Anesthetics given to patients during surgery could cause an increase in pain following the procedure, according a new study. Published in the June 23 issue of the Proceedings of the National Academy of Sciences, the study is the first to scientifically explain what doctors have noticed in clinics, researchers said. They hope their findings will lead to the development of new anesthetics that don't cause post-surgical pain. Gerard Ahern of Georgetown University Medical Center in...

By Hong, Jeong-Yeon Lim, Kyung T Background and Objective: Surgical stress and general anesthesia suppress immune function. Preemptive epidural analgesia can affect the perioperative immune responses, and influence cancer management. Methods: Forty women undergoing elective laparoscopic radical hysterectomy for cervical cancer were allocated to this prospective, randomized, double-blind trial. Before inducing anesthesia, 2 mg morphine dissolved in 15 mL of 1 % lidocaine (preemptive group)...

'McSleepy' hopes to revolutionize anesthesia practiceResearchers at McGill University and the McGill University Health Centre (MUHC) have performed the world's first totally automated administration of an anesthetic. Nicknamed "McSleepy," the new system developed by the researchers administers drugs for general anesthesia and monitors their separate effects completely automatically, with no manual intervention."We have been working on closed-loop systems, where drugs are administered, their...

Researchers at the University of California say low doses of a commonly-used anesthetic could prevent the formation of painful memories. New Scientist magazine reported that scientists have found that sevoflurane gas stopped patients remembering "emotive" images. Scans showed the gas interfered with signals between two key areas of the brain. This could eventually help eradicate rare instances of anesthetized patients remembering the full horrors of their surgery. Anesthetic drugs are...

Researchers at Washington University School of Medicine in St. Louis reported disappointing results in a study on the prevention of anesthesia awareness,  which occurs when a patient under general anesthesia remains awake during surgery.Patients in this state can often recall surroundings, events, and pain related to the surgery, even though they are under general anesthesia.  Because neuromuscular blocking agents are routinely used with general anesthesia, patients are often unable...

KENILWORTH, N.J., March 11 /PRNewswire-FirstCall/ -- Schering-Plough today announced that the U.S. Food and Drug Administration (FDA) Advisory Committee on Anesthetics and Life Support has recommended sugammadex for approval. After reviewing data on the safety and efficacy of the medication, the committee unanimously recommended approval of the company's application for marketing. The FDA is not bound by the committee's recommendations; however, they usually are considered carefully...

By Modi, Neil Shaw, Steve; Allman, Keith; Simcock, Peter KEYWORDS Anaesthesia / Anxiety / Cataract / Handholder / Pain / Satisfaction To assess factors influencing perception of pain, anxiety and overall satisfaction during local anaesthetic cataract surgery an audit was carried out at the West of England Eye Unit. Patients receiving sub-Tenons after previous peribulbar anaesthesia had significantly higher pain scores. Patient satisfaction was significantly higher when a handholder was...

By Kocum, A Turkoz, A; Ulger, H; Sener, M; Arslan, G SUMMARY Ropivacaine is potentially less cardiotoxic and neurotoxic than bupivacaine. The aim of this study was to compare the effectiveness of ropivacaine 0.25% and bupivacaine 0.25% for surgical anaesthesia and postoperative analgesia during lumbar plexus and sciatic nerve block in high-risk patients. We performed combined lumbar plexus and sciatic nerve blockade on 62 consecutive ASA III or IV patients undergoing unilateral hip or femur...

U.S. researchers have adapted real-time 3-D ultrasound imaging devices, enabling them to watch as they use a needle with anesthetic to numb nerves. The anesthesiologists have demonstrated the benefits of real-time 3-D ultrasound in nerve blockade in more than 150 surgeries of varied types. The latest case study, reported in Anesthesia & Analgesia, describes how they used 3-D ultrasound to find the sciatic nerve behind the thigh of a woman who needed major reconstructive surgery on...

Ten genes that may make patients more or less susceptible to a common anesthetic agent have been identified by researchers using tiny worms and sophisticated technology that eliminates the activity of individual genes. "We are anesthetizing 25 million patients a year in the United States alone; we put them to sleep and wake them up and we still don't know a lot about why it happens," said Dr. Steffen E. Meiler, vice chair of research for the Medical College of Georgia Department of...
