The Effect of High Frequency Jet Ventilation (HFJV)During Laparoscopic Operations

The Effect of High Frequency Jet Ventilation (HFJV)on Pneumoperitoneum Induced Cardiovascular Changes, During Laparoscopic Surgery.

Investigators conducted a randomised perspective study to determine whether the use of HFJV instead of conventional mechanical ventilation will reduce the adverse cardiovascular effects of pneumoperitoneum during laparoscopic surgery.

Inclusion Criteria:

• Healthy patients, undergoing laparoscopic surgery for Symptomatic cholecystolithiasis.
