Clinical Trial
Total intravenous anesthesia for children undergoing brief diagnostic or therapeutic procedures.
To compare the quality of anesthesia with propofol, ketamine, or etomidate in children undergoing brief diagnostic or therapeutic procedures. ⋯ Anesthesia with propofol, ketamine, or etomidate is safe and efficacious for children undergoing brief procedures. Propofol is associated with a decreased incidence of postanesthetic agitation and vomiting. Its association with respiratory depression is confirmed.

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.

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.

Cardiopulmonary bypass (CPB) does not appear to cause excessive maternal risk, but the potential for fetal complications is of great concern. In general, operative intervention should be delayed until at least the second trimester. ⋯ This conflict is further complicated by maternal status changes that may accompany valvular disease or develop after CPB. The case described herein summarizes and discusses these conflicts.
