Review[Brain death: physiopathology and current diagnostic approach].
The concept of death has undergone many changes in the centuries depending on ages and social contexts. However death has always been identified by heart and respiratory irreversible arrest. In the last 30 years this concept has been suddenly and deeply modified by cardiocirculatory and respiratory support techniques. ⋯ In the large majority of cases the clinical and this strumental neurological findings are sufficient for the diagnosis of brain death. However in many other cases this diagnosis may be difficult because of problems in the ascertainment of the complete and irreversible lack of cerebral activities. In these cases many an strumental techniques (evoked potentials, Doppler and nuclear medicine studies) can help in the diagnosis.

Review[Respiratory mechanics and gas exchange in anesthesia for laparoscopic cholecystectomy].
To evaluate the influence of endoabdominal CO2 insufflation during anaesthesia for laparoscopic cholecystectomy on airway pressure, gas exchange and their relationships. ⋯ Laparoscopic technique for cholecystectomy, at least in healthy patients, produces relevant changes in airway pressures but only minor modifications of gas exchange, similar to those seen during general anaesthesia. This technique can be safely used for routine operation with standard monitoring equipment.
