RESUMO
The use of pneumatic tourniquets during the harvest of free flaps is an established practice in oral and maxillofacial surgery. Their use can be associated with severe but preventable complications, for which operating surgeons are ultimately responsible. The aim of this study was to find any pitfalls concerning the safe use of tourniquets by maxillofacial surgeons. An electronic questionnaire based on the Association of Perioperative Registered Nurses (AORN) guidelines was distributed to maxillofacial surgeons nationally. A total of 37 questionnaires were completed and analysed. The mean (range) score for the knowledge-based questions for all respondents was 72.8% (47.3%-94.7%). The number of clinicians who answered correctly on topics relating to cuff position, reperfusion time and contraindications for the use of tourniquets were 15, 10 and 6, respectively. A total of 35 clinicians had had no formal training on the application of a tourniquet. Our study shows that knowledge about their use by maxillofacial surgeons is poor, and it highlights the importance of formal education during basic and higher surgical training.
