We have devised a method of measuring pulmonary capillary blood flow (Qpc eff) suitable for infants with idiopathic respiratory distress syndrome (IRDS). The uptake of nitrous oxide is measured during a 40-second period of rebreathing 40% nitrous oxide in oxygen from a 40- to 80-ml bag. The rate of uptake of nitrous oxide is divided by the solubility in cord blood and the mean alveolar concentration to give Qpc eff. We studied 14 preterm infants, 7 hours to 14 days of age, on 73 occasions; nine had classical IRDS and five were healthy preterm infants (controls). During the first five days of life Qpc eff was significantly lower in infants with IRDS than in the control infants, 106 ml/kg/min compared with 177 ml/kg/min (P < 0.001). Qpc eff was not related to arterial Po2, Pco2, or pH but was inversely related to the inspired oxygen concentration needed to keep the arterial Po2 within normal limits (P < 0.02). Qpc eff showed a highly significant increase with age in infants with IRDS (P < 0.001). This method provides a reasonably rapid, safe and noninvasive technique for estimating effective pulmonary blood flow in sick infants.

Purpose: In this study, we aimed to compare cardiac output, echocardiographic pulmonary velocity-time integral, and end-tidal carbon dioxide values before and after the passive leg raising maneuver in healthy volunteers. Methods: The Ethical Commission approved the study. A total of 36 volunteers were included after signed informed consent in our study. After 12 h of fasting, vital signs, cardiac output, pulmonary velocity-time integral, and end-tidal carbon dioxide were measured when the participants were lying supine. Then, participants’ legs were elevated to 45° passively, and all measurements were repeated. Pulmonary velocity-time integral was obtained in parasternal short-axis view with the aid of pulse Doppler. Pulmonary root measurements were recorded. Echocardiographic stroke volume and cardiac output were calculated. The differences between values of cardiac output, pulmonary velocity-time integral, and end-tidal carbon dioxide before and after passive leg raising were statistically compared. The level of significance was accepted as p < 0.05. Results: Significant differences were found between pre- and post-passive leg raising values of these three measurements. The effect of passive leg raising on pulmonary velocity-time integral measurements was greater. The change in end-tidal carbon dioxide was not correlated with either cardiac output or pulmonary velocity-time integral alteration. Conclusion: Our results showed that measurement of pulmonary velocity-time integral changes after passive leg raising is a more useful bedside method to predict fluid responsiveness than measurement of end-tidal carbon dioxide and cardiac output alteration.

BACKGROUND: Endoscopic evaluation of swallowing (EES) is not commonly used by gastroenterologists to evaluate swallowing in patients with dysphagia.OBJECTIVE: To use transnasal endoscopy to identify factors predicting successful or failed swallowing of pureed foods in elderly patients with dysphagia.METHODS: EES of pureed foods was performed by a gastroenterologist using a small-calibre transnasal endoscope. Factors related to successful versus unsuccessful swallowing of pureed foods were analyzed with regard to age, comorbid diseases, swallowing activity, saliva pooling, vallecular residues, pharyngeal residues and airway penetration/aspiration. Unsuccessful swallowing was defined in patients who could not eat pureed foods at bedside during hospitalization. Logistic regression analysis was used to identify independent predictors of swallowing of pureed foods.RESULTS: During a six-year period, 458 consecutive patients (mean age 80 years [range 39 to 97 years]) were considered for the study, including 285 (62%) men. Saliva pooling, vallecular residues, pharyngeal residues and penetration/aspiration were found in 240 (52%), 73 (16%), 226 (49%) and 232 patients (51%), respectively. Overall, 247 patients (54%) failed to swallow pureed foods. Multivariate logistic regression analysis demonstrated that the presence of pharyngeal residues (OR 6.0) and saliva pooling (OR 4.6) occurred significantly more frequently in patients who failed to swallow pureed foods.CONCLUSIONS: Pharyngeal residues and saliva pooling predicted impaired swallowing of pureed foods. Transnasal EES performed by a gastroenterologist provided a unique bedside method of assessing the ability to swallow pureed foods in elderly patients with dysphagia.
