Background& Objective: Endo-tracheal tube –associated pneumonia (ETTP) or ventilator associated pneumonia is the most dangerous complication in the intensive care units especially the surgical one (1).

The objective of this study is to evaluate the incidence of (ETTP) in the emergent surgical intensive care and its relationship to the duration of mechanical ventilation and try to define if is it linear or not .

It is important to begin our special studies in surgical intensive care units because we expect different incidence and mortality compared with international rates.

Materials & Methods: we have prospectively studied 65 patients under mechanical ventilation with endotracheal intubations during two years in the emergent surgical intensive care in Almowasat hospital from the first day of ventilation until the end which means death or weaning.

we used the clinical pulmonary infection score CPIS (2) to determine the positive cases which depends on temperature, white blood cells, neutrophils, tracheal secretions characteristics ,chest x-rays, arterial blood gases , oxygenation, and direct test and culture of secretions in positive cases.

We considered the end of ventilation according to two conditions: the first was weaning with or without (ETTP),and the second was death caused by pneumonia or other causes.

Results : patients with (ETTP) were 15 from 65 patients studied with percentage 23% and this does not exceed the international rate but the mortality was a little bit high (3)(4) ten cases among positive patients, 67%, and the relationship with duration was not linear .

Conclusion: Many factors explain this mortality ,emergent surgery , patients age and diagnosis difficulties which cause late therapy , so we need many studies in the future to determine the relationship of (ETTP) with multiple factors like ventilator , and its accessories on one hand and our medical practice on the other hand
