Effectiveness of deep general anesthesia compared to the standard depth of general anesthesia for acute postoperative pain and patient safety: a systematic review protocol.

OBJECTIVE: The objective of this systematic review is to synthesize the best available evidence related to the effectiveness of deep general anesthesia on acute postoperative pain and patient safety in adult patients. INTRODUCTION: Acute postoperative pain is a common physiological side effect of surgery that should be alleviated as soon as possible to reduce suffering and other detrimental effects. Given the adverse effects related to the use of opioids for pain management, and in the current opioid epidemic, evidence-based clinical practice recommendations are needed to reduce the use of opioids in the treatment of acute postoperative pain. INCLUSION CRITERIA: This review will include studies of adult patients that incorporate the intervention of deep general anesthesia (bispectral index values of 45 or less), compared to the provision of a standard depth of general anesthesia (bispectral index values 45-60). Included studies will report acute postoperative pain (within the first 48 hours after surgery) as a primary outcome variable. Secondary outcomes of interest include opioid consumption and any reported adverse outcomes. METHODS: A three-step search strategy will be used to locate studies published in English from 1992 (advent of electroencephalography index monitoring technology) in Ovid MEDLINE, Embase and CINAHL databases. Two independent reviewers will assess retrieved studies against inclusion criteria, complete critical appraisal for methodological quality and extract data using a standardized tool. Data will be synthesized using statistical meta-analysis, where possible.

Safe injection practices among anesthesia providers: a scoping review protocol.

OBJECTIVE: The objective of this review is to identify and map literature related to safe injection practices among anesthesia providers in developed nations. The mapped literature will be used to determine if there is sufficient literature available to pose specific questions that can be valuably addressed, through a future systematic review, to reduce the prevalence of unsafe injections. INTRODUCTION: A safe injection is one that does not harm the recipient, does not expose the healthcare worker to avoidable risk, and does not result in waste that is a danger to the community. The literature is replete with examples of disease outbreaks connected to unsafe injections via the misuse of syringes, needles and medications. Many such outbreaks involve unsafe injections by anesthesia providers. INCLUSION CRITERIA: This scoping review will consider any research article or policy document, including unpublished reports, that provides information related to safe injection practices by anesthesia providers in developed nations. METHODS: For studies published in English from 2000, the databases to be searched include Ovid MEDLINE, CINAHL and Google Scholar. The search for unpublished literature will include the websites of anesthesia organizations, the Centers for Disease Control and Prevention, and the National Institutes of Health. Results will be screened by two independent reviewers who will use a standardized tool to independently extract data from each included source. The results of the review will be presented as a map of the data extracted in a tabular form and in a narrative descriptive summary.

The effect of phenylephrine on cerebral perfusion when used to treat anesthesia-induced hypotension: a systematic review protocol.
