    Opis:
    Introduction: Normobaric hypoxic training (NHT) for preacclimatization at home has found its way into commercial expedition mountaineering. Portable NH-generators produce a normobaric hypoxic gas mixture that can be inhaled using breathing masks at rest or during exercise or it can be pumped into lightweight tents for sleeping. These devices can be rented from commercial companies.Materials and methods: Prior to an expedition to Manaslu (8163 m) NHT was used for preacclimatization over a period of 10 days. Our regimen involved a greater increase in sleeping altitude (10 nights to reach 5400 m) than recommended by the rental company (30 nights to reach 3900 m). Results: No incidents occurred during NHT. Our regimen induced sufficient acclimatization to Manaslu Base Camp (4900 m), as evidenced by the fact that none of the expedition members suffered from AMS although they reached base camp within 2 days from Kathmandu – by helicopter flight to 3500 m and a one day walk the next day. Eight days after leaving Kathmandu, camp III was reached at 6850 m.Conclusions: At natural altitudes above 2500 m an increase of sleeping altitude should not exceed 300-500 m per day. Below 2500 m, there are no restrictions. It is therefore unclear why the company recommends such a slow increase in sleeping altitude. In our opinion, it is not necessary for healthy persons to start with a sleeping altitude below 2500 m. In contrast to natural altitudes, NH exposure can be instantly stopped if symptoms occur. Therefore, it seems safe to expose healthy persons to more liberal normobarichypoxic conditions.

    Opis:
    Background: Trekking in Nepal is popular and generally safe. However preventable trekking injuries and deaths are often the result of poor risk managementand lack of skills – i.e. acute mountain sickness (AMS) and specific First Aid (FA). Shlim and Gallie’s reviews in 1992 and 2004 of trekking deaths here found a fivefold higher risk for fatal outcomes in organized trekking tours (OT) compared to independently organised trekkers (IT), including preventable deaths (i.e. AMS). Our survey sought to identify the AMS, FA and risk management knowledge/skills of OT and IT whilst trekking in Nepal. Methods: Based on previous pilot studies at the Khumbu region in Nepal, and on risk management information provided by leading German trekking operators, a survey was conducted using two questionnaires: one each for OT and IT.The study site was Manang (3,500m) in Annapurna region, Nepal. All trekkers passing through this site who volunteered their participation were included. For evaluation descriptive statistical methods and non-parametric tests were used. Results: 442 questionnaires were completed (155 OT; 287 IT). Mean agewas 36.4 +/– 12.0y and 61% were male. Mountaineering experience was low and FA training was scarce in both groups. IT (92.7%) followed acclimatization recommendations and 59.2% carried AMS medication, compared respectively to OT at 63.2% and 25.2%. Only 27.1% of OT had repatriation plans for a medical emergency. Conclusions: Most of OT and IT were inexperienced in mountaineering and in mountain emergencies. The preparedness of OT overall was inadequate and over-reliant on the organisers whose skills may also be inadequate when responding to an emergency. Responsible trekking should require that more than one person in a group have adequate, up-to-date riskassessment/management and FA skills specific to the trek, and in particular an understanding of altitude profile, AMS, and individual abilities.

    Opis:
    Introduction: The hygienic conditions during trekking or mountaineering at high altitudes are reduced, especially regarding defecation and hand hygiene. An additional problem exists in regions above the snowline, especially in highly frequented regions: snow may be contaminated by faecal microbes, causing diarrhea. Prevention against faecal-oral infections must include not only disinfection of drinking water, but hand disinfection, too, e.g. by a water-free hand gel. The practicability of this measure was tested during a Himalaya expedition on the way to Mt. Everest. Material and methods: 10 participants were instructed to use Stokosept-Gel, an alcohol based skin disinfectant, at least prior to meals, after using a toilet and after handling boot-laces and to note each use (including additional occasions). Results: A very good practicability of using the hand gel, which was absorbed quickly (ca. ¼ min) was reported. 100 ml were sufficient for at least 2 weeks and there were no side effects or problems at the skin. During the mountaineering phase which included a total of 250 person days in the field no diarrhea occurred. Conclusion: We conclude that using such hand gels is – additional to other procedures – a very practical prevention against diarrhea in mountaineering at high altitude.
