Septic shock, systemic inflammation and pharmacological vasodilatation are often complicated by systemic hypotension, despite aggressive fluid resuscitation and an increased cardiac output. If the physician wishes to restore arterial pressure (>80-85 mmHg), with the aim of sustaining organ perfusion pressure, the administration of systemic vasopressor agents, such as noradrenaline, becomes necessary. Because noradrenaline induces vasoconstriction in many vascular beds (visibly in the skin), however, it may decrease renal and visceral blood flow, impairing visceral organ function. ⋯ There are no controlled human data to define the effects of noradrenaline on the kidney, but many patient series show a positive effect on glomerular filtration rate and urine output. There is no reason to fear the use of noradrenaline. If it is used to support a vasodilated circulation with a normal or increased cardiac output, it is likely to be the kidney's friend not its foe.

The World Trade Center attack. Eye witness: observations of a physician on the outside looking in.
Having personally witnessed the destruction at the World Trade Center on 11 September 2001, this paper presents my personal feelings and observations as an observer of both disaster and terror. Aside from the unimaginable horror as a result of the carnage, a feeling of helplessness was particularly prominent due to the inability to be able to care for casualties since most victims were fatalities. The passage of time has enabled a return to normalcy, however 'normalcy' carries a new definition due to the vastness of the tragedy and the sudden threat of bioterrorism and other weapons of mass destruction.

On 7 December 1988, a severe earthquake hit in Armenia, a former republic of the Soviet Union (USSR); on 11 September 2001, a manmade attack of similar impact hit New York City. These events share similar implications for the role of the uninjured survivor. With basic training, the uninjured survivors could save lives without tools or resuscitation equipment. This article makes the case for teaching life-supporting first aid to the public in the hope that one day, should another such incident occur, they would be able to preserve injured victims until formal rescue occurs.

The World Trade Center attack. Disaster preparedness: health care is ready, but is the bureaucracy?
When a disaster occurs, it is for governments to provide the leadership, civil defense, security, evacuation, and public welfare. The medical aspects of a disaster account for less than 10% of resource and personnel expenditure. Hospitals and health care provider teams respond to unexpected occurrences such as explosions, earthquakes, floods, fires, war, or the outbreak of an infectious epidemic. ⋯ In other locations, disaster drills become pro forma and have no similarity to real or even projected and predicted disasters. The World Trade Center disaster on 11 September 2001 provides new information, and points out new threats, new information systems, new communication opportunities, and new detection methodologies. It is time for leaders of medicine to re-examine their approaches to disaster preparedness.

The World Trade Center attack. Helping the helpers: the role of critical incident stress management.
Healthcare and prehospital workers involved in disaster response are susceptible to a variety of stress-related psychological and physical sequelae. Critical incident stress management, of which critical incident stress debriefing is a component, can mitigate the response to these stressors. Critical incident stress debriefing is a peer-driven, therapist-guided, structured, group intervention designed to accelerate the recovery of personnel. The attack on the World Trade Center, and the impact it may have on rescue, prehospital, and healthcare workers, should urge us to incorporate critical incident stress management into disaster management plans.
