COMPARISON OF ERECTOR SPINAE PLANE BLOCK & CONVENTIONAL ANALGESIC TECHNIQUE FOR POSTOPERATIVE PAIN RELIEF IN CAESAREAN SECTION – A PROSPECTIVE RANDOMISED STUDY

Abstract

Background: Postoperative pain relief after caesarean delivery is challenging because it needs to provide maternal satisfaction while having no adverse effects on the baby. The study aimed to compare the analgesic efcacy of bilateral ESP block with that of conventional technique after elective LSCS under SAB. In this single blind randomized, prospective comparative Methods: study, 76 healthy parturient were randomly divided into two groups. Group1 received bilateral ESPB using 0.2% ropivacaine (0.2ml/kg) before spinal anaesthesia, Group 2 received conventional postoperative analgesics on patient's demand. The duration of postoperative analgesia and VAS pain score was recorded for 24hrs. Onset & duration of sensory and motor block, hemodynamic parameters and adverse effects were assessed. Data analysis was done with statistical software SPSS Version. 24 with Unpaired T test and Chi-square test. The duration of anal Results: gesia (152.55 ± 64.46mins vs 96.68 ± 36.09mins) was signicantly prolonged in Group ESPB than Group Control (P<0.0001) The mean VAS score was signicantly less in ESPB group at 2hr (P value =0.0243), 12hr (P value = 0.0250) and 24hrs (P value = 0.0408) postoperatively. ESPB group of patients require less analgesic dose of inj. Tramadol (P= 0.0389), inj. Diclofenac sodium (P <0.0001) and inj. Paracetamol (P= 0.0423) as compared to that of Control group with signicant difference. Onset of sensory and motor block was signicantly faster in ESPB Group than Control Group. ESP block provides more effective Conclusion: pain relief, longer duration of analgesic action, prolongs time to rst analgesic requirement, associated with less consumption of conventional analgesics and also potentiates the onset of sensory and motor block.
