Randomized Controlled Trial
Long-term Efficacy of Pectoserratus Plane Block for Prevention of Post-mastectomy Pain Syndrome: Extended Follow-up From a Randomised Controlled Trial.
Pectoserratus plane block (PSPB) leads to lower postoperative pain intensity. We examined whether PSPB could also reduce the incidence of post-mastectomy pain syndrome (PMPS) in women undergoing breast cancer surgery. ⋯ The results suggest that, in the long term, PSPB-treated participants were associated with a statistically significantly lower risk of PMPS than those who received standard general anesthesia.

ReviewPerfusion index for early identification of regional anesthesia effectiveness: a narrative review.
Regional anesthesia (RA) is a common and irreplaceable technique in clinical, which can be used in different surgery sites and control of acute and chronic pain, especially for outpatients, pediatrics and the elderly. RA demands are increasing during COVID-19 pandemic because many surgeries could be performed under RA to reduce the risk of cross-infection between patients and health care workers. Early and accurate identification of the effects of RA can help physicians make timely decisions about whether to supplement analgesics or switch to general anesthesia, which will save time and improve patient satisfaction in a busy operating room. ⋯ Recently, many studies have assessed the accuracy of PI in early prediction of RA success, including brachial plexus block, sciatic nerve block, neuraxial anesthesia, paravertebral block, caudal block and stellate ganglion block. Successful RA often parallels increased PI. In this narrative review, we describe the principles and influencing factors of PI, and introduce the effects of PI on early identification of RA effectiveness.

Meta Analysis
General anesthesia or conscious sedation for thrombectomy in stroke patients: an updated systematic review and meta-analysis.
Endovascular treatment for stroke patients usually requires anesthesia care, with no current consensus on the best anesthetic management strategy. Several randomized controlled trials and meta-analyses have attempted to address this. In 2022, additional evidence from three new trials was published: the GASS trial, the CANVAS II trial, and preliminary results from the AMETIS trial, prompting the execution of this updated systematic review and meta-analysis. The primary objective of this study was to evaluate the effects of general anesthesia and conscious sedation on functional outcomes measured with the modified Rankin scale (mRS) at three months. ⋯ In this updated systematic review and meta-analysis, the choice of anesthetic strategy for endovascular treatment of stroke patients did not significantly impact functional outcome as measured with the mRS at three months. Patients managed with general anesthesia may have more frequent successful reperfusion.

Observational StudyProspective analysis on carotid endarterectomy: intermediate-deep ultrasound-guided cervical blockade versus general anesthesia.
The best regional anesthesia plan with the best clinical results for Carotid endarterectomy (CEA) has not been defined yet. ⋯ Although the use of intermediate-deep cervical plexus blockade for CEA confers similar neurologic stability as GA does, there is a difference on the hemodynamic behaviour due to the differences in vasoactive drug consumption. Loco-regional techniques provide a better postoperative pain control and shorten in-hospital length of stay.

Observational StudyEnergy Expenditure Under General Anesthesia: An Observational Study Using Indirect Calorimetry in Patients Having Noncardiac Surgery.
Perioperative hemodynamic management aims to optimize organ perfusion pressure and blood flow-assuming this ensures that oxygen delivery meets cellular metabolic needs. Cellular metabolic needs are reflected by energy expenditure. A better understanding of energy expenditure under general anesthesia could help tailor perioperative hemodynamic management to actual demands. We thus sought to assess energy expenditure under general anesthesia. Our primary hypothesis was that energy expenditure under general anesthesia is lower than preoperative awake resting energy expenditure. ⋯ Median energy expenditure under general anesthesia is about one-quarter lower than preoperative awake resting energy expenditure in patients having noncardiac surgery.
