Consecutive series of patients (n = 210), suffering from upper limb hyperhidrosis, anaesthetised for TES.
SpO2 decreased below 98% in 58 patients. Sudden hypotension and bradycardia in two patients.
The mean PaO2 was significantly (p = 0.03) decreased during two-lung ventilation (TLV), after reinflation of the right lung, compared with TLV after endobronchial intubation. There was no significant difference in mean PaO2 during one-lung ventilation of both lungs. Lowest PaO2 observed during one-lung ventilation was less than 13.3 kPa in three sympathectomies. Postoperative pain, severe on awakening and mainly retrosternal, was relieved with i.v. opiates. CONCLUSION: Controlled ventilation with 100% inspired O2, SpO2 monitoring and one to two gentle manual ventilations when it decreases is the cornerstone of the management of hypoxaemia, a potentially serious complication of TES.
