Comparison of a perfusion simulator to a clinical operating room: evaluation of eye tracking data and subjective perception. A pilot study.

Background: With the aim of evaluating the perfusion simulator at the German Heart Center Berlin, similarity between simulation and clinical operation room (OR) was investigated regarding subjective perception and eye movement.

Methods: Eight perfusionists performed an operation on the heart-lung machine (HLM) wearing eye tracking glasses, each in real OR and simulator. The three most important phases for perfusionists (going on bypass, cardioplegia administration and coming off bypass) were considered.

Simulation-based training of critical events during cardiopulmonary bypass: importance of a critical events checklist.

Objectives: Evaluation of critical events training for clinical perfusionists is necessary to improve this educational approach. Critical events checklists are effective in reducing clinical complications, but should be tested in a simulation environment first. Individual behavior and stress response of clinical perfusionists during simulated critical events on cardiopulmonary bypass have not been evaluated yet.

Evaluation of attention, perception, and stress levels of clinical cardiovascular perfusionists during cardiac operations: a pilot study.

Background: Performing cardiopulmonary bypass is a complex task which involves evaluating visual input from patient monitors and technical parameters displayed at the heart-lung machine console as well as reacting to other sensory input. Only few studies are available concerning the competency requirements for clinical cardiovascular perfusionists, including attention, perception, and coping with mental stress. This study aims at evaluating attention, perception, and stress levels of clinical cardiovascular perfusionists during cardiopulmonary bypass.

Influence of meteorological conditions on post-tonsillectomy haemorrhage.

Aim: To evaluate the relationship between the incidence of primary post-tonsillectomy haemorrhage and the daily weather condition, over a five-year period.

Study Design And Setting: This was a retrospective study carried out in the ENT department of the Split University Hospital between January 2000 and December 2004.

Results: Out of 3377 patients undergoing tonsillectomy, primary post-operative haemorrhage occurred in 83 (2.

Primary mucosal melanoma of the eustachian tube.

Melanomas of the upper airway tract constitute around 1% of the total melanomas of the head and neck. They are usually more advanced in depth of invasion or size at the time of diagnosis than melanomas of the skin. The case of a 74-year-old Caucasian female with primary malignant melanoma of the left eustachian tube and bilateral neck metastasis is presented.
