RESUMO
BACKGROUND AND OBJECTIVES: The primary aim of this study is to assess the effect of ultrasoung-guided erector spinae block on postoperative opioid consumption after laparoscopic cholecystectomy. The secondary aims are to assess the effects of erector spinae plane block on intraoperative fentanyl need and postoperative pain scores. METHODS: Patients between 18-70 years old, ASA I-II were included in the study and randomly allocated into two groups. In Group ESP, patients received bilateral US-ESP with 40ml of 0.25% bupivacaine at the level of T7, while in Group Control, they received bilateral US-ESP with 40ml of saline before the induction of anesthesia. Then a standard general anesthesia procedure was conducted in both groups. NRS scores at the postoperative 15th, 30th, 60th minutes, 12th and 24th hours, intraoperative fentanyl need and total postoperative tramadol consumption were recorded. RESULTS: There were 21 patients in Group ESP and 20 patients in Group Control. Mean postoperative tramadol consumption was 100±19.2mg in Group ESP, while it was 143±18.6mg in Group Control (p<0.001). The mean intraoperative fentanyl need was significantly lower in Group ESP (p=0.022). NRS scores at the postoperative 15th, 30th min, 12th hour and 24th hour were significantly lower in ESP group (p<0.05). According to repeated measures analysis, NRS score variation over time was significantly varied between two groups (F[1,39]=24.061, p< 0.0005). CONCLUSIONS: Bilateral US-ESP block provided significant reduction in postoperative opioid consumption, intraoperative fentanyl need and postoperative pain scores of patients undergoing laparoscopic cholecystectomy.

Resumo Justificativa e objetivos: O objetivo primário deste estudo foi avaliar o efeito do bloqueio do plano do músculo eretor da espinha guiado por ultrassom (US-ESP) sobre o consumo de opioides no pós-operatório após colecistectomia laparoscópica. Os objetivos secundários foram avaliar os efeitos do bloqueio do plano eretor da espinha sobre a necessidade de fentanil no intraoperatório e nos escores de dor pós-operatória. Métodos: Pacientes entre 18 e 70 anos, ASA I-II, foram incluídos no estudo e alocados randomicamente em dois grupos. No Grupo ESP, os pacientes receberam o bloqueio bilateral US-ESP com 40 mL de bupivacaína a 0,25% no nível de T7, enquanto no Grupo Controle os pacientes receberam o bloqueio bilateral US-ESP com 40 mL de solução salina antes da indução da anestesia. Em seguida, um procedimento-padrão de anestesia geral foi feito em ambos os grupos. Os escores da NRS aos 15, 30 e 60 minutos e em 12 e 24 horas de pós-operatório, a necessidade de fentanil no intraoperatório e o consumo total de tramadol no pós-operatório foram registrados. Resultados: O grupo ESP foi constituído por 21 pacientes e o Grupo Controle por 20. O consumo médio de tramadol no pós-operatório foi de 100 ± 19,2 mg no Grupo ESP e de 143 ± 18,6 mg no grupo controle (p < 0,001). A necessidade média de fentanil no intraoperatório foi significativamente menor no grupo ESP (p = 0,022). Os escores da NRS aos 15, 30 e 60 minutos e em 12 e 24 horas de pós-operatório foram significativamente menores no grupo ESP (p < 0,05). De acordo com a análise de medidas repetidas, a variação do escore NRS ao longo do tempo foi estatisticamente significativa entre dois grupos (F [1,39] = 24,061, p < 0,0005). Conclusões: O bloqueio bilateral US-ESP reduziu de forma significativa o consumo de opioides no pós-operatório, a necessidade de fentanil no intraoperatório e os escores de dor no pós-operatório dos pacientes submetidos à colecistectomia laparoscópica.
