Shivering-the "Big Little Problem" has an incidence of 60% in early recovery phase following general anaesthesia. A number of techniques have been tried to prevent postoperative shivering. Previous study showed that, ondansetron in higher doses reduces postoperative shivering. ⋯ Groups P and G differ significantly than in Group S (p<0.05). However, the difference between Groups P and G was not statistically significant (p>0.05). The prophylactic use of granisetron (40mcg.kg(-1)) and pethidine(25mg) intravenous were found to be effective in preventing postoperative shivering.

Anaesthesia for conjoined twins, either for separation surgery, or for MRI or other evaluation procedures is an enormous challenge to the paediatric anaesthesiologist. This is an extra challenging surgery because we the anaesthesiologists need to care for two patients at the same time instead of just one. Anaesthesia for conjoined twins 'separation surgery mainly centered on the following concerns: 1. ⋯ Long marathon surgery with massive fluid shifts and loss of blood & blood components and their rapid replenishment. 3. Meticulous planning for organized management of long hours of anaesthetic administration in two paediatric subjects simultaneously with multi surgical specialties' involvement and their unique requirements. We report the anaesthetic and intensive care management of one pair of Pygopagus separation surgery and also the review of literature and world statistics.

Cardiovascular collapse following use of methylmethacrylate for lower limb surgeries has been reported. However there are no reports of cement reaction following shoulder arthroplasty. We report series of four patients exhibiting cement reaction. ⋯ Severe hemodynamic derangement and transient hypoxemia was observed during cemented arthroplasty of shoulder and knee respectively. Peripheral vasodilatory effects of the cement monomer, fat and marrow embolism and activation of the clotting cascade in the lungs, all contribute to cement reaction. Early and aggressive resuscitation with use of vasopressors, establishment of invasive hemodynamic monitoring and surgical modifications are the key to prevention of catastrophic outcome.

Laryngeal mask airway (LMA) is increasingly being used in children as it is less invasive compared to endotracheal intubation and causes less discomfort in the postoperative period. However, some concerns remained about its safety during positive pressure ventilation in children. In a prospective randomized trial, 100 ASA I and II children weighing between 10-20 kg in the range of 2-10 years of age, scheduled for elective surgery were randomly allocated to one of the two groups of 50 patients each. ⋯ Furthermore these changes persisted for longer duration after endotracheal intubation in comparison to LMA insertion (5 min vs 3 min). Incidence of postoperative complications i.e. bronchospasm, laryngospasm and soft tissue trauma was significantly higher (p<0.05) after endotracheal intubation as compared to LMA insertion. To conclude, the laryngeal mask airway is a suitable alternative to endotracheal intubation for positive pressure ventilation in children.

The aim of the study was to assess and compare laryngoscopic view of Truview evo2 laryngoscope with that of Macintosh laryngoscope in patients with one or more predictors of difficult intubation (PDI). Moreover ease of intubation with Truview evo2 in terms of absolute time requirement was also aimed at. Patients for elective surgery requiring endotracheal intubation were initially assessed for three PDI parameters - modified Mallampati test, thyro-mental distance & Atlanto-occipital (AO) joint extension. ⋯ Intubation with Truview evo2 was possible in 88% cases within stipulated time of one minute and mean time of 28.6 seconds with SD of 11.23 was reasonably quick. No significant complication like oro- pharyngeal trauma or extreme pressor response to laryngoscopy was noticed. To conclude, Truview evo2 proved to be a better tool than conventional laryngoscope in anticipated difficult situations.
