目的 分析艾司氯胺酮对剖宫产术后镇痛及肾素-血管紧张素-醛固酮系统（RAAS）、产后抑郁情况发生的影响。方法 研究对象为2020年5月—2021年6月在我院行剖宫产的96例孕产妇,根据麻醉药物的不同分为研究组50例和对照组46例,2组孕产妇均给予腰硬联合麻醉行剖宫产术,研究组于手术切皮前5 min静脉注射艾司氯胺酮0.2 mg/kg,对照组静脉注射等量生理盐水。比较2组孕产妇术后疼痛评分（VAS评分）、肾素活性（PRA）、血管紧张素-II（AT-II）、醛固酮（ALD）、爱丁堡产后抑郁量表（EPDS）、不良反应的发生情况。结果 与对照组比较,术后各时间点研究组孕产妇VAS评分均明显较低,差异具有统计学意义（P<0.01）。2组T1、T2、T3各时间点RAAS各指标均明显低于T0时间点（P<0.05）;研究组在T1、T2时间点RAAS各指标均明显低于对照组,差异具有统计学意义（P<0.05）。研究组术后3 d、术后6周EPDS评分均明显低于对照组（P<0.01）。2组不良反应总发生率比较无差异（P>0.05）。结论 艾司氯胺酮用于剖宫产术后镇痛效果显著,对产妇RAAS影响较小,并可缓解产妇抑郁症状,且不良反应发生率较低。

Objective To analyze the effect of esketamine on analgesia and renin angiotensin aldosterone system（RAAS）and the occurrence of postpartum depression after cesarean delivery．Methods The subjects were 96 pregnant women who underwent cesarean section in our hospital from May 2020 to June 2021,they were divided into 50 cases in the study group and 46 cases in the control group．Both groups of pregnant women were given combined spinal epidural anesthesia for cesarean section．The patients in study group were injected with esmketamine 0.2 mg/kg intravenously 5 minutes before skin incision,and those in control group were injected with the same amount of saline intravenously．The postoperative pain scores（VAS score）,plasma renin activity（PRA）,angiotensin-II（AT-II）,aldosterone（ALD）,Edinburgh Postpartum Depression Scale（EPDS）,and the occurrence of adverse effects were compared between the two groups．Results Compared with the control group,maternal VAS scores were significantly lower in the study group at all postoperative time points,and the differences were statistically significant（P<0.01）．The indexes of RAAS were significantly lower in both groups at T1,T2 and T3 time points than at T0 time point（P<0.05）;the indexes of RAAS were significantly lower in the study group at T1 and T2 time points than in the control group,and the differences were statistically significant（P<0.05）．The postoperative EPDS scores in the study group were significantly lower than those in the control group at 3 d and 6 weeks（P<0.01）．There was no difference in the overall incidence of adverse reactions between the two groups（P>0.05）．Conclusions Esketamine is effective for postoperative analgesia after cesarean section,with less effect on maternal RAAS,and can relieve maternal depressive symptoms,and has a low incidence of adverse reactions．

目的 了解颈内动脉超声联合经颅多普勒对产后抑郁症患者的检测效果,为临床产后抑制治疗提供有价值的线索。方法 收集本院于2018年3月—2020年2月收治的78例符合抑郁障碍诊断标准的产妇资料,对资料予以回顾研究,并设为研究组,同时另择选78例健康产妇为对照组,应用颈内动脉超声对两组产妇的颈动脉血流参数[颈动脉内径(D)、收缩期峰值流速(PSV)、舒张末期流速(EDV)以及阻力指数(RI)]进行检测,同时联合经颅多普勒超声(TCD)对两组产妇的左右大脑中(MCA)、脑前(ACA)及脑后(PCA)的动脉与椎基底动脉(VA-BA)血流速度进行监测,并分析两组产妇阻力指数(RI)与搏动指数(PI)变化,对以上数据统计分析并给予组间比较分析。结果 与对照组比较,研究组D、EDV水平明显下降,而RI值升高,差异有统计学意义(P＜0.05);两组产妇的PSV比较,差异无统计学意义(P＞0.05);研究组抑郁产妇的左右大脑中(MCA)、脑前(ACA)及脑后(PCA)的动脉血流速度均加快且差异均有统计学意义(P均＜0.05);研究组抑郁产妇的椎基底动脉(VA-BA)血流速度与对照组比较减慢,差异有统计学意义(P＜0.05);研究组抑郁产妇的阻力指数(RI)与搏动指数(PI)值与对照组比较,差异均无统计学意义(P＞0.05);78例抑郁产妇中,62例呈现脑动脉血流异常。检测异常率为79.49%(62/78)。结论 经颅多普勒检测,可见产后抑郁产妇的3条脑动脉血流速度明显加快,而椎基底动脉血流减缓,由此提示抑郁产妇脑动脉痉挛且脑供血明显不足,颈内动脉超声显示抑郁产妇的颈动脉血流参数有一定变化,能够为产后抑郁患者的治疗提供一定参考。

Objective To understand the detection effect of internal carotid artery ultrasound combined with transcranial Doppler on patients with postpartum depression, and to provide valuable clues for clinical postpartum depression treatment. Methods The data of 78 parturients who met the diagnostic criteria for depression in our hospital from March 2018 to February 2020 were collected. The data were reviewed and set as the study group. At the same time, 78 healthy parturients were selected as the control group.We used internal carotid artery ultrasound to detect the carotid blood flow parameters [carotid artery diameter (D), peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI)] of the two groups of parturients, and combined transcranial color Doppler ultrasound (TCD) to monitor the blood flow velocity of the arteries and vertebrobasilar artery (VA-BA), middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) of the two groups of women. The changes in maternal RI and PI between the two groups were analyzed, and the above data were statistically analyzed and compared between groups. Results Compared with the control group, the D and EDV levels of the study group were decreased, while the RI value was increased, the difference was statistically significant (P<0.05). The comparison of PSV between the two groups was not statistically significant (P>0.05). The arterial blood flow velocity in MCA, ACA, and PCA of the depressed women in the study group were accelerated and the differences were statistically significant (P<0.05). The blood flow velocity of VA-BA of the depressed women in the study group was slower than that of the control group, and the difference was statistically significant (P＜0.05). RI and PI values of depressed women in the study group were compared with those of the control group. There was no statistically significant difference between the groups (P>0.05). Among 78 depressed women, 62 had abnormal cerebral artery blood flow. The abnormal detection rate was 79.49% (62/78). Conclusion Transcranial Doppler examination showed that the blood flow of the three cerebral arteries of the postpartum depressed women was increased, while the blood flow of the vertebrobasilar arteries slowed down, which indicated that the depressed women had cerebral artery spasm and the cerebral blood supply was obviously insufficient. The internal carotid artery ultrasound showed there were certain changes in carotid blood flow parameters of depressed mothers, which can provide a certain reference for the treatment of patients with postpartum depression.
