ABSTRACT
BACKGROUND AND OBJECTIVES: Textbook oncologic outcome (TOO) is a benchmark for high-quality surgical cancer care but has not been studied at safety-net hospitals (SNH). The study sought to understand how SNH burden affects TOO achievement in colorectal cancer. METHODS: The National Cancer Database was queried for colorectal cancer patients who underwent resection for stage I-III plus stage IV with liver-only metastases (2010-2019). TOO was defined as R0 resection, AJCC-compliant lymphadenectomy (>12 nodes), no prolonged LOS, no 30-day mortality/readmission, and receipt of stage-appropriate adjuvant chemotherapy. RESULTS: Of 487,195 patients, 66.7% achieved TOO. Lower achievement was explained by adequate lymphadenectomy (87.3%), non-prolonged LOS (76.3%), and receipt of adjuvant chemotherapy in stage III (60.3%) and IV (54.1%). Treatment at high burden hospitals (HBH, >10% Medicaid/uninsured) was a predictor of non-TOO (Stage I/II: OR 0.83, III: OR 0.86, IV: OR 0.83; all p < 0.001). Achieving TOO was associated with decreased mortality (Stage I/II: HR 0.49, III: HR 0.48, IV: HR 0.57; all p < 0.001), and HBH treatment was a predictor of mortality (Stage I/II: HR 1.09, III: HR 1.05, IV: HR 1.07; all p < 0.05). CONCLUSIONS: Treatment at higher SNH burden hospitals was associated with less frequent TOO achievement and increased mortality. Quality improvement targets include receipt of adjuvant chemotherapy and avoidance of prolonged LOS.

BACKGROUND: Minimally invasive surgery has been used for both de novo insertion and salvage of peritoneal dialysis (PD) catheters. Advanced laparoscopic, basic laparoscopic, open, and image-guided techniques have evolved as the most popular techniques. The aim of this guideline was to develop evidence-based guidelines that support surgeons, patients, and other physicians in decisions on minimally invasive peritoneal dialysis access and the salvage of malfunctioning catheters in both adults and children. METHODS: A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons reviewed the literature since the prior guideline was published in 2014 and developed seven key questions in adults and four in children. After a systematic review of the literature, by the panel, evidence-based recommendations were formulated using the Grading of Recommendations Assessment, Development and Evaluation approach. Recommendations for future research were also proposed. RESULTS: After systematic review, data extraction, and evidence to decision meetings, the panel agreed on twelve recommendations for the peri-operative performance of laparoscopic peritoneal dialysis access surgery and management of catheter dysfunction. CONCLUSIONS: In the adult population, conditional recommendations were made in favor of: staged hernia repair followed by PD catheter insertion over simultaneous and traditional start over urgent start of PD when medically possible. Furthermore, the panel suggested advanced laparoscopic insertion techniques rather than basic laparoscopic techniques or open insertion. Conditional recommendations were made for either advanced laparoscopic or image-guided percutaneous insertion and for either nonoperative or operative salvage. A recommendation could not be made regarding concomitant clean-contaminated surgery in adults. In the pediatric population, conditional recommendations were made for either traditional or urgent start of PD, concomitant clean or clean-contaminated surgery and PD catheter placement rather than staged, and advanced laparoscopic placement rather than basic or open insertion.

BACKGROUND: Primary hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) represent the liver's two most common malignant neoplasms. Liver-directed therapies such as ablation have become part of multidisciplinary therapies despite a paucity of data. Therefore, an expert panel was convened to develop evidence-based recommendations regarding the use of microwave ablation (MWA) and radiofrequency ablation (RFA) for HCC or CRLM less than 5 cm in diameter in patients ineligible for other therapies. METHODS: A systematic review was conducted for six key questions (KQ) regarding MWA or RFA for solitary liver tumors in patients deemed poor candidates for first-line therapy. Subject experts used the GRADE methodology to formulate evidence-based recommendations and future research recommendations. RESULTS: The panel addressed six KQs pertaining to MWA vs. RFA outcomes and laparoscopic vs. percutaneous MWA. The available evidence was poor quality and individual studies included both HCC and CRLM. Therefore, the six KQs were condensed into two, recognizing that these were two disparate tumor groups and this grouping was somewhat arbitrary. With this significant limitation, the panel suggested that in appropriately selected patients, either MWA or RFA can be safe and feasible. However, this recommendation must be implemented cautiously when simultaneously considering patients with two disparate tumor biologies. The limited data suggested that laparoscopic MWA of anatomically more difficult tumors has a compensatory higher morbidity profile compared to percutaneous MWA, while achieving similar overall 1-year survival. Thus, either approach can be appropriate depending on patient-specific factors (very low certainty of evidence). CONCLUSION: Given the weak evidence, these guidelines provide modest guidance regarding liver ablative therapies for HCC and CRLM. Liver ablation is just one component of a multimodal approach and its use is currently limited to a highly selected population. The quality of the existing data is very low and therefore limits the strength of the guidelines.

BACKGROUND: The SAGES Guidelines Committee has implemented processes for Quality Assessment of SAGES-endorsed guidelines, with the aim of improving the quality of published guidelines. METHODS: We provide details of the processes developed, using standardized tools for assessing the methodological quality of practice guidelines. As an example, we describe the application of our processes to the recent multi-societal GERD consensus guideline. RESULTS: Assessment of the multi-societal GERD consensus guideline by the iterative processes of SAGES Quality Assurance taskforce improved the quality of the final manuscript in all domains of appraisal. These processes are easily applicable to future guidelines. CONCLUSIONS: Such systems will increase the confidence in SAGES recommendations and increase the implementation of SAGES guidelines. By demonstrating the rigor of Quality Assessment, this confidence also extends to a further increase in the assurance of the publications of the Surgical Endoscopy journal.

BACKGROUND: Primary hepatocellular carcinoma (HCC) and colorectal liver metastases (CRLM) represent the two most common malignant neoplasms of the liver. The objective of this study was to assess outcomes of surgical approaches to liver ablation comparing laparoscopic versus percutaneous microwave ablation (MWA), and MWA versus radiofrequency ablation (RFA) in patients with HCC or CRLM lesions smaller than 5 cm. METHODS: A systematic review was conducted across seven databases, including PubMed, Embase, and Cochrane, to identify all comparative studies between 1937 and 2021. Two independent reviewers screened for eligibility, extracted data for selected studies, and assessed study bias using the modified Newcastle Ottawa Scale. Random effects meta-analyses were subsequently performed on all available comparative data. RESULTS: From 1066 records screened, 11 studies were deemed relevant to the study and warranted inclusion. Eight of the 11 studies were at high or uncertain risk for bias. Our meta-analyses of two studies revealed that laparoscopic MW ablation had significantly higher complication rates compared to a percutaneous approach (risk ratio = 4.66; 95% confidence interval = [1.23, 17.22]), but otherwise similar incomplete ablation rates, local recurrence, and oncologic outcomes. The remaining nine studies demonstrated similar efficacy of MWA and RFA, as measured by incomplete ablation, complication rates, local/regional recurrence, and oncologic outcomes, for both HCC and CRLM lesions less than 5 cm (p > 0.05 for all outcomes). There was no statistical subgroup interaction in the analysis of tumors < 3 cm. CONCLUSION: The available comparative evidence regarding both laparoscopic versus percutaneous MWA and MWA versus RFA is limited, evident by the few studies that suffer from high/uncertain risk of bias. Additional high-quality randomized trials or statistically matched cohort studies with sufficient granularity of patient variables, institutional experience, and physician specialty/training will be useful in informing clinical decision making for the ablative treatment of HCC or CRLM.

In patients with acute rib fractures, regional anesthesia has the potential to reduce suffering, decrease opiate use, lower rates of in-hospital delirium, and improve pulmonary function. While many regional anesthesia techniques are complex and time consuming, two single injection nerve blocks, the serratus anterior plane block and erector spinae plane block, are particularly fast, safe, and simple methods to anesthetize the chest wall. Herein we describe two cases in which the serratus anterior plane block and erector spinae plane block were each used with great success in achieving improved pain control in trauma patients with multiple rib fractures. We believe that any provider who routinely cares for patients with rib fractures (emergency physicians and trauma surgeons alike) can and should learn to use these straightforward nerve blocks.
ABSTRACT
BACKGROUND: Phosphatidylserine (PS) is a key cell membrane phospholipid normally maintained on the inner cell surface but externalizes to the outer surface in response to cellular stress. We hypothesized that PS exposure mediates organ dysfunction in hemorrhagic shock. Our aims were to evaluate PS blockade on (1) pulmonary, (2) renal, and (3) gut function, as well as (4) serum lysophosphatidic acid (LPA), an inflammatory mediator generated by PS externalization, as a possible mechanism mediating organ dysfunction. MATERIALS AND METHODS: Rats were either (1) monitored for 130 min (controls, n = 3), (2) hemorrhaged then resuscitated (hemorrhage only group, n = 3), or (3) treated with Diannexin (DA), a PS blocking agent, followed by hemorrhage and resuscitation (DA + hemorrhage group, n = 4). Pulmonary dysfunction was assessed by arterial partial pressure of oxygen, renal dysfunction by serum creatinine, and gut dysfunction by mesenteric endothelial permeability (LP). LPA levels were measured in all groups. RESULTS: Pulmonary: there was no difference in arterial partial pressure of oxygen between groups. Renal: after resuscitation, creatinine levels were lower after PS blockade with DA versus hemorrhage only group (P = 0.01). Gut: LP was decreased after PS blockade with DA versus hemorrhage only group (P < 0.01). Finally, LPA levels were also lower after PS blockade with DA versus the hemorrhage only group but higher than the control group (P < 0.01). CONCLUSIONS: PS blockade with DA decreased renal and gut dysfunction associated with hemorrhagic shock and attenuated the magnitude of LPA generation. Our findings suggest potential for therapeutic targets in the future that could prevent organ dysfunction associated with hemorrhagic shock.

BACKGROUND: Phosphatidylserine is usually an intracellularly oriented cell membrane phospholipid. Externalized phosphatidylserine on activated cells is a signal for phagocytosis. In sepsis, persistent phosphatidylserine exposure is also a signal for activation of the coagulation and inflammatory cascades. As such, phosphatidylserine may be a key molecule in sepsis induced cellular and organ injury. We hypothesize that phosphatidylserine blockade provides a protective effect in sepsis induced organ dysfunction. METHODS: Sepsis was induced in adult female rats using an endotoxin model. Diannexin, a homodimer of annexin A5, was administered for phosphatidylserine blockade. Rats were allocated to control (n = 5), sepsis (n = 6), or sepsis and phosphatidylserine blockade (n = 9) groups. Gut, pulmonary, renal, and hematologic dysfunctions were evaluated by mesenteric microvascular fluid leak, partial pressure of oxygen, serum creatinine, activated clotting time, and glomerular fibrin deposition, respectively. RESULTS: Rats in the sepsis group demonstrated gut, renal, and hematologic dysfunction. Phosphatidylserine blockade reversed signs of gut dysfunction and mesenteric microvascular leak (P < .01). In addition, phosphatidylserine blockade corrected systemic coagulopathy, as measured by activated clotting time (P = .03) and glomerular fibrin deposition (P = .008). There was no difference in renal dysfunction (P = .1) or pulmonary dysfunction in any of the groups (P = .6). CONCLUSION: In sepsis, phosphatidylserine blockade had a protective effect on gut dysfunction and coagulopathy. Increased phosphatidylserine exposure may be a key mediator of organ dysfunction and coagulopathy during sepsis. These data may provide insights into novel treatment options for septic patients.

The ultrasound-guided transversus abdominis plane (TAP) block or TAP block is a well-established regional anesthetic block used by anesthesiologists for peri-operative pain control of the anterior abdominal wall. Multiple studies have demonstrated its utility to control pain for a range of procedures from inguinal hernia repair, laparoscopic cholecystectomies to cesarean sections [1-3]. There are no cases describing the efficacy of the ultrasound-guided TAP block in the emergency department as a part of a multimodal pain pathway for patients diagnosed with acute appendicitis. We developed a pain protocol in conjunction with our surgical colleagues that incorporates the TAP block to reduce opioid use, and better treat acute pain in patients with acute appendicitis diagnosed in the emergency department. We successfully performed ultrasound-guided TAP blocks in 3 patients with computed tomography confirmed appendicitis, reducing pain and need for further opioid use. This interdepartmental collaborative pathway could be an ideal anesthetic plan for patients diagnosed in the emergency department with acute appendicitis.

Treatment of Crohn's disease (CD) relies on medical therapy with surgery reserved for medically refractory cases. This study measured pharmaceutical therapies that CD patients receive before surgery. Prospective data were collected on 558 patients undergoing surgery for medically refractory CD from November 1999 through June 2014. Patient demographics and preoperative medical therapies were tabulated, including types and number of doses of aminosalicylic acid, corticosteroids, immunomodulators, and biologic therapies. Most patients had been treated with preoperative aminosalicylic acid (72%), steroids (77%), or immunomodulators (69%). Forty-two per cent of patients were treated with a biologic before surgery with a mean number of 20 doses (range, 1-130). In 29 per cent of patients, all therapeutic modalities were used before surgery. Biologic therapy was more common in the last seven years of the study compared with the first eight years (64% vs 35%; P < 0.01). More patients had been treated with all therapeutic modalities before surgery in the second half of the study period (37% vs 19%; P < 0.01). CD patients undergoing surgery have had extensive pharmaceutical treatment. In the current era, more patients have been placed on biologic therapies and more than one third of them failed all available classes of medications before surgical intervention.

OBJECTIVE: To identify the optimal timing of perioperative chemical thromboprophylaxis (CTP) and incidence of occult preoperative deep vein thrombosis (OP-DVT) in patients undergoing major colorectal surgery. BACKGROUND: There is limited Level 1 data regarding the optimal timing of CTP in major colorectal surgery and the incidence of OP-DVT remains unclear. Both issues influence the occurrence of venous thromboembolism (VTE) and may impact Medicare reimbursement because of penalties for hospital-acquired conditions. METHODS: Patients undergoing major colorectal surgery underwent preoperative lower extremity venous duplex (LEVD) immediately before surgery. Those without OP-DVT were randomized to preoperative or postoperative CTP with 5000 units of subcutaneous heparin. Patients underwent repeat LEVD in the recovery room and on postoperative day 2. Outcome measures included early (48-hrs) and overall (30-days) postoperative VTE, bleeding complications, and OP-DVT. RESULTS: Eighteen patients (4.2%) had OP-DVT and were excluded. The randomized group included 376 patients (51.6% female) with mean age of 52.7â±â17.6 years. No pulmonary embolism occurred. There was no significant difference in preoperative versus postoperative CTP with respect to early postoperative DVT [3/184 (1.6%) vs 5/192 (2.6%); P = 0.72], DVT at 30 days (1.6% vs 3.6%; P = 0.34) or bleeding complications requiring reoperation (0.5% vs 1.6%; P = 0.62). CONCLUSIONS: The risk of OP-DVT is higher than that of perioperative DVT after colorectal surgery and preoperative screening LEVD should be considered to identify and treat patients at risk for pulmonary embolism. Preoperative and postoperative CTP are equally safe in protecting against VTE. CMS should account for these factors when assigning financial disincentives for perioperative VTE.

BACKGROUND: Trauma patients at risk of deterioration because of occult injury may be hemodynamically normal on arrival. Early identification of these patients may improve care, especially for those who require massive transfusion (MT). We hypothesized that elevated admission lactate would predict the need for MT in hemodynamically normal patients. MATERIALS AND METHODS: All trauma patients treated at our university-based urban center over a 5-year period were reviewed. We included hemodynamically normal patients who had an admission lactate performed. First, a receiver-operating curve was used to determine the threshold lactate value. Subsequent analyses were then based on this value. Variables were analyzed using chi-square and unpaired t-tests, and univariable and multivariable regressions. RESULTS: There were 3468 hemodynamically normal patients with an admission lactate. Those who received MT (n = 19) had higher lactate than those who did not (n = 3449; 5.6 versus 2.6 mmol/L, P ≤ 0.001). Receiver-operating curve curve analysis revealed a threshold lactate value of 4 mmol/L with an area under the curve of 0.71. Patients with a lactate of >4 mmol/L had increased mortality (8% versus 2%), longer hospital length of stay (LOS, 6 versus 3 days), longer intensive care unit (ICU) LOS (6 versus 3 days), greater need for MT (2.8% versus 0.3%), and greater blood requirement (219 versus 38 mL; all P values < 0.001). After controlling for confounding variables, the predictive value of admission lactate >4 remained strong (odds ratio, 5.2; 95% confidence interval, 1.87-14.2). CONCLUSIONS: In hemodynamically normal trauma patients, the admission lactate of >4 mmol/L is a robust predictor of MT requirement and associated with poor outcomes.

INTRODUCTION: Treatment of traumatic vascular injury is evolving because of endovascular therapies. National guidelines advocate for embolization of injuries to lower extremity branch vessels, including pseudoaneurysms or arteriovenous fistulas, in hemodynamically normal patients without hard signs of vascular injury. However, patient stability and injury type may limit endovascular applicability at some centers. We hypothesized that for penetrating trauma, indications for endovascular treatment of peripheral vascular injuries, as outlined by national guidelines, are infrequent. METHODS: We reviewed records of patients sustaining penetrating peripheral vascular injuries treated at our university-based urban trauma center from 2006-2010. Patient demographics and outcomes were analyzed. RESULTS: In 92 patients with penetrating peripheral vascular injuries, 82 were managed operatively and 10 were managed nonoperatively. Seventeen (18%) were hemodynamically unstable on arrival, 44 (48%) had multiple vessels injured, and 76 (83%) presented at night and/or on the weekend. No pseudoaneurysms or arteriovenous fistulas were seen initially or at follow-up. Applying national guidelines to our cohort, only two patients (2.2%) met recommended criteria for endovascular treatment. CONCLUSIONS: According to national guidelines, indications for endovascular treatment of penetrating peripheral vascular injury are infrequent. Nearly two-thirds of patients with penetrating peripheral vascular injuries were hemodynamically unstable or had multiple vessels injured, making endovascular repair less desirable. Additionally, over 80% presented at night and/or on the weekend, which could delay treatment at some centers due to mobilization of the endovascular team. Trauma centers need to consider their resources when incorporating national guidelines in their treatment algorithms of penetrating vascular trauma.

In trauma patients with a suspicion for traumatic brain injury (TBI), a head computed tomography (CT) scan is imperative. However, uncooperative patients often cannot undergo imaging without sedation and may need to be intubated. Our hypothesis was that among mildly injured trauma patients, in whom there is a suspicion of a head injury, uncooperative patients have higher rates of TBI and intubation should be considered to obtain a CT scan. We found that uncooperative patients intubated for diagnostic purposes were more likely to have moderate to severe TBI than nonintubated patients (21.4 vs. 8.4%, P < 0.0001) and uncooperative behavior leading to intubation was an independent predictor of TBI (odds ratio, 2.5; 95% confidence interval, 1.5 to 4.5). Of patients with brain injury, intubated patients more often had a head abbreviated injury scale score of 4 (20.8 vs. 7.9%, P = 0.04). Uncooperative intubated patients had longer hospital stays (3.6 vs. 2.6 days, P = 0.003) and higher mortality (0.9 vs. 0.2%, P = 0.02) than nonintubated patients. Uncooperative behavior may be an early warning sign of TBI and the trauma surgeon should consider intubating uncooperative trauma patients if there is suspicion for brain injury based on the mechanism of their trauma.

INTRODUCTION: The ability of surgery residents to provide continuity of care has come under scrutiny with work hour restrictions. The impact of the surgery resident sign-out period (6-8am and 6-8pm) on trauma outcomes remains unknown. We hypothesize that during shift change, resuscitation times are prolonged with worse outcomes. METHODS: Records of patients treated at a university-based urban trauma center during 2008 and 2009 were reviewed. Patients were separated into a shift change group (6-8am and 6-8pm) and a control group of all other time periods and compared using ANOVA, chi square, and unpaired t-tests. RESULTS: We reviewed the charts of 4361 consecutive trauma patients. There was no difference in gender, acuity, resuscitation times, Glasgow Coma Scale, revised trauma score, injury severity score (ISS), or probability of survival score between patients arriving during shift change compared to other times (p>0.2). There was no difference in total emergency department time for patients arriving during shift change (p = 0.07), even when stratified by ISS (ISS<15, p = 0.09; ISS>15, p = 0.2). Length of stay was increased for patients arriving during shift change compared to other times (5 vs 4 days, p<0.05). This was more pronounced for those with ISS>15 (16 vs 11 days, p = 0.03); however, there was no impact on intensive care unit length of stay, ventilator days, and mortality (p>0.3) regardless of ISS. CONCLUSIONS: Trauma outcomes are generally unaffected by patient arrival during shift change when resident sign-outs occur. Although adaptations are being made to accommodate trauma patient arrival during these times, we need to continue paying close attention, especially to seriously injured patients, to ensure that there are no delays in care that may potentially affect patient outcomes.

Although renal trauma is increasingly managed nonoperatively, severe renovascular injuries occasionally require nephrectomy. Long-term outcomes after trauma nephrectomy are unknown. We hypothesized that the risk of end-stage renal disease (ESRD) is minimal after trauma nephrectomy. We conducted a retrospective review of the following: 1) our university-based, urban trauma center database; 2) the National Trauma Data Bank (NTDB); 3) the National Inpatient Sample (NIS); and 4) the U.S. Renal Data System (USRDS). Data were compiled to estimate the risk of ESRD after trauma nephrectomy in the United States. Of the 232 patients who sustained traumatic renal injuries at our institution from 1998 to 2007, 36 (16%) underwent a nephrectomy an average of approximately four nephrectomies per year. The NTDB reported 1780 trauma nephrectomies from 2002 to 2006, an average of 356 per year. The 2005 NIS data estimated that in the United States, over 20,000 nephrectomies are performed annually for renal cell carcinoma. The USRDS annual incidence of ESRD requiring hemodialysis is over 90,000, of which 0.1 per cent (100 per year) of renal failure is the result of traumatic or surgical loss of a kidney. Considering the large number of nephrectomies performed for cancer, we estimated the risk of trauma nephrectomy causing renal failure that requires dialysis to be 0.5 per cent. National data regarding the etiology of renal failure among patients with ESRD reveal a very low incidence of trauma nephrectomy (0.5%) as a cause; therefore, nephrectomy for trauma can be performed with little concern for long-term dialysis dependence.

There are a growing number of new anticoagulants used as an alternative to warfarin. Surgeons will be confronted with an increasing number of patients who may be on these outpatient medications and must be familiar with their management strategies. The purpose of this review is to examine the mechanisms, monitoring and therapeutic reversal of the non-warfarin antithrombotic agents now so frequently confronting the acute care surgeon.

BACKGROUND: Thoracic ultrasonography is more sensitive than chest radiography (CXR) in detecting pneumothorax; however, the role of ultrasonography to determine resolution of pneumothorax after thoracostomy tube placement for traumatic injury remains unclear. We hypothesized that ultrasonography can be used to determine pneumothorax resolution and facilitate efficient thoracostomy tube removal. We sought to compare the ability of thoracic ultrasonography at the second through fifth intercostal space (ICS) to detect pneumothorax with that of CXR and determine which ICS maximizes the positive and negative predictive value of thoracic ultrasonography for detecting clinically relevant pneumothorax resolution. METHODS: A prospective, blinded clinical study of trauma patients requiring tube thoracostomy placement was performed at a university-based urban trauma center. A surgeon performed daily thoracic ultrasonographies consisting of midclavicular lung evaluation for pleural sliding in ICS 2 through 5. Ultrasonography findings were compared with findings on concurrently obtained portable CXR. RESULTS: Of the patients, 33 underwent 119 ultrasonographies, 109 of which had concomitant portable CXR results for comparison. Ultrasonography of ICS 4 or 5 was better than ICS 2 and 3 at detecting a pneumothorax, with a positive predictive value of 100% and a negative predictive value of 92%. The positive and negative predictive values for ICS 2 were 46% and 93% and for ICS 3 were 63% and 92%, respectively. CONCLUSION: Bedside, surgeon-performed, thoracic ultrasonography of ICS 4 for pneumothorax can safely and efficiently determine clinical resolution of traumatic pneumothorax and aid in the timely removal of thoracostomy tubes. LEVEL OF EVIDENCE: Diagnostic study, level II.

BACKGROUND: Trauma patients may have full stomachs or impaired airway reflexes that place them at risk for aspiration and pneumonia. Our hypothesis was that trauma patients with larger gastric volumes as measured by abdominal computed tomography (CT) at admission have higher rates of pneumonia and worse outcomes. METHODS: We matched an initial cohort of 81 trauma patients with an admission CT of the abdomen and a diagnosis of pneumonia by Injury Severity Score and Abbreviated Injury Score of the head and chest with a control group of 81 trauma patients without pneumonia. We estimated gastric volumes on CT and compared variables using chi-square, t-tests, receiver operating curve analysis, and regression analysis. RESULTS: Patients with pneumonia had larger gastric volumes than those without pneumonia (879 cm(3)versus 704 cm(3); P = 0.04). Receiver operating curve analysis gave a gastric volume threshold value of 700 cm(3) as a predictor of pneumonia. Patients with a gastric volume ≥ 700 cm(3) had more pneumonia (61% versus 41%; P = 0.01), stayed longer in the hospital (27.6 versus 19.7 d; P < 0.05) and the intensive care unit (18.4 versus 12.5 d; P = 0.01), required more days on the ventilator (18.1 versus 12.0 d; P = 0.02), and had a trend toward increased mortality (17% versus 11%; P = 0.2). On multivariate analysis, nasogastric or orogastric tube (odds ratio 3.0; P = 0.004) and gastric volume >700 cm(3) (odds ratio 2.7; P = 0.004) were independent predictors of pneumonia. CONCLUSIONS: Trauma patients who developed pneumonia had larger initial gastric volumes. A straightforward estimate of gastric volume on admission abdominal CT may predict patients at risk for developing pneumonia and poor outcomes. Clinicians should be especially vigilant in taking precautions against pneumonia and have a lower threshold for suspecting pneumonia in patients with abdominal CT gastric volumes ≥ 700 cm(3).

BACKGROUND: The clinical utility of determining cardiac motion on ultrasound has been reported for patients presenting in pulseless medical cardiac arrest. However, the relationship between ultrasound-documented cardiac activity and the probability of surviving pulseless electrical activity has not been examined in populations with trauma. We hypothesized that cardiac activity on ultrasound predicts survival for patients presenting in pulseless traumatic arrest. METHODS: We conducted a retrospective analysis at our university-based urban trauma center of adult patients with trauma, who were pulseless on hospital arrival. Results of cardiac ultrasound performed during trauma resuscitations were compared with the electrocardiogram (EKG) rhythm and survival. RESULTS: Among 318 pulseless patients with trauma, 162 had both EKG tracings and a cardiac ultrasound, and 4.3% of these 162 patients survived to hospital admission. Survival was higher for those with cardiac motion than for those without it (23.5% vs. 1.9% for patients with EKG electrical activity, p = 0.002, and 66.7% vs. 0% for patients without EKG electrical activity, p < 0.001). The sensitivity of ultrasound cardiac motion to predict survival to hospital admission was 86% (specificity, 91%; positive predictive value, 30%; negative predictive value, 99%). When examined by mechanism, sensitivity was 100% for the 111 patients with penetrating trauma and 75% for the 50 patients with blunt trauma. CONCLUSION: Survival in pulseless traumatic arrest is very low, but survival for patients with no cardiac motion on ultrasound is also exceedingly rare. Cardiac ultrasound had a negative predictive value approaching 100% for survival to hospital admission. For patients with prolonged prehospital cardiopulmonary resuscitation, ultrasound evaluation of cardiac motion in pulseless patients with trauma may be a rapid way to help determine which patients have no chance of survival in the setting of lethal injuries, so that futile resuscitations can be stopped.
