Continued sickness led to the vessels abandonment in 1869. 1870: Bauer published outcomes of 25 paralyzed caisson workers. From 1870 to 1910, all prominent features were established. Explanations at the time included: cold or exhaustion causing reflex spinal cord damage; electricity cause by friction on compression; or organ congestion; and vascular stasis caused by decompression. 1871: The Eads Bridge in St Louis employed 352 compressed air workers including Alphonse Jaminet as the physician in charge. There were 30 seriously injured and 12 fatalities. Jaminet himself developed decompression sickness and his personal description was the first such recorded. According to Divers Alert Network, in its Inert Gas Exchange, Bubbles and Decompression Theory course, this is where "bends" was first used to refer to DCS. 1872: The similarity between decompression sickness and iatrogenic air embolism as well as the relationship between inadequate decompression and decompression sickness was noted by Friedburg. He suggested that intravascular gas was released by rapid decompression and recommended: slow compression and decompression; four-hour working shifts; limit to maximum pressure of 44.1 psig (4 atm); using only healthy workers; and recompression treatment for severe cases. 1873: Andrew Smith first used the term "caisson disease" describing 110 cases of decompression sickness as the physician in charge during construction of the Brooklyn Bridge. The project employed 600 compressed air workers. Recompression treatment was not used. The project chief engineer Washington Roebling had caisson disease, and endured the after-effects of the disease for the rest of his life.
Uterine perforation is a potential complication of any intrauterine procedure. It may be associated with injury to surrounding blood vessels or viscera such as the bladder or intestine. If not diagnosed at the time of the procedure it can occasionally result in massive hemorrhage or sepsis; however, the majority of uterine perforations are sub-clinical and safely resolve by themselves without treatment and do not cause any significant long-term damage. Risk factors include cervical stenosis during trans-cervical procedures or decreased strength of the myometrial wall as in pregnancy or menopause. See also
