Pulmonary embolism is the least cause of hypoxia during mechanical ventilation in intensive care unit at King Hussein Hospital, Amman
Journal Title: Journal of Medical Science and Technology - Year 2015, Vol 4, Issue 1
Abstract
Objective of the study was to evaluate and assess the inducing causes of hypoxia in our intensive care unit patients subjected to mechanical ventilation. This prospective study included 413 adult patients, of both sexes, aged 33-62 years, classed I-III by the American society of anesthesiologists and admitted to our intensive care unit at King Hussein hospital, King Hussein medical city, Amman, Jordan during the period May 2012-June 2014 after obtaining written informed consent from all participants guardians and approval from our local royal medical services committee for ethical and research purposes. All patients admitted to the intensive care unit during the previous period were investigated for hypoxic events and correlated with the cause of admission. Hypoxia was defined as oxygen saturation less than 88% while on mechanical ventilation. Our study included only stable patients on mechanical ventilation with secondary hypoxemia but not secondary to the underlying cause of respiratory failure. For statistical analysis, Students t test was applied and probability value less than 0.05 were considered significant. There were 11.9% of total patients on mechanical ventilation who experienced acute hypoxic episode. The most common cause of acute hypoxia was atelectasis (32.7%). Pulmonary embolism was the least cause of hypoxia (2%) in patients on mechanical ventilation in our intensive care unit. Hypoxic episodes in patients on mechanical ventilator in the intensive care unit are not so uncommon and strict observation has to be implemented to avoid harmful outcome.
