Several video laryngoscopes had demonstrated their superiority over conventional oral and nasal intubation techniques. King Vision video laryngoscope has fewer studies supporting its suitability for oral intubations. However, its suitability as a nasal intubating device has not been yet evaluated. We evaluated the suitability of King Vision video laryngoscope for nasotracheal intubation comparing with TruviewPCD. ⋯ King Vision video laryngoscope is just as effective as TruviewPCD video laryngoscope for successful nasotracheal intubation.

Both intubation and extubation are associated with pressor response. ⋯ Ropivacaine when used through nebulization preinduction effectively reduced both intubation and extubation responses when compared to saline. However, there was no significant difference between the ropivacaine and lignocaine on extubation response.

Positioning fracture femur cases for sub arachnoid block (SAB) is challenging. Fascia iliaca compartment block (FICB) is low skilled, helps positioning, and provides analgesia. Dexmedetomidine as an adjuvant prolongs analgesia. ⋯ FICB ensures patient comfort during positioning for SAB and provides postoperative analgesia. Dexmedetomidine significantly prolongs postoperative analgesia.

In the past, many wash-in schemes have been used with initially high fresh gas flow (FGF) to achieve the necessary alveolar concentration of inhalational agent in 10-15 min. This study was designed to show whether 1-1-12 wash-in scheme proposes an earlier achievement of induction or is there any requirement of high FGF phase to know the time taken for induction with and without nitrous oxide (N2O). ⋯ Time taken to attain FAD from 1% to 6% was 4 min in both the groups. It is concluded that the recitation of 1-1-12 wash-in scheme is autonomous on the use of N2O and high FGF phase.

The use of intravenous sedation during cardiac surgery to reduce awareness has been practised routinely during past few years and the two most commonly used drugs include propofol and dexmedetomidine, but their effects on hemodynamics and postoperative outcomes in cardiac surgery is continually being evaluated. ⋯ HR and MAP were significantly less in dexmedetomidine group compared to propofol group (P < 0.05). Both the groups had a similar requirement of vasopressors and inotropes. The duration of postoperative ventilation and length of stay in the ICU were significantly shorter in the dexmedetomidine group (P < 0.05). The risk of delirium was significantly less in dexmedetomidine group (P < 0.05). From our study we concluded, that the perioperative infusion of dexmedetomidine produces better hemodynamic stability, reduces the risk of postoperative delirium, and leads to shorter ICU stay.
