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.
目的:比较常规鼻胃管置入法与鼻咽部局部喷雾麻醉后置胃管法对喉癌患者的影响。方法:将需要安置胃管的100例患者随机分成两组,每组50例。实验组行鼻咽部喷雾麻醉,对照组按常规操作,比较两组患者流泪、恶心、呕吐、咳嗽反应,一次成功率及插管所需要时间、插入中暂停次数。结果:实验组一次成功率高,患者反应轻,插管所需时间有显著差异。结论:常规置胃管常因病员难受而中途暂停置管,实验组置胃管前先作鼻咽部局部喷雾麻醉,可明显减轻患者的痛苦,提高插胃管的一次成功率,插管过程中因病员难受暂停次数也明显减少,使临床护理工作时间缩短,对临床护理工作有积极意义。
Abstract: Objective To investigate the feasibility of the diagnosis and treatment of pleurallung diseases by minithoracotomy and videoassisted thoracic surgery(VATS) under local anesthesia. Methods From February 2002 to March 2005,30 cases were performed by thoracotomy under local anesthesia,which were divided into two groups including minithoracotomy group and VATS group according to the different approaches; inithoracotomy group was used just for the biopsy of thicken pleura and diffuse pulmonary diseases on the state of open pneumothorax, and VATS group was for the diagnosis and treatment of malignant effusion and recurrent pneumothorax on the state of closed pneumothorax,all of them were ompleted under local anesthesia. Results Minithoracotomy group: biopsy of pleura were performed on 13 cases, 10 cases of which has been diagnosed with metastasis, one case was amyloidosis of pleura, two cases were proliferation of pleura.Three cases on diffuse pulmonary diseases were done for biopsy, 2 of which were pulmonary interstitial fibrosis, 1 of which was pulmonary tuberculosis (type Ⅱ). VATS group: Except one was converted to general anesthesia and minithoracotomy to resect the lesion due to heavy pleural adhesion, other patients who had thicken pleura and diffuse pulmonary diseases were performed operation for biopsy, bullarectomy was done on recurrent pneumothorax,and pleurodesis was done on ntractable pleuaral effusion under local anesthesia. 4 cases on pleural effusion were done by diagnostic thoracoscope under local anesthesia, 1 of which was liverrelated pleural effusion. 14 cases has been done by remedial thoracoscope, 8 cases of which malignant pleural effusion were done for pleurodesis, the other cases which have recurrent pneumothorax were given bullaectomy and pleurodesis. Spontaneous breathing and hemodynamics was maintained well during the operation. There was neither severe complication nor mortality in two groups. Conclusion Videoassisted thoracoscopic resection of peripheral pulmonary nodule and biopsy of pleura through minithoracotomy can be performed safely under local anesthesia. The novel approach will be the cost-effective procedure for management of pulmonary nodules in the present time.
目的 探讨在局部麻醉下行痔上黏膜环形切除钉合术(procedure for prolapse and hemorrhoids,PPH)治疗重度内痔的可行性及临床应用价值。方法 笔者所在医院科室从2005年起对32例Ⅲ度及Ⅳ度脱垂性内痔(含1例混合痔)患者均采用苯巴比妥+氢溴酸东莨菪碱+利多卡因肛管直肠环形局部浸润麻醉行PPH术,对其麻醉效果、手术时间、术中及术后疼痛、尿潴留、术后感染、肛门狭窄、住院时间、治疗满意度等进行分析。结果 32例患者均顺利完成手术,有1例术中改行低位连续硬膜外麻醉,1例辅加镇静剂及镇痛剂。术后28例对疼痛能耐受,4例需镇痛药物;1例患者有肛门坠胀感;所有患者伤口均一期愈合,无尿潴留、术后感染、出血、肛门狭窄等并发症发生;31例对疗效满意,有1例感肛门坠胀,行温水坐浴及痔疮膏纳肛治疗1周后缓解。住院时间3~6d,平均4d。32例患者均进行有效随访,随访时间2~4个月,平均3个月,无大便失禁或复发,肛门控便能力均可。结论 局部麻醉下行PPH术治疗重度内痔是一种安全可行的手术方法,麻醉操作护理简单,疗效确切,术后并发症少,术后恢复快,并可减少医疗费用。
目的 探讨局部麻醉(以下简称局麻)腹股沟疝无张力修补术在基层医院的应用价值。方法 分析内蒙古医学院附属人民医院2010年10月至2011年12月期间242例行局麻腹股沟疝修补手术患者的临床资料。结果 除1例因过度紧张而停止手术外,其余手术顺利。平均手术时间50min,所有患者术后0.5~4h (平均2h) 均能下床活动,切口疼痛时间0.5~1d。无一例发生尿潴留;12例患者术后阴囊轻-中度水肿,切口感染1例。全部病例术后观察1~2d出院。门诊随访2~15个月(平均8个月),复发2例。结论 局麻下腹股沟疝无张力修补术安全、疼痛轻微、禁忌证少、复发率及费用低,值得在基层医院推广。
Objective To investigate the most suitable anaesthesia method for the tension-free herniorrhaphy.Methods A total of 422 unilateral inguinal hernia cases from 2002 to 2005 were collected and randomly divided into the local anaesthesia group and epidural anaesthesia group. Observation indices and some relative data, such as operative duration, date of ambulation, date of foodintake, length of hospital stay, operation-correlated complications, anaesthesia complications, usage rate of ancillary drug, satisfactory rate for anesthesia, cost of hospitalization, were included and recorded in the questionnaire, and all the patients who took the tension-free herniorrhaphy were asked to answer it as the follow-up research. Results It was found that the occurrence of postoperative anaesthetic complications, the cost of hospitalization, length of stay of local anaesthesia group were significantly less than those of epidural anaesthesia group, and the date of moving and the date of foodintake were also significantly earlier than those of the other group (P<0.05). However, there was no significant difference of operative duration, postoperative recovery situation and the satisfactory rate between two groups (P>0.05).Conclusion The local anaesthesia is suitable for most of the tension-free herniorrhaphy, and it may be used as the conventional anaesthetic method.
