RESUMO
In March 2020, the New York City metropolitan area became the epicenter of the United States' SARS-CoV-2 pandemic and the surge of new cases threatened to overwhelm the area's hospital systems. This article describes how an anesthesiology department at a large urban academic hospital rapidly adapted and deployed to meet the threat head-on. Topics included are preparatory efforts, development of a team-based staffing model, and a new strategy for resource management. While still maintaining a fully functioning operating theater, discrete teams were deployed to both COVID-19 and non-COVID-19 intensive care units, rapid response/airway management team, the difficult airway response team, and labor and delivery. Additional topics include the creation of a temporary 'pop-up' anesthesiology-run COVID-19 intensive care unit utilizing anesthesia machines for monitoring and ventilatory support as well as the development of a simulation and innovation team that was instrumental in the rapid prototyping of a controlled split-ventilation system and conversion of readily available BIPAP units into emergency ventilators. As the course of the disease is uncertain, the goal of this article is to assist others in preparation for what may come next with COVID-19 as well as potential future pandemics.

INTRODUCTION: To enlarge the donor pool, kidney donors with obesity have been considered. We hypothesized that it is safe for patients with obesity to serve as living kidney donors. METHODS: In this single-center retrospective analysis, we examined the effect of obesity (body mass index (BMI) of 30-35 kg/m2) on glomerular filtration rate (GFR) and creatinine in patients undergoing laparoscopic donor nephrectomy. Other outcomes included intraoperative, 30-, and 90-day complications. We examined the trajectory between patients with obesity versus patients without obesity over time using mixed effects models for the outcomes of creatinine in mg/dL and GFR in mL/min/1.73 m2. RESULTS: Among donors with obesity versus donors without obesity, there were no significant differences in demographics or comorbidities. Baseline creatinine in donors with obesity was significantly greater than that of donors without obesity (p = 0.02). Operative time was significantly longer in donors with obesity versus without obesity (p = 0.03). There was no significant difference in 30-day morbidity between donors with obesity versus without obesity (6.52 vs. 3.57%, respectively; p = 0.38). The rate of graft complications was 8.7% in donors with obesity versus 7.1% in donors without obesity (p = 1.0). 90-day complications were infrequent, and not significant different between the groups. At 6, 12, and 24-month postoperative follow-up, the mean creatinine level in patients with obesity was not significantly different from that of patients without obesity (1.23 vs. 1.31, 1.23 vs. 1.26, and 1.17 vs. 1.19 at 6, 12, and 24 months, respectively). Mean GFR was also not significantly different at 6, 12, and, 24 months. CONCLUSION: Postoperative creatinine and GFR changes were not significantly different in patients with obesity versus without obesity after laparoscopic donor nephrectomy. These findings suggest that carefully screened living kidney donors with obesity do not experience decreased postoperative renal function.

INTRODUCTION: Opioids have played a critical role in the management of perioperative pain following abdominal surgery. Increasing attention is being paid to the deleterious side effects and limitations of this practice. This case report offers a novel alternative to opioid-based analgesia in the form of rectus sheath catheters (RSCs) which we employed as part of an enhanced recovery after surgery (ERAS) protocol. METHODS: Three patients underwent laparoscopic- assisted colorectal surgery and were treated intra- and postoperatively with local anesthesia administered via bilateral rectus sheath catheters as well as by multimodal adjuncts. Evaluations of the patients' pain scores, opioid usage, and abdominal sensitivity to sharp stimuli were conducted daily. RESULTS: The patients demonstrated a substantially lessened opioid requirement over their hospital stay with two of them requiring no opioid analgesic medications postoperatively. DISCUSSION: We suggest that the incorporation of these catheters into an ERAS protocol can play an important role in further reducing perioperative opioid usage for procedures in which pain control can be especially challenging.

OBJECTIVES: The purpose of this study was to evaluate the potential of magnetic resonance (MR) to detect arterial thrombotic obstruction and define thrombus age. BACKGROUND; Arterial thrombi underlie the clinical consequences of atherosclerosis and are not reliably detected by current noninvasive diagnostic techniques. METHODS: Carotid thrombi were induced in swine (n = 7) by arterial injury. Serial high-resolution in vivo MR images were obtained using black-blood T1-weighted (T1W) and T2-weighted (T2W) sequences in a clinical 1.5T MR system at 6 h, 1 day and at 1, 2, 3, 6 and 9 weeks. At each time point one animal was sacrificed and the occluded carotid artery processed for histopathology. Thrombus signal intensity (SI) was normalized to that of the adjacent muscle. Thrombus age was assessed based on MR appearance by two blinded independent observers. RESULTS: Thrombus appearance and relative SI revealed characteristic temporal changes in multicontrast-weighted MR images, reflecting histologic changes in the composition. Acute thrombus appeared very bright on the T2W images, facilitating the detection. Signal intensity was 197 +/- 25% at 6 h, peaking at 1 week (246 +/- 51%), reaching a plateau by 6 weeks (120 +/- 15%). At six weeks, complete thrombus organization was confirmed histologically. The T1W images had similar pattern with lower SI than T2W. Age definition using visual appearance was highly accurate (Pearson's chi-square with 4 df ranging from 96 to 132 and Cohen's kappa at 0.81 to 0.94). Agreement between observers was substantial (Pearson chi-square with 4 df = 91.5, kappa = 0.79). CONCLUSIONS: Magnetic resonance imaging is a promising tool to noninvasively detect arterial thrombosis. Measurement of SI and the characteristic visual appearance of the thrombus have the potential to define thrombus age.

Over the past several decades, there have been evolutionary changes in both surgery and anesthesia. Newer anesthetics have excellent safety profiles and are associated with fewer hemodynamic side effects and rapid elimination from the body. Innovative surgical techniques are less invasive and cause less perioperative patient pain. These developments have fueled the growth of office-based surgery and anesthesia. All types of anesthesia, including local, monitored anesthesia care, general, and regional anesthesia, have been used safely within the private practitioner's office. Because of the remote nature of the private surgeon's office, the proper selection of both patient and procedure to be performed is of utmost importance. It is likewise imperative that the practitioner assures that the patient does not experience excessive postoperative pain and/or nausea and vomiting. It is of the utmost importance that the practicing anesthesiologist assure that every location in which procedures and surgeries are performed is a safe anesthetizing location.
