本文报导了对15例重度烧伤合并肺功能不全患者行高频通气辅助治疗。通气期间和未通气期间各30次配对血气分析,结果表明高频通气能有效地提高动脉血氧分压。建议对烧伤合并肺功能不全患者,宜早期给予高频通气辅助呼吸。
Since 1982, 39 cases suffering from severe burns with acute pulmonary insufficiency were treated by high frequency ventilation (HFV). Blood gas changes were observed in 15 cases with mean burn areas of 67.7% TBSA, among them, 10 cases complicated with inhalation injury. The indieations for HFV treatment are: dyspnea, increase of respiratory rate (>30times/min.), and PaO_2<60mmHg (8.00 KPa). Results: 30 times of blood gas analysis were studied with or without HFV in 15 cases. The mean PaO_2 value was 59.2 mmHg (7.89 KPa) without HFV, while the mean PaO_2 value was 109.3 mmHg (14.57KPa) with HFV. The difference was significant (P<0.01). Their results showed that HFV can improve ventilation and raise PaO_2 value in severe burned patients with acute pulmonary insufficiency. The mean PaCO_2 values were 33.6mmHg (4.48 KPa) and 32.9mmHg (4.39 KPa) respectively without HFV and with HFV, no significant difference was found(P>0.05). There was no retention of CO_2 in blood when HFV was used. The advantages of HFV were discussed in this paper. This study suggests that it is advisable to use HFV in severely burned patients with acute pulmonary insufficiency.
