Publication A Comparative Study on Epidemiology, Spectrum and Outcome Analysis of Physical Trauma cases Presenting to Emergency Department of Dhulikhel Hospital, Kathmandu University Hospital and its Outreach Centers in Rural Area(Kathmandu University, 2013) Shrestha, R; Shrestha, SK; Kayastha, SR; Parajuli, N; Dhoju, D; Shrestha, DABSTRACT Background Physical trauma is one of the major cause of mortality and morbidity among young and active age group and its increasing trend is of main concern. There are only few studies concerning the spectrum of physical trauma in Nepal. Objective This study aims to evaluate the epidemiological spectrum, the extent, severity of the physical trauma and the outcome evaluation of patients with physical trauma over a period of one year in the emergency department of the Kathmandu University Hospital and compare the same parameters with those patients presenting to the various outreach centers of the hospital in the community. Methods Patient treatment files from the emergency department and the reports from various outreach centers were retrieved for a period of one year (May 2011 to April 2012). Epidemiological information, mode, type and anatomic location of injuries were recorded. Outcome evaluation was assessed by number of patients discharged from emergency department of the hospital or the outreach centers after the treatment, patients admitted for inpatient management and referred to other centers for further specialty management. Result In a period of one year, total 2205 (20%) of physical trauma cases presented to the emergency department and 1994 (6.12%) in the outreach centres. Most commonly involved age group in physical trauma both in Hospital set up and in Community set up were the young adults (15 to 49 years). Fall from height was the commonest mode of injury followed by road traffic accidents among the patients coming to the hospital while significant number of trauma patients coming to outreach centers were due to fall from height. In the hospital set up, 1525 (69.2%) of the cases were discharged while 537 (24.4%) needed inpatient management and 85 (3.8%) needed referral to other centers for the specialty management. In case of outreaches, half of the patients were discharged after the primary treatment and almost another half were referred to the hospital, mainly for need of further investigations. Conclusion Fall related injuries and road traffic accidents are the most common mode of trauma in the hospital set up and fall related injuries are the single most important mode of trauma seen in the outreaches. Mostly young adults in their active period of life are involved in physical trauma so appropriate preventive measures through public health approach should be included in comprehensive trauma management for reducing mortality and morbidity rates related to physical trauma.

Addition of intrathecal ketamine and opioids to local anaesthetics seems to improve the quality of block and prolong the duration of analgesia. Objectives The purpose of this study was to compare the effect of intrathecal ketamine mixed with hyperbaric bupivacaine to intrathecal fentanyl mixed with hyperbaric bupivacaine. Methods One hundred parturients ASA Grade I scheduled for elective or semiurgent caesarean section under spinal anaesthesia were randomly divided into two groups. Group A received 2ml (10 mg) hyperbaric bupivacaine 0.5% plus 25 mg preservative free ketamine. Group B received 2ml (10mg) hyperbaric bupivacaine 0.5% plus 25μg fentanyl. The patients were observed intraoperatively for the onset of sensory block, degree of motor block and total duration of analgesia. Results The time to achieve Bromage scale 3 motor blockade was shorter in Group A than in Group B.(p= 0.445) whereas time to achieve highest dermatomal level of sensory block was shorter in Group A than in Group B (p= 0.143). The duration of spinal analgesia was longer in Group B than in Group A (p= 0.730). The frequency of side effect such as sedation score was higher in Group A compared to Group B (p= 0.048). The incidence of pruritus was significantly higher in Group B compared to Group A (p = 0.000). Conclusion Addition of preservative free ketamine lead to faster onset of sensory and motor blockade, although it did not prolong the duration of spinal analgesia compared to addition of fentanyl in parturients undergoing caesarean section with spinal anaesthesia.

Sniffing position for laryngoscopy is considered as gold standard and ideal position. Several studies have questioned the validation of sniffing potion. Objectives This study aims to compare relative efficacy of sniffing position and simple head extension for visualization of glottis during direct laryngoscopy. Methods Four hundred patients undergoing elective surgery under general anesthesia requiring endotracheal intubation were randomized into two groups and study was concluded. Glottic visualization was assessed using modified Cormack and Lehane classification. After laryngoscopy, tracheal intubation was performed and intubation difficulty scale was noted. Results Both the groups were comparable regarding glottis visualization. Both the groups were comparable in demographic profiles. All the intubation difficulty scale variables were comparable in both the groups except N3. Total Intubation Difficulty Score was better in sniffing position than in simple head extension group. Conclusion Glottic visualization and intubation difficulty score was better in sniffing position as compared to simple head extension. KEY WORDS sniffing position, simple head extension, direct laryngoscopyPublication Comparison of Ultrasound Guided Transversus Abdominis Plane Block Versus Local Wound Infiltration for Post Operative Analgesia in Patients Undergoing Gynaecological Surgery Under General Anaesthesia(Kathmandu University, 2014) Ranjit, S; Shrestha, SKABSTRACT Background Transversus abdominis plane block has been recently developed as a part of multimodal post operative analgesic techniques. We compared the analgesic efficacy of this technique with local bupivacaine infiltration in patients undergoing gynaecological surgeries with pfannenstiel incision and lower midline incision under general anaesthesia. Objectives To evaluate the efficacy of ultrasound guided transversus abdominis plane block for postoperative analgesia. Methods Patients were randomly allocated to three groups: control group (n=15), transversus abdominis plane block group (n=15), who received bilateral transversus abdominis plane blockwith 0.25% bupivacaine, and local infiltration group (n=15), who received local wound infiltration with 0.25% bupivacaine at the end of surgery. All patients received intramuscular diclofenac 12 hourly and intravenous tramadol SOS in the postoperative period. Visual analogue scores for pain were assessed at 1,2,4,8,12 and 24 hours postoperatively and these were compared between the three groups. Average tramadol consumption in 24 hours were also compared among the three groups. Data were subjected to univariate ANOVA test and chi- square test. Level of significance was set at 0.05. Results Visual analogue scores were significantly less in transversus abdominis plane block group and effect lasted up to 12 hours at rest postoperatively and 8 hours during cough and movement. Conclusion Bilateral Transversus abdominis plane block was effective in reducing postoperative pain scores for 8 to 12 hours postoperatively. This block was also successful in reducing postoperative opioid requirement.

Although several methods of treatment have been described, but all have been associated with high recurrence rates. This study was carried out to evaluate the advantages and results of rhomboid excision and Limberg flap reconstruction in the management of pilonidal sinus disease. Objective: To evaluate the advantages and results of rhomboid excision and Limberg flap reconstruction in the management of pilonidal sinus disease Material and Methods: This was prospective descriptive study conducted in Unit III, Department of Surgery, Kathmandu Medical College Teaching Hospital from August 2013 to August 2015. First 50 patients with diagnosis of pilonidal sinus were included .Exclusion criteria was patients with pilonidal abscess. Results: Total 50 patient were included in 2 years time. Mean age was 23.48 ± 3.9 years with all male patients only. Median duration of surgery was 32 ± 4.4 minutes .Median time for normal activities was 21± 3.9 days and median follow up time was 18±8.5 months. No recurrence was noted till then. Post surgery, patient applied hair removal cream: 44%, hair shaving: 34% and laser therapy for hair follicles: 22%. Conclusion: Modified Limberg flap is better option for pilonidal sinus with least recurrence. However, post surgical counseling for hair removal is very important in order to prevent recurrence and should be multidisciplinary approach along with dermatologist colleagues. Keywords: pilonidal sinus, modified limberg flap, hair removalPublication Preemptive use of Small Dose Fentanyl Suppresses Fentanyl Induced Cough(Kathmandu University, 2012) Shrestha, SK; Bhattarai, B; Shah, RSABSTRACT Background Fentanyl, a synthetic opioid, is a popular choice amongst anaesthesiologists in the operating room. Pre induction intravenous fentanyl bolus is associated with coughing in 28 – 65% of patients. Fentanyl induced cough is not always benign and can be remarkably troublesome at the most critical moment of anaesthesia when airway reflex is lost. Objectives To study the effect of pre emptive use of minimal dose fentanyl through the peripheral venous cannulae on the incidence of cough by a larger bolus of intravenous fentanyl. Methods One hundred and fifty patients aged 18 -75 years undergoing elective surgical procedures were randomized into three groups of 50 each. The first group received 0.5 ml saline 0.9 % intravenously one minute prior to the administration of fentanyl 150μg (3 ml); the second group received pre emptive fentanyl 25μg(0.5ml) prior to the administration of fentanyl 125μg(2.5ml); and the third group received preemptive fentanyl 25 μg(0.5ml), followed by the administration of fentanyl 150μg(3ml).. Based on the number of coughs observed, cough severity was graded as mild(1-2), moderate (3-5),or severe (>5). Results The incidence of fentanyl induced cough was significantly lower in both pre emptive group 4(8%) for 125μg fentanyl and 7(14%) for 150μg than in the saline group 15(30%). Conclusion Pre- emptive use of minimal dose fentanyl 25μg administered one minute before a larger bolus dose of fentanyl (125 or 150μg ) can effectively suppress cough.

This report describes the prevalence of subclinical atherosclerotic vascular disease in a Nepalese population over the age of forty years as measured by ABI and CCA IMT and their association with established cardiovascular risk factors. Materials and methods: Ultrasonic evaluation of ABI and CCA IMT was done in 195 individuals of age 40 years and above who had presented to an outpatient department. Patients with established diagnosis of coronary artery disease or symptomatic for peripheral arterial disease were excluded from the study. Results: The prevalence of atherosclerotic disease as measured by ABI was 18.5% and there was a statistically significant correlation between ABI and CCA IMT and other established cardiovascular risk factors such as smoking, diabetes mellitus and hypertension. Conclusions: We recommend that ABI as measured by sphygmomanometer be incorporated into routine cardiovascular screening and when found to be abnormal further confirmed by Doppler assessment of ABI and CCA IMT as surrogate markers of atherosclerotic vascular disease. Key words: atherosclerosis, cardiovascular disease, peripheral vascular disease, carotid arteriesPublication Six Minute Walk Distance and Reference Equations in Normal Healthy Subjects of Nepal(Kathmandu University, 2015) Shrestha, SK; Srivastava, BABSTRACT Background The self-paced six minute walk test is a simple assessment for sub-maximal functional capacity. It correlates well with sophisticated tests and gives good prediction for morbidity, mortality, quality of life and pulmonary functions. Objective To evaluate six minute walk distance in healthy adults to identify reference values and formulate reference equations. Method We conducted six minute walk test on 250 random volunteers at and above 18 years of age as per standard protocol. Age, gender, height and weight were measured. Pre- test and post-test vital parameters were recorded including pulse oximetry. The six minute walking distance was identified in all subjects. Multiple regression analysis was done to formulate regression equations to predict six minute walking distance. This also correlated age, gender, height, weight, body mass index with six minute walking distance. Result The mean six minute walking distance was 489±86 meters with males walking 509±82 meters and females 445±78 meters. Age, gender, weight and body mass index had significant contribution for prediction of six minute walking distance. Gender was the single most important predictor. Height had the least significance. Depending on coefficients of these variables we formulated three regression equations and tested them for accurate prediction. The two best equations were identified as: Predicted SMWD = 395–1.5xAge+2.47xWT–35.89xGender and Predicted SMWD = 440–1.82xAge–53.07xGender+5.12xBMI. Conclusion Gender, age and height are the most important predictors of six minute walking distance. Reference values and equations for both genders, different age groups with varying weights were derived for local population. KEY WORDS Predicted equation, reference values, six minute walk test.Publication Total thyroidectomy: the treatment of choice in differentiated thyroid carcinoma(Kathmandu University, 2005) Shrestha, SK; Joshi, MR; Sharma, SKIntroduction: Clinically detectable thyroid carcinoma constitutes less than 1% of human cancers. Ninety percent of all thyroid malignancies are differentiated papillary and follicular carcinoma. Surgery plays a key role in differentiated thyroid carcinoma as it carries excellent prognosis, lower recurrence rate and low mortality rate but controversy persists for extent of surgery and optimal surgical management of lymph node metastasis. Patient and Method: A retrospective analysis was done for the cases that underwent total thyroidectomy with lymph node dissection for differentiated carcinoma of thyroid in Kathmandu Medical College during two year periods (Oct 2001 to Oct 2003). Result: In our experience with 18 cases of Differentiated Thyroid Carcinoma (DTC) treated with total thyroidectomies and lymph node dissection, papillary carcinoma was predominant with 83% incidence. Disease was prevalent in 50 to 60year age group. Except two cases of transient hypocalcaemia and few wound related complications, there have been no other complications. Conclusion: Total thyroidectomy with lymph node dissection is safe and effective, so, the treatment of choice in cases of differentiated thyroid carcinoma.Publication Use of percutaneous thread loop to hold the vermiform appendix during laparoscopic appendectomy(Kathmandu University, 2007) Joshi, MR; Shrestha, SK; Thapa, PB; Koirala, U; Bhattarai, P; Dongol, UMS; Singh, DR; Sharma, SKIntroduction: Laparoscopic appendectomy, although not as widely performed as laparoscopic cholecystectomy, it has got definite advantage over the conventional open procedure. Controversy exists regarding the closure of stump. Our institute practices intracorporeal knot tying using 3 ports. Difficulties are observed in three port technique to hold the appendix during knot tying. We use a percutaneous thread loop. Advantage of the use of loop was evaluated. Patients and method: Prospective study was carried out during 18 months. Total cases were randomly divided in non-loop and with loop group. Operative procedure was same. Cases were compared in terms of operating time, post-operative hospital stay and complications. Results: Total patients were 66. Thirty two in non-loop group and 34 in with loop group. Mean age was 27.89 yrs. Most of the cases were females (62%). Mean operating time was less in loop group although statistically not significant. There was no difference in post operative hospital stay. Use of loop was not associated with added complications. Conclusion: Use of percutaneous loop to hold the appendix reduces the operating time and replaces the need of fourth port. It is safe and effective without any increased morbidity.
