Surgical crisis management skills training and assessment: a simulation[corrected]-based approach to enhancing operating room performance.
(41/166)
BACKGROUND: Intraoperative surgical crisis management is learned in an unstructured manner. In aviation, simulation training allows aircrews to coordinate and standardize recovery strategies. Our aim was to develop a surgical crisis simulation and evaluate its feasibility, realism, and validity of the measures used to assess performance. METHODS: Surgical trainees were exposed to a bleeding crisis in a simulated operating theater. Assessment of performance consisted of a trainee's technical ability to control the bleeding and of their team/human factors skills. This assessment was performed in a blinded manner by 2 surgeons and one human factors expert. Other measures consisted of time measures such as time to diagnose the bleeding (TD), inform team members (TT), achieve control (TC), and close the laceration (TL). Blood loss was used as a surrogate outcome measures. RESULTS: There were considerable variations within both senior (n = 10) and junior (n = 10) trainees for technical and team skills. However, while the senior trainees scored higher than the juniors for technical skills (P = 0.001), there were no differences in human factors skills. There were also significant differences between the 2 groups for TD (P = 0.01), TC (P = 0.001), and TL (0.001). The blood loss was higher in the junior group. CONCLUSIONS: We have described the development of a novel simulated setting for the training of crisis management skills and the variability in performance both in between and within the 2 groups.

Spontaneous tracheal rupture after severe coughing in a 7-year-old boy.
(42/166)
Tracheal lacerations are rare but potentially life-threatening. They are recognized sequelae of cervical or thoracic injuries or complications of endotracheal intubation. Spontaneous tracheal rupture is extremely uncommon and has not been reported in a pediatric patient. This report is the first pediatric case of a spontaneous longitudinal laceration of the posterior membranous cervical trachea, which occurred after violent coughing in a 7-year-old boy with acute tracheobronchitis. The tracheal rupture was detected early with an endoscopic examination and computed tomography. The rupture and emphysema were small, with no major complications, and disappeared with conservative management. This rare case is presented with a review of the possible mechanism, diagnosis, and treatment. (+info)
Epidemiology of lawn-mower-related injuries to children in the United States, 1990-2004.
(43/166)
OBJECTIVE: Our objective for this study was to describe the epidemiology of lawn mower-related injuries among children in the United States. METHODS: A retrospective analysis was conducted of data from children who were 20 years and younger in the National Electronic Injury Surveillance System of the United States Consumer Product Safety Commission for 1990-2004. RESULTS: There were an estimated 140700 lawn mower-related injuries to children who were 20 years and younger and treated in hospital emergency departments in the United States during the 15-year period of 1990-2004. This yielded an average of 9400 injuries annually, or 11.1 injuries per 100000 US children per year. The mean age was 10.7 (SD: 6.0) years, and 78% were boys. The leading type of lawn mower-related injury sustained by patients was a laceration (41.2%), followed by soft tissue injury (21.4%), burn (15.5%), and fracture (10.3%). The most common body region injured was the hand/finger (34.6%), followed by lower extremity (18.9%) and foot/toe (17.7%). The eyeball/face and upper extremity accounted for 10.6% and 7.4% of injuries, respectively. Burns accounted for 34.5% of injuries to the hand/finger compared with 5.5% to other body regions. Ninety-seven percent of amputation injuries occurred to the foot/toe (49.5%) and hand/finger (47.5%) compared with 3% of amputations to other body regions. Burns accounted for 41.8% of injuries among children who were < or = 5 years of age compared with 6.5% of injuries to children who were older than 5 years. Foreign body injuries accounted for 4.8% of injuries among children who were > or = 12 years of age compared with 1.6% of injuries to children who were younger than 12 years. Amputations (31.9%), lacerations (28.8%), and fractures (26.0%) accounted for almost 87% of injuries among children who were admitted or transferred to another hospital. In contrast, lacerations (42.3%), soft tissue injuries (23.3%), and burns (16.9%) predominated among children who were treated and released to home from the emergency department. Children with amputations were more likely to be admitted than children with other types of injury. CONCLUSIONS: Injuries related to lawn mowers are an important cause of pediatric morbidity. The relative consistency of the number of lawn mower-related injuries to children during the 15-year study period is evidence that current prevention strategies are inadequate. Passive protection that is provided by safer product design is the strategy with the highest likelihood of success in preventing these ongoing injuries. The lawn mower voluntary safety standard American National Standards Institute/Outdoor Power Equipment Institute B71.1-2003 should be revised to include more rigorous performance provisions regarding prevention of penetration of feet and toes under the mower and into the path of the blades, shielding of hot mower parts from access by young children, and equipping all ride-on lawn mowers with a no-mow-in-reverse default feature with location of its override switch behind the seating position of the ride-on mower operator. By locating the no-mow-in-reverse override switch behind the ride-on mower operator, the operator would be required to look behind the mower before mowing in reverse. (+info)
Escalator-related injuries among children in the United States, 1990-2002.
(44/166)
OBJECTIVE: We describe the epidemiology of escalator-related injuries among children 0 to 19 years of age in the United States, with a focus on the pediatric population that is younger than 5 years. METHODS: We conducted a retrospective analysis of data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission. Reported cases were used to project national estimates and rates of escalator-related injuries in the United States. The analysis included all patients who were 0 to 19 years of age in the National Electronic Injury Surveillance System database and were seen in an emergency department for an escalator-related injury during the 13-year period 1990-2002. RESULTS: There were an estimated 26000 escalator-related injuries among children who were 0 to 19 years of age in the United States during 1990-2002, yielding an average of 2000 of these injuries annually (rate = 2.6 per 100,000 population per year). The mean age was 6.5 years at the time of injury, and 53.4% of the patients were male. When comparing cases by 5-year age groups, children who were younger than 5 years had the highest estimated number of injuries (12000), as well as the highest annual escalator-related injury rate (4.8 per 100000). The most common mechanism of injury for all age groups was a fall, accounting for 13000 (51.0%) injuries. Entrapment accounted for 29.3% of all injuries and 36.5% of injuries among children who were younger than 5 years. Six percent (723) of injuries to children who were younger than 5 years involved a stroller, with most injuries occurring when a child fell out of the stroller while on the escalator. The most common body part injured for all ages was the leg, accounting for 27.7% of all injuries. Among children who were younger than 5 years, the hand was the most common injury site (40.6%), with hand injuries frequently occurring as a result of entrapment (72.4%). A laceration was the most common type of injury, accounting for 47.4% of escalator-related injuries. Amputations and avulsions were uncommon; however, 71.4% (595 of 833) occurred among children who were younger than 5 years. CONCLUSIONS: There was a disproportionate number of escalator-related injuries among children who were younger than 5 years. Entrapment occurred more frequently among children who were younger than 5 years than in any other age group, which may explain the increased number of hand injuries in this age group. Escalator designs that reduce the gap between the steps and sidewall or shield against access to the gap may decrease entrapment risk. Young children should be supervised properly and should not be transported in a stroller while riding on an escalator. All passengers should use caution and remain alert when riding an escalator to avoid injuries related to falls or entrapment. Additional research is needed to determine the relationship among passenger behavior, escalator design, and escalator-related injury. (+info)
Differences in the risk associated with head injury for pediatric ice skaters, roller skaters, and in-line skaters.
(45/166)
OBJECTIVE: The goals were to describe the epidemiologic features of pediatric skating-related injuries sustained from 1993 to 2003 and to compare ice skating-related injuries with roller skating--and in-line skating-related injuries. METHODS: An analysis of pediatric skating-related injury data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission was performed. RESULTS: An estimated 1 235 467 pediatric skating participants presented to hospital emergency departments with injuries between 1993 and 2003. These children had a mean age of 10.9 years (SD: 3.2 years; range: 1-18 years), and 50.0% were male. The most common mechanism of injury was a fall (83.1%). Ice skaters sustained a greater proportion of head injuries (13.3%), compared with roller skaters (4.4%) and in-line skaters (5.0%). Ice skaters also experienced a greater proportion of concussions (4.3%), compared with roller skaters (0.6%) and in-line skaters (0.8%). The proportion of facial injuries among ice skaters was greater than the proportions among roller skaters and in-line skaters. The majority of roller skating-and in-line skating-related injuries were upper-extremity fractures (53.9% and 59.7%, respectively). Children < or = 6 years of age experienced a greater proportion of head and facial injuries than did older children in each skating activity. CONCLUSIONS: The epidemiologic features of pediatric ice skating-related injuries differ from those of roller skating--and in-line skating-related injuries. Children should wear helmets during all recreational skating activities, especially ice skating, because of the risk of serious head injuries. Wrist guards should be worn to protect against the common upper-extremity fractures sustained during skating. (+info)
Fractures of the supraorbital rim: principles and management.
(46/166)
Dentists may be asked to provide consultations for patients who have sustained trauma to their facial structures. Supraorbital rim fractures, although uncommon, must be recognized and promptly referred to an oral and maxillofacial surgeon or other specialist skilled in the management of facial bone fractures. Supraorbital rim fractures commonly coexist with other craniomaxillofacial injuries, especially with fractures of the anterior table of the frontal sinus. In this article, we review the frequency, management and complications associated with the treatment of supraorbital rim fractures in adults. A series of 5 cases was reviewed; 4 of the 5 patients were male, with a mean age of 21.6 years (range 17-28 years). All injuries involved the supraorbital rim and the anterior table of the frontal sinus and occurred concurrently with other facial injuries. Treatment ranged from conservative observation to open reduction and internal fixation of the fractures. No associated perioperative or postoperative complications occurred. The follow-up ranged from 6 months to 26 years, with satisfactory subjective esthetic outcomes in all cases. (+info)
Soft tissue pediatric facial trauma: a review.
(47/166)
Facial soft tissue injuries are common in pediatric trauma patients. Early diagnosis and definitive treatment as well as good postoperative wound care are important when dealing with soft tissue injuries, such as facial nerve and parotid injuries, animal bites, avulsive skin wounds and eyelid and ear lacerations. Children heal quickly, but they also tend to develop hypertrophic scars. Proper wound management during the healing period can help to minimize the risk of adverse scar formation. Dentists may be involved in the initial assessment of these patients. Knowledge of the diagnosis and management of soft tissue trauma is useful when dealing with pediatric patients and their parents postoperatively. (+info)
Trauma at a Nigerian teaching hospital: pattern and docu-mentation of presentation.
(48/166)
BACKGROUND AND OBJECTIVES: This study is aimed at identifying the characteristics of injuries and determining the efficiency of documentation of patients' records in a tertiary hospital where there is no trauma registry. PATIENTS AND METHODS: A retrospective case record analysis was conducted of injured patients seen at the Accident and Emergency unit over a 12 month period from January to December 2003. RESULTS: A total of 1078 records of injured patients that attended the A&E were analysed. Their mean age was 31 years (range 3 months to 85 years). Laceration (n = 408) and fractures (n = 266) representing 62.5% of injuries were seen. Injuries to the lower limb occurred in 239 patients, multiple anatomical sites 224, head 224, upper limb 203, the neck 20, and the abdomen 11 patients. Trauma was due to road traffic accident in 977 patients, fall in 39, assault in 14 while burns and firearm injuries occurred in 5 and 7 patients respectively. The mean injury severity score (ISS) was 4. Severe injuries, ISS > 15 occurred in 54 patients with mean ISS of 21, and resulted from RTA in 92.6% of cases. Mortality from severe injuries occurred in 31.5% of cases while overall mortality was 2%. Most deaths were associated with multiple injuries (60.9%) and head injury (30.4%). Incomplete documentation of accident and injury data occurred frequently, from 2% of some data to 100% of others. CONCLUSIONS: Lacerations and fractures were the most common injuries. Mortality is due usually to head and multiple injuries. Research into appropriate strategies for prevention of injuries, especially RTA, is required but this must start with the establishment of institutional and regional trauma registries for complete documentation of relevant data.
