Methods: Seventy-six cases of hemiplegia patients with ischemic stroke were divided into the treatment group and the control group(n=38 in each). Based on the Brunnstrom's stage of Xingnao Kaiqiao acupuncture combined with rehabilitation training was used in the treatment group, and the control group was given rehabilitation training. FuglMeyer Assessment of the upper extremity(FMA-UE), Action Research Arm Test(ARAT) and Simple Test for Evaluating hand Function(STEF) were adopted separately to compare scores before treatment and 8 weeks after treatment. Results: The difference was not statistically significant in the two groups of patients for comparison of FMA-UE, ARAT and STEF scores before treatment(P>0.05). The difference was statistically significant in the two groups of score comparison of FMA-UE, ARAT and STEF after treatment(P<0.05). Conclusion: The Xingnao Kaiqiao acupuncture has its unique advantages in improving recovery of motor function of upper limb and hand in recovery period after stroke.展开更多

Methods: From June 2021 to December 2021, 78 patients who underwent gastric cancer surgery in our hospital were selected for research. Combined with the random number table method, they were divided into the control group (providing routine nursing care in operating room) and the observation group (providing nursing intervention in operating room) with 39 patients in each group respectively. The body temperature of the two groups during operation, during abdominal closure and after operation, the time of leaving anesthesia room, extubation, postoperative wakefulness and hospitalization, degree of satisfaction with nursing work was compared. Results: Compared with the control group, the body temperature in the observation group tended to be more normal during operation, during abdominal closure and after operation (P 0.05). The time of leaving anesthesia room, extubation, postoperative wakefulness and hospitalization in the observation group were shorter than those in the control group (P 0.05). The satisfaction degree of the observation group with nursing work was higher than that of the control group (P 0.05). Conclusion: Nursing intervention in operating room is effective for gastric cancer patients in anesthesia recovery period, which can maintain their perioperative temperature stability, promote their postoperative recovery and enhance their satisfaction with nursing work.

Treatment modalities have been advancing, and the application of Enhanced Recovery After Surgery (ERAS) principles provides a new approach to postoperative recovery in patients. This study aims to investigate the clinical application effects of ERAS principles in single-level lumbar spinal stenosis surgery. Methods: This study included 64 patients who underwent lumbar fusion surgery in the Spinal Surgery Department of Baise People’s Hospital from July 2022 to July 2024. These patients were divided into an experimental group (ERAS group, 33 cases) and a control group (conventional group, 31 cases) based on perioperative care, receiving ERAS principles and traditional treatment, respectively. A comparison was made between the two groups in terms of gender, age, BMI, intraoperative blood loss, postoperative length of hospital stay, postoperative complications, hospital costs, VAS scores (preoperative/postoperative day 3), and ODI scores (preoperative/postoperative day 3). Results: There were no significant differences in gender, age, and BMI between the ERAS group and the conventional group (gender: χ2 = 0.5008, P = 0.4792;age: 54.55 ± 8.51 years vs. 57.39 ± 8.16 years, P = 0.0892;BMI: 25.11 ± 2.70 vs. 24.77 ± 2.75, P = 0.3098). However, during surgery, patients in the ERAS group had significantly less blood loss than those in the conventional group (197.58 ± 195.51ml vs. 438.71 ± 349.22 ml, P = 0.0006), and the postoperative length of hospital stay was significantly shorter (7.00 ± 2.24 days vs. 11.55 ± 5.23 days, P = 0.0000). On postoperative day 3, VAS scores were significantly better in the ERAS group compared to the conventional group (3.70 ± 0.88 vs. 4.32 ± 0.87, P = 0.0031), and the ODI scores showed significant improvement as well (46.00 ± 3.04 vs. 48.00 ± 3.39, P = 0.0078). Although there were no significant differences in postoperative complications and hospital costs (complications: 3 cases vs. 0 cases, P = 0.2154;hospital costs: 63524.29 ± 17891.80 RMB vs. 58733.84 ± 13280.82 RMB, P = 0.1154), ERAS demonstrated better postoperative recovery outcomes in single-level lumbar spinal stenosis surgery. Conclusion: The study results support the implementation of ERAS principles in single-level lumbar spinal stenosis surgery to promote rapid recovery, reduce healthcare resource consumption, and improve overall patient satisfaction.展开更多

The observed indicators included operation conditions, postoperative clinical indexes, and postoperative serum stress indexes. Measurement data following a normal distribution are presented as mean ± SD and were analyzed by t-test. Count data were analyzed by χ~2 test.RESULTS The operative time, volume of intraoperative blood loss, and number of patients with conversion to opensurgery were not significantly different between the two groups. Postoperative clinical indexes, including the time to initial anal exhaust, time to initial liquid diet intake, time to out-of-bed activity, and duration of hospital stay of patients without complications, were significantly different between the two groups(t = 2.045, 8.685, 2.580, and 4.650, respectively, P < 0.05 for all). However, the time to initial defecation, time to abdominal drainage-tube removal, and the early postoperative complications were not significantly different between the two groups. Regarding postoperative complications, on the first and third days after the operation, the white blood cell count(WBC) and C reactive protein(CRP) and interleukin-6(IL-6) levels in the ERAS group were significantly lower than those in the control group.CONCLUSION The perioperative ERAS program for total laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy is safe and effective and should be popularized. Additionally, this program can also reduce the duration of hospital stay and improve the degree of comfort and satisfaction of patients.展开更多

This concept not only helps patients speed up postoperative recovery, reduce the incidence of related complications and shorten hospital stays, but also has been proved to be effective and safe in the perioperative application of gastric cancer. This article reviews the clinical application and research progress of enhanced recovery after surgery in the perioperative period of advanced gastric cancer in the elderly.
文摘Objective:To compare the benefits of enhanced recovery after surgery(ERAS)pathways with traditional pathways for adult patients undergoing laparoscopic appendectomy.Methods:We looked for publications using the keywords“Enhanced Recovery After Surgery,”“Fast-track Surgery,”“Laparoscopic Appendectomy,”and“Laparoscopic Appendicectomy”in PubMed/Medline,Embase,and the Cochrane library.Operative time,lesser length of stay,oral intake timing,readmission rate,pain/satisfaction levels,readmission rate,and surgical site infections were recorded and analyzed.Results:A total of 95 articles from registers and 161 articles from databases were identified.Three eligible studies were included.The ERAS pathways had a lesser length of stay[Z=2.06,MD=−1.05,95%CI=(−2.04,−0.05),P=0.04]and an earlier start to postoperative feeds[Z=6.22,MD=−267.49,95%CI=(−351.80,−183.19),P<001].Conclusions:ERAS pathways have a shorter length of stay and earlier postoperative feed initiation for adult patients undergoing laparoscopic appendectomy compared with standard care.Both approaches have similar operative time,surgical site infection incidence,and readmission rate.Clinical registration:This review is registered with INPLASY202280005.
