- Pain perception after lung cancer surgery was significantly greater in obese patients than in their nonobese counterparts.
- Effect was observed with video-assisted thoracic surgery (VATS) and open thoracotomy.
Why this matters
- Prior studies suggest that chronic pain occurs 4 times more frequently in morbidly obese people compared with those who are not obese.
- 50 obese and 62 nonobese patients underwent lung cancer surgery.
- Funding: Russian Academic Excellence project.
- Patients who reported severe pain (visual analog scale [VAS], >4) had higher BMI (31.8±5.6 vs 28.8±5.2 kg/m2; P<.01 and a longer length of stay vs days p>
- Pain intensity immediately after surgery and at discharge was greater in obese patients compared with overweight patients (P<.0001 for both in overweight patients compared with normal weight and underweight greater obese>
- Pain intensity was greater in obese patients compared with nonobese patients for both VATS and open thoracotomy.
- Patients with VAS >4 immediately after surgery continued to report severe pain at discharge.
- Retrospective, single-center study.
