Incidence and Clinical Features of Breakthrough Pain After Brachial Plexus Block in Diabetic Patients
An Observational Study on Incidence and Clinical Characteristics of Breakthrough Pain Following Brachial Plexus Block in Adult Patients With Diabetes Mellitus
This observational study aims to determine the incidence and clinical characteristics of rebound-breakthrough pain after ultrasound-guided brachial plexus block in adult patients with type 2 diabetes mellitus. Adult patients undergoing elective upper-extremity surgery are divided into a type 2 diabetes group and a non-diabetic control group. Baseline clinical data and pain-related outcomes are collected after nerve block. This work may provide evidence for optimizing perioperative pain management for diabetic patients receiving brachial plexus block.

詳細な説明
Background: Diabetes mellitus is a highly prevalent chronic disease worldwide. Diabetic peripheral neuropathy is one of its common complications, which may alter peripheral nerve function and pain perception. Brachial plexus block is widely used for upper-limb surgery. Rebound-breakthrough pain is a clinically important adverse event after peripheral nerve block, which worsens postoperative recovery and increases opioid consumption. The incidence and clinical features of this pain among patients with type 2 diabetes remain unclear.
This observational study enrolls adult patients undergoing elective upper-extremity surgery with ultrasound-guided brachial plexus block. Participants are separated into two groups: patients with type 2 diabetes mellitus and patients without diabetes. All patients receive routine clinical anesthesia with 0.375% ropivacaine for brachial plexus block without any experimental intervention. Pre-operative baseline information includes demographic data, glycosylated hemoglobin, diabetic history, and sensory threshold measurement. Post-block data including pain scores, onset and recovery time of sensory-motor block, patient-controlled analgesia usage and additional analgesic consumption are recorded.
The primary objective is to calculate the incidence of postoperative breakthrough-rebound pain. Secondary objectives cover pain severity, onset and duration of breakthrough pain, and perioperative analgesic consumption. Collected data will be summarized and analyzed to describe clinical characteristics associated with breakthrough pain.

Incidence of postoperative rebound-breakthrough pain
時間枠:Within 48 hours after brachial plexus block
|
Proportion of participants developing rebound-breakthrough pain within 48 hours after brachial plexus block.Rebound-breakthrough pain after peripheral nerve block is characterized by sudden severe pain (NRS ≥ 7) occurring within 24 hours after block resolution. It is typically burning in nature, may occur at rest or during movement, lasts more than 2 hours, and most frequently develops 12-24 hours postoperatively. |
