['Stress-related mucosal damage is an erosive process of the gastric lining resulting from abnormally high physiologic demands. To avoid the morbidity and mortality associated with significant bleeding from the damage, prophylaxis with an acid suppression medication is given. This is especially common in stroke victims. Recent studies have suggested a link between acid suppression therapy and nosocomial pneumonia, specifically implicating proton pump inhibitors (PPI), a potent acid suppression medication, as the culprit. In this retrospective study, we reviewed the medical records of admitted intracerebral hemorrhage (ICH) patients and determined if there is a link between PPI prophylaxis and nosocomial pneumonia in our ICH population.', 'Medical records of 200 ICH patients admitted to the First Affiliated Hospital of Chongqing Medical University were reviewed from January 1, 2008 to October 31, 2009. PPIs were the only accepted form of acid suppression therapy. In all, 95 patients were given PPI prophylaxis, whereas 105 patients did not receive any form of acid suppression.', 'The unadjusted incidence rate of pneumonia in the PPI prophylactic group was 23.2%, and 10.5% in patients not having received prophylaxis. Additionally, patients treated with PPI prophylaxis were more likely to be critically ill, defined by an increase in conscious disturbance and dependency on mechanical ventilation and/or a nasogastric tube.'] Does proton pump inhibitor prophylaxis increase the risk of nosocomial pneumonia in patients with an intracerebral hemorrhagic stroke?
