摘要: Papers p 1099 In this week's BMJ Wilson and colleagues report a randomised controlled trial in high risk surgical patients admitted to an intensive care unit at least four hours before elective operation for optimisation of cardiac output oxygen delivery >600 ml/min/m2. This pre-emptive strategy was compared with usual practice, which is monitor the cardiovascular system intraoperatively respond changes arterial filling pressures. They showed reduction mortality from 17% (95% confidence interval 8% 31%) 3% (0.7% 9%) bed use by up 40% (p 1099).1 By criteria their were risk: about third had known ischaemic heart disease half them aged over 70. finding not unexpected, question now what we should do it. Control circulation one first tutorials physiology. We teach how baroreceptors sense resulting pressure between force contracting resistance …
