Schöffl","doi":"10.5604/17342260.1001842","DOIUrl":"https://doi.org/10.5604/17342260.1001842","url":null,"abstract":"Objective: To evaluate the cold exposure of the personnel involved in helicopter rescue operations in an alpine environment to quantify the risk for frostbite or hypothermia. Methods: The weather conditions, the locality and its altitude and the sojourn on scene of the rescue operations of 15 months in the region Oberwallis, Switzerland were analyzed. The equivalent chill temperature was estimated with two independent models. “Mean exposure” and „worst case situation“ were calculated. The results are evaluated according to the „classic“ Siple-Passel-Model, the more recent model of Danielsson, ISO 11079, ISO 9920, the German industrial standard DIN 33403.5, and the German government regulations for work in cold environment (“G21”). Results: There were only marginal differences in chill temperature between both temperature models. Assuming “worst case conditions” the Siple-Passel-model showed 87.1% of the operations at chill temperatures >-30°C, 12.1% in the range of –30 to –45°C, and 0,8% <-45°C. The lowest temperature was –54.6°C. The Danielson model resulted in 77.6% without the risk of frostbite, 20.1% with >5% risk, 6% >50% risk, and 1.8% >95% risk. According to DIN 1.5% of the operations were performed at chill temperatures higher than cold class 1. 2.3% are class 1, 13.3% class 2, 34.7% class 3, 34.6% class 4, and 13.7% class 5. The maximal exposure times of DIN 33404.5 are exceeded in at least 0.5% of the missions. According to ISO 11079 clothing with 2.0 clo is sufficient in 40.2% rsp. 23.9% of the operations (summer, IREQ min. and IREQ neutr.). In winter the corresponding results are 0.3% and 0.0%. Duration of limited exposure is exceeded in 9.1% (IREQ min.) rsp. 19.8% (IREQ neutr.) of the operations in summer and in 10.3% rsp. 19.8% in winter. According to ISO 9920 ICL min. as well as ICL neutr. is exceeded in 100% in summer and winter operations. Conclusions: Alpine rescue operations are a typical place of work in cold – sometimes extreme cold – environment. Because of the limited time of exposure during the majority of the operations the most important danger for rescue personnel is frostbite although hypothermia cannot be excluded in cases of prolonged operations. Special advice to avoid the specific risks must be given to the crews and an examination by occupational medicine, e.g. according to „working in cold environment, G21“ of the German Berufsgenossenschaften, is recommended. Recommendations for adequate clothing are given.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"36 1","pages":"57-64"},"PeriodicalIF":0.0,"publicationDate":"2012-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90870048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: To investigate the hypothesis that test results will improve in a pre-acclimatized population after several days of further acclimatization. Methods: The Altitude Performance Test consists of an uphill run at high altitude. The event is timed and performed with continuous oxygen saturation (SaO2) monitoring. The individual’s time and lowest SaO2 measurement are recorded. This test was performed on the first day of arriving at Turin Hut (Mt. Blanc massif, Aosta Valley, Italy; elevation 3371 m), and after nine days at the same location. The 37 male participants of the German Army mountain guide course were all pre-acclimatized prior to arrival at Turin Hut. The sleeping altitude remained constant at 3371 m, and the daytime altitudes increased up to a maximum of 4808 m (Mt Blanc peak). The results of the first and second tests were compared using the Wilcoxon Signed Rank Test. Results: Test results improved significantly after a further nine days of acclimatization (Time: -11 sec, P ≤ 0.001; SaO2: +5%-points, P ≤ 0.001). This is remarkable because all soldiers were pre-acclimatized and, in general, showed only minor high altitude symptoms during the entire stay, even at the summit of Mt. Blanc. Conclusions: This indicates that the acclimatization process is not finished after amelioration of altitude symptoms. The demonstrated improvement in physical performance could prove very important, particularly during rescue or military missions performed at high altitude. Therefore, it is recommended that the additional time necessary for improved acclimatization be scheduled.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"277 1","pages":"52-56"},"PeriodicalIF":0.0,"publicationDate":"2012-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85215225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have been used as a biological marker to determine oxidative stress in newborns so far. In contrast to other markers this substance group is very stable and early detectable. Therefore, their use in a high altitude environment should be with good prospects. Objective: To test the hypothesis that acute exposure to hypobaric hypoxia induces measurable oxidative stress that might be related to the severity of AMS. Methods: Twelve subjects spent a night in a hypobaric chamber at a simulated altitude of 4000 m. One hour before altitude exposure and two hours after arrival at 4000 m a blood sample was taken and protein carbonylation was analyzed by special ELISA. Results were compared with severity of acute mountain sickness (AMS) after spending 11 hours at 4000 m quantified by the Lake Louise Score. Results: The fast ascent to 4000 m generates a measurable oxidative stress to the organism with a wide range in individual susceptibility. This appears at altitude expressed by a significant change of carbonyl proteins (P = 0.01) as well as for the severity of AMS. Three of the subjects having no or least AMS showed a decrease in carbonyl proteins. All other subjects had an increase in carbonyl proteins. The participant with the highest increase in carbonyl proteins was the most severely ill person. Regression analysis showed a linear regression; r 2 = 0.43.","PeriodicalId":93474,"journal":{"name":"Medicina sportiva (Krakow, Poland : English ed.)","volume":"27 1","pages":"70-72"},"PeriodicalIF":0.0,"publicationDate":"2012-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87128996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
