L'utilisation du diamox est reconnu pour la prévention du mal aigu des montagnes (Lire l'article). L'ibuprofen serait également efficace.

 

Ibuprofen Prevents Altitude Illness: A Randomized Controlled Trial for Prevention of Altitude Illness With Nonsteroidal Anti-inflammatories

Lipman GS et all. doi:10.1016/j.annemergmed.2012.01.019


Study objective

Acute mountain sickness occurs in more than 25% of the tens of millions of people who travel to high altitude each year. Previous studies on chemoprophylaxis with nonsteroidal anti-inflammatory drugs are limited in their ability to determine efficacy. We compare ibuprofen versus placebo in the prevention of acute mountain sickness incidence and severity on ascent from low to high altitude.

Methods

Healthy adult volunteers living at low altitude were randomized to ibuprofen 600 mg or placebo 3 times daily, starting 6 hours before ascent from 1,240 m (4,100 ft) to 3,810 m (12,570 ft) during July and August 2010 in the White Mountains of California. The main outcome measures were acute mountain sickness incidence and severity, measured by the Lake Louise Questionnaire acute mountain sickness score with a diagnosis of ≥ 3 with headache and 1 other symptom.

Results

Eighty-six participants completed the study; 44 (51%) received ibuprofen and 42 (49%) placebo. There were no differences in demographic characteristics between the 2 groups. Fewer participants in the ibuprofen group (43%) developed acute mountain sickness compared with those receiving placebo (69%) (odds ratio 0.3, 95% confidence interval 0.1 to 0.8; number needed to treat 3.9, 95% confidence interval 2 to 33). The acute mountain sickness severity was higher in the placebo group (4.4 [SD 2.6]) than individuals receiving ibuprofen (3.2 [SD 2.4]) (mean difference 0.9%; 95% confidence interval 0.3% to 3.0%)

.Conclusion

Compared with placebo, ibuprofen was effective in reducing the incidence of acute mountain sickness.

Port de charges

Le port de charges lourdes est un élément important à prendre en compte. Vous ne devez pas vous charger de manière inconsidérée. Un équilibre est à trouver entre ce qui est nécessaire pour le combat, l'hydratation, l'alimentation, le matériel santé et VOS CAPACITES PHYSIQUES. Le lien suivant aborde la problématique vue par les américains.

Le traitement de l'eau

Household Water Purification: Low-Cost Interventions

Col VK Agrawal (Retd)*, Brig R Bhalwar+

Abstract

Numerous studies have shown that improving the microbiological quality of household water by point-of-use treatment reduces diarrhoea and other waterborne diseases. The most promising and accessible of the technologies for household water treatment are filtration with ceramic filters, chlorination with storage in an improvised vessel, solar disinfection in clear bottles by  the combined action of UV radiation and heat, thermal disinfection (pasteurization) in opaque vessels with sunlight from solar cookers or reflectors and combination systems employing chemical coagulation-flocculation, sedimentation, filtration and chlorination. However each of these technologies have limitations and effectiveness can be increased by use of two or more treatment systems in succession for improved treatment and the creation of multiple barriers. In particular those treatments that provide no residual disinfectant, such as boiling, solar treatment, UV disinfection with lamps and filtration could be followed by chlorination to provide a multibarrier approach. Water purifiers based on multiple interventions such as filtration/ultra filtration/ activated carbon adsorption / UV rays disinfection are available in the market which can be used to purify the water at point of use. Water purifiers based on single interventions like candle filters, resins filters or ultraviolet lamp can be used in most places being supplied water after purification. Troops on operational move can purify water by fabric/resins filtration and chlorine disinfection or by flocculent-disinfectant.

 

Altitude et acclimatation: Pas si simple

Determinants of Acclimatisation in High Altitude

Col VS Syed*, Maj Gen S Sharma+, Col RP Singh#

Abstract

Background: A total of 31 cases of effects of high altitude were admitted to a field hospital from a particular sector during the year 2008.  This study was hence undertaken to see the efficacy of acclimatisation as well as outline the determinants of acclimatisation

Methods: The study monitored the transients in the acclimatisation period as well as laid down the guidelines to certify the fitness after the acclimatisation period.

Result: Almost 4.70% of transients were found unfit to proceed to higher altitudes even after acclimatisation. Tachycardia with oxygen saturation below 90% by digital pulse oximetry were the parameters found to be statistically significant as an indicator declare a person as not fully acclimatised or otherwise.

Conclusion: The administrative authorities must ensure that an individual is fully acclimatized, based on the fitness certificat

issued, before being dispatched to their units located in high altitude areas.
