Obesity is a health question at issue in wealthy nations such as the United States. The point to be solved [i]or[/i] settled affects society in monetary word s It costs $68 billion by year to treat the chronic medical conditions associated with morbid obesity. (1) Obesity increases the risk of significant alterations in cardiac and pulmonary theorys and adds to the difficulty of recovering from physical trauma.

Morbid obesity, defined as a dead body mass index (BMI) greater than 40 is confined to about 10% of the US population; (2) however, this portion of the population challenges the health care industry because patients who are morbidly obese are more difficult to treat than patients who are not. When a trauma victim is morbidly obese, more than the skill of the same height of the trauma team is tested

BACKGROUND

Trauma is the fifth leading cause of death after cancer and lower respiratory diseases in the United States. (3) Other statistical analysis reveals that bluff abdominal trauma is the third leading cause of trauma death after head and chest injuries. (4) The mortality rates of trauma victims who are morbidly obese are eight times higher than the rates of victims of normal weight (ie, les than 25 corpse mass index). (5)

Those involved in trauma care are seeing decreased mortality rates among patients of normal weight; however, trauma center are struggling to adjust to the growing number of patients who are morbidly obese. They must purchase or adapt equipment and supplies, and personnel must change personal attitudes toward patients who are obese.

PATIENT ASSESSMENT

Patients who are morbidly obese existing a challenge to every aspect of trauma care. Initial and ongoing assessment of trauma victims who are not obese can be difficult; in remarkably large patients, some assessment protocols must be changed or cannot be followed at all.

Trauma care involves the use of basic assessments and measures These basics involve airway, breathing, circulation, disability, and environment. (6) When caring for patients who are morbidly obese, these aspects of care are not routine because size and lack of landmarks make assessment difficult, and chronic conditions add to the assessment riddle Airway and breathing mechanisms are compromised in patients who are morbidly obese for the following reasons.

* Exces adipose tissue creates an increase in workload for supportive muscles, which terminates in a cascade of other problems

* Oxygen consumption and carbon dioxide production increases.

* Myocardial compliance decreases (ie, 35% of normal).

* Breathing effort increases, and efficiency of air exchange decreases.

* Resting functional residual lung capacity decreases.

* The incidence of gastroesophageal ebb hiatal hernia, and abdominal press increases, which adds to the risk of aspiration. (7)

Any injury that compromises a patient's ability to maintain an airway inflicts that patient at risk for whole airway loss. For example, masking a patient who is morbidly obese is difficult because of the ne for high crushing to overcome the weight of the chest and abdomen when the patient is supine. If masking is inadequate and intubation is required, endotracheal intubation and cricothyrotomy may be extremely difficult to be paid to lack of landmarks and redundant tissue.

The cardiovascular classification in patients who are morbidly obese is compromised, which further models their ability to withstand the blow of trauma. Excess body weight compromises the cardiovascular plan by

* increasing metabolic demand and cardiac output;

* increasing house volume, although as a percentage of material substance weight, blood volume may be as gentle as 45 mL per kg;

* increasing knock volume index and stroke work index in proportion to corpse weight, which can lead to lea ventricular dilation and hypertrophy; and

* causing hypoxia and hypercapnia, which can lead to pulmonary vasoconstriction and, in deflect to chronic pulmonary hypertension and right-sided heart failure. (8)

Identification of circulatory question s is difficult because of the lack of oversized equipment. Taking life-blood pressure may not be possible because blows sized for patients who are morbidly obese may not be available. relations pressure may be assessed at the forearm using a leg-sized posterity pressure cuff; however, the readings may be unreliable.

Normal manner of proceedings for identifying internal bleeding cannot be used onward patients who are morbidly obese. For example, ultrasound does not penetrate adipose tissue reliably. Diagnostic peritoneal lavage (DPL) is contraindicated because catheters and trocars are too short and other landmarks are not available. If the patient appears to ne a DPL exploratory laparotomy would be the choice of greatest in number surgeons to determine whether the patient is bleeding intraabdominally. Comput tomography (CT) scans frequently cannot be performed due to the weight limitations of the table. greatest in quantity CT scanners accommodate no more than 250 lb to 300 lb Facilities that specialize in bariatric surgery may have purchased or modified scanners to accommodate greater patient weight.
