Anesthesia via peripheral nerve blocks during total knee replacement has no effect on postoperative inflammation in elderly patients.

Background: We have previously shown that, compared with general anesthesia (GA), the procedure of peripheral nerve blocks (PNB) facilitates faster recovery of elderly patients from total knee replacement (TKR). Here, we investigated whether the faster recovery is associated with decreased perioperative stress and inflammation and decreased incidences of postoperative complications.

Methods: After randomization, 165 patients aged ≥65 years underwent TKR under GA or PNB.

Comparison of ropivacaine plus sufentanil and ropivacaine plus dexmedetomidine for labor epidural analgesia: A randomized controlled trial protocol.

Objective: Effective analgesia during delivery can not only decrease pain, but also have a significant function in ensuring the safety of baby and mother. Sufentanil is generally used opioid with ropivacaine in epidural anesthesia in labor pain management; however it can cause some adverse reaction. Dexmedetomidine is an a2-adrenoceptor agonist with high selectivity.

Incidence of bradycardia in pediatric patients receiving dexmedetomidine anesthesia: a meta-analysis.

Background Dexmedetomidine, an α2-receptor agonist, provides potent sedation, analgesia, and anxiolysis without respiratory depression and is used in a variety of surgical and procedural situations. Aim of the review The aim of this study was to estimate the incidence of bradycardia in pediatric patients who received dexmedetomidine as a sole agent for any procedural, intensive care or surgical sedation. Method Literature was searched in electronic databases and studies were selected by following pre-determined eligibility criteria.

Retrospective comparison of the effects of epidural anesthesia versus peripheral nerve block on postoperative outcomes in elderly Chinese patients with femoral neck fractures.

Background: Geriatric patients with femoral neck fracture (FNF) have unacceptably high rates of postoperative complications and mortality. The purpose of this study was to compare the effects of epidural anesthesia versus peripheral nerve block (PNB) on postoperative outcomes in elderly Chinese patients with FNF.

Methods: This retrospective study explored mortality and postoperative complications in geriatric patients with FNF who underwent epidural anesthesia or PNB at the Chinese People's Liberation Army General Hospital from January 2008 to December 2012.

Peripheral nerve blocks versus general anesthesia for total knee replacement in elderly patients on the postoperative quality of recovery.

Background: Both peripheral nerve blocks with sedation or general anesthesia can be used for total knee replacement surgery.

Objectives: We compared these anesthetic techniques on the postoperative quality of recovery early in elderly patients.

Materials And Methods: In our study, 213 patients who were ≥65 years old and undergoing total knee replacement were randomized to peripheral nerve blocks (PNBs) - lumbar plexus and sciatic - with propofol sedation, or general anesthesia with combined propofol and remifentanil.

[Anesthetic management for neurosurgery using intraoperative magnetic resonance imaging].

Objective: To analyze the anesthetic management for neurosurgery using intraoperative magnetic resonance imaging (iMRI).

Methods: Thirty patients with intracranial tumor received MRI for preoperative safety screening and the operation was performed with general anesthesia and support by MRI-compatible machines. The operative time, frequency and duration of MRI, MRI-related time (from the preparation for MRI to the beginning of the surgery), time delay by MRI, body temperature at the initial iMRI and special issues related to the scanning and perioperative anesthesia were recorded.
