About this study

Patients undergoing laparoscopic surgery will be randomly assigned either volume controlled ventilation group or pressure controlled volume guaranteed ventilation group. All patients will be performed lung ultrasonography pre and postoperatively to evaluate the development of lung atelectasis and effect of different ventilation modalities on the development of atelectasis.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • undergoing laparoscopic surgery
  • ASA Status I-II

Exclusion criteria

  • Gastroesophageal reflux
  • obstructive sleep apnea syndrome
  • BMI>30
  • severe lung and heart disease
  • ASA Status III-IV

Treatment and study plan

VCV

Procedure

after induction for anesthesia patients will be supported by mechanical ventilation on volume controlled ventilation mode

PCV-VG

Procedure

after induction for anesthesia patients will be supported by mechanical ventilation on pressure controlled and volume guaranteed ventilation mode

Lung ultrasonography

Diagnostic Test

all patients will be performed lung ultrasonography pre and postoperatively

Primary outcomes

  1. Effect of different ventilation mods on development of peroperative atelectasis

    Time frame: at minute 5 in postoperative care unit

    Patients undergoing laparoscopic surgery will be assigned either volume controlled mode or pressure support volume guaranteed mode. After the operation a researcher will perform lung ultrasonography postoperative at minute 5. Researcher will detect 6 region of each lung totally 12 regions . The researcher will record the modified and original lung ultrasonography scores (LUS Score) of the patients. LUS Score is a scoring system to evaluate atelectasis of lung and scores 1-3 points for each region (Min score 0 max score 36)

Secondary outcomes

  1. Effect of different ventilation mods on development of peroperative atelectasis

    Time frame: at minute 30 in postoperative care unit

    Patients undergoing laparoscopic surgery will be assigned either volume controlled mode or pressure support volume guaranteed mode. After the operation a researcher will perform lung ultrasonography in postoperative care unit at minute 30. Researcher will detect 6 region of each lung totally 12 regions . The researcher will record the modified and original lung ultrasonography scores (LUS Score) of the patients. LUS Score is a scoring system to evaluate atelectasis of lung and scores 1-3 points for each region.(Min score 0 max score 36)
