Abstract: Lake of information about anaesthesia and fear of post operation consciousness, pain, nausea and vomiting increases patient`s anxiety. There are various reports about patient`s desire for preoperational information in Iran and other countries, but we don`t find any study related to anesthesiologist`s view about patient`s needs before anaesthesia and operation. This descriptive (cross- sectional) study was done in 2005 on 110 anesthesiologists working in hospitals of Mazandaran province. Questionnaire containing 4 questions about demographic and 18 questions related to anaesthesia was prepared. Attitude of the anesthesiologists was studied by dividing in 4 categories based on Likert rating scale as follow: strongly agree, agree, particularly agree, disagree and strongly disagree. The obtained data were shown in table; chi-square test was used for the statistical analysis of the data. Results of this study showed that the most positive attitude of anesthesiologists about patient teaching was related to the proper explanation about duration of N.P.O before operation (97.3%) and 52.7% were against about giving explanation of the during and post operation possible problems. In this regard no significant difference was observed between educational and non educational hospitals (p<0.018). No significant view point difference was observed between anesthesiologists at different level of education (p<0.07). Considering the positive attitude of the anesthesiologists towards education to preoperational patients, it is recommended that such education be implemented and the patients be charged for preoperational consultation. In order to give explanation about anaesthesia at proper time, when needed.
