The effects of dissection-room experiences and related coping strategies among Hungarian medical students
Background:
Students get their first experiences of dissecting human cadavers in the practical classes of anatomy
and pathology courses, core components of medical education. These experiences form an important part of the
process of becoming a doctor, but bring with them a special set of problems.
Methods:
Quantitative, national survey (n = 733) among medical students, measured reactions to dissection
experiences and used a new measuring instrument to determine the possible factors of coping.
Results:
Fifty per cent of students stated that the dissection experience
does not affect them
. Negative effects were
significantly more frequently reported by women and students in clinical training (years 3,4,5,6). The predominant
factor in the various coping strategies for dissection practicals is
cognitive coping
(rationalisation, intellectualisation).
Physical
and
emotional
coping strategies followed, with similar mean scores. Marked gender differences also
showed up in the application of coping strategies: there was a clear dominance of emotional-based coping among
women. Among female students, there was a characteristic decrease in the physical repulsion factor in reactions to
dissection in the later stages of study.
Conclusions:
The experience of dissection had an emotional impact on about half of the students. In general,
students considered these experiences to be an important part of becoming a doctor. Our study found that
students chiefly employed cognitive coping strategies to deal with their experiences.
Dissection-room sessions are important for learning emotional as well as technical skills. Successful coping is
achieved not by repressing emotions but by accepting and understanding the negative emotions caused by the
experience and developing effective strategies to deal with them.
Medical training could make better use of the learning potential of these experiences
Qualitative Analysis Reveals Complex Patterns of Medical Student Experiences in the First Dissection
Closed-loop vasopressor control: in-silico study of robustness against pharmacodynamic variability
Initial feasibility of a novel closed-loop controller created by our group for closed-loop control of vasopressor infusions has been previously described. In clinical practice, vasopressor potency may be affected by a variety of factors including other pharmacologic agents, organ dysfunction, and vasoplegic states. The purpose of this study was therefore to evaluate the effectiveness of our controller in the face of large variations in drug potency, where 'effective' was defined as convergence on target pressure over time. We hypothesized that the controller would remain effective in the face up to a tenfold variability in drug response. To perform the robustness study, our physiologic simulator was used to create randomized simulated septic patients. 250 simulated patients were managed by the closed-loop in each of 7 norepinephrine responsiveness conditions: 0.1 ×, 0.2 ×, 0.5 ×, 1 ×, 2 ×, 5 ×, and 10 × expected population response to drug dose. Controller performance was evaluated for each level of norepinephrine response using Varvel's criteria as well as time-out-of-target. Median performance error and median absolute performance error were less than 5% in all response levels. Wobble was below 3% and divergence remained negative (i.e. the controller tended to converge towards the target over time) in all norepinephrine response levels, but at the highest response level of 10 × the value approached zero, suggesting the controller may be approaching instability. Response levels of 0.1 × and 0.2 × exhibited significantly higher time-out-of-target in the lower ranges (p < 0.001) compared to the 1 × response level as the controller was slower to correct the initial hypotension. In this simulation study, the closed-loop vasopressor controller remained effective in simulated patients exhibiting 0.1 to 10 × the expected population drug response
