Use of ProSeal laryngeal mask airway in 2114 adult patients: a prospective study.
There have been numerous studies published on the ProSeal laryngeal mask airway (PLMA). However, few have investigated its utility in a large practice setting. We sought to gather comprehensive data about the characteristics, efficacy, and safety of its use by a representative group of anesthesiologists working at a teaching center. ⋯ This study demonstrates that airway management using the PLMA is safe and effective in a general practice setting. The results support the assumption that a correctly positioned PLMA can protect from pulmonary aspiration of regurgitate gastric fluid. The data also support use of the PLMA for the management of the difficult airway.

Case ReportsAnesthetic management of parturients with congenitally corrected transposition of the great arteries: three cases and a review of the literature.
Women with congenitally corrected transposition of the great arteries (CCTGA) have a propensity for congestive heart failure and cardiac dysrhythmias during pregnancy, labor, and delivery. We report the successful obstetric and anesthetic management of three women with CCTGA, review the pertinent medical literature, and discuss important issues surrounding the anesthetic management of parturients with CCTGA.

Oxygen consumption of a pneumatically controlled ventilator in a field anesthesia machine.
Field anesthesia machines (FAM) have been developed for remote locations where reliable supplies of compressed medical gases or electricity may be absent. In place of electricity, pneumatically controlled ventilators use compressed gas to power timing circuitry and actuate valves. We sought to determine the total O(2) consumption and ventilator gas consumption (drive gas [DG] plus pneumatic control [PC] gas) of a FAM's pneumatically controlled ventilator in mechanical models of high (HC) and low (LC) total thoracic compliance. ⋯ To prepare for loss of central DG supply, patient safety will be improved by estimating cylinder duration for low total thoracic compliance. Using data from the smaller compliance and greatest V(T) model (LC-1000), a full O(2) E cylinder would be depleted in <42 min, whereas a full H cylinder would last approximately 433 min.

Operating room nursing directors' influence on anesthesia group operating room productivity.
Implementation of initiatives to increase anesthesia group productivity depends not just on anesthesia groups, but on operating room (OR) nursing administration. OR nursing directors may encourage organizational change based on the needs of their hospitals and nurses. These changes may differ from those that would increase the anesthesia group's productivity. We assessed reward structures using (A) letters of nomination for the "OR Manager of the Year" award offered annually by the publication OR Manager, and (B) data from a salary/career survey of OR directors by the same publication. ⋯ Through (A) organizational constituencies, and (B) compensation, many US OR nursing directors likely are encouraged to enhance relations with nursing staff, not to champion organizational initiatives that would reduce under-utilized OR time and OR nursing labor costs. Resulting decisions can differ from those that would increase the productivity (profit) of the anesthesia group. Anesthesia groups need to champion initiatives to increase anesthesia productivity, while being sensitive to institutional expectations of nursing directors.
