Introduction: The present study compared video laryngoscope with Macintosh laryngoscope in terms of laryngoscopic time, total intubation time, Cormack and lehane scale and stress response while intubating. Materials and methods: After a standardized technique of induction of anesthesia, Group MCL (53 cases) intubated with Macintosh laryngoscope and Group VVL (53cases) intubated with Vividtrac Video laryngoscope. We compared laryngoscopic time, total intubation time, Cormack and lehane scale and stress response while intubating in these two groups. Results: The heart rate and blood pressure was above immediately after post intubation and started declining to reach post induction value at about three to five minutes in both groups (p values > 0.05).The mean tracheal intubation time was 11.05 seconds in MCL group and 18.05 seconds in VVL group (p-0.001). All cases in VVL group were intubated in first attempt, but one patient in MCL group required two attempts for success (p->0.05). Visualisation of glottis and non-alignment of the airway axis was better with VVL (p-0.001). There is no desaturation noted in all of the 106 cases. Conclusion:Vivid trac Laryngoscope has a comparable similar safety profile with Macintosh laryngoscope with respect to deleterious haemodynamic response produced by rigid manipulation of airway. Vivid trac Video Laryngoscope, a rigid channeled indirect laryngoscope provides always the better view of the laryngeal inlet than the Macintosh direct laryngoscope. Intubation time in Vividtrac video laryngoscopy was more than conventional laryngoscopy.
Background: Brachial plexus block is an excellent method for attaining optimal operating conditions for upper limb surgeries by producing complete muscular relaxation, maintaining haemodynamic stability and the associated sympathetic block. The present study was conducted to assess supraclavicular brachial plexus block with or without dexamethasone as an adjuvant to 0.5% levobupivacaine. Materials and methods: 50 patients of 18-60 years were allocated in two groups of 25 each. In group I, patients received 30 ml of 0.5% isobaric levobupivacaine with 2 ml of isotonic sodium chloride. In group II patients received 8mg (2ml) dexamethasone in addition to 30ml of 0.5% isobaric levobupivacaine. Results: Group I had 15 males and 10 females and group II had 12 males and 13 females. The mean duration of surgery was 62.4 minutes in group I and 63.2 minutes in group II, onset of sensory blockade was 10.4 minutes in group I and 8.1 minutes in group II, onset of motor blockade was 15.4 minutes and 13.2 minutes, duration of sensory blockade was 658.2 minutes and 925.6 minutes, duration of motor blockade was 572.4 minutes and 764.2 minutes and total analgesic requirement was 22 and 1 in in group I and in group II respectively. The difference was significant (P< 0.05). Conclusion: Dexamethasone found to reduce the time to onset of sensory and motor blockage and prolongs the duration of analgesia.
