In view of the fact that research and implementation has a history of more than half a century, selected key figures of this period are recalled, some of whom have disappeared in the fogs of history. In the specialized literature of the world, the Polish underwater habitats of Meduza are among top 6 countries that researched and implemented, this high technology of saturation diving. Regarded as the inspirer, pioneer and creator of the first saturation diving, he designed and developed the technique and decompression with the cooperation of a team of enthusiasts from clubs and professional divers, as well as engineering staff from the Tri-City enterprises. In the first part of the article the author characterizes the saturation dives in comparison with short dives with particular emphasis on decompression, which is the key to safe diving. The article also takes into account the technical conditions for the implementation of the first saturation dives. The author discusses the general methodology of validation and verification of the assumed decompression, referring to the Polish conditions. He describes how the medical, technical, and organizational problems of implementation of saturation diving were solved in the pioneering period against the background of world achievements. Furthermore, the author describes Polish habitat constructions of Meduza and Geonur types and their application to underwater work on the Polish shelf and coastal areas. Despite the great progress in the field of medicine and technology, as well as organization, the problems of saturation diving, despite the passage of time, remain relevant, as these are the most difficult dives from the point of view of organization, underwater physiology and safety technology.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"77 1","pages":"53 - 72"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41593307","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}

It is suggested that the ability to adapt to prolonged stress experienced by divers maintaining an upright position on the water surface is associated with the diver’s individual characteristics and the type of the buoyancy control device. The purpose of this study was to perform a preliminary evaluation of physiological variables in divers wearing two different types of buoyancy control device and floating upright at the surface to determine the level of safety offered by each of them. The physiological variables were measured while participants wearing a classical dive vest and a wing dive vest. The oxygen uptake and heart rate measured after 30 minutes of experiment were significantly greater in participants using wing dive vest than classical dive vest. The results confirm the possibility of using physiological indicators to compare the fatigue and rescue function in divers depending on the buoyancy control device type.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"76 1","pages":"35 - 44"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44921944","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}

The article is a review of the results of research on adverse events of hyperbaric oxygen therapy. The most common are: borotrauma of the middle ear, paranasal sinuses or lungs, oxygen toxicity can be pulmonary, ocular in extreme cases leading to cataracts, claustrophobia, pulmonary edema or hypoglycaemia. Research has shown that these events occur in the presence of high oxygen concentration or high pressure. Depending on the severity of complications, they are short-term not causing discontinuation of therapy or long-term excluding continuation of treatment. However adverse events connected with oxygen therapy are not common and are usually mild. This confirms that HBOT is an effective and safe method of treating decompression sickness, carbon monoxide poisoning, and the treatment of chronic wounds, delayed radiation injuries or necrotic soft tissue infections.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"76 1","pages":"45 - 66"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42883003","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}

There were statistically significantly more patients up to 45 years of age with anti-HAV IgG negative results than those over 45 years of age, and the Fi-square correlation coefficient (Φ2) was 0.263 between the analyzed variables. The data analysis shows that the number of people with specific IgG antibodies against hepatitis A increases with age. The risk of hepatitis A infection in people under 45 is high due to widespread seronegativity in this age group.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"76 1","pages":"67 - 76"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49471506","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}

Dexketoprofen(DEX) belongs to nonsteroidal anti-inflammatory drugs (NSAIDs) and has analgesic, anti-inflammatory, and antipyretic properties. DEX is an enantiomer of ketoprofen (S+) and has a stronger effect than ketoprofen. It is highly effective even after the administration of small doses. The therapy with DEX does not cause serious side effects and is additionally tolerated by the body. Aim. The review aimed to find original scientific publications on DEX in recent years and its therapeutic efficacy, safety, and tolerability. Method. A systematic review of scientific articles published no earlier than 2015 was carried out. Materials from the PubMed, Google Scholar, and Medline Complete databases were used. The literature review was carried out in November 2021. Among the publications found, 28 scientific articles were selected for analysis. Results and discussion. Over the recent years, there have been many publications about DEX. Articles describing new data on DEX in the treatment of pain were analyzed, compared with other drugs and mesotherapy, the latest reports of its combination with tramadol and thiocolchicoside were reviewed, and a new slow release form of DEX and new therapeutic applications of this drug were investigated. After analyzing all the studies, it was found that DEX produced similar or more effective analgesia compared to other drugs and reduced the need for emergency medications. In addition, it was noted that using DEX in combination therapy was far better than taking it alone, and was also found to be effective in raising the epileptic threshold. Mesotherapy achieved higher results in the treatment of pain symptoms compared to DEX. The side effects that appeared as a result of the use of DEX therapy were not life-threatening. Conclusion. The results of the review confirm that DEX is a very good analgesic, which is more potent than paracetamol and diclofenac sodium while having similar effects to dexmedetomidine and lidocaine. DEX in combination with tramadol or thiocolchicoside is more effective than when the two drugs are used alone. Scientists are working on the long-acting DEX and are looking for new applications of the drug in epilepsy and oncology.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"75 1","pages":"69 - 86"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42221686","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}

We present the case of a Polish Navy Dive Medical Officer (DMO) who more than 20 years ago suffered from decompression ilness - bends accompanied by cutis marmorata, numbness in one limb and mild vertigo. After treatment in decompression chamber all symptoms entirely resolved. Since then, despite of continuing diving, he experienced no decompression ilness symptoms. Twenty years later, then 52 years-old, the DMO was admitted as a patient to the Neurology Department at the Gdańsk Naval Hospital due to episodes of transient ischemic attacks. Contrast-enhanced transcranial Doppler ultrasound and transesophageal echocardiography were performed and he was diagnosed with severe right-to-left shunt across a patent foramen ovale (PFO). Retrospectively analyzing incident of DCI he suffered 20 years earlier, we suppose that it may have been caused by paradoxical air embolism associated with the RLS across the PFO, which was not diagnosed at the time of this incident yet. We conclude that although the risk of severe neurological, cutaneous or vestibular forms of DCI is very low, in order to increase diving safety, it seems to be reasonable to develop standards for initial PFO screening in certain groups of divers - professional divers, military divers and medical diving personnel. Contrast-enhanced transcranial Doppler ultrasound seems to be useful in RLS screening in divers. Using multi-compartment chambers equipped with an entry lock should be preferred for safe recompression treatment of divers.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"75 1","pages":"15 - 24"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44328980","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}
