ObjectivesThe effect of ultrasound-guided Erector Spinae Plane block (ESPB) on the time to extubation is unclear. This study aimed to assess the effect of ultrasound-guided bilateral ESPB on the time to extubation in patients who had cardiac surgery through midline sternotomy. DesignRandomized controlled trial. SettingCairo university hospital and national heart institute, Egypt. ParticipantsPatients aged from 18-70 years old who underwent cardiac surgery procedure through midline sternotomy. InterventionsRecruited patients were randomized to receive either preoperative single shot ultrasound guided bilateral ESPB or fentanyl infusion. MeasurementsThe primary outcome was the time to extubation. other outcomes included: total perioperative fentanyl consumption, pain score using the numerical rating score (NRS), length of ICU stay and incidence of perioperative complications. Main resultsTwo hundred and nineteen patients were available for final analysis. In the ESPB group, the mean time of extubation was significantly shorter (159.5 ± 109.5) minutes, compared to the control group (303.2 ± 95.9) minutes, mean difference (95% CI): -143.7(-171.1, -116.3) minutes, p= 0.0001. Ultrafast track (immediate postoperative) extubation was achieved in 23 (21.1%) patients in ESPB group compared to one patient (0.9%) in the control group. The ICU stay was significantly reduced in the ESPB group (47.2 2 ± 13.3) hours compared to the control group (78.9 ± 25.2) hours, p= 0.0001. There was significant reduction in NRS in ESPB group than control group for up to 24 hours postoperatively, p =0.001. ConclusionAmong adult patients undergoing cardiac surgery through medline sternotomy, the extubation time was halved in patients who received single shot bilateral erector spinae plane block compared to patients who received fentanyl infusion.
