Introduction

Breaking bad news may be affected not only by insufficient knowledge of a physician, but also by his attitude, religious beliefs, fears, lack of experience, etc. This survey was aimed to test the relation between physicians’ fear of own death and philosophy of life and their inclination to break bad news.

Material and methods

One hundred seventy students of the last year of medical faculty filled in a 4-item questionnaire created by the authors. The participants were asked on their opinion on whether to inform patients on upcoming death, as well as fear of their own death and willingness to receive bad news. The last question was aimed to distinguish the respondents based on their determination in philosophy of life.

Results

Ninety-three percent of respondents think that patients should be informed about unfavorable prognosis but only 86% would like to be informed about their own upcoming death. There is a negative correlation between determination of philosophy of life and fear of own death (p = 0.024), but no correlation between fear of own death and the degree of religiousness (Fisher’s accurate p = 0.18). Persons determined to receive information on their own upcoming death are more prone to inform patients about their upcoming death (ρ = 0.31; p < 0.0001).

Conclusions

Personal fear of own death and low level of determination of philosophy of life may restrain medical professionals from breaking bad news to patients. Not only knowledge of the principles, but also personal attitude should be addressed in the curriculum of physician-patient communication education.  相似文献

Background

Data regarding the safety of endoscopic skull base exploration are very scarce. With this method, fragile vital structures (cranial nerves, the optic complex, brainstem, hypothalamus or cerebral ventricles) are exposed to direct illumination within a closed space. Also, high-speed drills, cauterization and ultrasonic aspiration deliver a significant load of thermal energy. The aim of this study was to record the temperature close to the structures of the skull base and in the intradural space during the procedures performed using extended endoscopic transnasal approaches.

Methods

The temperature of the skull base was continuously recorded during six transnasal endoscopic procedures. Implantable copper-constantan thermocouples were inserted: one into the esophagus and another through the nostril to reach the operative field at the skull base.

Results

At the beginning of the procedure, the temperature of the operative field was on average 36.8 °C?±?0.80 °C, i.e. only 1 °C higher than the esophageal temperature. Then it grew continuously during the whole procedure, to eventually reach a level of 42–43 °C at the final stage, whereas the esophageal temperature remained stable. Occasionally, the temperature increased up to 45 °C during cauterization and ultrasonic aspiration, and even up to 62 °C during high-speed drilling.

Conclusion

Endoscopic skull base surgery is associated with an incessant increase of the temperature of the intraoperative field. The temperature can peak suddenly to levels which can potentially harm neural structures and influence the rate of postoperative complications.  相似文献
