The study aim was to identify and analyze intramuscular electrically sensitive points. Electrically sensitive points are herein defined as positions, which allow muscles stimulation with a minimum possible fatigue for a maximum amount of time. A multichannel array electrode was used which could be interesting to retain the function of larynx muscle after paralysis. Eight array electrodes were implanted in the triceps brachii muscle of four rats. While being under anesthesia, the animals were intramuscularly stimulated at 16 different positions...

Coronary vasospasm(CV)can cause severe arrhythmia and myocardial infarction(MI). Intraoperative CV is not limited to cardiac surgery alone. We report the case of a patient who experienced cardiac arrest after the induction of general anesthesia, but did not demonstrate any abnormalities on preoperative examination. The patient was a 60-year-old man with no history of ischemic heart disease, with NASCET 80% asymptomatic left internal carotid stenosis(ICS). We decided to perform carotid endarterectomy(CEA). Preoperative stress myocardial scintigraphy did not reveal decreased local uptake...

Sjogren's syndrome is one of the most common autoimmune disorders and has a female predominance. Maternal circulating autoantibodies such as anti-Ro/SSA and anti-La/SSB antibodies can cause congenital heart block of fetus, and in severe case, emergency pacemaker implantation may be needed for neonate. Therefore, it is very important to understand maternal and fetal condition and pay attention to the status of the neonate during delivery. In this paper, we present a case of patient with Sjogren's syndrome who underwent cesarean section under spinal anesthesia...

We aimed to determine how age-associated changes in mechanisms extrinsic and intrinsic to pacemaker cells relate to basal beating interval variability (BIV) reduction in vivo. Beating intervals (BIs) were measured in aged (23-25 months) and adult (3-4 months) C57BL/6 male mice (i) via ECG in vivo during light anesthesia in the basal state, or in the presence of 0.5 mg mL(-1) atropine + 1 mg mL(-1) propranolol (in vivo intrinsic conditions), and (ii) via a surface electrogram, in intact isolated pacemaker tissue...

UNLABELLED: An 85-year-old man was referred to our hospital with a pacemaker pocket infection. A permanent pacemaker had been implanted via the right subclavian vein. The pacemaker and pacing leads were removed and a temporary pacemaker was implanted. After vancomycin treatment for 4 weeks, pacemaker implantation via the right external iliac vein was performed under local anesthesia because of left subclavian vein occlusion, infection of the right pocket, and difficulty with epicardial lead insertion...

A 60-year-old woman posted for percutaneous nephrolithotomy with ureterolithotripsy was found to have a history of hypertension and ischemic heart disease from past 6 months on regular treatment. Pulse rate was irregularly irregular in a range of 56-60/min, unresponsive to atropine, with a sinus pause on the electrocardiogram. Although the patient was asymptomatic, anticipating unmasking of the sick sinus syndrome during general anesthesia in the prone position, a temporary pacemaker was implanted at right ventricular outflow tract (RVOT) septum before the scheduled surgery...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is becoming a valuable alternative to surgical aortic valve replacement in patients with severe aortic stenosis that are at high surgical risk or deemed inoperable. The optimal anesthesia technique for TAVI is still undecided. We performed a systematic review and metaanalysis to compare the safety of locoregional anesthesia (LRA) with or without conscious sedation and general anesthesia (GA) for the TAVI-procedure. METHODS: We searched PUBMED, MEDLINE, EMBASE and the Cochrane central register of controlled trials from January 1st 2002 to February 15th 2015...

Power supply for medical implantable devices (i.e. pacemaker) always challenges not only the surgery but also the battery technology. Here, we report a strategy for energy harvesting from the heart motion by using ultra-flexible piezoelectric device based on lead zirconate titanate (PZT) ceramics that has most excellent piezoelectricity in commercial materials, without any burden or damage to hearts. Experimental swine are selected for in vivo test with different settings, i.e. opened chest, close chest and awake from anesthesia, to simulate the scenario of application in body due to their hearts similar to human...

A 79-year-old man with aortic stenosis (AS) was scheduled for right middle lobectomy under general anesthesia. AS is a significant risk factor for the development of cardiac complications after noncardiac surgery. Anesthetic management adjusting left ventricular preload and coload, and keeping sinus rhythm was successful with no complications. But after moving back to the intensive care unit after surgery, ECG showed paroxysmal complete atrioventricular blocks and we inserted a temporary transvenous pacemaker catheter...

INTRODUCTION: The proportion of patients who die during or after surgery, otherwise known as the perioperative mortality rate (POMR), is a credible indicator of the safety and quality of operative care. Its accuracy and usefulness as a metric, however, particularly one that enables valid comparisons over time or between jurisdictions, has been limited by lack of a standardized approach to measurement and calculation, poor understanding of when in relation to surgery it is best measured, and whether risk-adjustment is needed...

There is currently no consensus on the duration of hospitalization required after transfemoral transcatheter aortic valve implantation (TAVI). We report the feasibility and safety of early discharge after TAVI with the Edwards SAPIEN-XT prosthesis. From 2009 to 2013, 337 patients underwent transfemoral TAVI with the Edwards SAPIEN-XT prosthesis using local anesthesia and were discharged home either early (≤3 days, Early Discharge group, n = 121) or after 3 days (Late Discharge group, n = 216). The primary end point of the study combined death and rehospitalization from discharge to 30-day follow-up...
