Every adventure sport comes with its fair share of risks and with these risks comes the reward. While everyone is aware of the general risks of venturing high up into the mountains, it always helps to know more about the kind of medical emergencies that could possibly arise during a trek and how best to avoid and tackle them. This article details out the information pertaining to such emergencies and provides tips to resolve the same.
Common Injuries, Illnesses, their Prevention and Remedies
Acute Mountain Sickness (AMS)
Above 3000m, the oxygen levels in the air gradually start to decline with the increase in altitude. Our body starts producing more red blood cells as a reaction to lower oxygen levels. AMS occurs when you ascend to a higher altitude in a short period of time without giving your body enough time to adjust to the change. AMS is common on high altitude treks, thus making acclimatisation a safe and important trekking practice. Symptoms of AMS include fatigue, light-headedness, headaches, loss of appetite, shortness of breath, rapid pulse, and nausea. You might notice some of these symptoms at higher altitudes as the body's common response to change in environment. However, when two or more of these symptoms exist together, AMS is suspected and if not treated at the right time, could lead to High Altitude Pulmonary Edema (HAPE) and sometimes High Altitude Cerebral Edema (HACE). HAPE is a result of accumulation of fluid in the lungs. This fluid impairs oxygen exchange and leads to decreased oxygen in the bloodstream, causing impaired cerebral function and even death. HACE results from fluid leakage that causes swelling of the brain tissue.
AMS can be avoided by following a few simple steps and giving your body ample time to acclimatise to the altitude.
- Maintain a slow pace and gain altitude at a gradual rate.
- Hydrate yourself frequently. Drink at least 3-4 litres of water everyday.
- Take ample rest. Ensure that you sleep well and are well rested for the next day.
- Eat nutritious and energy giving food. This will help your body cope with the changes in the atmosphere better.
- Everyone has different rates of acclimatisation. If you are noticing any of the above listed symptoms or generally do not feel good, do not hesitate to inform your trek leader at the earliest.
In case you are affected with AMS, take rest, descend to a lower altitude and do not proceed higher up. Stay warm and consume sufficient food for your body to recover. In severe cases, a person suffering from AMS should be airlifted to the nearest hospital.
Frostbite
In treks and expeditions which usually take you above 3000m, insulating your body becomes extremely important, particularly your palms, face and feet. Lack of or insufficient insulation could lead to frostbite, especially in snow. If you are experiencing a tingling feeling, hard skin, and numbness, it could indicate frostbite.
Frostbite occurs in different stages. The initial stage, also referred to as Frostnip, is mild frostbite that causes skin irritation and changes the skin colour to pinkish-red. This does not cause permanent damage and can be treated with first-aid. The second stage is referred to as Superficial Frostbite and results in the formation of fluid-filled blisters 12-36 hours after rewarming your skin. Deep Frostbite is the advanced stage where your skin starts turning black and hard as the tissue underneath slowly dies. You will notice large blisters 24-48 hours after rewarming, accompanied by numbness and joint/muscle impairment.
Following are a few tips to avoid frostbite:
- Wear extra layers of gloves and socks. This will provide additional insulation and keep your palms and feet warm even at higher altitudes.
- Do not walk around barefoot at campsites or dip your hands and feet in icy lakes and rivers at high altitudes. This will make you more prone to frostbite.
- Wear climbing boots and clothing that are of the right size and fit. Tight boots and clothing will restrict your blood flow. Similarly, oversized boots and clothing will not keep you warm enough.
In case you are affected with frostbite, rewarm the affected part with skin-to-skin contact. Wear more layers and keep yourself warm. For a deeper frostbite, submerge the affected part in water that is a little above body temperature. Wait until the numbness fades and bandage the area with a gauge. Do not warm the numb affected area with the help of a heat source like fire; you could end up burning yourself when you cannot feel your skin.
