To determine how controversial the management of a number of clinical scenarios that are labeled as controversial (eg, how to induce anesthesia in the "open eye-full stomach" patient) are among those practicing anesthesia. ⋯ This survey of anesthesiologists regarding these controversial clinical scenarios showed that (a) most scenarios were in fact controversial amongst those in practice, and (b) there were disparities between whether a technique is believed to be acceptable practice and whether it would be used in one's own practice.

Case Reports Clinical Trial
Hemodynamic changes during laparoscopic cholecystectomy in patients with severe cardiac disease.
To evaluate the hemodynamic changes and need for pharmacologic interventions during laparoscopic cholecystectomy in patients with severe cardiac dysfunction. ⋯ Laparoscopic cholecystectomy in patients with severe cardiac dysfunction results in significant hemodynamic changes.

Case Reports
Pseudocholinesterase hyperactivity with succinylcholine resistance: an unusual cause of difficult intubation.
We describe a case of difficult intubation, possibly due to marked pseudocholinesterase hyperactivity that caused rapid inactivation of succinycholine. Possible causes of difficult intubation and pseudocholinesterase hyperactivity are discussed. ⋯ It is concluded that pseudocholinesterase hyperactivity may be a rare cause of difficult intubation. We recommend that pseudocholinesterase activity should be determined in all patients who appear to be resistant to the action of normal doses of succinylcholine or mivacurium.

Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative analgesia with parenteral opioids: does continuous delivery utilizing a transdermal opioid preparation affect analgesic efficacy or patient safety?
To compare, in patients who underwent major orthopedic surgical procedures, the efficacy of intravenous (IV) patient-controlled analgesia (PCA) with morphine combined with continuous administration of two doses of fentanyl or placebo via transdermal therapeutic system with fentanyl (TTSF) patches. ⋯ There is no significant advantage to the routine use of continuous transdermal opioid delivery in patients receiving IV PCA after major orthopedic surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
Pulse oximeter performance during desaturation and resaturation: a comparison of seven models.
To compare pulse oximeter performance during induced hypoxemia. ⋯ Most models of oximeters tested performed well when hemoglobin oxygen saturation was high, but all were inaccurate when SaO2 was approximately 75%. During induced hypoxemia, there were significant differences in the response times of oximeters tested, with no model demonstrably superior to others in all measures of performance.
