RESUMO
BACKGROUND: Sevoflurane is an inhalational agent of choice in paediatric anaesthesia. For management of airways in children a suitable alternative to ETT is a paediatric proseal laryngeal mask airway (benchmark second generation SAD). Various studies have shown that less sevoflurane concentration is required for LMA insertion in comparison to TI. BIS is a useful monitor of depth of anaesthesia. AIMS: To compare concentration of sevoflurane (end tidal and MAC value) required for proseal laryngeal mask airway insertion and tracheal intubation in correlation with BIS index. METHOD: The prospective randomised single blind study was done in children between 2 and 9 years of ASA I and II and they were randomly allocated to Group P (proseal laryngeal mask airway insertion) and Group TI (tracheal intubation). No sedative premedication was given. Induction was done with 8% sevoflurane and then predetermined concentration was maintained for 10 min. Airway was secured either by proseal laryngeal mask airway or endotracheal tube without using muscle relaxant. End tidal sevoflurane concentration, MAC, BIS, and other vital parameters were monitored every minute till insertion of an airway device. Insertion conditions were observed. Statistical analysis was done by ANOVA and Students t test. RESULTS: Difference between ETLMI (2.49 ± 0.44) and ETTI (2.81 ± 0.65) as well as MACLMI (1.67 ± 0.13) and MACTI (1.77 ± 0.43) was statistically very significant, while BISLMI (49.05 ± 10.76) and BISTI (41.25 ± 3.25) was significant. Insertion conditions were comparable in both the groups. CONCLUSION: We can conclude that in children airway can be secured safely with proseal laryngeal mask airway using less sevoflurane concentration in comparison to tracheal intubation and this was supported by BIS index.
JUSTIFICATIVA: Sevoflurano é um agente inalatório de escolha em anestesia pediátrica. Para o manejo de vias aéreas em crianças, uma opção adequada para o TET é uma MLP pediátrica (referência de segunda geração SAD). Vários estudos mostraram que uma menor concentração do sevoflurano é necessária para a inserção da ML em comparação com a IT. O BIS é um monitor útil da profundidade da anestesia. OBJETIVOS: Comparar a concentração de sevoflurano (valores no fim da expiração e da CAM) necessária para a inserção de MLP e intubação traqueal em correlação com o BIS. MÉTODO: Estudo prospectivo, randômico e cego conduzido com crianças entre 2-9 anos, estado físico ASA I-II, randomicamente alocados nos grupos P (inserção de MLP) e IT (intubação traqueal). Pré-medicação sedativa não foi administrada. A indução foi feita com sevoflurano a 8% e, em seguida, a concentração predeterminada foi mantida durante 10 minutos. A via aérea foi garantida por MLP ou tubo endotraqueal, sem o uso de relaxante muscular. A concentração de sevoflurano no fim da expiração, CAM, BIS e outros parâmetros vitais foram monitorados a cada minuto até a inserção do dispositivo respiratório. As condições de inserção foram observadas. A análise estatística foi feita com o teste t de Student e Anova. RESULTADOS: As diferenças entre TEIML (2,49 ± 0,44) e TEIT (2,81 ± 0,65), bem como CAMIML (1,67 ± 0,13) e CAMIT (1,77 ± 0,43), foram estatisticamente muito significativas; enquanto BISIML (49,05 ± 10,76) e BISIT (41,25 ± 3,25) foram significativos. As condições de inserção foram comparáveis em ambos os grupos. CONCLUSÃO: Podermos concluir que a MLP em comparação com a intubação traqueal pode ser segura para a via aérea de crianças com o uso de menos concentração de sevoflurano, o que foi confirmado pelo BIS.

RESUMO
BACKGROUND AND OBJECTIVES: A review of all the adjuncts for intravenous regional anaesthesia concluded that there is good evidence to recommend NonSteroidal Anti-Inflammatory agents and pethidine in the dose of 30mg dose as adjuncts to intravenous regional anaesthesia. But there are no studies to compare pethidine of 30mg dose to any of the NonSteroidal Anti-Inflammatory agents. METHODS: In a prospective, randomized, double blind study, 45 patients were given intravenous regional anaesthesia with either lignocaine alone or lignocaine with pethidine 30mg or lignocaine with ketprofen 100mg. Fentanyl was used as rescue analgesic during surgery. For the first 6h of postoperative period analgesia was provided by fentanyl injection and between 6 and 24h analgesia was provided by diclofenac tablets. Visual analogue scores for pain and consumption of fentanyl and diclofenac were compared. RESULTS: The block was inadequate for one case each in lignocaine group and pethidine group, so general anaesthesia was provided. Time for the first dose of fentanyl required for postoperative analgesia was significantly more in pethidine and ketoprofen groups compared to lignocaine group (156.7±148.8 and 153.0±106.0 vs. 52.1±52.4min respectively). Total fentanyl consumption in first 6 h of postoperative period was less in pethidine and ketoprofen groups compared to lignocaine group (37.5±29.0 mcg, 38.3±20.8mcg vs. 64.2±27.2mcg respectively). Consumption of diclofenac tablets was 2.4±0.7, 2.5±0.5 and 2.0±0.7 in the control, pethidine and ketoprofen group respectively, which was statistically not significant. Side effects were not significantly different between the groups. CONCLUSION: Both pethidine and ketoprofen are equally effective in providing postoperative analgesia up to 6h, without significant difference in the side effects and none of the adjuncts provide significant analgesia after 6h.

Fentanil foi usado como analgésico de resgate durante a cirurgia. Durante as seis primeiras horas de pós-operatório, analgesia foi fornecida via injeção de fentanil e, entre seis e 24 horas, analgesia foi fornecida via comprimidos de diclofenaco. Os escores visuais analógicos para dor e do consumo de fentanil e diclofenaco foram comparados.

JUSTIFICACIÓN Y OBJETIVOS: una revisión sobre todos los adyuvantes para la anestesia regional intravenosa concluyó que hay buenas evidencias para recomendar los agentes antiinflamatorios no esteroideos y la petidina en dosis de 30 mg como adyuvantes para la anestesia regional intravenosa. Sin embargo, no hay estudios comparando la petidina (30 mg) con cualesquiera de los agentes antiinflamatorios no-esteroideos. MÉTODOS: en un estudio prospectivo, aleatorizado y doble ciego, 45 pacientes recibieron anestesia regional intravenosa con solamente lidocaína o lidocaína con petidina (30 mg) o lidocaína con ketoprofeno (100 mg). El fentanilo fue usado como analgésico de rescate durante la cirugía. Durante las 6 primeras horas del postoperatorio, la analgesia fue suministrada vía inyección de fentanilo y entre 6 y 24 h, la analgesia fue suministrada vía comprimidos de diclofenaco.

BACKGROUND AND OBJECTIVE: Intravenous regional anesthesia (IVRA) for upper limb surgeries with traditional high dose of lidocaine can lead to life threatening side effects. In order to avoid these potential life threatening side effects, many modified techniques of IVRA have been attempted by using a low dose of lidocaine, muscle relaxant and opioid. METHOD: The present study is carried out in sixty unpremedicated ASA Class 1 and 2 patients to compare the sensory and motor characteristics, cardio-respiratory parameters and side-effects during intra-operative and post-tourniquet deflation period between the patients who received 40mL of 0.5% lidocaine alone (n=30) and those who received a combination of 40mL of 0.25% lidocaine with 0.05mg fentanyl and 0.5mg vecuronium (n=30) in IVRA for upper limb orthopedic surgeries. The results were analyzed for statistical significance using a paired student t test. RESULTS: The difference between the two groups regarding the mean time of onset and complete sensory and motor block was statistically significant. But 15 minutes after the injection of anesthetic solution, there was complete sensory and motor block in both groups. CONCLUSION: Although the short delay observed in the onset and attainment of complete sensory and motor block may theoretically delay the start of surgery for 10-15 minutes but clinically that time will be spent in the preparation of surgical field. So this combination can be used safely and effectively in intravenous regional anesthesia for upper limb orthopedic surgeries with reduced chance of local anesthetic toxicity.
