IntroductionAcute ipsilateral shoulder pain (ISP) is a common complaint in patients after thoracotomy. The incidence ranges from 21% to 97%. Unfortunately, clinical studies did not put enough focus on ISP post thoracic surgery.Aim of the workThis study was designed to compare the effectiveness of suprascapular nerve block (SNB) and phrenic nerve infiltration (PNI) for controlling ISP.Patients and methodsOne hundred and thirty-five lung cancer patients (135) scheduled for open-lung surgery were randomly allocated into three equal groups; control group: received thoracic epidural with general anesthesia, suprascapular group: (SNB) one hour before the operation with 10 ml bupivacaine plus thoracic epidural with general anesthesia and phrenic nerve group: (PNI) was performed by the operating surgeon with 10 ml bupivacaine plus thoracic epidural with general anesthesia.The visual analogue score (VAS) of ISP, rescue of ketorolac for break through shoulder pain, peak expiratory flow rate (PEFR) and arterial blood gases were measured every 6 h postoperatively for 48 h.ResultsThe VAS, rescue doses of ketorolc and PEFR were significantly lower in the phrenic nerve group (P-value <0.05). There was no statistically significant difference between the three groups postoperatively as regards arterial blood gases (P-value >0.05).ConclusionPNI is more effective than SNB for ISP.
