Objective To compare pharmacodynamics of rocuronium in neonates,infants,young children and children.Methods One hundred and sixty ASA Ⅰ or Ⅱ pediatric patients undergoing elective surgicalprocedures under total intravenous anesthesia(TIVA)were divided into 4 groups according to ages(n=40 each):neonate group(0-28d),infant group(28 d0.05).Onset time of muscle relaxation.clinical duration and total duration were significantly shorter and recovery index lower in the other 3 groups than in neonate group(P<0.01).but there was nosignificant difference in the duration of peak effect among the 4 groups(P>0.05).ED50,ED90 and ED95 of rocuronium were significantly higher in children group than in young children group(P<0.01).Conclusions There are significant differences in dose-effect and time-effect relationships among different age children and neonate is more sensitive to rocuronium than the other age children.

Objective To observe the clinical efficacy of navel acupuncture in treating lumbar spinal stenosis. Method A total of 120 patients with lumbar spinal stenosis were randomized into a treatment group and a control group, 60 cases each. The treatment group was intervened by navel acupuncture based on syndrome differentiation of traditional Chinese medicine, while the control group was intervened by oral administration of Bulleyaconitine A tablets, 10 d as a treatment course, for successive 2 courses. The Visual Analogue Scale (VAS) was observed before and after the intervention, and the clinical efficacies were compared.Result The total effective rate was 98.3% in the treatment group versus 76.6% in the control group, and the between-group difference was statistically significant (P<0.01). The VAS scores were significantly changed after the intervention in both groups (P<0.05); the VAS score in the treatment group was significantly different from that in the control group after the treatment (P<0.05).Conclusion Navel acupuncture is an effective approach in treating lumbar spinal stenosis.

Objective To investigate the effect of various doses of dezocine on the prevention of emergence agitation after sevoflurane anesthesia in children .Methods 100 children aged from 1 to 3 years old were randomly divided into 4 groups with 25 cases each :the 0 .03 mg/kg dezocine group (group D1) ,the 0 .05 mg /kg dezocine group (group D2) ,the 0 .10 mg/kg dezocine group (group D3) and the control group .Anaesthesia was induced with 6% sevoflurane and 1 μg/kg remifentanil .Anaesthesia was maintained with 1 .5% - 2 .5% sevoflurane and remifentanil .Different doses of dezocine 0 .03 mg/kg ,0 .05 mg/kg ,0 .10 mg/kg ,and the same volume saline were administered before surgery .The incidence of emergence agitation was assessed with 5 points scale and the severity of emergence agitation was assessed with Pediatric Anesthesia Emergence Delirium (PAED) scale .The time to remove the laryngeal mask airway ,the time to be discharged from the post-anesthesia care unit (PACU) ,FLACC and Ramsey scores ,post-operative nausea and vomiting were recorded and considered .Results Compared with the control group ,the incidence of emergence agitation and PAED scales of D2 and D3 group were significantly lower than it (P < 0 .05) .Compared with the control group , FLACC scores of D2 and D3 group were lower than it(P< 0 .05) .At the same time ,Ramsey scores of D2 and D3 were higher than that of the control group(P < 0 .05) .Moreover ,Ramsey score of D3 was higher than D2(P < 0 .05) .The time span of being dis-charged from the PACU of D3 was significantly longer than that of the other groups(P< 0 .05) .Conclusion Dezocine of 0 .05 mg/kg and 0 .10 mg/kg both can reduce the incidence of emergence agitation effectively ,and there is no significant difference between the effect of the two doses .However ,the dose of 0 .05 mg/kg has a better performance in the time span for being discharged from the PACU .

Objective:To explore the effect of stage target intervention on mental state, quality of life and prognosis of spontaneous cerebral hemorrhage, so as to provide reference for improving the quality of life and prognosis of patients with spontaneous cerebral hemorrhage.Methods:A total of 261 patients with spontaneous cerebral hemorrhage from June 2017 to June 2019 in Beijing Union Hospital were selected as the research subjects. Patients were divided into the observation group (131 cases) and the control group (130 cases) by the random number table method. The control group was treated with routine nursing intervention, and the observation group applied stage target intervention based on the control group. The psychological state, quality of life and prognosis of the two groups were evaluated by Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), modified Rankin Scale (mRS), Stroke Specific Quality of Life scale (SS-QOL).Results:There were no significant differences in SAS, SDS, mRS, SS-QOL before intervention between the two groups ( P >0.05) . After intervention, the scores of energy, family role, language, activity, emotion, personality, self-care ability, social role, upper limb function, work / labor and total scores of SS-QOL in the two groups were all increased ( P < 0.05), and the increase of energy, family role, language, activity, emotion, personality, self-care ability, social role, upper limb function, work / labor and total scores of SS-QOL in the observation group were higher than those in the control group, and the differences were statistically significant ( P < 0.05). After intervention, the scores of SAS, SDS and mRS were (42.07±4.14), (43.09±4.79), (3.06±0.42) points in the observation group and (51.83±4.65), (54.82±4.92), (3.57±0.50) points in the control group, and the differences were statistically significant ( t values were 17.912, 19.516, 8.925, P < 0.05). Conclusions:Stage target intervention can improve the anxiety and depression of patients with spontaneous cerebral hemorrhage, improve the quality of life, and reduce the incidence of poor prognosis.

Objective To investigate the effect of dezocine on emergence agitation (EA) during recovery from sevoflurane-based anesthesia in children.Methods Ninety ASA Ⅰ or Ⅱ children,aged 3-6 yr,weighing 14-31 kg,were randomized into 3 groups (n =30 each):fentanyl group (group F),dezocine group (group D)and control group (group C).Anesthesia was induced with inhalation of 8 ％ sevoflurane and iv injection of atracurium 0.5 mg/kg and remifentanil 1 μg/kg and maintained with inhalation of 2％-3 ％ sevoflurane and infusion of remifentanil at 0.1-1.0 μg· kg-1 · min-1.In groups F,D and C,fentanyl 2 μg/kg,dezocine 0.05 mg/kg and the equal volume of normal saline were injected intravenously 10 min before the end of surgery,respectively,and inhalation of sevoflurane was stopped at the end of operation.The extubation time and length of stay in the postanesthesia care unit (PACU) were recorded.Agitation and the duration were recorded when the children were in PACU.The degree of EA was assessed using the Pediatric Anesthesia Emergence Delirium (PAED) scale.Pain was evaluated using the Children' s Hospital of Eastern Ontario Pain Scale (CHEOPS) and sedation was measured with Ramsay score.The complications such as respiratory depression,postoperative nausea and vomiting were recorded within 24 h after operation.Results Compared with group C,the incidence of EA and PAED scores were significantly decreased and the duration of EA was shortened in groups F and D,CHEOPS scores were decreased at each time point after operation and Ramsay scores were increased at T1 in group F,and CHEOPS scores were decreased and Ramsay scores were increased at each time point after operation in group D (P ＜ 0.05).Compared with group F,the incidence of EA and PAED scores were significantly decreased,CHEOPS scores were decreased at each time point after operation,and Ramsay scores were increased at T2 (P ＜ 0.05),and no significant change was found in the duration of EA in group D (P ＞ 0.05).There was no significant difference in the extubation time and length of stay in the PACU between the three groups (P ＞ 0.05).Conclusion Dezocine 0.05 mg/kg can safely and effectively prevent EA during recovery from sevoflurane-based anesthesia in children and produces better efficacy than fentanyl.

Methods 10 nurses (to carry on laryngoscope intubation theory, and had certain study period practice) were chosen in group A and 10 clinical anaesthetize doctors (to be possible correctly used visible laryngoscopes) were chosen in group B, two groups used the visible laryngoscope on the same model person body inserted the tube, computer monitor software recorded results. Results The impulse force was (25.57±3.37) N·s and insert tube time was (25.3±3.3) s in group A which were higher than (16.47±2.99) N·s and (16.2±3.0) s in group B (t=2.550 and 2.207, P<0.05). The average forces in group A and group B were (0.87±0.62) N and (0.64±0.30) N, and peak forces were (3.05±0.95) N and (2.06±0.48) N, there was no remarkable difference between the two groups (P>0.05). Conclusions There is no statistics difference forces applied to the oropharyngeal organization between nurses and anaesthesiologists using visible laryngoscope intubation, and visible laryngoscope intubation technique is easy to learn and it is feasible by the nurse to master the technology and applied to anesthesia intubation care and emergency care.

Objective To evaluate the efficacy and safety of Qingpeng ointment for the treatment of localized dermatitis and eczema in children.Methods Sixty-eight outpatient children with localized dermatitis or eczema were included in this study.All the patients were topically treated by Qingpeng ointment twice daily for a week,which was agreed by their patients.The efficacy was evaluated after the end of the treatment by lesion scores,and adverse reactions during the treatment were recorded.Results Of the 68 patients,61 completed the trial,7 withdrew from the trial because of worsened lesions,unfavorable effects and distrust of this drug.The total response rate was 81.4％ (31/51) in patients treated with Qingpeng ointment alone.Irritant reaction occured in only one case,but did not influence the treatment.Conclusion Qingpeng ointment displays a favorable efficacy and safety in the treatment of localized dermatitis and eczema in children.

Objective To evaluate the reliability of ultrasonography used to guide the selection of uncuffed endotracheal tube (ETT) size for pediatric patients.Methods Eighty pediatric patients requiring endotracheal intubation for elective surgery under general anesthesia,aged 2-6 yr,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,were randomized into 2 groups (n=40 each) using a random number table:control group and ultrasonography group.In control group,the internal diameter of an uncuffed ETT was determined according to age-based formulas.In ultrasonography group,the outer diameter of an uncuffed ETT was determined according to the transverse diameter of the subglottic airway at the level of the cricoids cartilage measured by ultrasonography.The air leak test was performed after intubation,and either a larger or a smaller size of ETT selected was considered as a failure of intubation.The failure of intubation and postoperative complications related to intubation were recorded.Results Compared with control group,the total failure rate of intubation and failure rate due to the smaller size of ETT selected were significantly decreased in ultrasonography group (P＜0.01).There was no significant difference in the incidence of intubation-related complications between the two groups (P＞0.05).Conclusion Ultrasonogra-phy can be used to guide the selection of ETT size for pediatric patients.

OBJECTIVE To analyze the monitoring performance and testing efficacy and reliability of standardized disposable B-D test pack and standard linen test pack,and summarize the corrective actions based on failure analyses for future reference.METHODS The two different test packs were employed to evaluate the vacuum performance of dynamic air removal sterilizer.RESULTS We enrolled 400 standardized disposable B-D test packs and standard linen test packs respectively.The disposable pack failed 4 cases with the success ratio 99%,while the linen pack failed 30 cases with the success ratio 92.5%.CONCLUSIONS The poor conformity of hand-made linen test pack,variation of steam pressure,sterilizer failure,and unprofessionalism of sterilizer operator contribute as main failure causes in B-D test.Standardized disposable B-D test pack can decrease subjective factors significantly,and the test results are more reliable and standardized.

Objective:To evaluate the diagnostic value of digital breast tomosynthesis (DBT) and digital mammography (DM) for radial lesions.Methods:The data of 76 patients (78 lesions) with radial lesions confirmed by operation and pathology on DBT between December 2016 and May 2020 in the Affiliated Hospital of Qingdao University were analyzed retrospectively. Taking pathological results as the gold standard, 78 lesions were divided into benign radial lesions ( n=46) and malignant radial lesions ( n=32), and their DBT features were compared. According to the standard of breast imaging report and data system (BI-RADS), the wheel-spoke structure, central density, overall size, central size and surrounding burr length of the two groups of radial lesions were compared on DBT. Results:The detection rates of DM and DBT for 78 radial lesions were 59.0% (46/78) and 100% (78/78), the difference had statistically significant ( P<0.05). The diagnostic accuracy rates of DM and DBT for 78 radial lesions was 65.2% (30/46) and 74.4% (58/78), the difference had no statistically significant ( P>0.05). The sensitivity, specificity, misdiagnosis rates, missed diagnosis rates of DM and DBT in the diagnosis of malignant radial lesions were 64.3%(18/28) and 84.4%(27/32), 66.7% (12/18) and 67.4%(31/46), 33.3%(6/18) and 32.6%(15/46), 35.7%(10/28) and 15.6%(5/32), respectively. The difference was not statistically significant ( P>0.05). There were significant differences in the overall size of lesions [18.0 (14.9, 29.2) mm, 26.5 (20.2, 34.9) mm], central size [3.5 (2.5, 4.5) mm, 4.5 (3.5, 5.5) mm] and peripheral burr length [(11±6) mm, (13±4) mm] between benign and malignant radial lesions on DBT ( P<0.05). When the central size of the lesion was 5 mm, there was significant difference in the distribution of benign and malignant radial lesions ( P<0.05), and when the overall size of the lesion was 2 cm, there was significant difference in the distribution of benign and malignant radial lesions ( P<0.05). Conclusion:DBT can improve the detection and diagnosis accuracy of radial lesions, and provide an important basis for clinicians to make surgical treatment decisions.
