| Abstrakt: | Objective: Active surgical drains minimize fluid accumulation in the postoperative period. The Jackson-Pratt (JP) system consists of a silicone drain connected by flexible tubing to a bulb. When air in the bulb is evacuated, negative pressure is applied at the surgical site to aspirate fluid. The objective of this study was to determine if the evacuation method and volume of accumulated fluid affect the pressure generated by the bulb. Methods: Bulbs were connected to a digital manometer under various experimental conditions. A random number generator determined the initial evacuation method for each bulb, either side-in or bottom-up. Subsequent evacuations were alternated until data was collected in triplicate for each method. Predetermined amounts of water were placed into the bulb; air was evacuated; and pressure was recorded. The digital manometer was allowed to equilibrate for 1 minute prior to data acquisition. Results: The average amount of pressure after a side-in evacuation of a JP bulb was 87.4 cm H Conclusions: JP drains generate negative pressure in order to reduce fluid accumulation at surgical sites. Although its function is frequently taken for granted, this study demonstrates that both the specific method for evacuating the bulb as well as the amount of fluid in the bulb significantly affect the performance of this device.
