About this study

Official title: Comparison Between Fentanyl And Midazolam As Additives To Bupivacaine In Ultrasound Guided Transversus Abdominis Plane Block in Patients Undergoing Abdominal Surgeries; A Randomized Controlled Study

Pain triggers a complex biochemical and physiological stress response leading to impairment of pulmonary, immunological and metabolic functions.

The Transversus Abdominis Plane (TAP) block, is a regional anaesthesia technique used for various surgeries through the lower to mid-abdominal wall.The addition of fentanyl to the local anaesthetic in ultrasound-guided TAP block prolongs the analgesia, lowers postoperative pain, and decreases the opioid consumption. Adding midazolam as a bupivacaine adjuvant for TAP block reduces the 24-h morphine consumption extends the postoperative analgesia duration. The aim of the work is to study the effect of the addition fentanyl and midazolam on the onset, duration of the analgesic effect of Tap block intraoperative fentanyl consumption, Time for first rescue Analgesia.

in patients undergoing simple unilateral abdominal surgeries.

Read the detailed description

Informed written consent will be obtained from study participants or their legally authorized representative. This is a randomized controlled double blinded study; patients will be enrolled in the study and will be randomized and equally divided into three groups:

Group A: (TAP block with 20 ml of bupivacaine 0.25% and 50 μ g of fentanyl) Group B: (TAP block with 20 ml bupivacaine 0.25% and 50 μ g /kg midazolam) Group C: (TAP block with 20 ml bupivacaine 0.25% only). Induction of general anaesthesia will be performed using a regimen of IV 1 μ g/kg fentanyl and Propofol IV 2 mg /kg. Tracheal intubation will be facilitated using 0.5 mg/kg IV of atracurium.

Maintenance of Anaesthesia:

Anaesthesia will be maintained with inhaled sevoflurane with MAC 2% in oxygen enriched air (FiO2=0.5) and top up doses of Atracurium (0.1 mg/kg) IV will be administered every 30 minutes.

Ringer acetate will be infused to replace their fluid deficit, maintenance and losses, and the patients will be mechanically ventilated using the appropriate setting that will keep the end-tidal CO2 at 30-35mmHg.

One reading of mean arterial pressure (MAP) and heart rate (HR) will be taken 1 minute before induction of general anaesthesia (a baseline reading), 1 minute before surgical incision and at 15-minute intervals intra operatively.

Lack of inadequate intraoperative analgesia, as defined by an increase in pulse rate, sweating, and tearing (PRST) score >2 or an increase of mean arterial blood pressure (MAP) >20% of baseline (8) was treated by additional rescue IV fentanyl 1-2 mcg/kg IV bolus.

Hypotension will be treated with 0.9% normal saline and/or 5mg ephedrine in incremental doses to maintain mean blood pressure above 70 mmHg.

The residual neuromuscular blockade will be reversed using neostigmine (0.05 mg/kg) and atropine (0.02 mg/kg), and extubation will be performed after complete recovery of the airway reflexes.

The patient will be transferred to the post-anaesthesia care unit (PACU) where the MAP and HR will be recorded immediately upon arrival.

Side effects such as local anaesthetic toxicity, postoperative nausea and vomiting (PONV), respiratory depression (respiratory rate <10/minute) will be recorded.

What participants receive

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

  • Ultrasound Guided Transversus Abdominis Plane BlockProcedure or surgery

    The patient will lie in the supine position. The transducer will be placed in the axial plane on the mid-axillary. transversus abdominis muscle will be visualized. A skin wheel using 3 ml of lidocaine 1 % is made 2 to 3 cm medial to the medial aspect of the transducer and the 22 gauge is inserted in-plane pointing laterally. Then Injection of local anaesthetic mixure in the right plane.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Onset of the Analgesic effect of TAP block with different additives

    The patient will be asked to register a prick respectively on the upper extremity. Sensory change will then be assessed in the mid-clavicular line, starting above dermatome T4 moving caudally to dermatome L4.

    Measured: 30 minutes

Secondary outcomes (4)
  1. Dose of intra-Operative fentanyl consumption

    Lack of inadequate intraoperative analgesia, as defined by an increase in pulse rate, sweating, and tearing (PRST) score >2 or an increase of mean arterial blood pressure (MAP) >20% of baseline was treated by additional rescue IV fentanyl 1-2 mcg/kg IV bolus.

    Measured: 2 hours

  2. Block related complications

    haematoma, neurological complications

    Measured: 24 hours

  3. Time of first analgesic request

    visual analogue scale equals or more than 4

    Measured: 24 hours

  4. Incidence of postoperative nausea and vomiting

    will be assessed using by yes/ no scale

    Measured: 24 hours postoperative

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?

Onset of the Analgesic effect of TAP block with different additives (time frame: 30 minutes). 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 NCT04426617, which also lists 3 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.
