ABSTRACT

Objective: Poisoning is a major prevalent problem, with thousands of deaths occurring every year, mainly in developing countries. The present study sought to identify the treatment pattern and outcomes of poisoning cases admitted to Basaveshwara Medical College and Hospital and Research Centre (BMCH and RC) and Government District Hospital and to determine the type of poison cases.

Methods: This is a prospective observational study aimed to analyse the poisoning cases admitted to general medicine departments and emergency departments of BMCH and RC and Government District Hospital, Chitradurga, Karnataka for a period of six months.

Results: A total of 100 cases were enrolled in this study. 63% of the cases were identified from BMCH and RC, with the remainder being from Government Hospital. The study shows that 41% of the cases were 21-30 y old. 48% (n=48) were males and 52% (n=52) were females. Different types of poisoning cases were observed; organophosphorus poisoning (OP) taking the lead, followed by snake bite cases. The study denotes a mortality rate of 4% and morbidity rate of 96%. A majority of cases were reported in the second quarter of the year.

Conclusion: It was concluded from the above findings that young age adults constituted a significant percentage of the subjects. It is essential, therefore, to propose policies that can terminate the free trade of poisonous pesticides and to create awareness and periodically counsel the vulnerable group of the population.

INTRODUCTION

Poison is an agent which, when administered into the body of a living being, can elicit a toxic response producing damage and resulting in death. A therapeutic substance is considered to be a poison if sufficiently larger doses are introduced into the body [1]. Poisoning has been a matter of serious concern globally since time immemorial, accounting for over a million deaths every year [2, 3], particularly in low and middle-income countries [4]. Acute poisoning is deemed a vital medical crisis, demanding immediate admission into an intensive care unit [5, 6]. Feasibility of a specific drug, its relative potency, socio-economic complexity of a population and the provision of primary care to patients are some aspects which govern the severity and management of poisoning cases [7].

In advanced countries, the main triggers for poisoning are drugs, either prescription dispensed or over-the-counter (OTC) and household chemicals [4, 7, 8], whereas in the Indian subcontinent, agriculture being the foremost occupation, the most notorious etiologic agents include pesticides and other agro based fertilizers, followed by hypnotics and sedatives, corrosive reagents, alcohol, plant poisons and household chemicals [3, 4, 7, 8]. A vast majority of cases in the developing countries arise from organophosphorus poisoning, resultant from occupational, coincidental or deliberate subjection of farmers or other workers to toxic agents [8-10].

The WHO estimates over 3 million fatalities occurring annually as a result of self-administration of pesticides. This can be minimised by restricting accessibility of these chemicals to the common man [2, 6]. Victims of intentional poisoning were mostly children, whereas suicidal poisoning was the favoured method of self-annihilation among adults [4, 5, 8, 11, 12].

Snake bite is another hazard that adds to public concern of poisons. Nearly 5 million venom bites are reported every year, with a minimum of 100 000 fatalities. India accounts for about 50 000 deaths from snake bites annually [2].

Anxiety, depression, unemployment, seclusion, failure in examinations, marital disharmonies, etc. are some of the augmenting factors for self-poisoning [4, 10, 13, 14]. In view of the increasing suicides in the country by poisoning, the Government of India enacted The Poisons Act in 1919, governing the trade of poisons and authorizing licensed personnels the sole custodians of poisonous drugs [3].

Therefore, the objectives of the present research were to study the treatment patterns and outcomes of poisoning cases admitted to BMCH and RC and Government Hospital and to determine the type of poison cases.

Type of poisoning against gender

From a sum of 100 cases, 52% female and 48% male cases were documented. Greater prevalence of OP poisoning cases (50%) was seen, the successors being snake bite cases (22%), stings (16%), honey bee bites (7%) and Nerium seed consumption (5%). A gender wise analysis shows more preponderance of females to OP poisoning. Snake bite cases were observed more in the opposite sex, followed by strings.

DISCUSSION

Globally, more than 800000 people commit suicide every year, 30% of which are due to pesticide poisoning [15]. An estimated 3 million morbidities of pesticide poisoning are reported to the WHO every year, resulting in the loss of over 220 000 lives. The past few decades have witnessed outstanding improvements in the agricultural and medicinal sectors introducing novel and more potent pesticides and drugs. Unlimited and unsafe usage of these chemicals due to insufficient knowledge and apprehension leads to poisoning [4].

The present study comprises of 100 subjects of either sex, from two different hospitals, i.e., Basaveshwara Medical College and Hospital and Research Centre (BMCH and RC) and District Government Hospital of Chitradurga, Central Karnataka, diagnosed as suffering from poisoning. The study was carried out for a duration of 6 mo. 63% and 37% cases were collected from the BMCH and RC and government hospital respectively.

Our study reports a higher preponderance of women (52%) compared to men (48%). This is consistent with the results of other studies [6, 13, 14]. Higher prevalence among females is attributable to the depressive situations women face such as domestic violence, marital conflicts or experiencing dishonour due to in-laws. Under such pressurized circumstances, women resort to committing suicide by poisoning themselves. Therefore, the availability of these chemicals is also a matter of concern [14]. On the contrary, several other studies report a higher percentage in males [4, 5, 7-9, 11, 16] owing to persistent financial burden, extra-marital relationships or occupational subjection. Hamida Jamil, in her study, notifies the higher occurrence of poisoning among unmarried men and married women [6].

In the six month duration from April to September, a large number of cases were reported to have occurred in the month of June, followed by May. The results coincide with the study conducted by Karki et al. in Nepal. The Greater prevalence of cases in the rainy season is resultant from easy accessibility of pesticides in this season or from instability in climatic conditions, posing problems to the farmers either due to heavy or insufficient downpour, thereby causing exasperation among them [17]. However, few other studies contradict this finding [4, 16]. Kanchan et al. reports more female cases in the initial 3 mo of the year and more male cases in the months from April-June [11].

Our study demonstrates that the third decade of life is most likely to succumb to poisoning. Other studies suggest similar results [4, 5, 8, 9, 11, 17-19]. This conclusion can be rationalized from the certitude that the age group of 21-30 y is the determining interval of life. Hence, these persons are more prone to traumatic affairs. Career, unemployment, relationship distress, solitude, financial crisis, fear of failure or failure itself, life settlement factors, etc. are the various triggers that urge this batch of youth to end their lives, without further considering to ponder over the issue [13]. The second most susceptible beings were those in the age group of 31-40 y as was consistent with the findings of other publishings [10, 17].

This was followed by the category of teens, i.e., 11-20 y, probable from immaturity. Children occupied the fifth position with 17.94% of the total subjects, credited to accidental exposure [12]. The age group of 51-60 y and above accounted for minimum cases, corresponding with the results of others [4, 10, 17].

The present study constitutes 5 different types of poisoning cases. These, in the order of their descent, can be categorized as follows: OP poisoning (50%), snake bites (22%), stings (16%), honey bee bites (7%), Nerium seeds (5%). The results were in concordance with other researches [4, 5, 8-10, 16-18]. This may be due to long standing exposure to these agrochemicals, or due to inadequate self-protection [4, 5, 11, 12, 16, 17]. However, the present study reveals a greater percentage of women falling victim to OP poisoning, indicative from the fact that women, in the Indian community, face several post-marital hardships which compel them to quit [9]. Snake bites (22%) and stings (16%) rank second in the list and occur more frequently in males than in females. The attributable factor in this regard is the workplace of the farm workers. Thick and dense grasslands render them readily prone to insect bites.

Patients with the various types of poisonings were immediately admitted to the emergency medicine departments. Gastric lavage was performed in 35% of the patients. 397 drugs were prescribed to the 100 patients, excluding IV fluids. The average number of drugs per prescription was found to be 3.97≈4. Antibiotics were given most frequently, followed by PPIs, anticholinergics, H2-anti-histaminics, anti-emetics, anti-amoebics, NSAIDs and anti-snake venom. Apart from these, 99 variant medications were provided. 17.38% antibiotics were authorized for use in the majority of the cases, which comprised of ceftriaxone, cefpodoxime, cefixime, levofloxacin and combinations such as piperacillin+tazobactam and ceftriaxone+salbactam. Anti-cholinergic injection atropine and the antidote pralidoxime iodide 17% were mostly used for OP poisoning. Stings were commonly treated with antihistamines and sedatives, prazosin being provided to some patients. Anti-amoebics such as metronidazole were also used. Anti-snake venom, Inj. ASV was prescribed after diluting with normal saline. Antidote charcoal was employed in 3% of the patients. Maintenance of blood pressure and electrolytes was carried out during gastric lavage, with the aid of intravenous fluids like normal saline 5%, 25%, dextrose and ringer lactate solution. The outcome of this study signifies a morbidity rate of 96% and 4% mortality rate. The extended time lapse between poison intake and hospital admission and provision of instant management are the factors affecting mortality rate.

CONCLUSION

It was revealed from the present study that females outnumbered males in both the hospital settings. Maximum numbers of cases were reported in the rainy season. Organophosphorous poisoning was observed to be the most common method. 21-30 y olds were most prone to suicidal poisoning, ascribed to their perturbation concerning future issues. Limitations of this study include small sample size, which can be justified from the reluctance of patients to participate in the research. This study illustrates the necessity of curtailing the illicit marketing of poisonous pesticides, OP compounds in particular. Disseminating knowledge regarding the safe use of pesticides and drugs is important to prevent accidental cases. Patients with psychosocial problems should be recognised at the earliest and should be provided proper counselling.
