Outcome of Mechanical Ventilation in Surgical Intensive Care Unit at Imam Khomeini Hospital in Tabriz

摘要: Background and Objectives Respiratory failure has a very important role in increasing morbidity and mortality of surgical patients. The objective of this study was to report the mortality and morbidity of surgical intensive care unit patients who required mechanical ventilation and compare this with other centers. Materials and Methods In this descriptive survey, we studied data on demographic and clinical profile of the patients who required mechanical ventilation in surgical intensive care unit of Tabriz Imam Khomeini Hospital in a two-year period from September 1995 till September 1997. One hundred and forty patients (71.4% male, 28.6% female) were admitted for mechanical ventilation during this period, 94.3% as an emergency and 5.7% following elective surgeries. The cause was trauma in 68 (48.6%) patients (60 cases of blunt and 8 penetrating) and other causes in 72 (51.4%). Mean age of trauma group was 35.1±16.7 year and, 57.2±19.1 for the other patients (p< 0.001). Results Indications for mechanical ventilation were as: disorders of mechanical function of the rib cage (flail chest, multiple rib fractures, diaphragm rupture, post-thoracotomy,...) in 14 (10%) decreased level of consciousness (head trauma, apnea after cardiopulmonary resuscitation, neurologic syndromes,...) in 22 (15.7%), and respiratory failure due to other causes in 104 patients (74.3%). Ten patients had a history of chronic obstructive pulmonary disease. Eighty six patients (61.4%) were mechanically ventilated for 1-7 days and 54 patients (38.5%) over 7 days. Tracheostomy was performed only in 8 cases (5.7%). The in-hospital mortality rate was 51.4% among trauma …
