Impact of Continuous Ketamine Infusion Versus Alternative Regimens on Mortality Among Burn Intensive Care Unit Patients: Implications for Prolonged Field Care.

The military is rapidly moving into a battlespace in which prolonged holding times in the field are probable. Ketamine provides hemodynamic support and has analgesic properties, but the safety of prolonged infusions is unclear. We compare in-hospital mortality between intubated burn intensive care unit (ICU) patients receiving prolonged ketamine infusion lasting =7 days or until death versus controls. We conducted a before/after cohort study of patients undergoing admission to a burn ICU with intubation within the first 24 hours as part of treatment for thermal burns. In January 2012, this ICU implemented a novel continuous ketamine infusions protocol. We performed a preintervention and postintervention cohort analysis. We identified 2394 patients meeting our inclusion criteria-475 in the ketamine group and 1919 in the control group. Regarding burn total body surface area (TBSA) involvement, there were 1533 in the <10% group, 586 in the 11-30% group, and 281 in the >31% group. The median number of ventilator-free days within the first 30 days did not vary significantly between the ketamine group and the control group: 8.5 days (interquartile range [IQR] 1-16 days) versus 8 days (IQR 3-13 days, p = .442). Subjects receiving ketamine had higher mortality rates: 59.4% (n = 117) versus 40.6% (n = 80, p < .001), with an odds ratio for in-hospital mortality of 7.51 (95% CI 5.53-10.20, p < .001). When controlling for TBSA category, ventilator days and vasopressor administration, there was no association between ketamine and in-hospital mortality (0.66, 0.41-1.05, p = .08). When controlling for confounders, we found no difference in in-hospital mortality between the prolonged ketamine infusion recipients versus non-recipients.

Detection of IMP and VIM genes in Pseudomonas aeruginosa isolated from Egyptian patients

IntroductionMetallo-β-lactamase production among Pseudomonas aeruginosa is a major health problem worldwide. Pseudomonas aeruginosa acquire several mechanisms of resistance towards carbapenems through the production of metallo-β-lactamases, especially VIM and IMP. The problem of multi-drug-resistant Pseudomonas aeruginosa is increasing all over the world, reaching dangerous levels. The aim of this study was to detect the metallo-β-lactamases bla&lt;sub&gt;VIM&lt;/sub&gt; and bla&lt;sub&gt;IMP&lt;/sub&gt; genes in Pseudomonas aeruginosa strains in Suez Canal University Hospital in Ismailia, Egypt.Material and methodsA cross-sectional descriptive study was conducted on 65 Pseudomonas aeruginosa strains. Genotypic detection of bla&lt;sub&gt;VIM&lt;/sub&gt; and bla&lt;sub&gt;IMP&lt;/sub&gt; was reached by using polymerase chain reaction.ResultsOut of 65 Pseudomonas aeruginosa strains , bla&lt;sub&gt;VIM&lt;/sub&gt; gene was present in four females and one male, with an age of 42.9 ±18.1; two cases were isolated from the Oncology Department, and one case each was present in the Burn Unit, Surgery Ward, and Intensive Care Unit. The bla&lt;sub&gt;VIM&lt;/sub&gt; gene was expressed in four stains, while the bla&lt;sub&gt;IMP&lt;/sub&gt; gene was not expressed in any strain.ConclusionsThe carbapenem resistance in our patients can be referred to as metallo-β-lactamases bla&lt;sub&gt;VIM&lt;/sub&gt; type. The problem of metallo-β-lactamases and carbapenem resistance requires ongoing surveillance, strong preventive measures, and implementation of infection control policies and procedures. Also, routine diagnostic laboratory methods should be performed, and synthesis of antimicrobial products with new effecting mechanism should be implemented in hospitals.

The effect of scenario based teaching for critical care nurses and physicians on their knowledge of fluid creep

Introduction: Fluid resuscitation is a major component of the acute management of critically ill patients. The phenomenon of providing excessive fluid resuscitation volumes has been termed “fluid creep”. Today, the science of nursing becomes more complex. Accurate fluid balance assessment and recording is important component of nursing care that assures patient’s safety especially in critically ill patients. The aim of the work is to examine the effect of scenario based teaching for critical care nurses and physicians on their knowledge of fluid balance &amp; fluid creep.Methods: The study design: pre &amp; posttest research design. Setting: This study was implemented in general, trauma, obstetric and burn intensive care units (ICUs) at Assiut university Hospital-Assiut-Egypt. Subjects: 35 critical care nurses and 29 intensive care physicians were drawn from the previously mentioned ICUs. Methodology: A pre &amp; posttest questionnaire of nurses’ and physicians’ knowledge, perception and satisfaction regarding fluid creep and fluid balance was adapted from the articles and was used in data collection before and after the application of scenario based teaching. This questionnaire was implemented on two phases (pre and after the teaching program). The data was collected from January 2018 to July 2018.Results: There is a considerable improvement in participants’ knowledge and perception concerning fluid balance and fluid creep after applying the scenario based teaching (p value &lt; .001).Conclusions: Nowadays, nurses and physicians need advanced level of knowledge to be able to deal with the physiological changes that occur in critically ill.

Acinetobacter – the trojan horse of infection control?

Five cases of multi-resistant Acinetobacter baumanii (MRA) producing OXA-23 and OXA-51 occurred in a regional burn intensive care unit (BICU). Three were repatriated from other parts of the world (Dubai and Mumbai) and colonized on admission. Despite optimal precautions, two patients acquired MRA. Both had been nursed in the same room. Multi-disciplinary outbreak investigation of MRA in a regional BICU. The mechanism of transfer for the first case is thought to have been contaminated air from theatre activity releasing MRA bacteria into the communal corridor. No MRA patients went to theatre between the first and second acquired cases. The mechanism of transfer for the second case is thought to have been via a shower unit that was decontaminated inadequately between patients. In an outbreak where contact precautions and environmental cleaning are optimal, it is important to give careful consideration to other mechanisms of spread. If there is a failure to do this, it is likely that the true causes of transmission will not be addressed and the problem will recur. It is recommended that burn theatres within burn facilities should be designed to operate at negative pressure; this is the opposite of normal operating theatre ventilation. Where showers are used, both the shower head and the hose should be changed after a patient with a resistant organism. The role of non-contact disinfection (e.g. hydrogen peroxide dispersal) should be reconsidered, and constant vigilance should be given to any 'trojan horse' item in the room.

Impact of an Acinetobacter baumannii outbreak on kidney events in a burn unit: A targeted machine learning analysis

Multidrug-resistant (MDR) bacteria outbreaks represent a major threat in intensive care units. Patients may then be exposed to drug-related direct toxicity during such outbreaks. The objective of this study was to explore the impact of an outbreak of imipenem-resistant Acinetobacter baumannii (IR-AB) on renal outcomes. We performed a before-and-after observational study in a French burn intensive care unit during an IR-AB outbreak: a 13-month period before (period A, October 2013-October 2014) and a 13-month period after outbreak control (period B, December 2014-December 2015). A total of 409 patients were included, 195 during period A and 214 during period B. The main endpoint was major adverse kidney events at day 90 (MAKE 90). Secondary endpoints were acute kidney injury (AKI) and persistent renal dysfunction. Incidence of MAKE 90 was 15.9% during period A versus 11.2% during period B (P = .166) and AKI 28.2% versus 18.7% (P = .023). The use of colistin was associated with renal outcomes in univariate analysis. After adjustment of potential confounding factors using a targeted Machine Learning Analysis (ie, IR-AB-related infection, septic shock, severity scores, other nephrotoxics, chronic kidney disease, serum creatinine at admission, Staphylococcus aureus), colistin remained associated with the risk of MAKE and AKI (relative risk = 2.909, 95% confidence interval [CI] [1.364, 6.204], P = .006for MAKE 90, and relative risk = 2.14, 95% CI [1.52, 3.02], P<.0001 for AKI). The episode of IR-AB outbreak was associated with an increased risk of kidney events, which appears to be driven by the use of colistin.

Keep initiative mind to save burn crisis and strive hard to reach the summit of the burn discipline

The Department of Burns and Plastic Surgery in Guangzhou Red Cross Hospital of Medical College of Ji'nan University grew up along with the development of burn discipline in China. In the past 60 years, it has developed into a burn specialty with three wards, 100 beds, and nearly 100 medical staff from several beds and surgeons. It is characterized by the treatment of severe burns and is a medical burn center integrating medical treatment, teaching and scientific research. In recent ten years or more, the subject development has closely followed the changes of burn discipline and society and has carried out the construction of sub-specialties. It has formed obvious speciality features in the network construction for severe burn rescue, the construction and management of burn intensive care unit and the comprehensive prevention and treatment of multiple organ dysfunction syndrome for severe burn patients and has enjoyed a good reputation in our speciality. We will continue to maintain the professional spirit of burn medicine workers for emergency and disaster relief for burned patients, keep initiative mind, strive hard to continuously improve the professional and technical level, and strive to establish a regional burn treatment center to make more contributions to the development of burn discipline.

Experience in the clinical use of allogeneic fibroblasts in patients with severe burns

Purpose. To evaluate the results of the application of allogenic fibroblasts in patients with extensive thermal burns.&#x0D; Methods. The study included 34 patients with burns over 20% TBSA, treated in the burn ICU. In accordance with the indications for transplantation of fibroblasts, all patients were divided into 4 groups: stimulation of regeneration of superficial burns (n = 10), stimulation of regeneration after meshed skin graft (n = 14), reduction of healing time for donor wounds (n = 6) and acceleration growth of granulations after the escharectomy (n = 4).&#x0D; Results. A positive effect of fibroblast transplantation was found in 7 (70%) patients of the first group, 13 (93%) of the patients in the second group, 2 (33%) of the third group and 2 (50%) in the fourth study group.&#x0D; Conclusion. The maximum positive effect of transplantation of human dermal fibroblasts can be observed when performing the meshed skin graft and treating the superficial burns.

Using competing risk and multistate model to estimate the impact of nosocomial infection on length of stay and mortality in burn patients in Southeast China

ObjectiveDue to the defects in skin barrier function and immune response, burn patients who survive the acute phase of a burn injury are at a high risk of nosocomial infection...

Effects of obesity on burn resuscitation

The effects of obesity on resuscitation after severe burn are not well understood. Formulas to calculate 24-h resuscitation volumes incorporate body weight, which in obese patients often leads to excessive fluid administration and potential complications such as pulmonary edema, extremity or abdominal compartment syndrome, and longer mechanical ventilation. We evaluated the impact of obesity on 24-h fluid resuscitation after severe burn using a cohort of 145 adults admitted to the burn ICU from January 2014 to March 2017 with >20% total body surface area burns. Patients were divided into four groups based on body mass index: normal weight (index of <25), overweight (25–29.9), obese (30–39.9), and morbidly obese (>40). Median total body surface area burn was 39.4% (interquartile range: 23.5%–49.5%). Patients were 74.5% male and demographics and injury characteristics were similar across groups. Resuscitation volumes exceeded the predicted Parkland formula volume in the normal and overweight groups but were less than predicted in the obese and morbidly obese categories (p<0.001). No difference was found in 24-h urine output between groups (p=0.08). Increasing body mass index was not associated with increased use of renal replacement therapy. Only total body surface area burned, and age were independent predictors of hospital mortality (p<0.001). We conclude that using body weight to calculate resuscitation in obese patients results in a predicted fluid volume that is higher than the volume actually given, which can lead to over-resuscitation if rates are not titrated regularly to address fluid responsiveness.

Optimization of Laboratory Ordering Practices for Complete Blood Count With Differential.

To investigate the utilization of CBC and CBC with differential (CBC w/diff) tests at University of Alabama at Birmingham Hospital, and to determine if a reduction in CBC w/diff tests could be achieved without negatively impacting patient care. The quantity of testing and distribution of repeated tests before, during, and after an educational intervention were compared. CBC w/diff tests were ordered 10-fold more frequently than CBC tests. The trauma burn intensive care unit ordered the most CBC w/diff tests, with repeat tests done every 4 or 12 hours. The educational intervention reduced the number of CBC w/diff tests ordered and tests repeated every 12 hours. The educational intervention changed the ordering practices of CBC w/diff and CBC tests. This was sustained after the intervention and no negative effects on patient care were noted. Similar interventions may lead to optimization of ordering practices of other laboratory tests.

Study on the application of dexmedetomidine combined with remifentanil in dressing change of conscious patients with non-intubation in burn intensive care unit

Objective: To observe the analgesic and sedative effect and safety of application of dexmedetomidine combined with remifentanil in dressing change of conscious patients with non-intubation in burn intensive care unit. Methods: Forty patients conforming to the study criteria hospitalized in our burn intensive care unit from April 2015 to April 2017 were selected. Prospective, randomized, and double-blind method was used for the design. Patients were divided into dexmedetomidine group and dexmedetomidine+ remifentanil group according to the random number table, with 20 cases in each group. Patients in the two groups were respectively given corresponding drugs during dressing change. The frequency and time of dressing change, Verbal Rating Scale (VRS) score of patients during dressing change (at drug administration for 25 minutes) and after dressing change (25 min after dressing change), Ramsay Sedation Score (RSS) during dressing change, satisfaction level for anesthesia of the patients and physicians after dressing change, dosage of remifentanil, and various adverse effects during and after dressing change were recorded. The heart rate, mean arterial blood pressure (MAP), respiratory rate, and pulse oxygen saturation (SpO2) before drug administration and at 10, 15, and 25 minutes after drug administration were also recorded. Data were processed with analysis of variance for repeated measurement, t test, chi-square test, and Fisher's exact probability test. Results: (1) Totally 38 patients completed the trial. There were no statistically significant differences between patients in two groups in gender, American Association of Anesthesiologist Grading, age, weight, and total burn area (χ2=0.230, 0.146, t=0.224, 0.351, 0.367, P>0.05). (2) The frequency of dressing change of patients in two groups were both 48 times. The time of dressing change and VRS scores during dressing change of patients in two groups were similar (t=0.821, 1.522, P>0.05). The VRS score of patients in dexmedetomidine+ remifentanil group after dressing change was (3.1±0.4) points, obviously lower than (3.8±0.8) points in remifentanil group (t=2.213, P<0.05). The RSS, satisfaction level scores for anesthesia of the patients and physicians after dressing change in dexmedetomidine+ remifentanil group were (3.13±0.32), (3.44±0.41), and (3.13±0.25) points, respectively, obviously better than (1.82±0.24), (2.71±0.23), (2.53±0.41) points in remifentanil group (t=2.226, 2.684, 7.702, P<0.01). The dosage of remifentanil of patients in dexmedetomidine+ remifentanil group was (282±19) μg, obviously less than (340±31) μg in remifentanil group (t=9.896, P<0.01). There were no statistically significant differences between patients in two groups in rates of respiratory inhibition and hypotension (χ2=0.211, 0.154, P>0.05). Compared with those in remifentanil group, the rates of nausea, vomiting, and other gastrointestinal symptoms of patients in dexmedetomidine+ remifentanil group were obviously reduced (P<0.05), but the rate of bradycardia was obviously increased (χ2=6.008, P<0.05). (3) There were no statistically significant differences between patients in two groups in heart rate, MAP, respiratory frequency, and SpO2 before drug administration (t=0.444, 0.892, 1.059, 1.039, P>0.05). The heart rates of patients in dexmedetomidine+ remifentanil group at 10, 15, and 25 minutes after drug administration were (83±11), (78±10), and (82±14) times per minute, respectively, significantly lower than (95±10), (87±12), and (89±12) times per minute in remifentanil group (t=5.592, 3.992, 2.630, P<0.05 or P<0.01). The MAP of patients in dexmedetomidine+ remifentanil group at 15 and 25 minutes after drug administration were (69.4±3.1) and (73.8±2.2) mmHg (1 mmHg=0.133 kPa), respectively, significantly lower than (75.4±3.0) and (78.1±3.5) mmHg in remifentanil group (t=9.181, 7.206, P<0.01). There were no statistically significant differences between patients in two groups in respiratory frequency at each time point after drug administration (t=1.489, 1.862, 1.963, P>0.05). The SpO2 of patients in dexmedetomidine+ remifentanil group at 15 minutes after drug administration was 0.972±0.018, obviously lower than 0.979±0.015 in remifentanil group (t=2.070, P<0.05). Conclusions: Application of remifentanil with small dosage has effective analgesia for conscious burn patients with non-intubation during dressing changes, however, adverse effects such as nausea and vomiting are likely to occur. Remifentanil combined with dexmedetomidine not only guarantee the analgesic effect, but also reduce the dosage of analgesics, improve the sedative effect and satisfaction of the patients for anesthesia, and reduce various adverse effects. However, it will increase the incidence of bradycardia and has some inhibition effect on circulation at the same time.

Universal decolonization with octenidine: First experiences in a tertiary burn intensive care unit

BackgroundBurn patients are predisposed for nosocomial infections during their stay on a burn intensive care unit. Moreover, several outbreaks affecting burn units for example caused by Methicillin-resistant Staphylococcus aureus (MRSA) have been reported. One attempt to address these challenges is the use of universal decolonization. MethodsIn 2015 we implemented universal decolonization for all burn patients using the antiseptic agent octenidine for intact skin and the nasopharyngeal mucosa. We conducted a retrospective analysis to evaluate the effect of the decolonization on primary, central line (central venous catheter)-associated bloodstream infections (CLABSI), the frequency of nosocomial clusters (4 or more cases with epidemiologic link and identical molecular pattern) with multidrug-resistant bacteria (MDRB) and the incidence of MRSA. ResultsIn the decolonization period a reduction of the incidence of CLABSI, nosocomial MRSA acquisition and the frequency of nosocomial MDRB clusters was observed. The incidence rate of CLABSI decreased from 2/1000 central venous catheter days in the pre-decolonization phase to 0.8/1000 central venous catheter days in the decolonization period, although this was not statistically significant. The implementation was accompanied by several feedback talks and training for the staff. The user experience was positive and no adverse effects occurred. ConclusionOur results show that universal decolonization in burn patients using octenidine is a promising concept to address hospital acquisition of MRSA; occurrence of CLABSI as well as the spread of MDRB causing clusters. It is of high relevance to further assess the value of this measure in terms of reducing CLABSI in burn patients in larger study groups. Therefore further studies including more burn patients guaranteeing adequate sample size are needed.

Acute Kidney Injury After Burn: A Cohort Study From the Parkland Burn Intensive Care Unit.

Acute kidney injury (AKI) is a common and morbid complication in patients with severe burn. The reported incidence of AKI and mortality in this population varies widely due to inconsistent and changing definitions. They aimed to examine the incidence, severity, and hospital mortality of patients with AKI after burn using consensus criteria. This is a retrospective cohort study of adults with thermal injury admitted to the Parkland burn intensive care unit (ICU) from 2008 to 2015. One thousand forty adult patients with burn were admitted to the burn ICU. AKI was defined by KDIGO serum creatinine criteria. Primary outcome includes hospital death and secondary outcome includes length of mechanical ventilation, ICU, and hospital stay. All available serum creatinine measurements were used to determine the occurrence of AKI during the hospitalization. All relevant clinical data were collected. The median total body surface area (TBSA) of burn was 16% (IQR: 6%-29%). AKI occurred in 601 patients (58%; AKI stage 1, 60%; stage 2, 19.8%; stage 3, 10.5%; and stage 3 requiring renal replacement therapy [3-RRT], 9.7%). Patients with AKI had larger TBSA burn (median 20.5% vs 11.0%; P < .001) and more mechanical ventilation and hospitalization days than patients without AKI. The hospital death rate was higher in those with AKI vs those without AKI (19.7% vs 3.9%; P < .001) and increased by each AKI severity stage (P trend < .001). AKI severity was independently associated with hospital mortality in the small burn group (for TBSA ≤ 10%: stage 1 adjusted OR 9.3; 95% CI, 2.6-33.0; stage 2-3 OR, 35.0; 95% CI, 9.0-136.8; stage 3-RRT OR, 30.7; 95% CI, 4.2-226.4) and medium burn group (TBSA 10%-40%: stage 2-3 OR, 6.5; 95% CI, 1.9-22.1; stage 3-RRT OR, 35.1; 95% CI, 8.2-150.3). AKI was not independently associated with hospital death in the large burn group (TBSA > 40%). Urine output data were unavailable. AKI occurs frequently in patients after burn. Presence of and increasing severity of AKI are associated with increased hospital mortality. AKI appears to be independently and strongly associated with mortality in patients with TBSA ≤ 40%. Further investigation to develop risk-stratification tools tailoring this susceptible population is direly needed.

Incidence of methicillin resistant Staphylococcus aureus (MRSA) in burn intensive care unit: a systematic review.

Burn victims admitted in burn intensive care units (ICU) are at a high risk of nosocomial infections generated by methicillin resistant Staphylococcus aureus (MRSA). This systematic review aims to estimate the incidence of MRSA among burn patients admitted to the ICU setting, with an emphasis on the incidence rate and antibiotic resistance profile of the MRSA strains. A systematic literature search was performed in five electronic databases limited to publication dates from 1st January 2000 until 31st August 2017. After screening n=481 articles, n=21 were found to meet the inclusion criteria of this systematic review. Results from the meta-analysis revealed that the risk for MRSA isolates in the burn ICU was 55.0% higher (OR 0.55, 95%CI 0.32-0.94). Therefore, timely testing, appropriate hygiene practice and suggested wound care must be practiced while handling such patients. Further studies are needed to identify the risk factors of MRSA infections among burn patients and to develop new antimicrobial agents for MRSA infections.

Gender has no influence on mortality after burn injuries: A 20-year single center study with 839 patients

BackgroundAccording to the ABSI – Abbreviated Burn Severity Index – women exhibit an increased risk of succumbing to burn injuries. In contrast, following non-thermal trauma, increased mortality has been shown for the male gender. Therefore, the purpose of this study was to evaluate gender-specific differences among burn patients with special regard to burn mortality. MethodsWe retrospectively studied 839 patients who were admitted to the Burn Intensive Care Unit (BICU) and underwent surgical treatment between June 1994 and December 2014. In-hospital mortality was the main clinical endpoint. Odds ratios (ORs) were calculated using univariate and multivariate logistic regression models for the association between sex and mortality. ResultsIn total, we included 530 male and 309 female burn patients. All patients had at least partial-thickness burns and underwent one or more operative procedures. Women were significantly older than men (mean 60.0 years vs 46.2 years; p<0.001). Despite having smaller injuries (24.6% vs 30.3% total body surface area (TBSA); p<0.001), burn mortality among women significantly differed from that of men (27.8% vs 21.7%; OR 1.39, p=0.045, 95% CI 1.01–1.92). This association, however, did not persist after adjusting for age, %TBSA, inhalation injury and full-thickness burns (OR 1.07, p=0.77, 95% CI 0.68–1.70). ConclusionsDespite increasing research directed at women’s health, the assoziation between gender and burn mortality has yielded conflicting results. This study does not support a gender-specific difference in burn mortality in our study population.

The design of an estimation norm to assess nurses required for educational and non-educational hospitals using workload indicators of staffing need in Iran

BackgroundOne of the effective strategies in the fair distribution of human resources is the use of estimation norm of human workforce. A norm is a coefficient or an indicator for estimating the required human resources in an organization. Due to the changes in the available working hours of nurses in recent years and to use of a standard method, the Iranian Ministry of Health decided to update nursing estimation norm in hospitals in 2014–2015. This study aimed to design a nurse-required estimation norm for educational and non-educational hospitals based on the workload indicator in Iran.MethodsThis was a descriptive cross-sectional study, carried out from December 2015 to November 2016 in 49 wards in 12 educational and 17 non-educational hospitals in Mashhad, Iran. The wards and hospitals who had the best performance in nursing care quality indicators were selected. Focus group, work study, consensus, interview, and reviewing documents, staff and patient records, and the calculations of modified Workload Indicators of Staffing Needs (WISN) were used to collect the data.ResultsPatient care, cardiopulmonary resuscitation, and transfer out of the hospital were identified as the main activities of holding focus groups. Interviews and reviewing documents led to the identification of 10 factors associated with nurses’ available working time. In both educational and non-educational hospitals, the annual working time of all nurses except nurses working in the burn and psychiatric, burn ICU, and pediatric psychiatry wards, which was 1302 h per year, was 1411 h per year. The calculations of the modified WISN method showed that the lowest norm in educational hospitals was for psychiatric, eye surgery, and dermatology wards (0.53) and in non-educational hospitals was for ENT ward (0.57). The highest norm in educational and non-educational hospitals was for burn ICU (3.95) and general ICU (3.07) wards, respectively.ConclusionThe nursing estimation norm in different wards of the hospital varies, considering that the time available to nurses and their workload in different wards and hospitals are different, and each ward has its special norm therefore, a single norm for all wards and hospitals cannot be used for a fair distribution of nurses.

Experience of transportation of mass severe burn patients for long distance by air ambulance with fixed wing

Objective: To explore the experience of transportation of mass severe burn patients for long distance by air ambulance with fixed wing. Methods: The organization and implementation process of transportation of 5 patients in the devastating forest fire of Greater Khingan on 2nd, May 2017, for long distance by air ambulance with fixed wing were reviewed and analyzed. All the patients were severely burned and complicated with inhalation injury. Four hours after accident, the relevant authority dispatched national medical team with 2 specialists of burn, 1 specialist of intensive care medicine, 1 head nurse of burn intensive care unit (ICU) to treat and cure the patients before transportation. Three patients had tracheotomy and four patients had escharotomy. Patients and their relatives, expert group of transportation, and aircrew members were arranged according to the scheme before transportation. Patients were monitored and treated with the equipments of air ambulance during the transportation. Patients were transferred to the burn ICU in our hospital from the airport through the green channel. Results: All the five patients were transported to the destination safely for long distance of 1 700 kilometres and air flight 3.5 hours one way by air ambulance with fixed wing in 4 batches at 26 to 44 hours post burn, and transported from tarmac to burn ICU of our hospital. All the patients were in stable condition during the transportation and had successful subsequent rescue. All the patients were discharged in three months. Conclusions: It is feasible to transfer mass severe burn patients for long distance by air ambulance with fixed wing, and it is safer and more effective to transfer according to the standardization process, and the opportunity of transportation of severe burn patients can be moved up to shock stage.

How long are burn patients really NPO in the perioperative period and can we effectively correct the caloric deficit using an enteral feeding “Catch-up” protocol?

Objective“NPO at midnight” is a standard preoperative practice intended to reduce aspiration risk but can result in prolonged feeding interruptions in critically ill burn patients. Postoperative hyperalimentation in the form of a “catch-up” tube feeding protocol is routine. A retrospective review of our perioperative fasting practices and “catch-up” enteral feeding protocols was performed. MethodsPatients admitted to the Burn ICU from July 1st, 2015 to August 31st, 2016 were reviewed. Patients who had a protected airway in place, prescribed enteral nutrition, and underwent surgery were included. The time from NPO to surgical start (NPO-SS), NPO to feeding restart (NPO-FR), and calories received/prescribed were quantified. The efficacy of a postoperative catch-up feeding protocol was analyzed. ResultsThere were 41 patients that fit inclusion criteria with some undergoing multiple surgeries, yielding 109 surgeries/discrete perioperative events. The average total body surface area burn (38.1±23.6%), age (38.8±20.1years), ICU days (45.0±37.3 days), and ventilator days (35.1±33.8 days) were calculated. Average fasting durations of NPO-SS and NPO-FR were 9.3±3.1 and 14.2±4.1h, respectively. The average caloric deficit to prescribed calories ratio during the NPO-SS and NPO-FR periods were 1154±629/3534±851kcal and 1765±928/3534±851kcal, respectively. A post-operative catch-up protocol completely compensated for perioperative caloric deficits 68.8% (22/32) of the time. ConclusionsIn critically ill burn patients, a preoperative fast resulted in an average loss of greater than 50% of prescribed calories on the day of surgery. Clinicians should re-evaluate the standard practice of making preoperative patients “NPO at midnight”. An effective catch-up protocol can adequately reduce caloric deficits.

Treatment of Genital Burn Injuries: Traditional Procedures and New Techniques.

Because genital burns are rare, only limited information on treatment guidelines is available in the literature. Vital tissue should be preserved to promote spontaneous healing because reconstruction does not always lead to satisfying results. The aim of this report is to present a general overview of current, prevailing treatment for genital burns and compare this to study authors' experiences. In addition, the article describes an entirely new approach of tissue-preserving bromelain-based enzymatic debridement of genital burn wounds. This single-center study includes all patients who were treated for severe genital and perineal burn wounds at a burn intensive care unit between December 1995 and December 2016. A review of literature was performed in PubMed covering the years 1990 to 2016. A total of 149 patients were admitted with severe burns or scalding of the genitals or the perineum. As in the majority of cases reported in the current literature, most of these patients were treated conservatively. When there was demarcation of necrotic tissue, tangential excision and skin grafting were performed, and since 2015, 3 patients admitted to this facility have been treated with bromelain-based debridement followed by spontaneous healing. Certain small-scale studies in the literature describe a disproportionate number of surgical interventions. Based on this evidence, study authors support a conservative view of genital burn treatment. Enzymatic debridement allows earlier and more selective debridement, which can improve the aesthetic outcome.

Grado de implementación de las estrategias preventivas del síndrome post-UCI: estudio observacional multicéntrico en España

AimTo evaluate the degree of implementation of protocols associated with the prevention of intensive-care-unit (ICU) acquired muscle weakness, and the presence of the physiotherapist in various ICU in Spain. MethodA descriptive, cross-sectional study performed in 86 adult ICU in Spain between March and June 2017. Neurosurgical and major burns ICU were excluded. A multiple-choice survey was used that included questions on protocols for glycaemia control, sedation, pain assessment, delirium prevention, delirium management and early mobilisation. The survey was completed using a user-protected application and password. The Student's t-test or Mann-Whitney U test and Pearson's correlation or Spearman's Rho test were used for the inferential analysis. ResultsEighty-nine point five percent of the ICU had a glycaemia control protocol, with a predominating range of 110-140mg/dl. Seventy-four point four percent evaluated sedation levels, although only 36% had sedation protocols. Pain assessment was carried out on communicative patients in 73.7%, and on uncommunicative patients in only 47.5%. Only 37.2% performed daily screening to detect delirium and 31.4% of the ICU had delirium prevention protocols, 26.7% had delirium management protocols and 14% had protocols for early mobilisation. Thirty-four point nine percent requested cross consultation with the rehabilitation department. ConclusionsThe implementation of the different protocols associated with the prevention of ICU-acquired muscle weakness was high in relation to glycaemia control protocols, sedation level and pain assessment in communicative patients, and was low for early mobilisation and delirium screening and prevention. Similarly, the physiotherapist was seldom present in the ICU.
