چکیده

مقدمه: تعیین عمق بیهوشی و یا کاهش سطح هوشیاری در بیماران مسموم مراجعه کننده به بیمارستان، یکی از مسایل مهم در تعیین نیاز بیماران به لوله‌گذاری می‌باشد. هدف از انجام مطالعه‌ی حاضر، بررسی ارتباط بین نمره‌ی Bispectral index (BIS) با نمره‌ی Glasgow coma scale (GCS) در افراد مسموم با کاهش سطح هوشیاری نیازمند به لوله‌‌گذاری تراشه بود.روش‌ها: مطالعه‌ی حاضر بر روی 24 فرد مسموم مراجعه کننده به بخش مسمومین بیمارستان نور اصفهان انجام گرفت. نمره‌ی سطح هوشیاری، با استفاده از GCS و BIS در دو نوبت یکی در بدو ورود و دیگری در زمان نیاز به لوله‌گذاری ثبت شد. در نهایت، اطلاعات جمع‌آوری شده در نرم‌افزار SPSS نسخه‌ی 20، وارد و نتایج با استفاده از آزمون‌های Independent t، همبستگی Pearson و تحلیل Regression مقایسه شد.یافته‌ها: همبستگی معنی‌داری میان BIS و GCS در بدو ورود وجود داشت؛ به گونه‌ای که در بیماران با افزایش BIS، GCS نیز افزایش یافت (050/0 > P) و همچنین، رابطه‌ی مستقیم و معنی‌داری میان BIS در بدو ورود و در هنگام لوله‌گذاری تراشه وجود داشت (001/0 > P).نتیجه‌گیری: با توجه به میزان بسیار کم تغییرات همودینامیک در مطالعه‌ی حاضر و همچنین، این مسأله که تغییرات BIS نسبت به GCS کمتر بود، می‌توان دریافت که BIS، بیشتر نشان دهنده‌ی تغییرات همودینامیک می‌باشد و بیشتر عوارض در رابطه با لوله‌گذاری تراشه را نشان می‌دهد.

چکیده [English]

Background: Determining the depth of anesthesia or loss of consciousness in poisoned patients admitted to hospitals is one of the most important issues in determining the necessity to tracheal intubation. This study aimed to investigate the relationship between the scores of Bispectral index (BIS) and Glasgow coma scale (GCS) in poisoned patients with loss of consciousness requiring tracheal intubation.Methods: 24 poisoned patients referred to Noor Hospital in Isfahan, Iran were enrolled. The level of consciousness was recorded using the GCS and BIS in two times, one at the beginning and the other at the time of tracheal intubation. Finally, the data were analyzed using independent-t and Pearson's correlation and regression analysis tests via SPSS software.Findings: There was a significant correlation between the BIS and GCS scores at admission that as BIS increased in patients, the GCS score increased, too (P = 0.050). In addition, a significant relationship was found between the BIS scores at the admission and during tracheal intubation (P = 0.001).Conclusion: As in our study, the hemodynamic changes was very low and the BIS changes was lower than the GCS, we can understand that BIS is more indicative in showing hemodynamic changes and complications associated with tracheal intubation.
