Lignocaine has been shown to improve neurological outcome of DCS, particularly when added to oxygen. Diazepam is used to prevent and treat oxygen convulsions and to control vestibular symptoms. It makes titration of treatment almost impossible because it masks the symptoms. Indomethacin is useful only when used in combination with prostaglandin and heparin. Nasal decongestants and analgesics are useful in many divers with aural barotrauma, and, rarely, antibiotics may be indicated.
Some chemotherapy is useful for marine animal injuries.
Box jelly fish Compression-immobilization bandages should be used where possible. In general, the diver should be retrieved as quickly as possible to a definitive treatment facility. A record of oxygen administration and fluid balance is essential. A transportable recompression chamber is ideal, but hyperbaric transportations are logistically difficult and considerable time-savings are needed to justify this activity. Unpressurized aircraft are intrinsically unsuitable and must fly at less than 1000 feet, which is often not possible.
