Abstract

Objective: The laser speckle contrast imaging (LSCI) system is a method to evaluate microcirculation. The primary aim of our study is to evaluate the relationship between LSCI and perfusion markers in coronary artery bypass grafting (CABG). Our second aim is to investigate the relationship between LSCI and extubation time in the intensive care unit. Patients and Methods: Fifteen patients aged 43-80 years who will undergo on-pump CABG were included in the prospective study. Mean arterial pressure (mmHg), heart rate (min-1), PO2 (mmHg), PCO2 (mmHg) and lactate (mmol/L) levels were measured preinduction, post-induction, 10th minute of the extracorporeal circulation, post-crossclamp, and post-operatively. At the same time points, LSCI values from the skin were measured and recorded. The intubation times of the patients were also recorded. Results: There was no significant change in systemic tissue perfusion markers (P>0.05). LSCI perfusion values decreased significantly from induction and remained low until the end of surgery (P

利用激光散斑造影技术监测体外循环过程中的组织灌注

目的:激光散斑对比成像(LSCI)系统是一种评价微循环的方法。我们研究的主要目的目的探讨冠状动脉旁路移植术(CABG)中LSCI与灌注指标的关系。我们的第二个目标是:探讨重症监护病房LSCI与拔管时间的关系。患者和方法:前瞻性研究包括15例43-80岁将接受无泵搭桥的患者。诱导前测量平均动脉压(mmHg)、心率(min-1)、PO2 (mmHg)、PCO2 (mmHg)和乳酸(mmol/L)水平，诱导后，体外循环第10分钟，十字夹后，术后。同时点，测量并记录皮肤LSCI值。同时记录患者插管次数。结果:两组全身组织灌注指标无明显变化(P>0.05)。LSCI灌注值明显降低从诱导开始并一直保持在低水平直到手术结束(P
