ABSTRACT
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pulmonary function in the patients undergoing robot-assisted radical resection of colon cancer.Method:Ninety-four patients of either sex, aged 50-80 yr, with body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, with ARISCAT grade of medium risk, undergoing elective robot-assisted radical resection of colon cancer, were enrolled in this study. The patients were divided into TEAS group (group T, n=47) and sham-TEAS group (group S, n=47) using a random number table method. In group T, patients received 30 min of TEAS at Hegu (LI4), Quchi (LI11), Zusanli (ST36) and Feishu (BL13) between 5: 00 and 7: 00 a. m. from 1st day before operation to 3rd day after operation, with disperse-dense wave 2/100 Hz, and the stimulation intensity was the maximum intensity that the patient could tolerate. Patients in group S were also connected to the device without electrical stimulation. Both groups adopted lung-protective ventilation strategy during operation. The oxygenation index was calculated at the time of entering the operating room (T 0), 5 min after anesthesia induction (T 1), 5 min of pneumoperitoneum (T 2), 5 min after changing to Trendelenburg position (T 3) and immediately after the end of pneumoperitoneum (T 4). Peak airway pressure, plateau airway pressure, driving pressure and dynamic lung compliance were recorded at T 0-T 4. The serum concentration of lung Clara cell 16 kDa protein was recorded using enzyme-linked immunosorbent assay at T 0, T 4 and 2 h after extubation (T 5). On 1 day before operation and 1, 3 and 7 days after operation, the forced expiratory volume in the first second (FEV 1) and forced vital capacity (FVC) were measured, and the FEV 1/FVC was calculated, and the concentrations of serum tumor necrosis factor-alpha, interleukin-6 and cardiopulmonary resuscitation were simultaneously determined using enzyme-linked immunosorbent assay. The occurrence of pulmonary complications within 7 days after operation was recorded. Results:There was no significant difference in pH values, PaCO 2, oxygenation index, peak airway pressure, plateau airway pressure, driving pressure, and dynamic lung compliance at each time point between the two groups ( P>0.05). Compared with S group, the serum Clara cell 16 kDa protein concentrations were significantly decreased at T 5, FEV 1 and FVC were increased at 3 and 7 days after operation, the serum tumor necrosis factor-alpha, interleukin-6 and cardiopulmonary resuscitation concentrations were decreased at 1, 3 and 7 days after operation, the incidence of unexpected oxygen supply and total incidence of postoperative pulmonary complications were decreased ( P<0.05), and no significant change was found in FEV 1/FVC at each time point in T group ( P>0.05). Conclusions:TEAS can improve lung function in the patients undergoing robot-assisted radical resection of colon cancer.
ABSTRACT
Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation with midnight-noon ebb-flow acupoint selection on postoperative delirium (POD) in the patients undergoing radical resection of colorectal cancer.Methods:A total of 93 patients of either sex, aged ≥18 yr, with body mass index <30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, scheduled for elective radical resection of colorectal cancer under general anesthesia, were divided into 3 groups ( n=31 each) using a random number table method: control group (group C), common TEAS group (group CT), and midnight-noon ebb-flow acupoint selection TEAS group (group MT). The patients received TEAS at bilateral Hegu, Quchi and Shousanli acupoints at 6: 00 in group MT and at 18: 00 in group CT on the day of operation and 1-3 days after surgery, with a frequency of 2/100 Hz, disperse-dense waves, intensity the maximum current that could be tolerated, and each TEAS lasted for 30 min. In group C, only the electrodes were pasted at the same acupoints without electric current at 6: 00 am. The POD was evaluated by the Confusion Assessment Method (CAM) at 1, 3 and 5 days after operation (T 1-3). Blood samples were collected for determination of serum interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) concentrations at 1 day before operation and at T 1. The time to first flatus and defection and adverse reactions after operation were recorded. Results:Compared with group C, the CAM scores at each time point and incidence of POD were significantly decreased, the concentrations of IL-1β, TNF-a and IL-6 in serum were decreased at T 1, the time to the first flatus and defecation was shortened, and the incidence of abdominal distension after surgery was decreased in MT and CT groups ( P<0.05). Compared with group CT, the CAM scores at T 3 and incidence of POD were significantly decreased, the concentrations of TNF-a and IL-6 at T 1 were decreased, and the time to first defecation after operation was shortened in group MT ( P<0.05). Conclusions:TEAS guided by midnight-noon ebb-flow acupoint selection provides better efficacy than common TEAS in decreasing the risk of POD in the patients undergoing radical resection of colorectal cancer, which is helpful for the early postoperative recovery of patients.
ABSTRACT
Objective:To investigate the implementation status of appropriate technique of Traditional Chinese Medicine (TCM) in the perioperative period in China using questionnaires.Methods:From May to June 2022, the questionnaire designed by ourselves was sent to anesthesiologists participating in the survey through the WeChat platform nationwide, and the system automatically recorded the survey.Results:A total of 6 230 anesthesiologists participated in the questionnaire survey, there were 6 160 valid questionnaires, with an effective rate of 98.88%.The anesthesiologists participating in the questionnaire survey were distributed in 16 provincial administrative regions in China, of which the rate from tertiary hospitals was 32.59%, the rate from secondary hospitals was 67.41%, and the application rate of TCM appropriate techniques in the perioperative period was 9.8%.The application rate of TCM appropriate techniques in the perioperative period was higher in tertiary hospitals than in secondary hospitals (9.51% vs. 6.31%, P<0.05), and the application rate was significantly higher in TCM hospitals than in integrated Chinese and Western Medicine hospitals and Western medicine general hospitals (26.15% vs.7.26% vs. 2.49%, P<0.05). Among the provinces participating in the survey, Guangdong Province had the highest application rate of TCM appropriate techniques in the perioperative period (13.60%). In the anesthesiologists carried out TCM appropriate techniques in the perioperative period, the highest application rate of TCM appropriate techniques in non-drug therapy was 59.0%, and the highest application rate in abdominal surgery was 47.4%, and most anesthesiologists (68.1%) selected TCM appropriate techniques according to the type of surgery in patients.Anesthesiologists who applied TCM appropriate techniques in the perioperative period believed that TCM appropriate technique cloud reduce the development of nausea and vomiting in the perioperative period (66.8%), alleviate perioperative pain (54.8%), promote the recovery of perioperative gastrointestinal function (49.8%), and reduce the development of perioperative neurocognitive disorders (47.0%). The main reasons for the lack of TCM appropriate techniques in the perioperative period were the lack of standardized technical training and relevant guidelines (87.11%), the lack of relevant charging items (58.30%), the technical level of operators (46.20%), the lack of support by surgeons (43.40%), and the non-cooperation of patients (27.10%). Conclusions:At present, the application rate of TCM appropriate techniques in the perioperative period is generally low, and the application rate varies greatly among different provinces and hospitals of different levels.Publicity should be expanded through multiple channels, various forms of technical training should be carried out, the implementation plan and guidelines of TCM appropriate technologies should be continuously optimized, and the promotion and application of TCM appropriate techniques in the perioperative period should be strengthened.

ABSTRACT
Objective@#To compare the efficacy of intra-articular injection of autologous platelet-rich plasma (PRP) with that of sodium hyaluronate for patients with knee osteoarthritis (KOA).@*Methods@#Fifty KOA patients were randomly divided into a PRP group (n=25) and a sodium hyaluronate group (n=25). Those in the PRP group were injected intra-articularly with 5 ml of autologous PRP every 2 weeks for 6 consecutive weeks, while the sodium hyaluronate group was given intra-articular injections of 2 ml of sodium hyaluronate once a week for 6 weeks. Both groups performed isokinetic strength training three times a week for 6 weeks. Before as well as 6 weeks, 3 months, 6 months and 12 months after the treatment, both groups were followed and evaluated using the Western Ontario and McMaster University osteoarthritis index (WOMAC). A Biodex System 4 isometric muscle strength testing system was used to evaluate the knees′ peak torque (PT) in flexion and extension, total power (TW), and average power (AP).@*Results@#Before the treatment there were no significant differences in pain, stiffness or average WOMAC score between the two groups. Afterward significant improvement was observed in the pain, stiffness and WOMAC scores of both groups. Compared with the sodium hyaluronate group, significantly greater decreases in the average WOMAC pain score were observed in the PRP group after the different intervals. That was also true of the average stiffness scores and the overall average WOMAC scores after 6 and 12 months. The flexor and extensor PT, TW and AP at the angular velocities of 60°/s and 90°/s also improved significantly in both groups after 6 weeks and 12 months, with the improvement of the PRP group significantly greater than that in the control group at the same time points.@*Conclusion@#Intra-articular injection of either autologous PRP or sodium hyaluronate can effectively alleviate the clinical symptoms of KOA when combined with isokinetic strength training. However, PRP is the more effective. Its use is worthy of clinical application and promotion.
