A Randomized comparative study of ultrasound guided superficial cervical plexus block versus local infiltration for post operative analgesia in modified radical mastoidectomy”

Regional blocks such as Superficial cervical plexus block (SCPB) and Local infiltration are both techniques used in post operative patients undergoing Modified Radical Mastoidectomy(MRM) surgery to reduce postoperative pain.

After getting approval from Institutional Ethical Committee (IEC) ,those patients who are fit in inclusion criteria will be included in our study

Randomization using computer generated random number which are sealed in opaque envelop will be done.

General anaesthesia will be given as per the institution’s protocol.

After surgery before extubation, SCPB and Local infiltration will be perfomed under the gudiance of ultrasound machine (Sonosite MicroMaxx P08840-22)with

5-10Hz linear probe using 5cm echogenic needle

Group S-Ultrasound guided SCPB, 5ml Ropivacaine 0.5%

Group L- Local infiltration, 5ml Ropivacaine 0.5%

The patient will be shifted to PACU and standard analgesia (1 gm PCM 8 hrly i/v) will be given as per standard institute protocol.

VAS score and haemodynamic parameter will be recorded in PACU 0min, 5mins, 10mins , 15mins, 30mins then 1st hr, 4hr , 8hr, then after12hrs, 18hrs, and 24hrs.

VAS >4 will be given rescue analgesia in form of I/V diclofenac 75mg. Total rescue analgesic consumption

in 24 hrs and complications will be noted.

Data will be analyzed using the appropriate statistical method.
