dc.description.abstractBACKGROUND: Fractional exhaled nitric oxide (FENO) is nitric oxide (NO) in the

lower airway measured by oral exhalation. FENO can be a useful non-invasive

marker for asthma. Paraquat-mediated lung injury can be reflective of an

ROS-induced lung injury. We aimed to verify if FENO is a clinical parameter of

ROS formation and responsiveness to medical therapies in acute paraquat

intoxication. MATERIAL AND METHODS: We recruited 12 patients admitted with acute

paraquat poisoning. A portable and noninvasive device called NIOX MINO (Aerocrine

AB, Solna, Sweden) was used to measure FENO. Measurements were made at the time

of hospital admission and at 24, 48, 72, 96, and 120 h after paraquat ingestion.

RESULTS: Six out of the total 12 recruited patients had general conditions (e.g.

oral pain) that made it difficult for them to exhale with adequate force. Mean

plasma paraquat level was 1.4 +/- 2.5 g/mL. We found no direct correlation

between the paraquat levels (both ingestion amount and plasma concentration) and

FENO (initial, maximal, and minimal values). All the measured FENO values were no

greater than 20 ppb for the 2 patients who died. FENO did not vary more than 20%

from the baseline. Compared to the above findings, FENO measurements were found

to be greater than 20 ppb for the patients who survived. FENO tends to reach its

peak value at between 50 h and 80 h. CONCLUSIONS: FENO did not predict mortality,

and there was no increase of FENO in patients with severe paraquat intoxication.
