The recommended temperature for bladder irrigation is 30-33 degrees, which is the optimal temperature for the irrigation fluid. Too hot flushing fluid tends to cause bladder vasodilatation and increase the risk of bleeding. Too low temperature flushing tends to cause bladder spasm, which leads to lower abdominal pain and secondary bladder spasm, which also tends to cause bleeding. It is recommended that when bladder flushing, the temperature of the flushing solution should be effectively controlled, and the speed of the flushing solution should be effectively controlled. The flushing solution should not be flushed too fast, and the speed of the flushing solution should be determined by the color of the urine volume. This effectively reduces bleeding, effectively reduces blockage of the tube, and effectively reduces the occurrence of bladder spasms.
