Blueprint for the development of resuscitation and emergency critical care fellowships.

The volume of critically ill patients presenting to the emergency department (ED) is increasing rapidly. Continued growth will likely further stress an already strained U.S. health care system. Numerous studies have demonstrated an association with worsened outcomes for critically ill patients boarding in the ED. To address the increasing volume and complexity of critically ill patients presenting to EDs nationwide, resuscitation and emergency critical care (RECC) fellowships were developed. RECC programs teach a general approach to the management of the undifferentiated critically ill patient, advanced management of critically ill patients by disease presentation, and ongoing supportive care of the critically ill patient boarding in the ED. The result is critical care training beyond that of a typical emergency medicine (EM) residency with a focus on the unique features and challenges of caring for critically ill patients in the ED not normally found in critical care fellowships. Graduates from RECC fellowships are well suited to practicing in any ED practice model and may be especially well prepared for EDs that distinguish acuity between zones (e.g., resuscitative care units, ED-based intensive care units). In addition to further developing clinical acumen, RECC fellowships provide graduates with a niche in EM education, research, and administration. In this article, we describe the philosophical principles and practical components necessary for the creation of future RECC fellowships.

The Single-Syringe Versus the Double-Syringe Techniques of Adenosine Administration for Supraventricular Tachycardia: A Systematic Review and Meta-Analysis.

INTRODUCTION: The intravenous double-syringe technique (DST) of adenosine administration is the first-line treatment for stable supraventricular tachycardia (SVT). Alternatively, the single-syringe technique (SST) was recently found to be potentially beneficial in several studies. This study aimed to perform a meta-analysis of the SST versus the DST of adenosine administration for the treatment of SVT. METHODS: We assessed EMBASE, PubMed, Cochrane, and ClinicalTrials.gov databases for randomized controlled trials (RCTs) and non-randomized studies of intervention (NRSIs) comparing the DST to the SST of adenosine administration in patients with SVT. Outcomes included termination rate, termination rate at first dose, total administered dose, adverse effects, and discharge rate. RESULTS: We included four studies (three RCTs and one NRSI) with a total of 178 patients, of whom 99 underwent the SST of adenosine administration. No significant difference was found between treatment groups regarding termination rate, termination rate restricted to RCTs, total administered dose, and discharge rate. Termination rate at first dose (odds ratio 2.87; confidence interval 1.11-7.41; p = 0.03; I2 = 0%) was significantly increased in patients who received the SST. Major adverse effects were observed in only one study. CONCLUSIONS: The SST is probably as safe as the DST and at least as effective for SVT termination, SVT termination at first dose, and discharge rate from the emergency department. However, definitive superiority of one technique is not feasible given the limited sample size. REGISTRATION: PROSPERO identifier nº CRD42022345125.

COVID-19-associated acute disseminated encephalomyelitis (ADEM).

A 51-year-old woman with COVID-19 infection developed coma and an impaired oculocephalic response to one side. MRI of the brain demonstrated acute multifocal demyelinating lesions, and CSF testing did not identify a direct cerebral infection. High-dose steroids followed by a course of IVIG was administered, and the patient regained consciousness over the course of several weeks. As more patients reach the weeks after initial infection with COVID-19, acute disseminated encephalomyelitis should be considered a potentially treatable cause of profound encephalopathy or multifocal neurological deficits.

The emergency medicine approach to the evaluation and treatment of pulmonary embolism.

Each year in the United States, up to 900,000 individuals will suffer from acute pulmonary embolism, resulting in an estimated 200,000 to 300,000 hospital admissions. Despite decades of research on the topic, the diagnosis remains elusive in many situations and the fatality rate remains significant. This issue presents a review of the current evidence guiding the emergency medicine approach to the diagnosis and treatment of pulmonary embolism. Key to this approach is the concept of risk stratification: using factors from the history and physical examination, plus ancillary tests, to guide clinical decision making. The pathophysiology of pulmonary embolism and decision-support tools are reviewed, and emergency department management strategies are described.

Vascular constraints in laparoscopic renal allograft: comparative analysis of multiple and single renal arteries in 976 laparoscopic donor nephrectomies.

BACKGROUND: Since the initial description of laparoscopic donor nephrectomy (LDN) in 1995, the field of renal transplantation has continued to evolve. Although the identification of donor kidneys with multiple renal arteries (MRA) was considered a contraindication to LDN, improvement in the surgical technique to surmount the technical challenges of LDN with MRA have been established as the skill and laparoscopic experience of transplant surgeons evolves with time. Consensus regarding LDN with MRA and recipient outcomes is not uniformly documented amongst the transplant community. METHODS: A retrospective analysis of 976 patients who underwent LDN at our institution from January 1999 to August 2009 was performed. Patients were grouped based on the number of arteries and the data were compared with respect to patient demographics, operative characteristics, postoperative course and complications. RESULTS: The two donor groups had comparable outcomes except for operative time, which was significantly prolonged in patients with MRA kidneys when compared to a single renal artery (SRA) kidney (P < 0.01). 1-, 3-year and estimated overall graft survival for the MRA recipient kidneys was significantly inferior when compared to SRA recipient kidneys. CONCLUSIONS: Our decade long experience with LDN demonstrates that operative times for MRA kidneys are longer than for SRA kidneys, however complication rates are similar. Laparoscopic donor nephrectomy with MRA is a safe and effective procedure for living kidney donation; however, the recipient graft outcomes with MRA kidneys warrant appropriate preoperative counseling of recipients.

Complex pancreatic surgery: safety and feasibility in the community setting.

INTRODUCTION: Advances in technology, innovative surgical procedures, and enhanced perioperative care have allowed more patients to be considered for complex pancreatic surgery. Published reports on the outcomes of pancreatic surgery performed at high volume tertiary referral centers have yielded excellent results. However, similar outcome and safety data from community hospitals is limited. MATERIAL AND METHODS: Consecutive complex pancreatic surgery performed by a single surgeon from December 2004 to December 2009 formed the study group. Factors analyzed included patient demographics, operative procedure, operative time, length of hospital stay, pathology, and 30-day morbidity and mortality. RESULTS: One hundred and nine consecutive patients underwent pancreatic surgery, with a mean patient age of 62.4±15.2 years. Eighty-three patients (76.1%) underwent definitive surgical procedure and 26 patients (23.9%) had palliative bypass after failed palliative biliary stenting. The mean operative time was 229±109 min, the mean length of stay was 8.6±6.5 days and 24 (22.0%) patients had surgical complications. CONCLUSION: Complex pancreatic surgery can be performed safely at high-volume tertiary community hospitals with excellent outcomes comparable to tertiary academic centers. In the ongoing debate about the need for mandatory referral of complex surgical procedures, tertiary community hospitals with well-determined outcomes should be included.

Robotic-assisted laparoscopic donor nephrectomies: early experience and review of the literature.

With over 80,000 patients in the United States awaiting kidney transplantation, renal transplant surgery continues to evolve with attractive surgical options for living donation, which include laparoscopic donor nephrectomy (LDN) and robotic-assisted laparoscopic donor nephrectomy (RALDN). LDN is currently accepted as the gold standard procedure for living donor nephrectomy; RALDN is an evolving technique and may emerge as a preferred procedure over time. We present our initial experience with RALDN from December 2007 to August 2008. Thirty-five patients who underwent RALND were retrospectively analyzed and compared with 35 age- and time (year)-matched patients who underwent LDN. The parameters analyzed were length of hospital stay (3.2 ± 0.9 days, P < 0.59), estimated blood loss (146 ± 363 ml, P < 0.36), operating time (149 ± 44 min, P < 0.23), cold ischemic time (135 ± 202 min, P < 0.19), preoperative creatinine (0.82 ± 0.26 mg/dl, P < 0.46) and postoperative creatinine (1.44 ± 1.03 mg/dl, P < 0.20). There was no statistical difference between RALDN patients with single renal artery (n = 27) and those with more than one renal artery (n = 8) kidneys. There was one serious complication requiring conversion to open laparotomy to control a bleeding renal artery stump following extraction of the kidney. One-year graft survival for the 35 recipients of RALDN was 97.1%. RALDN is feasible and compares favorably to the standard LDN procedure with good graft survival. Robotic-assisted transplant surgery is an emerging technique with potential benefits to both surgeon and patient.

Right Ventricular Pneumocardia Secondary to Hepatic Abscesses.

Gas-filled abscesses and gas gangrenes are extremely rare causes of intrahepatic gas. Even rarer, however, is the occurrence of gas within the non-portal hepatic veins. Most often seen in diabetic patients, dissemination and hepatic seeding of bacteria has been linked to procedures such as femoral catheters as well as liver lacerations and pyelonephritis. We report the case of a 69-year-old relatively healthy male who presented to our emergency department with abdominal pain and a fever of 103.3°F (39.6°C). A contrast-enhanced computed tomography scan of the abdomen revealed multiple hepatic abscesses and gas within the hepatic venous system as well as pneumocardia. In conclusion, gas within the non-portal hepatic veins is usually an indication of a serious underlying condition and its immediate identification is essential for treatment as hematogenous dissemination has already begun.

Nicotine increases alcohol self-administration in non-dependent male smokers.

BACKGROUND: Alcohol and tobacco are commonly co-administered, yet little is known about the effects of acute nicotine administration on alcohol consumption in humans. This study sought to determine how nicotine delivered by tobacco smoke influences alcohol intake in humans using a double-blind placebo controlled repeated measures design. METHODS: During two randomized 120 min sessions 15 male occasional smokers smoked four nicotine-containing or four de-nicotinized cigarettes at 30 min intervals. Throughout the session, subjects could earn units of their preferred alcoholic beverage and glasses of water using a progressive-ratio (PR) task. RESULTS: Wilcoxon signed-rank tests indicated that nicotine increased alcohol self-administration in a significant proportion of participants (Por=0.16). A two-way ANOVA supported this observation further, and, compared to de-nicotinized cigarettes, the nicotine-containing cigarettes increased PR breakpoints for alcohol but not water, as reflected by a Cigarettex Beverage interaction (P
