Bispektral indeks ve %95 spektral edge frekans ile halotan ve sevofluran anestezi derinliklerinin karşılaştırılması

Amaç: Bu çalışmanın amacı, bispektral indeks (BİS) ve % 95 spektral edge frekans (SEF) monitorizasyon sistemleri kullanarak, halotan ve sevofluran anestezi derinliklerinin değerlendirilmesidir. Yöntemler: 2001-2002 yılları arasında, yaşları 20 ile 60 arasında değişen, genel anestezi altında jinekolojik operasyon geçiren 40 hasta çalışmaya dahil edildi. Anestezi indüksiyonu Grup I hastalarda (n=20) halotan, Grup II hastalarda sevofluran ile konvansiyonel spontan inhalasyon indüksiyon metodu ile sağlandı. SEF ve BIS indeks değerleri kaydedildi. Bulgular: Her iki grupta entübasyon öncesi ve sonrası, cilt insizyon öncesi ve sonrası SEF değerleri, bazal değerlerine göre anlamlı derecede düşüktü (p

Comparison of the depth of anesthesia in sevoflurane and halothane anesthesia with bispectral index and 95% spectral edge frequency

Objective: The aim of the present study was to evaluate the depth of anesthesia provided by halothane or sevoflurane by using the bispectral index (BIS) and 95% spectral edge frequency (SEF) monitoring systems. Methods: Forty patients, between the ages of 20-60 years, scheduled for gynecological surgery under general anesthesia were studied between the years 2001-2002. Anesthesia induction was maintained by conventional spontaneous inhalation induction method with sevoflurane in the group I patients (n=20), with halothane in the group II patients (n=20). SEF and BİS index values were recorded. Results: In both groups, SEF values recorded before intubation, after intubation, before and after skin incision were significantly lower compared with values recorded at baseline (p
