Patients were classified as responders if volume loading induced an increase in stroke volume determined using transoesophageal echocardiography (SV-TOE) [greater than or equal to] 15% under pneumoperitoneum combined with the Trendelenburg position
, compared with that before volume loading in the same position; and as non-responders otherwise (17).
The assumption was, that by placing the patient in the Trendelenburg position
, this was also beneficial to her recovery.
Cardiopulmonary resuscitation, if required, should be started in the Trendelenburg position
until the surgeon undocks the robot and the patient is horizontal (49).
Included in this review are studies that examined intracranial hemodynamic management using head elevation, the flat supine and Trendelenburg positions
The OLP was measured in the lithotomy position, 10 minutes after assuming the Trendelenburg position
, 10 and 30 minutes after gas insufflation and 10 minutes before the completion of surgery.
Therefore, Trendelenburg position
and positive pressure ventilation are recommended.
30-180 minutes) with a steep Trendelenburg position
The Trendelenburg position
in gynaecological laparoscopic surgery further elevates airway pressure, with the displacement of the diaphragm into the thoracic cavity producing a further decrease in respiratory compliance.
Difficulty obtaining pneumoperitoneum secondary to preperitoneal fat, difficulty ventilating these women in steep Trendelenburg position
, and difficulty gaining adequate exposure during surgery are among the challenges in this patient population, she added.
We must also be aware that the Trendelenburg position
increases intrathoracic pressure, impairing venous return and accentuating the change in functional residual capacity.
The aim of this study was to evaluate the influence of passive leg elevation and Trendelenburg position
on the cross-sectional area (CSA) of the internal jugular (IJ) and subclavian veins (SCV).
The intra-abdominal pressure is strictly limited to 12 mm Hg, and all patients are placed in a maximally tolerated Trendelenburg position
