Many times pet owners do not become aware of the seriousness of heatstroke. These minutes we left our pet in the car, terrace, sun or simply take it out for a walk, can be fatal within hours.
As veterinary assistant in a hospital in Barcelona, \u200b\u200b in this month of August, 2008, in a week we had three cases of dogs admitted for heat stroke. One case was mild, one severe and the third death in less than 24 hours.
names but I will not put races and ages, and the state in which they arrived, the days they were admitted and what they are made to stabilize and then discharge them.
The first case we had was a Saint Bernard dog , 8 years old and 50 kilos. The owners left her in the van while they were at a concert. The dog was prostrate, with tachycardia at 150 beats per minute (when normal is between 80 and 120), to 39.6 ° of body temperature (maximum 39.2 °) Acute diarrhea and wheezing. She is admitted establishing complete and carried out analytically continuous fluid and the corresponding medication.
The second case involved a French Bulldog 4 years old and 10 kilos. His owners left him in the car an hour and upon returning found him convulsing and prostrate. I soaked in water and on arrival at hospital had tremors, myoclonus (jerking of the legs), hypothermia to 35.5 ° (when the minimum is 37 º), vomiting, bloody diarrhea and prostration. 5 days was entered, making all kinds of tests blood, establishing continuous fluid and heat 24 hours because it did not increase in temperature.
The third case involved a Rottweiler of 1.6 years of age and weighing 45 kilos. was playing sports with their owners and fell into the "round" to the ground. He arrived at the hospital prostrate, panting end, tachycardia of 180 beats per minute, 41.7 ° of body temperature, vomiting and bloody diarrhea. He was admitted 1 day and died. He made all kinds of tests and controls blood pressure and could not keep it constant.
I advise you do not miss out these tips and you indicate that you do not think that you never going to happen.
HEAT STROKE II
WHAT IS IT?
One of the gravest dangers to which our animals are exposed during the summer is called heat stroke, and most people who make tourism in the car often take their pets, especially those who spend the holidays with caravans. It is at this point that we should pay particular attention to our pets, as it is very easy, with temperatures above 30 º C, may suffer a heat stroke risk your life.
Heat stroke is the common name of hyperthermia, a body heat rise so much that there is a risk of damage or malfunction of physiological processes. Its effects can be temporary or irreversible, can cause death, and for each animal depend on exposure time and temperature. The larger of these, the greater the damage.
in 10 minutes, a dog or cat can die in a car. Sometimes, even a fast rescue manages to avoid vascular problems, bleeding or cerebral edema ...
BODY TEMPERATURE IN MAMMALS
mammals have a mechanism that allows your body to regulate the temperature of deeper bodies . As a result they can survive a wide temperature changes outside. But the thermoregulatory system is not efficient enough in extreme cases, so the internal temperature continues to rise unabated in damaging the organs.
average body temperature of dogs is between 38 º and 39 º. From here, when it rises, they go off a series of internal faults, to the extent that their thermoregulatory system is also losing control of the situation, which may result in the death of the animal.
Dogs do not perspire and can only remove heat through three mechanisms: 1 .-
gasp.
2 .- The sweat only through the pads of the feet. 3 .-
isolated areas and little hair, like the belly.
termorreguladorno
This system is as effective as sweating, and therefore have less to lose heat easily. Body temperature rises to produce a failure in the thermoregulatory center in the brain and from there it is impossible to control the temperature continues to rise, moving rapidly into a coma and dying.
RISK FACTORS
1 .- Environmental factors.
1 .- High temperatures outside. 2 .- Temperature
moderate abroad after several days given the sweltering heat. 3 .-
high humidity, which makes the very removal of water vapor in the animal.
4 .- Space-saving and / or poorly ventilated, car, room, small patio, balcony, trasportín, ship hold, etc ... 5 .- Water
: small quantities, not fresh or not renewed often.
6 .- Lack of shade or shadow very low. 7 .-
cement floors.
8 .- Are you one of those who have tied up outside?: Choke add the risk of trying to get more water or shade.
indivudales 2 .- Factors.
1 .- Very young or very old and bearing the heat worse.
2 .- Heart failure Respiratory and stress weaken the animal's means of struggle against the heat.
3 .- Because of the shape of your soft palate (brachycephalic) dogs with short snout, for example, Bull Dogs, the boxer, the Pekingese and Shihtzu among other races, are more difficult to gasped. 4 .-
Obesity: the skin has more insulating power. 5 .-
Coat: thick coat reduces heat removal. However, protected from sunlight, provided there is adequate ventilation.
layer 6 .- Color: dark absorb more heat.
7 .- Ingestion: Do not feed during the day but at sunset.
8 .- Exercise, exercise, muscle produces lots of heat.
SYMPTOMS
Rapid progression of symptoms depends on the intensity of the heat input and, above all, the time the animal is exposed to this situation. The classic acute form has a rapid evolution. Death occurs within 24 hours, depression and subsequent respiratory arrest. The heat induced lesions are multifocal. 1 .-
appear when the internal temperature exceeds 42 º.
2 .- Fatigue. Lack or significant decay
forces
3 .- Muscle tremors.
4 .- Cyanosis. Bluish of skin caused by poor blood oxygenation.
5 .- Refusal to move.
6 .- Breathing very fast or very expensive.
7 .- Increased heart rate
8 .- Alteration of color of the mucous membranes, gums, ...
9 .- Altered salivation.
10 .- Staggering.
CONSEQUENCES
1 .- petechiae. Small blood spots on the skin
2 .- gastrointestinal bleeding.
3 .- Hepatic. 4 .-
renal failure.
5 .-
cerebral edema. 6 .-
multiorgan failure.
7 .- The death of patients hospitalized in serious condition can occur within 24 hours by respiratory depression and arrest.
TO DO
You can not lower the temperature of shock, because we will cause hypothermia with the same disastrous results. The temperature must be lowered gradually and the animal must rehydrate and recover the sugar and salts lost.
1 .- If you can move immediately to a veterinary clinic, car and pulled him along the way: 1 .-
Wet (or unwrapped cover) primarily the neck and head with cloths soaked in cold water or a water spray. NEVER cover it with wet towels.
2 .- Put an ice cube on the bridge of the nose, the English, and underarms. 3 .-
moisten the mouth, without forcing you to drink, and while you drink to excess.
2 .- If you can not move immediately to a veterinary clinic:
1 .- Bring to a cool place.
2 .- Soak in water about 20 º or applying a jet of water at that temperature until breathing is restored. Wet
3 .- (without wrap or cover) primarily the neck and head with cloths soaked in cold water or water spray. NEVER cover it with wet towels. If possible, we help with a fan.
4 .- Put an ice cube on the bridge of the nose, in English, and underarms. 5 .-
moisten the mouth, without forcing you to drink, and while you drink to excess.
6 .- When breathing is normal, keep it on a damp towel.
7 .- Transfer it to the vet as soon as possible, and explain everything you've done. It is imperative that a veterinarian has him under control and observation to see how it evolves, and also the animal needs medication to recover. Normal breathing eliminates no brain damage and other consequences of this strong shock, so we insist on you MUST go to the vet ASAP.
HOW TO PREVENT
1 .- In all cases:
1 .- Always have fresh clean water available.
2 .- Be in a spacious and well ventilated.
3 .- Having a large shaded area. 4 .- Give
eating early or late in the day. 5 .-
him out for a walk early and late in the day, and at noon the least to do some need.
6 .- Do you exercise.
7 .- Do not lose sight.
8 .- DO NOT LEAVE A VEHICLE PARKED IN
9 .- If you travel with him and the car has no air conditioning, take the ice, a couple of towels and water. At the stops, if you see that is hot, wet towel and leave it to lie above or at least put the legs (for pillows). You can also occasionally rub the pads with an ice cube, and the bridge of the nose.
2 .- Risk animals:
1 .- If you have a garden, let it play for a while under the sprinklers.
2 .- Delete the noon if you live in an area with no shadows or in a place asphalt or concrete.
3 .- Check with your veterinarian to give a supplement of glucose or minerals.
4 .- For puppies or the elderly who are at home, on hot days suffocating places and see replacing wet towels in which to lie, a container with water ice to be "cooling" while apart, and keep the blinds down and windows open when the sun touch here.
TEMPERATURE IN THE CAR
EXTERIOR INTERIOR
Just parked 30 º 30 º
After 10 minutes, 30 º 39 º
After 20 minutes, 30 º 43 º
After 30 minutes, 30 º 49 º
For every minute that passes
inside the car increases its temperature 0.7 º
At 43 º C outside the car, the interior can reach 56 º C in just 10 minutes and 65-70 ° C in 20 minutes, but without being directly exposed to the sun with the windows ajar. At this temperature, certain that brain death occurs shortly after showing symptoms of heat stroke. More than 50 º C occurs irreversibly brain dead. Without proper attention, it is easy for your pet fall victim to heat stroke, and is therefore extreme caution when traveling with her.
For the same reason, we recommend not transport animals in the hold of a boat in summer. is count the number of dogs and cats have died during the journey, and many who upon arrival at destination have had to be hospitalized for emergency veterinary clinics, better or worse prognosis. NO wineries are cooling, environmental unbearable heat given off by connecting the motors, plus the deafening noise. DO NOT carry or in special cages or leaving it in your car.
