Most metastases are best demonstrated as low attenu- ation areas during the portal venous phase on a scan taken 2 60–70 seconds after the injection of contrast discount lexapro 10mg with amex anxiety remedies. Scanning 8 4a during the arterial phase purchase 5mg lexapro with mastercard anxiety cat, about 30 seconds after the injec- 7 tion of contrast order lexapro australia anxiety nausea, will show lesions such as haemangiomas 1 and some neoplasms, particularly hepatomas and highly 3 vascular metastases (e. Anatomically, the liver is divided into eight functionally independent segments (Fig. Each segment has its own 5 6 hepatic artery and portal venous infow, hepatic venous drainage and biliary drainage. This classifcation is impor- tant in hepatic surgery as each segment can be resected without damaging the remaining ones. This means each of which has its own independent vascular supply and that resection lines run parallel to the hepatic veins. It is, however, also an excellent technique for demon- images taken without intravenous contrast medium, the strating primary and secondary tumours and is often used hepatic veins and portal veins are seen as branching, low if hepatic surgery is contemplated.

In addition buy 10mg lexapro otc anxiety medication side effects, the director will need to communicate with other federal department heads to coordinate eforts on getting supplies where they will be needed the most purchase 10 mg lexapro mastercard anxiety symptoms shortness of breath. Stage 2 of the Disaster On September 21 generic lexapro 10 mg amex anxiety symptoms 4 dpo, the governor of one state activated 1,200 National Guardsmen, 1,100 state guardsmen, and state game wardens to contend with the impending crisis. In addition, the governor of that state reversed the fow of trafc, making the interstate highways one direction—only out of the major port city of that state for Case Studies: Disasters from Natural Causes—Hurricanes ◾ 57 evacuation purposes (Hays, 2005). You are receiving some good news that patients from certain major hospitals and some shut-ins have already been transferred to cities out of reach of the hurricane (Easton, 2005). However, you are now aware that trafc has been gridlocked for one state in particular and that evacuation is not occurring as fast as you would like. In addition, much of the nation’s oil refnery production centers are vulnerable (Townsend, 2005). The director should attempt to provide fueling points for vehicles that are along the evacuation route as well as food and water to the drivers. The director should contact the state emergency response coordinator and see if there are any alternative ways that trafc can be rerouted or phased into certain highways to temporarily alleviate the trafc jams. If at all possible, as much oil and chemicals as possible should be removed prior to the hurricane strikes to avoid chemical and hazardous material situations. The director should stay in close contact with other federal agency directors as well as state and local government of- cials in order to coordinate efective disaster response relief eforts. Stage 3 of the Disaster On September 24 the hurricane makes landfall between two neighboring states (Hurricane Headquarters, 2007). As the hurricane hits the coastline, three com- munities in one state are completely obliterated, with another six communities suf- fering heavy damage (Struck and Milbank, 2005). Two million people are now without electricity (Diamond, 2005), and the estimate for property damage stands at $10 billion (National Weather Service, 2007). The death toll has reached an estimated 82 people that have been killed by either direct causes of the storm or indirect causes (Knabb, Brown, and Rhome, 2006). The director should attempt to see if mobile generators are available to be deployed to communities where power has been knocked out by the storm. The director should also attempt to get fuel to those plants that have not been resupplied so that they can be back up and running fairly quickly. What is your plan to get aid to the communities that have been struck by the hurricane? The director needs to be very proactive in getting logistics moving toward cities that have no food, water, or medical supplies. The cities that have been hit the hardest will get relief aid as soon as roadways are available that can be used to transport goods to those areas. For areas that are isolated, helicopters will be needed to transport goods to those communities. What is your communication plan for interacting with other agencies and non- proft organizations? If the director does not maintain communication with the other organizations, there is a danger that relief will not be distributed properly to the afected communities, with some areas receiving too much aid while others receive nothing at all.
