Meta Analysis
The incidence of aspiration associated with the laryngeal mask airway: a meta-analysis of published literature.
To determine the incidence of pulmonary aspiration with the laryngeal mask airway (LMA). ⋯ The evidence to date suggests that the pulmonary aspiration with the LMA is uncommon and comparable to that for outpatient anesthesia with the face mask and tracheal tube. Meticulous attention to selection of low-risk patients and appropriate operative procedures and avoidance of light anesthesia should reduce the incidence even further.

The successful management of major conduction anesthesia in a patient with Klippel-Trenaunay syndrome is discussed. This case illustrates that major conduction anesthesia can be safely used if proper imaging studies are obtained, if one is aware of the underlying disease process, and if there is no port wine lesion in the dermatomal area corresponding to the spinal segment where the needle is to be inserted.

Biography Historical Article
Davy comes to America: Woodhouse, Barton, and the nitrous oxide crossing.
In the final decade of the eighteenth century, a new method of medical treatment appeared in England when physician Thomas Beddoes developed a systematic application of Joseph Priestley's "factitious airs", or gases, to treat consumptive patients. Supported by peers such as Erasmus Darwin and using applications designed for him by James Watt and other inventors, Beddoes combined technological innovation and gas inhalation in an attempt to cure his patients. Late in the decade Beddoes hired young Humphry Davy as his assistant; Davy quickly added nitrous oxide to the armamentarium. ⋯ Such intermittent experimentation continued in the United States and Europe until Horace Well's public demonstration of ether inhalation in January 1845. This paper describes how nitrous oxide inhalation survived in America through the work of Woodhouse and Wells. Traveling showmen like Samuel Colt and Gardner Quincy Colton demonstrated the gas' effects at popular lectures.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol-based anesthesia as compared with standard anesthetic techniques for middle ear surgery.
To determine if a total intravenous (i.v.) technique with propofol and fentanyl is superior to isoflurane anesthesia in patients undergoing middle ear surgery. ⋯ Propofol-fentanyl seems to be a better anesthetic than isoflurane-fentanyl in reducing the incidence of nausea and vomiting after middle ear surgery. Through the addition of droperidol to the isoflurane anesthetic seemed as effective, emergence from anesthesia was slower. For middle ear surgeries producing emesis, propofol-based anesthetics produced a rapid emergence with less nausea and vomiting.

Clinical Trial
Computerized axial tomography to define the distribution of solution after stellate ganglion nerve block.
To define the spread of local anesthetic after C6 stellate ganglion nerve block using computerized axial tomography (CAT). ⋯ Solutions injected for C6 stellate ganglion nerve block concentrate medial to the stellate ganglion at T1. Thus, they must produce upper extremity sympathectomy by a mechanism other than contact with the ganglion.
