Central venous cannulation (CVC) through right internal jugular vein (IJV) route is routinely performed in paediatric patients undergoing major surgery and in those admitted to intensive care units. A novel technique (modified short-axis out-of-plane [MSA-OOP]) to improve first pass success rate of ultrasound-guided IJV CVC in neonates and infants is being compared with conventional SA-OOP method. ⋯ The use of MSA-OOP ultrasound technique for IJV CVC cannulation results in a higher first-attempt success rate and reduces the number of cannulation attempts.

Tracheal tube introducers (TTIs) are a useful aid to a conventional laryngoscopy-intubation method of upper airway access in adults. However, even when TTIs are used, successful tracheal intubation is not guaranteed. Apart from suboptimal practice proficiency and unavailability of the complete repertoire of TTI, the physical attributes of the TTI have a role to play. Our report on the management of two cases highlights the importance of selecting a TTI with appropriate angled tip characteristics to facilitate successful guided intubation.

Any technique that employs a fresh gas flow that is less than the alveolar ventilation can be classified as low-flow anaesthesia. The complexities involved in the calculation of uptake of anaesthetic agents during the closed-circuit anaesthesia made this technique less popular. ⋯ Moreover, the time has arrived for each of us, the practicing anaesthesiologists, to move towards the practice of low-flow anaesthesia, to achieve lesser theatre and environmental pollution and also to make anaesthesia more economical. The article also reviews low-flow anaesthesia (LFA) in paediatrics, recent advances such as automated LFA and updates on currently undergoing research to retrieve and reuse anaesthetic agents.

Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) during apnoea has shown to delay desaturation. The primary objective was to compare time to desaturate to <90% during apnoea with THRIVE versus traditional preoxygenation followed by apnoeic oxygenation. ⋯ During apnoeic periods time to desaturate to <90% was significantly prolonged with use of THRIVE.
