Mobile emergency (surgical) hospital: Development and application in medical relief of "4.20" Lushan earthquake in Sichuan Province, China.

In the 21st century, natural disasters and emergencies occur frequently worldwide, which leads to the loss of hundreds of thousands of lives as well as the direct and indirect economic losses. China has a vast territory frequently struck by natural disasters. However, the reality is not optimistic. Poor organization and management during the rescue actions, the lack of large-scale, systematic medical rescue equipment were all great barriers to the outcomes. Mobile hospitals are expected to provide better health care. We were inspired by the concept of mobile hospital. Chongqing Emergency Medical Center, has set up trauma care system since 1988, in which prehospital care, intensive care, and in-hospital treatment is fully integrated. As a major advantage, such a system provided assurance of "golden hour" rescue treatment. Providing mobile intensive care and prehospital surgical service for severe trauma patients could reduce mortality significantly. Based on the civilian experiences in Chongqing Emergency Medical Center, the mobile emergency (surgical) hospital was developed.

[Correlation between lung volume and the severity of obstructive sleep apnea hypopnea syndrome in obese patients].

OBJECTIVE: To examine the relationship between the severity of obstructive sleep apnea hypopnea syndrome (OSAHS), lung volume and obesity. METHODS: The study included 60 adult male obese patients with OSAHS determined by overnight polysomnogram (PSG) using American Academy of Sleep Medicine-defined criteria. Lung volume measurements were made in maximum vital capacity (VCmax), forced vital capacity (FVC), maximum voluntary ventilation (MVV), functional residual capacity (FRC) and total lung capacity (TLC). RESULTS: The aponea hypopnea index (AHI) were negatively correlated with FVC, MVV, VCmax (r were -0.533, -0.276 and -0.575, P < 0.01 or P < 0.05). But the lowest arterial oxygen saturation (LSaO2) and the mean arterial oxygen saturation (MSaO2) were positively correlated with FVC, MVV and VCmax (r were 0.299, 0.435, 0.412, and 0.344, 0.474, 0.457, P < 0.01 or P < 0.05). The body mass index (BMI) were positively correlated with AHI (r = 0.728, r(2) = 0.530, P < 0.01). The FVC, MVV, VCmax, LSaO2 and MSaO2 varied inversely with BMI. FRC and TLC had no relation with AHI, LSaO2, MSaO2 and BMI. CONCLUSIONS: There are significant correlations among obesity, dynamic lung volume and OSAHS severity. This result suggests that changes in dynamic lung volume may play an important role in the pathogenesis of OSAHS in obese patients.
