A novel causative factor of injury: Severe burns related to fires and explosions of lithium-ion batteries of electric motorcycles.

Severe burns related to fires and explosions of lithium-ion batteries of electric motorcycles have not been reported to date. We retrospectively studied 419 patients admitted to our burn intensive care unit from January 2016 to December 2021. Of these 419 patients, 26 (22 male, 4 female; median age, 42 years) had burns related to lithium-ion battery fires and explosions, and all of their injury characteristics were similar to those of traditional flame burns. Lithium-ion battery-related burns were the eighth most common cause of burn injuries among all hospitalized patients. The 26 patients comprised 10 unemployed and 16 employed individuals. Twenty-three patients were injured at home during the battery charging process, and three were injured outdoors (one by a fire while the electric motorcycle was stationary and the others two by a fire while riding the motorcycle). The burn sites were distributed over the whole body; the burn area ranged from 10 % to 100 % of the total body surface area, and the burn depth ranged from superficial second-degree burns to third-degree burns. Twenty-three patients had inhalation injuries, and ten underwent prophylactic tracheostomy and intubation. Multiple operations were required for wound repair. Although convenient, lithium-ion electric motorcycles can also cause severe burns. To prevent these injuries, we must increase public safety awareness and education, develop new battery energy storage systems and battery management systems, and ensure the safety of batteries. Consumers should be aware of the potential dangers of lithium-ion batteries and comply with related security measures.

[Characteristics of the confined space accident and its medical rescue strategy].

OBJECTIVE: To investigate the characteristics of the confined space accident and its medical rescue strategy. METHODS: Thirty-six patients with emergency rescue in the five confined space accident during June 2009 to July 2012 were retrospectively analyzed. RESULTS: Twenty-nine people were caught in four confined space accidents caused by building collapse and 7 people were caught in one confined space accident caused by a tower of babel blast furnace damage which caused severe gas and hydrogen sulfide poisoning. For the 36 wounded, the shortest rescue time was 1.5 hours and the longest was 10.5 hours. Fourteen people were killed (mortality rate 38.89%). Characteristics of the confined space accident: the wounded activity environment was very harsh, the wounded were restricted particularly, the wounded injuries were diverse, the psychological depression was very common. The confined space environment and the complexity of wounded disease determined its medical rescue specificity and were very different from the usual trauma emergency. CONCLUSIONS: Confined space accident caused very painful casualties. The key reason is that the relevant personnel failed to clearly recognize the potential risks in the confined space or nearby, making the confined space into another "quiet killer". This problem needs to be paid highly attention.

[Observation on 27 elderly women in britain with lymphedema syndrome treated by acupuncture combined with medicine].

OBJECTIVE: To observe clinical effect of acupuncture combined with medicine therapy for elderly women in Britain with lymphedema syndrome. METHODS: Twenty-seven cases were classified according to syndrome differentiation of TCM into cold congealing and dampness obstruction type (11 cases), qi-blood stagnation type (12 cases) and downward attack of damp-heat type (4 cases). They were treated with acupuncture at main points Zusanli (ST 36), Yanglingquan (GB 34), Yinglingquan (SP 9), Sanyinjiao (SP 6), Taichong (LR 3), Fenglong (ST 40), Xuehai (SP 10), Fengshi (GB 31), Futu (ST 32), Liangqiu (ST 34), Weizhong (BL 40), etc., twice each week and oral administration of modified Duhuojisheng Decoction, Huangqiwuwu Decoction and Simiao San Decoction, respectively, meanwhile washing the affected limb with again decoction of remaining gruffs one medicament each day. They were treated for 12 weeks. RESULTS: Twelve cases were clinically cured, accounting for 44.4%, 14 cases were effective, accounting for 51.9%; and 1 case was ineffective, accounting for 3.7%. CONCLUSION: Acupuncture combined with medicine has a good therapeutic effect on lymphedema syndrome.
