[PMID: 37847474 PMCID: PMC10754746 DOI: 10.1007/s41999-023-00873-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 09/27/2023] [Indexed: 10/18/2023]
Abstract
METHODS Patients undergoing elective laparoscopic radical resection of colorectal cancer from July 2019 to May 2021 were selected. The patients were assigned to Ai-PCIA group and control group. Ai-PCIA group received postoperative analgesia management and effect evaluation through intelligent wireless analgesia system + postoperative follow-up twice a day, while control group received analgesia management and effect evaluation through ward physician feedback + postoperative follow-up twice a day. The pain numerical score (NRS), Richards-Campbell Sleep Scale (RCSQ), and adverse outcomes were collected and compared. RESULTS A total of 60 patients (20 females and 40 males with average (78.26 ± 6.42) years old) were included. The NRS scores at rest and during activity of the Ai-PCA group at 8, 12, and 24 h after the operation were significantly lower than that of the control group (all P < 0.05). The RCSQ score of Ai-PCA group was significantly higher than that of control group on the 1st and 2nd days after operation (all P < 0.05). There were no significant differences in the incidence of dizziness and nausea, vomiting, and myocardial ischemia (all P > 0.05). CONCLUSIONS Ai-PCIA can improve the analgesic effect and sleep quality of older patients after laparoscopic radical resection, which may be promoted in clinical analgesia practice.

Index of consciousness monitoring during general anesthesia may effectively enhance rehabilitation in elderly patients undergoing laparoscopic urological surgery: a randomized controlled clinical trial. BMC Anesthesiol 2023; 23:331. [PMID: 37794331 PMCID: PMC10548750 DOI: 10.1186/s12871-023-02300-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Accepted: 09/27/2023] [Indexed: 10/06/2023] Open
Abstract
BACKGROUND Based on electroencephalogram (EEG) analysis, index of consciousness (IoC) monitoring is a new technique for monitoring anesthesia depth. IoC is divided into IoC1 (depth of sedation) and IoC2 (depth of analgesia). The potential for concurrent monitoring of IoC1 and IoC2 to expedite postoperative convalescence remains to be elucidated. We investigated whether combined monitoring of IoC1 and IoC2 can effectively enhances postoperative recovery compared with bispectral index (BIS) in elderly patients undergoing laparoscopic urological surgery under general anesthesia. METHODS In this prospective, controlled, double-blinded trail, 120 patients aged 65 years or older were arbitrarily assigned to either the IoC group or the control group (BIS monitoring). All patients underwent blood gas analysis at T1 (before anesthesia induction) and T2 (the end of operation). The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were administered to all patients at T0 (1 day before surgery) and T4 (7 days after surgery). Serum concentrations of C-reactive protein (CRP) and glial fibrillary acid protein (GFAP) were assessed at T1, T2, and T3 (24 h after surgery). Postoperative complications and the duration of hospitalization were subjected to comparative evaluation. RESULTS The incidence of postoperative cognitive dysfunction (POCD) was notably lower in the IoC group (10%) than in the control group (31.7%) (P = 0.003). Postoperative serum CRP and GFAP concentrations exhibited significant differences at time points T2 (CRP: P = 0.000; GFAP: P = 0.000) and T3 (CRP: P = 0.003; GFAP: P = 0.008). Postoperative blood glucose levels (P = 0.000) and the overall rate of complications (P = 0.037) were significantly lower in Group IoC than in Group control. CONCLUSION The employment of IoC monitoring for the management of elderly surgical patients can accelerate postoperative convalescence by mitigating intraoperative stress and reducing peripheral and central inflammatory injury.

Abstract
Objective To determine the effect of laparoscopic complete mesocolic excision combined with immunotherapy and its impact on immune function and tumor markers in elderly patients with colon cancer. Methods This is a clinical comparative study. Eighty elderly patients with colon cancer hospitalized in the No.2 Hospital of Baoding from May 2020 to May 2022 were randomly divided into two groups, with 40 cases in each group. Patients in the study group received laparoscopic complete mesocolic resection combined with ubenimex orally. While patients in the control group received routine open surgery. The surgical indexes, surgical complications, and the changes of immune molecules and tumor markers before and after treatment were compared between the two groups. Results The amount of intraoperative bleeding, retention time of drainage tube and postoperative length of stay in the hospital in the study group were significantly better than those in the control group (p=0.000). The incision length of the study group was significantly shorter than that of the control group, the number of lymph nodes removed during the operation was significantly higher than that of the control group, and the incidence of surgical complications was significantly lower than that of the control group (p<0.05). After treatment, the levels of immune molecules in the study group were remarkably higher than those in the control group (p<0.05), while the levels of tumor markers were much lower than those in the latter group (p=0.000). Conclusion Laparoscopic complete mesocolic excision combined with immunotherapy exhibits a superior therapeutic effect to traditional open surgery in elderly patients with colon cancer, and is worthy of clinical promotion.

Abstract
INTRODUCTION The adverse effects of general anaesthetic drugs (especially opioids) cannot be ignored. However, current nociceptive-monitoring techniques still lack consistency in guiding the use of opioids. This trial will study the demand for opioid use and patient prognosis in qCON and qNOX-guided general anaesthesia management. METHODS AND ANALYSIS This prospective, randomised, controlled trial will randomly recruit 124 patients undergoing general anaesthesia for non-cardiac surgery in equal numbers to either the qCON or BIS group. The qCON group will adjust intraoperative propofol and remifentanil dosage according to qCON and qNOX values, while the BIS group will adjust according to BIS values and haemodynamic fluctuations. The differences between the two groups will be observed in remifentanil dosing and prognosis. The primary outcome will be intraoperative remifentanil use. Secondary outcomes will include propofol consumption; the predictive ability of BIS, qCON and qNOX on conscious responses, noxious stimulus and body movements; and changes in cognitive function at 90 days postoperatively. ETHICS AND DISSEMINATION This study involves human participants and was approved by the Ethics Committee of the Tianjin Medical University General Hospital (IRB2022-YX-075-01). Participants gave informed consent to participate in the study before taking part. The study results will be published in peer-reviewed journals and presented at relevant academic conferences.

Abstract
OBJECTIVE To analyze the gastrointestinal function and prognostic value of tumor markers (TMs) in patients with laparoscopic radical resection of colorectal cancer (LRRCC). METHODS The research population of this retrospective study comprised 141 patients with CC who received treatment in the Zhongshan Hospital of Xiamen University between July 2017 and August 2018, including 74 cases (observation group, OG) treated with LRRCC and 67 cases (control group, CG) undergoing open surgery (OS). Postoperative gastrointestinal function and complications were recorded. Besides, alterations in serum TMs carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), and the 3-years survival of patients were observed. Receiver operating characteristic (ROC) curves were used to determine the prognostic value of TMs. Risk factors affecting the prognosis of LRRCC patients were analyzed by the Cox regression model. RESULTS Significantly higher levels of motilin (MOT) and gastrin (GT) were determined in OG compared with CG. The two groups showed no notable difference in the postoperative complication rate. Postoperative serum CEA and CA199 levels were obviously lower in OG as compared with CG. A higher 3-year survival rate was determined in OG. The areas under the receiver operating characteristic (ROC) curve (AUCs) of CEA and CA19-9 levels in predicting patients' 3-year survival were 0.826 and 0.867, respectively. According to the Cox regression analysis, tumor diameter, lymph node involvement, TNM staging, vascular invasion, CEA, and CA19-9 were independent risk factors for poor prognosis of LRRCC patients. CONCLUSIONS LRRCC is well-tolerated by patients with CC and contributes to favorable outcomes. Besides, CEA and CA19-9, the two TMs, may be candidate prognostic markers for patients undergoing LRRCC.

Abstract
Objective To observe the effect of dexmedetomidine-assisted intravenous inhalation combined anesthesia on cerebral oxygen metabolism and serum Th1/Th2 levels in elderly patients with colorectal cancer. Method From April 2018 to May 2020,100 elderly patients undergoing elective laparoscopic radical resection of colorectal cancer were prospectively selected and randomly divided into observation group and control group. Before induction of anesthesia, the loading dose of dexmedetomidine was given at 0.5 μg/kg, and the infusion time was 15 min. After tracheal intubation, 0.4 μg/kg/h dexmedetomidine was continuously pumped, and the infusion was stopped 40 min before the end of the operation. In the control group, the same amount of 0.9% sodium chloride was injected intravenously in the same way. 30 min before induction of anesthesia (T0), immediately before induction of anesthesia (T1), immediately after tracheal intubation (T2), 40 min before operation (T3), and immediately after operation (T4), record the blood oxygen content of the artery and internal jugular vein Difference (D(a-jv)O2), brain oxygen uptake rate (COER%), brain oxygen saturation (rSO2) mean. VAS scale, Ramsay scale, MoCA scale were taken at 6, 12, 24, and 48 h postoperatively to evaluate analgesia, sedation, and cognitive function. And monitor the levels of interferon-γ (IFN-γ), interleukin-4 (IL-4), myelin basic protein (MBP), neuron-specific enolase (NSE) and S100β. The occurrence of restlessness and adverse reactions during the recovery period of the two groups were compared. Result The levels of D(a-jv)O2, COER%, and rSO2 in the control group and observation group were higher than the preoperative basic values at T2, T3, and T4 (P < 0.05); The levels of D(a-jv)O2, COER%, and rSO2 in the observation group were lower than those in the control group at T2, T3, and T4 (P < 0.05). The VAS score and Ramsay score of the observation group were lower than those of the control group at 6, 12, 24, and 48 h after surgery, while the MoCA score was higher than that of the control group (P < 0.05). In addition, the serum IFN-γ, MBP, NSE and S100β levels of the observation group were lower than those of the control group (P < 0.05), and the ratio of IFN-γ/IL-4 was higher than that of the control group (P < 0.05). The overall incidence of adverse reactions in the observation group was lower than that in the control group [32.0% (16/50) vs. 12.0% (6/50), P < 0.05]. Conclusion Dexmedetomidine-assisted combined intravenous and inhalation anesthesia is beneficial to reduce perioperative cerebral oxygen metabolism and improve postoperative immunosuppression in elderly patients with colorectal cancer. It has a certain protective effect on nerve injury after operation, thus improving the cognitive function of patients and reducing the occurrence of adverse reactions.

Abstract
OBJECTIVE To investigate the effect of general anesthesia combined with epidural anesthesia on circulation and stress response of patients undergoing hysterectomy. METHODS A total of 97 patients undergoing hysterectomy in our hospital from December 2017 to December 2019 were recruited as the research participants, of whom 44 patients (general anesthesia group) received general anesthesia and 53 patients (joint group) received general anesthesia combined with epidural anesthesia during operation. The hemodynamic indexes, anesthetic effect, anesthetic recovery effect, cognitive function, and stress substance levels of the two groups were compared. RESULTS Compared with the general anesthesia group, the SBP and HR of the patients in the joint group were more stable, and the anesthesia effect and recovery effect in the joint group were better. The MMSE score of the joint group at 6 h and 12 h after anesthesia was significantly higher than that of the general anesthesia group (P < 0.001). There was no significant difference in the levels of adrenaline and norepinephrine between the two groups before operation (P > 0.05). The levels of stress substances in the two groups increased at 30 min after operation (P < 0.001), and those in the joint group were significantly lower than those in the control group (P < 0.001). CONCLUSION Compared with general anesthesia, general anesthesia combined with epidural anesthesia produces better anesthetic effect in hysterectomy, has less influence on patients' circulatory response and can reduce stress response.
