Predictive factors for prolonged operative time in head and neck patients undergoing free flap reconstruction

摘要: Abstract Purpose Defining the predictive factors associated with prolonged operative time may reduce post-operative complications, improve patient outcomes, and decrease cost of care. The aims this study are to 1) analyze risk in head neck free flap patients 2) determine impact lengthier on surgical outcomes. Methods This retrospective cohort evaluated 282 reconstruction between 2011 2013 at a tertiary care center. Perioperative investigated by multivariate analyses included gender, age, American Society Anesthesiologists class, tumor subsite, stage, type, preoperative comorbidities, perioperative hematocrit nadir. Association was explored times complications including take back, survival, transfusion requirement, site hematoma, infection. Results Mean 418.2 ± 88.4 (185–670) minutes. Multivariate identified that ASA class III (beta coefficient + 24.5, p = .043), stage IV tumors (+34.8, p = .013), fibular flaps (−44.8, p = .033 for RFFF vs. FFF and − 67.7, p = .023 ALT vs FFF) COPD (+36.0, p = .041) were time. History CAD (−43.5, p = .010) shorter There no statistically significant association longer adverse outcomes or complications. Conclusion As expected, who medically complex, had advanced cancer, underwent complex times. Surgical planning should pay special attention certain co-morbidities such as COPD, explore innovative ways minimize Future research is needed evaluate how these can help guide algorithms patients.
