Description of intervention(s) / exposure
All patients having elective open hernia repairs, prolonged (>180mins) laparoscopic upper abdominal surgery or prolonged (>180mins) lower abdominal abdominal surgery at two Tasmanian hospitals will be be assessed prospectively and daily for the first 14 postoperative days or up to day of discharge, whichever occurs first. Patients will be screened for a postoperative pulmonary complication and prolonged postoperative paralytic ileus using standardized diagnostic screening tools.
A postoperative pulmonary complication will be assessed using the Melbourne Group Score Version 3. A positive diagnosis is determined when any four or more of the following criteria; abnormal auscultation, purulent sputum, oxygen desaturation <90% on room air, temperature >38°C, chest imaging of collapse/consolidation, white cell count >11, positive sputum culture, or physician diagnosis or prescription of antibiotics specific for a respiratory infection, are present in a calendar day. A prolonged paralytic ileus was detected when two or more of the following criteria; nausea or vomiting, unable to tolerate oral diet, absence of flatus, abdominal distension, radiological report of gastrointestinal obstruction or ileus, or doctor diagnosis of ileus, occurred in a calendar day on or after the 4th postoperative day.

Summary
Brief summary
Respiratory complications are reportedly very low (<2%) following open incision lower abdominal surgery and simple laparoscopic upper gastrointestinal surgery (e.g. lap choles). Due to a high cost to benefit ratio, prophylactic physiotherapy directed respiratory exercises and assisted early ambulation is not provided to these patients over and above standard ward care in a majority of hospitals in Australia or Europe. However as more complex procedures, such as bowel resections are increasingly being performed, the corresponding operation times are extending well past 3 hours. This may independently increase the risk of a respiratory complication. However, reports on respiratory complications in prolonged (>3r) laparoscopic and open lower abdominal is lacking. This trial aims to measure rates of respiratory complications in this population in the context of standard hospital ward care. Risk prediction modelling of those patients at highest risk will ensure that future prophylactic delivery of respiratory exercises and Physiotherapy is targeted to those patients that most require them.
