Beta-adrenoceptor-mediated responsiveness of human internal mammary artery
The internal mammary artery (IMA) is currently the preferred conduit for myocardial revascularization. However, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. The mechanism of spasm has not been clearly defined. Since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...
متن کاملThe effect of Benson relaxation technique on sleep quality after coronary artery bypass graft surgery
Introduction: One of the common problems of patients after open heart surgery is sleep disturbance. The aim of this study was to investigate the effect of benson relaxation on sleep quality after coronary artery bypass graft. Materials and Methods: In this randomized controlled trial, 80 patients allocated to the benson relaxation and control groups. For the intervention group, Benson's relaxa...

متن کاملTemporary clamping of external carotid artery in convexity, parasagittal and temporal base meningioma.
AIM The management of intraoperative bleeding during removal of a large hyper vascular meningioma is crucial for safe and efficient surgery. Preoperative embolization of meningioma is the best way to reduce vascularity of meningiomas but this technique is not readily available, costly and has its own limitations. The study is aimed to evaluate the use of temporary clamping of external carotid a...
متن کاملKidney pressures after temporary renal artery occlusion in the rat.
Acute kidney failure was produced in the anesthetized rat by 1 h of complete renal artery occlusion. Kidney function was studied either immediately after release of the occlusion or 1 day later using clearance, micropuncture, histological, and nephron dissection techniques. Polyfructosan clearance was decreased to 5% of normal after temporary occlusion. Proximal tubular pressure (PTP) averaged ...
