| 目的允许性高碳酸(PHC)对肺叶切除术老年患者炎症刺激和认知功能的影响。 方法选择肺叶切除术老年患者120例,随机均分为允许性高碳酸组[PHC组,二氧化碳分压(PCO2)45~55 mmHg]和对照组(PCO2 35~45 mmHg)。记录手术期间平均动脉压、心率。ELISA检测术前、手术5 min、手术结束及术后24 h两组血肾上腺素、皮质醇及肿瘤坏死因子-α(TNF-α)水平。比较两组术前和术后7天简易精神状态检查量表(MMSE)评分和术后7天认知障碍(POCD)发生率。 结果两组手术期间心率、平均动脉压比较差异无显著性(P＞0.05)。与术前比较,两组术后7天MMSE评分均下降,但PHC组术后第7天MMSE评分高于对照组；术后7天POCD发生率PHC组低于对照组(P＜0.05)。术后24 h PHC组皮质醇、肾上腺素、TNF-α水平,以及手术结束时肾上腺素水平均低于同时间对照组(P＜0.05)。 结论PHC可有效预防老年肺叶切除术后认知功能障碍,可能与PHC降低手术引起的应激反应和炎症反应有关。 |

| AimTo explore the effects of permissive hypercapnia (PHC) on inflammatory stress and cognitive function in elderly patients undergoing pulmonary lobectomy. MethodsOne hundred and twenty elderly patients undergoing lobectomy were selected, and randomly assigned into PHC group [partial pressure of carbon dioxide (PCO2) ranging from 45 to 55 mmHg] and control group (PCO2 ranging from 35 to 45 mmHg), each with 60 cases. The mean arterial blood pressure and heart rate were recorded during surgery. Serum concentrations of adrenaline, cortisol and tumor necrosis factor α (TNF-α) were measured by using ELISH at the baseline, 5 minutes after anaesthesia induction, end of surgery and 24 h after surgery. The mini-mental state examination (MMSE) score at baseline and 7 days after surgery, as well as the incidence rate of postoperative cognitive dysfunction (POCD) at postoperative 7 days, were compared between two groups. ResultsNo statistical difference was observed between two groups in mean arterial blood pressure and heart rate during operation (P＞0.05). A reduction in MMSE score was observed in both groups, and PHC group scored higher on MMSE than control group at 7-daypost-operation. The incidence rate of POCD at 7-day post operation was lower in PHC group than in control group (P＜0.05). Serum concentrations of adrenaline, cortisol and TNF-α at 24h post-operation as well as cortisol concentration at the end of surgery were all lower in PHC group than in control group (P＜0.05). ConclusionPHC can effectively prevent cognitive dysfunction after pulmonary lobectomy in the elderly, which may be related with the alleviation in stress and inflammatoryresponse. |
