Filter by:Rocuronium block neuromuscular transmission at the neuromuscular junction, causing paralysis of the affected skeletal muscles. There have been several studies reported positive relationship between muscle mass and amount of neuromuscular junction. The purpose of this study is to find relationship between muscle mass and muscle relaxation time.
Postoperative delirium occurs in up to 65% of elders undergoing surgery for repair of a hip fracture and this complication is independently associated with increased morbidity, mortality, length of hospital stay, and placement in long-term care institutions. To date, the only intervention shown to be effective at minimizing postoperative delirium is a proactive geriatric consultation. This prospective randomized clinical trial will randomize 160 adults, aged 65 years or older, to either optimized general anesthesia or usual general anesthesia care for hip fracture surgery to determine if the optimized anesthesia management reduces the severity of postoperative delirium.
This prospective randomized is designed to evaluate the safety and efficacy of hernia repairs using local anesthesia compared with those using general anesthesia for patients with incarcerated hernia.
Dexmedetomidine, a selective alpha-2 agonist agent used for maintaining sedation in intensive care patients in receipt of mechanical ventilation, is being increasingly utilized in anaesthesia practice for facilitating anaesthesia depth as an adjunct to base anaesthetics (intravenous; propofol: inhalational; sevoflurane, desflurane). The investigators intend to assess the anaesthetic potential of dexmedetomidine in controlled anaesthesia settings empowered by the use of an objective, patient response based, safe, efficient, and patented closed loop anaesthesia delivery system (CLADS). CLADS functions on control of processed EEG response parameter captured from anaesthetized patients with the help of a BIS- monitor, which is continuously fed into a automated drug infusion pump. The infusion pump then accordingly delivers the anaesthetic drug to the patients based on pharmacodynamic requirements. If dexmedetomidine has anaesthesia potential then it is likely that propofol use delivered by CLADS can be reduced further. In addition the effect of two drugs (viz, base agent-propofol plus adjunct agent-dexmedetomidine) on different receptor site within the brain would help gain greater anaesthetic depth consistency as well as a lower incidence of intraoperative patient awareness. This prospective randomized two-arm study aims to assess effect of the use of dexmedetomidine on propofol requirements (primary objective), anaesthesia depth consistency, and intraoperative patient awareness (secondary objectives).
This study is a single-center, prospective, randomized, controlled trial. To investigate if preoperative using of eye patch will decrease emergence agitation, and to provide a better method of decreasing emergence agitation to pediatric ophthalmic anesthesiologists.
The study is carried out in a prospectively randomly controlled way. In the context of acknowledgement and understanding from parents, by comparing with traditional process(no anesthesia), lidocaine surface anesthesia is randomly selected. All children will be evaluated by the FLACC (The face, legs, activity, cry, consolability behavioral tool) scale to quantitatively assess degree of pain during lumbar puncture. Time and success rate of the lumber puncture will be recorded and analyzed. A questionnaire about bad memory during lumbar puncture for all parents and children will be investigated in order to establish an optimized lumbar puncture management process.
Ethyl chloride vapocoolant sprays provide transient skin anesthesia within seconds of application. The current investigation aim is to compare the effect of ethyl chloride based vapocoolant spray to placebo in reducing pain associated with arterial puncture for gasometry determinations. The investigators will conduce a double-blind randomized placebo-controlled trial at Emergency Department. We will enroll patients who come to Emergency Department who need an arterial gasometry determination. Patients will be randomized to intervention-group (ethyl chloride vapocoolant sprays will be usad before arterial puncture) or to placebo-group (alcohol spray as placebo will be used before arterial puncture.) and after the puncture they will rate their pain using a 10 points visual analogue scale.
The BIS Index, one of the VISTA Monitor output parameters, may be used as an aid in monitoring the effects of certain anesthetic agents;and its usage with certain anesthetic agents may be associated with a reduction in primary anesthetic use and a reduction in emergence and recovery time. However, this equipment does not give the proper anesthetic depth index is a number of experimental results have been reported. Therefore, the investigators study that the BIS VISTA receives an electroencephalogram (EEG) obtained through the depth of anesthesia monitors brain waves to collect statistical data, through mathematical analysis to analyze the exact correlation between the patient's brain waves and the depth of anesthesia.
The purpose of this study is to determine whether phenylephrine infusion are effective in the prevention of hypotension after changing position to beach chair position during general anesthesia for shoulder arthroscopic surgery. Investigators hypothesized that by increasing arterial blood pressure with phenylephrine infusion, incidence of hypotension would be decreased.
The purpose of this study is to find difference in Minimum Alveolar Concentration(MAC) for maintaining Bispectral Index (BIS) below 50 between chronic opioid users and opioid naive patients.
