Brief Summary:
Perioperative airway resistance and lung function are evaluated perioperatively in patients, who undergo surgical procedures in different postures and with or without gas insufflation into the peritoneal cavity.

Condition or disease

Detailed Description:
Lung function, upper and lower airway resistance measurements are performed in patients in prone horizontal or head tilted down (40°) position. Half of the patients with head down position will have surgery in laparoscopic technique (including gas insufflation to achieve a pneumoperitoneum). Measurements are performed on the day prior to surgery, on the morning of surgery, 30 - 45 minutes, 2 hours, and 24 hours after extubation.

Primary Outcome Measures :
  1. Measurement of FEV1 (forced expiratory volume in one second) and the MEF50/MIF50 ratio [ Time Frame: 18 months ]

Secondary Outcome Measures :
  1. Changes in nasal airway resistance [ Time Frame: 18 months ]
