Q. What should be the content of First aid box?
First aid kit should contain the following:
Q. What should one do if the patient is bleeding heavily?
Q. The person looks pale and feels cold and dizzy. What does this mean?
It means there isn’t enough blood flowing through the body. It can be life threatening because it can very quickly lead to other conditions, such as lack of oxygen in the body’s tissues, heart attack or organ damage. This physical response to an injury or illness is called shock.
If you suspect someone is going into shock, lie him down and lift his feet higher than the rest of his body. Such that the legs are higher than the heart in this position, which helps increase blood flow to their brain and heart.
Q. Should wound be washed?
For minor cuts and grazes, one can wash the wound to remove any dirt. Don't wash a wound that is bleeding heavily. If a wound that is bleeding heavily put under a tap, then all clotting agents will wash away and will bleed more.

Q. What are the causes of nose bleeding
Q. How to manage nose bleeding?
Note: Ask the patient not to sniff or blow their nose for at least 15 minutes
Q. What to do if a child is having frequent nosebleeds?
If a child is having frequent nosebleeds, one should see the doctor to know the cause of bleeding.
Snake bite is prevalent in our community for generations, and we are not able to prevent it. Education of the common man is required from snake bite, as well as measures to be taken after the bite. Snake bite may occur at any time during lifetime. WHO (2004) provided recommendations to reduce death due to snake bite as per international norms. A primary recommendation, based on evidence based procedures, was to establish a single protocol for both first-aid and treatment, and is relevant in Indian context as well.
Remember, traditional therapy have no proven benefit in the treatment of snake bite. Do not waste time and send the patient to hospital at the earliest.
First- Aid treatment protocol:
First-aid currently recommended may be remembered by mnemonic ‘’ CARRY NO R.I.G.H.T’’
CARRY: Do not let victim to walk even for short distance. Transport by conveyance, especially when bite is in legs.
NO- Pressure immobilisation, nitric oxide donor (nitrogesic ointment/nitrate spray)
R: Reassure patient, since 70% of all snake bites are from non-venomous species. Only 50% of bites by venomous type of snakes actually envenomate (poison with venom) victims.
I: Immobilise limb in a fashion similar to a fractured limb, in case of bites on the limb. A bandage or cloth is used to hold the splints. Do not apply pressure and ensure that blood supply is not blocked. Compression in the form of tight ligatures does not work and may be dangerous even.
GH: Get to Hospital immediately.
T: Tell any systemic symptoms that manifest on way to hospital.
Do not waste time in first aid management by traditional methods which may dangerously delay effective treatment.
Resuscitation and treatment of breathing problem is a priority. Life threatening injuries should also be taken care of.
Patient is monitored for any worsening of symptoms, chiefly breathing or pertaining to cardiovascular system.
Look for fang (poisonous tooth) marks in the area of bite.
Limbs are divided into compartments of muscles, blood vessels and nerves. Compartment syndrome is a rare complication. It is seen in excessively swollen limbs. Severe swelling may cut off blood circulation to a particular compartment.
I. Diagnosis phase general assessment:
Diagnosis phase general assessment depends upon the type of symptoms. Depending upon the species, clinical features may include:
Response to neostigmine and anti- snake venom (ASV) may be studied.
II. Diagnosis phase investigations:
Send blood and urine samples to the laboratory to look for any evidence of bleeding, muscle death and for assessment of kidney function.
Management should be carried out under medical supervision.
Snakes can continue to bite and inject venom with successive bites till the venom is exhausted. Prevent a second bite or attack on another victim. Therefore, do not try to catch snake as this may lead to further bites. Identify the snake if possible but not at the cost of additional bite.
Every snake bite victim should attend emergency department in a hospital.
Patients with local necrosis may be given antibiotics and tetanus toxoid booster.
Remove any constricting item such as ring which may cut off blood flow in case of swelling of bite area.
In past, suction was applied to remove toxin. It is no longer recommended, since suction may further damage local tissue.
II. Anti- snake venom:
When indicated, start ASV with whatever dose is available in hand (pending availability of full dose). In India, only polyvalent ASV is available. It is effective only against four common varieties of snakes (king cobra, Russells viper, saw scaled viper and common krait). Bites by other species, depending upon the geography, require special measures. These species need to be identified first.
Criteria for ASV administration:
ASV is a costly and scarce item. It should be administered only when there are definite signs of envenomation. Only free flowing and unbound venom, in tissue fluid or bloodstream can be neutralised.
ASV carries the risk of anaphylactic shock and therefore, should not be used unnecessarily.
Indications of ASV:
I. Systemic envenoming
II. Severe current local envenoming
Purely local swelling, even if accompanied by bite mark/s from an apparently venomous snake, is not a ground for giving ASV.
Clinical decision is very important and the dose of ASV required varies from case to case. Ten to thirty vials are usually required. All victims do not require 10 vials of ASV. However, starting with 10 vials ensures sufficient neutralising power against average amount of injected venom. It also ensures neutralisation during next 12 hours of any free flowing venom.
No ASV test dose is given, since it does not have predictive value in detecting anaphylactic or late serum sickness reactions. Rather, these may pre-sensitise the victim and may pose greater risk.
Two methods of administration are recommended
Recommended initial doses of ASV:
ASV is administered over 30- 60 minutes at constant speed. Liquid or reconstituted ASV in isotonic saline or glucose without any diluent fluid in volume overload victims is given.
Local administration of ASV near the site of bite is ineffective, painful and in fact raises intra-compartmental pressure. Particularly, it is not injected in digits.
How long anti-venom is expected to be effective after the bite:
Anti-venom should be given as soon as it is indicated. It may reverse systemic envenoming even when it has persisted for several days, and in case of haemostatic abnormalities, for two or more weeks. It is appropriate to give anti-venom as long as evidence of coagulopathy persists.
On recovery, ASV may be restarted slowly for 10- 15 minutes, keeping the patient under close observation. After that, normal flow is maintained.
III. Neurotoxic envenomation:
IV. Anti-haemostatic repeat dose:
In case of anti-haemostatic envenomation, adopted ASV strategy is to keep six hour time period in which clotting time is repeated. Repeat ASV dose is given over one hour in case of persisting coagulation defect. Same cycle is repeated until coagulation is restored or the species of snake is identified against which polyvalent ASV is ineffective. Repeat dose may be ten vials of ASV similar in quantity to the first dose.
V. Haematotoxic repeat dose:
Normal guidelines are to administer ASV every six hours until coagulation is restored. What should be done when 30 vials have been exhausted and the coagulation abnormality persist. One study has shown that even up to 50 vials (500 ml) may be given for haematotoxic poisoning. Envenomation by certain species does not respond to ASV. Coagulopathy may persist for up to three weeks in those cases.
VI. Role of surgery:
