Resuscitation
-
We assessed the familiarity of the general public with automated external defibrillators (AEDs) and their willingness to use them. ⋯ Although a substantial number of people in this setting were willing to use an AED, education regarding legal liability and proper use of the machines increased the reported likelihood of use. Further public education may be necessary to provide optimally effective public access defibrillation programs.

Research in patients with life-threatening illness such as cardiac arrest is challenging since they can not consent. The Food and Drug Administration addressed research under emergency conditions by publishing new criteria for exception from informed consent in 1996. We systematically reviewed randomized trials over a 10-year period to assess the impact of these regulations. ⋯ Fewer American cardiac arrest trials were published during the last decade, when federal consent requirements changed. Regulatory requirements for clinical trials may inhibit improvements in care and threaten public health.

Case Reports
Successful thrombolysis after pulmonary embolectomy for persistent massive postoperative pulmonary embolism.
Massive postoperative pulmonary embolism (PE) is associated with a poor prognosis in patients presenting with haemodynamic instability. Since recent surgery is a commonly accepted contraindication for thrombolytic therapy, pulmonary embolectomy is an appropriate therapeutic approach in these patients. ⋯ During and after thrombolysis, no bleeding complications occurred. We conclude that low-dose thrombolysis for PE may be considered even in patients who have recently undergone major thoracic and abdominal surgery if embolectomy and continued intravenous heparin have failed to be successful and life-threatening symptoms of PE persist.

To determine whether antithrombin (AT) administration during cardiopulmonary resuscitation (CPR) increased cerebral circulation and reduced reperfusion injury. ⋯ In this experimental model of CPR, AT administration did not increase cerebral circulation or reduce reperfusion injury after ROSC.
-
To analyze the relationship between stress hormones (arginine vasopressin (ADH), adrenocorticotropic hormone (ACTH) and cortisol and the outcome of patients resuscitated after cardiopulmonary arrest (CPA). ⋯ We concluded that the serum cortisol levels were significantly higher in survivors than in non-survivors resuscitated after CPA.
