conclusions continuous portal triade clamping (the pringle maneuver) during liver ischemia (30 and 45 minutes) in rabbits resulted in no ischemic change. increasing time of clamping to 30 minutes was safe in intermittent pringle maneuver. materials and methods in an experimental study, 20 new-zealand white rabbits were selected. in laparotomy, a blunt dissector was passed through the foramen of...

background :although  laparoscopic   cholecystectomy  is   associated  with  less   post-operative  pain compared  to   open  cholecystectomy,  diffuse  shoulder  and  abdominal  pain  is   one    of   the    main postoperative complications in  this technique. the  aim  of this study was  to  compare the  abdominal and shoulder pain after laparoscopic cholecystectomy by  applying intra-abdomin...

Conventional magnetic attitude control methodologies require several orbital periods to accomplish the required attitude maneuvers due to the existence of an uncontrollable axis, namely the local Earth’s magnetic field vector. Since in some attitude maneuver missions the elapsed time is of critical importance, those time-consuming controllers are not satisfactory and we need a much faster contr...

in order to determine the effect of valsalva maneuver and head rotation on the internal jugular vein (ijv) diameter and cross-sectional area and overlap with the carotid artery (ca) and find the best technique for safe cannulation of the ijv and decrease the risk of ca puncture, the diameter of both the ijv and the ca and percentage of overlap between the two vessels and cross-sectional area of...

A computer assisted apparatus for the continuous measurement of azygos blood flow is described. The system was validated in vitro and changes in flow which occur with respiration and Valsalva manoeuvre are illustrated. This apparatus allows real time inspection of flow values which enables changes in flow over short periods to be readily studied.
