To measure the start time for the first case of the day and the turnover times for subsequent cases in the operating rooms (ORs) at an academic hospital. ⋯ The scheduled start time for the first case of the day was generally the time the patient was brought into the OR. Because of the variable amount of time required for anesthesia induction and surgical preparation and draping, incision occurred 21 to 49 minutes later. The time between cases when no surgery was occurring was significantly longer than room turnover time because of the need to wake up one patient and induce the following patient. Because of a lack of standardized definitions, there is probably a strong perceptual difference among anesthesiologists, OR nurses, and surgeons when viewing start and turnover times. At our own teaching institution, shortening turnover times would increase the amount of elective OR time available, but the impact would not be significant because the number of procedures done per OR each day is low.

To determine whether the window design of pencil-point spinal needles leads to deformation under lateral or axial loading conditions. ⋯ The Sprotte needles have an inherent design weakness to lateral and axial pressure, which may result in a greater number of needle tip deformations upon needle insertion. The nature of this deformation may result in difficulty in needle withdrawal and possibly fracture of the needle tip.

To determine the impact of a cost containment program on the use of volatile anesthetics and neuromuscular blocking drugs. ⋯ Concerted educational efforts can decrease the per case expenditures for both volatile anesthetic drugs and neuromuscular blocking drugs.

Comparative Study Clinical Trial Controlled Clinical Trial
Epidural administration of liposome-associated bupivacaine for the management of postsurgical pain: a first study.
To explore the influence of liposomes on the pharmacodynamic action of bupivacaine and to determine whether postsurgical analgesic advantages can be obtained from epidural delivery of liposomal bupivacaine compared with the current formulation. ⋯ The liposomal formulation of bupivacaine increased duration of analgesia without motor block or adverse side effects.

Comparative Study
Predictive accuracy of midazolam in adult patients scheduled for coronary surgery.
To evaluate the predictive accuracy of midazolam during cardiac anesthesia so as to orient the selection of the most appropriate pharmacokinetic model for use in a computer-assisted continuous-infusion system. ⋯ Two of the 3 pharmacokinetic data sets of midazolam studied may be selected when using a computer-assisted infusion system in adult coronary patients.
