Abstract:
The problem of respiratory support in tracheal surgery is still discussed in recent days.
Anaesthesiologist must choose the most effective and safe respiratory technique during tracheal resection
and reconstruction. The article deals with a case of comparison of apneic oxygenation (AO) and high
frequency jet ventilation (HFJV) during double level tracheal resection and reconstruction in patient with
multifocal tracheal stenosis and underlying cerebral trauma. Materials and methods: AO and HFJV were
used due to surgical need for 20 min each technique.

fixed before and after the changing of respiratory support type. Additionally peak systolic speed (S) of blood
flow in the a. Cerebralis media sinister was fixed by transcranial Doppler (“Angiodin BIOSS”, Russia).
Results: oxygenation of venous blood was sufficient after the both HFJV and AO use; PvO2 was 67.6 and
74.3 torr respectively. Speed of PvCO2 increasing was higher during AO (1.46 torr per min) than during
HFJV (0.73 torr per min). Increase of S was bigger during AO than HFJV as well (59 vs 37%). The changes
of PvCO2 and S were normalized in 15 min after reconnection to conventional mechanical ventilation. Other
fixed parameters were normal and same during the use of both respiratory techniques. The patient involved
in the study did not have any neurological or surgical complications in early postoperative period.
Conclusions: Both studied respiratory techniques provide sufficient blood oxygenation and can be
accompanied with hypercapnia and cerebral hyperemia. These observations evident about the necessity to
study the role of hyperoxia, hypercapnia and cerebral hyperemia in patients with underlying cerebral trauma
undergoing tracheal resection and reconstruction. The study will help to make a strategy of the foreground
use of HFJV and AO in these patients.
