An Update On The Role Of Multimodal Analgesia In Perioperative Pain Management, Whitney N. Kuwamoto, Grace C. Eddy, Edward R. Mariano, Eric S. Schwenk

Department of Anesthesiology Faculty Papers

Multimodal analgesia has become a foundational principle of acute perioperative pain management and enhanced recovery and involves the application of nonpharmacologic, pharmacologic, and/or interventional techniques. The overall goal of this approach is to apply a combination of different modalities that target discrete points along the pain pathway and thereby avoid the overreliance on opioids and associated side effects. Since our review in 2018, there have been significant developments that have prompted an updated review of multimodal analgesia. In this article, we identify and summarize important trends that influence the current approach to acute perioperative pain management as well as provide …

Postoperative Anaemia: The Unseen Challenge In Cardiac Surgery, Matthew A. Warner, Jacob Raphael

Department of Anesthesiology Faculty Papers

Postoperative anaemia is an overlooked complication of cardiac surgery that is associated with adverse clinical outcomes. Although small clinical trials suggest that postoperative treatment with i.v. iron improves haemoglobin recovery and reduces transfusion utilisation, appropriately powered randomised controlled trials are necessary to definitively evaluate the efficacy of treatment on clinical outcomes of importance to patients, clinicians, and healthcare systems. A comprehensive approach to perioperative anaemia management demands a renewed focus on both prevention and treatment to improve patient outcomes.

Perioperative Repercussions Of Cannabis Use-Implications For Gi Endoscopy Sedation, Basavana Goudra, Michael Green

Department of Anesthesiology Faculty Papers

The legalization of cannabis in multiple U.S. states and several other countries, along with its increasing social acceptance across diverse demographic and socioeconomic groups, has led to a growing number of patients presenting for interventional procedures with a history of cannabis use. Although anesthetic and sedation-related implications may be less pronounced than in major surgery, they remain clinically relevant and warrant careful consideration. Key factors include acute intoxication, chronic use, and cannabis use disorder. Cannabis users often require higher-and sometimes unpredictable-doses of propofol and other sedatives. Inhalational use is associated with airway hyperreactivity, increasing the risk of bronchospasm and, in …

A Review Of Gut Failure As A Cause And Consequence Of Critical Illness, Danielle E. Soranno, Craig M. Coopersmith, Jessica F. Brinkworth, Faith N. F. Factora, Julia H. Muntean, Monty G. Mythen, Jacob Raphael, Andrew D. Shaw, Vidula Vachharajani, Jeannette S. Messer

Department of Anesthesiology Faculty Papers

In critical illness, all elements of gut function are perturbed. Dysbiosis develops as the gut microbial community loses taxonomic diversity and new virulence factors appear. Intestinal permeability increases, allowing for translocation of bacteria and/or bacterial products. Epithelial function is altered at a cellular level and homeostasis of the epithelial monolayer is compromised by increased intestinal epithelial cell death and decreased proliferation. Gut immunity is impaired with simultaneous activation of maladaptive pro- and anti-inflammatory signals leading to both tissue damage and susceptibility to infections. Additionally, splanchnic vasoconstriction leads to decreased blood flow with local ischemic changes. Together, these interrelated elements of …

Glucose-Lowering Agents Developed In The Last Two Decades And Their Perioperative Implications, Basavana Goudra, Geno Merli, Michael Green

Department of Anesthesiology Faculty Papers

The last two decades have provided far more options f both patients and their physicians in the treatment of diabetes mellitus. While dipeptidyl peptidase-4 inhibitors (DPP-4is) and glucagon-like peptide 1 receptor agonists (GLP-1RAs) have been approved for nearly two decades, sodium-glucose cotransporter 2 inhibitors (SGLT-2is) are relatively new. Of interest to perioperative physicians, these drugs present specific perioperative concerns, prompting many societies to issue guidelines. Retained gastric contents due to slow gastric emptying is a significant drawback of GLP-1RAs, increasing the risk of aspiration. Recommendations include withholding GLP-1RAs for a predefined period of time, performing gastric ultrasound to evaluate gastric …

A Comprehensive Analysis Of In-Hospital Adverse Events After Scopolamine Administration: Insights From A Retrospective Cohort Study Using A Large Nationwide Inpatient Database, George Sun, Marc Torjman, Kevin Min

Setting Up An Ambulatory Gi Endoscopy Suite In The Usa-Anesthesia And Sedation Challenges, Basavana Goudra

Department of Anesthesiology Faculty Papers

Gastrointestinal endoscopy units, both freestanding and associated with ambulatory surgical centers, are on the increase, and the trend is likely to continue. The concept is relatively new, and there are insufficient guidelines and a general dearth of information for prospective planners and physicians. Debate continues in areas such as the selection of patients, appropriateness of procedures, and access to tertiary care. Leaders often scramble to address both critical and non-critical issues, often after the center has opened to the public. They often encounter issues which were not anticipated. In this review, we have provided comprehensive and concise information on the …

Remimazolam And Its Place In The Current Landscape Of Procedural Sedation And General Anesthesia, Matthew Brohan, Janette Brohan, Basavana Goudra

Department of Anesthesiology Faculty Papers

Remimazolam was derived from its parent compound by adding an ester linkage into its structure so that the drug becomes a substrate for ester metabolism. As a result, it undergoes organ-independent ester hydrolysis, although the clinical benefits in terms of shorter recovery are not uniformly observed in clinical practice. Remimazolam is mainly tested in procedural sedation. In comparison to propofol, the current gold standard for procedural sedation, its proposed attractiveness is shorter wake-up times and a clear-headed recovery. Its clear advantages over propofol are better hemodynamic stability, lack of pain on injection and availability of a reversal agent in the …

Progressive Acceleration Of Insulin Exposure Over 7 Days Of Infusion Set Wear, Jasmin R. Kastner, Timothy S. Bailey, Poul Strange, Leon Shi, Keith A. Oberg, Paul J. Strasma, Jeffrey I. Joseph, Douglas B. Muchmore

Department of Anesthesiology Faculty Papers

Insulin exposure varies over 3 days of insulin infusion set (IIS) wear making day-to-day insulin dosing challenging for people with diabetes (PWD). Here we report insulin pharmacodynamic (PD) and pharmacokinetic (PK) data extending these observations to 7 days of IIS wear. PWD (A1C ≤8.5%, C-peptide tmax (P < 0.001), Cmax (P < 0.05), and mean residence time (P < 0.0001). Area under the insulin concentration curve (AUC0–300) declined by ∼24% from days 0 to 7 (P < 0.05). These results confirm/extend previous observations showing progressive acceleration of insulin exposure over IIS wear time. This may have implications for PWD and designers of closed-loop algorithms, although larger studies are necessary to confirm this. The study was registered in clinicaltrials.gov (NCT04398030).

Department of Anesthesiology Faculty Papers

Fibrodysplasia ossificans progressiva (FOP) is a rare and devastating genetic disease, in which soft connective tissue is converted into heterotopic bone through an endochondral ossification process. Patients succumb early as they gradually become trapped in a second skeleton of heterotopic bone. Although the underlying genetic defect is long known, the inherent complexity of the disease has hindered the discovery of effective preventions and treatments. New developments in the gene therapy field have motivated its consideration as an attractive therapeutic option for FOP. However, the immune system's role in FOP activation and the as-yet unknown primary causative cell, are crucial issues …
