Intervention to avoid the prone sleeping position during infancy has occurred in various countries after evidence that it increases the risk of sudden infant death syndrome (SIDS). This study examined cohort data to determine if correlates of the prone position differed by period of birth, before intervention (1 May 1988 to 30 April 1991) compared with after intervention (1 May 1991 to 30 April...

OBJECTIVE The vulnerability of prematurely born infants to sudden infant death syndrome (SIDS) in the prone position might be explained by a reduced ability to respond to a stress, such as hypercarbia, in that position; our objective, therefore, was to further explore the influence of position on the response to a stress. WORKING HYPOTHESIS The ability of prematurely born infants to respond t...

UNLABELLED By compressing the abdomen and restricting chest wall movement, the prone position compromises pulmonary compliance. For spine surgery, placing the anesthetized patient into the prone position increases the risk of improper ventilation. In this study, we tested the hypothesis that the compromise in pulmonary compliance is related to the patient's body habitus and the surgical frame u...

BACKGROUND To our knowledge there is no report in the literature on measurements of vertebral rotation with low-dose computed tomography (CT) in prone position. AIMS To describe and test the reliability of this new method, compare it with other methods in use and evaluate the influence of body position on the degree of vertebral rotation measured by different radiological methods. STUDY DES...

The fact that operating a patient in the supine position is easier than in a prone position is rather intuitive: apart from PCNL and, obviously, spinal surgery, there is no surgery of retroperitoneal organs performed in the prone position. So, why is it that nowadays PCNL is performed in the supine position only in 20% of cases worldwide? [1]. Indeed, the prone position was adopted in the pione...

background:infant mortality is often used as a standard measure of a population’s health. until cause of sudden infant death syndrome is unknown (sids), the best strategy to decrease sids, is programming to decrease facing with risk factors. the aim of this study was to find the sids risk factors among families during their child care in iran. the study is the first in iran to examine the risk ...
