Objective To explore the application effect of preoperative intravenous injection of esketamine in patients undergoing laproscopic radical resection of colorectal cancer．Methods The clinical data of patient who underwent laparoscopic radical resection of colorectal cancer in Xiamen Hospital of Traditional Chinese Medicine from January 2024 to April 2025 were retrospectively analyzed．The patients were divided into two groups according to the random number table method：40 cases in the control group were given 5 mL saline，five minutes before operation，40 cases in the observation group were treated with 0.25 mg / kg esketamine（in 5 mL saline）five minutes before operation．The perioperative indicators，inflammatory factors，negative emotions，pain and adverse reactions were compared between two groups．Results The operation time，anesthesia time and intraoperative blood loss of the observation group were（213.54±64.22）min，（240.67±81.26）min and（141.31±45.03）mL，respectively，which were not significantly different from those of the control group（210.43±65.71）min，（244.25±81.33）min and（137.64±42.75）mL（t=0.214，0.197，0.374，all P＞0.05）．The dosage of propofol and remifentanil in the observation group were（1 075.52±134.37）mg and（1 267.18±242.26）μg，respectively，which were lower than those in the control group of （1126.64±150.21）mg and（1352.50±295.14）μg，but the difference was not statistically significant（t=1.604，1.413，P＞0.05）．The levels of tumor necrosis factor-α，interleukin-6 and C-reactive protein in the observation group at 24 h after operation were（54.52±9.64）pg / mL，（40.08±7.75）pg / mL and（30.38±6.93）mg / L，respectively，which were lower than those in the control group of （77.31±10.86）pg / ml，（56.35±9.47）pg / mL and 43.73±7.61）mg / L（t=9.926，8.409，8.203，all P＜0.05）．The scores of Anxiety and Depression Self-Rating Scale at 1 day after operation and the scores of pain visual analogue scale at 1 h，6 h，12 h and 24 h after operation were（51.92±4.41），（53.96±4.47），（3.59±1.14），（3.06±1.01），（2.89±0.91） and（2.57±0.76），respectively，which were lower than those of the control group（55.06±5.12），（57.21±5.19），（4.27±1.36），（3.68±1.18），（3.41±1.06） and（2.96±0.92）（t=2.939，3.001，2.423，2.525，2.329，2.067，P＜0.05）．However，no significant difference was observed in cough-related VAS scores between the groups at 48 h postoperatively（P＞0.05）．Adverse event rates showed no significance in two groups（P＞0.05）．Conclusions Preoperative administration of esketamine in laparoscopic colorectal cancer surgery can attenuate postoperative inflammation，decrease pain，mitigate negative emotions，without increasing the incidence of postoperative adverse reactions．

目的：探究对老年腹腔镜结直肠癌根治术中患者实施环泊酚联合瑞芬太尼后对其的苏醒质量、认知功能影响。方法：选取2025年1月-10月在我院接受腹腔镜结直肠癌根治术的50例老年患者作为研究对象，并采用随机数字表法将其分为两组。对照组25例患者，实施丙泊酚联合瑞芬太尼麻醉；观察组25例患者，采用环泊酚联合瑞芬太尼进行麻醉。对两组患者的苏醒质量（睁眼时间、拔管时间、定向力恢复、Steward评分）、术后认知功能（MMSE、MOCA.POCD发生率、MOAA/S评分）、炎症反应（IL-6, TNF-a, CRP, S100B, NSE）、疼痛控制（VAS评分、镇痛药用量）、不良反应（呼吸抑制、PONV、低血压、寒战等）与术中血流动力学（血压、心率、Sp0z、PaCO2、氧合指数）进行比较分析。结果：观察组的睁眼时间（10.55±2.11 min）、拔管时间（16.44±1.55 min）、定向力恢复时间（34.55±5.33 min）短于对照组，Steward苏醒评分（5.44±0.33 min）高于对照组（P＜0.05）。观察组术后的MMSE评分（27.44±1.22 分）、MoCA评分（28.44±1.66 分）、MOAA/S评分（3.22±0.44 分）均高于对照组，POCD发生率（16.00%）低于对照组（P＜0.05）。观察组术后IL-6（100.22±10.22 pg/mL）、TNF-α（30.22±4.44 pg/mL）、CRP（80.44±5.22 mg/L）、S100B（0.15±0.02 μg/L）、NSE水平（13.66±3.22 μg/L）均低于对照组（P＜0.05）。两组的术后VAS评分比较，统计学无差异，P＞0.05；观察组24h镇痛药物用量（80.23±20.44 mg）少于对照组（P＜0.05）。观察组术中血压、心率、Sp0z、PaCO2、氧合指数比对照组更稳定（P＜0.05）。观察组呼吸抑制、PONV、低血压、寒战的不良反应发生率（16.00%）低于对照组（44.00%）（P＜0.05）。结论：环泊酚联合瑞芬太尼麻醉方案可提高老年腹腔镜结直肠癌根治术患者的苏醒质量方面，利于患者的术后认知功能恢复，减轻其神经炎症反应，维持患者血流动力学稳定，并降低镇痛药物用量与不良反应发生率。

目的 探究新斯的明拮抗顺阿曲库铵的时机对患者腹腔镜结直肠癌根治术后肌松残留和早期肺功能的影响。方法 选取于2021年2月—2022年9月在我院行结肠癌根治手术的194例患者为研究对象,以随机数字表法将患者分为空白对照组和试验组,然后结合给予新斯的明治疗时所体现的4个成串刺激（TOF）比值将试验组患者分为试验组A（TOF≤0.1）、试验组B（0.10.8）。对比组间肌松残余情况以及肺功能情况。结果 插管前,试验组A患者TOF比值低于其他组（P<0.01）,空白对照组患者TOF比值高于其他组（P<0.01）;空白对照组分别与试验组A~E在复苏室接受观察的时间比较,差异无统计学意义（P>0.01）;试验组A患者肌松恢复指数低于其他组（P<0.01）,空白对照组患者肌松恢复指数高于其他组（P<0.01）。插管前、拔管0.5 h以及拔管24 h时,组间1秒用力呼气容积（FEV1）、用力肺活量（FVC）和FEV1/FVC比较差异无统计学意义（P>0.05）。结论 结直肠癌根治术后给予新斯的明,有助于加快肌松恢复,但不会影响复苏室停留时间与肺功能水平。

Objective To investigate the effect of timing of neostigmine antagonizing cisatracurium on residual muscle relaxation and early lung function in patients underwent laparoscopic radical resection of colorectal cancer．Methods February 2021 to September 2022,194 patients who underwent radical colon cancer surgery in our hospital were selected as the research subjects．The patients were randomly divided into a blank control group and an experimental group using a random number table method．Then,combined with the train-of-four（TOF）ratios observed during neostigmine treatment,the experimental group patients were divided into experimental group A（TOF≤0.1）,experimental group B（0.10.8）．The residual muscle relaxation and lung function between groups were compared．Results Before intubation,the TOF ratio of patients in experimental group A was lower than that of other groups（P<0.01）,while the TOF ratio of patients in the blank control group was higher than that of other groups（P<0.01）．There was no significant difference in the observation time between the blank control group and the experimental group A~E in the postanesthesia care unit（P>0.01）．The muscle relaxation recovery index of patients in experimental group A was lower than that of other groups（P<0.01）,while the muscle relaxation recovery index of patients in the blank control group was higher than that of other groups（P<0.01）．There were no significant differences in force expiratory volume in one second（FEV1）,forced Vital capacity（FVC）and FEV1/FVC between groups before intubation,0.5 h after extubation and 24 h after extubation（P>0.05）．Conclusions Administration of neostigmine after radical surgery for colorectal cancer can accelerate muscle relaxation recovery,but it will not affect the residence time of the postanesthesia care unit and lung function levels．
