RESUMO
BACKGROUND: The optimal method of pain control for patients with traumatic rib fractures is unknown. The aim of this study was to determine the effect of epidural analgesia on respiratory complications and in-hospital mortality in patients with rib fractures. METHODS: Adult patients at a level I trauma center with ≥1 rib fracture from blunt trauma were included (2004-2013). Those with a blunt-penetrating mechanism, traumatic brain injury, or underwent a laparotomy or thoracotomy were excluded. Patients who were treated with epidural analgesia (EPI) were compared with those were not treated with epidural analgesia (NEPI) using coarsened exact matching. Primary outcomes were respiratory complications (pneumonia, deep vein thrombosis/pulmonary embolus, and respiratory failure) and 30-d in-hospital mortality. Secondary outcomes were total hospital and intensive care unit length of stay, and duration of ventilator support. RESULTS: About 1360 patients (EPI: 329 and NEPI: 1031) met inclusion criteria (mean age: 54.2 y; standard deviation [SD]: 19.7; 68% male). The mean number of rib fractures was 4.8 (SD: 3.3; 21% bilateral) with a high total burden of injury (mean Injury Severity Score: 19.9 [SD: 8.9]). The overall incidence of respiratory complications was 13% and mortality was 4%. After matching, 204 EPI patients were compared with 204 NEPI patients, with no differences in baseline characteristics. EPI patients experienced more respiratory complications (19% versus 10%, P = 0.009), but no differences in 30-d mortality (5% versus 2%, P = 0.159), duration of mechanical ventilation (EPI: 148 h [SD: 167] versus NEPI: 117 h [SD: 187], P = 0.434), or duration of intensive care unit length of stay (6.5 d [SD: 7.6] versus 5.8 d [SD: 9.1], P = 0.626). Hospital stay was higher in the EPI group (16.6 d [SD: 19.6] vs 12.7 d [SD: 15.2], P = 0.026). CONCLUSIONS: Epidural analgesia is associated with increased respiratory complications without providing mortality benefit after traumatic rib fractures. Alternate analgesic strategies should be investigated to treat these severely injured patients.

BACKGROUND: As the implementation of exclusive acute care surgery (ACS) services thrives, prognostication for mortality and morbidity will be important to complement clinical management of these diverse and complex patients. Our objective is to investigate prognostic risk factors from patient level characteristics and clinical presentation to predict outcomes including mortality, postoperative complications, intensive care unit (ICU) admission and prolonged duration of hospital stay. METHODS: Retrospective review of all emergency general surgery admissions over a 1-year period at a large teaching hospital was conducted. Factors collected included history of present illness, physical exam and laboratory parameters at presentation. Univariate analysis was performed to examine the relationship between each variable and our outcomes with chi-square for categorical variables and the Wilcoxon rank-sum statistic for continuous variables. Multivariate analysis was performed using backward stepwise logistic regression to evaluate for independent predictors. RESULTS: A total of 527 ACS admissions were identified with 8.1% requiring ICU stay and an overall crude mortality rate of 3.04%. Operative management was required in 258 patients with 22% having postoperative complications. Use of anti-coagulants, systolic blood pressure <90, hypothermia and leukopenia were independent predictors of in-hospital mortality. Leukopenia, smoking and tachycardia at presentation were also prognostic for the development of postoperative complications. For ICU admission, use of anti-coagulants, leukopenia, leukocytosis and tachypnea at presentation were all independent predictive factors. A prolonged length of stay was associated with increasing age, higher American Society of Anesthesiologists class, tachycardia and presence of complications on multivariate analysis. CONCLUSIONS: Factors present at initial presentation can be used to predict morbidity and mortality in ACS patients.

OBJECTIVES: Vasopressors are not recommended by current trauma guidelines, but recent reports indicate that they are commonly used. We aimed to describe the early hemodynamic management of trauma patients outside densely populated urban centers. METHODS: We conducted a single-center retrospective cohort study in a Canadian regional trauma center. All adult patients treated for traumatic injury in 2013 who died within 24 hours of admission or were transferred to the intensive care unit were included. A systolic blood pressure <90 mmHg, a mean arterial pressure <60 mmHg, the use of vasopressors or ≥2 L of intravenous fluids defined hemodynamic instability. Main outcome measures were use of intravenous fluids and vasopressors prior to surgical or endovascular management. RESULTS: Of 111 eligible patients, 63 met our criteria for hemodynamic instability. Of these, 60 (95%) had sustained blunt injury and 22 (35%) had concomitant severe traumatic brain injury. The subgroup of patients referred from a primary or secondary hospital (20 of 63, 32%) had significantly longer transport times (243 vs. 61 min, p<0.01). Vasopressors, used in 26 patients (41%), were independently associated with severe traumatic brain injury (odds ratio 10.2, 95% CI 2.7-38.5). CONCLUSIONS: In this cohort, most trauma patients had suffered multiple blunt injuries. Patients were likely to receive vasopressors during the early phase of trauma care, particularly if they exhibited signs of neurologic injury. While these results may be context-specific, determining the risk-benefit trade-offs of fluid resuscitation, vasopressors and permissive hypotension in specific patients subgroups constitutes a priority for trauma research going forwards.

BACKGROUND: We evaluated the role of the Charlson age-comorbidity index (CACI), a weighted comorbidity index that reflects cumulative increased likelihood of 1-year mortality, in predicting perioperative outcomes in an emergency general surgery population at a large Canadian teaching hospital. METHODS: A retrospective chart review of emergency general surgery admissions in 2010 was conducted. Patients who had surgery were identified. Mode of surgery and CACI were recorded, as well as measures of outcome, including 30-day mortality and intensive care unit (ICU) admission. A multivariate stepwise logistic regression model was created to assess the effect of age-adjusted Charlson comorbidity index on postoperative outcomes while controlling for the effect of possible confounders. The prediction ability of CACI for mortality was assessed using receiver operating characteristic analyses considering the area under the curve and its 95% confidence intervals (CIs). RESULTS: Of the 529 admissions to general surgery from the emergency department, 257 patients underwent a surgical intervention. The CACI scores ranged from 0 to 16. We described a total of 11 deaths (4.3%) and 30 ICU admissions (11.7%). CACI was associated with an increased risk of 30-day mortality (adjusted odds ratio,1.39; 95% CI, 1.11-1.73; p = 0.0034). Receiver operating characteristic analysis was consistent with high accuracy of CACI for mortality prediction alone, resulting in area under the curve or c statistic of 0.90 (95% CI, 0.84-0.95). CACI was similar in predicting mortality to a multivariate model. CACI was also found to be associated with ICU admission (adjusted odds ratio, 1.17; 95% CI, 1.01-1.37; p < 0.0382). CACI is not as good a predictor for ICU admission when compared with the multivariate model. CONCLUSION: We have shown that the CACI is a valid tool for 30-day mortality prediction in the context of emergency general surgery. LEVEL OF EVIDENCE: Prognostic study, level III.
