- Original description
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.Read full original descriptionShow less
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.
Inclusion: Aged 18 years or older; Undergoing elective upper-extremity surgery; Planned for ultrasound-guided brachial plexus block with 0.375% ropivacaine; Able to cooperate with pain assessment and follow-up within 48 hours after block; Written informed consent obtained.
Exclusion: Chronic regular use of opioids before surgery; Allergy or contraindication to amide-type local anesthetics; Coagulopathy or infection at the block puncture site; Pre-existing peripheral neuropathy of the affected upper limb; Cognitive dysfunction unable to complete NRS pain evaluation; Pregnancy or lactation; Incomplete clinical data expected during follow-up.
