Clinical Trial Summary
A double-blind randomized control study to compare the efficacy of dexmedetomidine versus
ketamine as an adjuvant in combination with bupivacaine ultrasound-guided ESP block in
patients scheduled for cardiothoracic surgeries with thoracotomy incision.
Description:
Following approval from research and ethics committee ,preoperative preparation, and
induction of anesthesia Patients will be allocated to three groups according to the type of
drug injected.
Group bupivacaine(Control) (B) received 0.5 ml/kg bupivacaine 0.25% diluted with isotonic
saline (total volume15 ml).
Group bupivacaine - ketamine (K) received 0.5 ml/kg bupivacaine 0.25% with ketamine 2 mg/kg,
diluted with isotonic saline (total volume15 ml).
Group bupivacaine - Dexametomedine (D) received 0.5 mL/kg bupivacaine 0.25% with
dexmedetomidine 1 µg/kg. diluted with isotonic saline (total volume 15ml).
Unilateral Ultrasound-guided erector spinae block will be applied in both groups after the
induction of anaesthesia. All patients will be tilted onto their left side (lateral
position). while the ultrasound-guide unilateral erector spinae block will be performed under
completely aseptic conditions. The anatomy will be examined by ultrasonography at 5-6Hz with
a35 mm linear probe and a SonoSite M-turbo system (Fujifilm SonoSite, Inc., USA). a 22 g
bevel needle will be advanced in a cephalad to caudad direction until the tip of the needle
reach' the plane deep to the erector spinae muscle and immediately lateral to the transverse
process. Once confirmed, after careful aspiration to demonstrate the absence of air or blood.
An injection in this plane permitted the block to impact both the dorsal and ventral rami as
they exited from the thoracic spine to innervate the chest wall. the block permits a
diminished sensation spanning the T3-T10 dermatome levels. confirming the correct tissue
plane by hydro-dissection.
Heart rate, mean arterial pressure, and oxygen saturation will be monitored continuously.
After completion of the surgery, inhalational anesthetics will be stopped as well the muscle
relaxant. The patient will be then transferred to the ICU.
Postoperative assessment and analgesic regimen:
Post-operative pain intensity will be assessed using the objective pain score (OPS) by a
person who will be blinded to the treatment. OPS score will be recorded at baseline,3,6,12,24
and 48 hours post-operatively to evaluate acute pain will be observed and recorded. for the
score 4 or more, which was considered the end point of the study, and at this point. Patients
will receiv paracetamol 15 gm / Kg IV /6 h, as components of multimodal analgesia regimen for
postoperative pain control.
Persistent or breakthrough pain will be managed with incremental intravenous morphine at a
dose of 0.1mg/kg to maintain resting (OPS) score ˂ 4.
