RESUMO

BACKGROUND: Five million people die annually due to injuries; an increasing part is due to armed conflict in low-income and middle-income countries, demanding resolute emergency trauma care. In Afghanistan, a low-income country that has experienced conflict for over 35 years, conflict related trauma is a significant public health problem. To address this, the non-governmental organisation Médecins Sans Frontières (MSF) set up a trauma centre in Kunduz (Kunduz Trauma Centre (KTC)). MSF's standardised emergency operating procedures include the South African Triage Scale (SATS). To date, there are few studies that assess how triage levels correspond with outcome in low-resource conflict settings AIM: This study aims to assess to what extent SATS triage levels correlated to outcomes in terms of hospital admission, intensive care unit (ICU) admission and mortality for patients treated at KTC. METHOD AND MATERIALS: This retrospective study used routinely collected data from KTC registries. A total of 17 970 patients were included. The outcomes were hospital admission, ICU admission and mortality. The explanatory variable was triage level. Covariates including age, gender and delay to arrival were used. Logistic regression was used to study the correlation between triage level and outcomes. RESULTS: Out of all patients seeking care, 28.7% were triaged as red or orange. The overall mortality was 0.6%. In total, 90% of those that died and 79% of ICU-admitted patients were triaged as red. CONCLUSION: The risk of positive and negative outcomes correlated with triage level. None of the patients triaged as green died or were admitted to the ICU whereas 90% of patients who died were triaged as red.

RESUMO

BACKGROUND: Populations at risk during humanitarian crises can suffer traumatic injuries or have medical conditions that result in the need for limb amputation (LA). The objectives of this study were to describe the indications for and associations with LA during and after humanitarian crises in surgical projects supported by Médecins Sans Frontières (MSF). METHODS: MSF-Operational Center Brussels data from January 1, 2008, to December 31, 2017, were analyzed. Surgical projects were classified into (annual) periods of crises and post-crises. Indications were classified into trauma (intentional and unintentional) and non-trauma (medical). Associations with LA were also reported. RESULTS: MSF-OCB performed 936 amputations in 17 countries over the 10-year study period. 706 (75%) patients were male and the median age was 27 years (interquartile range 17-41 years). Six hundred and twenty-one (66%) LA were performed during crisis periods, 501 (53%) during conflict and 119 (13%) post-natural disaster. There were 316 (34%) LA in post-crisis periods. Overall, trauma was the predominant indication (n = 756, 81%) and accounted for significantly more LA (n = 577, 94%) in crisis compared to post-crisis periods (n = 179, 57%) (p < 0.001). DISCUSSION: Our study suggests that populations at risk for humanitarian crises are still vulnerable to traumatic LA. Appropriate operative and post-operative LA management in the humanitarian setting must be provided, including rehabilitation and options for prosthetic devices.

RESUMO

BACKGROUND: Médecins Sans Frontières (MSF) provides surgical care in fragile states, which are more vulnerable to conflict. The primary objective of this study was to compare the indications for operative intervention in surgical projects in fragile states during periods of active conflict (CON) and non-conflict (NON-CON). In addition, risk factors for non-obstetric and obstetric operative mortality were identified. METHODS: This was a retrospective analysis of MSF surgical projects in fragile states January 1, 2008-December 31, 2017. Variables considered in the analysis include age, gender, American Society of Anesthesiology physical status, emergency status, re-intervention status, indication for surgical intervention, and conflict/non-conflict time period. RESULTS: There were 30 surgical projects in 13 fragile states with 87,968 surgical interventions in 68,667 patients. Obstetric needs were the most common indication for surgical intervention (n = 28,060, 31.9%) but were more common during NON-CON (n = 23,142, 35.7%) compared to CON periods (n = 4,918, 21.2%, p < 0.001). Trauma was more common during CON (42.0%) compared to NON-CON (23.0%) periods (p < 0.001). Non-obstetric operative mortality was similar during CON (0.2%) compared to NON-CON (0.2%, p = 0.920), but obstetric operative mortality was higher (0.5%) during CON compared to NON-CON (0.2%, p < 0.001) periods. Risk factors for obstetric and non-obstetric mortality included age ≥ 30 years, ASA greater than 1, and emergency intervention. CONCLUSION: Humanitarian surgeons working in fragile states should be prepared to treat a range of surgical needs including trauma and obstetrics during conflict and non-conflict periods. The mortality in obstetric patients was higher during conflict periods, and further research to understand ways to protect this vulnerable group is needed.

RESUMO

BACKGROUND: Armed conflicts constitute a significant public health problem, and the advent of asymmetric warfare tactics creates unique and new challenges to health care organizations providing trauma care in conflicts. OBJECTIVE: This study aimed to analyze the epidemiology of presentations to a civilian field hospital deployed close to an ongoing conflict. METHODS: During the 2016-2017 Mosul offensive, the humanitarian organization Médecins Sans Frontières deployed a field hospital 30 km south of Mosul. This study is a retrospective analysis of routinely collected patient data of all presentations to the emergency department (ED) during its period of operation between February 23 and July 18, 2017. Data were collected in Microsoft Excel by health care workers and analyzed in JMP, version 13. Chi-square test was used to compare proportions. A p value < 0.05 was considered significant. RESULTS: The analysis included 3946 presentations. Most were due to conflict-related injuries, including explosives (40.4%) and firearms (12.9%), which presented in consecutive waves over time. Approximately one-third of presentations (32.3%) were due to medical issues, which outweighed conflict-related presentations toward the latter half of the operational period. Explosives caused most of the mass casualty events. A total of 20 patients (0.5%) died in the ED. CONCLUSIONS: The study demonstrated a cyclical burden of conflict-related injuries and extensive medical needs, which increased over time. Among conflict-related injuries, explosive etiology predominated and was likely to result in mass casualty incidents. The low mortality might be due to critical but potentially salvageable patients not reaching the hospital in time, owing to the adverse context.

RESUMO

BACKGROUND: Humanitarian medical organizations provide surgical care for a broad range of conditions including general surgical (GS), obstetric and gynecologic (OBGYN), orthopedic (ORTHO), and urologic (URO) conditions in unstable contexts. The most common humanitarian operation is cesarean section. The objective of this study was to identify the proportion of South African general surgeons who had operative experience and current competency in GS, OBGYN, ORTHO, and URO humanitarian operations in order to evaluate their potential for working in humanitarian disasters. METHODS: This was a cross-sectional online survey of South African general surgeons administered from November 2017-July 2018. Rotations in OBGYN, ORTHO, and URO were quantified. Experience and competency in eighteen humanitarian operations were queried. RESULTS: There were 154 SA general surgeon participants. Prior to starting general surgery (GS) residency, 129 (83%) had OBGYN, 125 (81%) ORTHO, and 84 (54%) URO experience. Experience and competency in humanitarian procedures by specialty included: 96% experience and 95% competency for GS, 71% experience and 51% competency for OBGYN, 77% experience and 66% competency for ORTHO, and 86% experience and 81% competency for URO. 82% reported training, and 51% competency in cesarean section. CONCLUSIONS: SA general surgeons are potentially well suited for humanitarian surgery. This study has shown that most SA general surgeons received training in OBGYN, ORTHO, and URO prior to residency and many maintain competence in the corresponding humanitarian operations. Other low- to middle-income countries may also have broad-based surgery training, and the potential for their surgeons to offer humanitarian assistance should be further investigated.

RESUMO

INTRODUCTION: There is paucity of literature describing type of injury and care for females in conflicts. This study aimed to describe the injury pattern and outcome in terms of surgery and mortality for female patients presenting to Médecins Sans Frontières Trauma Centre in Kunduz, Afghanistan, and compare them with males. MATERIALS AND METHODS: This study retrospectively analysed patient data from 17,916 patients treated at the emergency department in Kunduz between January and September 2015, before its destruction by aerial bombing in October the same year. Routinely collected data on patient characteristics, injury patterns, triage category, time to arrival and outcome were retrieved and analysed. Comparative analyses were conducted using logistic regression. RESULTS: Females constituted 23.6% of patients. Burns and back injuries were more common among females (1.4% and 3.3%) than among males (0.6% and 2.0%). In contrast, open wounds and thoracic injuries were more common among males (10.1% and 0.6%) than among females (5.2% and 0.2%). Females were less likely to undergo surgery (OR 0.60, CI 0.528-0.688), and this remained significant after adjustment for age, nature of injury, triage category, multiple injuries and delay to arrival (OR 0.80, CI 0.690-0.926). Females also had lower unadjusted odds of mortality (OR 0.49, CI 0.277-0.874), but this was not significant in the adjusted analysis (OR 0.81, CI 0.446-1.453). CONCLUSION: Our main findings suggest that females seeking care at Kunduz Trauma Centre arrived later, had different injury patterns and were less likely to undergo surgery as compared to males.

RESUMO

BACKGROUND: Bleeding is an important cause of death in trauma victims. In 2010, the CRASH-2 study, a multicentre randomized control trial on the effect of tranexamic acid (TXA) administration to trauma patients with suspected significant bleeding, reported a decreased mortality in randomized patients compared to placebo. Currently, no evidence on the use of TXA in humanitarian, low-resource settings is available. We aimed to measure the hospital outcomes of adult patients with severe traumatic bleeding in the Médecins Sans Frontières Tabarre Trauma Centre in Port-au-Prince, Haiti, before and after the implementation of a Massive Haemorrhage protocol including systematic early administration of TXA. METHODS: Patients admitted over comparable periods of four months (December2015- March2016 and December2016 - March2017) before and after the implementation of the Massive Haemorrhage protocol were investigated. Included patients had blunt or penetrating trauma, a South Africa Triage Score ≥ 7, were aged 18-65 years and were admitted within 3 h from the traumatic event. Measured outcomes were hospital mortality and early mortality rates, in-hospital time to discharge and time to discharge from intensive care unit. RESULTS: One-hundred and sixteen patients met inclusion criteria. Patients treated after the introduction of the Massive Haemorrhage protocol had about 70% less chance of death during hospitalization compared to the group "before" (adjusted odds ratio 0.3, 95%confidence interval 0.1-0.8). They also had a significantly shorter hospital length of stay (p = 0.02). CONCLUSIONS: Implementing a Massive Haemorrhage protocol including early administration of TXA was associated with the reduced mortality and hospital stay of severe adult blunt and penetrating trauma patients in a context with poor resources and limited availability of blood products.

RESUMO

BACKGROUND: Effective humanitarian surgeons require skills in general surgery, OB/GYN, orthopedics, and urology. With increasing specialization, it is unclear whether US general surgery residents are receiving exposure to these disparate fields. We sought to assess the preparedness of graduating American surgical residents for humanitarian deployment. METHODS: We retrospectively analyzed cases performed by American College of Graduate Medical Education general surgery graduates from 2009 to 2015 and cases performed at select Médecins Sans Frontières (MSF) facilities from 2008 to 2012. Cases were categorized by specialty (general surgery, orthopedics, OB/GYN, urology) and compared with Chi-squared testing. Non-operative care including basic wound and drain care was excluded from both data sets. RESULTS: US general surgery residents performed 41.3% MSF relevant general surgery cases, 1.9% orthopedic cases, 0.1% OB/GYN cases, and 0.3% urology cases; the remaining 56.4% of cases exceeded the standard MSF scope of care. In comparison, MSF cases were 30.1% general surgery, 21.2% orthopedics, 46.8% OB/GYN, and 1.9% urology. US residents performed fewer OB/GYN cases (p < 0.01) and fewer orthopedic cases (p < 0.01). Differences in general surgery and urology caseloads were not statistically significant. Key procedures in which residents lacked experience included cesarean sections, hysterectomies, and external bony fixation. CONCLUSION: Current US surgical training is poorly aligned with typical MSF surgical caseloads, particularly in OB/GYN and orthopedics. New mechanisms for obtaining relevant surgical skills should be developed to better prepare American surgical trainees interested in humanitarian work.

RESUMO

BACKGROUND: Surgical infections represent a substantial yet undefined burden of disease in low-income and middle-income countries (LMICs). Médecins Sans Frontières (MSF) provides surgical care in LMICs and collects data useful to describe the operative epidemiology of surgical need that would otherwise be unmet by national health services. We aimed to describe the experience of MSF Operations Centre Brussels surgery for infections during crisis; aid effective resource allocation; prepare humanitarian surgical staff; and further characterise unmet surgical needs in LMICs. METHODS: We reviewed all procedures undertaken in operating theatres at facilities run by the MSF Operations Centre Brussels between July, 2008, and June, 2014. Projects providing only specialty care were excluded. Procedures for infections were quantified, related to demographics and reason for humanitarian response was described. FINDINGS: 96 239 operations were undertaken at 27 MSF Operations Centre Brussels sites in 15 countries. Of 61 177 general operations, 7762 (13%) were for infections. Operations for skin and soft tissue infections were the most common (64%), followed by intra-abdominal (26%), orthopaedic (6%), and tropical infections (3%). The proportion of operations for skin and soft tissue infections was highest during natural disaster missions, intra-abdominal infections during hospital support missions, and orthopaedic infections during conflict missions. Most procedures for skin and soft tissue infections were minor (76%), whereas most operations for intra-abdominal infections were major (98%). INTERPRETATION: Surgical infections are among the most common causes for operation in LMICs. Although many procedures were minor, they represent substantial use of perioperative resources. Growing evidence shows the need for improved perioperative capacity to aptly care for the volume and variety of conditions comprising the global burden of surgical disease. FUNDING: Médecins Sans Frontières.

RESUMO

BACKGROUND: Anesthesia is integral to improving surgical care in low-resource settings. Anesthesia providers who work in these areas should be familiar with the particularities associated with providing care in these settings, including the types and outcomes of commonly performed anesthetic procedures. METHODS: The authors conducted a retrospective analysis of anesthetic procedures performed at Médecins Sans Frontières facilities from July 2008 to June 2014. The authors collected data on patient demographics, procedural characteristics, and patient outcome. The factors associated with perioperative mortality were analyzed. RESULTS: Over the 6-yr period, 75,536 anesthetics were provided to adult patients. The most common anesthesia techniques were spinal anesthesia (45.56%) and general anesthesia without intubation (33.85%). Overall perioperative mortality was 0.25%. Emergent procedures (0.41%; adjusted odds ratio [AOR], 15.86; 95% CI, 2.14 to 115.58), specialized surgeries (2.74%; AOR, 3.82; 95% CI, 1.27 to 11.47), and surgical duration more than 6 h (9.76%; AOR, 4.02; 95% CI, 1.09 to 14.88) were associated with higher odds of mortality than elective surgeries, minor surgeries, and surgical duration less than 1 h, respectively. Compared with general anesthesia with intubation, spinal anesthesia, regional anesthesia, and general anesthesia without intubation were associated with lower perioperative mortality rates of 0.04% (AOR, 0.10; 95% CI, 0.05 to 0.18), 0.06% (AOR, 0.26; 95% CI, 0.08 to 0.92), and 0.14% (AOR, 0.29; 95% CI, 0.18 to 0.45), respectively. CONCLUSIONS: A wide range of anesthetics can be carried out safely in resource-limited settings. Providers need to be aware of the potential risks and the outcomes associated with anesthesia administration in these settings.

RESUMO

BACKGROUND: Surgical site infections (SSI) are a significant cause of post-surgical morbidity and mortality and can be an indicator of surgical quality. The objectives of this study were to measure post-operative SSI after cesarean section (CS) at four sites in three sub-Saharan African countries and to describe the associated risk factors in order to improved quality of care in low and middle income surgical programs. METHODS: This study included data from four emergency obstetric programs supported by Medecins sans Frontieres, from Burundi, the Democratic Republic of Congo (DRC), and Sierra Leone. Women undergoing from August 1 2010 to January 31 2011 were included. CS post-operative SSI data were prospectively collected. Logistic regression was used to model SSI risk factors. FINDINGS: In total, 1,276 women underwent CS. The incidence of SSI was 7.3 % (range 1.7-10.4 %). 93 % of SSI were superficial. The median length of stay of women without SSI was 7 days (range 3-63 days) compared to 21 days (range 5-51 days) in those with SSI (p < 0.001). In multivariate analysis, younger age, premature rupture of the membranes, and neonatal death were associated with an increased risk of SSI, while antenatal hemorrhage and the Lubutu, DRC project site were associated with a lower risk of developing an SSI. CONCLUSIONS: This study demonstrates that surgery can be performed with a low incidence of SSI, a proxy for surgical safety, in sub-Saharan Africa. Protocols such as perioperative antibiotics and basic infrastructure such as clean water and sterilization can be achieved. Simple data collection tools will assist policymakers with monitoring and evaluation as well as quality control assurance of surgical programs in low and middle income countries.

RESUMO

BACKGROUND: As the demographic transition occurs across developing countries, an increasing number of elderly individuals are affected by disasters and conflicts. This study aimed to evaluate the elderly population that underwent an operative procedure at MSF facilities. METHODS: A retrospective review of prospectively collected operative cases performed at MSF-Operational Centre Brussels (MSF-OCB) facilities between June 2008 and December 2012 was completed. Baseline demographic data, American Society of Anesthesiologists (ASA) physical status and surgical indications were collected for each patient. For each procedure, the degree of urgency, anesthesia type, and intra-operative mortality were noted. All patients aged 50 and over at the time of the procedure were considered elderly, as proposed by the World Health Organization (WHO). Comparisons were made with the 18-49 age group in order to elucidate differences between older and younger individuals. RESULTS: We reviewed a total of 93,385 procedures performed on 83,911 patients in 21 different countries. Patients aged 50 and over comprised 11.5% (9,628/83,911) of all patients. While most procedures (57.6%) in the comparison group were urgent, this proportion decreased substantially in the elderly. Intra-operative mortality was considerably lower in the 50-59 group (0.12%) but increased with each age stratum. The most commonly performed surgical procedures in the elderly included herniorrhaphies, simple and extensive wound debridements, abscess incision and drainages, minor tumorectomies, and urological procedures. CONCLUSIONS: In light of the increasing elderly population in developing countries, efforts should be made to better quantify and address their surgical needs.

RESUMO

PURPOSE: Médecins sans Frontières (MSF) is one of the main providers of orthopaedic surgery in natural disaster and conflict settings and strictly imposes a minimum set of context-specific standards before any surgery can be performed. Based on MSF's experience of performing orthopaedic surgery in a number of such settings, we describe: (a) whether it was possible to implement the minimum standards for one of the more rigorous orthopaedic procedures--internal fixation--and when possible, the time frame, (b) the volume and type of interventions performed and (c) the intra-operative mortality rates and postoperative infection rates. METHODS: We conducted a retrospective review of routine programme data collected between 2007 and 2014 from three MSF emergency surgical interventions in Haiti (following the 2010 earthquake) and three ongoing MSF projects in Kunduz (Afghanistan), Masisi (Democratic Republic of the Congo) and Tabarre (Haiti). RESULTS: The minimum standards for internal fixation were achieved in one emergency intervention site in Haiti, and in Kunduz and Tabarre, taking up to 18 months to implement in Kunduz. All sites achieved the minimum standards to perform amputations, reductions and external fixations, with a total of 9,409 orthopaedic procedures performed during the study period. Intraoperative mortality rates ranged from 0.6 to 1.9 % and postoperative infection rates from 2.4 to 3.5 %. CONCLUSIONS: In settings affected by natural disaster or conflict, a high volume and wide repertoire of orthopaedic surgical procedures can be performed with good outcomes when minimum standards are in place. More demanding procedures like internal fixation may not always be feasible.

RESUMO

BACKGROUND: The purpose of this prospective study was to perform a head-to-head comparison of the two methods most frequently used for evaluation of carotid plaque characteristics: Multi-detector Computed Tomography Angiography (MDCTA) and black-blood 3 T-cardiovascular magnetic resonance (bb-CMR) with respect to their ability to identify symptomatic carotid plaques. METHODS: 22 stroke unit patients with unilateral symptomatic carotid disease and >50% stenosis by duplex ultrasound underwent MDCTA and bb-CMR (TOF, pre- and post-contrast fsT1w-, and fsT2w- sequences) within 15 days of symptom onset. Both symptomatic and contralateral asymptomatic sides were evaluated. By bb-CMR, plaque morphology, composition and prevalence of complicated AHA type VI lesions (AHA-LT6) were evaluated. By MDCTA, plaque type (non-calcified, mixed, calcified), plaque density in HU and presence of ulceration and/or thrombus were evaluated. Sensitivity (SE), specificity (SP), positive and negative predictive value (PPV, NPV) were calculated using a 2-by-2-table. RESULTS: To distinguish between symptomatic and asymptomatic plaques AHA-LT6 was the best CMR variable and presence / absence of plaque ulceration was the best CT variable, resulting in a SE, SP, PPV and NPV of 80%, 80%, 80% and 80% for AHA-LT6 as assessed by bb-CMR and 40%, 95%, 89% and 61% for plaque ulceration as assessed by MDCTA. The combined SE, SP, PPV and NPV of bb-CMR and MDCTA was 85%, 75%, 77% and 83%, respectively. CONCLUSIONS: Bb-CMR is superior to MDCTA at identifying symptomatic carotid plaques, while MDCTA offers high specificity at the cost of low sensitivity. Results were only slightly improved over bb-CMR alone when combining both techniques.

RESUMO

OBJECTIVE: To evaluate the tradeoffs between temporal and spatial resolution and contrast dosing in dynamic contrast-enhanced magnetic resonance angiography (CE-MRA). METHODS: Bilateral carotid artery aneurysms were created in a swine model. Dynamic CE-MRA using 1 mol/L gadobutrol was performed at 3 T, with high temporal (high-temp), middle temporal (mid-temp), and low temporal (low-temp) resolutions. High temporal CE-MRA was performed twice using 1 mL and 2 mL gadobutrol (2 mL/s). Middle temporal and low-temp sequences were performed once with 2 mL gadobutrol (2 mL/s). The signal-to-noise ratio (SNR) was quantitatively assessed. Blinded reads were used to qualitatively evaluate contrast dose and image quality. RESULTS: The mean SNRs of high-temp, mid-temp, and low-temp resolutions were 56.7, 47.5, and 48.1. There was no significant difference between the 3 sequences with 2 mL gadobutrol. The mean SNR of the high-temp resolution with 2 mL was significantly higher than that with 1 mL (56.7 vs 39.9). In qualitative analysis, the 3 temporal sequences with 2 mL gadobutrol showed no significant differences regarding overall image quality and diagnostic value. High temporal resolution with 2 mL consistently showed the superiority of image quality than that with 1 mL. CONCLUSIONS: High temporal dynamic CE-MRA with 2 mL (0.04 mmol/kg body weight) gadobutrol can produce consistently superior image quality over that with 1 mL (0.02 mmol/kg body weight). For a given contrast dose, the tradeoffs between temporal and spatial resolution will not result in significant differences in image quality in TWIST (time-resolved angiography with interleaved stochastic trajectories).

RESUMO

BACKGROUND: In Burundi, the annual incidence of obstetric fistula is estimated to be 0.2-0.5% of all deliveries, with 1000-2000 new cases per year. Despite this relatively high incidence, national capacity for identifying and managing obstetric fistula is very limited. Thus, in July 2010, Medecins Sans Frontieres (MSF) set up a specialised Obstetric Fistula Centre in Gitega (Gitega Fistula Centre, GFC), the only permanent referral centre for obstetric fistula in Burundi. A comprehensive model of care is offered including psychosocial support, conservative and surgical management, post-operative care and follow-up. We describe this model of care, patient outcomes and the operational challenges. METHODS: Descriptive study using routine programme data. RESULTS: Between July 2010 and December 2011, 470 women with obstetric fistula presented for the first time at GFC, of whom 458 (98%) received treatment. Early urinary catheterization (conservative management) was successful in four out of 35 (11%) women. Of 454 (99%) women requiring surgical management, 394 (87%) were discharged with a closed fistula, of whom 301 (76%) were continent of urine and/or faeces, while 93 (24%) remained incontinent of urine and/or faeces. In 59 (13%) cases, the fistula was complex and could not be closed. Outcome status was unknown for one woman. Median duration of stay at GFC was 39 days (Interquartile range IQR, 31-51 days). CONCLUSION: In a rural African setting, it is feasible to implement a comprehensive package of fistula care using a dedicated fistula facility, and satisfactory surgical repair outcomes can be achieved. Several operational challenges are discussed.

RESUMO

PURPOSE: To evaluate the differences in image quality of two macrocyclic gadolinium-based contrast agents, gadobutrol and gadoterate meglumine, using time-resolved, contrast-enhanced MR angiography (CE-MRA) in a porcine carotid artery aneurysm model and to compare image quality between dynamic and conventional, single acquisition CE-MRA. MATERIALS AND METHODS: Bilateral carotid aneurysms were created surgically in this Institutional Animal Care and Use Committee approved study. Dynamic CE-MRA studies optimized for high temporal resolution were performed at 3 Tesla. Scans using equivalently dosed (on a per mmol basis) gadobutrol and gadoterate meglumine were compared qualitatively and quantitatively in terms of contrast-to-noise ratio (CNR). Higher spatial resolution dynamic and conventional CE-MRA were also compared. RESULTS: N = 16 aneurysms were assessed. Qualitative evaluation of dynamic CE-MRA scans demonstrated a preference for gadobutrol over gadoterate meglumine. Significantly higher aneurysm CNR was found with gadobutrol (133 ± 44) versus gadoterate meglumine, the latter at both equivalent and double injection rates (94 ± 35 and 102 ± 38). In a blinded assessment, conventional CE-MRA was preferred qualitatively when compared with dynamic CE-MRA. However, dynamic CE-MRA was generally capable of providing diagnostic image quality. CONCLUSION: Gadobutrol is preferred to gadoterate meglumine for high temporal resolution dynamic CE-MRA, a fact with important clinical implications for low dose CE-MRA protocols in patients at risk for nephrogenic systemic fibrosis. Conventional high resolution CE-MRA provides superior image quality when compared with dynamic CE-MRA.

RESUMO

Humanitarian surgical programs are set up de novo, within days or hours in emergency or disaster settings. In such circumstances, insuring quality of care is extremely challenging. Basic structural inputs such as a safe structure, electricity, clean water, a blood bank, sterilization equipment, a post-anesthesia recovery unit, appropriate medications should be established. Currently, no specific credentials are needed for surgeons to operate in a humanitarian setting; the training of more humanitarian surgeons is desperately needed. Standard perioperative protocols for the humanitarian setting after common procedures such as Cesarean section, burn care, open fractures, and amputations and antibiotic prophylaxis, and post-operative pain management must be developed. Outcome data, especially long-term outcomes, are difficult to collect as patients often do not return for follow-up and may be difficult to trace; standard databases for post-operative infections and mortality rates should be established. Checklists have recently received significant attention as an instrument to support the improvement of surgical quality; knowing which items are most applicable to humanitarian settings remains unknown. In conclusion, the quality of surgical services in humanitarian settings must be regulated. Many other core medical activities of humanitarian organizations such as therapeutic feeding, mass vaccination, and the treatment of infectious diseases, such as tuberculosis and human immunodeficiency virus, are subject to rigorous reporting of quality indicators. There is no reason why surgery should be exempted from quality oversight. The surgical humanitarian community should pull together before the next disaster strikes.
