Publication A case of left atrial myxoma: Anaesthetic management(Kathmandu University, 2006) Pradhan, B; Acharya, SPLeft Atrial Myxomas are notorious for their varied presentations. We describe one such case which initially presented with hemiparesis and seizures and was diagnosed as cerebral infarction and treated accordingly and decompression craniotomy with hinge flap was done for raised ICP and impending brain herniation. The main cause was a left atrial myxoma, which was diagnosed only in follow up. The myxoma has embolised to give rise to cerebral infarction. The LA myxoma was then successfully operated under general anaesthesia and Cardiopulmonary bypass (CPB). Key words: Hemiparesis, Cerebral infarction, Left Atrial (LA) MyxomaPublication Application of “the Sequential Organ Failure Assessment (SOFA) score” in predicting outcome in ICU patients with SIRS(Kathmandu University, 2007) Acharya, SP; Pradhan, B; Marhatta, MNAbst ract Background: Various scoring systems have been developed to prioritize patient admission and management in ICU. The objective of this prospective, observational cohort study was to evaluate application of one such system, the Sequential Organ Failure Assessment (SOFA) Score in predicting outcome in ICU patients with SIRS. Patients and Methods: Fifty patients admitted to a six bed multidisciplinary ICU with SIRS were consecutively enrolled in the study and SOFA scores were calculated at zero hour, after 48 hrs, and after 96 hrs and patients followed till discharge from hospital. Results: When compared to outcome, the non survivors had high initial, mean and highest SOFA scores as compared to survivors. (p value = 0.002, <0.001, <0.001 respectively). Delta SOFA was not significantly associated with outcome. (p value= 0.117). The initial SOFA score > 11 predicted a mortality of 90%. (OR 23.72, 95%CI2.68- 209.78, p=0.004). Similarly, mean SOFA score of > 7 predicted a mortality of 73.9% (OR 22.7, 95%CI 5.0 – 103.5, p<0.001) and high SOFA score > 11 predicted a mortality of 87.5% (OR 32.66, 95%CI 5.82-183.179, p< 0.001). Area under receiver operating characteristic (ROC) curve for mean SOFA was 0.825, for high SOFA was 0.817 and for initial SOFA was 0.708. Thus mean, high and initial SOFA scores were helpful in predicting between the survivors and the non survivors. Conclusion: The SOFA scoring system is useful in predicting outcomes in ICU and thus help in proper utilization of ICU resources. Key words: Sequential Organ Failure Assessment (SOFA) Score, Systemic Inflammatory Response Syndrome (SIRS), Intensive Care Unit (ICU).Publication Unexplained apnoea and loss of consciousness during sub arachnoid block for caesarean section(Kathmandu University, 2009) Acharya, SP; Marhatta, MN; Amatya, RAbstract Sub arachnoid block (SAB) is often perceived safe by many anesthesiologists and other faculties but is also not completely safe choice especially in pregnant females, as the incidence of complications and local anaesthetic agent toxicity is high in these groups of patients. Here we present four such cases out of the seventeen patients over a period of six months, who developed apnea and transient loss of consciousness after spinal anesthesia for lower segment caesarean section. Typically all these patients after spinal anesthesia developed difficulty in breathing, became apnoea and had loss of consciousness for about a minute or two. The apnea was relieved with bag and mask ventilation following which the patient regained consciousness and start breathing normally. The rest of the procedure was uneventful. We presented these cases with aim of sharing similar experiences, and to aware about the possibility of such events as these events do occur frequently but case reports and literatures are unavailable. Key words: Apnoea, loss of consciousness, lower segment caesarean section (LSCS), Sub arachnoid block (SAB).
