Filter by:Based on the relative shortage of ophthalmic surgeons in China, the long micromanipulation cycle and the existing micromanipulation training methods have their own limitations, such as traditional operating in porcine eyes limited to synchronous guidance and evaluation, while surgical simulators are very different for the simulation of real tissues, and the price is expensive and easy to lose. Based on these, the development of a digital training system, that is, based on traditional micromanipulation platforms such as animal tissue, physical microscopic instruments supplemented by synchronous surgical guidance and evaluation, can combine the advantages of traditional training and simulator, so as to improve the efficiency of ophthalmic surgeon training, and also provide digital ideas for other disciplines based on traditionally surgical teaching.
By comparison of two different protocols with diverse fluid/ catecholamine administration limits (fluid restriction vs. catecholamine restriction with target systolic blood pressure > 100 mmHg) the investigators would like to reveal the impact of intraoperative blood pressure management on the survival rate of free deep inferior epigastric artery flaps for breast reconstruction.
Prostaglandin E1 (PGE1 )has been shown to have vasodilatation and anti-thrombosis effects, so it is used by some surgeons after microsurgery to keep the patency of the anastomosed small vessels. However, PGE 1 may also causes some complications, like pleural effusion or deep vein thrombosis. Therefore, it remains uncertain whether a routine use of PGE 1 after head and neck microsurgery is justified. We aim to test the hypothesis that PGE 1 increases postoperative vessel patency rate in patients undergoing head and neck microsurgery, with a comparable complication rate as the control group.
