Critical postoperative complications can be preceded by rising EWS. Interventional studies are needed to evaluate whether EWS can reduce the severity of postoperative complications and mortality for surgical patients through early identification and intervention.
Gastroesophageal reflux disease (GERD) causes chronic cough and triggers asthma. Mechanisms of reflux-associated chronic cough include micro- and macroaspiration, laryngeal injury, and a vagally mediated reflex. An empiric trial of a proton pump inhibitor in patients without other etiologies of cough found through diagnostic testing may be an effective diagnostic strategy for GERD-associated cough. In GERD-associated asthma, there is evidence of neurogenic inflammation. Medical or surgical therapy of GERD results in asthma symptom improvement in about 70% of patients. A 3-month empiric trial of omeprazole, 20 mg daily, followed by esophageal pH testing in drug nonresponders, is the most cost-effective way of diagnosing asthma triggered by GERD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
