- Brief Summary
The aim of this study is to evaluate efficacy and safety of Alpha Lipoic Acid(ALA) as an adjuvant in the management of patients with acute phosphide poisoning.
- Detailed Description
The study will be carried out following approval of the research ethical committee of Tanta Faculty of Medicine on patients admitted to The Poison Control Unit (Emergency Hospital, Tanta University and Emergency Hospital, Mansoura University) with acute phosphide poisoning in the period from January 2016 to January 2018. A written informed consent will be taken from each patient or his/her guardians (if the patient was unable to participate in the consent process). Confidentiality of the data will be maintained by making code numbers for each patient. The investigators plan to conduct a randomized clinical trial to evaluate efficacy and safety of ALA as an adjuvant in treatment of patients with acute phosphide poisoning. Fifty patients will be randomized to ALA or a non ALA in a 1:1 ratio (25 patients in each group). ALA will be given IV, as a dose of 600 mg/12 hours. Patients will be monitored and a detailed documentation of any adverse effect due to ALA therapy will be recorded.
This intervention represents an added treatment to the existing standard of care. All patients will continue to receive standard treatment, which is determined by the attending physician who maintains clinical responsibility for all patients. It consists of patient resuscitation, gastric decontamination (with sodium bicarbonate, and activated charcoal \[1 g/Kg, orally\] in the first 6 hours after onset of poisoning), adequate hydration and supportive treatment. All the patients will be followed up until discharge or death. All patients will be subjected to:
I. History. II. Clinical examination. III. Laboratory investigations: At admission and repeated before discharge.

Patients (male or female, aged 12 years or older) with symptomatic acute phosphide poisoning (deliberate or accidental), with diagnosis made on the basis of:
- The typical clinical manifestations due to and following shortly after a single exposure to phosphide.
- Reliable identification of the compound based on the container brought by patient attendants or a subsequent confirmation by silver nitrate test for phosphine detection in stomach contents.
- Patients less than 12 years of age
- Pregnant and lactating women
- Patients with ingestion or exposure to other substances in addition to phosphide.
- Patients with other major medical conditions (e.g. cardiovascular disease, renal or hepatic failure).
- Patients presenting more than 6 hours of having consumed the phosphide compound (late presenters).
- Patients treated for acute phosphide poisoning in any medical center before admission.
