The most commonly used devices for direct visualization of the larynx and tracheal intubation are Macintosh and McCoy laryngoscopes. C-MAC video laryngoscope, based on the principles of indirect laryngoscopy, has been introduced into clinical practice in recent years. Video laryngoscope may be useful in difficult tracheal intubation situations. ⋯ The McCoy laryngoscope provided better attenuation of hemodynamic responses to laryngoscopy and intubation than the Macintosh and C-Mac video laryngoscope whereas more appearance of Cormack and Lehane score Class I was seen with the C-MAC video laryngoscope. Furthermore, the time taken to perform endotracheal intubation was the longest with the C-MAC video laryngoscope.

Erector spinae plane (ESP) block is a promising technique in the field of pediatric postoperative analgesia considering its safety and simplicity. ⋯ The findings suggest that US guided ESP block resulted in a more effective and longer duration of postoperative analgesia following a pediatric unilateral inguinal hernia repair compared to IIN block.

Adductor canal block is a regional anesthetic block procedure commonly employed for knee surgeries. This study aims at locating the adductor canal precisely which will be of great use for the surgeons operating on knee. ⋯ This study suggests that a point more than 3 cm below the midpoint of thigh will be the ideal location for the approach of adductor canal block.

Postspinal hypotension remains a frequent complication of subarachnoid block during cesarean section causing further maternal and fetal adverse effects. ⋯ NASG proved to be a more effective device for prevention of postspinal hypotension when compared with application of SCD or no device.

Perineural dexamethasone has been shown to improve analgesia in single injection supraclavicular block. Systemic mechanism of action of dexamethasone along with safety concerns of perineural route of administration has prompted the investigation of intravenous route as an alternative. ⋯ It is concluded from this study that intravenous and perineural dexamethasone equally prolongs the duration of analgesia in supraclavicular block. However, perineural dexamethasone resulted in a faster onset of motor and sensory blockade.
