Comparative outcomes of peripheral nerve blocks versus general anesthesia for hip fractures in geriatric Chinese patients.

Background: Geriatric patients undergoing hemiarthroplasty for hip fractures have unacceptably high rates of postoperative complications and mortality. Whether anesthesia type can affect the outcomes has still been inconclusive.

Objectives: We compared general anesthesia (GA) and peripheral nerve blocks (PNBs) on postoperative complications and mortality in elderly patients with femoral neck fractures (FNF) undergoing hemiarthroplasty.

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.
