A retrospective analysis of acute organophosphorus poisoning cases admitted to the tertiary care teaching hospital in South India.

OBJECTIVES: We have herein reported our experience with the pattern of presentation of cases of acute organophosphorus (OP) poisoning cases in a tertiary care hospital. MATERIALS AND METHODS: This retrospective study evaluated the hospital records of patients with acute OP poisoning. In a pre-structured proforma, data regarding age, sex, time elapsed after intake, circumstances of poisoning, duration of hospitalization, severity, complications, and outcome of the patients were recorded. The data were presented as mean ± standard deviation, entered in the open office datasheet, and analyzed with PSPP software. RESULTS: A total 101 patients were included in the study. Young adult males were more commonly involved than females (M:F 2.5:1). The mean age of the patients was 28 years (range 2-72 years, SD ± 14.3 years). Mean time to receive treatment was 5.2 ± 7.4 (range 1-48 h). About 45.5% patients received first aid before coming to the hospital. The reason was suicide in 88.1% cases and accident in 12 (11.9%, all children). Seventy-nine patients received pralidoxime (PAM) and the mean duration was 1.7 ± 1.1 (range 1-4 days). Atropine was given in all patients. Mean duration was 5.1 ± 3.1 (range 1-19 days). Mean hospital stay was 7.5 ± 4.7 days (range 1-26 days). Mortality was 9.9% in the present series. CONCLUSION: Although the present study contribute substantial information regarding the epidemiology and outcome of acute OP poisoning in a tertiary care teaching hospital at a district level, its relatively small sample size and the retrospective record-based nature are the major limitations of the present study. There is a further need for prospective studies to understand the underlying socio-economic factors responsible for acute OP poisoning in our population, and, accordingly, address the problems to reduce the incidence of acute OP poisoning cases.

A retrospective review of snake bite victims admitted in a tertiary level teaching institute.

OBJECTIVE: Snake bite remains major public health problem worldwide. We present our experience with cases of snake bites managed in our tertiary care teaching center of South India. MATERIALS AND METHODS: The details of all patients with snake bite admitted to a tertiary teaching care hospital from 2010 to 2012 were retrospectively retrieved and reviewed. The details regarding age, gender, first aid received or not, time elapsed between the bite, emergency care management and ASV (Anti Snake Venom) administration, site of snake bite, clinical features at the time of presentation, local examination findings at the site of bite, duration of hospital stay, need for elective ventilation, details of investigations and outcome were reviewed. The data were analyzed in PSPP software (Free Software Foundation, Inc.) for window for statistical analysis, while standard deviation (SD) was applied for the continuous variables, and proportions were applied for the categorical variables. RESULTS: Mean age was 38.4 ± 14.8 years (range 4-70 years). Majority [72 (82.8%)] were farmers. In 86.2% patients, the site of bite was in lower limbs. Snake could be identified in only 20 cases [Cobra-12 (60%), Krait-2 (10%), and Viper-6 (30%)]. Mean time to reach to hospital was 12.1 ± 21.4 hours (range 1-120 hours). Mean anti-venom therapy duration was 3.2 ± 2.0 days (range 1-14 days). Mean hospital stay was 4.7 ± 3.1 days (range 1-15 days). Majority (72.4%) made good recovery; mortality was in 4.6% cases, and 20 (23%) patients left against medical advice. CONCLUSIONS: This study identified major epidemiological and management variables related to snake bite. There is a need for a well-planned data collection and information dissemination system to avoid this potentially preventable disease.
