Erector spinae block (ESPB) is an effective therapy for chronic shoulder pain. However, ESPB has not been used as a postoperative analgesia method in shoulder surgeries. In this case report, we report three patients undergoing shoulder surgeries that received ESPB preoperatively for postoperative analgesia. All patients had relief of preoperative pain and no associated motor block. Two of the patients manifested with low maximum pain scores (4/10, 3/10) on a numeric rating scale (NRS). The other patient reported a maximum pain score of 8/10 on NRS. While this patient's shoulder mobility immediately improved after ESPB application, the ESPB did not provide adequate analgesia for the postoperative period. The use of the ESPB for acute postoperative analgesia after shoulder surgery is novel and clinically interesting. However, postoperative analgesia was not completely opioid-sparing. Consequently, the efficiency of ESPB at the level of T2 for postoperative analgesia should be considered for surgeries that involve the shoulder cap given the possible inadequate migration of local anesthetic into the cervical plexus. Clinicians should carefully consider an ESPB as a postoperative analgesic option when considering shoulder operations and the possibility for the incomplete spread of local anesthetic in targeted neural structures., Competing Interests: The authors have declared that no competing interests exist.

Regional anesthesia is a widely used anesthesia technique for high-risk patients with severe vascular or pulmonary diseases in which general anesthesia is considered harmful and should be avoided. In this case, we present the use of femoral-sciatic nerve block combination for a 65-year-old, ASA IV, male patient who had severe emphysematous lung disease and was planned for a right femoral-popliteal arterial bypass surgery. He had severe pulmonary disease, hypertension, peripheral vascular disease, and was on clopidogrel treatment. Due to his existing comorbidities, regional anesthesia was considered the right method. The combination of femoral and sciatic nerve block was successfully used for the operation, which lasted for one hour and fifty minutes under sedation, and was continuously supplied with a propofol infusion. The patient was safely discharged to the surgical ward with no pain. The femoral block and sciatic block combination is described as one of the most useful, and at the same time, the most ignored anesthetic method. This technique is considered a standard technique and is often taught early in training; however, its use seems to be underestimated as there are only a few cases documented in Turkey. The aim of this case is to serve as a reminder of its significant value in patients who are not appropriate for general anesthesia and neuraxial blocks., Competing Interests: The authors have declared that no competing interests exist.
