Effect of Intercostal Nerve Block With Ropivacaine Combined With Mecobalamine on Chronic Pain After Thoracic Surgery

1. januar 2020 oppdatert av: Han Yuan, Xuzhou Medical University

Effect of Intercostal Nerve Block With Ropivacaine Combined With Mecobalamine on Chronic Pain After Thoracic Surgery -- a Single-center Randomized, Double-blind Controlled Trial

This project intends to investigate the effects of intercostal nerve block with ropivacaine combined with mecobalamin on chronic post-surgical pain (CPSP) in thoracic postoperative patients. Related clinical characteristics of postoperative chronic pain. The results of the study provide clinicians with a simple and inexpensive new method of preventing CPSP, in order to prevent the occurrence of CPSP and reduce the incidence of CPSP, thereby reducing CPSP to patients and their families, hospitals. And public resources.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: ropivacaine combined with mecobalamine
Intercostal nerve block with 0.5% ropivacaine combined with mecobalamine (0.5mg).
Fremgangsmåte: Intercostal nerve block
In the experimental group, the surgeons used 0.5% ropivacaine combined with mecobalamine (0.5mg) before the operation to perform intercostal nerve block in the operating incision, closed thoracic drainage incision and one intercostal nerve block in each upper and lower costal cavity, and injected 5ml in each intercostal nerve block.In the control group, surgeons used 0.5% ropivacaine alone before the operation to perform intercostal nerve block through the operating incision, closed thoracic drainage incision and one intercostal nerve block in each upper and lower costal cavity. 5ml was injected into each intercostal nerve block.
Aktiv komparator: ropivacaine

Tidsramme
Incidence of chronic pain after chest surgery
Tidsramme: At the 3rd month after surgery
The incidence of chronic pain after chest surgery was measured by NRS(numeric rating scales) at the 3rd month after surgery.For pain evaluation,we used the 11 point numeric rating scale(NRS),where an NRS scores of 0 represented "no pain" and a score of 10 represented "worst pain imaginable".

Tidsramme
The incidence of acute pain after chest surgery
Tidsramme: 24 to 72 hours after surgery
An NRS score was performed 24 to 72 hours after surgery to determine the incidence of acute pain after thoracic surgery.For pain evaluation,we used the 11 point numeric rating scale(NRS),where an NRS scores of 0 represented "no pain" and a score of 10 represented "worst pain imaginable".
24 to 72 hours after surgery
Incidence of postoperative neuropathic pain
Tidsramme: At the 3rd month after surgery
The incidence of neuropathic pain was measured by DN4 scale at the 3rd month after surgery.Douleur Neuropathique 4 (DN4) is a screening questionnaire to help identify neuropathic pain (NP) in clinical practice and research,where a DN4 scores greater than or equal to 4 represented the patients had "postoperative neuropathic pain".
At the 3rd month after surgery
Incidence of other postoperative complications
Tidsramme: At the 3rd month after surgery
Postoperative complications included that pulmonary complications, delirium, intestinal obstruction, pulmonary embolism, acute respiratory failure, acute renal failure, incision infection, cerebrovascular accident and other complications related to surgery.
