However, because the arterial blood gas parameters were good, the hemodynamics of the patient were stable, and the methemoglobin
concentration was not very high, the patient was extubated after surgery; she was relaxed, cooperative, and had adequate respiration.
is unable to bind oxygen and shifts the oxygen-dissociation curve to the left .
The diagnosis of nitrate/nitrite intoxication is based on herd and feeding history, epidemiology, clinical signs, and results of complementary tests such as hemogasometry, methemoglobin
dosage, anatomopathological examination, diphenylamine test, and nitrate dosage in grass and water (RADOSTITS et al., 2007; JONCK et al., 2013).
MRI will best show typically high T1 methemoglobin
extending distal to the mid-axis body, overlying the intact, uninjured tectorial membrane at the craniocervical junction.

In light of his elevated carboxyhemoglobin and methemoglobin
levels, we asked him social and exposure questions.

The rainbow SET technology analyzes multiple wavelengths of light to accurately measure total hemoglobin, oxygen content, carboxyhemoglobin, methemoglobin
and Pleth Variability Index non-invasively and continuously.
The first generation of portable POC hemoglobin devices with single-use, dry reagent cuvettes operates based on a modification of Vanzetti's azide methemoglobin
High intake of nitrate and its subsequent reduction to nitrite leads to the formation of methemoglobin
(MetHb) which is the most detectable sign of nitrite and nitrate toxicity in humans especially in infants (1).
(MetHb) concentrations have been evaluated in cats exposed intravenously to NMA or aniline at a dose of 30 mg/kg b.w.
Reported negative patient effects from surgical smoke exposure include port site metastasis; increased levels of carboxyhemoglobin; occurrence of methemoglobin
; exposure to carbon monoxide; and postoperative nausea, vomiting, and headaches.
