Statins improve overall outcomes after noncardiac surgery. The primary aim of the study was to determine whether use of perioperative atorvastatin reduced the rate of postoperative complications in patients undergoing pulmonary resection.
This was a prospective, randomized, placebo-controlled, double-blind trial of patients undergoing elective pulmonary resection who received atorvastatin (40 mg daily) or placebo beginning 1 week before surgery and continued for 1 week postoperatively. Patient characteristics and postoperative complications were recorded. Plasma inflammatory markers were sampled at baseline, in the post-anesthesia care unit, and on postoperative day 3. Because of difficulty enrolling statin-naive patients, the study was stopped at the interim analysis.
Postoperative complications occurred in 16 of 72 patients (22%) receiving placebo and in 8 of 65 patients (12%) receiving atorvastatin (P = .13). For patients undergoing major anatomic resection, there were 24 complications in 15 of 45 placebo-treated patients and 8 complications in 7 of 43 atorvastatin-treated patients (P = .04). Plasma levels of C-reactive protein, tumor necrosis factor-α, and myeloperoxidase did not differ between the 2 treatment arms during the study.
After a 2-week perioperative course of atorvastatin (40 mg) in statin-naïve patients undergoing major pulmonary resection, we found evidence of a reduction in the number of clinically important cardiovascular and pulmonary complications compared with placebo. These promising results merit evaluation in a larger, perhaps multicenter study.
他汀类药物可改善非心脏手术后的总体预后。本研究的主要目的是确定围手术期使用阿托伐他汀是否能降低肺切除患者的术后并发症发生率。
这是一项前瞻性、随机、安慰剂对照、双盲试验,纳入择期肺切除患者,术前1周开始接受阿托伐他汀(每日40毫克)或安慰剂治疗,并持续至术后1周。记录患者特征和术后并发症情况。在基线、麻醉后护理单元及术后第3天采集血浆炎症标志物样本。由于难以招募未服用过他汀类药物的患者,该研究在中期分析时停止。
接受安慰剂治疗的72例患者中有16例(22%)发生术后并发症,接受阿托伐他汀治疗的65例患者中有8例(12%)发生术后并发症(P = 0.13)。对于接受主要解剖性切除的患者,45例接受安慰剂治疗的患者中有15例出现24例并发症,43例接受阿托伐他汀治疗的患者中有7例出现8例并发症(P = 0.04)。在研究期间,两个治疗组的血浆C反应蛋白、肿瘤坏死因子-α和髓过氧化物酶水平无差异。
在未服用过他汀类药物且接受主要肺切除的患者中,进行为期2周的围手术期阿托伐他汀(40毫克)治疗后,我们发现与安慰剂相比,临床上重要的心血管和肺部并发症数量有所减少。这些有前景的结果值得在更大规模、可能是多中心的研究中进行评估。
