Association of blood level of methemoglobin with clinical outcome of patients with aluminium phosphide poisoning

خلاصه انگلیسی

Background: Although methemoglobinemia following aluminum phosphide (AlP) intoxication has been reported, probable effect of blood level of methemoglobin (Met-Hb) on outcome of AlP intoxicated patients has not yet been investigated. This study aimed to evaluate this probable association. Methods: This prospective study was carried out at Loghman-Hakim poison hospital from April 2009 to August 2009 All patients aged >12 years who had ingested AlP and were admitted at the hospital were enrolled into the study. Using the co-oximetry, Met-Hb was measured at the time of admission and was repeated 24 hours later if the patient survived. Results: 48 AlP intoxicated cases including 24 males were enrolled into the study. Mean age of the patients was 25.5± 9.5 years. There was significant association between Met-Hb blood level which measured at the time of admission and mortality (2.4%± 7.1% in survivors versus 15.2%± 13.5% in non-survivors, P<0.001). The same association was found at the 2nd day of admission (2.9%±8.2% in survivors versus 26.5%±19.9% in non-survivors, P=0.02). Conclusions: The present study found an association between blood level of Met-Hb and mortality in AlP intoxicated cases. Whether prophylactic administration of vitamin C and methylene blue can improve outcome of AlP-intoxicated cases should be investigated in future investigations.
