不同肠内营养时机对重型颅脑损伤患者术后并发感染的影响

目的：探讨不同肠内营养时机对重型颅脑损伤患者术后并发感染的影响。方法选择2014年5月至2015年12月期间我院重症监护室收治的56例重型颅脑损伤患者，将30例在术后24 h内开始肠内营养者纳入早期组，26例在24 h后开始肠内营养者纳入延迟组，比较两组患者术后感染并发症的情况。结果早期组术后感染总发生率为43.3%(13/30)，与延迟组的46.2%(12/26)比较差异无统计学意义(P>0.05)；但是早期组感染时间为(6.5±1.9) d，明显短于延迟组的(8.1±2.2) d，差异有统计学意义(P<0.05)。结论不同肠内营养支持时机对感染并发症的发生率影响较小，但是早期肠内营养者感染持续的时间短。

Effect of different enteral nutrition timing on postoperative infection in patients with severe craniocerebral injury

Objective To investigate the effect of different enteral nutrition timing on postoperative infection in patients with severe craniocerebral injury. Methods Fifty-six patients with severe craniocerebral injury in Intensive Care Unit in our hospital from May 2014 to December 2015 were selected. The patients were divided into two groups:30 patients started enteral nutrition within 24 h after operation were included into early group, and 26 patients started en-teral nutrition timing after 24 h were included into the delayed group. The complications of postoperative infection were compared between the two groups. Results There was no significant difference in the incidence of postoperative infec-tion in the early group and delayed group, 43.3% (13/30) vs 46.2% (12/26), P>0.05. But infection time in early group was (6.5±1.9) d, which was significantly shorter than that in delayed group of (8.1±2.2) d, and the difference was statisti-cally significant (P<0.05). Conclusion Different enteral nutrition timing has little effect on the incidence of infectious complications , but early enteral nutrition can shorten the duration of infection.
