Prevalence and predictive factors of urinary retention assessed by ultrasound in the immediate post-anesthetic period.

Background And Objectives: Urinary retention is a common condition in the post-anesthetic care unit (PACU). Vesical overdistension and consequent damage of the detrusor muscle of the urinary bladder represent situations that can be prevented. The ultrasound allows the reliable measurement of the urinary volume, determining the prevalence of postoperative vesical distension.

[Effective anesthetic volumes in sciatic nerve block: comparison between the parasacral and infragluteal-parabiceps approaches with 0.5% bupivacaine with adrenaline and 0.5% ropivacaine].

Background And Objectives: The volume and mass of local anesthetics (LA) affect the success rate of peripheral nerve blocks. Thus, the main objective of this study was to determine the volumes of local anesthetics in parasacral and infragluteal-parabiceps sciatic nerve block (SNB).

Methods: One hundred and one patients undergoing infragluteal-parabiceps or parasacral SNB with 0.

An instrument designed for faculty supervision evaluation by anesthesia residents and its psychometric properties.

Background And Objectives: We aimed 1) to develop a valid and reliable instrument for faculty supervision evaluation by anesthesia residents and 2) to disclose the sources of error in residents' ratings.

Methods: A qualitative study involving residents and faculty identified constructs of supervisory ability, which were entered as items in a measurement instrument used by 19 residents to evaluate 39 instructors during a 6-mo period. The instrument was psychometrically tested under classical item and generalizability theories.

Preanesthetic clinical problems of morbidly obese patients submitted to bariatric surgery: comparison with non-obese patiens.

Background And Objectives: Morbid obesity is associated to clinical problems responsible for decreased life expectancy. Morbidly obese patients are candidates to gastric bypass and pose new challenges to the anesthesiologist. This study compared the prevalence of clinical problems among morbidly obese patients submitted to bariatric surgery to non-obese patients submitted to other elective surgical procedures.
