Publication Analgesic Efficacy of Fascia Iliaca Compartment Block for Positioning During Spinal Anesthesia in Patients with Femur Fractures(Kathmandu University, 2023) Jha, A; Khatiwada, S; Pokharel, K; Ghimire, A; Singh, SN; Prasad, JNABSTRACT Background Positioning patients with femur fractures for spinal anesthesia is associated with excruciating pain. Fascia iliaca compartment block has the potential to block all nerves supplying the femur and therefore may provide effective analgesia during positioning these patients for spinal anesthesia. Objective To assess the analgesic efficacy of Fascia iliaca compartment block, during positioning patients with femur fracture for spinal anesthesia. We also assessed the duration of analgesia and the requirement for rescue analgesics in the postoperative period. Method Seventy adult patients with fracture femurs were randomly divided into two equal groups (A and B). Patients in both groups received fentanyl one mcg/kg intravenously, 20 minutes before positioning them for spinal anesthesia. Patients of group B additionally, received ultrasound-guided Fascia iliaca compartment block with 40 ml of 0.25% Ropivacaine, immediately after intravenous fentanyl. Numerical rating score (0-10) was used for the assessment of pain at five, 10, and 20 minutes after the block and immediately after positioning patients for spinal anesthesia. Result Immediately after positioning patients for spinal anesthesia, the numerical rating score of pain was 5.06±1.5 in group A and 2.49±1.2 in group B (p<0.001). The duration of analgesia was 799.7±62.1 minutes in group B and 314.65±118.9 minutes in group A (p<0.001). One (2.8%) patient of group B and 18(51.4%) patients of group A required rescue analgesics within four to twelve hours in the postoperative period (p=0.001). In group A, seven patients were satisfied with the analgesia technique while in group B, 17 were satisfied and eight patients were strongly satisfied (p<0.001). Conclusion Ultrasound-guided Fascia iliaca compartment block is effective in reducing pain during positioning patients with femur fractures for spinal anesthesia. Patients receiving this block had a prolonged duration of analgesia, required lesser analgesics, and were more satisfied in the postoperative period as compared to patients not receiving the block. KEY WORDS Fascia Iliaca compartment block, Positioning, Postoperative analgesiaPublication Cheiro-Oral Syndrome(Kathmandu University, 2018) Thapa, L; Amatya, R; Maharjan, S; Gaurishankar, N; Shrestha, AM; Bhattarai, S; Singh, SN; Gongal, DN; Devkota, UPABSTRACT Cheiro-Oral Syndrome (COS) is a very rare neurological syndrome associated with varied etiology. We report a 53-year-old man presented with left sided perioral and ipsilateral hand/fingers burning sensation for a one-month duration. On examination, he had hypesthesia over left perioral and distal palmar aspect of all five fingers. MRI revealed subacute infarct in the posterior limb of right internal capsule adjacent to and minimally involving thalamus. He was diagnosed as Cheiro- Oral Syndrome as a result of ischemic stroke and managed.

Methods: Ninety patients were randomized in three groups and were received 24ml of study drugs. The groupA [Lignocaine with adrenaline (1.5%)], groupB [Lignocaine with adrenaline (1.5%)] +500μg Neostigmine, and group C (Lignocaine with adrenaline (1.5%) +4mg Dexamethasone) for brachial plexus block through supraclavicular approach. The observed parameters were onset of analgesia, completion of sensory and motor blockade, Duration of analgesia, Surgeon’s score, side effects, number of supplemental analgesics doses and Visual analogue scale (VAS) score for pain in 12 hour of post-operative period. Results: Mean onset of analgesia 4.6±1.1 , 4.4 ±0.8 , 3.8±1.8 mins in group A,B and C respectively and the Mean onset of motor blockade were 7.7± 2.0, 7.0±1.8, 6.0 ± 2.1mins in group A,B and C respectively. Similarly Mean Complete sensory block in 10.6 ±3, 10.4±2.5, and 8.9±2.2mins and Mean complete motor block in 17.3±4.3, 17.2 ±4.0 and 14.7±3.5 mins in group A, B and C respectively were achieved. Duration of analgesia was 176.5±53.5, 225.7±53.3 and 454.2±110.7 mins in group A, B and C respectively. Duration of analgesia in group C was statistically signi cant in comparison with other groups. The number of mean analgesic requirement by group C (0.9±0.4) was signi cantly (p- 0.005) lower. The mean VAS was signi cantly lower in groupC in 12 hours post-operatively. Conclusion: The onsets of action, duration of analgesia were better in dexamethasone group and also need less number of rescue analgesics requirement.Publication Postoperative Nausea and Vomiting in Patients Undergoing Total Abdominal Hysterectomy Under Subarachnoid Block: A Randomized Study of Dexamethasone Prophylaxis(Kathmandu University, 2012) Khatiwada, S; Bhattarai, B; Biswas, BK; Pokharel, K; Acharya, R; Singh, SN; Uprety, DABSTRACT Background Postoperative nausea and vomiting is a common distressing problem in patients undergoing gynaecological surgery under anaesthesia including central neuraxial blockade, which requires frequent medical interventions. Objectives We aimed to find out the antiemetic effect of prophylactic dexamethasone for prevention of postoperative nausea and vomiting in patients undergoing total abdominal hysterectomy under subarachnoid block. Influences of dexamethasone on patient satisfaction and postoperative analgesia were also observed as secondary objectives. Methods This was a prospective, randomized, double blind, placebo controlled study conducted in BPKIHS, a Tertiary care University based hospital from January 2009 to April 2009, for a period of four months. This study involved 80 American Society of Anaesthesiologist Physical Status I&II patients undergoing total abdominal hysterectomy under subarachnoid block. Patients were divided into two groups of 40 each to receive either 4 mg of dexamethasone (group D) or normal saline (group N) in volume of 2 ml intravenously 1 hourr prior to subarachnoid block. Surgery was allowed to start with block height of at least T8 dermatome. Intraoperative and postoperative nausea and vomiting was observed using nausea and vomiting scale every 4 hour for 24 hours. Results Seven (17.4%) patients in group D and 11 (27.5%) patients in group N had nausea and vomiting in the intraoperative period (P=0.284). Sixteen (40%) patients in group D experienced nausea and vomiting in the postoperative period as compared to 27 (67.5%) in group N (P =0.0136). Accordingly, the mean requirement of rescue antiemetic was less in group D compared to Group N (P=0.042). Further, only 15 (37.5%) patients in group D required postoperative supplemental analgesic as compared to 23 (57.5%) in group N (P=0.058). After 24 hrs of surgery, 26 (65%) patients expressed satisfaction in group D as compared to 16 (40.0%) in group N (P =0.025). Conclusions Use of dexamethasone prior to subarachnoid block in patients undergoing total abdominal hysterectomy significantly reduces the incidence of nausea and vomiting and the requirement of antiemetic in the postoperative period, with better patient satisfaction. KEY WORDS Dexamethasone, gynaecological surgery, postoperative nausea and vomiting, subarachnoid blockPublication Propofol Sedation During Spinal Anaesthesia - A Dose Finding Study(Kathmandu University, 2011) Ghimire, A; Bhattarai, B; Rahman, TR; Singh, SN; Koirala, S; Tripathi, MABSTRACT Background It is important to be able to measure and maintain a specific sedation level to compare outcomes of different levels of sedation during anesthesia and the aims include general patient comfort, freedom from specific discomfort, and some amnesia for both the block procedure and the surgical operation, in order to meet the patient’s preference and safety. In this prospective randomized clinical study, we compared the three different infusion doses of propofol. Objective To find out the appropriate infusion dose of propofol for optimal sedation without causing undue side effects in patients undergoing spinal anaesthesia. Method One hundred twenty patients ASA PS I-II were randomly allocated to three groups 1, 2 and 3 receiving propofol infusion at the rate of 25, 50 and 75 microgram/kg/ min with concentration of (0.5%), (1%) and (1.5%) respectively. They were observed for sedation score, hemodynamic parameters and satisfaction level. The adverse effects like respiratory depression, nausea and vomiting score were assessed. Result Median sedation score increased in a dose dependent manner, with significantly higher scores in group 2 and 3 compared with group 1. Hemodynamic parameters were better in group 1 and 2 as judged by mephentermine requirement. The awakening time after stoppage of infusion was significantly delayed in group 3 (p < 0.001). Respiratory depression, nausea and vomiting were comparable clinically. Almost three fourth of the patients were satisfied with the techniques used. Conclusion Propofol infusion at the rate of 50mcg/kg/min for sedation in spinal anaesthesia provides optimal sedation, early awakening and excellent satisfaction level in the postoperative period KEYWORDS propofol, sedation, spinal anaesthesia.Publication Study of Two Different Volumes of 0.75% Ropivacaine for Ultrasound Guided Supraclavicular Brachial Plexus Block on Successful Blockade and Diaphragmatic Motility(Kathmandu University, 2022) Prasad, JN; Adhikari, S; Singh, SN; Subedi, A; Thapa, P; Guddy, KM; Sarraf, DPABSTRACT Background Use of ultrasound guidance during supraclavicular brachial plexus block allows the usage of a lower anesthetics dose and minimizing unwanted effects of the anesthesia. Objective To compare the success of sensory blockade and the incidence of hemidiaphragmatic dysfunction in patients receiving two different volume of 0.75% Ropivacaine for ultrasound guided supraclavicular brachial plexus block. Method A prospective randomized double-blinded comparative study was conducted. Group A patients (n=30) received 20 ml and Group B (n=30) received 25 ml of 0.75% Ropivacaine for ultrasound guided supraclavicular brachial plexus block. Hemodynamic parameters, oxygen saturation, diaphragmatic excursion, onset of sensory blockade and time for completion of blockade were measured. Independent t-test, Chi-square test and Mann-Whitney U test were used to analyze the data at p value of less than 0.05 using Statistical Package for Social sciences (version 11.5). Result At 30 minutes, 29 (96.67%) patients in group B and 27 (90.0%) patients in group A had no sensation in median, radial, ulnar, musculocutaneous and medial cutaneous nerves teritories; however, it was not significant statistically (p value > 0.05). At 30 minutes in Group A, 25 (83.33%) patients had no diaphragmatic hemiparesis and five (16.67%) patients had partial diaphragmatic hemiparesis. However, three (10%) patients had no diaphragmatic hemiparesis in Group B, 25 (83.33%) patients had partial and two (6.67%) patients had complete diaphragmatic hemiparesis and it was statistically significant (p < 0.05). Age and sex had no effect on diaphragmatic hemiparesis in both groups (p value > 0.05). Conclusion The patients receiving lower volume of Ropivacaine had less incidence of hemidiaphragmatic dysfunction with similar sensory blockade as compared to the patients receiving higher volume of Ropivacaine.

Since time immemorial there have been countless efforts to improve the technique of caesarean section. One such innovative breakthrough technique is the Misgav Ladach method of caesarean of section. The objective of this trial was to compare the intraoperative and short-term postoperative outcomes between the conventional and the Misgav-Ladach technique for caesarean section. Materials and method: The randomized prospective comparative study was carried out in the department of Obstetrics and Gynaecology, B.P Koirala Institute of Health Sciences, Dharan Nepal. Four hundred patients were randomized to either Misgav Ladach or the Conventional method of caesarean section. Only term pregnancies with singleton foetuses’ were included whereas pregnancies with previous caesarean section were excluded from the study. The study period was from September 2001 to September 2004. Result: There was not much difference in the demographic variables between the two groups. The age of the patients ranged between 18-40 years. The mean age of patients in Misgav Ladach and conventional group was 24.5 and 23.6years respectively. Foetal distress was the commonest indication for caesarean section followed by non progress of labour. The mean incision to delivery interval, operating time and blood loss in the Misgav Ladach group was 1 minute 30 seconds, 16 minutes and 350ml as compared to 3 minutes, 28 minutes and 600ml in the conventional group respectively. 3.5%of patients in the Misgav Ladach group showed febrile morbidity as compared to 7% in the conventional group.19% from conventional group and only 4%from Misgav Ladach group required added analgesia. Almost equal number of patients (10-12) in each group experienced significant headache.).0.1%in the Misgav group and 5% in the Conventional group required post operative blood transfusion. Four patients from the conventional group had their wound gaped. The number of neonates requiring intensive care was sixteen (8% ) in the conventional group and 3 ( 1.5%) in the Misgav group.6.5% from conventional group and 2% from Misgav Ladach group required maternal intensive care admissions. Conclusion: Misgav-Ladach technique has been be associated with shorter operative time, quicker recovery, and lesser need for postoperative medications, when compared with traditional caesarean section (12,13) It has also been shown to be more cost-effective (12) A further advantage of the technique may be the shorter time taken for the delivery of the child.
