[Study on the level of negative pressure of closed suction drainage of the peritoneal cavity].
An animal experiment and clinical investigations have been done to choose a suitable negative pressure of closed suction drainage of the peritoneal cavity. The results indicated that the efficiency of routine portable bulb suction devices giving 5.6-16 kPa was lower than vacuum bottles made by our hospital giving 58.86-73.15 kPa. This suggested that the level of negative pressure of the portable bulb suction devices can be increased to 58.86 to 73.15 kPa. The best one is 58.86 kPa.
