[ survey on comparison of tympanic and nasopharyngeal temperatures in patient undergoing open heart surgery]

Body temperature controlling in patient undergoing open heart surgery is very important and critical. In fact it is the base of work and by measuring temperature correctly, complications of hypothermia can be prevented. The overall purpose of this study was to determine and compare tympanic and nasopharyngeal temperatures in patient undergoing open heart surgery with hypothermia. This was a correlation study. The sample consisted of 60 patients undergoing open heart surgery with hypothermia. Body temperatures are measured in three sites - right ear, left ear and nasopharynx. Both of them were measured simultaneously before, during and after hypothermia. Tympanic temperatures were measured with an infrared thermometer and the nasopharyngeal temperatures were monitored by heart and lung machine, in fact it is a process in open heart surgery. This study showed that the mean of body temperatures are different in three sites. The difference between right and left ear wasn't significant, but the mean of nasopharyngeal temperature was significantly different with right and left ear. In order to determine the sensitivity of tympanic to changes of temperature, correlations between three sites - right ear, left ear and nasopharyngeal - are calculated. Temperatures at three sites had a high correlation [p= 0.01]. All sites are sensitive to changes of body temperatures and they can show core temperatures of body well. Therefore, when there are limitations for monitoring of body temperatures by nasopharyngeal route, the tympanic route can be a good replacement

Satisfaction evaluation of blood donors of Iranian Blood Transfusion Organization in 2003

Satisfaction of blood donors plays a critical role in providing safe and adequate blood supply for patients. This study aimed to evaluate the level of satisfaction of blood donors in Iranian Blood Transfusion Organization [IBTO]. This was a cross-sectional study with the involvement of 2508 blood donors selected in proportion to the average distribution of blood donors in different provinces of Iran. The random sampling method was used. Questionnaires were directly handed over to blood donors. There was a positive relationship between behavior of physicians or other care staff with satisfaction level of blood donors. Physical conditions of donation sites play an important role in satisfaction level of blood donors. There was a negative correlation between education level and satisfaction of blood donors; the higher the education level, the less the rate of satisfaction. There was not any significant difference in satisfaction of blood donors in terms of sex. Satisfaction rate of blood donors was higher among those referring to blood drives than those to blood centers. Satisfaction rate among repeat blood donors was more than twice that among first-time blood donors [PVO.04]. The highest satisfaction value is attributed to the behavior of the personnel involved in phlebotomy and physicians. The lowest satisfaction value pertained to accessibility of blood donor centers. Overall satisfaction rate was more than 50% showing a figure, higher than our previous estimation
