Study of lung protection during the total correction of tetralogy of Fallot through right minithoracotomy approach

Objective: To reinforce lung protection during the total correction of tetralogy of Fallot (TOF) through right minithoracotomy approach. Methods: 58 young children with TOF were divided into the control group (n=40) and lung protection group (n=18) . The patients in control group were totally corrected through mediam sternotomy. The patients in lung protection group were totally corrected through right minithoracotomy and lung protection during operations was reinforced by perfusing pulmonary artery with hypothermic protective solution. Patients' hemodynamics and lung functions( oxygen index, P A a O 2,airway pressure)were monitored and plasma MDA were measured. Results: The time of mechanical ventilation and ICU stay were shorter in lung protection group than in control group(P0 05). The airway pressure after operations were not different between both groups (P0 05). The P A a O 2 in lung protection group was lower than in control group at 24 hours and 48 hours after operations (P0 05). The oxygen index in lung protectin group was higher than in control group at 12 hours and 24 hours after operations (P0 05). MDA was lower in lung protection group when compared with control group at 24 hours and 48 hours after operations (P0 01). Conclusion: Reinforcing lung protection during operation could reduce lung injury during the total correction of tetralogy of fallot through right minithoracotomy approach.
