Meta AnalysisImpact of Regional Anesthesia on Subjective Quality of Recovery in Patients Undergoing Thoracic Surgery: A Systematic Review and Meta-Analysis.
Regional anesthesia can be effective for managing pain after thoracic surgery. This study evaluated whether it can also improve patient-reported quality of recovery (QoR) after such surgery. ⋯ The available evidence suggests that regional anesthesia can enhance QoR after video-assisted thoracic surgery. Future studies should confirm and extend these findings.

Bilateral Greater Occipital Nerve Block; Distal Versus Proximal Approach for Postdural Puncture Headache: A Randomized Clinical Trial.
One of the common neuraxial anesthesia complications is postdural puncture headache (PDPH). Greater occipital nerve block (GONB) is a simple and safe maneuver with a faster onset than other treatment modalities. ⋯ Postdural puncture headache, distal, proximal, greater occipital nerve, block, ultrasound, pain-relieving, neuraxial anesthesia.

Comparison between costotransverse foramen block and thoracic paravertebral block for VATS pulmonary resection: A randomized noninferiority trial.
The present study assessed whether costotransverse foramen block (CTFB) is noninferior to thoracic paravertebral block (TPVB) for postoperative analgesia in video-assisted thoracoscopic surgery (VATS) pulmonary resection. ⋯ The analgesic effect of CTFB was noninferior to that of TPVB during 24 h postoperatively in VATS pulmonary resection. Moreover, CTFB may offer potential safety benefits by keeping the tip of the needle far from the pleura and vascular structure.

Focused ultrasound-induced inhibition of peripheral nerve fibers in an animal model of acute pain.
Moderate-to-severe acute pain is prevalent in many healthcare settings and associated with adverse outcomes. Peripheral nerve blockade using traditional needle-based and local anesthetic-based techniques improves pain outcomes for some patient populations but has shortcomings limiting use. These limitations include its invasiveness, potential for local anesthetic systemic toxicity, risk of infection with an indwelling catheter, and relatively short duration of blockade compared with the period of pain after major injuries. Focused ultrasound is capable of inhibiting the peripheral nervous system and has potential as a pain management tool. However, investigations of its effect on peripheral nerve nociceptive fibers in animal models of acute pain are lacking. In an in vivo acute pain model, we investigated focused ultrasound's effects on behavior and peripheral nerve structure. ⋯ Focused ultrasound, using a distinct parameter set, reversibly inhibits A-delta peripheral nerve nociceptive, motor, and non-nociceptive sensory fiber-mediated behaviors, has a prolonged effect on C nociceptive fiber-mediated behavior, and alters nerve structure. Focused ultrasound may have potential as a peripheral nerve blockade technique for acute pain management. However, further investigation is required to determine C fiber inhibition duration and the significance of nerve structural changes.

Acute cholecystitis is a painful inflammatory disease of the gallbladder. The Low Cervical-2 Plane Block is a retrolaminar block that targets the C3, C4, and C5 spinal nerves, which provide sensory innervation to the gallbladder, in order to potentially provide analgesia to patients with pain associated with acute cholecystitis. ⋯ The Low Cervical-2 Plane Block is a potentially effective modality for treating intractable pain from acute cholecystitis. However, further cadaveric injections are needed to confirm the exact extent of spread of anesthetic. Clinical application of the Low Cervical-2 Plane Block in patients with acute cholecystitis is needed to establish the efficacy of this theoretical technique.
