Comparison of Emergence Behavior in Pediatric Dental Patients Undergoing General Anesthesia with Sevoflurane versus Desflurane
Purpose: To determine which maintenance gas (sevoflurane versus desflurane) resulted in a faster emergence from general anesthesia and investigate the patient's emergence agitation. Methods: One group was maintained during general anesthesia with sevoflurane and the other with desflurane. Upon …

An Analysis Using State Space Global Coherence of Brain Dynamics in a Young Child Under Sevoflurane General Anesthesia
… (SSGC), to estimate global coherence (GC) during sevoflurane general anesthesia in an infant. Two different SSGC approaches were employed: one approach directly estimated GC from the data, while the other first estimated the covariance matrix and then used this matrix to compute GC. The SSGC …

The Effect of General Anaesthesia on Circadian Rhythms in Mice
… inhalational anaesthetic agents (isoflurane and sevoflurane), administered at different times of the day (circadian times, CTs), over a period of 24 hours. To do so, I collected data to construct a full phase response curve (PRC) for each anaesthetic agent. Animals received either a six-hour GA …

Shedding Light On General Anesthesia: Uncovering The Molecular Mechanisms For Propofol And Volatile Anesthetics
… the frequently administered volatile anesthetics sevoflurane and isoflurane, as well as the most commonly used intravenous anesthetic, propofol. A novel photoaffinity ligand for sevoflurane was validated and applied to uncover the unique mechanism of sevoflurane positive modulation of mammalian …

Hemodynamic Changes after Endotracheal Intubation with Colloid Loading in Patients with Cerebral Aneurysm
… 1946) 뇌동맥류 파열 방지를 위하여 혈역학적 변화를 최소화하는 것은 중요하다. Sevoflurane을 사용한 마취유도 시 적정농도는 2.5% (1.5 MAC)이라고 알려져 있으며 이 농도에서는 기도삽관에 의한 고혈압과 빈맥의 빈도는 줄일 수 있으나, 심한 저혈압을 초래할 수 있다. 뇌동맥류 환자 마취 유도시 심한 저혈압 또는 고혈압은 환자에게 치명적인 후유증을 야기할 수 있으므로 혈역학적 변화를 최소화 하는 것이 중요하다. 뇌동맥류 환자의 마취 유도시 혈역학적 변화를 최소화 하기 위하여 수술 전 충분한 수액 투여가 …

Risk Factors for Postoperative Cognitive Dysfunction in Older Adults Undergoing Major Noncardiac Surgery
… = 5.64, 95% CI = 1.35 – 30.22), and receiving sevoflurane for anesthesia (OR = 6.43, 95% CI = 1.49 – 34.66) were risk factors for POCD. Conclusion: The incidence of POCD in older adults is 15.9% three months after major noncardiac surgery. Risk factors for POCD were carrying the ApoE4 allele, …
