Clinical Trial Summary
One way to reduce pain during epidural needle insertion is infiltration of lidocaine using a
needle. However, infiltration of lidocaine using the needle alone is a painful process. Free
needle infiltration of lidocaine can be an alternative to reduce epidural needle insertion
pain. The study of Gozdemir et al. found that 10% lidocaine infiltration without needle was
less painful than 2% lidocaine infiltration with a 27G needle with no significant difference
in analgesia effect during epidural needle insertion. This study aimed to compare
infiltration of lidocaine with and without needle for epidural needle insertion in a
double-blind study, using a Tuohy needle, Comfort-inTM injector, and wider surgical group as
novelty from previous studies.
This study was a double blind randomized controlled trial. Data collection was carried out
consecutively on 84 subjects with 42 subjects in each group of lidocaine infiltration without
needles and lidocaine infiltration with 23G needles. The effectiveness of analgesia was
assessed from three variables like pain with a Numeric Pain Rating Scale (NPRS) of 0 to 10
during lidocaine infiltration, pain with NPRS during epidural needle insertion, and patient
movement during epidural needle insertion.
Description:
Pain control is an important aspect in patient who will undergo a medical procedure. Reducing
pain will not only improves patient satisfaction and comfort, but also provide speedy and
easy medical procedures application. One of the patient's concerns regarding Anesthesia is
pain when needles injected intracutaneously, intramuscularly, intravenously, or
intrathecally. Epidural anesthesia is one of the neuraxial block technique resulting in
sympathetic, sensory, and motor block depending on the dose, concentration, and volume of the
local anesthetic administered. Epidural anesthesia was performed in 118 cases (18%) of the
total 672 anesthesia cases in November 2020 at the National Central General Hospital (RSUPN)
Cipto Mangunkusumo. Tuohy Type is one of epidural needles commonly used in Epidural
anesthesia at Cipto Mangunkusumo General Hospital. This needle's size is large enough so that
it causes pain if local anesthetic is not given prior to insertion. One of the way to
administer local anesthetic prior to epidural needle insertion is by skin infiltration using
a needle.
Ramzi in his research found that the median Visual Analogue Scale (VAS) due to epidural
needle insertion given lidocaine infiltration with a needle is 5 with a range of 0-10.
Mogensen investigated differences in pain expectations and the actual pain experienced by the
patient due to insertion of the Tuohy needle in epidural anesthesia infiltrated with
lidocaine using a needle. The research found that the median Numeric Rating Scale (NRS) for
pain expectations was 5 while the NRS for actual pain experienced by patients was 2 (p value
< 0.0001). Infiltration of local anesthetic with the needle alone is painful. Gozdemir in his
research found that the pain median due to infiltration lidocaine using the needle before
insertion of the epidural needle was 2 with a range of 0 up to 4.
Several alternative methods have been developed to reduce the pain of local anesthetic
infiltration prior to epidural needle insertion, such as: establishing good communication
with the patient during the procedure, replacing local anesthetic agents with chloroprocaine,
adding bicarbonate to make lidocaine pH close to physiological pH, cooling down the skin with
cryoanalgesia, local anesthetic infiltration with a smaller needle (25-30 G needle),
lidocaine patch, and Eutectic Mixtures of Local Aesthetics (EMLA). Some of these alternatives
still perform needle punctures that can produce pain, although to a lesser degree, and 10% of
the population have a needle phobia. Non-invasive alternatives such as EMLA or cryoanalgesia
cannot be a thorough solution due to the depth of analgesia generated. A study stated that
the depth from skin to lumbar epidural cavity in parturient is 2-9 cm with 89% being on the
3.5-7.5 cm intervals. In leaner patients, the depth of the lumbar epidural found at 2-4 cm.
Whereas EMLA only provides analgesia in depth of 2.9-4.5 mm if EMLA is applied for 60-120
minutes and 6 mm if applied for 3-4 hours. While cryoanalgesia such as vapocoolants spray
works as a temporary topical analgesia by cooling the skin thereby reducing the sensitivity
of pain receptors.
Needle usage, the length of time it takes to produce analgesia, transient analgesia results,
and lack of depth of analgesia are the problems to present an alternative to local anesthetic
infiltration that is completely pain free and adequate. A needleless injection technology can
be a solution to these problems. The medicinal liquid is injected by a tool with high speed
and pressure through a smooth hole. This system is expected to make the analgesia condition
can be achieved quickly, painlessly, and avoiding needle phobia
