Esophageal stricture is not reported to be a common complication of nasogastric intubation. Two patients who had a Levin tube inserted in the stomach for nutrition during a prolonged coma, and finally presented with a severe esophageal stricture were observed and treated. The clinical history of the patients suggests that the pathogenesis of this lesion is probably multifactorial, secondary to induced gastroesophageal reflux, impaired esophageal clearance, high gastric acid output, and use of steroids. Jejunostomy feeding, rather than nasogastric feeding, is probably a better means to provide nutritional support in comatose patients, thus averting the risk of such a serious complication. Esophageal replacement with left colon interposition appears the treatment of choice for these severe esophageal strictures.

Monocrystalline antimony electrodes (crystallographically oriented monocrystalline antimony; COMA) are known to be sensitive to oxygen and to pH. Accordingly, it has been shown that COMA electrodes can be used for the measurement of tissue oxygen tension provided the pH remains constant or is accounted for by the simultaneous use of a glass electrode. In this study the combination of a COMA together with a glass electrode was evaluated for measurement of esophageal oxygen tension in 5 patients. The COMA electrodes showed a mean value of 2.1 pH units higher than the glass electrodes, corresponding to a pO2 level in the esophagus of 10 kPa. As the more protracted oxygen effect on the COMA electrodes was easily recognized, especially in levels of the pH above 7.8 units, they were used for indirect evaluation of intraluminal oxygen tension in the esophagus in a further 57 patients, monitored over 24 h for gastroesophageal reflux disease. The intraluminal pO2 decreased in the supine position and with increase in age. An increase in pO2 was seen after eating and during reflux periods. The changes in pO2 are interpreted as being secondary to blood flow alterations in the esophagus.

Because aspiration pneumonia contributes significantly to morbidity and mortality in hospitalized patients, this study was undertaken to identify risk factors for morbidity and mortality associated with aspiration pneumonia. Patients with a discharge diagnosis of aspiration pneumonia in 1985 and 1990 were studied. Factors associated with death from aspiration pneumonia were: altered mental status, cerebrovascular accident, endotracheal intubation, tachycardia, and hypoxemia. Fever, cough, and unilateral infiltrates on chest radiograph were associated with survival. Attention to proper positioning of comatose patients, aggressive treatment of gastroesophageal reflux, and strict attention to endotracheal tubes and tracheostomies should decrease the morbidity and mortality associated with aspiration pneumonia.

Aspiration pneumonia due to gastroesophageal reflux is a frequent complication in ICU. The most commonly chosen method for long-term enteral access is gastrostomy and this method also reduces the risk of aspiration and shortens the hospital stay. We evaluated 31 patients in whom PEG was performed between 1997-98 in our unit. Indication of PEG was long-term ICU stay and coma which necessitate long term enteral nutrition. Mean age of our patients were 60.5((19.4). We evaluated the aspiration by clinical inspection. Aspiration and interruption of feeding was observed 1.57 ((1.43) times before PEG and 0.67 ((0.73) times after PEG. Further more positive tracheal aspirate culture were seen 3.14 ((1.95) times before PEG and 1.52 ((1.47) times after PEG.
