目的探究俯卧位肺复张在重症肺部感染低氧血症临床治疗中应用价值。方法 64例重症肺部感染低氧血症患者,依据治疗方法不同分为仰卧组(仰卧位肺复张治疗)与俯卧组(俯卧位肺复张治疗),各32例。观察记录两组患者治疗前后心率、血氧饱和度、平均动脉压、肺内分流、氧合指数及并发症发生率。结果治疗后,俯卧组血氧饱和度(99.5±0.7)%高于仰卧组(93.2±2.5)%,俯卧组氧合指数(390.6±46.1)mm Hg(1 mm Hg=0.133 k Pa)高于仰卧组(325.4±59.1)mm Hg,差异有统计学意义(P<0.05);俯卧组肺内分流、心率及平均动脉压与仰卧组比较,差异无统计学意义(P>0.05)。俯卧组并发症发生率为3.1%(1/32);仰卧组并发症发生率为15.6%(5/32),差异无统计学意义(P>0.05)。结论对重症肺部感染低氧血症患者予以俯卧位肺复张治疗,可有效改善患者血氧饱和度及血氧水平,且安全性较高,在临床治疗中具有重要意义。
Objective To investigate the clinical value of prone position pulmonary reexpansion in the treatment of severe pulmonary infection with hypoxemia. Methods Sixty-four patients with severe pulmonary infection of hypoxemia were divided into supine group (supine rehospitalization) and prone group (recumbent pulmonary reexpansion) according to the different treatment methods, each of 32 patients. The heart rate, oxygen saturation, mean arterial pressure, intrapulmonary shunt, oxygenation index and incidence of complications before and after treatment were recorded and recorded in both groups. Results After treatment, the oxygen saturation of the prone group (99.5 ± 0.7%) was higher than that of the supine group (93.2 ± 2.5%), and the proneness group’s oxygenation index (390.6 ± 46.1) mm Hg (1 mm Hg = 0.133 kPa) Supine group (325.4 ± 59.1) mm Hg, the difference was statistically significant (P <0.05); prone lung group shunt, heart rate and mean arterial pressure compared with the supine group, the difference was not statistically significant (P> 0.05). The incidence of complication in prone group was 3.1% (1/32). The complication rate in supine group was 15.6% (5/32), with no significant difference (P> 0.05). Conclusions Pulmonary reextensive treatment of patients with severe pulmonary infection of hypoxemia in prone position can effectively improve the oxygen saturation and blood oxygen level of patients with high safety, which is of great significance in clinical treatment.
