Does fast-tracking increase the readmission rate after pulmonary resection? A case-matched study.
The most recent evolution of patient management after thoracic surgery implies the concept of fast-tracking. Since 2008, our unit has implemented a programme based on clinical protocols and standardized pathways of care aimed to reduce the postoperative stay after major lung resection. The objective of this study was to verify the safety of this policy by monitoring the patient readmission rate. ⋯ In our experience, the implementation of a fast-tracking program after pulmonary lobectomy was very effective and safe. It led to a postoperative reduction of hospital stay without an increase in the readmission rate.

Studies of isolated global brain ischaemia: III. Influence of pulsatile flow during cerebral perfusion and its link to consistent full neurological recovery with controlled reperfusion following 30 min of global brain ischaemia.
Brain damage is universal in the rare survivor of unwitnessed cardiac arrest. Non-pulsatile-controlled cerebral reperfusion offsets this damage, but may simultaneously cause brain oedema when delivered at the required the high mean perfusion pressure. This study analyses pulsatile perfusion first in control pigs and then using controlled reperfusion after prolonged normothermic brain ischaemia (simulating unwitnessed arrest) to determine if it might provide a better method of delivery for brain reperfusion. ⋯ Pulsatile perfusion lowers cerebral vascular resistance and improves global O(2) uptake to potentially offset post-ischaemic oedema following high-pressure reperfusion. The irreversible functional and anatomic damage that followed uncontrolled reperfusion after a 30-min warm global brain ischaemia interval was reversed by pulsatile-controlled reperfusion, as its delivery resulted in consistent near complete neurological recovery and absent brain infarction.

Practice GuidelineEACTS guidelines for the use of patient safety checklists.
The Safety Checklist concept has been an integral part of many industries that face high-complexity tasks for many decades and in industries such as aviation and engineering checklists have evolved from their very inception. Investigations of the causes of surgical deaths around the world have repeatedly pointed to medical errors that could be prevented as an important cause of death and disability. As a result, the World Health Organisation developed and evaluated a three-stage surgical checklist in 2007 demonstrating that complications were significantly reduced, including surgical infection rates and even mortality. ⋯ A key factor in the successful implementation of a surgical checklist is engagement of the staff implementing the checklist. In surgical specialties such as our own it was quickly seen that there were many important omissions in the generic checklist that did not cover issues particular to our specialty, and thus the European Association for Cardio-Thoracic Surgery embarked on a process to create a version of the checklist that might be more appropriate and specific to cardiothoracic surgery, including checks on preparations for excessive bleeding, perfusion arrangements and ICU preparations, for example. The guideline presented here summarizes the evidence for the surgical checklist and also goes through in detail the changes recommended for our specialty.

ReviewStudies of isolated global brain ischaemia: I. Overview of irreversible brain injury and evolution of a new concept - redefining the time of brain death.
Despite advanced cardiac life support (ACLS), the mortality from sudden death after cardiac arrest is 85-95%, and becomes nearly 100% if ischaemia is prolonged, as occurs following unwitnessed arrest. Moreover, 33-50% of survivors following ACLS after witnessed arrest develop significant neurological dysfunction, and this rises to nearly 100% in the rare survivors of unwitnessed arrest. Although, whole body (cardiac) survival improves to 30% following recent use of emergency cardiopulmonary bypass, sustained neurological dysfunction remains a devastating and unresolved problem. ⋯ This review, and the subsequent three studies will describe the evolution of the concept that controlled reperfusion will restore neurological function to the brain following prolonged (30 min) ischaemia. To provide a familiarity and rationale for these studies, this overview reviews the background and current treatment of sudden death, the concepts of controlled reperfusion, recent studies in the brain during whole body ischaemia, and then summarizes the three papers in this series on a new brain ischaemia model that endorses our hypothesis that controlled reperfusion allows complete neurological recovery following 30 min of normothermic global brain ischaemia. These findings may introduce innovative management approaches for sudden death, and perhaps stroke, because the brain is completely salvageable following ischaemic times thought previously to produce infarction.
