Article description
Summary:
- The meta-analysis aim was to determine the efficacy of Phrenic Nerve Infiltration (PNI) as the analgesia method to reduce Ipsilateral Shoulder pain (ISP) following thoracic surgery;
- Systematic review and meta-analysis of randomised controlled trials;
- The study included 6 RCTs with a study population size of 482 patients, four low and two uncertain risks of bias;
- Primary outcomes showed a significantly lower overall risk ratio (RR) of ISP in the PNI group than in the control group (RR: 0.46, 95% CI: 0.34-0.61, p < 0.00001, I2 = 19% p = 0.29);
- Subgroup analysis showed no significant difference between approaches of thoracic surgeries or local anaesthetics on the incidence of ISP;
- Secondary outcomes revealed a significantly lower incidence of ISP in the PNI group than in the control group at postoperative 6, 24, and 48 hours.
Conclusions:
- Phrenic nerve infiltration before chest closure reduces the incidence and severity of ipsilateral shoulder pain;
- Further studies are needed to determine the benefits and risks for patients with impaired pulmonary function.
