İnterrupted aortik ark tedavisi karmaşık bir süreçtir. Cerrahi rekonstrüksiyon genellikle myokard iskemisine neden olan kros klempleme, kalbin durdurulması ve hatta kansız operasyon sahası için derin hipotermi gerektirir.Bu yazıda, normotermik şartlarda, kalbi durdurmadan çıkan aort, proksimal desendan aort replasmanını selektif kanülasyon tüm vücut perfüzyonunu sağlayan cerrahi teknik ile teda...
BACKGROUND Ischemic preconditioning (IP) may protect the liver from ischemia-reperfusion (I-R) injury during liver resection. This study investigated the effect of IP on hepatic microcirculation (HM) and analyzed the objective parameters of the HM using laser Doppler flowmetry (LDF). METHODS We used male Wistar rats (250-280 g) that underwent normothermic, segmental liver ischemia. The animal...
BACKGROUND AND PURPOSE The purpose of the present study is to determine the effect of mild hypothermia on the synthesis of ubiquitin, an important protein for maintenance of cell viability, in the hippocampal neurons following transient cerebral ischemia. METHODS Transient ischemia was induced by occluding both common carotid arteries for 5 minutes. In experiment 1, the animals were divided i...
Hypothermia maintains the impermeability of the blood-brain barrier to proteins and, therefore, presumably the development of vasogenic brain edema after brain ischemia. We intended to determine whether mild hypothermia would have a protective effect against cytotoxic brain edema, the early stage of ischemic brain edema. Two groups of Wistar rats (37 degrees C and 35 degrees C body temperature)...
OBJECTIVE To investigate the effects of epinephrine when administered during either normothermic or therapeutic hypothermic cardiopulmonary resuscitation on postresuscitation myocardial and cerebral function and survival. DESIGN Prospective, randomized, placebo-controlled experimental study. SETTING University-affiliated animal research laboratory. SUBJECTS Thirty-two healthy male Sprague...
BACKGROUND Vascularized composite allografts, particularly hand and forearm, have limited ischemic tolerance after procurement. In bilateral hand transplantations, this demands a 2 team approach and expedited transfer of the allograft, limiting the recovery to a small geographic area. Ex situ perfusion may be an alternative allograft preservation method to extend allograft survival time. This i...
