Overview
Persistent postoperative pain is a substantial pain (scores 4-10 using a 0-10 numeric scale) that develops 3 months after surgery.
Persistent postoperative pain can be a problem even in ambulatory surgery. Loco-regional analgesia could prevent the occurrence of this pathology but contradictory results are found in ancient studies.
This study is the first randomized controlled study in children about loco-regional analgesia and persistent postoperative pain in traumatologic orthopedic surgery.
One interventional arm will receive a locoregional analgesia after general anesthesia and before incision. The other arm will only receive systemic analgesia during general anesthesia.
The incidence of persistent postoperative pain at 3, 6 and 12 months will be compared in these two groups.
The goal is to show the decrease of the incidence of the persistent postoperative pain in the group "locoregional analgesia".
Description
Patients between 5 years old and 15 years, 3 months old operated for a traumatologic orthopedic surgery in CHU Nantes will be included in this study.
Patients between 5 years old and 15 years, 3 months old operated for a traumatologic orthopedic surgery in CHU Nantes will be included in this study.
They will be randomized in two groups. General anesthesia will be administered in both groups.
One arm will receive a locoregional analgesia guiding by echography before incision with a local anesthetic (Carbocaïne) and a systemic analgesia if necessary. One arm will only receive a systemic analgesia.
The drugs used for general anesthesia and systemic analgesia will be standardized in the two groups.
The incidence of persistent postoperative pain at 3, 6 and 12 months will be compared in both arms. A screening of a neuropathic pain will be realized if a pain exists.
The consumption of opioids the first 24 postoperative hours, the time spent in the post interventional care unit and the incidence of nausea, vomiting will also be compared.
The goal is to show the decrease of the incidence of the persistent postoperative pain and a better recovery in the post interventional care unit in the group "locoregional analgesia".
