Ultrasonography, Postoperative Complications, Anesthesia, Surgery-Complications, Pulmonary Complication
Conditions
Brief summary
Patients undergoing surgery inside their abdomen, with no serious heart or lung diseases, will have a lung ultrasound exam before and after surgery. The patient respiratory status in the post-operative unit and the surgical ward will be monitored for complications after surgery
Detailed description
The study will be performed in the Soroka hospital operating room and recovery unit. On admission to pre-surgery, patients will be investigates for inclusion and exclusion criteria. Those that are eligible for the study will be asked to give formal consent to participate in the study. After consent the examiner will review the patient's past medical history and surgery plan, and will preform the pre-operative LUS exam. After surgery, the examiner will review the electronic anesthesia record and will preform the post-operative LUS exam within 30 minutes of arrival to the recovery unit or 30 minutes from extubation (in patients that were admitted to the recovery unit still under mechanical ventilation). Upon discharge from the recovery unit the examiner will review the recovery unit electronic record. After discharge, the examiner will review the patient post-operative surgical ward electronic record.

Patients who require un-planned long term mechanical ventilation or those who died during surgery will also be excluded.
