STUDY OBJECTIVE To determine the cephalocaudal relationship among the umbilicus, aortic bifurcation, and iliac vessels by direct measurement during laparoscopy. DESIGN Prospective, consecutive study (Canadian Task Force classification II-1). SETTING Tertiary referral center. PATIENTS Ninety-seven women undergoing operative laparoscopy. INTERVENTIONS The distance from the aortic bifurcat...

We investigated the influence of pneumoperitoneum#(PP) and postural change under inhalation anesthesia with isoflurane, which is routinely used in dogs, on the cardiovascular and respiratory systems. As test animals, 6 adult beagles were used. To induce anesthesia, atropine, butorphanol and propofol were intravenously injected. Anesthesia was maintained with 1.3 MAC (1.7%) isoflurane. The follo...

Background/Purpose: The right internal jugular vein (RIJV) is the most commonly accessed central venous site in the cardiac operating room. The Trendelenburg position is frequently used to increase the cross-sectional area (CSA) of the RIJV to facilitate its cannulation. However, the extent of change of RIJV CSA in response to Trendelenburg positioning in anesthetized patients and its predictiv...

Background Robotic pelvic surgeries require steep Trendelenburg position which may result in rise in intraocular pressure (IOP). Aim The aim of this study was to compare the changes that occur in IOP during robotic pelvic surgeries in steep Trendelenburg position with a restrictive intravenous fluid administration. Settings and Design This prospective observational study was conducted in a ...

AIM The aim of this work was to compare the reduction in edema obtained in the conservative treatment of phlebopathies after resting and after performing a muscle exercise program in the Trendelenburg position. METHODS Twenty-eight limbs of 24 patients with venous edema of distinct etiologies and classified as between C3 and C5 using CEAP classification. Volumetric evaluation by water displac...

HYPOTHESIS Large-bore subclavian intravenous access is important during trauma resuscitation and to provide central access in the intensive care unit. Controversy exists as to the patient position that best facilitates the insertion of this line. Duplex scanning of the subclavian vein in different body positions may help define which provides the largest vein size and distance from the clavicle...

We have measured cardiovascular changes associated with insufflation of carbon dioxide and the reverse Trendelenburg position during laparoscopic cholecystectomy, using transoesophageal echocardiography in 13 healthy patients. End-tidal carbon dioxide values increased after insufflation of carbon dioxide, with values significantly (P < 0.05) increased after lateral tilt positioning. Creation of...
