The anaesthesiologist's presence during interventional radiology (IR) is increasing due to increasingly ill patients and intricate procedures. The management of a parturient in IR suite is complex in terms of logistics of an unfamiliar procedure in an unfamiliar area. ⋯ As members of a multidisciplinary team, anaesthesiologists should utilise their expertise in fluid management, transfusion therapy and critical care to prevent and treat catastrophic events that may accompany severe peri-partum bleeding. Ensuring familiarity with the variety of IR procedures and the peri-procedure requirements can help the anaesthesiologist provide optimum care in the IR suite.

Obese individuals are predisposed to difficult airway and intubation. They usually yield confusing or misleading auscultatory findings. We aimed to assess the rapidity and efficacy of ultrasonographic (USG) sliding lung sign for confirming endotracheal intubation in normal as well as overweight and obese surgical patients. ⋯ Ultrasound directed confirmation of endotracheal tube placement in overweight and obese patients is superior in speed and accuracy in comparison to the standard auscultatory method.

The true incidence of penetration of the posterior wall (through-and-through puncture) of the internal jugular vein (IJV) during cannulation is unknown. This may have implications if there is hematoma formation, penetration and/or inadvertent cannulation of an underlying carotid artery. This study compared the incidence of posterior wall puncture during IJV cannulation using ultrasound guidance versus traditional landmarks-guided technique. ⋯ Real-time ultrasound-guided IJV cannulation significantly reduces but does not wholly eliminate the incidence of posterior venous wall penetrations. It also significantly reduces the incidence of inadvertent arterial punctures and number of attempts for successful cannulation.

Premedication is an integral component of paediatric anaesthesia which, when optimal, allows comfortable separation of the child from the parent for induction and conduct of anaesthesia. Midazolam has been accepted as a safe and effective oral premedicant. Dexmedetomidine is a selective alpha-2 agonist with sedative and analgesic effects, which is effective through the transmucosal route. We compared the efficacy and safety of standard premedication with oral midazolam versus intranasal dexmedetomidine as premedication in children undergoing elective lower abdominal surgery. ⋯ Intranasal dexmedetomidine at a dose of 1 μg/kg produced superior sedation scores at separation and induction but normal behavioural scores in comparison to oral midazolam in paediatric patients.

Sevoflurane is the most often used inhalational agent in paediatric anaesthesia, but emergence agitation (EA) remains a major concern. Oral midazolam and parenteral dexmedetomidine are known to be effective in controlling EA. We attempted to elucidate whether oral dexmedetomidine is better than midazolam in controlling EA. ⋯ Premedication with oral dexmedetomidine provides smooth induction and recovery, reduces the EA and provides better analgesia and sedation as compared to oral midazolam.
