Filter by:The World Health Organisation recommends that all patients having a general anaesthetic for surgery should be given 80% oxygen as this might reduce their risk of getting an infection after their operation. However there remains a lot of uncertainty about how much oxygen patients should be given whilst undergoing surgery. In other areas of medicine evidence is slowly emerging to suggest that giving less oxygen may be as safe or even safer than giving high amounts of oxygen (e.g. after a heart attack, patients unnecessarily given oxygen seem to do worse than those given air). The amount of oxygen currently given to patients having surgery varies widely; in a recent study of almost 400 procedures across 29 hospitals, we found values ranged from below 30% to almost 100% oxygen. The aim of this research is to explore if giving less oxygen will generate less strain on parts of the body, particularly the lungs as they are always exposed to all of the oxygen that enters the body. Participants undergoing major elective surgical procedures will be randomised to receive either 80%, 55% or 30% throughout their general anaesthetic and levels of inflammation, oxidative stress and perioperative recovery will all be measured for upto 7 days after surgery.
Most gastrointestinal endoscopic procedures are now performed with sedation and analgesia. Sedation and analgesia affects the quality of the procedure, patient co-operation and compliance as well as endoscopist's satisfaction. A wide variety of procedures have been reported worldwide for anesthesia during gastrointestinal endoscopy in adults. The current survey was primarily designed to provide national data on the attidutes and behaviors of gastroentorologist on anesthesia procedures in endoscopy units in Turkey.
Renal transplantation is now recognized as a treatment of choice for patients with end-stage renal disease. An adequate anesthetic technique should achieve hemodynamic stability and enhance perfusion of the transplanted kidney. The aim of this study is to assess the use & effects of continuous spinal anesthesia for kidney transplantation recipients, compared with balanced general anesthesia.
The main goal of this study is to compare wound infiltration with ketorolac versus lidocaine for postoperative analgesia in total abdominal hystrectomy (TAH) operation.
This study,will evaluate the efficacy of ultrasound (US)-guided subcostal oblique TAP block together with IV infusion of Dexmedetomidine and fentanyl as a type of multimodal analgesic regimen in comparison with IV fentanyl based analgesia only in live liver donors.
This study compares the extubation time between total intravenous anesthesia guided by Bispectral Index with spinal anesthesia with minimal opioid dose for cardiac surgery.

There is considerable evidence that most general anaesthetics modulate brain development in animal studies. The impact is greater with longer durations of exposure and in younger animals. There is great controversy over whether or not these animal data are relevant to human clinical scenarios. The changes seen in preclinical studies are greatest with GABA agonists and NMDA antagonists such as volatile anaesthetics (eg sevoflurane), propofol, midazolam, ketamine, and nitrous oxide. There is less evidence for an effect with opioid (such as remifentanil) or with alpha 2 agonists (such as dexmedetomidine). Some, but not all, human cohort studies show an association between exposure to anaesthesia in infancy or early childhood and later changes in cognitive tests, school performance or risk of developing neurodevelopmental disorders. The evidence is weak due to possible confounding. A recent well designed cohort study (the PANDA study) comparing young children that had hernia repair to their siblings found no evidence for a difference in a range of detailed neuropsychological tests. In that study most children were exposed to up to two hours of anaesthesia. The only trial (the GAS trial) has compared children having hernia repair under regional or general anesthesia and has found no evidence for a difference in neurodevelopment when tested at two years of age. The GAS and PANDA studies confirm the animal data that short exposure is unlikely to cause any neurodevelopmental impact. The impact of longer exposures is still unknown. In humans the strongest evidence for an association between surgery and poor neurodevelopmental outcome is in infants having major surgery. However, this is also the group where confounding is most likely. The aim of our study is to see if a new combination of anaesthetic drugs results in a better long-term developmental outcome than the current standard of care for children having anaesthesia expected to last 2 hours or longer. Children will be randomised to receive either a low dose sevoflurane/remifentanil/dexmedetomidine or standard dose sevoflurane anaesthetic. They will receive a neurodevelopmental assessment at 3 years of age to assess global cognitive function.
This study will explore the feasibility of an idea to use standard, FDA-approved patient monitors to detect ventilatory depression and then play a recorded nurse's voice to prompt patients by name to breathe. The voice prompt will occur in addition to when the traditional alarms are sounded by the monitors. The study device consists of commercially available physiologic monitors, a speaker, and a laptop computer. The physiologic monitors include a pulse oximeter with a motion sensor, capnometer, and nasal airway pressure sensor (built into a nasal cannula). Nasal pressure is a commonly used clinical monitor for sleep apnea detection during polysomnography testing in sleep labs.
The aim of this observational study is to create a data base to extract feature of fast-acting drugs that can be monitor in real time to design control strategies based on high order sliding mode controller to create a robust drug infusion system.
