Abstract
No one can deny that obesity is a major health problem worldwide, and it becomes an epidemic disease globally So that an increasing number of morbidly obese patients are being admitted to intensive care units in which the management of these patients is always challenging and sometimes nightmare
Morbid Obesity increase the risk of hypertension, coronary artery diseases, stroke, gall bladder disease, osteoarthritis, sleep apnea, respiratory problems, and cancers
Obesity is intimately related to the body mass index which is the weight in kilograms divided by the square of height in meters which is used to distinguish between obese, non obese from 18 to 65 years old, Obesity is classified according to BMI into three classes, class A (BMI from 30-34.5), class B(BMI from35-39.9) ,classC(BMI equal or more than 40)
We must be aware of the Consequences from obesity which include physiological changes of respiratory, cardiac, vascular, endocrine, immunologic systems, so that critically ill obese patients require special performance in dealing with their management
There are several challenges in the management of respiratory failure in the obese population. Pulmonary physiology is significantly altered leading to reduced lung volumes, decreased compliance, abnormal ventilation and perfusion relationships, and respiratory muscle inefficiency. These complications lead to a prolonged requirement for mechanical ventilation and increased ICU length of stay.
Any patient can have a difficult airway, but obese patients have anatomic and physiologic features that can make airway management particularly challenging.
Venous thromboembolic disease continues to be a major source of morbidity and mortality, with obese patients who are critically ill presenting some of the most at risk patients
Obesity and morbid obesity result in significant risks to both the mother and the fetus. Obesity during pregnancy increases maternal hypertension, diabetes mellitus, preeclampsia, and anesthesia complications during labor and delivery.
Timely assessment of nutritional needs is essential to improve the outcome of patients in the intensive care units (ICUs). A significant delay in feeding critically ill patients not only leads to increased risk of malnourishment but also results in delayed wound healing, increased risk of infections, and increased hospital length of stay.
So that the management of the morbidly obese critically ill patients is a challenging and a better understanding of the pathophysiological changes that occur with obesity and the complications unique to this group of patients may improve outcome.
