The purpose of this study is to find out the proper amount of a drug called dexmedetomidine added to the local anesthetic drug called lidocaine to prolong the time and effect of pain relief provided for surgery. Dexmedetomidine (trade name Precedex) is approved by U.S. Food and Drug Administration (FDA) and indicated for sedation (calming effect). It has both pain relieving and calming effects when added to lidocaine. In the past, addition of higher amounts of dexmedetomidine to lidocaine decreased blood pressure and heart rate. The investigators plan to study the effect of lower amounts of dexmedetomidine to achieve the same level and duration of pain relief without reduction of blood pressure and heart rate.
The purpose of this study is to determine the conducting ability of distal extremity nerves after a supraclavicular brachial plexus nerve block (with local anesthetic) has been placed at a more proximal location in the upper extremity.
The primary objective of this prospective, descriptive study is to evaluate the success rate of the retroclavicular brachial plexus block and catheter placement in 60 adult patients undergoing hand, wrist, or forearm surgery. The investigators will also evaluate any difficulties performing the procedure, the onset time and distribution of the block, incidence of adverse events, and patient's acceptance of the block.
Identification of the genetic polymorphisms that could be correlated either with a better clinical response or with a major predisposition of patients to develop tolerance and/or side effects to the treatment with morphine.
Primary Objective: Conduct a prospective, observational pilot study that assesses the frequency and severity of anesthesia charting fidelity weaknesses in three separate clinical environments (Cardiac surgical operating room, cardiac surgical intensive care unit, and electrophysiology laboratory) as assessed by a customized error scoring system that focuses on the magnitude of errors among multiple continuous, categorical and dichotomous variables. The errors are being assessed in order to identify the most common charting inaccuracies so that target areas appropriate for testing of improvement strategies may be isolated.
Tetracaine gel 4% is a topical anaesthetic gel commonly used in the UK that contains 40 mg of tetracaine base per gram. Adequate anaesthesia can usually be achieved following a 30 minute application time for venopuncture and a 45 minute application time for venous cannulation. The hypothesis is that Rapydan medicated plaster is more effective than tetracaine gel in preventing venous cannulation related pain when applied for the recommended treatment durations of 30 minutes and 45 minutes respectively.
