Objectives:
Recently a biocompatible bone adhesive was introduced in addition to the sternal wires to expedite sternal union and improve patient recovery. In this study we aim to objectively assess the biomarker of pain in patient who received the biocompatible bone adhesive.
Methods:
A total of 62 patients who underwent sternotomy were prospectively randomised to receive either conventional wire closure (CWC); 32 patients or adhesive enhanced closure in addition to sternal wire (AEC); 30 patients. Patients were monitored postoperatively at certain time intervals for incisional pain, serum Interleukin-6 (IL-6) level, analgesia used and postoperative complications. All patients were followed up for 4 weeks.
Results:
The post-operative pain scores with coughing were significantly higher in the CWC group at 24 hours and 48 hours. The postoperative IL 6 levels were significantly higher in the CWC group in comparison with the AEC group at 6 hours, 24 hours, and 48 hours. There were no significant differences in term of additional analgesia used. No adverse events from adhesive bone cement were observed during follow up.
Conclusions:
Adhesive-enhanced sternal closure resulted in modest reduction of pain confirmed by reduction of pain biomarker. Justification of its routine use requires larger multicentre study.
