For verifying the phase lag entropy as the tool for measurement of level of consciousness, the investigators compared phase lag entropy to bispectral index. Using Target-Controlled Infusion pump, propofol was infused for sedation during the spinal anesthesia. The investigators measured Observer's Assessment of Alertness/Sedation Scale as the propofol concentration rises. At the same time, The investigators observed phase lag entropy score and bispectral index score.

The purpose of this study is to learn more about an Entropy monitor that your anesthesiologist will be using.
To compare Bispectral index and entropy during maintenance of anesthesia
This project proposes to compare epidural versus spinal anesthesia in patients having liver resection surgery. The investigators hypothesize that spinal anesthesia will result in improved ...
The evaluation of the anesthetic depth monitoring using PLE(phase lage entropy) during propofol anesthesia
In major orthopaedic surgery of the lower extremities both continuous spinal anesthesia (CSA) and combined spinal epidural anesthesia (CSE) are safe and reliable anaesthesia methods. Our r...
Anesthesiologists at our hospital commonly administer spinal anesthesia for routine lumbar spine surgeries. Anecdotal impressions suggested that patients received fewer anesthesia-administered intrave...
Studies of spinal anesthesia in children are limited to a reduced group of high-risk patients and it remains relatively underused compared with general anesthesia in this age group in most institution...
Spinal anesthesia is administered for select procedures in the pediatric population and offers a safe alternative to general anesthesia. In this case series, we report loss of corneal and eyelash refl...
Spinal anesthesia is a form of regional anesthesia frequently used in various lower abdominal, orthopedic, obstetric operations such as a cesarean delivery. The most common local anesthetic used for s...
Spinal anesthesia is a safe and beneficial alternative to general anesthesia in infants (1, 2). We would like to share a prospective observational study of infants undergoing inguinal herniorrhaphy un...
The measure of that part of the heat or energy of a system which is not available to perform work. Entropy increases in all natural (spontaneous and irreversible) processes. (From Dorland, 28th ed)
A board-certified specialty of VETERINARY MEDICINE, requiring at least four years of special education, training, and practice of veterinary surgery after graduation from veterinary school. In the written, oral, and practical examinations candidates may choose either large or small animal surgery. (From AVMA Directory, 43d ed, p278)
Procedure in which an anesthetic is injected directly into the spinal cord.
A local anesthetic of the amide type now generally used for surface anesthesia. It is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted to spinal anesthesia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1006)
Percutaneous excision of a herniated or displaced intervertebral disk by posterolateral approach, always remaining outside the spinal canal. Percutaneous nucleotomy was first described by Hijikata in Japan in 1975. In 1985 Onik introduced automated percutaneous nucleotomy which consists in percutaneous aspiration of the nucleus pulposus. It is carried out under local anesthesia, thus reducing the surgical insult and requiring brief hospitalization, often performed on an outpatient basis. It appears to be a well-tolerated alternative to surgical diskectomy and chymopapain nucleolysis.
Anesthesia is the loss of feeling or sensation in all or part of the body. It may result from damage to nerves or can be induced by an anesthetist (a medical professional) using anesthetics such as thiopental or propofol or sevoflurane during a surgical ...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
An anesthesiologist (US English) or anaesthetist (British English) is a physician trained in anesthesia and perioperative medicine. Anesthesiologists are physicians who provide medical care to patients in a wide variety of (usually acute) situations. ...
