Tension pneumothorax is commonly treated with needle decompression (ND) at the 2nd intercostal space midclavicular line (2nd ICS MCL) but is thought to have a high failure rate. Few studies have attempted to directly measure the failure rate in patients receiving the intervention. We performed a retrospective analysis of 10 years of patients receiving prehospital ND. CT scans were reviewed to record the location of catheters left indwelling and the proportion of patients who did not have any pneumothorax. Chest wall thickness was measured on both injured and uninjured sides at the 2nd ICS MCL and compared with the recommended alternative, the 5th ICS anterior axillary line (5th ICS AAL). We identified 335 patients that underwent prehospital ND who had CT scans performed. Using our two different radiologic methods of assessing failure, 39 per cent and 76 per cent of attempts at ND failed to reach the pleural space. In addition, at least 39 per cent of patients did not have a tension pneumothorax. Injured chest walls were significantly thicker than uninjured chest walls at both the 2nd ICS MCL and the 5th ICS AAL (both P < 0.005.) Increasing chest wall thickness correlated with the failure of the catheter to reach the pleural space. Using an 8-cm catheter at the 5th ICS AAL, iatrogenic cardiac injury was at risk in 42 per cent of patients. This series confirms the high failure rate of ND at the 2nd ICS MCL, but further studies are needed to assure the safety of using larger catheters at the 5th ICS AAL.

Background It is unknown whether replacing clinic follow-up visits with telephone follow-up for low-risk core emergency general surgery (cEGS) procedures is safe. We measured the efficacy of telephone follow-up to determine if it could safely reduce the need for routine postoperative clinic visits in this population. Study Design Low-risk nonelective laparoscopic appendectomy, laparoscopic cholecystectomy, umbilical hernia, and inguinal hernia repair patients received telephone follow-up for symptoms concerning for surgical complication within 10 days of discharge. Clinic appointments were made if critical thresholds were reached. Outcomes of interest included rates of completed telephone screens, clinic visits avoided, and missed complications at 30 days postoperatively. Results Of 402 patients screened, 62 (15.4%) were scheduled for a clinic visit due to threshold responses and 27 (6.7%) were scheduled per patient request, while 275 (68.4%) patients screened negative and did not attend a clinic visit. One hundred sixty-three (59.3%) of the negative screen cohort were contacted after 30 days. Nine (5.5%) patients in this cohort were diagnosed with low-grade complications; no high-grade (Clavien-Dindo ≥ 3) complications were missed by telephone screening. Twenty surgery-related complications were identified in the full patient population; early telephone screening successfully identified the single high-grade complication. Conclusions Post-discharge telephone follow-up in cEGS patients reduced the need for clinic follow-up visits by 68%. Missed complications were infrequent and low grade; telephone screening identified the single high-grade complication. Telephone follow-up for low-risk EGS patients is safe and increases efficiency of postoperative resource use.

Background: Transversus abdominis plane block (TAP) with liposomal bupivacaine has been studied as an effective method of reducing the need for post-operative opioids and increasing same day discharge rates. However, less is known about the cost-effectiveness of this strategy relative to opioids alone for hernia repair. We performed an economic evaluation of these strategies using a computer simulation model. Methods: A decision tree was constructed to determine cost effectiveness as measured by incremental cost effectiveness ratios (ICER) per quality adjusted life year (QALY). Base case costs, QALY values, and probabilities were derived from published studies and Medicare fee schedules. For input parameters for which we could not find values in the published literature, we used expert opinion. A 1-month time horizon was selected to focus on the immediate post-operative period. Finally, we performed one-way, two-way, and probabilistic sensitivity analyses. Results: The liposomal bupivacaine TAP block was a dominant strategy yielding a $456.75 decrease in cost and an 0.1 increase in QALYs relative to opioids alone. In one-way sensitivity analysis of cost ICER values were most sensitive to variations in the amount saved by SDD and the cost of bupivacaine. In probabilistic sensitivity analyses, TAP strategy was cost-effective at a willingness-to-pay threshold of $50,000/QALY in 94.5% of iterations and at a willingness-to-pay threshold of $100,000/QALY in 97.1% of iterations. Conclusions: The use of liposomal bupivacaine TAP block resulted in cost savings and improved QALYs in base case analyses and was cost-effective at conventional willingness to pay thresholds in the majority of iterations in probabilistic sensitivity analyses.

Percutaneous Cholecystostomy Tubes (PCT) have become an accepted and common modality of treating acute cholecystitis in patients that are not appropriate surgical candidates. As percutaneous gallbladder drainage has rapidly increased newer research suggests that the technique may be overused, and patients may be burdened with them for extended periods. We examined our experience with PCT placement to identify independent predictors of interval cholecystectomy versus destination PCT.All patients with cholecystitis initially treated with PCT from 2014 to 2017 were stratified by whether they underwent subsequent interval cholecystectomy. Demographic data, initial laboratory values, Tokyo Grade, Charlson Comorbidity Index, ASA Class, complications related to PCT, complications related to cholecystectomy, and mortality data were retrospectively collected. Descriptive statistics, univariable, and multivariable Poisson regression were performed.165 patients received an initial cholecystostomy tube to treat cholecystitis. 61 (37%) patients went on to have an interval cholecystectomy. There were 4 complications reported after cholecystectomy. A total of 46 (27.9%) deaths were reported, only one of which was in the cholecystectomy group. Age, Tokyo Grade, liver function tests, ASA Class, and Charlson Comorbidity Index were significantly different between the interval cholecystectomy and no-cholecystectomy groups. Univariable regression was performed and variables with p 0.2 were included in the multivariable model. Multivariable Poisson regression showed that increasing Tokyo Grade (IRR 0.454, p = 0.042, 95% CI 0.194-0.969); and increasing Charlson Comorbidity Score (IRR 0.890, p = 0.026, 95% CI 0.803-0.986) were associated with no-cholecystectomy. Higher Albumin (IRR 1.580, p = 0.011, 95% CI 1.111-2.244) was associated with having an interval cholecystectomy.Patients in the no-cholecystectomy group were older, had more comorbidities, higher Tokyo Grade, ASA Class, and initial liver function test values than those that had interval cholecystectomy. Since interval cholecystectomy was performed with a low rate of complications, we may be too conservative in performing cholecystectomy after drainage and condemning many patients to destination tubes.

Objective Intensive care units (ICUs) increasingly rely on advanced practice providers (APPs) to care for critically ill patients. Our institutional APPs perceived functional anatomical knowledge deficits. To meet this need, a cadaver-based prosection course was developed. The purpose of our study was to describe and evaluate the learner-perceived course efficacy. Design A precourse survey collected participant demographics. Precourse and postcourse surveys assessed perceived confidence in 13 anatomical areas. The postcourse survey also evaluated preparedness to perform ICU procedures and to care for postoperative patients, and additionally, gauged participant satisfaction and opinions. Summary statistics and pre-post survey comparisons were performed using Stata 14.0. Participants Twenty-five APPs, all Advanced Practice Registered Nurse certified and working within our tertiary care ICUs, completed the course. Participants practiced in a variety of ICUs, inclusive of neurologic/neurosurgical (4.0%), burn (8.0%), medical (12.0%), trauma (28.0%) and surgical (48.0%), and typically held a Masters of Science in Nursing as his/her highest attained degree. Experience levels ranged from 0 to 8 years. Results Precourse survey results confirmed perceived anatomical knowledge deficits, noting median APP scores 3.00 or less, correlating to neutral to very little confidence, in all 13 queried anatomical areas. Wilcoxon signed-rank statistical analysis revealed significantly improved confidence level in anatomic knowledge following course completion in all 13 anatomical areas. Aligning with the improved confidence, most participants felt they were better prepared to perform ICU procedures and care for patients following operative intervention. Conclusion Cadaver-based anatomical training has significant benefit to ICU APPs perceived knowledge and performance.

This ballistics study examines whether saline breast implants can decrease tissue penetration in firearm injuries. We hypothesize that the fluid column within a saline breast implant can alter bullet velocity and/or bullet pattern of mushrooming. The two experimental groups included saline implants with 7.4 cm projection and a no implant group. The experimental design allowed the bullet to pass-through an implant and into ballistics gel (n = 10) or into ballistics gel without passage through an implant (n = 11). Shots that passed through an implant had 20.6% decreased penetration distance when compared to shots that did not pass-through an implant; this difference was statistically significant (31.9 cm vs. 40.2 cm, p < 0.001). Implant group bullets mushroomed prior to gel entry, but the no implant group mushroomed within the gel. Bullet passage through a saline breast implant results in direct bullet velocity reduction and earlier bullet mushrooming; this causes significantly decreased ballistics gel penetration.

BackgroundThe effectiveness of the nonsteroidal anti-inflammatory drug ketorolac in reducing pulmonary morbidity after rib fractures remains largely unknown.MethodsA retrospective cohort study was conducted spanning January 2003 to June 2011 assessing pneumonia within 30 days and potential adverse effects of ketorolac among all patients with rib fractures who received ketorolac

Background The benefits of Tactical Emergency Medical Support (TEMS) elements are providing injury prevention, immediate care of injuries, and medical augmentation of the success of dangerous law enforcement operations. TEMS is recognized by civilian Special Weapons and Tactics (SWAT) and various other law enforcement agencies around the country as a vital addition to such SWAT teams. The integration of specially trained TEMS personnel has become a key component of law enforcement special operations. Objective Our aim was to review the published literature to identify if there is a role for physicians within TEMS elements with regard to its establishment and progression, and to characterize the level of physician-specific support provided in the tactical environment for civilian tactical law enforcement teams. Discussion Physician presence as part of TEMS elements is increasing in number and popularity as the realization of the benefits provided by such physicians has become more apparent. The inclusion of physicians as active and participating members of TEMS elements is a critical measure to be taken for tactical law enforcement units. Physicians provide an added level of medical expertise to TEMS elements in rural and urban settings compared with law enforcement personnel with medic training. Conclusions Physician involvement is an essential element of a successful TEMS program. There is a need for more physicians to become involved as TEMS personnel for specialized tactical teams to spread the time commitment and increase their availability to tactical units on a daily basis.

Obtaining vascular access in critically ill patients is one of the most important elements of clinical care; however, critically ill patients often have factors that complicate obtaining access which can create significant challenges for providers at all levels of experience. IV access is critical for many reasons including the administration intravenous fluids, blood products, medications (some medications require central access for administration), hemodynamic monitoring, drawing blood, hemodialysis, and for the administration of IV contrast used for both diagnostic and therapeutic procedures. This chapter discusses challenging IV access in the patient with septic shock; however, this information may apply to other types of critically ill patients and is presented in two sections; section “Types of Intravenous Access” discusses types of IV access such as peripheral, peripherally inserted central access, central, intraosseous, and concludes with venous cutdown, and section “Special Considerations in Difficult Clinical Settings” discusses special considerations in difficult clinical settings such as coagulopathy, venous thrombosis/occlusion, chronic kidney diseases/hemodialysis patients, morbidly obese patients, and burn patients.

This observational study characterized medication use in the immediate postoperative period among patients undergoing total hip arthroplasty (THA) at an academic medical center, and evaluated pain (0-10 numerical pain rating scale [NPRS]; 0 = no pain, 10 = worst pain that the patient can imagine), function (Harris Hip Score [HSS]and Lower Extremity Function Scale [LEFS]), and health-related quality of life (SF-36). Study patients (N = 115; 59% female; average age 61.3 ± 12.0 years; mean BMI of 29.9 ± 6.9 kg/m2) who underwent THA between September 1, 2008, and November 30, 2010, and met study inclusion criteria were drawn from the University of Utah Orthopedic Clinic database. The most common comorbidities in these patients were osteoarthritis, hypertension, and chronic back pain. The most frequently prescribed class of pain-related medications in the immediate postoperative period was opioids. The most common nonopioid medications were bupivacaine, celecoxib, and midazolam. Opioids and celecoxib continued to be commonly prescribed at discharge. Pain was improved at a 6-week follow-up (mean change −3.3 ± 3.3 points), as were HSS and LEFS, with mean changes of 19.9 ± 24.2 and 8.7 ± 16.9 points (P.01 for both), respectively. Although SF-36 scores were also improved, these scores were significantly lower relative to normative values for the US general population as well as relative to individuals having both osteoarthritis and hypertension.

To assess if implementing Nighttime Nurse and Physician Paging System (NNAPPS) would improve nurse and physician communication as well as reduce the number of nonurgent pages to residents taking overnight call.NNAPPS was implemented on the busiest General Surgery and Transplant wards at our University Hospital. We conducted 2 prospective studies that logged pages received by on call surgery residents for 2-month blocks. The logs captured time, source, reason, and action resulting from pages. Independent reviewers determined urgency of the pages. Primary outcome measures were comparison of average nonurgent pages, total pages and total pages per patient during a night shift between the NNAPPS ward and all other wards that care for surgical patients.University teaching hospital.General surgery residents working overnight call shifts on nine surgical services.In both studies combined, there were a total of 107 night shifts during which 771 pages were received. Total census was 1179 patients. Nurses initiated most pages (67%). Eight percent of pages interrupted patient care, while 40% of pages interrupted resident sleep. Most pages resulted in either a "new order" (39%) or "patient assessment" (22%), while 36% resulted in "no action." Most pages (56%) were "urgent," 25% "nonurgent," and 19% "unable to determine urgency." Regarding the Transplant ward, significant differences (p0.05) existed between average nonurgent pages (0.46 vs 2.14), total pages (3.69 vs 6.14) and total pages/patient during a shift (0.38 vs 0.68) when comparing pre- and post-NNAPPS data.NNAPPS significantly reduced nonurgent pages, total pages and pages per patient during a night shift compared to services with conventional systems. Streamlined paging systems lead to more efficient communication between providers and decrease the nonurgent pages to residents. NNAPPS continued high standards of patient care and improved sleep patterns for residents.

To assess the contemporary epidemiology of blunt trauma lower urinary tract injury (LUTI) and to evaluate outcomes in patients with and without associated pelvic fracture (PF).Patients presenting to our level I trauma center with PF and/or LUTI from blunt trauma from 2000 to 2014 were identified in our institutional trauma registry. Demographics, mechanism of injury, fracture configurations, hospital course, and outpatient disposition were analyzed.Of 5518 PF patients, 233 (4.2%) had LUTI. Thirty-four patients had non-PF LUTI. There were 3.2% of men and 3.3% of women with PF who had bladder injuries (P = .94). Urethral injury was more common in men (2.0% vs 0.05%; relative risk 43.1). Pubic arch fractures were present in 87% of patients with urethral injuries, although only 1.5% of patients with pubic arch fractures had urethral injury. Isolated acetabular fractures were never associated with urethral injury and associated with only 2.6% of bladder injuries. Extraperitoneal bladder ruptures were more common in the PF group as compared to the non-PF LUTI group (39.1% vs 14.7%, P .01). Intensive care unit length of stay and hospital length of stay for PF vs non-PF patients were 7.1 ± 8.1 vs 2.8 ± 5.3 days (P .01) and 13.5 ± 13.4 vs 7.7 ± 8.4 days (P = .01), respectively.These data suggest that the contemporary incidence of PF LUTI is lower than previously reported. The presence of PF in patients with LUTI is associated with more severe overall injuries, longer hospital stays, and increased rates of inpatient complications.

Introduction Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) can be challenging to treat due to pain with wound care and ongoing fluid loss. The purpose of this study is to determine the role of porcine xenograft as a modality for wound coverage. Material and Methods A retrospective review from 2006 to 2014 was performed at a regional burn center on all patients admitted with the diagnosis of SJS ( 30% TBSA involvement). Patients who received porcine xenograft had physiologic and biochemical parameters compared in the 24 h before and after graft placement. In addition, xenograft patients were compared to historical controls that received traditional wound care which included silver impregnated dressings. Outcomes and variables collected included intravenous fluid given, urine output, pain scores (1–10), pain medication for wound care, biochemical markers, skin infections, hospital length of stay, and mortality. Results Eight patients had placement of a porcine xenograft. Median age was 50 years (IQR 41, 66) and 2 were male. Median % TBSA affected was 76 (IQR 64, 80). The median amount of fluid (ml/kg/day/%TBSA) administered decreased from 1.45 (IQR 1.03, 1.78) to 0.9 (IQR 0.65, 1.08) after xenograft placement (p = 0.02). The median amount of intravenous fluid (ml/kg/day/%TBSA) administered in the treatment group and historical control group was 0.9 (IQR 0.65, 1.08) and 0.8 (IQR 0.7, 1.47) respectively (p = 0.72). The median amount of urine output (ml/kg/day) in the treatment group and historical control group was 34.2 (IQR 22, 44.38) and 22 (IQR 11.25, 38.13) respectively (p = 0.17). Pain scores significantly decreased from 5.5 (IQR 2.5, 8.25) pre-xenograft to 2.8 (IQR 0.75, 4) post-xenograft placement (p = 0.03). There was a significant difference in pain scores between the treatment group and historical control group, 2.8 (IQR 0.75, 4) and 6 (IQR 5, 8) respectively (p = 0.02). Each study patient underwent moderate sedation for wound care prior to xenograft placement and one study patient required one moderate sedation for wound care after xenograft placement. One patient in the xenograft placement group was diagnosed with a cutaneous infection compared to 4 patients in the historical control group (p = 0.63). The mortality was 12.5% in each group. Conclusions Placement of a porcine xenograft in patients with SJS, SJS/TEN overlap, or TEN is associated with a significant reduction in intravenous fluid use, pain scores, and pain medication. Further study with larger sample sizes is warranted to evaluate for statistically significant differences in outcomes after porcine xenograft placement for SJS, SJS/TEN overlap or TEN.

Objectives To evaluate the medical professionals and medical students perceived usefulness of an emergency medical card (EMC) and a continuity of care (CoC) report, in enhancing CoC. Methods The study reviewers included medical professionals from outpatient clinics at Intermountain Healthcare and fourth-year medical students from the University of Utah. Three cases we randomly extracted from a database of patients who had added new care information at the time. EMCs and CoC reports were populated for the cases, and information then de-identified. Using patient information in the electronic medical record (EMR), reviewers evaluated if the EMR information was adequate to support medical decisions made on the patient's diagnosis, medications, laboratory tests, and disposition. The reviewer assessed if the EMC and CoC report information would influence the medical decisions made. An online survey was used to assess the reviewers’ perception on the usefulness of the two documents. Results On average, 94% of the reviewers perceived the EMC to be useful in enhancing medical decision making at the point of care, and 74% found the CoC report to be useful. More specifically, the two documents were found to be useful in decreasing encounter time (100% each), increasing overall knowledge of healthcare providers (100% each), influencing decision on the treatment (94% each), and new laboratory test orders (87% and 90%, respectively). Conclusions The EMC and CoC report were found to be useful methods for transporting patient healthcare information across the healthcare continuum. The documents were found more specifically to be useful for effective decision making, improving efficiency and quality of care, at the point of care.

Metabolic acidosis has been implicated in the development of coagulopathy, although the specific mechanisms have not been well characterized. We sought to explore whether resuscitation of injured patients with a balanced crystalloid solution affects coagulation, as measured by endogenous thrombin potential (ETP) and thromboelastography (TEG). We performed an exploratory analysis of a subset of subjects enrolled in a randomized trial comparing the effect of resuscitation with isotonic saline versus Plasma-Lyte A (PLA) on acidosis and electrolyte abnormalities. We collected plasma at admission and 6 h later for subsequent ETP and TEG analysis and compared subjects receiving isotonic saline to those receiving PLA. Among 18 evaluated subjects, baseline characteristics, including ETP and TEG parameters, were similar between the two arms. At 6 h, subjects receiving isotonic saline were more acidemic. At 6 h, there were no differences in ETP parameters between groups; however, TEG results showed the time from initial clot formation to an amplitude of 20 mm (K) was shorter (3.8 ± 2.1 vs. 7.2 ± 2.8 s) and the rapidity of fibrin build-up and cross-linking (α angle) was significantly greater (41 ± 8 vs. 24 ± 15 deg) for the PLA group than in the isotonic saline group. Relative to PLA, isotonic saline does not alter thrombin generation, but isotonic saline and PLA may differentially impact clotting factor availability. The shorter time to reach prespecified clot amplitude and the increased rate of fibrin generation imply faster amplification of clotting factors with PLA without effect on latency time or clot strength.

Studies on infectious diseases have helped us understand the extent to which public health systems would benefit from mapping the real-time distribution, condition and treatment efficacy of infectious diseases. Evidence suggests there is deficiency in timely and relevant geographic information that is undermining clinical, epidemiological and public health aspirations in areas affected with epidemic-prone diseases. Data Mural's proprietary platform uses the latest in mapping and spatial visualization tools, big data analytics, data mining methods and processes.

BACKGROUND: In medical settings, motivational interviewing-based "brief intervention" (BI) counseling reduces alcohol-related risk-taking behavior and harm in high-risk populations. Individuals arrested for driving under the influence of alcohol (DUI) are another at-risk population. We sought to determine whether a BI administered shortly after a first DUI arrest might decrease problematic drinking behavior. METHODS: We conducted a single-center, parallel-group, double-blinded superiority randomized trial (NCT01270217), enrolling first-time DUI arrestees at a county jail from December 2010 through April 2011. Before their release, we randomized participants by computer-generated sequence to either a single BI or no discussion. We assessed 90-day change in Alcohol Use Disorders Identification Test (AUDIT) scores (range 0-40, higher values indicating more problematic drinking) as the primary outcome. RESULTS: We enrolled 200 subjects (100 to each arm), and 181 (90.5%, 86 control and 95 BI) completed the 90-day follow-up. Mean (SD) age was 30 (10) years, and 50% were men. Mean (SD) blood alcohol concentration upon arrest was 0.14% (0.04%). Mean (SD) baseline AUDIT scores were 8.8 (5.8) among control subjects and 7.7 (6.3) among BI subjects. At 90 days, AUDIT scores decreased by a mean (SD) 4.7 (5.1) units among control subjects and 3.4 (5.0) among BI subjects (difference, -1.3; 95% confidence interval [CI], -2.8 to +0.1). The likelihood of subsequent binge drinking [relative risk (RR) 1.6; 95% CI, 0.8-3.0; BI vs. control], abstinence (RR, 0.9; 95% CI, 0.4-2.1), alcohol-related injury to self or others (RR, 0.4; 95% CI, 0.1-2.4), and seeking treatment (RR, 1.2; 95% CI, 0.8-1.7) did not differ. CONCLUSION: A single BI counseling session shortly after first-time DUI arrest does not reduce 90-day self-reported drinking behavior or increase seeking treatment for drinking beyond that which occurs without such a discussion.

To use a case report of a complex cardiac injury case to illustrate how civilian trauma can be used to train combat general surgeons.We report the case of a 23-year-old man who suffered three penetrating injuries to the left ventricle (LV) after multiple stab wounds to left chest. On hospital arrival he was conversant, hemodynamically stable, oxygenating well, and without signs of cardiac tamponade. He deteriorated and required an urgent exploratory thoracotomy. Intraoperatively, 2-, 3.5-, and 5-cm stellate lacerations were discovered in the LV near the aortic root, of which, two were full thickness. A simple pledgeted horizontal mattress suture was not sufficient to repair the injuries. The repair ultimately required a running polypropylene suture to control the hemorrhage. The patient was awake on postoperative day 0 and discharged on postoperative day 12 without significant complication.This case illustrates several points for the combat surgeon. First, young men are able to tolerate catastrophic injuries, presenting with normal hemodynamics. Second, there are a variety of techniques to use when treating uncommon injuries. Finally, the surgeon needs the ability to improvise quickly and to apply surgical techniques to treat complex traumatic injuries successfully.

Members of Special Weapons and Tactics (SWAT) teams routinely work in high-risk tactical situations. Awareness of the benefit of Tactical Emergency Medical Support (TEMS) is increasing but not uniformly emphasized.To characterize the current regional state of tactical medicine and identify potential barriers to more widespread implementation.A multiple-choice survey was administered to SWAT team leaders of 22 regional agencies in northern and central California. Questions focused on individual officer self-aid and buddy care training, the use and content of individual first aid kits (IFAKs), and the operational inclusion of a dedicated TEMS provider.Respondents included city police (54%), local county sheriff (36%), state law enforcement (5%), and federal law enforcement (5%). RESULTS showed that 100% of respondents thought it was ?Very Important? for SWAT officers to understand the basics of self-aid and buddy care and to carry an IFAK, while only 71% of respondents indicated that team members actually carried an IFAK. In addition, 67% indicated that tourniquets were part of the IFAK, and 91% of surveyed team leaders thought it was ?Very Important? for teams to have a trained medic available onsite at callouts or high-risk warrant searches. Also, 59% of teams used an organic TEMS element.The majority of SWAT team leaders recognize the benefit of basic Operator medical training and the importance of a TEMS program. Despite near 100% endorsement by unit-level leadership, a significant proportion of teams are lacking one of the key components including Operator IFAKs and/or tourniquets. Tactical team leaders, administrators, and providers should continue to promote adequate Operator training and equipment as well as formal TEMS support.

We sought to compare resuscitation with 0.9% NaCl versus Plasma-Lyte A, a calcium-free balanced crystalloid solution, hypothesizing that Plasma-Lyte A would better correct the base deficit 24 hours after injury.Sodium chloride (0.9%) (0.9% NaCl), though often used for resuscitation of trauma patients, may exacerbate the metabolic acidosis that occurs with injury, and this acidosis may have detrimental clinical effects.We conducted a randomized, double-blind, parallel-group trial (NCT01270854) of adult trauma patients requiring blood transfusion, intubation, or operation within 60 minutes of arrival at the University of California Davis Medical Center. Based on a computer-generated, blocked sequence, subjects received either 0.9% NaCl or Plasma-Lyte A for resuscitation during the first 24 hours after injury. The primary outcome was mean change in base excess from 0 to 24 hours. Secondary outcomes included 24-hour arterial pH, serum electrolytes, fluid balance, resource utilization, and in-hospital mortality.Of 46 evaluable subjects (among 65 randomized), 43% had penetrating injuries, injury severity score was 23 ± 16, 20% had admission systolic blood pressure less than 90 mm Hg, and 78% required an operation within 60 minutes of arrival. The baseline pH was 7.27 ± 0.11 and base excess -5.9 ± 5.0 mmol/L. The mean improvement in base excess from 0 to 24 hours was significantly greater with Plasma-Lyte A than with 0.9% NaCl {7.5 ± 4.7 vs 4.4 ± 3.9 mmol/L; difference: 3.1 [95% confidence interval (CI): 0.5-5.6]}. At 24 hours, arterial pH was greater [7.41 ± 0.06 vs 7.37 ± 0.07; difference: 0.05 (95% CI: 0.01-0.09)] and serum chloride was lower [104 ± 4 vs 111 ± 8 mEq/L; difference: -7 (95% CI: -10 to -3)] with Plasma-Lyte A than with 0.9% NaCl. Volumes of study fluid administered, 24-hour urine output, measures of resource utilization, and mortality did not significantly differ between the 2 arms.Compared with 0.9% NaCl, resuscitation of trauma patients with Plasma-Lyte A resulted in improved acid-base status and less hyperchloremia at 24 hours postinjury. Further studies are warranted to evaluate whether resuscitation with Plasma-Lyte A improves clinical outcomes.
