Background: This study was aimed to investigate the relation of apnea test complications with the parameters before and during the test. Methods: One hundred and seventy four patients, who were diagnosed as brain death between the years 1998-2009, were retrospectively reviewed. The effects of age, gender, cause of brain death, the time between admission and apnea test, duration of apnea test, vital signs, arterial blood gases, electrolytes and fluid balance for the last 6-12 hours before the test on the complications seen during the apnea test were evaluated. Results: The mean age of patients was 37.5±20.6 years. There were 82 female and 92 male patients. Most common causes of brain death were intracerebral hemorrhage (30.8%), subarachnoid hemorrhage (23.7%) and trauma (23.1%). The median (minimum-maximum) time between hospital admission and apnea test was 24.5 (4-1152) hours, median time for preoxygenation before the apnea test was 10 (5-30) minutes and the median duration of apnea test was 20 (3-45) minutes. Although no complications was seen during the apnea test in 72% of patients; it was observed that desaturation developed in 17%, arrhythmia developed in 2.4% and hypotension developed in 18.4% of patients. Cardiac arrest was not observed during the apnea test in any patients. The beginning partial arterial oxygen pressure (PaO2) (mean PaO2 290±126 mmHg) of the patients whose apnea test were uncomplicated (n=117) was found significantly higher than the patients with complicated apnea test (n=57, mean PaO2= 183±126 mmHg) (p<0.001). Conclusion: Beginning PaO2 value is found to be the most important parameter effecting complications during apnea test in Hacettepe University Hospitals between the years 1998-2009. This data draws attention to the importance of preoxygenation and to the need for new studies relating to preoxygenation time and beginning PaO2 values.
