Purpose Guidelines regarding the prevention, detection, and management of surgical site infections (SSI) have been published previously.1-3 This document is intended to update prior guidelines based ...on the current literature and to provide a concise summary of relevant topics.
After a person has been injured, prehospital administration of plasma in addition to the initiation of standard resuscitation procedures in the prehospital environment may reduce the risk of ...downstream complications from hemorrhage and shock. Data from large clinical trials are lacking to show either the efficacy or the risks associated with plasma transfusion in the prehospital setting.
To determine the efficacy and safety of prehospital administration of thawed plasma in injured patients who are at risk for hemorrhagic shock, we conducted a pragmatic, multicenter, cluster-randomized, phase 3 superiority trial that compared the administration of thawed plasma with standard-care resuscitation during air medical transport. The primary outcome was mortality at 30 days.
A total of 501 patients were evaluated: 230 patients received plasma (plasma group) and 271 received standard-care resuscitation (standard-care group). Mortality at 30 days was significantly lower in the plasma group than in the standard-care group (23.2% vs. 33.0%; difference, -9.8 percentage points; 95% confidence interval, -18.6 to -1.0%; P=0.03). A similar treatment effect was observed across nine prespecified subgroups (heterogeneity chi-square test, 12.21; P=0.79). Kaplan-Meier curves showed an early separation of the two treatment groups that began 3 hours after randomization and persisted until 30 days after randomization (log-rank chi-square test, 5.70; P=0.02). The median prothrombin-time ratio was lower in the plasma group than in the standard-care group (1.2 interquartile range, 1.1 to 1.4 vs. 1.3 interquartile range, 1.1 to 1.6, P<0.001) after the patients' arrival at the trauma center. No significant differences between the two groups were noted with respect to multiorgan failure, acute lung injury-acute respiratory distress syndrome, nosocomial infections, or allergic or transfusion-related reactions.
In injured patients at risk for hemorrhagic shock, the prehospital administration of thawed plasma was safe and resulted in lower 30-day mortality and a lower median prothrombin-time ratio than standard-care resuscitation.

The ABCs of trauma resuscitation begin with the airway evaluation, and effective airway management is imperative in the care of a patient with critical injury. The Eastern Association for the Surgery ...of Trauma Practice Management Guidelines committee aimed to update the guidelines for emergency tracheal intubation (ETI) published in 2002. These guidelines were made to assist clinicians with decisions regarding airway management for patients immediately following traumatic injury. The goals of the work group were to develop evidence-based guidelines to (1) characterize patients in need of ETI and (2) delineate the most appropriate procedure for patients undergoing ETI.
A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed (www.pubmed.gov).
The search retrieved English-language articles published from 2000 to 2012 involving patients who had sustained blunt trauma, penetrating trauma, or heat-related injury and had developed respiratory system insufficiency or required ETI in the immediate period after injury (first 2 hours after injury). Sixty-nine articles were used to construct this set of practice management guidelines.
The data supported the formation of six Level 1 recommendations, four Level 2 recommendations, and two Level 3 recommendations. In summary, the decision to intubate a patient following traumatic injury is based on multiple factors, including the need for oxygenation and ventilation, the extent and mechanism of injury, predicted operative need, or progression of disease. Rapid sequence intubation with direct laryngoscopy continues to be the recommended method for ETI, although the use of airway adjuncts such as blind insertion supraglottic devices and video laryngoscopy may be useful in facilitating successful ETI and may be preferred in certain patient populations. There is no pharmacologic induction agent of choice for ETI; however, succinylcholine is the neuromuscular blockade agent recommended for rapid sequence intubation.
Objective:
The study objective was to evaluate effects of the COVID-19 pandemic on rates of emergency department (ED) acute appendicitis presentation, management strategies, and patient outcomes.
...Summary Background Data:
Acute appendicitis is the most commonly performed emergency surgery in the United States and is unlikely to improve without medical or surgical intervention. Dramatic reductions in ED visits prompted concern that individuals with serious conditions, such as acute appendicitis, were deferring treatment for fear of contracting COVID-19.
Methods:
Patients from 146 hospitals with diagnosed appendicitis and arrival between March 2016 and May 2020 were selected. Electronic medical records data were retrospectively reviewed to retrieve patient data. Daily admissions were averaged from March 2016 through May 2019 and compared with March 2020. April-specific admissions were compared across the 5-year pre-COVID-19 period to April 2020 to identify differences in volume, demographics, disease severity, and outcomes.
Results:
Appendicitis patient admissions in 2020 decreased throughout March into April, with April experiencing the fewest admissions. April 2020 experienced a substantial decrease in patients who presented with appendicitis, dropping 25.4%, from an average of 2030 patients (2016–2019) to 1516 in 2020. An even greater decrease of 33.8% was observed in pediatric patients (age <18). Overall, 77% of the 146 hospitals experienced a reduction in appendicitis admissions. There were no differences between years in percent of patients treated nonoperatively (
P
=
0.493) incidence of shock (
P
=
0.95), mortality (
P
=
0.24), or need for postoperative procedures (
P
=
0.81).
Conclusions:
Acute appendicitis presentations decreased significantly during the COVID-19 pandemic, while overall management and patient outcomes did not differ from previous years. Further research is needed focusing on putative explanations for decreased hospital presentations unrelated to COVID-19 infection and possible implications for surgical management of uncomplicated acute appendicitis.

Pancreatic or peripancreatic tissue necrosis confers substantial morbidity and mortality. New modalities have created a wide variation in approaches and timing of interventions for necrotizing ...pancreatitis. As acute care surgery evolves, its practitioners are increasingly being called upon to manage these complex patients.
A systematic review of the MEDLINE database using PubMed was performed. English language articles regarding pancreatic necrosis from 1980 to 2014 were included. Letters to the editor, case reports, book chapters, and review articles were excluded. Topics of investigation included operative timing, the use of adjuvant therapy and the type of operative repair. Grading of Recommendations, Assessment, Development and Evaluations methodology was applied to question development, outcome prioritization, evidence quality assessments, and recommendation creation.
Eighty-eight studies were included and underwent full review. Increasing the time to surgical intervention had an improved outcome in each of the periods evaluated (72 hours, 12-14 days, 30 days) with a significant improvement in outcomes if surgery was delayed 30 days. The use of percutaneous and endoscopic procedures was shown to postpone surgery and potentially be definitive. The use of minimally invasive surgery for debridement and drainage has been shown to be safe and associated with reduced morbidity and mortality.
Acute Care Surgeons are uniquely trained to care for those with pancreatic necrosis due their training in critical care and complex surgery with ongoing shock. In adult patients with pancreatic necrosis, we recommend that pancreatic necrosectomy be delayed until at least day 12. During the first 30 days of symptoms with infected necrotic collections, we conditionally recommend surgical debridement only if the patients fail to improve after radiologic or endoscopic drainage. Finally, even with documented infected necrosis, we recommend that patients undergo a step-up approach to surgical intervention as the preferred surgical approach.
Systematic review/guideline, level III.
The Surgical Infection Society (SIS) Guidelines for the treatment of complicated skin and soft tissue infections (SSTIs) were published in October 2009 in
The purpose of this project was to provide a ...succinct update on the earlier guidelines based on an additional decade of data.
We reviewed the previous guidelines eliminating bite wounds and diabetic foot infections including their associated references. Relevant articles on the topic of complicated SSTIs from 2008-2020 were reviewed and graded individually. Comparisons were then made between the old and the new graded recommendations with review of the older references by two authors when there was disparity between the grades.
The majority of new studies addressed antimicrobial options and duration of therapy particularly in complicated abscesses. There were fewer updated studies on diagnosis and specific operative interventions. Many of the topics addressed in the original guidelines had no new literature to evaluate.
Most recommendations remain unchanged from the original guidelines with the exception of increased support for adjuvant antimicrobial therapy after drainage of complex abscess and increased data for the use of alternative antimicrobial agents.
Catheter-associated urinary tract infections (CAUTI) are common in surgical patients. CAUTI are associated with adverse patient outcomes, and negatively affects public safety reporting and ...reimbursement. Inappropriate catheter use and prolonged catheter duration are major risk factors for CAUTI. CAUTI pathogenesis and treatment are complicated by the presence of biofilms. Prevention strategies include accurate identification and tracking of CAUTIs, and the development of institutional guidelines for the appropriate use, duration, alternatives, and removal of indwelling urinary catheters.
Abstract Background There has been an increasing emphasis on identifying elderly trauma patients. However, definitions based solely on age vary widely, ranging from age 55 to 80 years, hampering ...optimal trauma management for older patients. The goal of this study was to develop an objective, data-driven definition for “elderly” in trauma care by evaluating mortality risk as a function of age. Methods We conducted a retrospective analysis of 872,861 adult (≥18 years) patients from the National Trauma Data Bank's National Sample Program from 2003 to 2010. The primary outcome was risk-adjusted in-hospital mortality determined using multivariate logistic regression. Contribution of age to mortality was investigated through step-wise regression and percent of R2 attributable to age. We searched for straight-line trends in mortality rate at each age using the spline function of Statistical Analysis Software. Results Statistically significant increases in mortality rate were noted at ages 37, 60, and 78. Age was found to contribute 10% to mortality compared with greater than 80% for Glasgow coma scale and injury severity score combined. Conclusions Our findings suggest using age 60 years as a data-driven definition of “elderly” in trauma.
Background Human polymerized hemoglobin (PolyHeme, Northfield Laboratories) is a universally compatible oxygen carrier developed to treat life-threatening anemia. This multicenter phase III trial was ...the first US study to assess survival of patients resuscitated with a hemoglobin-based oxygen carrier starting at the scene of injury. Study Design Injured patients with a systolic blood pressure ≤ 90 mmHg were randomized to receive field resuscitation with PolyHeme or crystalloid. Study patients continued to receive up to 6 U of PolyHeme during the first 12 hours postinjury before receiving blood. Control patients received blood on arrival in the trauma center. This trial was conducted as a dual superiority/noninferiority primary end point. Results Seven hundred fourteen patients were enrolled at 29 urban Level I trauma centers (79% men; mean age 37.1 years). Injury mechanism was blunt trauma in 48%, and median transport time was 26 minutes. There was no significant difference between day 30 mortality in the as-randomized (13.4% PolyHeme versus 9.6% control) or per-protocol (11.1% PolyHeme versus 9.3% control) cohorts. Allogeneic blood use was lower in the PolyHeme group (68% versus 50% in the first 12 hours). The incidence of multiple organ failure was similar (7.4% PolyHeme versus 5.5% control). Adverse events (93% versus 88%; p = 0.04) and serious adverse events (40% versus 35%; p = 0.12), as anticipated, were frequent in the PolyHeme and control groups, respectively. Although myocardial infarction was reported by the investigators more frequently in the PolyHeme group (3% PolyHeme versus 1% control), a blinded committee of experts reviewed records of all enrolled patients and found no discernable difference between groups. Conclusions Patients resuscitated with PolyHeme, without stored blood for up to 6 U in 12 hours postinjury, had outcomes comparable with those for the standard of care. Although there were more adverse events in the PolyHeme group, the benefit-to-risk ratio of PolyHeme is favorable when blood is needed but not available.
