Outcome Measures

Primary Outcomes (1)

  • Percentage of patients gaining ≥ 50% pain reduction at VAS Score from baseline value.

    Compare the analgesic efficacy between ultrasound paraverbral block and serratus block in chronic postmastectomy pain.

    baseline

Study Arms (2)

serratus plane block

ACTIVE COMPARATOR

20 ml of Bupivacine 0.25% +80mg triamcinlone will be injected in serratus plane under ultrasound.

Procedure: serratus plane block by ultra-sound

paravertebral block

ACTIVE COMPARATOR

10 ml of bubivacine 0.25% +80 mg triamcinlone will be injected at T2 level (paravertebral) under ultrasound.

Procedure: paravertebral block by ultra-sound

Interventions

To perform Serratus block, patients will be placed in the lateral decubitus position with the affected side facing up, or in the prone position with the affected side facing the operator . After sterile preparation, a linear ultrasound probe will be utilized to identify the latissimusdorsi and serratus anterior muscles in a sagittal plane. The plane superficial to the serratus anterior muscle and below the latissimusdorsi muscle will be identified. The skin will be topicalized with 1 mL of 1% lidocaine using a 30-gauge needle. Using an in-plane approach, a 25-gauge 1.5-cm needle will be used to inject a total of 20-mL of 0.25% bupivacaine with 80 mg of triamcinlone under direct ultrasound visualization.

serratus plane block

TPVB will be given using high frequency linear US transducer, place the probe parallel to the vertebral spine at T2 level and shifted 2-3 cm laterally to obtain the appropriate visualization. Following the identification of plura, transverse process and paravertebral space, the needle will be inserted in caudocranial direction using in-plane approach. Confirm negative vessel or pleural breach via aspiration then proceed with local anaesthetic 10ml of 0.25% bubivacine and 80mg triamcinlone slowly; the pleura will be seen to be pushed downward.
