Objective : To investigate the effect of lidocaine combined with esketamine on recovery quality and cognitive function in patients undergoing lung surgery. Methods : A total of 100 patients receiving pulmonary resection at our hospital between July 2023 and December 2025 were enrolled and randomized via a random number table into two equal arms (n=50 per group): observation and control. The control group was treated with routine anesthesia to maintain anesthesia, and the observation group was treated with lidocaine and esketamine on the basis of routine anesthesia. The recovery quality [ Riker sedation agitation score ( SAS ) at 30 min after extubation, recovery time, extubation time ], cognitive function [ simple mental state examination score ( MMSE ) before operation and 1 d, 3 d after operation ], perioperative hemodynamic indexes [ mean arterial pressure ( MAP ), heart rate ( HR ) before anesthesia drug infusion ( T0 ), tracheal intubation ( T1 ), 5 min after extubation ( T2 ) ] and the incidence of adverse reactions at 72 h after operation were compared between the two groups. Results : In the observation group, the SAS score measured 30 minutes post-extubation and the MMSE scores at 1 day and 3 days post-operation were significantly higher than those in the control group. Conversely, both recovery and extubation times were shorter in the observation group compared to the control group. No significant differences in MAP and HR were observed at T0, T1, and T2 within the observation group (P > 0.05). In contrast, within the control group, MAP and HR at T1 and T2 were notably elevated compared to T0, with the differences being statistically significant (P < 0.05). Conclusion : The application of lidocaine combined with esketamine in lung surgery can improve the quality of recovery, protect postoperative cognitive function, maintain perioperative hemodynamic stability, and has good safety.

【摘要】目的：基于潜类别增长模型（LCGM）探讨脑出血患者神经功能恢复轨迹及不同轨迹对预后的影响。方法：回顾性采集360例自发性脑出血患者（2023年6月～2025年6月）的临床资料及神经功能评分[美国国立卫生研究院卒中量表（NIHSS）]，并采用LCGM识别神经功能恢复轨迹的潜在类别，分析影响恢复不良型轨迹的危险因素，对比不同轨迹的预后情况[改良Rankin量表（mRS）、格拉斯哥预后评分（GOS）]。结果：LCGM模型拟合结果显示，3类轨迹为最优拟合模型，可将360例自发性脑出血患者分为快速恢复型139例（38.61%）、稳定恢复型154例（42.78%）、恢复不良型67例（18.61%）；入院格拉斯哥昏迷量表（GCS）评分、初始NIHSS评分、机械通气、血管活性药物使用及血肿体积是神经功能恢复不良的独立影响因素（P＜0.05）；预后方面，三组患者mRS、GOS评分存在显著差异（P＜0.05）。结论：基于LCGM可有效识别脑出血患者神经功能恢复的异质性轨迹，同时还能明确影响患者神经功能修复的独立危险因素及不同神经功能恢复轨迹与预后的关联。

Abstract Objective: To explore the trajectory of neurological recovery in patients with cerebral hemorrhage and the impact of different trajectories on prognosis based on latent class growth model (LCGM). Methods: The clinical data and neurological function scores [National Institutes of Health Stroke Scale (NIHSS)] of 360 patients with spontaneous cerebral hemorrhage (June 2023 to June 2025) were retrospectively collected, and LCGM was used to identify potential categories of neurological recovery trajectories, analyze risk factors affecting poor recovery trajectories, and compare the prognosis of different trajectories [modified Rankin Scale (mRS), Glasgow Outcome Score (GOS)]. Results: The LCGM model fitting results showed that the three types of trajectories were the optimal fitting model, and 360 patients with spontaneous cerebral hemorrhage could be divided into 139 cases (38.61%) of rapid recovery type, 154 cases (42.78%) of stable recovery type, and 67 cases (18.61%) of poor recovery type; admission to Glasgow Coma Scale (GCS) score, initial NIHSS score, mechanical ventilation, use of vasoactive drugs and hematoma volume are independent influencing factors of poor neurological recovery (P＜0.05); in terms of prognosis, there were significant differences in mRS and GOS scores among the three groups of patients (P＜0.05).Conclusion: Based on LCGM, it is possible to effectively identify the heterogeneous trajectories of neurological function recovery in patients with intracerebral hemorrhage (ICH), while also identifying independent risk factors influencing neurological function repair and establishing associations between different recovery trajectories and prognosis.

摘要：目的 分析2022—2024年深圳市福田区危重症孕产妇不同亚组（不同并发症/合并症）的流行病学特征、病因构成及相关因素，为优化区域孕产妇健康管理提供依据。方法 基于福田区危重症孕产妇监测网络，对2022年1月1日至2024年12月31日期间107921例孕产妇个案资料进行回顾性描述性分析，采用描述性流行病学方法及卡方检验分析不同因素与危重症主要并发症的关联。结果 深圳市福田区3年间危重症孕产妇共729例，总体发生率为6.75‰。各年度发生率分别为2022年6.67‰、2023年7.38‰和2024年6.33‰。危重症孕产妇中，≥35岁者占33.7%，本科及以上学历者占53.8%。初检妊娠风险评级为黄色者占比最高（41.98%），高危者占21.9%。最常见并发症为产后出血（43.89%），其次为宫缩乏力（17.28%）、前置胎盘（16.59%）、子痫/子痫前期（14.67%）和胎盘植入（13.99%）。血液系统疾病为最常见合并症（57.75%），内分泌系统疾病次之（24.42%）。单因素分析显示，产后出血的发生与高龄、产检次数不足5次、经产妇身份存在统计学关联（均P<0.05）；前置胎盘的发生与高龄、低学历、非汉族、初检高危评级、产检不足5次、经产存在统计学关联（均P<0.05）。结论 深圳市福田区危重症孕产妇发生率约为6.75‰，产后出血和前置胎盘为主要并发症。单因素分析显示，高龄、产检不足、初检高危分级及经产与上述主要并发症的发生相关。应加强动态妊娠风险管理和多学科协作，完善产科早期预警体系，以降低危重症孕产妇发生率，提高母婴安全水平。

Abstract: Objective To analyze the epidemiological characteristics, etiology composition, and related factors of critically ill pregnant women in Futian District, Shenzhen, from 2022 to 2024. Methods Based on the surveillance network, a retrospective descriptive analysis was conducted on 107,921 pregnant women. Chi-square tests were used to analyze the association between different factors and major complications. Results A total of 729 critically ill pregnant women were identified (overall incidence 6.75‰).??The most common complication was postpartum hemorrhage (43.89%), followed by uterine atony (17.28%), placenta previa (16.59%), eclampsia/preeclampsia (14.67%), and placenta accreta (13.99%). Univariate analysis showed that postpartum hemorrhage was statistically associated with advanced age, <5 antenatal visits, and multiparity (all P<0.05). Placenta previa was statistically associated with advanced age, low education level, non-Han ethnicity, high-risk initial assessment, <5 antenatal visits, and multiparity (all P<0.05). Conclusion The incidence of critically ill pregnant women in Futian District is approximately 6.75‰. Univariate analysis suggested that advanced age, insufficient antenatal visits, high-risk classification, and multiparity were associated with the main complications. Dynamic risk management and multidisciplinary collaboration should be strengthened.

To evaluate the effectiveness of an intervention combining Root Cause Analysis (RCA)–based quality management and Psychological Capital (PsyCap) theory in reducing communication interruptions and improving communication quality and teamwork in surgical safety check teams. Methods: Eighty surgical team members from a tertiary hospital (January 2025 - December 2025.) were assigned to a control group or an intervention group according to operating room allocation (40 per group). The control group followed routine surgical safety check procedures, whereas the intervention group additionally received an RCA-guided workflow analysis and a PsyCap-based communication enhancement program. Post-intervention outcomes included communication interruption rate, execution quality and efficiency of safety checks, Psychological Capital Questionnaire (PCQ-24) scores, and TeamSTEPPS Teamwork Perceptions Questionnaire (T-TPQ) scores. Results: The intervention group demonstrated a significantly lower communication interruption rate compared with the control group (P＜0.05). Execution quality and communication efficiency were significantly improved in the intervention group (P＜0.001). PCQ-24 total and subscale scores were significantly higher in the intervention group than in the control group (P＜0.001), as were T-TPQ total and subscale scores (P＜0.001). Conclusion: Integrating RCA-based workflow optimization with PsyCap-oriented psychological and behavioral training can effectively enhance communication quality, reduce interruptions, and strengthen teamwork in surgical safety check teams. The combined model has strong applicability and potential for wider clinical promotion.
