- University Tunis El Manar
- Brief Summary
Pain following open reduction of mandibular fractures is the most reported complaint during the first 24 post-operative hours. The goal of this clinical trial is to evaluate the impact of inferior alveolar nerve block with bupivacaine 0,5% in patients with mandibular fractures.
The main question it aims to answer are:
* Does the inferior alveolar nerve block with bupivacaine reduce the intensity of pain after mandibular fracture surgery?
* Does the inferior alveolar nerve block with bupivacaine decrease the consumption of analgesics during the first 24 postoperative hours?
Participants with bifocal mandibular fractures will be enrolled in the study (a fracture should be located on the dentate portion of the right hemi-mandible, and a second fracture located on the dentate portion of the left hemi-mandible). Each patient will receive either a right or left inferior alveolar nerve block.
The patient:
* Will be asked to estimate the pain score by the numerical rating scale during the first 24 postoperative hours for each fracture.
* They will be given rescue analgesia in case of intense pain. The number of uses of rescue analgesia will be noted.
Researchers will compare a group of fracture that will receive the inferior alveolar nerve block with bupivacaine with a group of fracture that will not receive the inferior alveolar nerve block, to see if regional anesthesia improve postoperative pain management of mandibular fractures.

- Arm && Interventions
Group Intervention Description Group BNAI+ Bupivacain Randomization process will be used to preoperatively assign patient's left or right side to receive inferior alveolar nerve block. At the end of the surgery, each patient will receive an inferior alveolar nerve block with 2ml of bupivacaine 0.5% on one side ;the other side will not be injected. This arm include the group of fracture which will receive an inferior alveolar nerve block with bupivacaine. All patient will receive during the postoperative period 1 gram of paracetamol each 8 hours.
- Primary Outcome Measures
Name Time Method Post-operative pain 8 hours post-operatively questionnaire with a numerical scale (0 - 10)
- Secondary Outcome Measures
Name Time Method Post-operative pain 2, 4 , 12, 24 hours post-operatively questionnaire with a numerical scale (0 - 10)
Adverse effects 24 hours post-operatively questionnaire including the presence or absence of any abnormal sensations, change in taste, nausea, constipation, fever, diaphoresis, vomiting, light-headedness, palpitations, or headache. The notice of an hematoma or in infection at the site of the injection
The number of instances of rescue analgesia 24 hours post-operatively We will record the number of instances of rescue analgesia following the description of intense pain for each hemi-mandible group.
