Background and Aims: Patients often undergo paracentesis prior to a transjugular intrahepatic portosystemic shunt (TIPS) procedure to improve respiratory mechanics. However, the effect of large volume paracentesis (LVP) on intraoperative hemodynamics and anesthetic management when it is performed immediately before the TIPS procedure is not well documented. Material and Methods: This is a retrospective study in patients undergoing the TIPS procedure between 2004 and 2017. Patients were divided into two groups based on the volume of preoperative paracentesis, namely, small volume paracentesis (SVP), defined as paracentesis volume less than 5 L and LVP, defined as paracentesis volume of at least 5 L. Patients' demographics and perioperative information were collected through chart review. The Wilcoxon signed-rank test, student's t-test, and Fisher's exact test were used when appropriate. Uni- and multivariate linear regression analyses were used to determine the predictive value of paracentesis volume in relation to intraoperative hemodynamics and management of hypotension. Results: Of 49 patients, 19 (39%) received LVP and the remainder received SVP. Baseline demographics were comparable between groups as were intraoperative hypotension and volume of infused crystalloid and colloid. However, vasopressor use (P = 0.02) and packed red blood cell transfusion (P = 0.01) were significantly higher in the large volume group. Paracentesis volume was an independent predictor of the phenylephrine dose (P = 0.0004), and of crystalloid (P = 0.05) and colloid (P = 0.009) volume administered after adjusting for age, sex, body mass index, alcohol use, hemoglobin, and model for end-stage liver disease score. Conclusion: The anesthetic management of patients who undergo LVP just prior to a TIPS procedure may require larger doses of vasopressors and colloids to prevent intraoperative hemodynamic instability during the TIPS placement but may be as well tolerated as SVP.
