Literature suggests that glottic view is better when using McGrath(®) Video laryngoscope and Truview(®) in comparison with McIntosh blade. The purpose of this study was to evaluate the effectiveness of McGrath Video laryngoscope in comparison with Truview laryngoscope for tracheal intubation in patients with simulated cervical spine injury using manual in-line stabilisation. ⋯ Both laryngoscopes are reliable in case of simulated cervical spine injury using manual-in-line stabilisation with 100% success rate and good glottic view.

Diabetic patients are prone for the limited joint mobility syndrome. The atlanto-occipital joint involvement limits adequate extension of head and neck during laryngoscopy making intubation difficult. The collagen glycosylation starts in the fourth and fifth inter-phalangeal joints. The degree of inter-phalangeal involvement can be assessed by scoring the ink impression made by the palm of the dominant hand (palm print [PP] sign) The aim of our study was to evaluate the PP sign as a screening tool for predicting difficult laryngoscopy in diabetic patients. ⋯ The PP test appears to be the most sensitive and specific in the prediction of difficult laryngoscopy in diabetic patients.

Priming principle refers to administration of a small dose of non-depolarising blocker, which when followed by a large intubating dose produces a relatively rapid and profound blockade to ensure suitable conditions for endotracheal intubation. We aimed to compare the effects of rocuronium, vecuronium, and atracurium as "pretreatment" drugs on intubating conditions with rocuronium facilitated endotracheal intubation. ⋯ Pretreatment with rocuronium bromide can facilitate endotracheal intubation in 60 s irrespective of non-depolarising muscle relaxants used for priming; however, it cannot attenuate haemodynamic changes associated with laryngoscopy and intubation.

Aging population is a major demographic trend worldwide. Globally, 50% of all the elderly individuals are estimated to undergo atleast one surgical procedure and post-operative cognitive dysfunction (POCD) is one of the most common and often poorly understood post-operative complications in this section of the population. This randomised prospective study was conducted to assess the post-operative cognitive status in the elderly undergoing non-cardiac surgery, evaluate the cognitive parameters affected, evaluate the potential risk factors and thereby analyse the potential for implementation of preventive strategies. ⋯ POCD is a definite complication after surgery and anaesthesia in the elderly population. Gender emerged as a significant risk factor with increasing age as a dominating factor contributing to POCD.

Central venous catheter (CVC) insertion induces pain and discomfort to a conscious patient despite application of a local anaesthetic (LA) field block and this pain can be greatly lessened by using additional analgesics. The aim of this study was to evaluate the efficacy of dexmedetomidine along with LA field infiltration in controlling pain and discomfort associated with CVC insertion. ⋯ Pre-procedural bolus dexmedetomidine infusion provides adequate analgesia and patient comfort for CVC insertion along LA field block. However, the tendency for excessive sedation and bradycardia associated with dexmedetomidine render it less desirable for this purpose.
