![]() ![]() Obviously, there is a need for more studies to increase the body of scientific evidence on this topic ( 9). This absence of evidence, however, does not necessarily mean an absence of efficacy. Their aim is to reduce airway obstruction caused by secretions occupying the airway lumen and so prevent respiratory tract infections, re-expand the collapsed areas of the lung, thus improving gas exchanges and decreasing the inflammatory response ( 1– 4).Ī wide range of treatments, techniques and devices are present in the scientific literature for managing bronchial encumbrance in respiratory physiotherapy but their very multiplicity begs the question in daily clinical practice: “which of these treatments is it better to use to obtain the better result in my patient?.” Up to now, for all ACTs there is insufficient evidence to prove their efficacy and effectiveness in different clinical scenarios or to affirm the superiority of one technique over another ( 5– 8). The term airway clearance techniques (ACTs) refers to a variety of different strategies used to eliminate excess secretions. 8, 2020.The management of bronchial secretions is one of the main problems encountered in a wide spectrum of medical conditions ranging from respiratory disorders (e.g., COPD, bronchiectasis, cystic fibrosis) to neuromuscular disorders (e.g., ALS) to patients undergoing either thoracic or abdominal surgery. Major disorders of esophageal hyperperistalsis: Clinical features, diagnosis and management. Peroral endoscopic myotomy for esophageal motility disorders. In: Sleisenger and Fordtran's Gastrointestinal and Liver Disease: Pathophysiology, Diagnosis, Management. Esophageal neuromuscular function and motility disorders. Diffuse esophageal spasm (corkscrew esophagus).There are no known risk factors for esophageal spasms. ![]() There are two types of esophageal spasms - distal esophageal spasm and hypercontractile esophagus, also referred to as jackhammer esophagus. Esophageal spasms make it difficult for the muscles in the walls of your lower esophagus to coordinate in order to move food to your stomach. However, they appear to be related to atypical functioning of nerves that control the muscles you use when you swallow.Ī healthy esophagus usually moves food into your stomach through a series of coordinated muscle contractions. It's not clear what causes esophageal spasms. If you experience squeezing chest pain, seek immediate medical care. The squeezing chest pain associated with esophageal spasms also can be caused by a heart attack.
