6) Factors Influencing Symptom Severity

Essential Scorpion Sting First Response by Jonathan Leeming

Introduction

It may be logical to think that all the symptoms of a sting are a direct result of the scorpion’s venom, but this is not the case. A sting from a highly venomous scorpion does not always result in class 3 or 4 symptoms, and a sting from a mildly venomous scorpion does not always result in class 2 or 3 symptoms. 

In order to understand how additional factors influence symptom severity in humans, cats, dogs and other animals, consider the following:

Scorpion Related Factors

These factors are dependent upon the scorpion responsible for the sting. Except for occupational risks, these factors are not under our control. Significant scorpion related factors that influence symptom severity include the size of the scorpion and species of scorpion. Risk management can influence scorpion related factors.

Situation Related Factors

These factors are dependant on the situation. Although some of these factors are a result of a random encounter, many are within our control. Significant situation related factors that influence symptom severity are the amount of venom injected and multiple stings. Risk management can influence situation related factors.

Patient Related Factors

These factors relate to the state of the patient (human or animal). Some of these factors are under our control. Significant patient related factors that influence symptom severity include body mass, age related and pre-existing medical conditions. Risk management can influence patient related factors.

Response Related Factors

These factors relate to first response that was taken (if any). All of these factors are under our control. Significant response related factors that influence symptom severity include harmful and ineffective first aid, delayed first aid and professional medical assistance. Risk management can influence response related factors.

Considering all of these factors, we can appreciate how the symptoms experienced by the patient are not solely a result of the scorpion itself; there are also other factors that need to be taken into consideration. Significant factors influencing symptom severity are more likely to push symptoms up or down a class. These factors increase or decrease symptom severity.

Consider the following scenarios. Each patient has been stung by exactly the same scorpion and received exactly the same amount of venom.

A 35 Year old male with no pre-existing medical conditions. He went to the nearest hospital within 30 minutes after the sting.

A 2 year old infant who did not receive any medical care because of misdiagnosis.

A sedentary obese 70 year old man with high blood pressure, type 2 diabetes and who smokes 30 cigarettes a day. No medical treatment was given.

A Jack Russel was stung on the mouth after he ate the scorpion. A herbal remedy was applied to the sting site.

Each of these examples result in different outcomes because of unique factors for each scorpion sting event. It is important to note that many of these factors are under our control, while other factors are not.

Consider a car accident. Each accident is characterised by different factors. The type of car, whether the occupant was wearing a seatbelt, how fast the cars were travelling, age of the patient and pre-existing medical conditions. No two car crashes are treated exactly the same, because every crash is different.

Exactly the same principle applies to scorpion stings. It is important to understand how each scorpion sting event offers a unique set of circumstances that result in a unique outcome.

It is true that some venomous animals possess venom that is so biologically active that additional factors rarely shift the prognosis up or down a notch. Just as the prognosis of jumping off a 40m high cliff onto rocks, is unlikely to be influenced by the age or any pre-existing medical conditions of the patient. There are still factors that profoundly influence the prognosis, complicate medical treatment, prolong or speed up recovery.

Interpreting and quantifying these factors is challenging because each factor does not exist in isolation, but they interact with each other. It is important to take note of combinations of these factors, especially significant factors.
