New Research Protocol Aims to Reduce Lung Complications After Abdominal Surgery Without Drugs

Thousands of people across Kent undergo abdominal surgery each year, and now new research could help them recover more safely. BMJ Latest has highlighted a thorough research protocol that aims to evaluate non-drug interventions designed to prevent postoperative pulmonary complications after abdominal surgery.

The protocol, registered as PROSPERO CRD42025637449, outlines a systematic review and meta-analysis of randomised controlled trials. Researchers will assess single structured non-pharmacological interventions to prevent postoperative pulmonary complications in adults undergoing elective abdominal surgery under general anaesthesia.

What Interventions Are Being Studied

The research focuses on interventions that can be delivered at different stages of a patient’s surgical journey. These include respiratory physiotherapy, incentive spirometry, and early mobilisation programmes.

Some interventions happen before surgery, others during the operation, and some after patients wake up. Each approach will be classified by type and timing to help doctors understand when these techniques work best.

Postoperative pulmonary complications represent a serious concern for surgical teams. They contribute to increased illness and death rates, longer hospital stays, and higher healthcare costs following abdominal surgery.

The Research Approach

The literature search covers major medical databases including Ovid MEDLINE, Embase, and Web of Science from their inception to January 2025. Researchers aren’t restricting their search by language, ensuring they capture relevant studies from around the world.

At the same time, the focus remains firmly on adult patients undergoing planned abdominal procedures. This targeted approach should provide clearer guidance for surgical teams treating similar patient groups.

Non-pharmacological strategies like breathing exercises are often recommended, but there’s been a lack of complete analysis comparing their effectiveness. This research aims to fill that gap by pooling data from recent high-quality randomised controlled trials.

Proven Benefits of Non-Drug Approaches

Related research already shows promising results for non-pharmacological interventions in abdominal surgery patients. Preoperative counselling has demonstrated strong effects on reducing both anxiety and pain.

Data from 35 randomised controlled trials shows preoperative counselling reduces preoperative anxiety with an effect size of -1.36. The same intervention also reduces postoperative anxiety (-1.30) and postoperative pain within 24 hours (-0.84).

These findings suggest that simple, low-cost strategies can make a real difference to patient outcomes without relying on additional medications.

Why This Matters Now

Researchers emphasise the urgent need for rigorous evidence synthesis to optimise perioperative care and support updated clinical guidelines. The protocol aims to inform clinical decision-making and identify gaps where more research is needed.

Clinical practitioners already recognise that non-pharmacological interventions like preoperative counselling show strong effects on related outcomes. The challenge lies in integrating these approaches systematically into routine nursing and medical care.

For patients and the public, this research emphasises practical strategies that could minimise complications, reduce reliance on opioids, and speed recovery times without additional drugs.

Key Takeaways

• New research protocol will systematically review non-drug interventions to prevent lung complications after abdominal surgery
• Interventions include respiratory physiotherapy, incentive spirometry, and early mobilisation delivered before, during, or after surgery
• Previous studies show preoperative counselling markedly reduces anxiety and postoperative pain in surgical patients

What This Means for Kent Residents

Patients facing abdominal surgery at Kent hospitals like East Kent Hospitals University NHS Foundation Trust or Maidstone and Tunbridge Wells NHS Trust could benefit from these evidence-based approaches once the research concludes. NHS Kent and Medway Integrated Care Board may incorporate the findings into local surgical pathways to reduce complications and healthcare costs. If you’re scheduled for abdominal surgery, ask your surgical team about structured non-drug measures like breathing exercises or early mobilisation programmes that might be available to support your recovery.
