Elderly patients undergoing cardiac surgery are at an increased risk of adverse postoperative outcomes. Frailty, a state of decreased physiological reserve, is highly prevalent among elderly patients. Despite being associated with adverse surgical outcomes, no universally accepted definition or measurement tool for frailty exists. Moreover, regardless of all the recommendations, a routine perioperative frailty assessment is often ignored. In addition to complications, frailty increases the burden to the healthcare system, which is of particular concern in Southeast Asia due to its socioeconomically disadvantaged and resource limited settings. This narrative review focuses to develop clinical practice plans for perioperative frailty assessment in the context of a cardiac surgical setting.

During current medical care, perioperative transesophageal echocardiography (TEE) has become a vital component of patient management, especially in cardiac operating rooms and in critical care medicine. Information derived from echocardiography has an important bearing on the patient′s outcome. The Indian Association of Cardiovascular and Thoracic Anaesthesiologists (IACTA) has promoted the use of TEE during routine clinical care of patients undergoing cardiac surgery. An important mission of IACTA is to oversee training and certify anesthesiologists in the perioperative and intensive care use of TEE. The provision of "Fellowship" is by way of conducting IACTA - TEE fellowship (F-TEE) examination. This has been done annually for the past 7 years using well-established curriculums by accredited national and international societies. Now, with the transformation and reconstitution of IACTA education and research cell into the newly formed Indian College of Cardiac Anaesthesia, F-TEE is bound to meet international standards. To ensure that the examinations are conducted in a transparent and foolproof manner, the guideline committee (formulated in 2010) of IACTA has taken the onus of formulating the guidelines for the same. These guidelines have been formally reviewed and updated since 2010 and are detailed here to serve as a guide to both the examinee and examiner ensuring standardization, efficiency, and competency of the IACTA F-TEE certification process.

In 1980, Transesophageal Echocardiography (TEE) first technology has introduced the standard of practice for most cardiac operating rooms to facilitate surgical decision making. Transoesophageal echocardiography as a diagnostic tool is now an integral part of intraoperative monitoring practice of cardiac anaesthesiology. Practice guidelines for perioperative transesophageal echocardiography are systematically developed recommendations that assist in the management of surgical patients, were developed by Indian Association of Cardiac Anaesthesiologists (IACTA). This update relates to the former IACTA practice guidelines published in 2013 and the ASE/EACTA guidelines of 2015. The current authors believe that the basic echocardiographer should be familiar with the technical skills for acquiring 28 cross sectional imaging planes. These 28 cross sections would provide also the format for digital acquisition and storage of a comprehensive TEE examination and adds 5 more additional views, introduced for different clinical scenarios in recent times. A comparison of 2D TEE views versus 3D TEE views is attempted for the first time in literature, in this manuscript. Since, cardiac anaesthesia variability exists in the precise anatomic orientation between the heart and the oesophagus in individual patients, an attempt has been made to provide specific criteria based on identifiable anatomic landmarks to improve the reproducibility and consistency of image acquisition for each of the standard cross sections.

Perioperative anaesthetic management of the VentrAssist TM left ventricular assist device (LVAD) is a challenge for anaesthesiologists because patients presenting for this operation have long-standing cardiac failure and often have associated hepatic and renal impairment, which may significantly alter the pharmacokinetics of administered drugs and render the patients coagulopathic. The VentrAssist is implanted by midline sternotomy. A brief period of cardiopulmonary bypass (CPB) for apical cannulation of left ventricle is needed. The centrifugal pump, which produces non-pulsatile, continuous flow, is positioned in the left sub-diaphragmatic pocket. This LVAD is preload dependent and afterload sensitive. Transoesophageal echocardiography is an essential tool to rule out contraindications and to ensure proper inflow cannula position, and following the implantation of LVAD, to ensure right ventricular (RV) function. The anaesthesiologist should be prepared to manage cardiac decompensation and acute desaturation before initiation of CPB, as well as RV failure and severe coagulopathic bleeding after CPB. Three patients had undergone implantation of VentrAssist in our hospital. This pump provides flow of 5 l/min depending on preload, afterload and pump speed. All the patients were discharged after an average of 30 days. There was no perioperative mortality.

Transoesophageal Echocardiography (TEE) is now an integral part of practice of cardiac anaesthesiology. Advances in instrumentation and the information that can be obtained from the TEE examination has proceeded at a breath-taking pace since the introduction of this technology in the early 1980s. Recognizing the importance of TEE in the management of surgical patients, the American Societies of Anesthesiologists (ASA) and the Society of Cardiac Anesthesiologists, USA (SCA) published practice guidelines for the clinical application of perioperative TEE in 1996. On a similar pattern, Indian Association of Cardiac Anaesthesiologists (IACTA) has taken the task of putting forth guidelines for transesophageal echocardiography (TEE) to standardize practice across the country. This review assesses the risks and benefits of TEE for several indications or clinical scenarios. The indications for this review were drawn from common applications or anticipated uses as well as current clinical practice guidelines published by various society practicing Cardiac Anaesthesia and cardiology . Based on the input received, it was determined that the most important parts of the TEE examination could be displayed in a set of 20 cross sectional imaging planes. These 20 cross sections would provide also the format for digital acquisition and storage of a comprehensive TEE examination. Because variability exists in the precise anatomic orientation between the heart and the esophagus in individual patients, an attempt was made to provide specific criteria based on identifiable anatomic landmarks to improve the reproducibility and consistency of image acquisition for each of the standard cross sections.

An acute coronary syndrome due to mast-cell activation in the presence of an allergen is known as Kounis Syndrome (KS). This relatively new entity of KS is being increasingly recognized among allergists, cardiologists, and emergency physicians; however, it is not well-known among anesthesiologists. We report here, a case of type 2 KS due to antibiotic administration causing sudden perioperative cardiac arrest. [ABSTRACT FROM AUTHOR]

There has been considerable controversy regarding the use of pulmonary artery catheter (PAC) in clinical practice. Some studies have indicated poor outcome in patients who were monitored with PAC. However, these studies, which have condemned the use of PAC, were conducted on patients in intensive care units, where the clinical scenarios with regard to patients′ status are somewhat different as compared to those of a cardiac operating room. This study was designed to identify the indications of PAC use in cardiac operating rooms. A questionnaire was mailed to anasthesiologists in cardiac centers and the response was analyzed.The practicing cardiac anesthesiologists recommended the use of PAC for following indications in cardiac surgery: coronary artery bypass grafting (CABG) with poor left ventricular (LV) function, LV aneurysmectomy, recent myocardial infarction (MI), pulmonary hypertension, diastolic dysfunction, acute ventricular septal rupture and insertion of left ventricular assist device (LVAD).The analysis of responses from practicing anesthesiologists clearly indicates that use of a PAC cannot be recommended as a matter of routine, but a definite role is suggested in selected groups of patients undergoing cardiac surgery.

Protective lung ventilation is the mainstay ventilation strategy for patients on extracorporeal membrane oxygenation (ECMO), as prolonged mechanical ventilation increases morbidity and mortality; the technicalities of ventilation with ECMO have evolved in the last decade. ECMO on the other end of the spectrum is a complete or total extracorporeal support, which supplies complete physiological blood gas exchanges, normally performed by the native lungs and thus is capable of delivering oxygen (O2) and removing CO equal to the metabolic needs of the patient, it requires higher flows, is more complex, and uses bigger cannulas, higher dose of heparin and higher blood volume for priming. This review describes in detail carbon dioxide removal on ECMO. [ABSTRACT FROM AUTHOR]
