Background:
Patients with antiplatelet and antithrombotic therapy (AP/AT) represent a substantial proportion of ear, nose and throat (ENT) patients. Despite the ubiquitous consideration of bleeding and ischemic/thrombembolic risk, no detailed assessment of the perioperative setting in an ENT cohort is available in the literature.
Objectives:
The goal of the present work is to give a detailed assessment of patients with AP/AT in an ENT cohort resulting in ENT-specific recommendations for daily routine.
Materials And Methods:
In all, 400 randomized patients were asked regarding analgetic therapy in acute pain. Medical data of 5211 patients who underwent head and neck surgery were analyzed for AP/AT therapy. Therapeutic strategies, the perioperative AP/AT therapy, duration of intensive care treatment and hospitalization (ICT/H), application of erythrocytes and internistic/neurolocigal complication data were analyzed in patients with/without AP/AT.
Results:
Nearly 75 % of our patients were taking AP/AT due to coronary heart disease (CHD), peripheral arterial disease (PAD), cardiac arrhythmia, or cardiovascular disease (CVD). Patients' questionnaire revealed that 31 % of our patients use acetylsalicylic acid in acute pain, which represents 10 % of the overall AP/AT cohort. Head and neck surgery in patients with AP/AT showed an elevated bleeding frequency (p = 0.006) without an elevated risk for internistic/neurological complications. ICT/H were remarkably prolonged (p = 0.006; p = 0.0004).
Discussion:
Head and neck surgery in patients with AP/AT can be routinely performed. Indication for intensive care, endotracheal intubation, and tracheostomy should be made generously due to high requirements of airway management in ENT. Ischemic/thrombembolic and bleeding risk requires careful assessment in an interdisciplinary setting.
