Objective To compare the degree of pain in patients after radical gastrectomy under different anesthetic regimens.Methods One hundred and two ASA Ⅰ or Ⅱ patients of both sexes,aged 50-75 yr,weighing 45-70 kg,undergoing elective radical gastrectomy,were randomly divided into 3 groups ( n =34 each):general anesthesia (GA) group,combined general-subcostal transversus abdominis plane block (CGTA) group and combined general-epidural anesthesia (CGEA) group.The patients were sent to the postanesthesia care unit (PACU) after tracheal extubation,and the VAS score on arrival in the PACU was recorded.The degree of pain was evaluated by VAS score,and when VAS scores ＞ 3,the patients received intravenous morphine titration.When VAS scores ≤ 3,morphine titration was stopped and all the patients were connected to patient-controlled intravenous analgesia and/or epidural analgesia pump.The total amount of morphine consumed was recorded at the end of titration,and the occurrence of adverse reactions was also observed.Results Compared with groups GA and CGTA,the incidence of moderate to severe postoperative pain was significantly decreased in group CGEA (P ＜0.01).The incidence of severe postoperative pain,the VAS score on arrival in the PACU and the total amount of morphine consumed were decreased gradually in groups GA,CGTA and CGEA ( P ＜ 0.01 ).The incidence of sedation was significantly lower in group CGEA than in group GA (P ＜ 0.01 ).There were no significant differences in the other adverse reactions among the three groups ( P ＞ 0.05 ).Conclusion The degree of pain is reduced gradually in patients after radical gastrectomy under GA,CGTA and CGEA.

Objective To evaluate the efficacy of the anterior approach to quadratus lumborum block in each abdominal and back region.Methods Twelve healthy volunteers of both sexes,aged 18-45 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,with body mass index of 18-30 kg/m2,were enrolled in the study.Quadratus lumborum block was performed via the anterior approach under the guidance of ultrasound with 0.375％ ropivacaine 20 ml.The block was assessed by cold stimulation (ice cake) in each abdominal and back region (the right side of the body was divided into 15 regions using the anatomical landmarks on the body surface).The positive condition in each region was recorded at 30 min after administration.Results The region in which the positive rate ≤ 5％ was 0.The regions in which the positive rate ＞5％-20％ were 1 and 13 regions.The regions in which the positive rate ＞20％-50％ were 2,3 and 4 regions.The regions in which the positive rate ＞50％-70％ were 6,7 and 10 regions.The regions in which the positive rate ＞70％-＜95％ were 5,14 and 15 regions.The regions in which the positive rate ≥95％ were 8,9,11 and 12 regions.Conclusion The anterior approach to quadratus lumborum block is effective in the middle-lower region of the anterior abdominal wall on the blocked side.

Objective To explore the clinical efficacy and application value of hemivertebra resection for treating congenital ky‐phoscoliosis .Methods 30 cases of congenital kyphoscoliosis and hemivertebral deformity in our hospital from January 2011 to Jan‐uary 2013 were selected as the research subjects .Among them ,12 cases of simple vertebral and non‐structural bending were per‐formed the posterior hemivertebral resection and short segment pedicle screw fixation ;3 cases of complicating lordosis and hemiver‐tebral protruding to the ventral side were performed the anterior hemivertebral resection and bone graft fusion fixation ;15 cases of complicating structural compensatory curve were performed the posterior transpedicle hemivertebral resection and compensatory bend long segment fixation and fusion .The clinical effects of surgical treatment for all patients were performed the comparative a‐nalysis .Results The mean postoperative kyphosis Cobb angle and the average final follow‐up Cobb angle were (8 .6 ± 3 .14) °and (11 .2 ± 7 .23) °respectively .The ultimate orthopedic rate of kyphosis was 58 .6% ;the average postoperative Cobb angle and and the average final follow‐up Cobb angle of scoliosis were (12 .8 ± 5 .47)°and (16 .2 ± 6 .24)°respectively ,the final orthopedic rate of scoliosis was 66 .5% .The mean Cobb angle of kyphosis and scoliosis after operation was significantly less than that before opera‐tion ,the difference was statistically significant(P< 0 .05) .Kyphosis and scoliosis were significantly improved .No significant post‐operative complications occurred .The effects were satisfied by the patients .Conclusion The hemivertebral resection has significant effect for treating congenital kyphoscoliosis with high kyphoscoliosis orthopedic rate and is worthy of further clinical study .

Construction of smart hospitals is of great significance to the substantial development of medical institutions and the reform of medical and health systems and meanwhile it serves as a crucial support for the high-quality development of pub-lic hospitals.Guangdong Second Provincial General Hospital actively responds to national policies,constantly exploring standard-ized application of new smart medical technology.It has successfully built itself into a first full-scene smart hospital.Through gradually deepening the intelligent construction of hospitals,the hospital has achieved obvious achievements in hospital manage-ment such as medical services,medical resources,medical data,hospital operation logistics,and medical environment improve-ment.Their practical experience can provide references for the intelligent construction of hospitals domestically.
