Randomized Controlled Trial
Subclavian vein ultrasound-guided fluid management to prevent post-spinal anesthetic hypotension during cesarean delivery: a randomized controlled trial.
Hypotension frequently occurs after spinal anesthesia during cesarean delivery, and fluid loading is recommended for its prevention. We evaluated the efficacy of subclavian vein (SCV) ultrasound (US)-guided volume optimization in preventing hypotension after spinal anesthesia during cesarean delivery. ⋯ The trial was registered with the Chinese Clinical Trial Registry at chictr.org.cn (registration number, ChiCTR2100055050) on December 31, 2021.

Randomized Controlled Trial
Comparison of different volumes spread of erector spinae block in postmastectomy pain syndrome management: a prospective randomized comparative study.
Postmastectomy pain is chronic pain that occurs in females after breast surgeries. In this study, we estimated the vertebral levels reached by two different volumes (20 ml and 30 ml solutions) in the erector spinae block (ESB), as well as assess pain improvement and patient satisfaction in females with postmastectomy pain syndrome. ⋯ The injection of a 30 ml solution of 0.25% bupivacaine with methylprednisolone in erector spinae block (ESB) may result in better analgesia and higher patient satisfaction in individuals with postmastectomy pain syndrome (PMPS) compared to a 20 ml solution.

Randomized Controlled Trial
Effect of intravenous induction with different doses of Esketamine combined with propofol and sufentanil on intraocular pressure among pediatric strabismus surgery: a randomized clinical trial.
It is well-established that maintaining stable intraocular pressure (IOP) within the normal range during ophthalmic surgery is important. Esketamine is a commonly used drug in pediatric general anesthesia due to its good analgesic and sedative effects. However, its application in ophthalmic surgery is limited because it can increase IOP. The effect of esketamine combined with other common anesthetics on IOP has been underinvestigated. This study aimed to investigate the effect of different doses of esketamine combined with propofol and sufentanil on IOP during intravenous induction of general anesthesia for pediatric strabismus surgery. ⋯ Propofol combined with sufentanil significantly decreased IOP during the induction of general anesthesia. Although a dose of 0.5 mg/kg esketamine elevated IOP compared to the low-dose and control groups after induction, the IOP remained lower than baseline. 0.25 mg/kg esketamine combined with propofol and sufentanil had little effect on IOP. Therefore, we advocate that a maximum dose of 0.5 mg/kg esketamine combined with propofol and sufentanil will not elevate IOP compared to baseline in pediatric strabismus surgery.

Randomized Controlled Trial
Comparison of the effects of one-level and bi-level pre-incisional erector spinae plane block on postoperative acute pain in video-assisted thoracoscopic surgery; a prospective, randomized, double-blind trial.
This prospective, randomized, double-blind trial aimed to compare the postoperative analgesic efficacy of One-Level pre-incisional erector spinae plane block (ESPB) and Bi-Level pre-incisional ESPB in patients undergoing video-assisted thoracic surgery (VATS). ⋯ Adequate analgesia was achieved in the early postoperative period in the group treated with Bi-Level ESPB with similar morphine consumption and side effects. This may be an advantage, especially in the early postoperative period when the pain is quite intense.

Randomized Controlled Trial
Optimal dose of neostigmine antagonizing cisatracurium-induced shallow neuromuscular block in elderly patients: a randomized control study.
Residual neuromuscular block after using neuromuscular blocking agents is a common and potentially harmful complication of general anesthesia. Neostigmine is a widely used antagonist, but its optimal dose for elderly patients is unclear. ⋯ Timely use of neostigmine after general anesthesia in elderly patients can significantly shorten time of TOF value reaching 0.9, among which 40 µg/kg dosage may be a more optimized choice.
