Abdominal compartment syndrome (ACS) is a rare but potentially fatal complication that can occur during hip arthroscopy. This usually occurs as a result of arthroscopic fluid passing into the retroperitoneal space through the psoas tunnel. From the retroperitoneal space, the fluid can then enter the intraperitoneal space through defects in the peritoneum. Previous studies have identified female sex, iliopsoas tenotomy, pump pressure, and operative time as potential risk factors for fluid extravasation. We present a method to measure intraoperative fluid deficit during hip arthroscopy to alert surgeons to possible ACS. Our proposed technique requires diligent intraoperative monitoring of fluid output through various suction devices, including suction canisters, puddle vacuums, and suction mats. The difference is then calculated from the fluid intake from the arthroscopic fluid bags. If the difference is greater than 1500 mL, then the anesthesiologist and circulating nurse are instructed to examine the abdomen for distension every 15 minutes. This, combined with other common symptoms such as hypotension and hypothermia, should alert the surgical team to the development of ACS. Despite limitations to this technique, this approach offers an objective method to calculate intra-abdominal fluid extravasation., Technique Video Video 1 Video depicts normal operating room workflow using various suction devices to collect arthroscopy irrigation fluid. This process occurs during each hip arthroscopy case in conjunction with the anesthesiologist, circulating nurse, and primary surgeon. The patient is positioned in the supine position with traction using a post. The image seen at 0:38 is a fluoroscopic anteroposterior image of the right hip. Please refer to Figure 1 for more details. The image seen at the 1:07 is a right hip viewed from the anterolateral portal. Please refer to Figure 2 for more details.
