Trial summary

Postoperative pain is an important clinical issue which negatively affects patient's satisfaction, delays discharge and repeated admission after discharge in orthopedic surgery. Peripheral nerve blocks are commonly used for postoperative analgesia as an adjunct to analgesic drugs. Read more about this study

About this study

Postoperative pain is an important clinical issue which negatively affects patient's satisfaction, delays discharge and repeated admission after discharge in orthopedic surgery. Peripheral nerve blocks are commonly used for postoperative analgesia as an adjunct to analgesic drugs. The aim of this study is to evaluate the effect of ankle blocks performed at the end of the surgery on postoperative discharge times, postoperativeanalgesia, patient's satisfaction, additional analgesic requirements, and complications in patients undergoing orthopedic foot surgery.

Read the detailed description

After written informed consent obtained from patients, patients will be randomly assigned to placebo group (Group I) and block group (group II) using sealed envelope method. IV venous catheter will be inserted and saline or Ringer's Lactate solution will be infused to patients for prehydration.0.1-0.5 mg/kg midazolam will be given for premedication. After arriving into OR, the patients will be monitored with ECG, pulse oximetry and noninvasive blood pressure. Anesthesia will be induced using 2-2,5 mg/kg propofol, 1-2 mcg/kg fentanyl, 10 mg-20 mg rocuronium, and a proper size laryngeal mask airway (LMA) will be placed to secure the airway. The lungs will be ventilated with a mixture of 50% air + 50% oxygen. Propofol and remifentanil based total intravenous anesthesia (TIVA) technique will be used for the maintenance of anesthesia. Tenoxicam 20 mg will be used for preemptive analgesia, cefazolin 25 mg/kg for antibiotic prophylaxis, ranitidine 50 mg for gastric protection, and metoclopramide 10 mg for postoperative nausea and vomiting. Acetaminophen 10-15 mg/kg IV will be given for postoperative analgesia at the time of wound closure.

At the end of the operation, an ankle nerve block will be performed in group II patient using a mixture of 2%lidocaine and 10 ml of bupivacaine and the same amount placebo in group I (placebo group) under the guidance of peripheral nerve stimulator. The anesthesia will be discontinued and LMA will be removed. The patients will be transferred from postoperative care unit to the ward after they were eligible for discharge according to modified Aldrete scoring system.

Postoperative analgesia will be evaluated by a study member who is blinded to study groups using visual analog scale (VAS). Acetaminophen 1000 mg p.o. were given at 8 hours intervals and an intravenous patient-controlled analgesia containing 3 mg/ml of tramadol will be used for postoperative pain therapy. Pethidine 0.5 mg/kg IV will be used for rescue analgesic if VAS score is greater than 3.

The motor block will be evaluated using Bromage scale, sensorial block with pin-prick test. The duration of motor and sensorial block, postoperative VAS scores, the time to the first analgesic requirement, total analgesic consumption and vital parameters will be recorded. Patient's satisfaction will be evaluated using 3 point scale between the scores 0 and 2. 0= poor 1= fair 2=satisfied Postoperative discharge times will be recorded.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • general anesthesiaProcedure or surgery

    Also called Laryngeal mask airway

    The patient will be monitored with ECG, pulse oximetry and noninvasive blood pressure. Anesthesia will be induced using 2-2.5 mg/kg propofol, 1-2 mcg/kg fentanyl, 10-20 mg rocuronium and proper size Laryngeal mask airway will be placed securely the airway.

  • ankle blockProcedure or surgery

    ankle nerve block will be performed in group ankle block patients using a mixture of 5 ml of 2% lidocaine and 10 ml of 0.5% bupivacaine and same amount placebo (saline) in groups placebo under the guidance of peripheral nerve stimulator the anesthesia will be discontinued and LMA will be removed. The patients will be transferred from postoperative care unit to the ward after they are eligible for discharge according to modified Aldrete scoring system.

After than an ankle block will be performed in patient group block patients using a mixture of 5 ml of 2% lidocaine and 10 ml of 0.5 bupivacaine the same amount placebo (saline) in group placebo under the guidance of peripheral nerve stimulator then the anesthesia will be disconnected and LMA will be removed. The patients will be transferred from postoperative care unit toward after they are eligible for discharge according to the modified scoring system.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postoperative pain (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03550677, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
