An Annals of Surgery study found using saltier saline, and less of it, reduced complications by 25 percent in pancreatic cancer treatment cases. Jeffrey Drebin, MD, chair of Surgery, who was not involved in the research, suspects the key element is lower fluid volume rather than change in saltiness. "I think lower volume is important," Drebin said. "We and others have shown that you can use less volume without making it saltier."
