Conditions
Outcome Measures
Primary Outcomes (1)
The degree of pain at rest ;
using an Visual analogue scale (VAS) scores for pain intensity reported on 0-10 point scale for analysis. (0 = no pain and 10 = the worst possible pain) .
From 2 hours to 24 hours postoperatively
Secondary Outcomes (1)
The time to the first postoperative opioid dose
at 2, 4, 6, and 12 hours.
Other Outcomes (1)
The degree of pain on movement (hip flexion and coughing)
From 2 hours to 24 hours postoperatively
Study Arms (3)
In the TAP group (Group A )
ACTIVE COMPARATORafter completion of surgery, bilateral ultrasound-guided TAP block was performed . Description of the intervention: a 12-4-MHz linear array transducer (ClearVue 350; Philips, Bothell, WA) placed transversely between the iliac crest and costal margin in the anterior axillary line and slid medial-lateral to visualize the external oblique, internal oblique, and trans-versus abdominis muscles; the most lateral (posterior) position obtaining a satisfactory ultrasound image was used ;A 22-gauge spinal needle was introduced from medial to lateral in-plane to the ultrasound probe, and 20 mL of bupivacaine 0.25% was injected under visualization in the plane between the transversus abdominis muscle and the fascia deep to the internal oblique muscle on each side.
In the infiltration group (Group B )
ACTIVE COMPARATORat the end of surgery, 40 mL of bupivacaine 0.25% was injected subcutaneously in the surgical wound (20 mL in each of the upper and lower sides) by the obstetrician before skin closure.
In placebo group (Group C )
PLACEBO COMPARATORroutine analgesic was administered and recorded .
