Brief summary

The aim of this study is to evaluate analgesic effect of ultrasound-guided retrolaminar block vs ultrasound-guided thoracic epidural analgesia in pain control following laparoscopic cholecystectomy.

Detailed description

To study the difference between the effects of ultrasound-guided bilateral retrolaminar block and ultrasound-guided thoracic epidural analgesia on pain control following laparoscopic cholecystectomy. To relief pain and improve satisfaction in patients undergoing laparoscopic cholecystectomy at Zagazig university hospitals.

Interventions

PROCEDUREBilateral retrolaminar block

in lateral position and after skin sterilization. The spine is palpated from cervical (C7) downward toT7 and point marked to identify the spinous process. The linear high frequency transducer (6-13 MHz) will be placed parasagittal plane 1 cm lateral to the midline. The needle (18 gauge) is inserted in the plane view of the ultrasound probe to target the T7 and needle is advanced from downward to upward until the needle tip contacted the lamina. After negative aspiration, a 20 ml of bupivacaine 0.25 % plus 5ug/ml adrenaline (1:200000) will be injected. The procedure will be repeated following the same steps on the other side.

PROCEDUREThoracic epidural analgesia

In the lateral position, after skin sterilization, Ultrasound with high frequency linear probe (5-13 MHz). Thoracic intervertebral space (T7-8) will be identified by counting from the C7 to prominent thoracic spine (T7). The probe will be used in parasagittal plane 2 cm from midline. The probe will be directed medially to identify the dura matter at the T7-8 intervertebral space . the needle 18 gauage will be inserted in plane to target T7-8 intervertebral space ., after needle tip reached target space, loss of resistance technique then 20 ml bupivacaine 0.25% plus 5ug/ml adrenaline (1:200000) was injected after aspiration

Design outcomes

Primary

MeasureTime frameDescription
Pain intensity at rest and at cough using Numerical Rating Scales (NRS)30 minutes postoperativemeasured by NRS consisted of a series of numbers represents range of pain intensity (10 means the worst pain and 0 means no pain)

Secondary

MeasureTime frameDescription
Time to first call of rescue analgesiawithin 12 hours postoperativestart from retrolaminar or epidural injection of the drug to the time of first call of naluphine
Total analgesic (Naluphine) consumptionwithin 12 hours postoperativeTotal consumption of rescue analgesia(Naluphine) post operative
The number of participant with complications of the techinque (dural puncture , nerve injury, spinal injection, epidural haematoma, pleural puncture)within 24 hours postoperativeThe numer of participant with complications of the techinque (dural puncture , nerve injury, spinal injection, epidural haematoma, pleural puncture)
Patient satisfaction is recorded at the end of 24 hours postoperative24 hours postoperativeusing 5-point Likert-like verbal rating scale by asking the patient about how he/she evaluated their experience with the analgesic management after the surgery?5=very satisfied, 4=satisfied, 3= neutral, 2= dissatisfied and 1= very dissatisfied.
The number of participant with nausea, vomiting, hypotension and bradycardia.24 hours postoperativethe number of participant with nausea (sensation of being about to vomit), vomiting (the expelling of the food content from the stomach through mouth, it will be treated by 4 mg ondansetron), hypotension (if MAP decreases more than 20% of basal reading it will be treated by 12 mg ephedrine) and bradycardia (if HR less than 50 beats/min it will be treated by 0.5 mg atropine).
