Both MAP 1 and MAP2were reduced after sympahtectomy (P < 0.05). Heart rate was reduced transiently after the sympahtectomy and returned to the baseline value. PaO2 was reduced in 10 min after each right lung ventilation (P < 0.05) and left lung ventilation (P < 0.05).
Since thoracoscopic sympathectomy can rarely cause a significant decrease of MAP, cardiac arrythmia, cardiac arrest and hypoxemia, we concluded that invasive BP monitoring should be used for early detection of those complications and immediate arterial sampling.
