Objectives: Unexpected systemic inflammatory response with high fever and increase in C-reactive protein (CRP) occurred frequently after endovascular abdominal aortic aneurysm repair (EVAR). This excessive inflammatory response affects the postoperative course. We evaluated the effects of steroid on the postoperative inflammatory response after EVAR. Methods: Steroid therapy, intravenous infusion of methylprednisolone 1000 mg just after the anesthesia induction, was started since December 2012. After induction of the steroid therapy, 25 patients underwent EVAR with steroid therapy (Group S)...

Anesthesia can affect respiratory, circulatory, and endocrine systems but is necessary for certain experimental procedures such as echocardiography and blood sampling in small animals. We have now investigated the effects of four types of anesthesia-pentobarbital (PENT), ketamine-xylazine (K/X), and low- or high-dose isoflurane (ISO)-on hemodynamics, cardiac function, and glucose and lipid metabolism in Sprague-Dawley rats. Aortic pressure, heart rate, and echocardiographic parameters were measured at various time points up to 45 min after the induction of anesthesia, and blood was then collected for measurement of parameters of glucose and lipid metabolism...

OBJECTIVE: Of the 230 million patients undergoing major surgical procedures every year, more than 1 million will die within 30 days. Thus, any nonsurgical interventions that help reduce perioperative mortality might save thousands of lives. The authors have updated a previous consensus process to identify all the nonsurgical interventions, supported by randomized evidence, that may help reduce perioperative mortality. DESIGN AND SETTING: A web-based international consensus conference...

Transcatheter aortic valve replacement (TAVR) is conventionally performed under general anesthesia (GA) allowing intraoperative transoesophageal echocardiogram imaging. We present our experience in patients having the procedure under local anesthesia (LA), who were subsequently transferred to a low dependency unit postprocedure, to assess safety and length of hospital stay. We retrospectively assessed all the transfemoral TAVR procedures conducted at our center from January 03, 2011. Of 216 patients, 145 had the procedure under GA and 71 under LA...

The vestibulo-sympathetic reflex (VSR) increases blood pressure (BP) upon arising to maintain blood flow to the brain. The optimal directions of VSR activation and whether there are changes in heart rate (HR) are still not clear. This was studied with manually-driven translations, which had pulses and oscillatory linear accelerations of 0.2-2.5 g along the naso-occipital, interaural, and dorso-ventral axes in Isoflurane-anesthetized male, Long-Evans rats. BP and HR were recorded with intra-aortic sensors and accelerationd with 3-D linear accelerometer...

Aortic dissection is very rare in obstetrics, but it is a fatal disease. A 37-weeks primigravida woman with dyspnea and pitting edema presented to our emergency room. The patient was diagnosed with preeclampsia and underwent an emergency cesarean section under spinal anesthesia. The patient complained of severe dyspnea after the cesarean section, and the chest computed tomography scan was done. With the finding of aortic dissection, cardiopulmonary arrest occurred 5 hours after the cesarean section, and the patient died without reaction to cardio-pulmonary resuscitation...

Patients with aortic diseases have a high rate of cardiac, cerebrovascular, or pulmonary comorbidities. Open surgery or endovascular interventions of the aorta are associated with high perioperative cardiac risk. Simple scoring systems for preoperative risk stratification can be used to identify high-risk patients. In these patients, further diagnostic and therapeutic interventions are required to reduce perioperative morbidity and mortality. In contrast, low-risk patients can be identified, who may proceed to intervention without additional cardiopulmonary diagnostic testing...

Early induction of therapeutic hypothermia (TH) is recommended in out-of-hospital cardiac arrest (CA); however, currently no reliable methods exist to initiate cooling. We investigated the effect of high flow transnasal dry air on brain and body temperatures in adult porcine animals. Adult porcine animals (n = 23) under general anesthesia were subject to high flow of transnasal dry air. Mouth was kept open to create a unidirectional airflow, in through the nostrils and out through the mouth. Brain, internal jugular, and aortic temperatures were recorded...

BACKGROUND: Gly16arg polymorphism of the adrenergic β2-receptor is associated with the elevated cardiac output (Q) in healthy gly16-homozygotic subjects. We questioned whether this polymorphism also affects Q and regional cerebral oxygen saturation (SCO2) during anesthesia in vascular surgical patients. METHODS: One hundred sixty-eight patients (age 71 ± 6 years) admitted for elective surgery were included. Cardiovascular variables were determined before and during anesthesia by intravascular pulse contour analysis (Nexfin) and SCO2 by cerebral oximetry (INVOS 5100C)...

BACKGROUND: Mucopolysaccharidosis (MPS) IVA is a rare lysosomal storage disorder with multiple skeletal and non-skeletal abnormalities requiring multiple surgical interventions. It is well known that patients with MPS IVA suffer from tachycardia, but cardiac and hemodynamic alterations have not been reported to date. We investigated the cardiovascular and hemodynamic alterations in patients with MPS IVA and developed a possible patho-mechanism for cardiovascular deterioration during anesthesia...

This report describes an elderly severe aortic stenosis (AS) patient, who had a history of coronary artery bypass grafting and endovascular repair for an abdominal aortic aneurysm (AAA). Type II endoleak with enlargement of AAA was diagnosed and ligation of inferior mesenteric artery (IMA) was recommended. Because aortic valve replacement (AVR) was high risk, we planned transcatheter aortic valve implantation (TAVI). Considering risks of IMA ligation under dual antiplatelet therapy, increased blood pressure after TAVI, and general anesthesia, we performed combined TAVI and IMA ligation...

Importance: Epidural analgesia (EA) is used as an adjunct procedure for postoperative pain control during elective abdominal aortic aneurysm (AAA) surgery. In addition to analgesia, modulatory effects of EA on spinal sympathetic outflow result in improved organ perfusion with reduced complications. Reductions in postoperative complications lead to shorter convalescence and possibly improved 30-day survival. However, the effect of EA on long-term survival when used as an adjunct to general anesthesia (GA) during elective AAA surgery is unknown...
