BACKGROUND Different tidal volume (TV) settings during mechanical ventilation alter intrathoracic blood volume, and these changes could alter central venous pressure and the cross sectional area (CSA) of the right internal jugular vein (RIJV). The aim of this study was to determine the optimal TV for maximizing the CSA of the RIJV in the supine and Trendelenburg positions in anesthetized patien...

Robot-assisted gynecologic surgery is performed with a pneumoperitoneum and prolonged maximum Trendelenburg position which can result in adverse physiologic effects. The purpose of this study was to assess the feasibility of robot-assisted gynecologic oncology procedures and to identify anesthesia-related peri-operative adverse events. This is a case series performed on the first 133 patients w...

BACKGROUND AND OBJECTIVES Pneumoperitoneum during laparoscopy can produce changes in intraocular pressure (IOP) that may be influenced by several factors. In this study, we investigated changes in IOP during laparoscopy with different positioning. METHODS We recruited adult patients without eye disease scheduled to undergo laparoscopic operation requiring a reverse Trendelenburg tilt (rTr; gr...

During robot-assisted laparoscopic prostatectomy, specific physiological conditions such as carbon dioxide insufflation and the steep Trendelenburg position can alter the cardiac workload and cerebral hemodynamics. Inadequate arterial blood pressure is associated with hypoperfusion, organ damage, and poor outcomes. Dynamic arterial elastance (Ea) has been proposed to be a useful index of fluid ...

We have assessed the potential for myocardial ischaemia during laparoscopic cholecystectomy in 16 otherwise healthy patients. Continuous ambulatory ECG monitoring was commenced 12 h before operation and continued for 24 h after operation. The neuroendocrine stress response was assessed by measuring plasma concentrations of adrenaline and noradrenaline, human growth hormone, cortisol, renin and ...

Abstract Background Pneumothorax associated with a steep head-down position in vaginal hysterectomy surgery is rare but can cause life-threatening complications. Case presentation We report case of female patient no obvious lung pathology who suffered intraoperative pneumothorax prolonged Trendelenburg position. To the best our knowledge, this first well-documented association. A 53-year-old fe...

A complete knot occurred in a 7F flow-directed balloon catheter inserted through the right internal jugular vein. The patient was intubated and placed under positive pressure ventilation. After gaining surgical exposure of the venipuncture site, a purse-string of Prolene 4--0 suture was placed around it. The patient was placed in the Trendelenburg position and the knotted catheter withdrawn, wh...
