ABSTRACT The effect of position on the spread and the onset time of epidural anesthesia has not been well documented. This study is undertaken to assess the effect of modified trendelenburg position on the spread of epidural anesthesia for cesarean section. 739 parturients were undergone epidural anesthesia for elective or emergent sesarean section. They were divided into 2 groups in a...

BACKGROUND Unlike the right internal jugular vein (RIJV), there is a paucity of data regarding the effect of the Trendelenburg position on the left internal jugular vein (LIJV). The purpose of this study is to investigate the cross-sectional area (CSA) of the LIJV and RIJV and their response to the Trendelenburg position using two-dimensional ultrasound in adult subjects. METHODS This study e...

OBJECTIVES To evaluate the relationship between Trendelenburg tilt and internal jugular vein (IJV) diameter, and to examine any cumulative effects of tilt on the IJV diameter. METHODS Using a tilt table, healthy volunteers were randomised to Trendelenburg tilts of 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees. Ultrasound was used to measure and record the lateral diameter of ...

Background. The use of echocardiography in intensive care settings impacts decision making. A prerequisite for the use of echocardiography is relative resistance to changes in volume status and levels of positive pressure ventilation (PPV). Studies on indices of diastolic function report conflicting results with regard to dependence on volume status. Evidence is scarce on PPV. Methods. Ten heal...

BACKGROUND Different tests are used in order to classify women with pelvic girdle pain (PGP). One limitation of the tests is that they need to be performed by an examiner. Self-administered tests have previously been described and evaluated by women who performed the tests directly before the examiner performed the original tests. Thus, an evaluation of the self-administered tests performed in ...

OBJECTIVES (1) To determine the validity of current recommendations for direct arterial BP measurement that suggest that the transducer (zeroed to atmosphere) be placed level with the catheter access regardless of subject positioning: and (2) to investigate the effect of transducer level, catheter access site, and subject positioning on direct arterial BP measurement. DESIGN Prospective, cont...

BACKGROUND The steep (40 degrees ) Trendelenburg position optimizes surgical exposure during robotic prostatectomy. The goal of the current study was to investigate the combined effect of this position and CO(2) pneumoperitoneum on cardiovascular, cerebrovascular, and respiratory homeostasis during these procedures. METHODS Physiological data were recorded during the whole surgical procedure ...

A short cut review was carried out to establish whether the use of the Trendelenburg position improves the rate of cardioversion in supraventricular tachycardias (SVTs). 54 papers were found of which 3 presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of the...
