Submental tracheal intubation in a case of panfacial trauma.

Airway management of panfacial fractures is complicated. Treatment of fractures of such bones presents a certain difficulty as in not only do the fracture fragments have to be aligned but the teeth have to be kept in proper occlusion as well. To achieve a proper pre-traumatic occlusion, the occlusion has to be maintained and checked at all times during the surgery. There are many options for the airway management of such cases. We present a case of panfacial fracture which was managed successfully with submental intubation.

Diagnosis of aortic occlusive diseases using impedance plethysmography.

Impedance plethysmographic observations have been correlated with aortographic observations in 57 patients suspected of aortic occlusive diseases. Aortic occlusions have been characterised by marked decrease in blood flow index and significant increase in differential pulse arrival time at thigh level bilaterally. Atherosclerotic affection of the aorta has been featured by a bilateral decrease in the value of blood flow index as well as differential pulse arrival time at thigh level. Leriche's syndrome, however, has been found to decrease the blood flow index moderately at thigh in both the legs without any significant change in differential pulse arrival time. Aortography in all the patients has confirmed the diagnosis made by impedance plethysmography.
