This study evaluated the effect of passive leg elevation and Trendelenburg position
on the CSA of the IJV or the SCV using ultrasound imaging.
Sasada currently uses a minimum Trendelenburg position
and an iPad when performing robotic-assisted hysterectomy and other pelvic surgeries, but not in all cases, as some OR beds have built-in clinometers.
The pneumoperitoneum in combination with the Trendelenburg position
resulted in inward movement of the ETT tip to the carina in 99% of the patients and [D.sub.TC1] was shorter than [D.sub.TC0] by 1.4 cm on average and 2.2 cm maximum.
However, the reduction in venous outflow from the head caused by pneumoperitoneum in a prolonged, exaggerated Trendelenburg position
may be severe enough to cause laryngeal oedema, as was seen in Case 1.
The other is that we might not count all bleeding during laparoscopic surgery because aspirating the blood from the upper abdomen in Trendelenburg position
is not always easy and sometimes skipped if the bleeding seemed not that much.

Comparison of volume-controlled ventilation and pressure-controlled ventilation volume guaranteed during laparoscopic surgery in Trendelenburg position

We would like to emphasize on the importance of using less traumatic methods instead of an adhesive tape to fix the tube on patients with spider angioma or facial telangiectasia as well as indicate the possible mechanical harms of the Trendelenburg position
during laparoscopic procedures in order to avoid similarly disheartening situations, albeit of no clinical importance.

The patient was positioned supine with bed tilted head-down (Trendelenburg position
) and rolled leftward.
The patient was then placed in a supine, 20-degree Trendelenburg position
. However, radiology reported that the mass did not change its place during movements; a free-floating white colored mass was observed in the small intestine above the bladder during laparoscopy (Figure 1(d)).
Proper management of a vasovagal reaction involves termination of the noxious stimulus, intravenous volume replacement, the Trendelenburg position
, and administration of atropine (0.6 to 1 mg intravenously) .
