Objective To assess efficacy of mepivacaine on local anesthesia in dentistry and oral surgery and its safety. Methods Parallel group, stratified randomization, double blinded, muti-center clinical trial was designed. Two percent lidocaine with adrenaline in same cartridge was as control. Healthy patients with deep decay, pulpitis needed operative dentistry, or indication for extraction of the teeth, which located in the maxilla or front part of the mandible were included. Results Except 17 cases, 127 patients fulfilled inclusion criteria: 66 in treatment group and 61 in control group, dental filling for 60 and extraction for 67 cases, male 55 and female 72, average at 38.84 + 12.06 years. Submucous infiltration of 1.5 ml mepivacaine at labial or buccal side of the alveolar process produced onset of anesthesia in the median of 60 seconds which was same as that of lidocaine, anesthesia duration for 146.7 minutes with the median of 125 minutes, permitting painless filling or extractions. In the treatment group 81.82% freed of pain, while 15.15% had slight pain but received no extra local anesthetic for implementation of the treatment procedures, making the successful rate of 96.97%. In the mepivacaine group, 13.64% of the cases had transient elevation of the systolic pressure to the level of 145-162 mmHg, 8.33% diastolic pressure to the level of 91-93 mmHg. Only one case had transient palpitation in half minute after one minute injection of the drug with no medical care needed. All the cardiovascular reactions might result from adrenaline containing in the injections. Conclusion Mepivacaine is an effective, safe and reliable anesthetic agent for dentistry and oral surgery.
Backgroud Chronic hepatitis is the major infectious disease of liver. There is no effective drug for it up to now. Clinical trials have showed that glycyrrhizin have potentional effective for chronic hepatitis. Objective To evaluate the effectiveness, safety and economics of glycyrrhizin for chronic hepatitis B and C. Search strategy The search terms include glycyrrhizin and its products’ name, chronic hepatitis and chronic carrier status. The thais registers of the Cochrane Hepato-Biliary Group, the Cochrane Complementary Medicine Field, and the central database of The Cochrane Library as well as MEDLINE, EMBASE and Chinese Biomedical CD Database were searched from their date of inception onward. And the free Internet search was operated to find ongoing and unpublished researches. Twenty Chinese medical journals and relevant academic conference proceedings have been searched by manual method. The reference lists of identified documents were checked as the complementary search. Inclusion criteria All randomized trials that tested glycryyhizin for chronic hepatitis B virus or hepatitis C virus infection were included in this review. Method of the review According to the principle of Cochrane systematic review, selection of thai for inclusion, assessment of methodological quality, data extraction and data syntheses were conducted by two reviewers.
Background Hepatitis B is one of the major infectious diseases of mankind, and up to now, there is no effective way to handle it. Recent clinical trials have shown the potential advantages of Kurorinone an extract of Chinese herb, in treament of chronic HBV infection. Objectives Systermically review the safety and efficacy of Kurorinone in treatment of chronic HBV infection. Search strategy With the searching terms including Kurorinone, its products’ name, hepatitis B and chronic carrier status, the trials registers of the Cochrane Hepato- Biliary Group, the Cochrane Complementary Medicine Field, and the central database of the Cochrane Library as well as MEDILINE, EMBASE and Chinese Biomedical CD Database were searched from their date of inception onward. 20 Chinese medical journals and relevant academic conference proceedings have been searched by hand. The reference lists of identified documents were checked as the complementary search. Inclusion Criteria All RCTs that tested Kurorinone for chronic HBV infection were included in this review. Method of the review According the demand of Cochrane systematic review, selection of trial for inclusion, assessment of methodological quality, data extraction and data syntheses would be conducted for each included trial.
Objective To provide evidence for establishing a medical risk precaution and monitoring system in China by evidence-based evaluation of the medical risk monitoring and precaution system in Canada, including the current situation and corresponding prevention measures. Method According to the unified search strategy made by our research group, we searched relevant databases and official or government websites. We included articles about medical risk management, medical error and patient safety in Canada. The included articles were classified and the quality was ranked. Results A total of 15 articles were included, among which 10 were official documents (about 2/3) and 5 described research methods (about 1/3), mainly involving medical risk management or evaluation, medical error and patient safety. In 2002, Canada established its National Steering Committee on Patient Safety (NSCPS) and proposed the suggestions to integrate health care resources accross the country, build a patient safety system, and established the Canada Patient Safety Institution (CPSI) to improve patient safety. Canada revised the patient safety management system, collected and issued related information, strengthened doctor-patient communication, developed continuous education for medical staff, practiced the best medical behavior and model and improved lawsuit procedures. These activities have achieved great progress in practice. Conclusions What have been done in Canada will provide a guide for us to establish scientific patient safety system and promote public awareness of patient safety.
To attend the Patient Safety Summit of UK Presidency of the EU 2005, learn and share ideas with each other, participate in discussing and developing the vision and mission as well as goals for patients for patient safety program, seek the common interest for further cooperation so as to help promote the activities on patient safety in healthcare in China.
Participating in patients for patient safety program will help place patients at the center of efforts to improve patient safety. This paper presented a brief introduction to patients for patient safety program and its significance and functions.
Informing is an initiative behavior of medical staff in their clinical practice. Besides, informing is a key principle of informed consent. The number of cases of infringing upon patient’s informed consent is increasing because of the underestimate or ignorance of the obligation of informing. This paper discusses the concept, significance, content, and procedure of informing as well as the relationship between informed consent and informing.
Objective To learn and analyse the current clinicians’ knowledge and attitudes towards patient safety, and to provide relevant evidence for future medical education. Method We conducted a survey on clinicians mainly in West China Hospital of Sichuan University with group random sampling method. We analysed the data on the clinicians’ knowledge and attitudes with SPSS softerware. Result Totally 300 questionnaires were distributed, of which 258 were completed adequately. The results showed the clinicians’ knowledge on patient safety was poor, however, the respcnse from the clinicians in Outpatient Department were better than those in Inpatient Department. The majority of the clinicians (above 95.00%) were willing to learn the knowledge of patient safety. Conclusion As the clinicians are willing to learn the knowledge of patient safety positively, it is necessary to integrate patient safety education into the current medical education curriculum.
Advancing patient safety is one of the most important strategies developed by WHO. The following paper outlined the main content, aims and goals of WHO the second global patient safety challenges “ Safe surgery saves lives” as well as discussed the importance of communication between surgeons and patients.
