ABSTRACT
OBJECTIVE: To investigate the effects of electroacupuncture pre-stimulation on perioperative neurocognitive disorders (PNDs) in patients undergoing colon cancer surgery. METHODS: A total of 80 elderly patients with colon cancer undergoing elective surgery were selected as subjects. Patients in an observation group (N=40) were given electroacupuncture pre-stimulation at Baihui and Dazhui points, while those in a control group (N=40) were given sham electroacupuncture pre-stimulation. The Mini-Mental State Examination (MMSE), self-rating anxiety scale (SAS), Activity of Daily Living Scale (ADL), as well as the levels of microtubule-associated protein light chain 3II (LC3-II), Bcl-2 homologous domain protein antibody 1 (Beclin-1) and central nerve specific protein S100ß before and after treatment were compared. RESULTS: Compared with those before treatment, no significant differences were found in the scores of MMSE, SAS and ADL at 7 d after treatment in both groups, while MMSE scores were significantly lower and the scores of SAS and ADL were obviously more at 1 d and 3 d after treatment in both groups. Moreover, at 1 d and 3 d after treatment, the MMSE score in the observation group was significantly higher than that in the control group, while the scores of SAS and ADL in the observation group were lower than those in the control group (all P<0.05). Compared with those after treatment in the control group, the level of S100ß was significantly decreased, while the levels of LC3-II and Beclin-1 were obviously increased in the observation group (all P<0.05). CONCLUSION: Electroacupuncture pre-stimulation at Baihui and Dazhui points could effectively reduce neurological damage and prevent PNDs in patients undergoing colon cancer surgery through improving the cognitive functions, anxiety states and self-care ability. The observed changes in levels of S100ß, LC3-II and Beclin-1 may be associated with the beneficial effects of electroacupuncture pre-stimulation on PNDs in these patients.
ABSTRACT
OBJECTIVE: To investigate the clinical effect of different doses of midazolam combined with fentanyl during painless bronchoscopy in adult patients. METHODS: In this retrospective study, a total of 200 patients who underwent painless bronchoscopy in The First People's Hospital of Wenling from January 2018 to January 2021 were selected as research subjects. These patients were assigned into an experimental group and a control group with 100 patients in each group. Patients from the experimental group were sedated with an intravenous infusion of 0.05 mg/kg midazolam and 0.2 µg/kg fentanyl, while patients from the control group were sedated using 0.1 mg/kg midazolam and 0.2 µg/kg fentanyl. The changes in heart rate (HR), saturation of pulse oximetry (SpO2), systolic blood pressure (SBP), and diastolic blood pressure (DBP) before and at 10 minutes after administration were compared between the two groups. Ramsay sedation scale, RSS agitation scale, awaking time, incidence of adverse reactions, and anesthetic effects were also compared. RESULTS: After medication, there was no significant difference in terms of HR, SBP, or DBP values between the two groups. The SpO2 value in the experimental group was higher than that in the control group (96.93±1.10% vs. 94.78±0.83%, P<0.05). Ramsay sedation scale of patients from the experimental group after medication was (3.88±0.66), which was significantly higher than that of the control group (2.32±0.63), while RSS agitation score in the experimental group was (1.08±0.16), lower than that of the control group (2.32±0.63). The awaking time in the experimental group was shorter than that in control group (43.60±3.30 min vs. 50.19±4.45 min, P<0.05). Moreover, the incidence of mild cough or no cough in the experimental group was significantly better than in the control group (P<0.05). The overall incidence of adverse reactions in the experimental group was lower than that of the control group (5.00% vs. 13.00%, P<0.05). In addition, the anesthetic effect in the experimental group was better than that of the control group (90% vs. 80%, P<0.05). CONCLUSION: The use of 0.05 mg/kg midazolam combined with 0.2 µg/kg fentanyl in adult painless bronchoscopy has little effect on SpO2 levels, possesses a good sedative and anesthetic effect, and reduces the awaking time, restlessness response, and adverse reactions.
ABSTRACT
Introduction: In patients undergoing cancer surgery, it is ambiguous whether propofol-based total intravenous anesthesia (TIVA) elicits a significantly higher overall survival rate than volatile anesthetics (VA). Consequently, evaluating the impact of TIVA and VA on long-term oncological outcomes is crucial. Aim: This study compared TIVA versus VA for cancer surgery patients and investigated the potential correlation between anesthetics and their long-term surgical outcomes. Material and methods: A comprehensive search of Medline, EMBASE, Scopus, and Cochrane Library identified English-language peer-reviewed journal papers. The statistical measurements of hazard ratio (HR) and 95% CI were calculated. We assessed heterogeneity using Cochrane Q and I2 statistics and the appropriate p-value. The analysis used RevMan 5.3. Results: The meta-analysis included 10 studies with 14036 cancer patients, 6264 of whom received TIVA and 7777 VA. In this study, we examined the long-term oncological outcomes of cancer surgery patients with TIVA and VA. Our data show that the TIVA group had a considerably higher overall survival rate (HR = 0.49, 95% CI: 0.30-0.80) and recurrence-free survival rate (HR = 0.56, 95% CI: 0.32-0.97). Each outcome was statistically significant (p < 0.05). Conclusions: The present study concludes that TIVA is a more effective anesthetic agent than VA in obtaining better long-term oncological outcomes in cancer patients after surgery as it provides a higher overall survival rate, a higher recurrence-free survival rate and fewer post-operative pathological findings in patients who have undergone surgery for cancer as compared to VA.
ABSTRACT
This paper aimed to study the application of local anesthetics combined with transversus abdominis plane (TAP) block in gynecological laparoscopy (GLS) surgery during perioperative period under the guidance of ultrasound image enhanced by the wavelet transform image enhancement (WTIE) algorithm. 56 patients who underwent GLS surgery in hospital were selected and classified as the infiltrating group and block group. The puncture needle was guided by ultrasound images under WTIE algorithm, and 0.375% ropivacaine was adopted to block TAP. The results showed that the dosage of propofol in the infiltrating group (313.23 ± 19.67 mg) was remarkably inferior to the infiltrating group (377.67 ± 21.56 mg) (P < 0.05). The hospitalization time of patients in the infiltrating group (2.14 ± 0.18 days) was obviously shorter than that of the infiltrating group (3.23 ± 0.27 days) (P < 0.05). 3 h, 6 h, and 12 h after the operation, the visual analogue scores (3.82 ± 1.58 points, 2.97 ± 1.53 points, and 1.38 ± 0.57 points) of the patients in the infiltration group were considerably higher than the infiltrating group (2.31 ± 1.46 points, 1.06 ± 1.28 points, and 0.95 ± 0.43 points) (P < 0.05). 3 h, 6 h, and 12 h after the operation, the number of patients in the infiltrating group who used tramadol for salvage analgesia (2 cases, 1 case, and 1 case) was notably less than that in the infiltration group (9 cases, 7 cases, and 3 cases) (P < 0.05). In short, local anesthetics combined with TAP block can reduce postoperative VAS score and postoperative nausea and vomiting (PONV) score, which also reduced the incidence of postoperative analgesia.
