ABSTRACT
A common approach to blood pressure management in the operating room is to keep the intraoperative, pressures within 20% of baseline blood pressure. One question that arises from this recommendation is; what is a patient's true baseline blood pressure? In order to get a more precise definition of baseline blood pressure, a comparison of the first operating room blood pressure was made with the blood pressure taken in a preoperative holding area before surgery, and the blood pressure taken in pre-surgical testing. (before day of surgery). A database of 2087 adult general anesthesia cases was generated, which contained the blood pressure (BP) in the pre-surgical testing clinic, the first BP in preoperative holding on the day of surgery, and the first BP in the operating room. Comparisons were made between the blood pressures taken at each phase of care. All components of BP taken in the OR were statistically significantly higher (p<0.001 for all comparisons) than in either PST or the holding area, while the BP in the latter locations were not significantly different. This blood pressure difference persists whether or not the patient is taking antihypertensive medications. The higher blood pressure measured in the operating rooms precludes using this measurement to determine baseline blood pressure. Blood pressures taken prior to arrival in the operating room are similar to blood pressures taken before the day of surgery. Blood pressure measurements taken prior to entrance in the operating room can be used to determine baseline blood pressure.

Our planet is in the midst of an environmental crisis. Government and international agencies such as the Intergovernmental Panel on Climate Change urge radical and transformative change at every level of how we conduct our personal and professional lives. The health care industry contributes to climate change. According to a study from the University of Chicago, the health care sector accounts for 8% of the United States' total greenhouse gas emissions. In an effort to understand the current state of environmental practice, attitudes, and knowledge among anesthesiologists in the United States, we conducted a survey of American anesthesiologists regarding environmental sustainability. The environmental survey was sent out by e-mail to a random sampling of 5200 members of the American Society of Anesthesiologists. This process was repeated a second time. A total of 2189 anesthesiologists of 5200 responded to the survey, a 42% response rate. Of the survey respondents, 80.1% (confidence interval, 78.2%-81.9%) were interested in recycling. Respondents reported recycling in 27.7% of operating rooms where they work. The majority of respondents (67%; confidence interval, 64%-69%) reported there was insufficient information on how to recycle intraoperatively. Respondents supported sustainability practices such as reprocessing equipment, using prefilled syringes, and donating unused equipment and supplies. The affirmative response rate was 48.4% for reprocessing equipment, 56.6% for using prefilled syringes, and 65.1% for donating equipment and supplies to medical missions. Questions about hospital-wide organization of sustainability programs elicited many "I don't know" responses. Eighteen percent of responders indicated the presence of a sustainability or "green" task force. A total of 12.6% of responders indicated the presence of a mandate from hospital leadership to promote sustainability programs. Two important conclusions drawn from the survey data are a lack of hospital-wide organization of sustainability programs and a belief among survey responders that they lack adequate information on recycling and sustainability.

BACKGROUND: Resection of lesions in eloquent areas of the brain are sometimes best done with the patient awake. An awake patient provides neurological feedback as the lesion is resected. This increases the chances of a complete resection without leaving a patient neurologically devastated. Unfortunately, this procedure is not always well tolerated by the patient. METHODS: We performed a case series of awake craniotomies using a dexmedetomidine infusion. RESULTS: All 17 patients included in our study tolerated the procedure well with no major complications. CONCLUSIONS: The addition of dexmedetomidine to our technique improves safety and comfort for patients undergoing awake craniotomy.
