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...

ent hospitals’. This is an important point. Despite using a range of concentration of ADP activator for LTA in their study (2–5 mM), when analysing agreement between LTA and modified thrombelastography (mTEG), a concentration of 5 mM was used. Chen and colleagues used a concentration of 2 mM again, extrapolating predictive values for bleeding between the two papers, in our opinion, requires cau...

متن کامل[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...
