Abstract

This study aimed to compare the analgesic efficacy of the transversus abdominis plane block (TAPB) and the erector spinae plane block (ESPB) following cesarean delivery under spinal anesthesia. The primary endpoint was the proportion of patients requiring rescue analgesia within the first 24 hours postoperatively. Secondary outcomes included time to first rescue analgesia, Numerical Rating Scale (NRS) scores at predefined time points (30 minutes, 4, 8, 12, 16, and 24 hours), and the incidence of persistent postsurgical pain at two months. METHODS: This single-center, prospective, randomized controlled study included patients undergoing cesarean section under spinal anesthesia. Participants were randomly allocated into two groups: TAPB and ESPB. Postoperative pain and vital signs were assessed 30 minutes after block application and at 4, 8, 12, 16, and 24 hours postoperatively. Pain intensity was measured using the NRS (0=no pain, 10=worst imaginable pain). Rescue analgesia was administered when the NRS score was &#x2265;4. Diclofenac sodium 75 mg intramuscularly (IM) was given for NRS scores of 4-5, while intravenous (IV) morphine sulfate 0.05 mg/kg was administered for NRS scores &#x2265;6. RESULTS: A total of 94 patients were analyzed: 48 received ESPB and 46 received TAPB postoperatively. The TAPB group had a significantly higher proportion of patients requiring rescue nonsteroidal anti-inflammatory drug (NSAID) analgesics compared to the ESPB group (58.70% vs. 27.08%, p=0.002). NRS scores at 30 minutes, 12 hours, and 16 hours postoperatively were significantly lower in the ESPB group (p=0.03, p=0.003, and p=0.023, respectively). CONCLUSION: For postoperative analgesia following cesarean section under spinal anesthesia, ESPB resulted in a significantly lower proportion of patients requiring rescue analgesia within the first 24 hours compared to TAPB. In addition, ESPB demonstrated a faster onset and longer duration of effective analgesia, suggesting it may be a more favorable option for postoperative pain management in this clinical setting. AMA&#xc7;: Bu &#xe7;al&#x131;&#x15f;ma, spinal anestezi alt&#x131;nda ger&#xe7;ekle&#x15f;tirilen sezaryen do&#x11f;umu sonras&#x131;nda transversus abdominis plan blo&#x11f;u (TAPB) ile erector spinae plan blo&#x11f;u (ESPB) uygulamalar&#x131;n&#x131;n analjezik etkilerini kar&#x15f;&#x131;la&#x15f;t&#x131;rmay&#x131; ama&#xe7;lamaktad&#x131;r. Birincil sonlan&#x131;m noktas&#x131;, postoperatif ilk 24 saatte kurtarma analjezisi gereksinimi duyan hasta oran&#x131;d&#x131;r. &#x130;kincil sonlan&#x131;m noktalar&#x131; aras&#x131;nda ilk kurtarma analjezisine kadar ge&#xe7;en s&#xfc;re, belirli zaman noktalar&#x131;ndaki NRS skorlar&#x131; (30. dakika, 4., 8., 12., 16. ve 24. saatler) ve 2. ayda persistan cerrahi sonras&#x131; a&#x11f;r&#x131; insidans&#x131; yer almaktad&#x131;r. GERE&#xc7; VE Y&#xd6;NTEM: Bu tek merkezli, prospektif randomize kontroll&#xfc; &#xe7;al&#x131;&#x15f;ma, spinal anestezi alt&#x131;nda sezaryen operasyonu ge&#xe7;iren ve rastgele iki gruba (TAPB ve ESPB) ayr&#x131;lan hastalar&#x131; i&#xe7;ermektedir. Postoperatif a&#x11f;r&#x131; ve vital bulgular, blok sonras&#x131; 30. dakikada ve postoperatif 4., 8., 12., 16. ve 24. saatlerde de&#x11f;erlendirilmi&#x15f;tir. A&#x11f;r&#x131;, say&#x131;sal derecelendirme skoru (NRS; 0: a&#x11f;r&#x131; yok, 10: en &#x15f;iddetli a&#x11f;r&#x131;) ile &#xf6;l&#xe7;&#xfc;lm&#xfc;&#x15f;t&#xfc;r. NRS skoru 4 veya daha y&#xfc;ksek olan hastalara kurtarma analjezisi uygulanm&#x131;&#x15f;t&#x131;r. NRS skoru 4 veya 5 olan hastalara 75 mg IM diklofenak sodyum, 6 ve &#xfc;zeri olanlara ise 0.05 mg/kg IV morfin s&#xfc;lfat verilmi&#x15f;tir. BULGULAR: &#xc7;al&#x131;&#x15f;mada toplam 94 hasta analiz edilmi&#x15f;tir: 48 hastaya postoperatif ESPB, 46 hastaya TAPB uygulanm&#x131;&#x15f;t&#x131;r. &#x130;lk 24 saatte kurtarma NSA&#x130; analjezik ihtiyac&#x131; TAPB grubunda anlaml&#x131; derecede daha y&#xfc;ksek bulunmu&#x15f;tur (%58.70&#x2019;e kar&#x15f;&#x131; %27.08, p=0.002). ESPB grubunda 30. dakika, 12. saat ve 16. saatteki NRS skorlar&#x131; anlaml&#x131; olarak daha d&#xfc;&#x15f;&#xfc;k bulunmu&#x15f;tur (s&#x131;ras&#x131;yla, p=0.03, p=0.003 ve p=0.023). SONU&#xc7;: Spinal anestezi alt&#x131;nda ger&#xe7;ekle&#x15f;tirilen sezaryen operasyonlar&#x131;nda postoperatif analjezi i&#xe7;in uygulanan ESPB, TAPB&#x2019;ye k&#x131;yasla ilk 24 saatte kurtarma analjezisi gereksinimi duyan hasta oran&#x131;n&#x131; anlaml&#x131; derecede azaltm&#x131;&#x15f;t&#x131;r. Ayr&#x131;ca ESPB, daha h&#x131;zl&#x131; ba&#x15f;layan ve daha uzun s&#xfc;ren etkili analjezi sa&#x11f;lam&#x131;&#x15f; ve bu y&#xf6;n&#xfc;yle postoperatif a&#x11f;r&#x131; y&#xf6;netiminde daha avantajl&#x131; bir se&#xe7;enek oldu&#x11f;unu desteklemi&#x15f;tir.
