[Challenges in the context of medical care during a naval research expedition. A case report].

Exploration for natural resources in the seabed of the Indian Ocean was undertaken by the German government institution of earth sciences and resources ("Bundesanstalt für Geowissenschaften und Rohstoffe", BGR) in November 2012. To provide for the medical safety of crew and scientists, a cooperation between the BGR and the trauma department of the Hannover Medical School was established. Research by physicians accompanying the naval expedition revealed that medical consultations mainly occur because of respiratory infections, abdominal discomfort, genitourinary discomfort and seasickness, with the rate of traumas being between 31% and 41%. Di Giovanna et al. stated that 97% of all emergencies on cruise ships are not critical and only 3% need an immediate emergency medical intervention. Consultations were already performed on the mainland prior to departure and included minor traumas due to non-appropriate footwear, otitis and respiratory infections. Seasickness was the main reason for consultation during the first days at sea. Strong seas resulted in some bruises. Minor injuries and foreign body injuries to the hands and feet also required consultation. First-degree sunburns resulted from exposure to the sun, while air-conditioning caused rhinosinusitis and conjunctivitis. A special consultation was a buccal splitting of tooth 36. An immediate emergency medical intervention was not necessary due to the relative low level of pain for the patient; however, due to the risk of further damage caused by nocturnal bruxism, a protective splint was formed using a small syringe. Other reasons for consultation were similar to those reported in the general literature. Medical activities at exotic locations may create the vision of a holiday character at first; however, intensive planning and preparation are needed. We recommend contacting police, customs, the federal institute for drugs and medical devices as well as the labour inspectorate, preferably in both the originating country and the destination, to prepare custom formalities and to obtain formal documents and approvals beforehand. It is advisable to be prepared not only for emergency situations, but also for general medical and dental problems. Improvisation in the treatment of special health problems is an unavoidable requisite.
