Epidemiology, aetiology and knowledge, attitudes, and practices relating to burn injuries in Palestine: A community-level research.

The aim of this study was to identify the epidemiology, aetiology as well as the knowledge, attitudes, and practices relating to burn injuries in Palestine. A mixed-method approach was used. A survey was distributed to a total of 1500 households selected by randomised approach. The survey was standardised based on World Health Organisation's guidelines for conducting community surveys on injury. Additionally, there were 12 focus group discussions and 10 key informant interviews to collect rich qualitative data. In the West Bank and Gaza, 1.5% of Palestinians had experienced serious burn injuries in the 12 months. The total sample of 1500 yields a margin of error (plus/minus) = 2.5% at a 95% level of confidence and a response distribution (P = 50%) with 3% non-response rate. Of the 1500 households approached, 184 reported a total of 196 burn injuries, with 87.2% occurring inside the home: 69.4% were females and 39.3% were children. The main source of reported cause of burn was heat and flame (36%), electric current (31.6%), hot liquid (28.6%), and chemicals (2.7%). The most common first aid for burns was pouring water (74.7%). People in rural, refugee, and Bedouin settings had the highest incidence of burns. This study provides the burn prevalence rate, explanatory factors that contribute to the frequency of burns in Palestine. Making burn prevention a higher priority within the national policy is crucial.

Fatal splenic rupture following Heimlich maneuver: case report and literature review.

The most effective resuscitative procedure in choking by foreign bodies is the Heimlich maneuver, described for the first time by Henry Heimlich (1974) and recognized by the US Surgeon General (1985) as the "only method that should be used for the treatment of choking from foreign body airway obstruction." If performed correctly, this lifesaving maneuver is associated with rare complications, of which the most frequent are rib fractures and gastric or esophagus perforations. Other rare traumatic injuries such as pneumomediastinum, aortic valve cusp rupture, diaphragmatic herniation, jejunum perforation, hepatic rupture, or mesenteric laceration have been described.However, we are unaware of previous reports of splenic rupture after Heimlich maneuver. We present an interesting case of fatal hemoperitoneum due to a hilar laceration of the spleen following a correctly performed Heimlich maneuver.

Pre-hospital care and its association with clinical outcome of snakebite victims presenting at a tertiary care referral hospital in South India.

Most snakebite victims in low- and middle-income countries continue to seek many forms of first aid therapy before reaching hospital, the commonest being the application of a tourniquet. Our study looked at a prospective cohort of 382 such patients to ascertain the association of pre-hospital care with clinical outcome, and found that 60% developed complications as compared to 36% who had no pre-hospital care (p < 0.001), with 10 fatalities in the former compared to only one in the latter. Pre-hospital care remains very common and definitely increases morbidity and mortality.

Prehospital tourniquet use: An evaluation of community application and outcome.

BACKGROUND: There is substantial investment in layperson and first responder training involving tourniquet use for hemorrhage control. Little is known however about prehospital tourniquet application, field conversion, or outcomes in the civilian setting. We describe the experience of a metropolitan region with prehospital tourniquet application. METHODS: We conducted a retrospective cohort study characterizing prehospital tourniquet use treated by emergency medical services (EMS) in King County, Washington, from January 2018 to June 2019. Emergency medical services and hospital records were abstracted for demographics, injury mechanism, tourniquet details, clinical care, and outcomes. We evaluated the incidence of tourniquet application, who applied the device (EMS, law enforcement, or layperson), and subsequent course. RESULTS: A total of 168 patients received tourniquet application, an incidence of 5.1 per 100,000 person-years and 3.48 per 1,000 EMS responses for trauma. Tourniquets were applied for penetrating trauma (64%), blunt trauma (30%), and bleeding ateriovenous fistulas (7%). A subset was critically ill: 13% had systolic blood pressures of <90 mm Hg, 8% had Glasgow Coma Scale score of <13, and 3% had cardiac arrest. Among initial applications, 48% were placed by law enforcement, 33% by laypersons, and 18% by EMS. Among tourniquets applied by layperson or law enforcement (n = 137), EMS relied solely on the original tourniquet in 45% (n = 61), placed a second tourniquet in 20% (n = 28), and removed the tourniquet without replacement in 35% (n = 48). Overall, 24% required massive transfusion, 59% underwent urgent surgery, and 21% required vascular surgery. Mortality was 3% (n = 4). At hospital discharge, the tourniquet limb was fully functional in 81%, partially functional in 10%, and nonfunctional in 9%; decreased function was not attributed to tourniquet application. CONCLUSION: The high rate of application, need for urgent hospital intervention in a subset, and low incidence of apparent complication suggest that efforts to increase access and early tourniquet use can provide public health benefit. LEVEL OF EVIDENCE: Therapeutic, level IV.

A hero's woe: rotator cuff tear after performing the Heimlich manoeuvre.

The Heimlich manoeuvre is well recognised worldwide as an emergency technique to clear an obstructed airway. The potential for serious injury to the choking victim is also well reported. We report the first case of significant musculoskeletal injury suffered by a rescuer performing the Heimlich manoeuvre. He eventually made a full recovery from his injury. However, we need to be aware of the possibility of injury in the rescuer as well as the rescued.

Complications as a result of the Heimlich maneuver.

The Heimlich maneuver is a well-described emergency procedure for management of foreign body airway obstructions. Although rare, complications of the Heimlich maneuver do exist. The purpose of this report is to review the known complications of this procedure. All reported complications published in English on Medline and PubMed were reviewed. Additionally, we present a rare case of acute pancreatitis with associated pseudocyst formation after the administration of the Heimlich maneuver on a healthy 3-year-old boy. Although life saving, the Heimlich maneuver may be associated with significant complications; thus, symptomatic patients after this maneuver should be thoroughly evaluated with appropriate laboratory and radiographic studies.

Frostbite injury of the foot from portable fire extinguisher.

Frostbite burns are uncommon and their etiologies are varied. We present a case of sudden frostbite burn of the left foot caused by carbon dioxide. The circumstances of this injury and preventive measures are discussed.

Inadequate knowledge about snakebite envenoming symptoms and application of harmful first aid methods in the community in high snakebite incidence areas of Myanmar.

INTRODUCTION: Every year millions of people in developing countries suffer from snakebite, causing a large number of deaths and long term complications. Prevention and appropriate first aid could reduce the incidence and improve the health outcomes for those who suffer bites. However, many communities where snakebite is a major issue suffer from a lack of information about prevention and first aid measures that a family or community member could take to prevent severe envenoming, complications and poor outcomes. Myanmar suffers from a high burden of snakebites with a large number of deaths. As part of a health services and community development program, a community survey was conducted to identify communities' knowledge about snakebite and their sequelae, and knowledge and practice about first aid and health services use. METHOD: 4,276 rural residents of Kyaukse and Madaya townships in the Mandalay region were recruited by cluster sampling, involving random selection of 144 villages and random sampling of 30 households from each village. One adult member of each household was interviewed using a structured questionnaire. RESULTS: The incidence of snakebite was 116/100,000 people. Respondents reported 15 different types of snakes in the area, with Russell's Viper, Cobra and Green snakes as the most common. 88% of the people informed that working in the fields and forests was when most of the bites occur. A majority knew about snakebite prevention methods such as wearing long boots. However, only a few people knew about the specific symptoms caused by snakebites. Only 39% knew about the correct methods of first aid. More than 60% mentioned tourniquet as a first aid method, though this may cause significant complications such as ischaemia of the limb. 88% said that they would take a snakebite victim to a government hospital, and 58% mentioned availability of antivenom as the reason for doing this. At the same time, the majority mentioned that traditional methods existed for first aid and treatment and 25% mentioned at least one harmful traditional method as an effective measure that they might use. CONCLUSION: The community is aware of snakebites as a major public health issue and know how to prevent them. However, the high incidence of snakebites point to lack of application of preventive methods. The community recognise the need for treatment with antivenom. However, inadequate knowledge about appropriate first aid methods, and a reliance on using tourniquets require a targeted education program. Existing knowledge in communities, albeit insufficient, provides a good starting point for mass media educational campaigns.

Ludwig Angina after First Aid Treatment: Possible Etiologies and Prevention-Case Report.

Ludwig angina is a life-threatening type of soft tissue cellulitis involving 3 compartments on the floor of the mouth including the submental, sublingual, and submandibular spaces bilaterally. Prevention, early recognition, and treatment of Ludwig angina are critical because this is a clinical diagnosis with unpredictable progression. This article describes a rare case of Ludwig angina that evolved from an odontogenic infection and the specific microbiology and clinical course and discusses possible etiologies and prevention.

Traumatic dissection and rupture of the abdominal aorta as a complication of the Heimlich maneuver.

Although the Heimlich maneuver is considered the best intervention for relieving acute upper airway obstruction, several complications have been reported in the literature. These complications can occur as a result of an increase in abdominal pressure leading to a variety of well-documented visceral injuries, including the great vessels. Acute abdominal aortic thrombosis after the Heimlich maneuver is a rare but recognized event; however, to date no case of traumatic dissection and rupture of the abdominal aorta has been described. We report the first known case, to our knowledge, of a traumatic dissection and rupture of the abdominal aorta after a forcefully applied Heimlich maneuver.

The response time threshold for predicting favourable neurological outcomes in patients with bystander-witnessed out-of-hospital cardiac arrest.

OBJECTIVE: It is well established that the period of time between a call being made to emergency medical services (EMS) and the time at which the EMS arrive at the scene (i.e. the response time) affects survival outcomes in patients who experience out-of-hospital cardiac arrest (OHCA). However, the relationship between the response time and favourable neurological outcomes remains unclear. We therefore aimed to determine a response time threshold in patients with bystander-witnessed OHCA that is associated with positive neurological outcomes and to assess the relationship between the response time and neurological outcomes in patients with OHCA. METHODS: This study was a retrospective, observational analysis of data from 204,277 episodes of bystander-witnessed OHCA between 2006 and 2012 in Japan. We used classification and regression trees (CARTs) and receiver operating characteristic (ROC) curve analyses to determine the threshold of response time associated with favourable neurological outcomes (Cerebral Performance Category 1 or 2) 1 month after cardiac arrest. RESULTS: Both CARTs and ROC analyses indicated that a threshold of 6.5min was associated with improved neurological outcomes in all bystander-witnessed OHCA events of cardiac origin. Furthermore, bystander cardiopulmonary resuscitation (CPR) prolonged the threshold of response time by 1min (up to 7.5min). The adjusted odds ratio for favourable neurological outcomes in patients with OHCA who received care within ≤6.5min was 1.935 (95% confidential interval: 1.834-2.041, P<0.001). CONCLUSIONS: A response time of ≤6.5min was closely associated with favourable neurological outcomes in all bystander-witnessed patients with OHCA. Bystander CPR prolonged the response time threshold by 1min.

GOAL: To identify harmful effects caused by the stabilization of the vertebral column in a trauma victim and in trauma situations without indication for stabilization of the spine in the prehospital. METHOD: It was perform an integrative literature review guided by research questions: is there a scientific evidence of harmful effects on trauma victims caused by spinal stabilization in prehospital care? and are there situations of trauma with no indication for stabilization of the spine?. RESULTS: We have performed a Boolean search in the electronic bases Cochrane Library and Pubmed and through the EBSCOhost engine in the databases CINAHL Plus, MEDLINE, MedicLatina, SPORTDiscus, PsycARTICLES, PsycBOOKS, Psychology and Behavioral Sciences Collection, Academic Search Complete. Twelve articles were obtained and after applying the inclusion and exclusion criteria, the sample was five articles. CONCLUSIONS: Harmful effects of spinal stabilization on the victim of trauma related to airway management, pain, discomfort and pressure injuries are described. Situations of penetrating trauma with unstable circulation and victims with gunshot injuries to the head do not require stabilization of the spine. Recommendations to support the prehospital decision regarding stabilization of the spine were collected.It is crucial for the improvement of prehospital care to integrate an individualized approach of the victim that refers to its clinical state and mechanism of injury

An interesting complication of the Heimlich manoeuvre.

The removal of inhaled foreign bodies using the Heimlich manoeuvre is recommended as part of the immediate management of the choking child. We report on a case of witnessed laryngeal obstruction by a foreign body in which repeated Heimlich manoeuvres failed to expel the foreign body, but temporarily relieved the obstruction. The repeated Heimlich manoeuvres dislodged the foreign body into the trachea and may have contributed to the rapid development of extensive surgical emphysema, pneumomediastinum and pneumopericardium. The purpose of this report is to demonstrate that the Heimlich manoeuvre was effective in relieving the airway obstruction, but was associated with potentially severe complications.

Artificial ventilation for basic life support leads to hyperventilation in first aid providers.

The 'Guidelines 2000 for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care - International Consensus on Science' recommend an artificial ventilation volume of 10 ml/kg bodyweight (equivalent to a tidal volume of 700-1000 ml) without the use of supplemental oxygen in adults with respiratory arrest. For first aid providers using the mouth-to-mouth or mouth-to-nose-ventilation technique, respectively, a ventilation volume of approximately 9.6 l/min results. Additionally, a deep breath is recommended before each ventilation to increase the end-expiratory oxygen concentration of the air exhaled by the first aid provider. To investigate the effects of these recommendations in healthy volunteers, test persons were asked to ventilate an artificial lung model for a period of up to 10 min. The tidal volume was set at 800 ml at a breathing rate of 12/min. End-tidal carbon dioxide, oxygen saturation (measured by pulse oximetry), and heart rate were measured continuously. Capillary blood gas samples were collected and non-invasive blood pressure readings were recorded prior to the start of ventilation and immediately after the end of the measuring period. The data reveal a statistically significant and clinically relevant decrease in end-tidal carbon dioxide pressure (P<0.001, median decrease 14 mmHg), and the occurrence of hyperventilation-associated symptoms such as paraesthesia, dizziness, and carpopedal spasms in more than 75% of the participants. Clinically and statistically significant hyperventilation results in first aid providers performing artificial ventilation according to the guidelines. This artificial ventilation is associated with a significant decrease in capillary and end-tidal carbon dioxide pressure as well as with multiple symptoms of an acute hyperventilation syndrome. Ventilation performed according to these guidelines may cause injury to the health of the first aid provider. Rescuers ventilating the victim should be replaced at regular intervals and the recommendation to take a deep breath before each ventilation should not be upheld in order to minimise the risk of hyperventilation.

Rupture of the lesser gastric curvature after a Heimlich maneuver.

BACKGROUND: We present a case of lesser gastric curvature injury after a Heimlich maneuver due to obstruction of the breathing tract that was repaired by laparoscopic surgery. METHODS: A patient with perforation of the lesser gastric curvature as a result of closed abdominal traumatism was operated on using the laparoscopic approach with the use of four trocars as work openings. With this technique, the diagnosis was confirmed, the injury repaired, and the abdominal cavity washed. RESULTS: The postoperative period was favorable and the patient was released from the hospital on day 7 without any complications. CONCLUSIONS: Laparoscopic surgery can be technically reproduced in the treatment of gastric injury as a result of closed abdominal traumatism.

Gastric rupture after Heimlich maneuver and cardiopulmonary resuscitation.

Choking is a common emergency problem. The Heimlich maneuver is unquestionably effective in relieving airway obstruction. Serious and life-threatening complications may arise, however, if the maneuver is applied incorrectly. Two cases of gastric rupture after Heimlich maneuver are reported. Lay public, paramedics and the medical professionals should be educated with the correct technique of Heimlich maneuver and its potential complications. All patients receiving Heimlich maneuver should be examined by an experienced physician.

Burn wounds infected by contaminated water: case reports, review of the literature and recommendations for treatment.

First-aid education for the management of burns advocates cool running water over burnt skin to limit soft tissue damage. However, the water used may itself constitute a risk. We report three cases of severe invasive and necrotizing infection in patients who used or immersed themselves in contaminated water in an attempt to extinguish the fire following acute major burns. Wound cultures from all patients yielded Aeromonas hydrophila and two yielded Bacillus cereus. One patient had a complex polymicrobial infection, including zygomycosis with Rhizomucor variabilis. All patients were treated aggressively with wound débridement, including one patient who required bilateral lower limb amputations to control progressive infection. All infections were successfully treated and all patients survived their burn injuries. We review the management of burns complicated by exposure to contaminated water leading to burn wound infections. We describe commonly reported organisms from various water sources, the appropriate initial empirical antimicrobial chemotherapy and present the clinician with a proposed algorithm for managing these serious infections.
