background: obtaining a good sensory and motor block is the goal of performing spinal anesthesia for surgeries. the aim of this study is to compare the effect of trendelenburg position on sensory block level after spinal anesthesia with intrathecal hyperbaric bupivacine. methods: we enrolled 80 men, classified as asa i, scheduled for elective hernia repair under spinal anesthesia. participants ...

BACKGROUND It remains to be elucidated whether the Trendelenburg position increases intracranial pressure (ICP). ICP can be evaluated by measuring the sonographic optic nerve sheath diameter (ONSD). We investigated the effect of the isolated Trendelenburg position on ONSD in patients undergoing robot-assisted laparoscopic radical prostatectomy. Additionally, we evaluated the effect of the Trend...

background :although  laparoscopic   cholecystectomy  is   associated  with  less   post-operative  pain compared  to   open  cholecystectomy,  diffuse  shoulder  and  abdominal  pain  is   one    of   the    main postoperative complications in  this technique. the  aim  of this study was  to  compare the  abdominal and shoulder pain after laparoscopic cholecystectomy by  applying intra-abdomin...

Background The objective of this study was to assess the effects of 25-degree and 30-degree Trendelenburg positions on intraocular pressure (IOP) changes during robot-assisted radical prostatectomy (RARP). Materials and methods This prospective study involved a total of 30 consecutive patients undergoing RARP. All participants were randomly divided into two groups: Trendelenburg position with...

BACKGROUND The Trendelenburg position has been suggested for right internal jugular vein (RIJV) catheterization. However, this position can sometimes be functionally intolerable for chronic kidney disease patients. We conducted an ultrasound study to further investigate the efficacy of the use of the Trendelenburg position during tunneled dialysis catheter insertion via the RIJV in chronic kidn...

Central vein catheterization is a common procedure performed on patients under intensive care. The safe and successful placement of the central venous catheter depends on vein size. Although used for this purpose, the Trendelenburg position can be hazardous in some patients. The aim of this study was to compare the effects of the Trendelenburg and passive leg raising (PLR) positions on the size...

OBJECTIVE Trendelenburg positioning is a common approach used during internal jugular vein (IJV) cannulation. No evidence indicates that Trendelenburg positioning significantly increases the cross-sectional area (CSA) of the IJV in obese patients. The primary aim of this study was to determine the effectiveness of Trendelenburg positioning on the CSA of the right internal jugular vein assessed ...
