RESUMEN
A lady in her early forties was brought to our hospital in an unconscious state with history of generalized tonic-clonic seizures for last 6 h. She had multiple episodes of seizures in last 4 months, but did not receive any treatment. Relatives also gave a history of fever, headache, and vomiting for last 1 week. Her seizures were controlled with intravenous lorazepam and valproate. Clinical examination revealed a delirious patient with bilateral papilledema, brisk deep tendon reflexes, and extensor plantars. She had aspirated and had bilateral coarse crepitations on chest auscultation. Computed tomography (CT) of brain showed multiple small hyperdense calcific lesions extending throughout both the cerebral hemispheres leading to a "starry sky" appearance, suggestive of cysticercal encephalitis. The patient succumbed to progressive aspiration pneumonitis on the 6(th) day after hospitalization.
RESUMEN
BACKGROUND AND AIMS: This study was undertaken, to assess the clinical parameters in patients of poisonous snakebite, complications which occurred in them, their outcome and to evaluate various clinical predictors of mortality. MATERIALS AND METHODS: Four hundred and thirty-two patients of snake bite were admitted, of which 172 did not show any signs of envenomation and excluded. Two hundred and sixty patients had signs of local or systemic envenomation and included. Complete clinical examination, blood counts, kidney function tests, serum electrolytes, coagulation profile was done in all patients. All received tetanus toxoid and anti-snake venom (ASV). Appropriate supportive treatment was given. Clinical and laboratory parameters were compared between patients who were discharged (Group A) and those who expired (Group B). All data analysis was performed by using stata software version 10 [StataCorp LP, Texas, USA] and SPSS version 11 [SPSS Inc, Chicago, USA]. RESULTS: Out of 260 patients, 58 died and 202 survived. Mean age was 34.97 ± 14.07 years. One hundred and eighty-six (71.5%) patients were from rural areas and 74 (28.5%) from urban. 63.4% of bites occurred during rainy season. One hundred and ninety-seven (75.8%) had bite on lower limb and 62 (23.8%) on upper limbs. All 260 patients (100%) had pain at site of bite, local swelling in 252 (96.9%) and blackening of skin, blebs in 18 (6.9%). Seventy-seven (29.6%) had bleeding tendencies. Ptosis was present in all the 65 patients with signs of neuroparalysis. Eighty (30.8%) patients had acute renal failure. The mean duration of stay in survivors was 7.50 + 4.13 days and in non-survivors it was 3.45 + 3.02 days. Out of 58 who died 18 (31%) patients, succumbed within 24 hrs. On multivariate analysis, significant predictors o mortality were bleeding tendency (P = 0.013), mean PTTK (sec) (P = 0.047), respiratory failure (P = 0.045), shock (P = 0.013), mean ASV dose (cc) (P < 0.001). CONCLUSIONS: Mortality in patients with snake bite can be predicted by simple variables like presence of bleeding tendencies, respiratory failure, and shock. These parameters can help the doctors at peripheral health centers to predict outcome, so that such high risk cases can be referred to higher centers for expertise management without wasting time.
RESUMEN
BACKGROUND: Snake bite envenomation is a major public health concern in developing countries. Acute kidney injury (AKI) is as important cause of mortality in patients with vasculotoxic snake bite. AIMS: This study was to evaluate the clinical profile of snake bite patients and to determine the predictors of developing AKI following snake bite. MATERIALS AND METHODS: Two hundred and eighty-one patients with snake envenomation were included. Eighty-seven patients developed AKI (Group A) and 194 (Group B) did not. History, examination findings and investigations results were recorded and compared between the two groups. RESULTS: In group A, 61 (70.11%) patients were male and in group B, 117 (60.30%) patients were male. Out of 281 patients, 232 had cellulitis, 113 had bleeding tendencies, 87 had oliguria, 76 had neuroparalysis, and 23 had hypotension at presentation. After multivariate analysis, bite to hospital time (P = 0.016), hypotension (P = 0.000), albuminuria (P = 0.000), bleeding time (P = 0.000), prothrombin time (P = 0.000), hemoglobin (P = 0.000) and total bilirubin (P = 0.010) were significant independent predictors of AKI. CONCLUSIONS: AKI developed in 30.96% of patients with snake bite, leading to mortality in 39.08% patients. Factors associated with AKI are bite to hospital time, hypotension, albuminuria, prolonged bleeding time, prolonged prothrombin time, low hemoglobin and a high total bilirubin.
