The objective of this study was to present data that showed high frequency percussive ventilation (HFPV) was superior to traditional mechanical ventilation for the treatment of children with inhalation injuries. Inhalation injuries continue to be the number one cause of death of patients with thermal injuries in the United States. Therapy for this condition has consisted of conservative pulmonary toilet and mechanical ventilation. Despite improvements in the management of burn injury, patients with inhalation injury develop pneumonia and pneumothorax, leading to adult respiratory distress syndrome. Unfortunately, inhalation injury that is complicated by pneumonia has been shown to increase mortality by 60% in these patients. Cioffi has shown that prophylactic use of HFPV in adult patients with inhalation injury has been a successful method of reducing the incidence of pneumonia and mortality. The effects of HFPV on the incidence of pneumonia, peak inspiratory pressures, and arterial partial pressure of oxygen/fraction of inspired concentration of oxygen (P/F) ratios were retrospectively studied in 13 children with inhalation injuries and compared with historic controls treated with conventional mechanical ventilation. All patients were treated with our standard inhalation injury protocol and extubated when they met standard extubation criteria. Patients ranged in age from 6 to 9 years, and most had burns covering greater than 50% of their total body surface areas. No deaths occurred in either group, but the patients who were treated with HFPV had no cases of pneumonia (P < .05), better P/F ratios (P < .05), lower peak inspiratory pressures, and less work of breathing (P < .05) as compared with our control group. On the basis of our clinical experience and data, the use of HFPV seems to be an effective treatment for the reduction of pulmonary morbidity in pediatric patients with inhalation injuries.
本研究的目的是提供数据,表明高频振荡通气(HFPV)在治疗吸入性损伤儿童方面优于传统机械通气。在美国,吸入性损伤仍然是热烧伤患者的首要死因。针对这种情况的治疗包括保守的肺部清洁和机械通气。尽管烧伤治疗有所改进,但吸入性损伤患者仍会发生肺炎和气胸,进而导致成人呼吸窘迫综合征。不幸的是,合并肺炎的吸入性损伤已被证明会使这些患者的死亡率增加60%。乔菲表明,在成年吸入性损伤患者中预防性使用HFPV是降低肺炎发病率和死亡率的成功方法。对13例吸入性损伤儿童回顾性研究了HFPV对肺炎发病率、吸气峰压以及动脉血氧分压/吸入氧浓度比(P/F)的影响,并与接受传统机械通气治疗的历史对照进行比较。所有患者均按照我们的标准吸入性损伤方案进行治疗,达到标准拔管标准时即行拔管。患者年龄在6至9岁之间,大多数患者烧伤面积超过全身表面积的50%。两组均无死亡病例,但与我们的对照组相比,接受HFPV治疗的患者无肺炎病例(P<0.05),P/F比值更好(P<0.05),吸气峰压更低,呼吸功更小(P<0.05)。根据我们的临床经验和数据,使用HFPV似乎是降低小儿吸入性损伤患者肺部发病率的有效治疗方法。
