Sir,
Immediate postoperative care of patients undergoing nasal surgery, e.g. septoplasty or rhinoplasty, could be hazardous as desaturation happens frequently, especially if the patient has not fully recovered and is struggling for nasal breathing while the nose is packed with gauze. [1],[2] Moreover, ice might be applied to the nose in the operating room to decrease swelling and an external splint could be taped by the surgeon onto the patient's face. [3] All these make it difficult to apply and fit a Hudson recovery face mask in the postanaesthesia care unit (PACU) to maintain adequate oxygenation. Facing this problem, we prepared an oral oxygenating airway device to maintain an open unblocked airway in addition to adequate oxygenation in the early recovery period for patients undergoing nasal surgery. Our device [Figure 1] is an oral airway size 4 or 5 with a silconized soft endotracheal tube (ETT) size 5.5 mm fixed alongside the airway with its bevel directed laterally to provide easy insertion of the airway. The distal end of ETT is cut 4-5 cm from the airway to be connected to a breathing circuit through 15 mm connector or connected directly to tubing of oxygen flow meter supplying humidified oxygen at low flow rate of 1-2 L/minute to provide FIO 2 35-40%. This device was tried successfully in 54 patients scheduled for septoplasty and rhinoplasty. In conclusion, this device is simple, cheap, easily inserted, efficiently maintains adequate arterial oxygen saturation as long as the oral airway is tolerated in the early recovery period, reduces the oxygen flow rate and in addition, an oxygen analyzer can be connected to the 15 mm connector to provide monitoring of the delivered FIO 2 .
