Understanding of intra-operative tourniquets amongst orthopaedic surgeons and theatre staff--a questionnaire study.
BACKGROUND
Pneumatic tourniquets are used frequently in orthopaedic theatres to provide a bloodless field whilst operating on the extremities. Their use has given rise to complications and preventable damage due to over-pressurisation and prolonged application. We designed a questionnaire to assess the knowledge on tourniquet use among operating department assistants (ODAs) and specialist registrars (SpRs) in orthopaedic surgery.


METHODS
A questionnaire was constructed using set guidelines from the Association of periOperative Registered Nurses (AORN) for recommended practice of tourniquet application. This was distributed to orthopaedic registrars with varying levels of experience and ODAs from five different NHS hospitals. The unpaired, two tailed t-test was used to test for statistical significance of results.


RESULTS
A total of 54 completed questionnaires were collected for analysis. The study population included 29 orthopaedic SpRs and 25 ODAs. The mean score for the orthopaedic SpRs as a group was 41.3% (SD 6.85; range, 29.0-54.8%). The mean score for the ODAs was 46.7% (SD 9.64; range, 23.3-62.9%) with a P-value of 0.024.


CONCLUSIONS
Most surgeons are taught how to use pneumatic tourniquets by their senior colleagues as no formal teaching is given. Most of the complications are infrequent and preventable. However, their consequences can be devastating to the patient with medicolegal implications. Our results show suboptimal knowledge of tourniquets and their use among SpRs and ODAs. This study highlights the need for amendments in training to improve the knowledge and awareness of medical practitioners on the application and use of tourniquets to prevent adverse events and improve patient safety.
