ABSTRACT
Introduction and Aim: 1: Dexamethasone is steroid which can be used as add on to local anesthetic for
prolonging the duration of action and has been studied in different neuroaxial blocks. We undertake this
study by comparing the efficacy of bupivacaine alone versus bupivacaine plus dexamethasone during the
surgical TAP block during caesarean section; 2: To correlate the advantages, disadvantages and adverse
effects of the drugs during the surgical TAP block.
Methods and Materials: A double blind randomized control study to include 100 women was approved
by the institutional ethics committee. Patients were randomized as Group A: received surgical TAP block
with Bupivacaine alone. Group B: received TAP block with Bupivacaine plus dexamethasone.
Dose of the drug was adjusted with respect to the weight of the patient and surgical TAP block was
administered via trans-peritoneal route. Visual analogue score (VAS) was assessed by a blinded observer.
Time required for rescue analgesia in minutes was measured. The ’Mann-Whitney U test’ was used for
statistical analysis.
Results: The duration of post operative analgesi a was prolonged in group B. Group A Bupivacaine
had post op duration of analgesia (mean± SD 268.80±125.53 minutes), Group B Bupivacaine plus
dexamethasone had post op duration of analgesia (mean± SD 466.8±207.86). There were no reported
complications during the surgical technique or any adverse effects to bupivacaine and dexamethasone
administered for the TAP block.
Conclusion: Surgical TAP block with bupivacaine plus dexamethasone is more effective than with
bupivacaine alone.

1. Introduction
A lower segment caesarean section commonly induces
moderate to severe post operative pain for 48 hours.
1
Adeqate pain relief should be provided to post caesarean
patients.
TAP block is a regional block anesthesia technique that
earmarks the sensory nerve supply of anterior and lateral
abdominal wall and has been proven as an effective method
to reduce postoperative pain and analgesic requirement for
lower abdominal surgeries in various clinical trials.

The TAP block can be performed successfully using
any one of the three techniques: the blind technique,
ultrasound directed technique and the surgical TAP block
by the operating surgeon.
The surgical TAP block technique has the distinct
advantages of maintenance of asepsis, visible and easy
maneuverability of the needle and tactile confirmation of
correct needle placement and no added risks.
Regional bupivacaine alone is short lived.

Adjuvant
may be used to prolong the local analgesia duration.

Dexamethasone due to its anti inflammatory and blocking
effects on neural discharge and nociceptor C fibers
transmission could be used as a local anesthetic adjuvant.
