RESUMO
The Louisiana State University Health Sciences Center Department of Anesthesiology performed an analysis of anesthesia practice and needs within the State of Louisiana. The State of Louisiana currently has approximately 300 practicing anesthesiologists (physicians), 700 certified registered nurse anesthetists (CRNAs), and does not currently utilize anesthesiologist assistants (AAs). Approximately 500,000 anesthesia encounters occur annually in Louisiana. Although there is a recognized critical shortage of anesthesiologists nationally, this document will focus mainly on the issue of mid-level providers of anesthesia services. The overwhelming majority of surgical and obstetric procedures is performed using the anesthesia care team approach both nationally and in the State of Louisiana. Within the anesthesia care team model, the practice of certified registered nurse anesthetists and anesthesiologist assistants are interchangeable, and both would meet the need for mid-level anesthesia providers in the State of Louisiana.

The availability of relatively low-cost, portable ultrasound units has increased interest among non-radiologists in performing image-guided central venous cannulation, especially in high-risk patients. The essential elements of this relatively simple method of increasing the success and safety of internal jugular cannulation are presented.

Patient-controlled sedation (PCS) with propofol has been shown to be an effective means of conscious sedation during monitored anesthesia care. The purpose of this study was to assess both the intraoperative conduct and postoperative recovery of patients receiving propofol for conscious sedation, randomized to either PCS or anesthetist-controlled sedation (ACS). Forty-three patients scheduled for outpatient procedures requiring monitored anesthesia care were randomized to PCS or ACS. Both groups received an initial bolus of propofol 0.5 mg/kg and fentanyl 1 microgram/kg i.v., followed by an identical background infusion of propofol 50 micrograms/kg per minute. Subsequent doses of propofol 30 mg i.v. were either self-administered (PCS) or administered at the discretion of the anesthetist (ACS). Variables measuring hemodynamics, ventilation, saturation, and level of sedation were measured at baseline, after initial bolus of propofol and fentanyl, after skin incision, at last stitch, at admission to recovery, and 1 hour later. More propofol was used by the PCS group (P < 0.05). Finger-tapping was slower and responsiveness scores were lower in the PCS group at the end of the procedure (P < 0.05). More patients in the PCS group required oxygen supplementation (saturation < 90%) on admission to recovery (P < 0.05). At 1 hour after recovery admission, however, there were no differences between groups. These results indicate that when patients determine their own sedation, they are more sedated at the end of a procedure than when the anesthetist determines the level of sedation.

We have shown that transtracheal jet ventilation can be used safely and effectively when removing a foreign body from the airway. In some cases, it may be wise to choose this method of ventilation initially, thus avoiding the difficulties associated with more conventional modes of controlled ventilation. This is especially true when the potential for loss of the airway during the procedure is significant. This technique also allows the bronchoscopist the benefit of unimpeded access to the airway and adequate uninterrupted time for his operative procedure.
