Observational Study
The effect of preemptive retrolaminar block on lumbar spinal decompression surgery.
Spinal decompression surgery causes severe pain. Retrolaminar block (RLB) is block, which is done by infiltration of local anesthetic to block spinal nerves between the lamina and superior costotransversospinalis muscle. The primary aim of this study is to evaluate the effectiveness of RLB on postoperative analgesia in patients undergoing spinal surgery. Secondary aims are effects on additional anesthetic and analgesic consumption. ⋯ Preemptive RLB may be used to reduce patients' pain in lumbar decompression surgery as well as to be part of a multimodal analgesia and anesthesia regimen to reduce anesthetic and analgesic drug consumption. Trial registration numberClinicalTrials.gov (No. NCT04209907).

Observational StudyMaximum extension and regression rate of cutaneous sensory block obtained with the external oblique intercostal block or the modified thoracoabdominal nerves block through perichondrial approach in patients undergoing laparoscopic cholecystectomy.
Several studies demonstrate that both external oblique ıntercostal block (EOIB) and modified thoracoabdominal nerves block through perichondrial approach (M-TAPA) contribute to analgesia in the anterior abdomen by targeting the thoracoabdominal nerves through distinct pathways. However, the sensory assessment and dermatomal analysis remain poorly understood. ⋯ Bilateral EOIB and M-TAPA produce a comparable sensory cutaneous block in the anterior abdomen, particularly in the umbilical and epigastric regions. Additionally, the midabdominal cutaneous blocked area was greater in patients undergoing M-TAPA, suggesting a more consistent distribution along the anterior cutaneous branches of the thoracoabdominal nerves.

Ultrasound-guided popliteal sciatic nerve block for surgical anesthesia in wound care patients with ongoing anticoagulant/antiaggregant therapy: A single-center, prospective study.
Ultrasound-guided peripheral nerve blocks may be a good alternative in patients under antithrombotic drugs. We evaluated the efficacy of ultrasound-guided popliteal sciatic nerve block in patients undergoing lower extremity wound debridement of whom antithrombotic drugs could not be stopped. We focused on hemorrhagic complications related to sciatic nerve block. ⋯ Mean block onset time was 16.27 ± 5.69 minutes. Mean postoperative analgesia time was 19.5 ± 11.22 hours. Sciatic nerve block under ultrasound guidance using in-plane technique was safe and provided sufficient surgical anesthesia and postoperative analgesia for lower extremity wound debridement surgery in patients on antithrombotic drugs.
