About

The aim of this study is to compare between Thoracic Epidural Analgesia (TEA) with ultrasound-guided bilateral erector spinae plane (ESP) block in radical cystectomy surgery for analgesic efficacy and hemodynamic effects

Full description

The patients will be randomly allocated into two equal groups using a computer program.

Group A: will receive bilateral Erector Spinae Block after induction of anesthesia.

Group B: will receive Thoracic Epidural Block before induction of anesthesia.

The methods:

Preoperative evaluation of each patient will include full history taking, revision of all laboratory investigations and full clinical examination.

On arrival to the operation room, a standard monitoring will be connected to the patient

In group A, after induction of anesthesia bilateral Ultrasound ESP block will be performed in the left lateral decubitus position under strict aseptic precautions. linear ultrasound transducer will be placed in a sterile cover, and positioned on the midline to identify the T10 spinous process. From this position, the ultrasound transducer will be moved 2-3 cm laterally to visualise the hyperechoic line of the T10 transverse process with its associated acoustic shadow inferiorly, and the overlying erector spinae muscle superiorly. transverse using in-plane approach a needle will be inserted in caudal-cephalad direction, until the tip is contact with the T10 transverse process and will be in the interfacial plane deep to the erector spinae muscle group. A dose of 30 ml 0.125% Bupivacaine will be injected.

In group B, before induction of anesthesia under strict aseptic precautions, 18Gauge Tuohy's needle with Huber's tip will be inserted via median approach after local infiltration with 5 ml of 2% lignocaine at the level of T9-T10 or T10-T11 intervertebral space in the sitting position. After identifying epidural space using loss of resistance technique, 5 ml of saline will be administered after negative aspiration for blood or cerebrospinal fluid and 20Gauge epidural catheter will be threaded 5 cm cranially.then will be administered a bolus dose of 10 ml of 0.125% bupivacaine through epidural catheter followed by continuous infusion of 0.125% bupivacaine at the rate of 0.1 ml/kg/hour . Patients in either group with inadequate analgesia will be excluded from the study.

General anesthesia induction will be achieved using fentanyl 1µg/kg (IV), propofol 2mg/kg (IV), and0.5mg/kg of IV Atracurium. General anesthesia will be maintained with mechanical ventilation with isoflurane (MAC 0.8: 1.2) with O2 \ Air mixture.

During anesthesia maintenance Intraoperatively, if BP or heart rate (HR) increase more than 20% from baseline, intravenous morphine will be given to stabilize the patients' haemodynamics.

All patients will receive 1g intravenous paracetamol and 4 grams ondansetron 8mg dexamethasone.

Erector Spinae Block

Active Comparator group

Description:

after induction of anesthesia bilateral US ESP block will be performed in the left lateral decubitus position under strict aseptic precautions. linear ultrasound transducer will be placed in a sterile cover, and positioned on the midline to identify the T10 spinous process. From this position, the ultrasound transducer will be moved 2-3 cm laterally to visualise the hyperechoic line of the T10 transverse process with its associated acoustic shadow inferiorly, and the overlying erector spinae muscle superiorly. Using in-plane approach a needle will be inserted in caudal-cephalad direction, until the tip is contact with the T10 transverse process and will be in the interfacial plane deep to the erector spinae muscle group and A dose of 30 ml 0.125% Bupivacaine will be injected bilateral in this plane . All patients will receive 1g intravenous paracetamol and 4 grams ondansetron 8mg dexamethasone

Treatment:

Procedure: bilateral Erector spine block,A dose of 30 ml 0.125% Bupivacaine will be injected.

Thoracic Epidural Block

Active Comparator group

Description:

before induction of anesthesia under strict aseptic precautions, 18Gauge Tuohy's needle with Huber's tip will be inserted via median approach after local infiltration with 5 ml of 2% lignocaine at the level of T9-T10 or T10-T11 intervertebral space in the sitting position. After identifying epidural space using loss of resistance technique, 5 ml of saline will be administered after negative aspiration for blood or cerebrospinal fluid and 20Gauge epidural catheter will be threaded 5 cm cranially. the patients in group B will be administered with a bolus dose of 10 ml of 0.125% bupivacaine through epidural catheter followed by continuous infusion of 0.125% bupivacaine at the rate of 0.1 ml/kg/hour All patients will receive 1g intravenous paracetamol and 4 grams ondansetron 8mg dexamethasone
