Cardiorespiratory effects of the sitting position in neurosurgery.
The cardiorespiratory effects of raising patients from the supine to the sitting position for neurosurgery were investigated. The change caused marked decreases in cardiac index, stroke volume, PaO2 and Qs/Qt, with a significant increase in (PAO2-PaO2) and total peripheral resistance. It is concluded that patients who maintain normotension in the sitting position do not necessarily have an adeq...
متن کاملThe sitting position in neurosurgery: a critical appraisal.
The potential for serious complications after venous air embolism and successful malpractice liability claims are the principle reasons for the dramatic decline in the use of the sitting position in neurosurgical practice. Although there have been several studies substantiating the relative safety compared with the prone or park bench positions, its use will continue to decline as neurosurgeons...
متن کاملMeasuring Cardiorespiratory Information in Sitting Position Using Multiple Piezoelectric Sensors
We have been studying equipment to easily acquire cardiorespiratory information at home using piezoelectric sensors arranged on the seat surface of a chair. In our previous study, we suggested that the cardiac and respiratory components could be extracted by executing template matching using a twodimensional cross-correlation function for the signals that were obtained from the piezoelectric se...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
[A retrospective study of air embolism during neurosurgery in the sitting position].
Two patients undergoing posterior fossa exploration in the sitting position for removal of foramen magnum meningiomata suffered circulatory arrest from air embolism. Both were successfully resuscitated. The mechanism of air embolism is discussed with a review of relevant literature. The disadvantages of spontaneous ventilation are emphasized and it is recommended that controlled positive-positi...
