Objective To evaluate the effect of fentanyl on the efficacy of low-dose ropivacaine for spinal anesthesia in patients undergoing anorectal surgery.Methods Forty ASA Ⅰ or Ⅱ patients,aged 20-55 yr,with body mass index 18-28 kg/m2,scheduled for anorectal surgery,were randomly divided into 2 groups (n =20 each):0.5％ ropivacaine 7.5 mg group (group R) and 0.3％ ropivacaine 6.0 mg+ fentanyl 10 μg group (group RF).A catheter was implanted into the subarachnoid space (L3.4 interspace) and advanced caudally until lumbar region.Group R received hyperbaric 0.5％ ropivacaine 1.5 ml.Group RF received 2.0 ml mixture of hyperbaric 0.3％ ropivacaine 6.0 mg and fentanyl 10μg.The onset time of sensory and motor block,upper level of sensory block,and duration of sensory and motor block were recorded.Motor block was assessed by modified Bromage scale.Results Compared with group R,the duration of sensory and motor block was significantly shortened,and modified Bromage scores were significantly decreased in group RF (P ＜ 0.05 or 0.01),and no significant change was found in the onset time of sensory and motor block and upper level of sensory block between the two groups (P ＞ 0.05).Conclusion 0.3 ％ ropivacaine 6.0 mg combined with fentanyl 10 μg provides satisfactory spinal anesthesia for anorectal surgery,with lower degree and faster recovery of motor block.

Objective To evaluate the effects of different head-down tilt (HDT) angles on respiratory mechanics and cerebral circulation during laparoscopic radical resection of rectal carcinoma in the patients.Methods Thirty patients of both sexes,aged 40-64 yr,of ASA physical status Ⅰ or Ⅱ,with body mass index ＜ 30 kg/m2,scheduled for elective laparoscopic radical resection of rectal carcinoma,were included in the study.Anesthesia was induced with midazolam,fentanyl,propofol and cis-atracurium and maintained with targetcontrolled infusion of propofol and remifentanil and cis-atracurium when needed.At 5 min after supine position,5 min after 30° HDT,5 min after 35° HDT,5 min after 40° HDT,and 30 min after pneumoperitoneum (T1-5),airway pressure (Paw),peak airway pressure (PIP),lung compliance (Cpat) and jugular bulb blood pressure (JBP) were recorded.Blood samples were taken from the radial artery and jugular bulb for blood gas analysis and arterial partial pressure of oxygen (PaO2),partial pressure of carbon dioxide in artery (PaCO2),arterial oxygen saturation (SaO2),jugular bulb oxygen partial pressure (PjvO2),and jugular bulb venous saturation (SjvO2) were recorded at each time point mentioned above.Results Paw,PIP,MAP,PaCO2,JBP,PjvO2 and SjvO2 were significantly increased as compared with those obtained when the patients were in supine position,increased gradually with the increasing HDT angles,and decreased to the level obtained when the patients were in supine position at 30 min after pneumoperitoneum.Cpat and PaO2 were significantly decreased as compared with those obtained when the patients were in supine position decreased gradually with the decreasing HDT angles,and increased to the level obtained when the patients were in supine position at 30 min after pneumoperitoneum.Conclusion HDT-induced effects on respiratory mechanics and cerebral circulation increase with increasing angles during laparoscopic radical resection of rectal carcinoma; thus the optimum HDT angle is smaller than 40° for the patients undergoing this kind of surgery.

Objective To investigate the level of spirituality in cancer patients in a 3A grade hospital of Changsha and to analyze the influencing factors. Methods In this study, convenience sampling method was used to select 196 patients with cancer from three hospitals in a 3A grade hospital of Changsha from October 2016 to October 2017. The general situation questionnaire, the functional assessment of chronic illness therapy (FACIT-Sp-12), the social support scale and the post traumatic growth inventory were used to investigate the patient′s spiritual status and to analyze the influencing factors. Results The total spiritual score of cancer patients was 31.09 ± 8.89, the score of meaning dimension was 10.71±2.75, and the peace dimension was 9.84±3.19 and the belief dimension was 10.54± 2.98. The results of multiple regression analysis showed that age, cancer stage, education level, the subjective support of Social Support, relating to others and personal strength of The Posttraumatic Growth were the influencing factors for the spiritual status of cancer patients. Conclusions the spiritual status of cancer patients in a 3A grade hospital of Changsha is at medium level, and the spiritual status is closely related to age, education level, cancer stage, social support and post traumatic growth level. Medical staff should provide spiritual care for patients to improve their psychology and Mental Health and quality of life.

Through the development of the guidance for case handling of radiological health law enforcement, health supervisors are instructed to accurately grasp the key points of law enforcement and case handling and standardize the process of collecting evidence and law application to ensure the correct implementation of administrative penalty. This article explains the structure and content of the guidance for case handling of radiological health law enforcement by taking the case of arranging radiation workers who have not undergone an occupational health examination to engage in the radiological occupational-disease-inductive operation in medical institutions as an example.

Objective To evaluate the efficacy of preoperative transversus abdominis plane (TAP) block for improving analgesia after radical resection of colorectal cancer in elderly patients.Methods Fiftysix American Society of Anesthesiologists physical status Ⅱ or Ⅲ patients of both sexes,aged 75-86 yr,weighing 52-78 kg,scheduled for elective radical resection of colorectal cancer under general anesthesia,were divided into 2 groups (n=28 each) using a random number table:TAP block group (group T) and control group (group C).After anesthesia induction,ultrasound-guided bilateral TAP block was performed,and 0.40％ ropivacaine 25 ml was injected into each side in group T.Both groups received patientcontrolled intravenous analgesia (PCIA) with fentanyl after surgery.PCIA solution contained fentanyl 600 μg and azasetron 10 mg in 100 ml of normal saline.The PCIA pump was set up with a 2 ml bolus dose,a 15 min lockout interval and background infusion at a rate of 2 ml/h,and visual analogue scale score was maintained≤ 3.When the visual analogue scale score＞3,tramadol 50-100 mg was intravenously injected as rescue analgesic.The number of patients requiring rescue analgesic,consumption of fentanyl during PCIA and the number of successfully delivered doses were recorded within 24 h after surgery.The adverse reactions such as hematoma at the puncture site,nausea and vomiting,respiratory depression,chest tightness and pruritus were recorded.Results Compared with group C,the number of patients requiring rescue analgesic was significantly decreased,and the consumption of fentanyl and the number of successfully delivered doses during PCIA were decreased in group T (P＜0.05).No hematoma was found at the puncture site in group T.No respiratory depression,chest tightness or pruritus was found in the two groups,and there were no significant differences in the incidence of nausea and vomiting between the two groups (P＞0.05).Conclusion Preoperative TAP block can reduce the consumption of fentanyl and enhance the efficacy of analgesia after radical resection of colorectal cancer in elderly patients.

Objective To analyze the influencing factors and benchmark value of anesthesia cost in GB25 group in CHS-DRG Group Division Strategy(1.0),and explore the cost control strategy for surgical patients.Methods The data of 152 GB25 cases in sample hospitals were analyzed statistically.Through single factor analysis and multiple stepwise regression analysis,the influencing factors of anesthesia expenses were analyzed,and the evaluation system of hospital anesthesia expenses was built according to the payment standard of GB25 group and the average level of the city.Results Univariate analysis showed that there was significant difference in the influence of laparoscopic surgery or not,operation duration and anesthesiologist on anesthesia cost(P＜0.05);Stepwise regression further analysis showed that the length of operation and the anesthesiologist were the main influencing factors of anesthesia costs.Early warning shall be given when the anesthetic cost is greater than the median in the hospital,and rewards shall be given when the anesthetic cost is less than the average level in the city.Conclusion Hospitals should pay attention to standardize the diagnosis and treatment process,shorten the operation time,and reduce the anesthesia cost.At the same time,they should actively promote the clinical pathway management,and establish and improve the internal assessment mechanism of DRG.

BACKGROUND:The number of hip fracture patients with dementia is increasing with an aging population,posing challenges for surgical treatment. OBJECTIVE:To determine the effect of dementia on postoperative complications in older patients with hip fractures. METHODS:Patients aged over 60 years old with hip fractures from 2000 to 2019 at Chinese PLA General Hospital were included.Dementia patients with a preexisting diagnosis of dementia at admission were identified.Each dementia patient was matched,for age±5 years,gender,and fracture type with 10 non-dementia patients.The differences in postoperative complications were compared between the two groups,including pneumonia,respiratory failure,gastrointestinal bleeding,urinary tract infection,surgical site infection,deep venous thrombosis,pulmonary embolism,angina pectoris,arrhythmia,heart failure,myocardial infarction,stroke,and death.The impact of dementia on major complications was evaluated using multivariate conditional logistic regression. RESULTS AND CONCLUSION:A total of 2 887 patients were included,of whom 125(4.3%)were dementia patients and matched with 1 243 non-dementia patients.The average age of dementia patients was(80.6±7.4)years;64.8%were female;53.6%were intertrochanteric fractures,and 46.4%were femoral neck fractures.Major complications occurred in 25(20.0%)patients with dementia and 123(9.9%)patients without dementia(P<0.01).The risk of major complications was 200.0 per 1 000 persons(95%CI,139.3-278.6)in dementia patients and 99.0 per 1 000 persons(95%CI,83.6-116.9)in non-dementia patients.Multivariate conditional logistic regression showed that a 2-fold risk of major postoperative complications after hip fracture surgery was found in dementia patients than in those without dementia(adjusted OR,2.11;95%CI,1.08-4.10).The results show that dementia is an independent risk factor for postoperative complications in elderly patients with hip fractures.Appropriate preoperative risk assessment and corresponding preventive and therapeutic measures should be given to this vulnerable population to mitigate postoperative complications.

OBJECTIVE To provide a reference for the standardized treatment of chronic obstructive pulmonary disease （COPD） and the adjustment of therapeutic drugs for COPD in the national essential medicine list. METHODS Relevant clinical experts， pharmaceutical experts and medical insurance experts were invited to sort out the COPD treatment drugs involved in the domestic and foreign COPD clinical guidelines， the national essential medicine list， the WHO standard list of essential medicine， the national medical insurance catalogue， and comparatively analyzed the COPD treatment drugs. RESULTS & CONCLUSIONS Compared with domestic clinical guidelines， foreign clinical guidelines included an additional COPD triple preparation， while involving fewer types of expectorants and antioxidants； there were only 12 kinds of COPD treatment drugs included in the WHO standard list of essential medicine， while there were 18 kinds in the national essential medicine list in China， and more theophylline drugs， expectorants and antioxidants were included. In addition， 15 kinds of COPD treatment drugs were found in both the national clinical guidelines and the national medical insurance catalogue， but not in the national essential medicine list， including terbutaline， levalbuterol hydrochloride， salmeterol， formoterol， indacaterol， beclometasone， mometasone furoate， salbutamol ipratropium， glycopyrronium formoterol， umeclidinium vilanterol， indacaterol glycopyrronium， beclometasone formoterol， budesonide/glycopyrrolate/formoterol fumarate， fluticasone furoate/vilanterol/umeclidinium， and fudosteine， which were mainly long-acting beta 2-agonists and COPD triple preparations. These drugs had certain evidence-based medicine evidence， their efficacy and economy had certain advantages， and their impact on the budget of the medical insurance fund was controllable. Therefore， it is suggested that the aforementioned drugs should be included in the essential medicines list in the subsequent update.
