The Effects of Secondary Smoking During One Lung Ventilation
The Effects of Secondary Smoking During One Lung Ventilation
Smoking and perhaps secondary smoking is associated with many perioperative and postoperative
 complications, especially respiratory events. Hypoxemia and airway damage can be associated
 with secondary smoking. The aim of study is to predict the incidence of hypoxemia and airway
 damage during one lung ventilation for lobectomy.
Sixty patients undergoing lobectomy using one lung ventilation by double lumen tube will be
 included in this study. These patients will be divided into 2 groups. Groups S which will be
 included non smoking and secondary smoking and group SS which will be included secondary
 smoking ( smoking near him more than 10 cigarettes per day fore more than 5 years). Intra and
 postoperative arterial oxygen tension, arterial carbon dioxide tension and intraoperative
 peak airway pressure will be compared between the two groups.
Inclusion Criteria:

 -  Sixty patients undergoing lobectomy using one lung ventilation by double lumen tube,
 ASA physical status 2 and 3.

 Exclusion Criteria:

 -  Recent chest infection, morbid obesity, renal, hepatic and ischemic hearts disease,
 asthma.
