OBJECTIVE: The purpose of this study was to describe the effect of the lifting maneuver and the quantity of weight lifted on the generation of intraabdominal pressure.
STUDY DESIGN: Forty-one women who underwent urodynamic evaluation performed 4 lifting maneuvers, each while lifting 0, 2.5, 5, 10, and 15 kg. The lifting maneuvers were routine activities that included squatting with and without assistance, lifting from a counter, and receiving weight. Pressure was recorded with a rectal microtip catheter. Each lift was performed twice, and the average pressure change was analyzed.
RESULTS: When controlled for potential confounding variables, repeated-measures analysis of variance revealed a significant interaction between lift weight and lift maneuver (P<.001). Squatting was associated with generation of higher intraabdominal pressure than lifting from a counter or receiving weights into outstretched arms (P<.001). Lifting>or = 2.5 kgresulted in significant changes in intraabdominal pressure, regardless of lift maneuver (P<.001).
CONCLUSION: Both the lifting maneuver and the quantity of weight should be considered when counseling patients regarding postoperative lifting.
