Randomized Controlled Trial
Ultrasound-guided dexmedetomidine combination with modified high fascia iliaca compartment block for arthroscopic knee surgery: what is the optimal dose of dexmedetomidine?
Total knee arthroplasty (TKA) is a common orthopedic procedure for end-stage knee osteoarthritis. Although effective in relieving pain and improving function, postoperative pain is still a common and distressing problem for many patients. This study aims to investigate efficacy of combined administration of dexmedetomidine and modified high fascia iliaca compartment block (H-FICB) in managing acute and chronic pain after TKA, as well as to identify the optimal dosage of dexmedetomidine. ⋯ In comparison to the other two groups, the administration of combined dexmedetomidine and H-FIB resulted in a significant reduction in pain scores, opioid consumption, and side effects. The optimal dosage of dexmedetomidine was determined to be 1 μg/kg, which provided the most favorable pain relief with minimal adverse effects.

Ultrasound-guided external oblique and rectus abdominis plane "EXORA" block for postoperative pain after laparoscopic cholecystectomy: a propensity-matched study.
Various types of plane blocks are used for analgesia in the upper abdomen. The purpose of this study was to evaluate the efficacy of the external oblique and rectus abdominis plane (EXORA) block for antero-lateral upper abdominal analgesia. ⋯ The EXORA block used to provide analgesia after laparoscopic cholecystectomy provides analgesia to the upper abdominal wall. Further data may be obtained from cadaveric studies and other studies.

A 39-year-old woman with juvenile idiopathic arthritis complicated by nonuremic calciphylaxis presented for pain management of bilateral lower extremity wounds requiring frequent dressing changes. Bilateral single-shot femoral nerve blocks using liposomal bupivacaine and 0.25% bupivacaine were performed. ⋯ Repeat, bilateral single-shot femoral nerve blocks with liposomal bupivacaine and 0.25% bupivacaine were performed approximately every 72 hours to maintain adequate analgesia. We conclude that off-label use of liposomal bupivacaine in femoral nerve blocks results in prolonged block duration without adverse effects or tachyphylaxis.

Randomized Controlled TrialPreoperative Ultrasound-Guided Internal Branch Block of Superior Laryngeal Nerve Reduces Postoperative Sore Throat Caused by Double Lumen Endotracheal Intubation: A Randomized Trial.
Postoperative sore throat (POST) is one of the more common side effects of tracheal intubation patients under general anesthesia (GA) after extubation using double-lumen endobronchial tubes (DLTs). The internal branches of the superior laryngeal nerve (SLN) block (iSLNB) have been reported to anesthetize the larynx for airway manipulation (such as awake tracheal intubation) and pain treatment efficiently. We hypothesized that ultrasound-guided iSLNB (US-guided iSLNB) combined with GA would ameliorate the incidence and severity of POST and hoarseness. ⋯ Preoperative US-guided iSLNB could significantly ameliorate the incidence and severity of POST induced by double-lumen bronchial catheter intubation.
