- چکیده انگلیسی: Background: Bungarus caeruleus (common krait) bite during monsoon season is common in northwest India. Respiratory failure is responsible for high mortality in the victims. In this study we report our experience with manual ventilation using bag valve mask (BVM) in patients with neuroparalysis due to common krait bite.
Methods:This prospective study was conducted between June 2009 and December 2009. All consecutive patients with diagnosis of common krait bite who were manually ventilated by BVM were studied. The duration of ventilation and complications associated with ventilation were noted. Polyvalent anti snake venom was administered as per the "national snake bite protocol" and patients were followed up until final outcome.
Results: Thirty-four patients (70.6% men) were studied. All patients except two came from rural areas and they were hospitalized between June and September. Majority of patients were bitten during the night while sleeping on the floor. The mean time interval between bite and arrival to hospital was 4.4 hours. Ptosis (100%) was he most common clinical finding followed by ophtalmoplegia (80%) and limb muscle weakness (74%). Twenty-four patients (70%) developed respiratory symptoms and 20 (59%) were intubated and manually ventilated by BVM. Mean duration of assisted ventilation was 34.6 ± 12.8 hours. Hoarseness of voice and throat pain were noted in all intubated patients following extubation, which responded to conservative therapeutic measures. The mean duration of hospitalization was 6 ± 1.6 days. All patients except one survived.
Conclusion: Manual ventilation with BVM in patients with neuroparalysis due to common krait bite is a safe and effective modality in resource constraint settings.- انتشار مقاله: 16-11-1392

- چکیده:
- چکیده انگلیسی: Background:Epidemic dropsy occurs due to ingestion of mustard oil contaminated with oil from Argemone mexicana, leading to edema and tenderness of the abdomen, upper and lower limbs. In this study, clinical profiles of patients presented with epidemic dropsy in north India are described.
Methods: This was a prospective study of patients presented with epidemic dropsy to the emergency department of Nehru Hospital, during the period from March 2004 to December 2011. Inclusion criteria were patients presenting with tender bilateral pitting leg edema and dermal telangiectasia. Clinical and laboratory data of patients were entered into case record forms at the time of presentation until discharge from the hospital.
Results: Leg edema was the principal symptom in our series, and was in concurrence with current literature. Erythema has only been reported in 35-82% of published series, though it was present in all of our patients. Similarly, features such as diarrhea, hepatomegaly and anemia were more frequent in our cases compared to the literature. Furthermore, pancytopenia which was documented on peripheral blood counts in 54% of our cases has never been reported before.
Conclusion: Epidemic dropsy should be considered in patients presenting with progressive erythema, edema, and tenderness of the limbs who had a history of consumption of mustard oil and confirmation of Argemone oil contamination according to laboratory tests.

- چکیده:
- چکیده انگلیسی:
Background: Aluminum phosphide is the common cause of poisoning in adults in India, with a very high case fatality ratio. We studied five patients of aluminum phosphide poisoning with polyserositis.
Methods: We enrolled all patients with aluminum phosphide poisoning presenting to emergency medical department, at a tertiary care hospital in northwestern India from January to July 2006. These patients were managed according to a standard treatment protocol and their complications were recorded.
Results: During the study period, total of 35 patients were admitted with 57.5% mortality in the first 12 hours. Among the rest, 5 patients were found to develop polyserositis. All these patients had severe hypotension at presentation and developed respiratory distress requiring mechanical ventilation after an average stay of 3.8 days post-ingestion. They were managed conservatively and four of them were discharged from the hospital after the average stay of 10 days.
Conclusion: In this case series, features of polyserositis (pleural effusion, ascites and pericardial effusion) were found in 15% patients of severe aluminum phosphide poisoning. We postulate systemic capillary leak syndrome, secondary to mitochondrial damage in the endothelium, as a possible mechanism.
