Download file to see previous pages Hien Ng's personal history was also significant. He was a chronic smoker and had smoked 20 cigarettes per day for many years. On admission, a general examination of the patient revealed that he was anxious and agitated, but orientated to time and place. His skin was pale and cool to touch. Heart rate was 116 beats per minute and irregular, blood pressure was 140/95mmHg, the temperature was 37.8 C (cool peripheries), respiratory rate was 28 per minute, abdominal pain score was 6/10 and approximate weight was 68kg and height 163cm.

From the above history, it is evident that Mr. Ng was admitted to the hospital with acute gastroenteritis with dehydration and exacerbation of chronic gastric ulcers. He was subjected to both acute stress and chronic stress. At the time of admission, he was in the second stage of stress (resistance) when there were signs suggestive of the upsurge of catecholamines and cortisol.

Post admission, Mr. Ng is on 6L/min of oxygen via Hudson mask and 125 ml/hr of Hartmann’s solution. Hemodynamically, he continues to be the same. His urine output is 25ml/hr (has a urinary catheter). Blood samples have been sent for UEC (Urea, Electrolytes, Creatinine), FBC (Full Blood Count) and coagulation studies (PT, APTT).
There are approximately 40 liters of water in a 70 kg adult male which is almost 60% of the bodyweight (Ken 2004). The water is distributed between three spaces, the intravascular space (IVS), the interstitial (ISS) and intracellular space (ICS), each with a distinct function and set of physiological principles governing its volume. In normal persons, 65% of total body water is intracellular and the remaining is extracellular (26% is interstitial fluid, 8% is intravascular and the remaining transcellular like CSF, intraocular fluids, inter serous fluids, etc) (Ganong, 2003). These fluid compartments are separated by membranes that are freely permeable to water and electrolytes. ...Download file to see next pagesRead More

This is where the term was first used to describe the reaction that a person exhibits in a stressful situation. These cases were first established by Cannon Walter.

Stress response

.... The authors explain that a disturbance of homeostasis by harmful forces lead to stress. Additionally, stressors cause stress and can be either endogenous or exogenous. Coping with stress depends on various factors. Some of the factors that can determine ways of perceiving or coping stress are health, age, genetic factors and social support. Homeostasis reliability is a stress response. However, destruction of body tissues can occur with time in case there is an excess in response to stress. Neuroendocrine response and hormones are initiated when there is an excess to stress response. Stressors activate different patterns of response which in turn initiate different neuroendocrine pathways and neural. Stress is common to the human body...

Stress and the Neuroendocrine Response

... the stress alert (Gunderson & Rahe, H. 1994). Question 3 A hormone is a signaling molecule that is generated by the glands found in the multicellular organisms that are conveyed by the circulatory system to isolated organs with the aim of regulating the behavior and physiology of an individual. The hypothalamus stimulates hormones such as cortisol and adrenaline that assist a problem to deal with any pressure or threat that they are facing; this is referred to as fight response. Adrenaline hormone enable the heart rate to increase, the blood pressure also increase and thus provides the body with extra energy. The person is able to run away from the threat. These hormones also enable the suppressing of bodily roles such as digestion...

Stress and the Neuroendocrine Response

...Stress and the Neuroendocrine Response Neurotransmitters are endogenous chemical compounds that allow transmission of signals from one neuron across synapses. They communicate information throughout the brain and the body. They are also found at endings of the axon where they stimulate muscle fibers. They are produced by some glands in the body such as the adrenal gland. Dopamine is the neurotransmitter mentioned in the article that works as an inhibitory neurotransmitter. Too much stress causes changes in the hippocampal cell function. The cells in the hippocampal region die with chronic stress. Prolonged stress tends to impair the learning and memory ability of individuals, which is as a result of reduction or loss of the hippocampal...
