If we provide proper maintenance, the need for additional airway clearance (above the patient's own) will be minimized. 1. It appears, at least in the CF population, that adherence is vitally important. Frequent suctioning of the upper airway is common in infants with viral respiratory illnesses. In that study, which was in adults, they theorized the opposite, that the lavage clears and prevents the biofilms. Coughing is associated with a wide assortment of clinical associations and etiologies . A plateau pressure of 40 cm H2O for 40 seconds is just not long enough to recruit the whole lung. We might turn up the PEEP and come back 15 minutes later and the lungs are re-recruited, but now the patient's oxygen saturation is dangerously high. Nursing Diagnosis: Risk for Ineffective Tissue Perfusion related to inadequate oxygen in the tissues or capillary membrane Desired Outcome: The patient will exhibit enhanced perfusion as evidenced by warm and dry skin, strong peripheral pulses, acceptable vital signs, adequate urine production, and the absence of swelling. Reflux episodes, as measured with a pH probe reading of < 4, occurred most often during crying.75 Button and colleagues reported no differences in heart rate or oxygen saturation during reflux episodes,75 which illustrates what some call silent aspiration. The smarter suctioning approach consists of suctioning only when a clinical indication arises, not on a scheduled basis.51 In the neonatal population, limitation of pre-oxygenation to 1020% above baseline FIO2 is often recommended.51 When developing standards for tracheal suctioning, healthcare providers should address catheter size, duration of suctioning, suctioning pressure, deep versus shallow technique, open versus closed technique, saline instillation, lung pathology, and ventilation mode. I think we're learning more each day, but it's something I wanted to bring back up. Probably it's the lack of humidity. The possible advantages of normal saline for adults and low-sodium saline solution in neonates prompt careful consideration of routine pre-suctioning saline instillation in the pediatric population. In our institution, one-quarter-strength use of standard HCO3 8.4% is instilled in 12 mL volumes intratracheally as a mucolytic. Because all of these therapies share the same goal, the term bronchial drainage or hygiene is often employed to describe them collectively. Position to decrease secretions. There is a vicious circle of lower-esophageal-sphincter relaxation and more gastroesophageal reflux. An approach to the pathogenesis and preventive strategies emphasizing the importance of endotracheal tube, Spare the cough, spoil the airway: back to the basics in airway clearance, Buffering airway acid decreases exhaled nitric oxide in asthma, Mucous-controlling, surface-active, and cold and cough agents. Similarly, with perflubron; it was approved long ago as an agent for imaging because it's radiopaque. So it is hard for the respiratory therapist. It is a life-threatening condition of capillary endothelial injury and diffuse alveolar damage. Outside of the neonatal ICU, with large-VT recruitment, it just depends on how much of an advocate you are and how much volutrauma it creates. Exhaled-breath condensate is obtained noninvasively during exhalation into a condenser. A cough is one of the most common medical complaints accounting for as many as 30 million clinical visits per year. Despite these difficulties and differences, careful research with the intent of first, do no harm must continue. Percussion is thought to loosen secretions from the bronchial walls. Diaphragm compression from hyperinflation limits the cough mechanism. This decreases mucociliary activity, which further hinders airway clearance (Table 2).89,91,93, A key factor in secretion clearance is being able to get enough air distal to the mucus. 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? Ineffective airway clearance . Properly conditioned inspiratory gas maintains ciliary motility, decreases airway hyper-reactivity, and helps keep mucus from undergoing dehydration. As everybody knows, when you ventilate a child and have an ETT in place, within hours to days you'll have an incredible amount of secretions, which drives nurses, therapists, and physicians crazy. I think it's important to recognize that we don't have a lot of good evidence on many elements of the suctioning guidelines.1 Can you comment on hyperventilation, hyperoxygenation, and the use of higher VT during suctioning? Da Silva et al found, in a study of 45 children < 1 year old, that adventitious breath sounds and sputum production had the highest positive predictive value for insufficient airway clearance.70 But does the presence of adventitious breath sounds indicate that the patient is getting worse? 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. She also had weak muscle tone. Pathology examination of canine lungs immediately after CPT revealed large atelectatic areas adjacent to the chest wall where CPT was performed.78 Proper location of CPT is difficult because of the relatively large abdominal size of neonates. Saline suctioning isn't a matter of saline versus no saline, but it's how you put it in there. Bronchoconstriction induced by citric acid inhalation in guinea pigs: role of tachykinins, bradykinin, and nitric oxide, Protons: small stimulants of capsaicin-sensitive sensory nerves, pH effects on ciliomotility and morphology of respiratory mucosa, Ciliary beat frequency of human respiratory tract by different sampling techniques, pH- and protein-dependent buffer capacity and viscosity of respiratory mucus. 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. Alterations in position serve to redistribute ventilation, aid in gravitational movement of secretions toward the large airways, and can foster gas-liquid pumping.34 The benefits of frequent turning are often masked by patient decompensation during and after positioning. This technique requires one caregiver to place the infant in the fetal position while the other is suctioning.63 Closed suctioning with appropriate catheter size provides shorter recovery times, less pulmonary volume loss, and decreased circuit disconnections. An important clinical advantage to heated-wire circuits is the reduction in circuit condensate. The lack of scientific rigor, among other issues, has led to a deficiency of high-level evidence. This attitude can lead to inappropriate orders and inadvertent complications.

The reduction in clearance is believed to be caused by the increased volume of respiratory secretions and the abnormally thick mucus. Ineffective airway clearance is characterized by the following signs and symptoms: Abnormal breath sounds (crackles, rhonchi, wheezes) Abnormal respiratory rate, rhythm, and depth Dyspnea Excessive secretions Hypoxemia/cyanosis Inability to remove airway secretions Ineffective or absent cough Orthopnea Goals and Outcomes Regarding the financial aspect, remember that, regardless of the device or method, airway clearance is billed under one Current Procedural Terminology billing code number. Using the Murray Lung Injury Score, he was able to correlate severity (r = 0.73, P < .001) and concluded that exhaled-breath-condensate pH is a representative marker of acute lung injury caused by or accompanied by pulmonary inflammation.18 More recently, Pugin and colleagues found that patients mechanically ventilated for various reasons (eg, ARDS, pneumonia, and after cardiac surgery) had a substantially lower exhaled-breath-condensate pH than healthy controls. Saline instillation prior to suctioning remains a controversial topic in pediatrics, particularly with neonates. Is there equipoise? Sliding down in the bed or a slumped posture prevents proper lung expansion. A topic we're lecturing on at this year's AARC [American Association for Respiratory Care International Respiratory Congress] is that hand-ventilating kids potentially makes things a lot worse, because hand ventilation is very uncontrolled. This paper focuses on the pediatric airway clearance and maintenance aspect of acute respiratory diseases, specifically in the hospital environment, biophysical and biochemical characteristics of the lung that prevail during pulmonary exacerbations, physiology and pathological processes unique to children, and other considerations. In the CF patient there is an increased number of goblet cells and hypertrophy of submucosal glands, which leads to an increase in secretions and sputum production. 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. There is a perception that airway clearance may not help, but it won't hurt either. 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. 3. Abstract Purpose: This descriptive, observational study explored the practice of airway clearance of the term newborn at birth. But because it's so irritating, it does carry risks, and if you use bicarbonate, I would be cautious about it. The second thing is about closed suctioning. In patients receiving heliox therapy, the nitrogen balance is often completely replaced with helium. The oldies but goodies. Returning the airway to a normal pH may be beneficial. Treatment of viral upper respiratory infection largely consists of supportive measures such as applying dry medical gases. Newborn complications . 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. Here are 11 nursing diagnoses common to pneumonia nursing care plans (NCP). NANDA-I diagnosis: Ineffective Airway Clearance (00031) Definition: . The lack of efficient HMEs for smaller patients seems to also guide this practice.49. I don't know about dilution. Any airway-clearance modality that causes crying may encourage gastroesophageal reflux. No, but it intrigues me. It was very effective at removing debris. Pain and sedation following surgery can decrease sigh and cough efforts. The fact that exhaled-breath condensate acidity is the result of airway acidification is supported by general chemistry concepts as well as several lines of evidence. One is that I wouldn't call it CPT. In open suctioning, volume loss is independent of catheter size.56 This may be explained by the probable presence of turbulent flow between the ETT and suction catheter during closed suctioning.52 The concept that closed suctioning is better because it prevents volume loss may be incorrect. Gessner and colleagues examined the relationship between exhaled-breath-condensate pH and severity of lung injury in 35 mechanically ventilated adults. Airway inflammation has a central role in the development and progression of acute lung injury. They corrected that by increasing the suctioning pressure to 300 mm Hg in adults. Restoring the natural isothermic boundary is accomplished with proper conditioning of dry inspiratory gas while the natural airway cannot. Endotracheal suctioning is basic intensive care or is it? Lung volume and cardiorespiratory changes during open and closed endotracheal suction in ventilated newborn infants, Volume not guaranteed: closed endotracheal suction compromises ventilation in volume-targeted mode, The effect of suction method, catheter size, and suction pressure on lung volume changes during endotracheal suction in piglets, Closed suctioning of intubated neonates maintains better physiologic stability: a randomized trial, Effect of closed endotracheal suction in high-frequency ventilated premature infants measured with electrical impedance tomography, Physiologic impact of closed-system endotracheal suctioning in spontaneously breathing patients receiving mechanical ventilation, Effect of endotracheal suction on lung dynamics in mechanically-ventilated paediatric patients, Saline instillation before tracheal suctioning decreases the incidence of ventilator-associated pneumonia, A low-sodium solution for airway care: results of a multicenter trial, Endotracheal suctioning: there's more to it than just technical care, Ventilator-associated pneumonia or endotracheal tube-associated pneumonia? Sulfomucins are prevalent at birth, and sialomucins become evident over the first 2 years of life.10 Submucosal glands that are responsible for producing most of the body's mucus are 5% larger in the pediatric airway11 than in the adult airway. 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. When we first found out that the lung is so acidic, we were wondering whether this acidification is actually beneficial. . Clinicians can perform percussion with the patient positioned in various places, including their lap with infants and small children. Airway secretions are relatively dehydrated and viscous. What are some of the suggested interventions for this diagnosis? * Mark Rogers RRT, CareFusion, San Diego, California. 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. A lot of people are not using the 8.4%: they're diluting it down to 24%. You need the air behind the mucus to push it out to the main airway where you can suction it. This mechanism requires narrowing of the airway, but complete obstruction will inhibit this transfer. In a small study of 17 infants, a catheter-to-ETT diameter ratio of 0.7 proved most effective without increasing the incidence of adverse outcomes.53 According to Argent and colleagues, a smaller catheter and a higher suction pressure produced volume-loss equal to that of a larger catheter and a lower suction pressure.53 This brings into question the common practice of setting the suction strength based on the patient population rather than the catheter size. Studies have shown the cilia from CF patients to be normal, although chronic inflammation may result in a loss of ciliated cells.85. McKiernan and colleagues reported results from a retrospective study and showed a decrease in intubation rate, from 23% to 9%, when nasal cannula was heated and humidified. 2 . Although mostly water vapor, exhaled-breath condensate contains other constituents such as small molecules, proteins, and even DNA.12 The majority of these constituents are aerosolized by turbulent flow in the larger airways. Do you have data on the optimal operational approach for a secretion-clearance program? It's slightly acidic compared to 7.88.0 lung environment, so it could make things worse. In pediatric patients outside of the cardiac ICU, I think it's fine to pre-oxygenate them. Modifying CPT by excluding head-down positions may decrease the number of reflux episodes.75 During modified CPT, infants are more likely to remain calm. Ineffective airway clearance occurs when the body loses the ability to maintain a patent airway. The clinical picture of airway collapse often prompts CPT or bronchodilator orders. maternal newborn clinical assignment develop nursing diagnosis for the following patients: labor patient in active labor with an epidural postpartum patient . 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. 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 Scant data support or oppose its use, but it is reportedly anecdotally successful and safe. In infants, especially premature infants, the airway cartilage is less developed and more compliant than that of older children and adults.37 This increased yielding leads to greater airway collapse at lower changes in pleural and airway pressure. Usually, protective mechanisms such as microscopic organisms or coughing keep the respiratory tract free of obstructions and secretions. In prevention of artificial-airway occlusion, suctioning is second only to humidification. Effective cough is based on a large breath (increased FRC) prior to a forceful expiration. 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. Risk for suffocation. Secretion clearance techniques: absence of proof or proof of absence? Depending on your department and your therapist relationship to physicians, sometimes they'll order therapies just because they want you to see the patient more frequently. It sounds safer, but I have no data. 3). Problems with the baby's heart or lung development include . Neonates need provider-enhanced small-airway stabilization. And if you're doing a recruitment maneuver after either open or closed suctioning, it's actually probably better than what you're describing. Although that approach increases the number of clinicians available to assist with secretion clearance, the overall process tends to be inefficient. The future of airway-clearance techniques will continue to evolve. Unfortunately, this pride has not produced convincing evidence that would otherwise guide safe practice. Secretion removal in the non-dependent lung is supported by increased lung recruitment, allowing for larger expiratory volume and faster flow. Since respiratory disease is the most common diagnosis among acute pediatric patients admitted to the hospital,75 unnecessary airway-clearance therapies substantially increase costs to the patient and hospital. a. 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. 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. Hierher what 9 nursing care floor fork tracheostomy and tracheotomy. Much pride is derived from a clinician's ability to suction an airway without an adverse event. Unfortunately, more questions than answers remain. Without expiratory gas moving against it, the mucus becomes trapped. b. Efforts to increase FRC can be valuable tools in the airway-clearance arsenal. In Airway Clearance for the Term Newborn, Adams et al. Increased perfusion and decreased ventilation to the dependent lung is more pronounced in small patients. Which of the following measures would the nurse take first to help ensure that breathing and blood oxygen saturation remain adequate? Until then we will continue to offer a wide range of airway-clearance techniques to match the diverse patient population. Respiratory rate, VT, and ratio of VT to respiratory rate significantly worsened after closed suctioning, and recovery time was longer in the muscle-relaxed patients. 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.
