Comparing Subsartorial Saphenous Nerve Blocks With and Without Dexamethasone for Anterior Cruciate Ligament Reconstruction
Postoperative Analgesia Comparing Subsartorial Saphenous Nerve Block With and Without Dexamethasone in ACL Reconstruction
For patients undergoing Anterior Cruciate Ligament reconstruction surgery, the postoperative period can be a painful experience without adequate pain management. Hence the investigators propose a randomized controlled clinical study, investigating prolonged saphenous nerve blocks. Patients will be randomized to receive saphenous nerve blocks with or without dexamethasone, a corticosteroid used to prolong analgesia.
Depending on the randomized treatment assignment, patients may receive one of the following:
- 13 ml of 0.5% bupivacaine, a local anesthetic (no dexamethasone);
- 13 ml of 0.5% bupivacaine mixed with 1 mg of dexamethasone;
- 13 ml of 0.5% bupivacaine mixed with 4 mg of dexamethasone.
Patients will be followed postoperatively. Following admission to the recovery room, data collectors will ask patients to rate their pain on a scale of 0-10 until discharge. Data collectors will also record patient satisfaction, pain medication use and any side effects experienced (i.e. nausea and vomiting). Patients will then be contacted on postoperative days 1, 2 and 14 and asked questions about their general well-being.

Deelnemersgroep / Arm |
Interventie / Behandeling |
|---|---|
|
Placebo-vergelijker: Controle
|
This is the control treatment arm.
Patients will receive an ultrasound-guided saphenous nerve block, consisting of 13 ml of 0.5% bupivacaine (a local anesthetic).
|
|
Actieve vergelijker: Dexamethasone 1 mg
|
This is one of two treatment arms.
Patients will receive an ultrasound-guided saphenous nerve block, consisting of 13 ml of 0.5% bupivacaine (a local anesthetic), mixed with 1 mg of dexamethasone.
Total injection volume will be 15 ml.
|
|
Actieve vergelijker: Dexamethasone 4 mg
|
This is one of two treatment arms.
Patients will receive an ultrasound-guided saphenous nerve block, consisting of 13 ml of 0.5% bupivacaine (a local anesthetic), mixed with 4 mg of dexamethasone.
Total injection volume will be 15 ml.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Patient-perceived Duration of Analgesia
Tijdsspanne: Up to 2 days following surgery
|
After discharge, patients will be called and given instructions to help determine length of time of analgesia in the saphenous nerve distribution.
|
Up to 2 days following surgery
|
Secundaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
NRS (Numerical Rating Scale) Pain Scores
Tijdsspanne: Postoperative day 1
|
Patients will be asked to rate, on a scale of 0-10, their pain while at rest.
0 indicates no pain, and 10 indicates the worst pain imaginable.
|
Postoperative day 1
|
|
Patient Satisfaction
Tijdsspanne: Up to 2 days following surgery
|
Patients will be asked to rate satisfaction on a scale of 0-10 (0=completely dissatisfied, 10=completely satisfied);
|
Up to 2 days following surgery
|
|
Postoperative Morphine Consumption
Tijdsspanne: Up to 2 days following surgery
|
Data collector will record how many opioids (i.e.
Percocet, Vicodin) the patient has used since discharge.
|
Up to 2 days following surgery
|
|
Opioid-Related Side Effects (Drowsiness)
Tijdsspanne: Up to 2 days following surgery
|
Data collector will administer the Opioid-Related Distress Scale (OR-SDS) to determine if patients experience any opioid-related side effects (i.e.
drowsiness).
The OR-SDS score is on a scale of 0 to 4, with a higher number representing more severe symptoms.
|
Up to 2 days following surgery
