High Altitude Cerebral Edema (HACE) and High Altitude Pulmonary Edema (HAPE) are two dreaded altitude emergencies which can independently lead to complications. Two cases of suspected comorbid HACE and HAPE were managed at 5800 m/19000 ft in Karakoram Himalayas. Altitude acclimatization, purported to prevent high altitude illness, may not be protective. Comorbid HACE and HAPE at extreme altitude may present atypically necessitating high index of suspicion and prompt clinical decision making in challenging situations. One man HAPE bag/PHC is an excellent temporary measure in cases of delayed descent/evacuation. Due attention to extreme altitude emergencies is required in view of increased recreational, scientific and military activities at extreme altitude.

Cardinal Symptom

The interest in trekking and mountaineering is increasing, and growing numbers of individuals are travelling to high altitude. Following ascent to high altitude, individuals are at risk of developing one of the three forms of acute high-altitude illness: acute mountain sickness (AMS), high-altitude cerebral edema (HACE), and high-altitude pulmonary edema (HAPE). The cardinal symptom of AMS is headache that occurs with an increase in altitude. Additional symptoms are anorexia, nausea, vomiting, dizziness, and fatigue. HACE is characterized by truncal ataxia and decreased consciousness that generally but not always are preceded by worsening AMS. The typical features of HAPE are a loss of stamina, dyspnea, and dry cough on exertion, followed by dyspnea at rest, rales, cyanosis, cough, and pink, frothy sputum. These diseases can develop at any time from several hours to 5 days following ascent to altitudes above 2,500-3,000 m. Whereas AMS is usually self-limited, HACE and HAPE represent life-threatening emergencies that require timely intervention. For each disease, we review the clinical features, epidemiology and the current understanding of their pathophysiology. We then review the primary pharmacological and non-pharmacological approaches to the management of each form of acute altitude illness and provide practical recommendations for both prevention and treatment. The essential principles for advising travellers prior to high-altitude exposure are summarized.

AbstrakHigh-altitude illness (HAI) merupakan sekumpulan gejala paru dan otak yang terjadi pada orang yang baru pertama kali mendaki ke ketinggian. HAI terdiri dari acute mountain sickness (AMS), high-altitude cerebral edema (HACE) dan high-altitude pulmonary edema (HAPE). Tujuan tinjauan pustaka ini adalah agar dokter dan wisatawan memahami risiko, tanda, gejala, dan pengobatan high-altitude illness. Perhatian banyak diberikan terhadap penyakit ini seiring dengan meningkatnya popularitas olahraga ekstrim (mendaki gunung tinggi, ski dan snowboarding) dan adanya kemudahan serta ketersediaan perjalanan sehingga jutaan orang dapat terpapar bahaya HAI. Di Pherice, Nepal (ketinggian 4343 m), 43% pendaki mengalami gejala AMS. Pada studi yang dilakukan pada tempat wisata di resort ski Colorado, Honigman menggambarkan kejadian AMS 22% pada ketinggian 1850 m sampai 2750 m, sementara Dean menunjukkan 42% memiliki gejala pada ketinggian 3000 m. Aklimatisasi merupakan salah satu tindakan pencegahan yang dapat dilakukan sebelum pendakian, selain beberapa pengobatan seperti asetazolamid, dexamethasone, phosopodiestrase inhibitor, dan ginko biloba.Kata kunci: high-altitude illness, acute mountain sickness, edema cerebral, pulmonary edema AbstractHigh-altitude illness (HAI) is symptoms of lung and brain that occurs in people who first climb to altitude. HAI includes acute mountain sickness (AMS), high-altitude cerebral edema (HACE) and high altitude pulmonary edema (HAPE). The objective of this review was to understand the risks, signs, symptoms, and treatment of high-altitude illness. The attention was given to this disease due to the rising popularity of extreme sports (high mountain climbing, skiing and snowboarding) and the ease and availability of the current travelling, almost each year, millions of people could be exposed to the danger of HAI. In Pherice, Nepal (altitude 4343 m), 43% of climbers have symptoms of AMS. Furthermore, in a study conducted at sites in Colorado ski resort, Honigman describe AMS incidence of 22% at an altitude of 1850 m to 2750 m, while Dean showed that 42% had symptoms at an altitude of 3000 m. Acclimatization is one of the prevention that can be done before the climbing, in the addition of several treatment such as acetazolamide, dexamethasone, phospodiestrase inhibitor and gingko biloba.Keywords: high-altitude illness, acute mountain sickness, edema cerebral, pulmonary edema

High altitude cerebral edema (HACE) and High altitude pulmonary edema (HAPO) are the most dreaded complications related to high altitude. Authors managed a case of HACE and HAPO simultaneously set at unusually low height (1200 ft) in a patient. The altitude was not too much to develop these comorbidities as studied earlier. Relationship with altitude was immaterial in our case. However, rapid ascent without proper acclimatisation, young and tender age, male sex and smoking were associated contributing factors. He was managed with standard protocol and descent to lower altitude.

Determining Factor

Acute high-altitude pulmonary edema (HAPE) is a pathology involving multifactorial triggers that are associated with ascents to altitudes over 2,500 meters above sea level (m). Here, we report two pediatric cases of reentry HAPE, from the city of Huaraz, Peru, located at 3,052 m. The characteristics of both cases were similar, wherein acclimatization to sea level and a subsequent return to the city of origin occurred, and we speculate that it was caused by activation of predisposing factors to HAPE. The diagnosis and management associated with pulmonary hypertension became a determining factor for therapy.

Background: Travelling to high altitude for entertainment or work is sometimes associated with acute high altitude pathologies. In the past, scientific literature from the lowlander point of view was mostly based on mountain climbing. Nowadays, altitude descent and evacuation are not mandatory in populated highland cities. Methods: We present how to diagnose and treat acute high altitude pathologies based on 50 years of high altitude physiology and medical practice in hypobaric hypoxic diseases in La Paz, Bolivia (3,600m; 11,811ft), at the High Altitude Pulmonary and Pathology Institute (HAPPI – IPPA) altitudeclinic.com.Results: Acute Mountain Sickness, High Altitude Pulmonary Edema, and High Altitude Cerebral Edema are all medical conditions faced by some travelers. These can occasionally present after flights to high altitude cities, both in lowlanders or high-altitude residents during re-entry, particularly after spending more than 20 days at sea level.Conclusions: Acute high altitude ascent diseases can be adequately diagnosed and treated without altitude descent. Traveling to high altitude should not be feared as it has many benefits;

Mountain Sickness

Healthy children and those with pre-existing conditions traveling to high altitude may experience diverse physiologic changes. Individuals who are not acclimatized and ascend rapidly are at risk of developing acute high altitude illnesses (HAI), which may occur within a few hours after arrival at high altitudes, being acute mountain sickness (AMS) the most common. In very few cases, serious complications may occur, including High Altitude Pulmonary Edema (HAPE) and very rarely High Altitude Cerebral Edema (HACE). Moreover, the number of children and adolescents traveling on commercial aircrafts is growing and this poses a need for their treating physicians to be aware of the potential risks of hypoxia while air traveling. In this article we present 50 years of medical practice at high altitude treating these pathologies succesfully with no casualties.
