Clinical Trial
Predictors of successful at-home chemical cardioversion in new-onset atrial fibrillation.
Prehospital treatment of new-onset supraventricular arrhythmias can be attempted by physician-staffed mobile intensive care units to decrease the hospitalization rate and expense. Identification of patients suitable for at-home pharmacological treatment may help in the triage of patients with new-onset atrial fibrillation (AF). In the present investigation, the value of several clinical variables to predict the success of pharmacological at-home cardioversion was tested. ⋯ By multivariate analysis, only sex and the drug employed for treatment (positive relation for propafenone and bunaftine, negative for amiodarone, digoxin and verapamil) were significant predictors of the outcome of MCCU intervention. Our results suggest that patients with new-onset (less than 24 h) AF with or without underlying heart disease whose main complaint is palpitation can be successfully cardioverted at home with a class IC drug (propafenone). Patients with acute coronary syndromes or left ventricular failure are good candidates for elective cardioversion after hospitalization.

Posthypoxic myoclonus (Lance-Adams' syndrome) is a rare complication of cardiorespiratory arrest. It has a better prognosis than other movement disorders secondary to brain ischaemia. ⋯ The origin of the myoclonus was probably subcortical, and it improved with clonazepam 2 mg t.i.d. We emphasize that early diagnosis is necessary in intensive care units in order to avoid misinterpretation of this syndrome and to start appropriate treatment.

Without early access to the emergency medical services (EMS) system, the chances of surviving an out-of-hospital cardiopulmonary arrest (CPA) are poor. The aim of this study was to evaluate this first link in the chain of survival in Ghent. Therefore, we reviewed the data from the registry on all CPA cases treated by our mobile intensive care unit (MICU) and the tape recordings from the local EMS dispatch centre of 100 consecutive non-traumatic CPA cases that occurred after January 1, 1993. ⋯ We found that in 41 cases the MICU was not sent immediately. The most important reasons were minimal information available for the EMS system (n = 8), underestimation of the emergency of the call by the dispatcher (n = 10) and underestimation of the pre-alarm signs by a general practitioner (n = 7). This analysis shows that all aspects of the first link of the chain of survival need improvement.

A small number of trauma patients with penetrating thoracic trauma will require formal pulmonary resections to repair severe injuries or control massive haemorrhage. Although previous reports on this subject have addressed the management of these injuries in battle conditions, civilian experience with this type of chest injury is limited. In a 3-year period, 259 patients underwent urgent thoracotomies for penetrating thoracic trauma. ⋯ Currently, the management of patients with devastating thoracic injuries to the thoracic cavity is divided into two stages. First, initial resuscitation with rapid surgery to control major bleeding, cardiac tamponade, tracheal disruptions and potentially lethal air embolism is indicated. Once the life-threatening conditions have been resolved, definitive surgical procedures are performed to repair injuries to any of the thoracic structures.
