相同剂量不同浓度的罗哌卡因用于腰丛坐骨神经联合阻滞的临床研究 总被引:1,自引:0,他引:1
目的:观察相同剂量不同浓度的罗哌卡因用于腰丛坐骨神经联合阻滞的临床效果。方法:择期行单侧下肢手术的患者90例,年龄18~65岁,ASAⅠ或Ⅱ级,随机分为3组(n=30):A组给予0.3%的罗哌卡因腰丛36mL、坐骨神经24mL,B组给予0.36%的罗哌卡因腰丛30mL、坐骨神经24mL,C组给予0.4%罗哌卡因腰丛27mL、坐骨神经18mL。分别于给药后2、5、10、15、20、25、30、35min测定下肢的感觉、运动评分以及感觉阻滞的时间和运动阻滞的时间。结果:三组患者阻滞起效时间无明显差别,高容量组完全阻滞的持续时间短于低容量组;高容量低浓度组患者完全阻滞率高于低容量组,但达到完全阻滞时间长于低容量组。结论:在剂量相同时罗哌卡因的浓度和容量会影响腰丛和坐骨神经的阻滞效果;高容量罗哌卡因更有利于达到良好的感觉阻滞。 相似文献

A 34-year-old man with ankylosing spondylitis was admitted to the hospital because of syncopal attacks and heart block. Standard ECG, telemetry and an invasive electrophysiologic examination demonstrated right bundle branch block with left anterior fascicular block, sinus node dysfunction with spontaneous slowing of the sinus rate and, as a result, complete infrahisian atrioventricular block in the remaining fascicle at sinus rates below 57 beats per minute. Infrequent supraventricular extrasystoles and abruptly terminated atrial pacing led to the same result. Atrioventricular conduction resumed after three-to-four blocked atrial impulses with successively increasing rate. Pacemaker treatment provided complete symptomatic relief. 相似文献

Abstract: Pain in patients with cancer can be refractory to pharmacological treatment or intolerable side effects of pharmacological treatment may seriously disturb patients’ quality of life. Specific interventional pain management techniques can be an effective alternative for those patients. The appropriate application of these interventional techniques provides better pain control, allows the reduction of analgesics and hence improves quality of life. Until recently, the majority of these techniques are considered to be a fourth consecutive step following the World Health Organization’s pain treatment ladder. However, in cancer patients, earlier application of interventional pain management techniques can be recommended even before considering the use of strong opioids. Epidural and intrathecal medication administration allow the reduction of the daily oral or transdermal opioid dose, while maintaining or even improving the pain relief and reducing the side effects. Cervical cordotomy may be considered for patients suffering with unilateral pain at the level below the dermatome C5. This technique should only be applied in patients with a life expectancy of less than 1 year. Plexus coeliacus block or nervus splanchnicus block are recommended for the management of upper abdominal pain due to cancer. Pelvic pain due to cancer can be managed with plexus hypogastricus block and the saddle or lower end block may be a last resort for patients suffering with perineal pain. Back pain due to vertebral compression fractures with or without pathological tumor invasion may be managed with percutaneous vertebroplasty or kyphoplasty. All these interventional techniques should be a part of multidisciplinary patient program. 相似文献

Purkinje and ventricular myocardial fibers are thought to be more sensitive to hyperkalemia than sinoatrial and atrioventricular (AV) nodes, although complete AV block due to hyperkalemia can occur. We describe a case in which hyperkalemia in a patient affected by renal failure is responsible for complete AV block without QRS complex prolongation. Temporary endoventricular pacing was essential in restoration of adequate renal blood flow and excretion of exceeding serum potassium with subsequent normalization of AV conduction. 相似文献

We report the case of an 80-year-old man with a preexistent right bundle branch block (RBBB) who underwent dobutamine stress echocardiography. As the sinus cycle length gradually decreased during the stress test, he first developed a 2:1 RBBB pattern alternating with beats showing normal conduction and then an alternating 2:1 less complete and more complete RBBB pattern. An elucidation of the potential mechanism of the latter very rare phenomenon is provided. 相似文献

Twenty six patients (aged 46-80, mean age 64) with bifascicular block in the presence of prolonged H-V interval (trifascicular block), were followed for an average of 31 months after inserting an R-wave inhibited pacemaker (PM) because of syncope and/or dizzy attacks. The underlying rhythm was evaluated at 4-6-month intervals by three different techniques: 1) 12-lead ECG when intrinsic patient rate was faster than PM rate; 2) abrupt PM inhibition (APMI) by the rapid chest-wall stimulation technique, and 3) progressive PM inhibition (PPMI) using a programmed chest-wall stimulation technique capable of decreasing the PM rate gradually to 30 beats/min before complete PM inhibition. In addition, the PPMI allowed the underlying rhythm to be induced and sustained and properly evaluated without any discomfort to the patient. Following PM insertion, 4 patients (15%) developed complete heart block after a mean follow-up of 43 months, and one patient (4%) developed 2nd degree 2:1 A-V block (VX) after 83 months. The P-R interval increased in 5 patients (19%) and decreased in 2 (8%). No change of A-V conduction was found in 9 patients (34%). Three patients developed low atrial rhythm, atrial flutter and atrial fibrillation, respectively (12%). After PM insertion 2 patients still complained of dizziness. None reported syncope. Two patients died during follow-up, both of congestive heart failure (8%). By detection of intrinsic rhythm it was recognized that a long symptomatic paroxysmal phase may precede the development of chronic complete A-V block. Therefore, the insertion of a permanent PM is recommended in patients with unexplained neurologic symptoms and trifascicular disease, without waiting for documented episodes of complete A-V block. 相似文献

A 54-year-old man with normal atrioventricuiar (AV) conduction at rest gave a 4-year history of presyncope during exercise. Treadmill testing showed exercise induced AV block. Electrophysiological study demonstrated rate dependent infranodal AV block and abnormal refractory period of the His-Purkinje system. The gap phenomenon in AV conduction occurred during the programmed stimulation. Supernormal conduction could be considered as the mechanism of the gap phenomenon in this patient. 相似文献

Background: Syncope due to episodes of paroxysmal atrioventricular (AV) block, defined as transient advanced second or third-degree block, is rarely reported in pediatric patients without congenital heart disease.
Methods: We reviewed our institutional arrhythmia database from January 1988 to January 2007 to identify all patients less than 18 years of age with normal cardiac anatomy and episodes of syncope associated with paroxysmal AV block. Demographic and clinical information was collected.
Results: Six patients were identified ( Table I ). Five of the six patients were female, with an average age of 9.3 ± 4.4 years. Patients had episodes of syncope for an average of 5.6 ± 3.3 years prior to diagnosis. All patients had normal physical examinations, electrocardiograms, and echocardiograms. None were on medications known to interfere with AV nodal function, and laboratory evaluation including Lyme titers were negative. Five of the six patients' episodes were atypical for vasovagal syncope (except patient 6). All patients had documented paroxysmal AV block on either inpatient cardiac monitor, Holter monitor, or event recorder at the time of syncope. There was maintenance or acceleration of the sinus rate during episodes of syncope in all patients (mean atrial rate 107 ± 37 bpm). All six patients had permanent transvenous pacemakers implanted with resolution of symptoms over a mean follow-up of 5.2 ± 6.3 years.
