Inferior Pancreaticoduodenal Artery Aneurysms in Association with Celiac Stenosis/Occlusion

Inferior pancreaticoduodenal artery aneurysms in association with celiac stenosis or occlusion are well described in the literature. These aneurysms are true aneurysms and develop as a result of increased flow through the pancreaticoduodenal arcades in the presence of hemodynamically significant stenosis of the celiac axis or common hepatic artery. Aneurysms may be multiple and rarely associated with aneurysms in other collateral pathways—such as the dorsal pancreatic artery or the arc of Buhler. These aneurysms may be incidentally detected or patients may present with abdominal pain or shock secondary to rupture of the aneurysms. Treatment options include surgical resection and transcatheter embolization; current literature favors the latter option. Treatment of celiac axis stenosis may be recommended in addition to treating the aneurysms; however, no formal guidelines exist on this recommendation

Admissions for isolated nonoperative mild head injuries: Sharing the burden among trauma surgery, neurosurgery, and neurology

Isolated nonoperative mild head injuries (INOMHI) occur with increasing frequency in an aging population. These patients often have multiple social, discharge, and rehabilitation issues, which far exceed the acute component of their care. This study was aimed to compare the outcomes of patients with INOMHI admitted to three services: trauma surgery, neurosurgery, and neurology. Retrospective case series (January 1, 2009 to August 31, 2013) at an academic Level I trauma center. According to an institutional protocol, INOMHI patients with Glasgow Coma Scale (GCS) of 13 to 15 were admitted on a weekly rotational basis to trauma surgery, neurosurgery, and neurology. The three populations were compared, and the primary outcomes were survival rate to discharge, neurological status at hospital discharge as measured by the Glasgow Outcome Score (GOS), and discharge disposition. Four hundred eighty-eight INOMHI patients were admitted (trauma surgery, 172; neurosurgery, 131; neurology, 185). The mean age of the study population was 65.3 years, and 58.8% of patients were male. Seventy-seven percent of patients has a GCS score of 15. Age, sex, mechanism of injury, Charlson Comorbidity Index, Injury Severity Score, Abbreviated Injury Scale in head and neck, and GCS were similar among the three groups. Patients who were admitted to trauma surgery, neurosurgery and neurology services had similar proportions of survivors (98.8% vs 95.7% vs 94.7%), and discharge disposition (home, 57.0% vs 61.6% vs 55.7%). The proportion of patients with GOS of 4 or 5 on discharge was slightly higher among patients admitted to trauma (97.7% vs 93.0% vs 92.4%). In a logistic regression model adjusting for Charlson Comorbidity Index CCI and Abbreviated Injury Scale head and neck scores, patients who were admitted to neurology or neurosurgery had significantly lower odds being discharged with GOS 4 or 5. While the trauma group had the lowest proportion of repeats of brain computed tomography (61.6%), the neurosurgery group had the highest proportion of intensive care unit admission (29.8%), and the neurology group had the longest emergency department stay (7.5 hours), there were no significant differences in duration of hospital stay, in-hospital complications, and readmission within 30 days. Although there were differences in use of health care resources, and the proportion of patients with GOS of 4 or 5 on discharge was slightly higher among patients admitted to trauma, most clinical outcomes were similar in INOMHI patients admitted to trauma surgery, neurosurgery, or neurology in our institution. A rotational policy of admitting INOMHI patients is feasible among services with expertise in and commitment to the care of these patients. Therapeutic/care management study, level IV

The Surgeon as the Second Victim? Results of the Boston Intraoperative Adverse Events Surgeons' Attitude (BISA) Study

An intraoperative adverse event (iAE) is often directly attributable to the surgeon's technical error and/or suboptimal intraoperative judgment. We aimed to examine the psychological impact of iAEs on surgeons as well as the surgeons' attitude about iAE reporting. We conducted a web-based cross-sectional survey of all surgeons at 3 major teaching hospitals of the same university. The 29-item questionnaire was developed using a systematic closed and open approach focused on assessing the surgeons' personal account of iAE incidence, emotional response to iAEs, available support systems, and perspective about the barriers to iAE reporting. The response rate was 44.8% (n = 126). Mean age of respondents was 49 years, 77% were male, and 83% performed >150 procedures/year. During the last year, 32% recalled 1 iAE, 39% recalled 2 to 5 iAEs, and 9% recalled >6 iAEs. The emotional toll of iAEs was significant, with 84% of respondents reporting a combination of anxiety (66%), guilt (60%), sadness (52%), shame/embarrassment (42%), and anger (29%). Colleagues constituted the most helpful support system (42%) rather than friends or family; a few surgeons needed psychological therapy/counseling. As for reporting, 26% preferred not to see their individual iAE rates, and 38% wanted it reported in comparison with their aggregate colleagues' rate. The most common barriers to reporting iAEs were fear of litigation (50%), lack of a standardized reporting system (49%), and absence of a clear iAE definition (48%). Intraoperative AEs occur often, have a significant negative impact on surgeons' well-being, and barriers to transparency are fear of litigation and absence of a well-defined reporting system. Efforts should be made to support surgeons and standardize reporting when iAEs occur

The Association of Age With Short-Term and Long-Term Mortality in Adults Admitted to the Intensive Care Unit

Based on the current literature, it is unclear whether advanced age itself leads to higher mortality in critically ill patients or whether it is due to the greater number of comorbidities in the elderly patients. We hypothesized that increasing age would increase the odds of short-term and long-term mortality after adjusting for baseline comorbidities in intensive care unit (ICU) patients. We performed a retrospective cohort study of 57 160 adults admitted to any ICU over 5 years at 2 academic tertiary care centers. Patients were divided into age-groups, 18 to 39, 40 to 59, 60 to 79, and ≥80. The primary outcomes were 30-day and 365-day mortality. Results were analyzed with multivariate logistic regression adjusting for demographics and the Elixhauser-van Walraven Comorbidity Index. The adjusted 30-day mortality odds ratios (ORs) were 1.39 (95% confidence interval [CI]: 1.21-1.60), 2.00 (95% CI: 1.75-2.28), and 3.33 (95% CI: 2.90-3.82) for age-groups 40 to 59, 60 to 79, and ≥80, respectively, using the age-group 18 to 39 as the reference. The adjusted 365-day mortality ORs were 1.46 (95% CI: 1.32-1.61), 2.10 (95% CI: 1.91-2.31), and 2.96 (95% CI: 2.67-3.27). In critically ill patients, increasing age is associated with higher odds of short-term and long-term death after correcting for existing comorbidities

Mandatory health care insurance is associated with shorter hospital length of stay among critically injured trauma patients

BACKGROUND: The implementation of the Affordable Care Act stimulated interest in outcomes of patients in Massachusetts, a state mandating health insurance as of 2006. We sought to determine the impact of an insurance mandate on hospital use and outcomes among trauma intensive care unit (ICU) patients. METHODS: This is a retrospective cohort study of trauma patients admitted to the ICU conducted at an academic, trauma center. Patients before (2004-2006) and after (2008-2012) the implementation of mandatory health insurance were compared using propensity matching to control for confounders. Outcomes were hospital length of stay (LOS), ICULOS, in-hospital mortality, and discharge disposition. RESULTS: Overall, 1,668 trauma patients were included, with 530 matched on the propensity score in each group. Hospital LOS decreased by a median of 2.0 days, from 9.0 days (interquartile range, 4-15 days; p < 0.01) before to 7.0 days (interquartile range, 4-14) after implementation of the legislation. There were no differences in ICU LOS (3.0 days to 3.0 days, p = 0.44) and mortality (odds ratio [OR], 1.16; 95% confidence interval [CI], 0.83-1.63). Compared with discharges to home, the patients were more likely to be discharged home with home health services after the legislation (OR, 1.70; 95% CI, 1.08-2.68), but there was no significant change in the likelihoods of the patients being discharged to skilled nursing and rehabilitation facilities (OR, 0.97; 95% CI, 0.72-1.31). CONCLUSION: Implementation of health care reform was associated with a decrease in hospital LOS, with an increase in use of home health services and no change in ICU LOS and mortality among trauma ICU patients at our institution.

Differential effects of fresh frozen plasma and normal saline on secondary brain damage in a large animal model of polytrauma, hemorrhage and traumatic brain injury

We have previously shown that the extent of traumatic brain injury (TBI) in large animal models can be reduced with early infusion of fresh frozen plasma (FFP), but the precise mechanisms remain unclear. In this study, we investigated whether resuscitation with FFP or normal saline differed in their effects on cerebral metabolism and excitotoxic secondary brain injury in a model of polytrauma, TBI, and hemorrhagic shock. Yorkshire swine (n = 10) underwent Grade III liver injury, rib fracture, standardized TBI, and volume-controlled hemorrhage, (40% ± 5%) and were randomly resuscitated with either FFP or normal saline. Hemodynamic parameters and brain oxygenation were continuously monitored, while microdialysis was used to measure the brain concentrations of pyruvate, lactate, glutamate, and glycerol at baseline; 1 hour and 2 hours after shock; immediate postresuscitation (PR); as well as 2, 4, and 6 hours PR. Cells from the injured hemisphere were separated into mitochondrial and cytosolic fractions and analyzed for activity of the pyruvate dehydrogenase complex (PDH). There were no baseline differences in cerebral perfusion pressure, brain oxygenation, as well as concentrations of pyruvate, lactate, glutamate, and glycerol between the groups. At 2 hours and 4 hours PR, the FFP group had significantly higher cerebral perfusion pressures (52 [5] mm Hg vs. 43 [2] mm Hg, p = 0.016; and 50 [7] mm Hg vs. 37 [1] mm Hg, p = 0.008, respectively). There was a sustained and significant (p < 0.05) drop in the glutamate and glycerol levels in the FFP group, implying a decrease in excitotoxicity and brain damage, respectively. Mitochondrial PDH activity was significantly higher (2,666.2 [638.2] adjusted volume INT × mm vs. 1,293.4 [88.8] adjusted volume INT × mm, p = 0.008), and cytosolic PDH activity was correspondingly lower (671.4 [209.2] adjusted volume INT × mm vs. 3070.7 [484.3] adjusted volume INT × mm, p < 0.001) in the FFP group, suggesting an attenuation of mitochondrial dysfunction and permeability. In this model of TBI, polytrauma, and hemorrhage, FFP resuscitation confers neuroprotection by improving cerebral perfusion, diminishing glutamate-mediated excitotoxic secondary brain injury and reducing mitochondrial dysfunction
