Objective： The laryngeal mask airway （LMA） is an established way for airway control during spontaneous ventila- tion. Its ability to deliver positive pressure ventilation without leakage especially in low flow states is still controversy. The aim of this study is to test the possibility of using LMA in pediatric closed circuit controlled ventilation, and to find out the optimum cuff volume to perform closed system ventilation. Methods： Twenty children scheduled for elective surgeries were enrolled in a crossover study. Laryngeal mask airway was used. In stage I, the cuff was inflated with the maximum volume of air as rec- ommended by the manufacturers. Adjustment of volume of air inflated into the LMA cuff to the minimum volume to obtain the effective seal was done at stage II. The leak pressure, intracuff pressure and the leak volume were measured in both stages. Results： The cuff filling volume was significantly lower compared to the maximum cuff inflation volume in stage I. Leakage values showed significantly less values in stage II of the study with smaller cuff inflation volumes. The airway leakage pressure was significantly lower in stage fl in comparison to stage I. Cuff inflation pressure in stage I showed marked elevation which dropped significantly after adjustment of cuff volume in stage I1. Conclusion： Laryngeal mask airway is an effective tool to provide closed circuit controlled ventilation in pediatrics. Inflation of the cuff by the minimum volume of air needed to reach the just sealing pressure is suggested to minimize the leakage volume.

BACKGROUND Little is known about inflammatory bowel disease(IBD)burden and its impact on bone mineral density(BMD)among adult patients in Saudi *** the best of our knowledge,our study is the only study to give an update about this health problem in adult Saudi patients with *** is a great risk factor for reduced BMD due to its associated chronic inflammation,malabsorption,weight loss and medication side ***,screening for reduced BMD among patients with IBD is of utmost importance to curb and control anticipated morbidity and mortality among those *** To assess the relationship between IBD and BMD in a sample of adult Saudi patients with *** Ninety adult patients with IBD-62 Crohn’s disease(CD)and 28 ulcerative colitis(UC)-were recruited from King Fahad Specialist Hospital gastroenterology clinics in Buraidah,*** enrolled patients were interviewed for their demographic information and for IBD-and BMD-related clinical *** patients had the necessary laboratory markers and dual-energy x-ray absorptiometry scans to evaluate their BMD *** were divided into two groups(CD and UC)to explore their clinical characteristics and possible risk factors for reduced *** The CD group was significantly more prone to osteopenia and osteoporosis compared to the UC group;44%of the CD patients had normal BMD,19%had osteopenia,and 37%had osteoporosis,while 78%of the UC patients had normal BMD,7%had osteopenia,and 25%had osteoporosis(P valuez-score(r=0.77,Pz-score(r=0.85,Pz-score(r=0.82,Pz-score(r=0.80,P<0.05).The ROC-curve showed that low BMI could predict the lowest t-score in the CD group with the best cut-off value at≤23.43(m/kg2);area
