Resuscitation

Questions remain about the optimal timing and method for treating ventricular fibrillation (VF) during out-of-hospital cardiac arrest, and a variety of treatment protocols are used. Detailed description of rescue shock outcomes during actual patient care under different protocols would allow rational comparison of treatment strategies. The purpose of this study is to describe rescue shock outcomes in a single system using a specific defibrillation protocol. ⋯ Witnessed collapse and an initial rhythm other than asystole were associated with an increased likelihood of rescue shock success. There is a small but real incremental gain in ROSC and ROEA from delivering three rescue shocks in rapid succession. The greater incidence of rescue shock success with later rescue shocks suggests that VF responds favorably to ongoing resuscitation.

Review Case Reports
Acute respiratory failure leading to emergency intubation: an unusual manifestation of Munchausen's syndrome.
Munchausen's syndrome is a contrived psychiatric disorder, in which patients present with an intentionally produced or feigned illness with the aim to assume the sick role and to gain medical attention. Patients may even seek the application of invasive procedures, sometimes with serious risk to life. ⋯ This case report may contribute to the awareness among emergency physicians of Munchausen's syndrome as a differential diagnosis of respiratory failure. Recognition of this psychiatric disease is not only important for correct medical diagnosis and treatment, but also essential in protecting the patients from unnecessary invasive and aggressive medical procedures.

Comparative Study
Sustained abdominal compression during CPR raises coronary perfusion pressures as much as vasopressor drugs.
This study investigated sustained abdominal compression as a means to improve coronary perfusion pressure (CPP) during cardiopulmonary resuscitation (CPR) and compared the resulting CPP augmentation with that achieved using vasopressor drugs. ⋯ During CPR noninvasive abdominal compression with the inflatable contoured cuff rapidly elevates the CPP, sustains the elevated CPP as long as the device is inflated, and is immediately and controllably reversible upon device deflation. Physical control of peripheral vascular resistance during CPR by abdominal compression has some advantages over pharmacological manipulation and deserves serious reconsideration, now that the limitations of pressor drugs during CPR have become better understood, including post-resuscitation myocardial depression and the need for intravenous access.
