Although we informed staff in the emergency department staff of the importance of arterial samples for this trial, compliance was low and only 11% of arterial samples were drawn within 30 minutes of arrival.
Arterial samples were drawn for blood gas analysis from the arterial line at baseline, at the end of the procedure with the bronchoscope still placed in the trachea, and 15, 30, 45, 60, and 120 minutes after removal of the bronchoscope.
For the two excluded patients, the arterial cannula malfunctioned before arterial blood samples were drawn.
Arterial blood samples were drawn from an arterial line to determine PaCO2 and partial pressure of arterial oxygen (PaO2).
Heparinised arterial blood samples were drawn from an arterial line every 6 hours by the same nurse practitioner.
After inserting (and calibrating) the subcutaneous CGMS System Gold, heparinised arterial blood samples were drawn from an arterial line every 6 hours and analysed by both the Precision PCx point-of-care meter using test strips and the blood gas/glucose analyser ABL715.
Subsequently, part 2 was performed: after inserting (and calibrating) the subcutaneous CGMS, heparinised arterial blood samples were drawn from an arterial line every 6 hours and analysed on both the Precision PCx point-of-care meter using test strips and on the blood gas/glucose analyser ABL715.
Arterial blood samples were drawn and analyzed for pH, arterial lactate, aspartate aminotransferase, alanine aminotransferase, total bilirubin (BILT), direct bilirubin (BILD), amylase, lipase, international normalized ratio, activated partial thromboplastin time ratio, cardiac troponin I, TNF-α, IL-1β, and IL-6.
Arterial blood samples were drawn from the radial artery of each subject in 10-s intervals until 2 min, followed by samples at 3, 4, and 5 min and then every 5 min until the end of the scan at 60 min.
Arterial blood samples were drawn from the carotid artery 3 hours after injection of zymosan.
Maternal and fetal arterial blood samples were drawn at timed intervals.
