A 5-year experience with midline catheters in the management of major head and neck surgery patients

Abstract

Background: In the perioperative management of major head and neck surgery (HNS) patients, the performance of midline catheters (MCs) has been never tested. We present here our 5-year experience by reporting MC-related complications and by identifying the preoperative risk factors associated with their development. Methods: Clinical variables were extracted and the dwell time, the number, and the type of postprocedural complications of MCs were retrieved. Complications were classified into major (needing MCs removal and including catheter-related bloodstream infection or deep vein thrombosis or catheter occlusion) and into minor (accidental dislodgement, leaking, etc.). Descriptive statistics and logistic regression models were used in order to identify the predictors of complications. Results: A total of 265 patients were included, with a mean age of 67.4 years. Intraprocedural complications occurred in 1.1% of cases, while postprocedural complications occurred in 13.9% of cases (12.05/1000 days), but they were minor in more than 7.0% (5.4/1000 catheter-days). There were 19 minor complications (7.1% or 5.4/1000 catheter-days) while 18 (7%, 5.1/1000 catheter-days) patients experienced at least one major complication. Female sex (OR = 1.963, 95% CI 1.017–3.792), insertion in the right arm (OR = 2.473, 95% CI 1.150–5.318), and an ACE-27 score >1 (OR = 2.573, 95% CI 1.295–5.110) were independent predictors of major complications. Conclusions: MCs appear to represent an effective option in the setting of major HNS. The identification of patients most at risk for MC-related complications should prompt a postoperative watchful evaluation.
