilitate expiratory air flow, propelling the mucus downstream34 (Fig. In 30 neonates, the use of a 6 French catheter and a suction pressure of 200 mm Hg (which is considerably greater suction pressure than is currently recommended in the United States) did not produce important adverse effects. There is little evidence that airway-clearance therapies in previously healthy children with acute respiratory failure improves their morbidity. Risk for Ineffective Airway Clearance as risk factors may include tracheal obstruction; swelling, bleeding, and laryngeal spasms. Airway-clearance techniques may be of benefit in minimizing re-intubation in neonates, but are of little or no benefit in the treatment of acute asthma, bronchiolitis, or neonatal respiratory distress, or in patients mechanically ventilated for acute respiratory failure, and it is not effective in preventing postoperative atelectasis.
