Brief Summary

General anaesthesia results in developement of atelectasis in dependent areas of the lungs exposing patients to an increased risk of hypoxaemia.During pelvic robotic surgeries pneumoperitoneum and steep trendelenburg position further increases atelectasis. Lung Ultrasound imaging is a promising , noninvasive , non-radiant, portable tool to study intraoperative lung atelectasis.

Conditions

Atelectasis

Keywords

Lung Ultrasonography; Step Trendelenburg position

Outcome Measures

Primary Outcomes (1)

• To assess the degree of lung atelectasis and aeration score.

  By performing Lung Ultrasonography in six basal zones ( 3 in each lung)

  T1 -Baseline postintubation and before docking robotic arms .T2 - At the end of Robotic surgery upto 6 hours and after removal of robotic arms before extubation.

Secondary Outcomes (3)

• To study the effect of intraoperative Atelectasis on arterial oxygen tension

  T1 - Baseline postintubation and before docking robotic arms , T2 -upto 6 hours of robotic surgery and after removal of robotic arms ..

• To study the effect of intraoperative atelectasis on Alveolar- arterial Oxygen Gradient

  T1 - Baseline postintubation and before docking robotic arms , T2 -upto 6 hours of robotic surgery and removal of robotic arms before extubation.

• To study the effect of mode of ventilation on intraoperative atelectasis

  T1 Baseline T2 Upto 6 hours of Robotic surgery

Study Arms (2)

Lung Ultrasonography prior to docking Robotic arms

Base line Lung ultrasonography will be performed in three basal zones for Right and Left lung -Post intubation and prior to docking robotic arms .

Diagnostic Test: Lung Ultrasonography (Baseline)

Lung Ultrasonography after removal of robotic arms

Lung Ultrasonography will be performed to assess degree of atelectasis after removal of robotic arms and before extubation in three basal zones for Right and Left lung .

Diagnostic Test: Lung Ultrasonography ( At the end of surgery)

Interventions

Lung Ultrasonography (Baseline) DIAGNOSTIC_TEST

Lung Ultrasonography will be performed prior to docking Robotic arms in basal three lung zones on both sides.
