ABSTRACT

Objective:

To evaluate the effect of hydrogen on the occurrence of pulmonary complications after thoracoscopic radical resection of lung cancer.

Methods:

One hundred and ten patients of both sexes, aged 45-75 yr, with body mass index of 18-23 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, scheduled for elective thoracoscopic radical resection of lung cancer, were divided into 2 groups ( n=55 each) using the random number table

method:

hydrogen group (group H) and control group (group C). Patients inhaled 66.7% hydrogen for 60 min before anesthesia in group H, while 33% oxygen was inhaled for 60 min in group C. Blood samples were collected from the radial artery at 5 min before one-lung ventilation (T 0) and 1 h of one-lung ventilation (T 1) for blood gas analysis and for determination of peak airway pressure, airway plateau pressure, driving pressure and dynamic lung compliance.Oxygenation index was calculated.Bronchoalveolar lavage fluid on the ventilated side was collected at T 0 and T 1 for measurment of interleukin-6 concentrations by enzyme-linked immunosorbent assay.The incidence of pulmonary complications within 7 days after surgery was recorded.

Results:

Compared with group C, the oxygenation index and dynamic lung compliance were significantly increased, and the peak airway pressure, airway plateau pressure, driving pressure, interleukin-6 concentrations in bronchoalveolar lavage fluid, and incidence of pulmonary complications within 7 days after surgery were decreased in group H ( P<0.05).

Conclusion:

Hydrogen can decrease the occurrence of pulmonary complications, and the mechanism is related to reducing lung inflammatory responses and improving lung compliance in the patients undergoing thoracoscopic radical resection of lung cancer.
