Does prewarming of i-gel improve insertion and ventilation in anaesthetised and paralysed patients? A prospective, randomised, control trial.

Context: I-gel are supraglottic airway devices with non-inflatable gel-like cuff that is believed to mould to body temperature, to seal the airway. Hence a pre-warmed i-gel may seal faster, provide better ventilation and superior leak pressure.

Aims: To determine if pre-warming i-gel to 40°C improves insertion and efficacy of ventilation.

Apneic Oxygenation during simulated prolonged difficult laryngoscopy: Comparison of nasal prongs versus nasopharyngeal catheter: A prospective randomized controlled study.

Background: Apneic oxygenation by insufflating O2 through nasal prongs (NP) and nasopharyngeal catheter (NC) has been proven to be effective. We conducted this study to compare the relative efficacy of these two techniques in a simulated difficult airway situation.

Objective: The objective of this study is to evaluate the influence of two techniques of apneic oxygenation (NP vs.

Anaesthetic management of a child with congenital afibrinogenemia - A rare inherited coagulation disorder.

Congenital afibrinogenemia is a very rare autosomal recessive disorder, results from mutation that affects plasma fibrinogen concentration. It is frequently associated with bleeding diathesis of varying severity. We describe the case of a 10-year-old child diagnosed of congenital afibrinogenemia who presented to hospital with subperiosteal haematoma and was posted for incision and drainage.

Effect of Supplementing Oxygen with Positive end Expiratory Pressure During Elective Caesarean Section under Spinal Anaesthesia on Foetus.

Background: It is known fact that pre-oxygenation with positive end-expiratory pressure (PEEP) improves the Partial pressure of oxygen (PO (2)). In this regard not many studies have been done in pregnant women to know its effect on foetus. In this randomised double blind controlled study, we analysed effect of pre-oxygenation with PEEP during caesarean section on foetal umbilical venous PO (2).

The effect of ephedrine on intubating conditions and haemodynamics during rapid tracheal intubation using propofol and rocuronium.

Background: We compared the effect of pre-treatment with ephedrine 75, 100, 150 microg kg(-1) and saline on intubating conditions and haemodynamics during rapid tracheal intubation using propofol and rocuronium.

Methods: One hundred adult patients randomized into one of the four groups-PE 75, PE 100, PE 150, and saline (control) groups-were pre-treated with i.v.
