Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Abstract</title> <p>This study aimed to investigate the usefulness of intraluminal PCO<sub>2</sub> (PiCO<sub>2</sub>) monitoring by air tonometry for the assessment of the vascular condition of the transferred jejunum after surgery for hypopharyngeal cancer.</p> <p>PiCO<sub>2</sub> in the transplanted jejunum of 24 patients was monitored using air tonometry after radical surgery for hypopharyngeal cancer from 2003 to 2010.</p> <p>All but 1 patient, who removed the catheter before monitoring began, were monitored safely. PiCO<sub>2</sub> in the transferred jejunum correlated with arterial PCO<sub>2</sub> (PaCO<sub>2</sub>) that was measured concurrently, and dissociation of PiCO<sub>2</sub> from PaCO<sub>2</sub> was observed in cases with vascular complication. In those cases without postoperative vascular complication, the PiCO<sub>2</sub> value gradually increased for 3 hours but then decreased by 12 hours after surgery. Three patients experienced major vascular complication. All 3 patients had continuous elevation of PiCO<sub>2</sub> >100 mm Hg, although vascular flow in 1 patient recovered by removal of a venous thrombosis and reanastomosis of the vein 7.5 hours after surgery. Four other patients who experienced elevation of PiCO<sub>2</sub> had their skin suture released for decompression of their neck wound, resulting in a decrease in PiCO<sub>2</sub> after treatment.</p> <p>The current results demonstrated that continuous monitoring of PiCO<sub>2</sub> by air tonometry accurately reflects the vascular condition of the transferred jejunum, and this method is one of the best options for postoperative monitoring of jejunum blood perfusion.</p> </sec> </abstract>
