Abstract

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

Abstract

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
