Defibrillation as soon as possible is the mainstay of modern emergency system in the treatment of sudden cardiac death. The emergency medical system (EMS) should be integrated with first responders in the community trained to use the semiautomatic external defibrillators (AED). Piacenza Progetto Vita is a European project of early defibrillation through lay first responders integrated within the EMS. ⋯ Survival from sudden cardiac arrest significantly increased (from 3.3% to 10.5%, p<0.01). In particular in the group of patients treated by first responders survival from ventricular fibrillation was 44.1% vs 21.2% of EMS treated group (p < 0.05). A simple training for the use of AED without cardiopulmonary resuscitation training increased survival and created a group of competent AED operator integrated within the EMS.

Review Comparative StudyPost-operative epidural versus intravenous patient-controlled analgesia.
Patient-controlled analgesia techniques have opened a new dimension to individualize patient's need for analgesia, in the treatment of acute post-operative pain. These techniques can be used intravenously, in the epidural space, and into peripheral nerve sheets. There is a common consensus that intravenous patient-controlled analgesia should not have a continuous infusion while epidural patient-controlled analgesia (PCEA) should be programmed with a continuous infusion. ⋯ The continuous epidural infusion of opioids has the advantages of fewer fluctuations in cerebrospinal fluid concentrations of drug, but it is necessary to administer a loading bolus, to overcome the fact that it takes several hours to provide adequate analgesia. The advantages of epidural versus intravenous patient-controlled analgesia are represented by better analgesia and a reduced opioids requirement, while the advantages when compared to epidural continuous infusion are: increased efficiency, self-adjustment by the patient, higher patient satisfaction, less sedation, and lower opioids dosage. The clinical advantages of PCEA may outweigh the greater cost and invasiveness of this technique.

ReviewUpper respiratory tract infections and pediatric anesthesia.
Anesthesia for the child with an upper respiratory infection (URI) presents a challenge for the pediatric anesthesiologist. Differences in study design have made interpretation and comparison very difficult. ⋯ More recent research, however, suggests that children with uncomplicated infections can undergo elective procedures without significant increase in adverse anesthetic outcomes. This presentation summarizes the evolving literature about cancellation of surgery for the child with an upper respiratory infection, perioperative outcomes and anesthetic management.

Review[Emergencies in cardiac surgery: prophylaxis or correction?].
Management of coagulation during cardiac surgery is always challenging for the anesthesiologist, even in elective operations. The strict linkage between coagulation and inflammation is amplified during cardiopulmonary bypass due to the contact of the blood with the foreign surfaces. In emergencies, coagulative derangement could be worse but the cardiocirculatory instability and parenchimal failure often overcome the attention to this problem.

ReviewPostanaesthetic shivering. Epidemiology, pathophysiology and approaches to prevention and management.
Postanaesthetic shivering is one of the leading causes of discomfort for patients recovering from general anesthesia. During EMG records, the distinguishing factor from shivering in fully awake patients is the existence of clonus similar to that recorded in patients with spinal cord transection. They coexist with the classic waxing and waning signals associated with cutaneous vasoconstriction (thermoregulatory shivering). ⋯ Prevention mainly entails preventing hypothermia by actively rewarming the patient. Postoperative skin surface rewarming is a way of obtaining the threshold shivering temperature while raising the skin temperature and improving the patient's comfort. However, it is less efficient than certain drugs such as meperidine, nefopam or tramadol, which act by reducing the shivering threshold temperature.
