Abstract

Background: Based on the gate control theory of pain,
pain sensation could be prevented or ameliorated,
providing “non-painful input” mitigates “painful input” at the
spinal cord level before reaching the brain level. We aim
to study the efficacy of cryopatch in acute pain control
before local infiltration during spinal anesthesia.
Methods: 70 patients undergoing elective cesarean
section were enrolled at Buriram hospital and
randomized to 2 groups. The study group received
cryopatch (35 patients) and thecontrol group received
room-temperature gel pad (35 patients) both of which
applied to the skin before local infiltration. Pain score,
satisfaction score, blood pressure, and heart rate were
measured before and after spinal anesthesia.
Results: Mean pain score is reduced significantly with
cryopatch use group compared to the control (5.68 VS
3.14, p-value: <0.001) as well as satisfaction score of the
patients (9.11 VS 7.8, p-value: <0.001). The change of the
heart rate before and after spinal needle insertion in study
group was not significantly different (95.82 VS 91.51,
p-value: 0.117) but significantly different in control group
(96.65 VS 105.82, p-value: <0.001). However, there is
significant difference in the change of blood pressure in
study group (89.37 VS 87.94 mmHg, p-value: 0.492) and
control group (89.14 VS 91.80, p-value: 0.090).
Conclusion: Cryopatchfollowed by local infiltration is
effective in acute pain control during spinal anesthesia.Additional study to evaluate the short-term complication
and cost-effectiveness is warrant.
