ABSTRACT
Visual loss occurring after pediatric cardiac surgery employing cardiopulmonary bypass (CPB) is relatively rare but the risk is substantial. Compromised cerebral perfusion due to a CPB related micro-embolization and inflammatory vascular changes as well as reduced oxygen carrying capacity in hemodilution and hypothermia during CPB might be major contributing factors to the development of postoperative visual loss after cardiac surgery with CPB. A case of immediate but transient postoperative visual loss was encountered in a 21-month-old male who underwent tricuspid valve surgery. Despite routine intraoperative measures to maintain an adequate perfusion pressure throughout the procedure, postoperative computed tomography revealed a subacute infarct in his occipital lobe. Recovery began on postoperative day 28, and the patient's vision was restored by 31 days.

Post-thyroidectomy hematoma is a rare complication, but this complication is potentially life threatening and unpredictable.This complication requires emergency tracheal intubation, which is often difficult because of swollen tissues, poor visualization of the glottis and the distorted airway anatomy.Using the direct laryngoscopy with a Macintosh laryngoscope, we were unable to see even the epiglottis.Pentax-AWS (Pentax-AWS(R), Pentax, Japan) is a new video laryngoscope that provides an indirect view of the glottis and it has a tube channel in the right side of the blade.We were able to fully view larynx with a Pentax-AWS, and then we intubated the trachea immediately and easily.The Pentax-AWS could be a useful alternative device that overcomes the above mentioned difficulties.
