NCT06836635

Brief Summary

Video-assisted thoracoscopic surgery (VATS) is a commonly performed minimally invasive procedure that has lead to lower levels of pain. However, VATS require analgesia that blocks both visceral and somatic nerve fibers for more effective pain control. In this study investigators will compare the analgesic effect of ultrasound guided erector spinae plane block (ESPB) and thoracic paravertebral block (TPVB) after VATS.

Outcome Measures

Primary Outcomes (1)

  • To compare the post-operative morphine consumption in first 24 hours between ESPB and TPVB after VATS

    From injection to 24 hours postoperative

Secondary Outcomes (8)

  • Post-operative pain severity assessed by visual analogue scale (VAS) (every 6 hr for 24 hr at rest and during cough).

    From injection to 24 hours postoperative

  • Time of first request of rescue analgesia (rescue analgesia will be given in case of break through pain VAS ≥ 4 inform of 0.1mg/kg morphine).

    From injection to 24 hours postoperative

  • Incidence of post-operative nausea and vomiting.

    From injection to 24 hours postoperative

  • Incidence of complications (haematoma and pneumothorax).

    From injection to 24 hours postoperative

  • Patient satisfaction during procedure (score 1-4 (1= very dissatisfied, 2= dissatisfied, 3= satisfied, 4= very satisfied)).

    From injection to 24 hours postoperative

  • +3 more secondary outcomes

Study Arms (2)

The ESPB group

EXPERIMENTAL

a high-frequency linear ultrasound probe will be placed in a longitudinal orientation 3 cm from the midline. Once the erector spinae muscle and the transverse processes identified, a 100mm needle (B- Braun Medical Inc., Bethlehem, PA, USA) will be inserted after standard skin disinfection in a caudad-to-cephalad direction using a sterile probe cover until the tip lay in the interfacial plane deep to the erector spinae muscle. After hydrolocalization with normal saline, this plane will be opened. 20 milliliters (mL) of 0.25% bupivacaine will be administered for block performance.

Procedure: ESPB group

The TPVB group

EXPERIMENTAL

A high-frequency linear ultrasound probe will be placed in a vertical orientation 23 cm lateral to the midline. Once the transverse process, internal intercostal membrane and parietal pleura identified, a 100mm needle (B- Braun Medical Inc., Bethlehem, PA, USA) will be inserted after standard skin disinfection laterally to medically Use a sterile probe cover until the tip lay in the thoracic paravertebral space beyond the internal intercostal membrane. After injection with normal saline, to confirm ventral pressing of the parietal pleura, 20 mL of 0.25% bupivacaine will be administered for block performance

Procedure: TPVB group

Interventions

ESPB groupPROCEDURE

The patient will be placed in the lateral position. Block will be performed under complete aseptic precautions using ultrasound machine with high frequency linear probe covered with sterile sheath . The block will be performed at the T5-T6 level of the spine using an in-plane approach. Sensory block of the 5th intercostal space in the midaxillary line will be assessed by unilaterally using cold perception until 30 minutes after nerve block. If sensory blockade did not occur, the patient will be excluded from the study.
