Chinese Journal of Health Policy 2014;(9):68-71
Objective:To investigate the use of antibacterial drugs during the perioperative period of a cesarean section and observe the differences before and after antibacterial drug remediation. Methods:1 569 cesarean cases from 2010 to 2012 were investigated, and the use of antibacterial drugs, drug categories, drug combinations, medical expenses, and so on was statistically analyzed with the use of the statistical software SPSS13. 0. Results:The rate of antibacterial drug usage within the 1 569 cesarean cases was 100%;for pre-operative antibacterial drug remediation, azithromycin, cefathiamidine, and ornidazole were the top three, while the top three antibacterial drugs for post-oper-ative remediation were arecefathiamidine, cefuroxime, and clindamycin. There was no significant difference between the two groups of incision infections, and the rate for combined use of drugs dropped. The analysis of drug costs is of statistical significance. Conclusion:The analysis of antibacterial drug remediation is useful for the rational use of anti-bacterial drugs and a reduction of costs.

ObjectivePresent treatment in plastic surgery on giant congenital melanocytic nevus has always been a tough practice because it is difficult to achieve balance between effects and costs of treatment.This paper aimed to explore the concrete procedure of tangential excision and dermabrasion in treatment of adult giant congenital melanocytic nevus. Methods Taking into consideration pathological examination results before surgery,diseased regions,psychological expectancy and other factors,we used a humby knife or globe grinding head to remove giant congenital relanocytic nevus by wiping off the surface of it in 10 cases.After operation,the operated area of the skin underwent a process of healing in a moisturized state.In each case,surgical procedure was carried out by 1 2 sta ges,with the interval period ranges from 3 months to 6 months.ResultsOne to 3 years follow-ups showed that among those cases,5 cases obtained good results in which skin color of surgical area turned to normal and pathological examination showed that nevus cells disappeared,4 cases achieved improvement,and 1 case was relapsed.ConclusionsThe two alternative methods for treatment of giant congenital melanocytic nevus,either tangential excision or dermabrasion,with combination of pathological examination results,diseased regions,and psychological expectancy should be taken into consideration,which can remain a maximum balance between effects and costs of treatments.Tangential excision and dermabrasion are effective in some cases of giant congenital nevus where traditional methods do not work,or in order to reduce the cost of body appearance in treatment.Therefore,these two methods deserve to be adopted extensively in clinical therapy.But it still needs further accumulation of experience in practice and longer period of follow-up after operation.

Objective To explore independent risk factors of ventilator associated pneumonia (VAP) on severe craniocerebral injury patients, and propose nursing intervention measures to reduce occurrence of VAP. Methods A retrospective analysis was conducted on 73 severe craniocerebral injury patients with VAP postoperatively from January 2013 to June 2015, and 80 severe craniocerebral injury patients underwent mechanical ventilation without VAP postoperatively at the same time were selected as the control group. Through literature review, questionnaire was designed to collect potential impact factors of VAP in both two groups, the single factor analysis and Logistic regression analysis were applied to explore the VAP independent risk factors, and nursing intervention countermeasures were proposed to improve VAP clinical prevention. Results VAP incidence rate of severe craniocerebral injury patients postoperatively was 23.0%(73/317) , from which 81 strains were detected, the first three strains of strain spectrum were Klebsiella pneumonia (21.0% ), Bauman Acinetobacter (17.3% ) and pseudomonas aeruginosa bacteria (14.8% ). Single factor analysis showed there were significant differences on composition of two groups in age, preoperative Glasgow Coma Scale (GCS) score, operation times, artificial airway type, postoperative mechanical ventilation time, daily airway humidification frequency, daily sputum suction frequency compound injury, daily oral care times (χ2=1.809-11.936, P < 0.01 or 0.05). Logistic regression models showed duration of mechanical ventilation (OR≥7d=3.013; OR≥14d=3.695), secondary surgery (OR =3.111) , preoperative GCS score (OR =2.989), daily airway humidification frequence (OR =2.280), age (OR=2.237) had remarkable influence on occurrence of postoperative VAP (P<0.01 or 0.05). Conclusions The incidence rate of VAP in severe craniocerebral injury patients is higher, age, mechanical ventilation duration, preoperative GCS score, airway humidification degree, second surgery are the independent risk factors of VAP.

Objective To analyze the risk factors for traumatic cerebral venous sinus occlusion (CVSO)and to investigate the strategies of early diagnosis of traumatic CVSO. Methods The clinical data of 212 patients with moderate to severe closed traumatic brain injury from January 2012 to December 2015 were analyzed retrospectively. Logistic regression analysis was used to evaluate the risk factors for traumatic CVSO. Results Of the 212 patients with traumatic brain injury, 16.5%(35/212) patients had CVSO. Ten patients had CVSO of thrombotic type (typeⅠ), 16 patients had CVSO of compression type (typeⅡ), and 9 patients had CVSO of mixed type (typeⅢ). Logistic regression analysis showed that skull fracture (OR = 8.141; 95%CI: 3.224-20.840) and epidural hematoma of crossing venous sinus (OR = 3.179; 95%CI: 1.470-7.037) were the risk factors for CVSO, and the former was more significantly correlated with CVSO. Female gender was the risk factor for CVSO typeⅠ(OR =10.425; 95%CI: 1.831-30.053), epidural hematoma of crossing venous sinus was the risk factor for CVSO typeⅡ(OR = 5.766; 95%CI: 1.885-18.197), and skull fracture, epidural hematoma of crossing venous sinus, and the previous history of vein thrombosis was the risk factors for CVSO type Ⅲ(OR =18.005, 4.596, 11.394; 95%CI: 2.021-58.836, 1.144-19.525, 1.436-46.558). Conclusions In the early diagnosis of traumatic CVSO, the crossing venous sinus fracture line and epidural hematoma should be given attention. Attention should be paid to the history of venous thrombosis. MR venography and CT venography contributes to early diagnosis of CVSO.

Objective To access the changes in blood gases and electrolytes during anaphylactic shock induced by Echinococcus granulosus (EG) in sheep.Methods Fifteen healthy sheep of either sex weighing 31.2 ? 3.5 kg were repeatedly infected with EG for six months. The infected sheep were anesthetized with intramuscular thiopental 20mg?kg-1 and ketamine 15 mg?kg-1. The animals were breathing spontaneously and placed on the left side. ECG (lead Ⅱ) was monitored. Swan-Ganz catheter was placed via right internal jugular vein for hemodynamic monitoring. Anaphylactic shock was induced with antigen prepared from fluid in EG capsules. Blood samples were taken from right internal carotid artery before shock (T0) and 3.5 min (T1 ), 8 min (T2), 15 min (T3), 30 min (T4) and 60 min (T5 ) after shock was induced for determination of blood Na+ , K+ , Hct, Hb, pH, PaO2 , PaGO2 and HCO3-. Shock was confirmed by hypotension (MAP decreased by 30%), tachypnea, dyspnea, agitation and pupil dilation. Results Three sheep did not develop shock and two sheep died of severe shock within 10 min after iv antigen challenge. Blood K+ significantly increased at T1 and T2 after antigen challenge and then gradually returned to baseline value at T5 . PaO2 decreased, PaGO2 increased and pH deceased after challenge. Hct and Hb also increased significantly after challenge. Conclusion There are significant changes in blood gas and electrolytes indicated by hyperkalemia, acidosis and hypoxemia during anaphylactic shock induced by EG.
