Ted patients with MX69 chemical information unilateral lung disease. Of the 15 patients studied, seven had pneumonia and eight atelectasis with no response to routine physicotherapy. All patients were sedated and paralyzed for the study. k electric share price forecast All patients were ventilated in the A/C mode. We performed measurements of gas exchange and respiratory system compliance and resistance (interrupter technique) with the patient supine. gas 4 weeks pregnant Immediately afterwards the patient was placed at lateral decubitus position with the involved side upwards. After 10 min at the new position, measurements were repeated. We searched for differences with positioning for the parameters measured. gas constant in atm We also tried to correlate changes in oxygenation with a score expressing the radiographic extend of lung disease on the basis of portable anterolateral X-rays. Statistical analysis was performed with t-test and Pearson correlation. PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20734244 All measurements are expressed as mean ?SEM. Results: With lateral positioning there was a statistically significant increase in PaO2/FiO2 (from 132.5 ?19.4 to 162.5 ?18.9 mmHg, P < 0.000) and PaCO2 (from 41.7 ?2.6 to 43.7 ?2.5 mmHg, P < 0.01). static electricity human body At the same time a significant decrease in compliance (from 44.9 ?3.1 to 39.4 ?2.9 l/cmH2O, P < 0.000) and an increase in resistance (from 0.223 ?0.02 to 0.255 ?0.02 cmH2O l? s, P < 0.000), were observed. PaO2/FiO2 was significantly (P < 0.01) correlated with the radiographic score (r = 0.76). gasset y ortega filosofia Conclusion: Placement in lateral decubitus positioning with the involved side upwards, results in immediate improvement of oxygenation in the majority of cases of unilateral lung disease. This improvement is correlated with the radiographic extend of disease. At the same time a statistically significant deterioration in respiratory mechanics is observed.PSurfactant phospholipids in the bronchoalveolar lavage fluid (BALF) of children who develop acute lung injury (ALI)DA Todd*, S Sebastian*, S Gupta*, O Ross*, S Watkins*, G Clarke, AD Postle, MJ Marsh* *Paediatric Intensive Care Unit, and Child Health, Southampton General Hospital, Tremona Road, Southampton SO16 6YD, UK Introduction: Children with ALI represent 5 of admissions to our Paediatric Intensive Care Unit [1]. Although there has been much research in adults with ALI, little is known about the pathophysiology in children [2]. More specifically there is a paucity of information on the pulmonary phospholipid (PL) changes during ALI children. Results: Over 9 months, 40 (8.8 ) children of 452 admissions developed ALI. Ten of 26 eligible children were enrolled in the study; six parents declined consent and 10 children were either too unstable for BALF collection or were not recruited in time. In the study group, the dipalmitoyl PC (DPPC) content in BALF decreased from control values (42.8 ?6.5 of total PC) to a minimum of 23.1 ?11.9 (P < 0.01) between days 2?, but increased to 37.8 ?4.8 pre-extubation. These changes were accompanied by reciprocal increases in the concentrations of monounsaturated PC species characteristic of inflammatory cells.Molecular species compositions of phosphatidylcholine (PC), were determined by electrospray ionisation mass spectrometry of lipid extracts of BALF supernatants. Children without any pulmonary pathology who were intubated following surgical procedures acted as controls. electricity problem in up The study was approved by the local research ethics committee.Available online http://ccforum.com/supplements/6/SPTreatment of status asthmaticus in children: is there a place for sodium b.
