Respiratory effects of prolonged Trendelenburg position.
The Trendelenburg position has been severely criticized (Inglis and Brooke, 1956; Swain, 1960) but is still popular for pelvic surgery. One of the main complaints about this position is that it reduces ventilation as a result of pressure by the abdominal contents upon the diaphragm. This, of course, applies only to patients breaching spontaneously, because, if artificial ventilation is used, th...
متن کاملEffects of prone and reverse trendelenburg positioning on ocular parameters.
BACKGROUND : In a pilot study of awake volunteers, intraocular pressure (IOP), choroid layer thickness, and optic nerve diameter were shown to increase in the prone position over 5 h with a nonsignificant trend of attenuation using a 4-degree increase of table inclination. These effects have previously not been isolated from anesthetic and fluid administration over a prolonged period, using an ...
متن کاملCardiovascular effects of tramadol in dogs anesthetized with sevoflurane.
Cardiovascular effects of tramadol were evaluated in dogs anesthetized with sevoflurane. Six beagle dogs were anesthetized twice at 7 days interval. The minimum alveolar concentration (MAC) of sevoflurane was earlier determined in each dog. The dogs were then anesthetized with sevoflurane at 1.3 times of predetermined individual MAC and cardiovascular parameters were evaluated before (baseline)...
متن کاملUse of the Trendelenburg Position in the Porcine Model Improves Carotid Flow During Cardiopulmonary Resuscitation
BACKGROUND Cardiopulmonary resuscitation (CPR) is now widely used as a treatment for ventricular fibrillation, though numerous studies have shown the outcome of standard CPR to be dismal. Alternative methods of CPR, including interposed abdominal compression, constant aortic occlusion, and the use of intrathoracic pressure regulator, have been shown to increase cardiac output and affect the mor...
متن کاملIntraocular Pressure Changes during Laparoscopic Surgery in Trendelenburg Position in Patients Anesthetized with Propofol-based Total Intravenous Anesthesia Compared to Sevoflurane Anesthesia: A Comparative Study
Background Intraocular pressure (IOP) is increased during laparoscopic surgery with Trendelenburg position and may contribute to deleterious effects on optic nerve in susceptible patients. Aims The primary objective of this study is to compare the effects of propofol-based total intravenous anesthesia (TIVA) with those of sevoflurane anesthesia on IOP in patients undergoing lower abdominal la...
