LIGHTWAND TRACHEAL INTUBATION

INTRODUCTION :
      Lightwand is a lighted stylet, which uses the trans-illumination as a guide to blind Intubation of the trachea. It is useful in difficult intubation situation and a better choice when compared to Blind nasal intubation where you require a cooperative spontaneously breathing patients and flexible fibreoptic bronchoscope requires a clear field devoid of secretions. The tracklight has a bulb attached at the tip with internal light source/handle along with a retractable stylet. If also has connector clamp which allows for securing of the tube and now provided with three reusable stylets to accommodate tracheal tubes from ID size 2.5 - 10 mm.


BASIC TECHNIQUES:
      The distal end of the stylet should be lubricated with water based surgical lubricant and the tracheal tube threaded onto it. The tube connector should be removed before loading and then reconnected once tracheal intubation is complete. The stylet is then shaped bending it 3 - 6 cm from the distal end to a 90o - 120o "hockey stick" formation.
      The operator has to stand on the head end of the patient, control the tube and the lighted stylet like a pencil grip for oral intubation. The room lights will be put offbefore intubation. The lower jaw will be grasped and pulled forward with adequate mouth opening using the nondominant hand. Holding the handle of the lightwand with the dominant hand, the tip of the lightwand should be passed under the tongue and with gentle anterior traction a bright glow is seen in the anterior neck midline near the thyroid cartilage upto the suprastemal notch. The stylet will be pulled and the endotracheal tube simultaneously slid forward off the stylet.

           In G.H., Pondicherry, we have intubated more than 30 cases with the lightwand the procedure can be easily learnt and is a reliable technique for resident doctors. It has a definitive edge over conventional technique in cases of cervical spine fracture, Pierre robbin syndnome, Tempero mandibular joint immobility etc.,
