Table 3 Compares different studies related to the use of ESPB in open hysterectomy

Kamel et al. [15]

bilateral ultrasound-guided erector spinae plane block versus transversus abdominis plane block

48

20 mL of bupivacaine 0.375% plus 5 ug/mL adrenaline (1:200,000) in each side at the level of T9

bilateral ultrasound-guided esp block provides more potent and longer postoperative analgesia with less morphine consumption than transversus abdominis block after the open total abdominal hysterectomy

Altinpulluk et al. [7]

bilateral ultrasound-guided erector spinae plane block

10

15 ml of 0.25% bupivacaine was injected as LA on each side at the level of T9

Bilateral postoperative ultrasound-guided ESP block can result in a good sensory blockade and visceral analgesia

Prasad and colleagues [16]

Peripheral nerve stimulator guided erector spinae plane block

60

20 mL of 0.375% ropivacaine at the level of T10

the ESPB is effective in improving pain

Hamed and colleagues [6]

bilateral ESPB group and control group

60

20 ml of 0.5% bupivacaine was injected as LA on each side at the level of T9

bilateral ESPB significantly reduced postoperative fentanyl consumption and provided acceptable postoperative analgesia

Shukla and colleagues [17]

bilateral ESPB and Transversus Abdominis Plane Block

30

mixing 20 ml of 0.5% bupivacaine plus 10 ml of 2% lignocaine and 1 ml (50mcg) of fentanyl and 9 ml of normal saline forming total 40 ml of which 20 ml was injected on each side

bilateral ultrasound-guided ESPB causes appropriate analgesia and a reduction in the need for analgesia with less tramadol consumption compared to ultrasound-guided Transversus Abdominis Plane block
