Publication 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. KEY WORDS Postoperative analgesia, transversus abdominis plane block, ultrasound guidance, visual analogue score.Publication Effect of preloading on haemodynamic of the patient undergoing surgery under spinal anaesthesia(Kathmandu University, 2010) Singh, J; Ranjit, S; Shrestha, S; Sharma, R; Marahatta, SBAbstract Background: Hypotension and bradycardia after conduction of spinal anaesthesia are common side effects because of sympathetic blockade. Efforts to prevent these complications have been attempted like preloading with crystalloids, colloids or use of vasopressors. The role of volume preloading to prevent haemodynamic changes associated with spinal anaesthesia has been recently questioned. Objective: The objective of the study was to investigate the effects of volume preload on changes of patient’s hemodynamic. Materials and methods: A Quasi- experimental design was used to conduct the study. Taking written informed consent, 40 patients of age group 18-45 years and ASA grade I and II undergoing surgery under spinal anaesthesia in operation theatre of Dhulikhel Hospital were selected as the sample of the study and allocated randomly to 2 groups. Group I did not receive volume preload and Group II received preload of 1000 ml of Ringer’s lactate solution within 30 minutes immediately before giving the spinal anaesthesia. An observational checklist was used to collect demographic, intra- operative and post-operative records of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR). Results: The findings revealed that the haemodynamic changes occurred in all patients. The decrease in SBP, MBP and DBP from baseline was statistically significant at all points of time (p=0.000). The decrease in HR from baseline was not statistically significant at all points of time (p>0.05). The overall incidence of hypotension was 50%, among which 9 (45%) were from without preload group and 11 (55%) were from with preload group. The incidence of hypotension was similar in groups, sexes and surgical conditions (General Surgery, Gynae/Obs and Orthopaedics). There were no signifi cant differences in haemodynamic changes among groups. Conclusion: On the basis of findings, it is concluded that volume preloading had no effect on the incidence of hypotension and bradycardia after spinal anaesthesia.

Difficulties in identification of the risk factors, in diagnosing and in prevention, have intensified the problem. Objectives To measure the incidence of ventilator associated pneumonia in intensive care unit and to identify the risk factors associated. Methods A prospective observational cohort study of 69 patients who were mechanically ventilated for more than 48 hours were evaluated to find out the development of nosocomial pneumonia and presence or absence of risk factors. Data were subjected to univariate analysis using chi-square and t-test. Level of significance was set at 0.05. Results Twenty two (31.88%) out of 69 patients developed ventilator associated pneumonia, majority of them between four days to 14 days. Reintubation, invasive lines, H2 blockers and low PaO2/FiO2 were identified as major risk factors in our study. Enteral feeding via nasogastric tube and use of steroids was not associated with development of ventilator associated pneumonia. The patients with ventilator associated pneumonia had significantly longer duration of mechanical ventilation (18.88±7.7 days vs 7.36±4.19 days) and stay (29±17.8 days vs 9.22±5.14 days). The morality was similar for both the groups with or without ventilator associated pneumonia. Conclusion The incidence of ventilator pneumonia is high. Patients requiring prolonged ventilation, re-intubation, more invasive lines and H2 blockers, are at high risk and need special attention towards prevention. KEY WORDS nosocomial infection, prolonged mechanical ventilation, risk factors, ventilator associated pneumoniaPublication Predicting difficulties during laparoscopic cholecystectomy by preoperative ultrasound(Kathmandu University, 2007) Sharma, SK; Thapa, PB; Pandey, A; Kayastha, B; Poudyal, S; Uprety, KR; Ranjit, SBackground: The aim of this study was to determine whether the preoperative USG finding can predict the risk of conversion or difficulty during the laparoscopic cholecystectomy. Materials and methods: 200 patients undergoing Laparoscopic cholecystectomy at Kathmandu Medical College Teaching Hospital were included. Sonographic parameters like size of gall bladder, wall thickness, distance between hepaticoduodenal ligament and Hartmann’s pouch and the size of stone were taken into consideration and difficulties in terms of adhesions around gall bladder, anatomy of calot’s triangle and difficulty in peeling off gall bladder from the bed and retrieval were analyzed. Result: In 8 of 200 patients (4%), LC was converted to open procedure. In univariate analysis all the sonographic parameters we had included in this study were statically significant (p value <0.05). Conclusion: Preoperative sonographic signs can predict the difficulty in laparoscopic cholecystectomy
