Laryngeal mask airway (LMA) has become a standard device in the spectrum of gadgets for airway management. Intubating laryngeal mask airway (ILMA ® , LMA-fastrach ® ) is one of them. It was designed to overcome few difficulties of LMA-classic ® during tracheal intubation. , After the trachea is intubated successfully through ILMA, it is usually recommended to remove the ILMA. , The tracheal tube needs to be stabilized to prevent extubation during ILMA removal. A stabilizer rod (introducer, extender) is placed at the end of the tracheal tube and pushed inside while the ILMA is withdrawn. It is supplied along with the ILMA device. The initial price of ILMA is very high (Rs. 30,000 approximately). If it is used number of times, it becomes a cost effective choice. However, during repeated attempts of packing and sterilization, the stabilizer rod may get lost and rarely get damaged. If so, ILMA cannot be used for intubating purposes. Hence, we developed a stabilizer rod with some cheap disposable items available in the operating room. We successfully used this 'new' stabilizing rod in intubating the trachea.
We took a 6.5 mm internal diameter used red rubber noncuffed tracheal tube (Rusch, W. Germany), cut at 19 cm and then the bevel was also cut to make opening straight [Figure 1]a. A 16 French gauge nasogastric tube was also cut at the 20 cm length, and an old used disposable double lumen endobronchial tube stylet was introduced into the nasogastric tube [[Figure 1]b and c] to make the tube stiff. This unit was introduced into the prepared red rubber tracheal tube [Figure 1]d and the extra portion at the other end was cut [Figure 2]a and fixed with a rubber cap of antibiotic vial [Figure 2]b with adhesive glue. At the projected end, a cut suction catheter connector was inserted with glue ('Fevikwik'). A word of caution is to check the assembly before use for lose components. The extender made like this is comparable with that of the company make [Figure 2]c. This stabilizer (introducer, extender) can be as good as the original one [Figure 2]d. The cost of this is approximately less than Rs. 100 and can be reused number of times after autoclaving along with the ILMA.
