Abstract
We found chronic pneumoperitoneum in two continuous ambulatory peritoneal dialysis patients from two different hospitals. Both patients used the Stay.Safe® system and bicaVera solution, whose extension tubing is not primed with fluid but air-filled, unlike that of the conventional solution bags. This fact, together with a handling fault common to both patients, resulted in the inflow of the air in the tubing of bicaVera bags into the peritoneal cavity during every exchange. We warn of this complication, which must be specifically pointed out during training, and we recommend providing the system with a mechanic device to prevent this handling fault.
