Types of Studies We reviewed the article and discussed the anesthesia history as to why the use of CO2 disappeared. We made a comprehensive review of the types of studies.

MetaAnalysis We discussed some standard limitations of a retrospective study such as the Welch et al 2009 paper. One limitation is that the data is imcomplete. Here, weight was not included; this information would have been interesting to see. A retrospective study can only make associations and cannot address mechanisms. It was noted that it is very important to do a physical exam as part of your preop assessment and postop assessment. We discussed the role of "advisories". It was also noted that there is no real evidence behind much of the advisory information on preoperative nerve injuries. The 2011 paper does show that there is very little info on the subject yet we have OR personnel who are very attuned to padding/ positioning the patient. An advisory is noted to be mostly opinion. The final aspect of the JC involved a review of meta analysis. Nerve injury associated with anesthesia: a closed claims analysis. Cheney FW, Domino KB, Caplan RA, Posner KL.

Ethics Here are some questions to ponder: Is the study large enough? How do you define optimal? Are the results generalizable to our practice? What is the role of iv agents (ketamine, gabapentin, etc.)? Dr. Zeqo gave a nice concise review of the article. We saw that it was important to identify the primary outcome is in a study and at what time point. The researchers looked at VAS score and another pain score. This article looked at 5 different groups: this requires a correction factor for multiple measurements. If the analysis of variance shows a significant difference among the groups, then a posthoc test must be done to determine which groups are significantly different. We also reviewed the editorial "Do we have the Tools to Prevent Phantom Limb pain?". Dr. Milloul gave us a very complete historical review of Ethics in Research: from the Nuremberg code of 1948 through the violations seen recently in anesthesia research. It is important to remember that we should always be ethical in our life choices. Dr. Glass also informed us that the department will have a computer program to check all article submissions for originality. Optimized perioperative analgesia reduces chronic phantom limb pain intensity, prevalence, and frequency: a prospective, randomized, clinical trial.

Presentations
Drs Siddiqui, Florence and Rampil reviewed the article on Inspiratory Oxygen Fraction and Postoperative Complications in Obese patients. They discussed the relevance of BMI. In opting to study obese patients, the researchers had a greater chance of a detecting a difference in outcome. They also noted that some risks of BMI were not specifically addressed in the study: obese patients have an increased duration of surgery and a larger incision wound. Interestingly, it was noted that obese patients had a larger average rate of infection of 30%. This study did not detect any significant differences. However, the study appeared to be underpowered and probably should not have been published. It was published, however, probably because the study design involved a large consortium. Dr. Foster gave a terrific and concise talk about giving oral presentations. She made many good points. For example, "tell them what you are going to say, tell them, and then tell them what you said." One should also beware of using small fonts and poor color choices on slides. This information will definitely be useful to us no matter which side of the lecture podium we are standing. Survey study of anesthesiologists' and surgeons' ordering of unnecessary preoperative laboratory tests.
