Most of them are asymptomatic. About 30-40% presents with tracheo-oesophageal symptoms like dyspnea and dysphagia. A 27 year-old female presented with persistent dysphagia for 6 months duration and cause of persistent dysphagia was the right sided aortic arch with aberrant left subcalvian artery from Kommerell’s diverticulum. The diagnosis was made through combination of chest X-Ray, echocardiography, non-ionic contrast swallow and Computed Tomography angiography. Non-invasive modalities (CT and MR Angiography) play an important role in diagnosis and pre-operative surgical planning providing relationship with the surrounding structures especially trachea and esophagus.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Anesthetic Management of Apert Syndrome: A Case Report 2021-06-07T09:35:24+00:00 Megha Koirala Gentle S Shrestha Pankaj Joshi Bashu D Parajuli <p>Apert syndrome is a rare autosomal dominant disease associated with abnormalities of skull, face and limbs. These patients present for different types of surgeries. To the anesthesiologists,they pose special challenge during airway management, manifesting as difficulty in bag-mask ventilation and increased incidence of airway obstruction. Here, we report a case of a child with Apert syndrome undergoing syndactyly release under general anesthesia, in whom severe bronchospasm and a failed bag-mask ventilation occurred during the emergence of anesthesia requiring re-insertion of laryngeal mask airway.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Single Stage Surgery for Open Lisfranc Injury: A Case Report 2021-06-07T09:35:26+00:00 Rajesh B Lakhey Prawesh S Bhandari Govinda KC <p>Management of open Lisfranc injuries is challenging. The improper management of the injuries might lead to bad results like skin necrosis and arthritis of Lisfranc’s joints. A case of Myerson type A Gustilo Grade IIIB open Lisfranc injury was managed with single stage debridement and internal fixation.

It is a state of chronic inflammation of airways. The aim of this study was to measure the plasma fibrinogen level in patient with COPD and find the relationship between plasma fibrinogen levels and severity of airflow obstruction.</p> <p><strong>Methods</strong><br>This observational study was conducted from September 2017 to October 2018, where 80 eligible patients with the diagnosis of acute exacerbation of COPD (AECOPD) were included in the study and their plasma fibrinogen level was measured at the time of discharge. Clinical information was obtained and pulmonary function test (PFT) was done.</p> <p><strong>Result</strong><br>A total of 80 patients were enrolled. The mean age of the patient was 67.87±11.60 years. Plasma fibrinogen level was 159±12.72 mg/dl in mild COPD, 273.52±62.34 mg/dl in moderate COPD, 312.30±103.67 mg/dl in severe COPD, and 487±102.76 mg/dl in very severe COPD. The comparison between groups showed significant difference in plasma fibrinogen level (p&lt;0.001). There was significant negative correlation between plasma fibrinogen level and forced expiratory volume in one second (FEV1%) predicted (r=-0.71, p=0.01).</p> <p><strong>Conclusion</strong><br>High plasma fibrinogen level on discharge was found in COPD patients with severe airflow obstruction, frequent exacerbations and severe level of dyspnoea during AECOPD. </p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Nebulized Magnesium Sulphate Versus Saline as an Adjuvant in Acute Exacerbation of Chronic Obstructive Pulmonary Disease in a Tertiary Centre of Nepal: A Randomized Control Study 2021-06-07T09:35:11+00:00 Manjita Bajracharya Ramesh P Acharya Ram P Neupane Rekha Sthapit Apurva R Tamrakar <p><strong>Introduction</strong> <br>Magnesium has been shown to have bronchodilator properties in asthma and chronic obstructive pulmonary disease (COPD). Therapeutic benefits of nebulized magnesium in asthma has been seen. The purpose of this study was to compare therapeutic benefits of nebulised magnesium sulphate as an adjuvant with normal saline in patients with COPD exacerbation.</p> <p><strong>Methods</strong><br>It was a randomized single blind interventional study of 172 cases of acute exacerbation of COPD presenting (AECOPD) with a peak expiratory flow rate (PEFR) &lt;300 L/min measured 20 min after initial management. Patients received 5 mg salbutamol mixed with 3 ml isotonic magnesium sulphate or 3 ml normal saline on three occasions at 30 min intervals via nebulizer. The primary outcome measured was PEFR at 90 min and hospital admission, noninvasive or invasive ventilation and mortality were taken as secondary outcomes.</p> <p><strong>Results</strong><br>The mean PEFR were 86.3±11.9 l/min, 97.6±19.1 l/min and 99.6±15.2 l/min after nebulization with magnesium sulphate and 79.17±14.11 l/min, 90.17±18.27 l/min and 93.17±20.63 l/min at 30, 60 and 90 minutes respectively in normal saline group which were statistically significant differences. Total 91.9% were admitted in ward and 8.1% got admitted in Medical and intermediate intensive care units from magnesium group and 81.7% were admitted in ward and 18.3% required ICU admissions in saline group. Differences in ventilation and mortality were insignificant.</p> <p><strong>Conclusion</strong><br>Nebulized magnesium sulphate as an adjuvant to salbutamol treatment in the setting of AECOPD has therapeutic benefit on PEFR but no effect in terms of hospital admission, requirement of invasive or non-invasive ventilation and mortality.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Risk Score for Prediction of Severe Postoperative Complications After Pancreaticoduodenectomy 2021-06-07T09:35:13+00:00 Surendra Shah Ramesh S Bhandari Pradeep Vaidya Yogendra P Singh Paleswan Joshi Lakhey <p><strong>Introduction</strong> <br>Morbidity after pancreaticoduodenectomy (PD) still remains high. Postoperative pancreatic fistula (POPF) is the most common cause of increased morbidity after PD. Assessment of predictability of risk score for severe postoperative complications was the objective of this study.</p> <p><strong>Methods</strong><br>This was a retrospective observational study. Patients undergoing pancreaticoduodenectomy at Tribhuvan University Teaching Hospital (TUTH) between January 2017 to December 2017 were included in the study. Variables were recorded from case sheets of the patients. The “Risk Score” was calculated using the pancreatic duct diameter and body mass index (BMI). Association of risk score and severe postoperative complications were analyzed.</p> <p><strong>Results</strong><br>A total number of patients were 43, including 23 (53.5%) males and 20 (46.5%) females. The mean age was 57.09 ± 11.85 years ranges from 29 years to 76 years. The POPF and delayed gastric emptying (DGE) was 23.3% (10/43); and post-pancreaticoduodenectomy hemorrhage (PPH) was 11.6% (5/43). Severe postoperative complications were present in 13.9% (6/43) patients. In univariate analysis, pancreatic duct diameter (p=0.045) and Risk Score (p=0.02) were significantly associated with severe postoperative complications after PD. However none of them were significant in multivariate analysis.</p> <p><strong>Conclusion</strong><br>Risk score failed to predict severe postoperative complication after pancreaticoduodenectomy.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Diurnal Variability of Peak Expiratory Flow Rate in Healthy Adult Employees of a Medical College of Kathmandu 2021-06-07T09:35:14+00:00 Gita Khakurel Kalyan Gautam Sanat Chalise <p><strong>Introduction</strong> <br>Peak expiratory flow measurement is a simple measure of respiratory capacity to diagnose airflow obstruction and monitor treatment response in patients with pulmonary diseases. But there is wide diurnal variability in its values. The objectives of this study was to determine the diurnal variability of peak expiratory flow rate in healthy adults.</p> <p><strong>Methods</strong><br>This cross-sectional study was done in employees of Kathmandu Medical College, Duwakot between March to August 2020. A total of 74 subjects of 30-45 years were included in the study. After adequate training, subjects were asked to record their own peak expiratory flow five times a day by Mini-Wright peak flow meter. Diurnal variability was expressed as amplitude percent mean and standard deviation percent mean. Data analysis was done by student’s unpaired t-test and one-way ANOVA.</p> <p><strong>Results</strong><br>The mean peak expiratory flow rate (in L/min) were lowest in morning (male: 478.75±45.91; female: 362.86±20.51) followed by progressive rise throughout the day and highest at evening (male: 531.88 ±43.95; female: 415.71±20.97) with slight fall at bedtime (male: 486.88±46.38; female: 362.86±20.51). The difference in peak expiratory flow rate at different time periods was statistically significant in both males and females (p&lt;0.001). The diurnal variability as calculated by amplitude percent mean and standard deviation percent mean were found to be significantly higher in females (p=0.001 and 0.004 respectively).</p> <p><strong>Conclusion</strong><br>There is a variation of peak expiratory flow rate recorded during different time points of the day in healthy adults.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal A Tale of β-Lactamases and Multidrug Resistance in Pseudomonas aeruginosa Isolated from Inpatients in a University Hospital 2021-06-07T09:35:16+00:00 Santosh K Yadav Sangita Sharma Shyam K Mishra Jeevan B Sherchand <p><strong>Introduction</strong> <br>In this era of modern medicine, antimicrobial resistance can be regarded as a major health calamity. The emergence of multidrug-resistant (MDR) Pseudomonas aeruginosa strains poses therapeutic challenges and lead to treatment failure in hospitalized patients. This study was conducted to determine various types of β-lactamases among MDR&nbsp;P. aeruginosa isolates recovered from hospitalized patients.</p> <p><strong>Methods</strong><br>This study was conducted at Tribhuvan University Teaching Hospital, Maharajgunj, Nepal. The clinical samples collected from inpatients were processed for detection of P. aeruginosa isolates and antibiotic susceptibility profile was determined. The MDR strains were identified and ceftazidime-resistant isolates were subjected for detection of extended-spectrum-β-lactamase (ESBL), metallo-β-lactamase (MBL), and&nbsp;Klebsiella pneumoniae carbapenemase (KPC).</p> <p><strong>Results</strong><br>A total of 161 P. aeruginosa isolates were recovered during the study period encompassing 73.3% (n=118) MDR isolates. The MDR isolates included 50.0% (n=59) from lower respiratory tract infections; and 39.8% (n=47) were from the intensive care unit patients. The MDR isolates showed a high resistance profile towards piperacillin, cephalosporins, and fluoroquinolones (&gt;85%). Resistance to carbapenems and aminoglycosides were up to 80% and 60% respectively. Extended spectrum-β-lactamase, MBL, and KPC mediated resistance were seen in 34.7%, 43.6%, and 14.4% MDR isolates, respectively.</p> <p><strong>Conclusion</strong><br>Multidrug resistance as well as resistance mediated by β-lactamases production were high among P. aeruginosa isolates.&nbsp; Therefore, early detection of antimicrobial resistance and rational use of antibiotics play a critical role to fight against this MDR pathogen.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Correlation of Status of Mastoid with Outcomes of Myringoplasty with Cortical Mastoidectomy in Mucosal Otitis Media with High Risk Perforation 2021-06-07T09:35:17+00:00 Asmita Shrestha Hari Bhattarai Pabina Rayamajhi Rabindra B Pradhananga <p><strong>Introduction</strong> <br>Chronic mucosal otitis media is one of the common disease prevalent in our society. This study was done to correlate the status of mastoid with outcomes of myringoplasty with cortical mastoidectomy in mucosal otitis media with high risk perforation.</p> <p><strong>Methods</strong><br>This prospective, observational study was done at Department of Otorhinolaryngology and Head and Neck Surgery, Tribhuvan University Teaching Hospital. Thirty-four patients of ag|e 15 and above with chronic mucosal otitis media having high-risk perforation undergoing cortical mastoidectomy with myringoplasty were included. The status of middle ear, aditus, and mastoid air cells were assessed. Post-operatively, patients were assessed for graft uptake and hearing after three months. The post-operative graft uptake and hearing results were correlated with the peroperative status. Four patients who had preoperative sensorineural hearing loss were studied in terms of graft uptake only.</p> <p><strong>Results</strong><br>The graft success rate in patients with normal mastoid air cells was 90% whereas in diseased cases was 71.4% which was statistically not significant with p value 0.20. The success rate in terms of hearing was 68.8% in normal mastoid whereas it was 64.3% in diseased mastoid which was statistically not significant with p-value of 1.</p> <p><strong>Conclusion</strong><br>In correlation with the status of mastoid air cells with graft uptake and hearing result, the observed differences were not statistically significant. However, averages of post-operative air conduction threshold and air-bone gap of all cases were better as compared to preoperative levels.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Outcome of Carotid Endarterectomy in a Tertiary Center of Nepal: A Retrospective Study 2021-06-07T09:35:19+00:00 Prashiddha B Kadel Uttam K Shrestha Kajan R Shrestha Dinesh Gurung <p><strong>Introduction</strong> <br>Carotid endarterectomy for carotid artery disease is one of the surgeries performed by vascular surgeons for carotid artery disease. The objective of this study is to describe the early and late outcome of the patient undergoing carotid endarterectomy and the association between the complication and comorbidities present previously in the patient.</p> <p><strong>Methods</strong><br>All patients undergoing carotid endarterectomy at Manmohan Cardiothoracic Vascular and Transplant Centre between April 2010 to April 2020 were included. The follow-up data for upto a year from medical and clinical records, telephone interview regarding the immediate and late postoperative complications in patients with and without comorbidities were investigated and compared.</p> <p><strong>Results</strong><br>The total study population was 42 patients. Two patients (4.7%) developed stroke, one immediately in postoperative period and the other during follow up. There were two deaths (4.7%) postoperatively due to cardiac events and three (7.14%) recurrences of carotid stenosis among whom one (2.5%) developed late stroke. Twenty six patients (61.90%) were symptomatic prior to the procedure of which 20 patients (47.61%) had brain infarct. Overall one year survival was 95.2% post procedure and overall complication rate was 7.14%. The consequence in the form of death and stroke occurred more in the patients with comorbidities (3vs1) p=0.42.</p> <p><strong>Conclusion</strong><br>The immediate and late postoperative complications following carotid endarterectomy were death (4.7%), stroke (4.7%), cranial nerve injury (9.5%). The most frequent cause of death was postoperative cardiac event. Though major complications occurred more frequently in patients having comorbidities, it was statistically insignificant.</p> 2021-04-30T00:00:00+00:00 Copyright (c) 2021 JIOM Nepal Knowledge of Nurses Working in Critical Care Areas Regarding Ventilator Associated Pneumonia Prevention Bundles in a Tertiary Level Cardiac Centre 2021-06-07T09:35:20+00:00 Sandip Bhandari Medha Sharma Gentle S Shrestha <p><strong>Introduction</strong> <br>Prevention of ventilator associated pneumonia (VAP) is influenced by the knowledge and practices of nurses. This study was conducted to assess the knowledge of nurses working in critical care areas of a tertiary level cardiac centre regarding VAP prevention bundles.</p> <p><strong>Methods</strong><br>In this descriptive study, 57 nurses working in critical care areas were included, they completed a self-administered questionaire containing demographic information followed by 18 multiple response questions. With the respondents choosing one or more correct answers, the percentage of correct answer for each options was obtained.
