The effect of training level on opioid utilization efficiency.

Study Objective: This study focuses on residents' ability to predict opioid administration requirements and if improvement is made as learners progress. Residents request opioid from the pharmacy at the start of the day based on clinical assignment. Unused and wasted opioids are returned at the end of the day.

Smoking and perioperative outcomes.

Background: Patients are often concerned about the effects of smoking on perioperative risk. However, effective advice may be limited by the paucity of information about smoking and perioperative risk. Thus, our goal was to determine the effect of smoking on 30-day postoperative outcomes in noncardiac surgical patients.

Combined versus sequential injection of mepivacaine and ropivacaine for supraclavicular nerve blocks.

Background: An ideal local anesthetic with rapid onset and prolonged duration has yet to be developed. Clinicians use mixtures of local anesthetics in an attempt to combine their advantages. We tested the hypothesis that sequential supraclavicular injection of 1.

A nomogram for predicting surgical complications in bariatric surgery patients.

Background: To minimize morbidity and mortality associated with surgery risks in the obese patient, algorithms offer planning operative strategy. Because these algorithms often classify patients based on inadequate category granularity, outcomes may not be predicted accurately. We reviewed patient factors and patient outcomes for those who had undergone bariatric surgical procedures to determine relationships and developed a nomogram to calculate individualized patient risk.
