The presence of dynamic left ventricular outflow tract obstruction (LVOTO) can complicate the postoperative course of patients undergoing surgical aortic valve replacement (AVR). The phenomenon of LVOTO is a consequence of an interplay of various pathoanatomic mechanisms. The prevailing cardiovascular milieu dictates the hemodynamic significance of the resultant LVOTO in addition to the anatomical risk factors. A thorough understanding of the predisposing factors, mechanism, and hemodynamic sequel of the obstruction is pivotal in managing these cases. A comprehensive echocardiographic examination aids in risk prediction, diagnosis, severity characterization, and follow-up of management efficacy in the setting of postoperative LVOTO. The armamentarium of management modalities includes conservative (medical) and surgical options. A stepwise approach should be formulated based on the physiological and anatomical substrates predisposing to LVOTO. The index phenomenon occurs more frequently than appreciated and should be considered when the post-AVR patients exhibit hemodynamic instability unresponsive to conventional supportive measures. The present article provides an overview of various peculiarities of this under-recognized phenomenon in the context of the perioperative management of patients undergoing AVR.
Subarachnoid block with local anaesthetic agent and opiod as an adjuvant is a well-known technique with a good record of safety. However, some rare neurological complications like aphonia, dysphagia and tingling sensation have been reported following their administration in pregnant females posted for labour analgesia or caesarean section. We report a case of transient aphonia, aphagia and facial tingling following intrathecal administration of bupivacaine along with fentanyl for lower limb wound debridement in a male patient.
Transverse myelitis, a disorder caused by inflammation of the spinal cord is characterised by symptoms and signs of neurological dysfunction. The involvement of
Background:Organ retrieval from brain dead patients is getting an increased attention as the waiting list for organ recipients far exceeds the organ donor pool. In our country, despite a large population the number of brain dead donors undergoing organ donation is very less (2% in our study).Aims:The present study was undertaken to address issues related to organ donation and share our experience for the same.Methods:A retrospective case record analysis of over 5 years from September 2007 to August 2012 was performed and the patients fulfilling brain death criterion as per Transplantation of Human Organs and Tissue (Amendment) Act were included. Patient demographics (age, sex), mode of injury, time from injury to the diagnosis of brain death, time from diagnosis of brain death to organ retrieval and complications were analysed.Statistics Analysis:Student's t test was used for parametric data and Chi square was used for categorical data.Results:Out of 205 patients who were identified as brain dead, only 10 patients became potential organ donors.Conclusion:Aggressive donor management, increasing public awareness about the concept of organ donation, good communication between clinician and the family members and a well-trained team of transplant coordinators can help in improving the number of organ donations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
