Effectiveness of addition of neostigmine or dexamethasone to local anaesthetic in providing perioperative analgesia for brachial plexus block: A prospective, randomized, double blinded, controlled study
(Kathmandu University, 2008) RK, Yadav; BP, Sah; P, Kumar; SN, Singh
Abstract Background: Various local anaesthetic agents are used for brachial plexus block.We compared effectiveness of addition of Dexamethasone versus Neostigmine to Lignocaine, adrenaline admixtures for Brachial plexus block in providing perioperative analgesia. 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.

Treatment of supracondylar fracture of the humerus (type IIB and III) in children: A prospective randomized controlled trial comparing two methods
(Kathmandu University, 2008) S, Pandey; D, Shrestha; M, Gorg; GK, Singh; MP, Singh
Abstract Background: Consensus on method of treatment of displaced supracondylar fracture of the humerus in children is still lacking. Purpose of this prospective randomized controlled study is to compare closed reduction and long arm slab application with closed reduction and percutaneous crossed Kirschner wires xation. Materials and methods: Children of age less than 12 years presented in B.P. Koirala institute of health sciences, Dharan in one year were randomly allocated to group A and group B consisting 30 patients in each group. Closed reduction and long arm posterior slab was applied in group A and in group B, closed reduction was followed by crossed Kirschner wires xation. Clinical and radiological evaluation of reduction was performed immediately after procedure and at the end of rst week, third week, third month and sixth month. Results: The groups were matched for pre fracture characteristics and post reduction evaluation. The mean follow up period in group A was 6.9 months and in group B was 7.1 months. Closed reduction failed in two patients at the rst attempt and one patient failed to retain reduction at rst week in group A. 11 patients (5 in group A and 6 in group B) were lost to follow up. Range of movement, valgus, varus and carrying angle of elbow in two groups were not signi cantly different. The mean difference of carrying angle of affected elbow as compare to normal elbow was signi cant in group A (p 0.05). Flynn’s overall rating showed 32% excellent, 36% good, 18% fair and14 % poor result in patents treated with long arm slab as compared to 58% excellent, 29% good, 13 % fair and no poor results in patients with crossed Kirschner wires xation. Conclusion: The outcome of displaced extension type supracondylar fracture of the humerus in children, managed with closed reduction and slab application are comparable with closed reduction and crossed Kirschner wire xation in terms of range of motion but is inferior in restoration of carrying angle. Good to excellent cosmetic and functional results are higher with crossed percutaneous Kirschner wires xation than with slab immobilization. Key words: closed reduction; percutaneous xation; supracondylar fracture

Antiemetic prophylaxis against postoperative nausea and vomiting with ondansetron-dexamethasone combination compared to ondansetron or dexamethasone alone for patients undergoing laparoscopic cholecystectomy
(Kathmandu University, 2008) B, Gautam; BR, Shrestha; P, Lama; S, Rai
Abstract Background: Postoperative nausea and vomiting (PONV) is a common distressing experience in patients following laparoscopic surgeries. This study was aimed at comparing the ef cacies of Ondansetron-Dexamethasone combination with each drug alone as a prophylaxis against PONV in patients after elective laparoscopic cholecystectomy done under general anaesthesia. Materials and methods: Hundred and fty ASA I and II patients, aged 23 to 65 yrs, were enrolled in this prospective, randomized, double-blind trial to receive one of three treatment regimens: 4 mg Ondansetron (Group O), 8 mg Dexamethasone (Group D) or 4 mg Ondansetron plus 8 mg Dexamethasone (Group OD) (n=50 for each). A standardized balanced general anaesthetic technique was employed. Any episode of PONV and need for rescue antiemetic were assessed at six, 12 and 24 hrs post operation. Complete response was de ned as no PONV in 24 hrs and need for rescue antiemetic was considered as failure of prophylaxis. Pain scores, time to rst analgesia demand, amount of Meperidine consumption, adverse event(s) and duration of hospital stay were recorded. Results: Complete response occurred in 66.7, 66.0 and 89.4% in Groups O, D and OD respectively. Rescue antiemetics were required in 29.2, 31.9 and 8.5% of patients in Groups O, D, and OD respectively. Signi cantly high incidence of vomiting and failure of prophylaxis (19.1%) occurred in group D during the rst six hrs (P=0.023 versus O & 0.008 versus OD). More frequent antiemetic rescue was required in group O at 6 to 24 hr interval as compared to group OD (P=0.032). Conclusion: Combination of Ondansetron and Dexamethasone is better than each drug alone in preventing PONV after laparoscopic cholecystectomy. Dexamethasone alone is signi cantly less effective in preventing early vomiting compared to its combination with Ondansetron; whereas Ondansetron alone is less effective against late PONV as compared with combination therapy. Key words: Antiemetic prophylaxis; Dexamethasone; laparoscopic cholecystectomy; Ondansetron; postoperative nausea and vomiting (PONV)
