Objective: α-2-agonists cause sympathetic inhibition combined with parasympathetic activation and have other properties that could be beneficial during cardiac anesthesia. We evaluated the effects of dexmedetomidine as an anesthetic adjuvant compared to a control group during cardiac surgery. Methods: We performed a retrospective analysis of prospectively collected data from all adult patients (> 18 years old) undergoing cardiac surgery. Patients were divided into two groups, regarding the use of dexmedetomidine as an adjuvant intraoperatively (DEX group) and a control group who did not receive α-2-agonist (CON group)...

BACKGROUND: Post-thoracotomy pain syndrome (PTPS) is pain that recurs or persists along a thoracotomy incision for at least two months following surgery. Dexmedetomidine (dex) is an α-2 agonist that also has analgesic, sedative-hypnotic, and sympatholytic properties. OBJECTIVES: To determine the effect of pre-emptive dexmedetomidine on the incidence of PTPS in patients undergoing coronary artery bypass grafting (CABG). PATIENTS AND METHODS: This randomized clinical trial enrolled 104 candidates for elective coronary artery bypass grafting (CABG) and randomly assigned them to either a dex group or a control group...

A 2-month-old male with dysmorphic facies, neonatal thrombocytopenia, left congenital cataract, and long bone abnormalities became hypotensive with ST depression on induction of anesthesia for congenital cataract repair. Echocardiogram demonstrated decreased left ventricular function (ejection fraction 46%), mild mitral valve regurgitation (MR), and regional wall motion abnormalities. The left coronary artery could not be visualized. Subsequent cardiac catheterization confirmed atresia of the left main coronary artery...

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...

PURPOSE: Volatile anesthetics possess cardioprotective properties, but it is unknown if the cardioprotective effects extend equally to all members of the class. Although sevoflurane is a relatively newer anesthetic than isoflurane, its introduction into practice was not preceded by a head-to-head comparison with isoflurane in a trial focusing on clinically important outcomes. Our objective was to determine whether sevoflurane was non-inferior to isoflurane on a clinically important primary outcome in a heterogeneous group of adults undergoing cardiac surgery...

BACKGROUND: Patients on antiplatelet therapy following percutaneous coronary intervention can become coagulopathic due to infection. Performing regional anesthesia for bilateral surgery in such cases is challenging. We report a case of successful combined inguinal femoral and subgluteal sciatic nerve blocks (CFSNBs) for simultaneous bilateral below-knee amputations in a coagulopathic patient on antiplatelet therapy. METHODS: A 70-year-old male patient presented with pain in both feet due to diabetic foot syndrome...

BACKGROUND: General anesthesia may induce inadvertent hypothermia and this may be related to perioperative cardiovascular complications. Microvascular reactivity, measured by the recovery slope during a vascular occlusion test, is decreased during surgery and is also related to postoperative clinical outcomes. We hypothesized that microvascular changes during surgery may be related to intraoperative hypothermia. To evaluate this, we conducted a randomized study in patients undergoing off-pump coronary artery bypass surgery, in which the effect of prewarming on microvascular reactivity was evaluated...

OBJECTIVE: Several studies have suggested that the cardioprotective effects of halogenated anesthetics in cardiac surgery result in reduced cardiac biomarker release compared with total intravenous anesthesia (TIVA). These findings came from relatively small randomized clinical trials and meta-analyses. The authors of this study hypothesized that the beneficial effects of volatile anesthetics translate into a reduced length of hospital stay after coronary artery bypass grafting surgery (CABG) with cardiopulmonary bypass...

BACKGROUND: Minimal invasive surgeries are carried out to benefit the patient with less pain, blood loss, mechanical ventilation and hospital stay; a smaller scar is not the aim. Minimal invasive cardiac surgeries are carried out via small sternotomy, small thoracotomy and via robotic arms. Subxiphoid route is a novel method and avoids sternotomy. AIM: This case series is an attempt to understand the anesthetic modifications required. Secondly, whether it is feasible to carry out subxiphoid coronary artery bypass surgery...

The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function...

In patients undergoing off-pump coronary artery bypass surgery (OPCAB), it is important to attenuate myocardium injury during the surgery. The present study aimed to observe the cardioprotection induced by sevoflurane induction and maintenance compared with propofol intravenous anesthesia, and to detect its potential protection against acute myocardial injury with sensitive biomarkers. In total, 36 patients undergoing OPCAB were randomly assigned into two groups, receiving sevoflurane (n=18) or propofol (n=18) as the induction and maintenance anesthetic agent...

Conventionally general anesthesia has been the preferred anesthetic technique for coronary artery bypass grafting (CABG). Ever since the first awake CABG the concept though appearing promising is still being continually evaluated. From the Indian perspective, the practice has been largely limited to certain institutions and seems to be not widely practiced across India. This case reports our experience with this technique from the western part of the country.

We report the successful anesthetic management of video-assisted left upper lobectomy in a patient with ischemic heart disease using an intra-aortic balloon pump (IABP). An 81-year-old man with severe ischemic heart disease was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. Although he had severe ischemic heart disease, coronary intervention such as percutaneous cardiac intervention or coronary artery bypass grafting was impossible due to severe coronary stenosis. IABP was instituted through the femoral artery before inducing anesthesia...

Currently, the immediate extubation in the operating room is necessary for the patients undergoing off-pump coronary artery bypass (OPCAB). To achieve UFTA, anesthesiologists should control general anesthesia. We report the case series of UFTA for the patients undergone OPCAB at our hospital. Forty patients receiving OPCAB between April 2012 and April 2014 were retrospectively analyzed. We divided the patients into those extubated in the operating room (Extubation group) and those not (Intubation group). The extubation criteria included adequate revascularization, adequate hemostasis, ratio between Pa(O2) and FI(O2) more than 250, body temperature above 36 degrees C, stable hemodynamics without noradrenaline, without IABP, and normal postoperative chest X-ray...
