Comparison of left internal mammary artery diameter before and after left stellate ganglion block |
p. 238 |
Divya Gopal, Naveen G Singh, AM Jagadeesh, Ajay Ture, Ashwini Thimmarayappa DOI:10.4103/0971-9784.119161 PMID:24107689Aims and Objectives: Left internal mammary artery (LIMA) is the preferred arterial conduit for coronary artery bypass grafting. Various pharmacological agents are known to increase LIMA blood flow. Sympathetic blockade mediated by stellate ganglion block (SGB) has been used to provide vasodilatation in the upper extremities and in the treatment of refractory angina. We investigated effect of left stellate ganglion block (LSGB) on LIMA diameter. Materials and Methods: In 30 diagnosed patients of triple vessel coronary artery disease, LSGB was given under fluoroscopic guidance by C6 transverse process approach using 10 ml of 1% lignocaine. LIMA diameter was measured before and 20 min after the block at 2 nd , 3 rd , 4 th and at 5 th rib level. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) were recorded before and 20 min after the block. Results: The LIMA diameter increased significantly at 2 nd (2.56 ± 0.39 vs. 2.99 ± 0.40; P < 0.0001), 3 rd (2.46 ± 0.38 vs. 2.90 ± 0.40; P < 0.0001), 4 th (2.39 ± 0.38 vs. 2.84 ± 0.41; P < 0.0001) and 5 th rib level (2.35 ± 0.38 vs. 2.78 ± 0.40; P < 0.0001). No statistically significant change occurred in HR, SBP, DBP and MAP before and 20 min after LSGB. Conclusions: LSGB significantly increased the LIMA diameter. The LSGB can be considered as an alternative to topical and systemic vasodilators for reducing vasospasm of LIMA. |

Shinsaku Yata, Masayuki Hashimoto, Toshio Kaminou, Yasufumi Ohuchi, Kimihiko Sugiura, Akira Adachi, Tsuyoshi Kawai, Masayuki Endo, Shohei Takasugi, Shuichi Yamamoto, Kensuke Matsumoto, Mika Kodani, Takashi Ihaya, Makoto Takahashi, Hisao Ito, Toshihide Ogawa DOI:10.4103/0971-9784.119164 PMID:24107690Aims and Objectives: Ethanol is widely used for the embolization treatment of vascular malformations, but it can also cause serious complications such us pulmonary hypertension, cardiopulmonary collapse and death. The complications are considered secondary to pulmonary vasospasm and ethanol-induced sludge embolism, etc., We studied the hemodynamic effects of intravenous absolute ethanol injection and ethanol sludge injection in pigs. Materials and Methods: A total of 5 pigs underwent intravenous injection of ex vivo generated ethanol-induced sludge in which residual ethanol was removed (Group S) and 4 pigs underwent intravenous injection of absolute ethanol (Group E). Hemodynamic parameters related to the pulmonary and systemic circulation were compared between the groups. Results: Transient pulmonary hypertension was observed in both groups and the hemodynamic changes were similar in both groups. Conclusions: Sludge can induce transient pulmonary hypertension or cardiopulmonary collapse, without ethanol and may be the mechanism by which ethanol induces its adverse hemodynamic effects. |

Anesthesia for gastrointestinal endoscopy in patients with left ventricular assist devices: Initial experience with 68 procedures  |
p. 250 |
Basavana G Goudra, Preet Mohinder Singh DOI:10.4103/0971-9784.119167 PMID:24107691Aims and Objectives: Continuous flow left ventricular assist devices (LVAD) have emerged as a reliable treatment option for heart failure. Because of bleeding secondary to anticoagulation, these patients present frequently for gastrointestinal (GI) endoscopy. The presently available literature on perioperative management of these patients is extremely limited and is primarily based upon theoretical principles. Materials and Methods: Perioperative records of patients with LVAD undergoing (GI) endoscopy between 2008 and 2012 were reviewed. Patient, device and procedure specific information was analyzed. Results: A total of 105 LVADs were implanted, and 68 procedures were performed in 39 patients. The most common indication was GI bleed (48/68), with yearly risk of 8.57% per patient. A total of 63 procedures were performed under deep sedation, with five procedures requiring general anesthesia. Intra-procedure hypotension was managed by fluids and (or) vasopressors/inotropes (phenylephrine, ephedrine or milrinone) guided by plethysmographic waveform, non-invasive blood pressure (NIBP) and LVADs pulsatility index (for HeartMate II)/flow pulsatility (for HeartWare). No patient required invasive monitoring and both NIBP and pulse oximeter could be reliably used for monitoring (and guided management) in all patients due to the presence of native heart's pulsatile output. Conclusion: In the presence of residual heart function, with optimal device settings, non-invasive hemodynamic monitoring can be reliably used in these patients while undergoing GI endoscopy under general anesthesia or monitored anesthesia care. Transient hypotensive episodes respond well to fluids/vasopressors without the need of increasing device speed that can be detrimental. |

Management issues during HeartWare left ventricular assist device implantation and the role of transesophageal echocardiography  |
p. 259 |
Sanjay Orathi Patangi, Anthony George, Henning Pauli, Denis O'Leary, Chandrika Roysam, Tanveer Butt, Stephan Schueler, Mahesh Prabhu, Guy MacGowan DOI:10.4103/0971-9784.119173 PMID:24107692Left ventricular assist devices (LVAD) are increasingly used for mechanical circulatory support of patients with severe heart failure, primarily as a bridge to heart transplantation. Transesophageal echocardiography (TEE) plays a major role in the clinical decision making during insertion of the devices and in the post-operative management of these patients. The detection of structural and device-related mechanical abnormalities is critical for optimal functioning of assist device. In this review article, we describe the usefulness of TEE for optimal perioperative management of patients presenting for HeartWare LVAD insertion. |

Practice guidelines for perioperative transesophageal echocardiography: Recommendations of the Indian association of cardiovascular thoracic anesthesiologists  |
p. 268 |
Kanchi Muralidhar, Deepak Tempe, Murali Chakravarthy, Naman Shastry, Poonam Malhotra Kapoor, Prabhat Tewari, Shrinivas V Gadhinglajkar, Yatin Mehta DOI:10.4103/0971-9784.119175 PMID:24107693Transoesophageal 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. |

Anesthetic and hemodynamic management of a rare case of Brucella multivalvular endocarditis in cardiogenic shock undergoing emergency aortic valve replacement and mitral valve repair |
p. 286 |
Ashok Kandasamy, Senthil Kumar Ramalingam, Bhaktavatsala Deva Reddy, Harshavardhan Krupananda DOI:10.4103/0971-9784.119182 PMID:24107698We describe a very rare case of human brucella multivalvular endocarditis. Patient presented in a state of cardiogenic shock with low urine output and a history of breathlessness. Patient was diagnosed to have brucellosis 2 months back by blood cultures and agglutination tests and was receiving doxycycline and rifampicin therapy. Echocardiography showed severe aortic regurgitation, moderate mitral regurgitation, severe left ventricular dysfunction and a mobile vegetation attached to the aortic valve. Patient was scheduled for emergency surgery; while preparing for surgery hemodynamic monitoring, non-invasive ventilation and inotropic supports were started. During surgery, the aortic valve was found perforated and the aortomitral continuity was disrupted. Aortic valve replacement and mitral valve repair were performed. Hemofiltration was used during cardiopulmonary bypass. Weaning from bypass was achieved with the help of inodilators, dual chamber pacing and intra-aortic balloon pump. |

p. 293 |
Saikat Bandyopadhyay, Sunip Banerjee, Abhijit Paul, Ratan Kumar Das DOI:10.4103/0971-9784.119184 PMID:24107700A 35-year-old woman presented with 4 months history of progressively increasing intermittent dyspnea and hemoptysis. Transthoracic echocardiography revealed a loculated mass in the left atrium (LA). A provisional diagnosis of LA myxoma was made. Intraoperatively the tumor was found extending into and closely adherent to the left pulmonary vein and could not be completely cleared off from the pulmonary venous wall. The histopathological examination of the tumor revealed it to be a myxoid malignant fibrous histiocytoma. |

Use of optimized ultrasound axis along with marked introducer needle to prevent mechanical complications of internal jugular vein catheterization |
p. 296 |
Tanmoy Ghatak, Ratender Kumar Singh, Arvind Kumar Baronia DOI:10.4103/0971-9784.119185 PMID:24107701Internal jugular vein (IJV) catheterization is a routine technique in the intensive care unit. Ultrasound (US) guided central venous catheter (CVC) insertion is now the recommended standard. However, mechanical complications still occur due to non-visualization of the introducer needle tip during US guidance. This may result in arterial or posterior venous wall puncture or pneumothorax. We describe a new technique of (IJV) catheterization using US, initially the depth of the IJV from the skin is measured in short-axis and then using real time US long-axis view guidance a marked introducer needle is advanced towards the IJV to the defined depth measured earlier in the short axis and the IJV is identified, assessed and cannulated for the CVC insertion. Our technique is simple and may reduce mechanical complications of US guided CVC insertion. |
