Intra-abdominal Pressure Changes During Hip Arthroscopy: A Prospective Multicenter Study

To evaluate intra-abdominal pressure changes during hip arthroscopy and define its relationship with other patient related variables. A prospective multicenter study evaluating intra-abdominal pressure (IAP) in patients undergoing arthroscopic treatment of femoroacetabular impingement was performed. The IAP was measured indirectly by a bladder catheter (AbViser Autovalve Intra-abdominal pressure monitor) and documented every 30 minutes during the entire procedure. The following risk factors were analyzed: traction time, duration surgery, previous abdominal surgery, capsule repair, psoas tenotomy, and surgical approach. One hundred and five patients with symptomatic femoroacetabular impingement that underwent hip arthroscopy met the inclusion criteria. There were significant differences in the IAP between the preoperative measurement of IAP and the IAP at different time points during surgery (P
