Filter by:By observing the changes of Central venous-arterial partial pressure difference of carbon dioxide [P (v-a) CO2] in liquid resuscitation during early escharectomy in patients with large-scale burns, We investigate the effect of P (v-a) CO2 on postoperative tissue perfusion and oxygenation in order to seek a more effective intergrated target plan of liquid resuscitation for burn patients.
The idea of this work came during a carotid surgery, when we noticed a respiratory variation of the right internal jugular vein. Also, because of the interest of evaluating the preload dependence during an intervention or reanimation where it is difficult to access the other monitoring methods . The aim of the study was to test the hypothesis that respiratory changes in right internal jugular vein diameter are similar to respiratory changes in superior and inferior vena cava in mechanically ventilated patients and therefore help to predict fluid responsiveness.
Two approaches such as ultrasound (US)-guided and prelocation techniques are possible when the internal jugular vein cannulation is attempted with US. This study is a clinical trial that compares the success rates of both techniques and shows the non-inferiority of the prelocation technique. However, during prelocation technique, rotated screen of the US is used instead of original screen. The angle of rotation is determined by the degree of rotation of US probe where an accelerometer is attached.
Two approaches are possible when the first finder needle attempt of the internal jugular vein cannulation fails; the needle can be turned slightly laterally or the puncture point can be moved slightly medially. This study is an ultrasonographic stimulation study to evaluate the success rate of turning the needle laterally and moving the puncture point medially, and to determine the proper angle or distance for the second try of internal jugular vein cannulation.
