Reflux of gastric contents up the distal esophagus into the lungs through the fistula surgery i 81 3 b. If there is no fistula, or if it connects the trachea to the esophagus proximal to the atresia, no gi gas will be seen on x-ray examination, and the abdomen will be scaphoid. C. Tef without ea (h-type fistula) is extremely rare and usually presents after the neonatal period. The diagnosis is suggested by a history of frequent pneumonias or respiratory distress temporally related to meals. 2. Diagnosis a.

Platelets release adenosine diphosphate (adp), which causes platelet aggregation and consolidation of the platelet plug. Thromboxane a2 is released, contributing to platelet aggregation and vasoconstriction. The vessel injury also activates the coagulation cascade, which leads to thrombin production. Thrombin converts fibrinogen to fibrin, leading to clot formation as fibrin molecules, platelets, and blood cells aggregate. Refer to figures 7–3, 10–3, and 10–4 for a depiction of these processes. After the initial event, secondary events occur at the cellular level that contribute to cell death. Regardless of the initiating event, the cellular processes that follow may be similar. Excitatory amino acids such as glutamate accumulate within the cells, causing intracellular calcium accumulation. Inflammation occurs and oxygen free radicals are formed resulting in the common pathway of cell death. There is often a core of ischemia containing unsalvageable brain cells. Surrounding this core is an area termed the ischemic penumbra. In this area, cells are still salvageable. However, this is mi, myocardial infarction. Patient encounter part 1 dysfunction caused by focal brain, spinal cord, or retinal ischemia without acute infarction.

It is characterized by severity and anatomical localization. Imaging is important in the diagnosis and characterization o bi especially in the acute setting. Laboratory tests may serve as adjuncts. 250 ch apt er 15 reatment in the acute phase is supportive and directed against anatomical abnormalities and intracranial hemorrhage as per standard protocols. During the subacute phase, supportive measures are combined with prophylaxis to prevent common complications o traumatic brain injury such as pulomonary embolism or seizures. Rehabilitation, mental health interventions, and dayto-day management o medical complications are the mainstay o long-term management. Raumatic spinal cord injury is characterized by motor, sensory, and autonomic dys unction. Acute treatment is geared toward stabilization o the spine, surgical decompression, and reduction o the in ammation using steroids. In the subacute phase, supportive and prophylactic measures bridge the patient to rehabilitation. Nontraumatic myelopathies are treated in a similar way to traumatic myelopathy. Additional measures are available to the physician when speci c therapies are available or a discernable etiology. Special situations such as combined head and spine trauma or intoxication can complicate the assessment o traumatic cns disease. T xr efer ences 1. National hospital discharge survey (nhds). 2010.

Support study group of the eunice kennedy shriver nichd neonatal research network. Target ranges of oxygen saturation in extremely preterm infants. N eng/] med 201 0;362. 1959-1969. Apnea ann r. Stark i. Background a. Definition. Apnea is defined as the cessation of airflow. Apnea is pathologic (an apneic spell) when absent airflow is prolonged (usually 20 seconds or more) or accompanied by bradycardia (heart rate <100 beats/minute) or hypoxemia that is detected clinically (cyanosis) or by oxygen saturation monitoring. Bradycardia and desaturation are usually present after 20 seconds of apnea, although they typically occur more rapidly in the small premature infant. As the spell continues, pallor and hypotonia are seen, and infants may be unresponsive to tactile stimulation. The levd or duration of bradycardia or desaturation that may increase the risk of neurodevdopmental impairment is not known. B. Oassi6cation of apnea is based on whether absent airflow is accompanied by continued inspiratory efforts and upper airway obstruction. Most spells are central or mixed apnea. 1. Central apnea occurs when inspiratory efforts are absent. 2.
