Clinical Trial Summary
Volunteers are invited to undergo 4 insertions of a peripheral intra-venous 18-gauge catheter
(PIVC); 2 insertions at the the start of the study on the plantar side of the hand/vessel at
the dorsum manus, 2 insertions after 2-10 hours into the forearm/cubita with and without
application of a 10-% lidocaine spray (5 hubs of xylocaine 10%-pump spray; AstraZeneca BV,
Zoetermeer, The Netherlands) prior to the insertion of the PIVC.
Description:
Visit schedule:
Visit 1 Screening: Informed consent, Inclusion and exclusion criteria, Medical history, urine
pregnancy test
Visit 2 Treatment Day1: PIVC vessel dorsum manus+ PIVC forearm/cubita
Treatment Day 1:
First, volunteers will undergo insertion of PIVC into the vessel at the dorsum manus;
Volunteers are randomized in 4 groups, volunteers serve as there own controls
2-10 hours later: All volunteers will undergo insertion of PIVC into the forearm/cubita,
volunteers serve as their own controls.
Clinical investigation procedures:
Lidocaine spray 10 % and the placebo, physiological saline solution, are filled in neutral
brown glas bottles with a dispenser dispensing 0.1ml per pulse of the dispenser by the
Pharmacy of the Konventhospital Bermherzige Brüder Linz, The operator and the volunteers are
unaware which bottle contains the 10% lidocaine and which bottle the saline solution. 5
pulses of either lidocaine 10% or saline are applied to the site of the planned venipuncture
(plantar side of the hand/vessel at the dorsum manus), an hourglass indicating the 2 min time
is turned. The tourniquet is then loosened. After 2 minutes the tourniquet is tightened
agained, desinfection is performed, another 30 sec is waited-timed by an hourglass-and the
insertion of the PIVC is performed. The following PIVC will be used: BD Venflon Pro Safety,
BD Vialon Material; 18G 1.3 x 32 mm; (Beckton Dickinson Therapy, Helsingborg, Sweden). To
check for success of the insertion of the PIVC 5 ml of saline is injected; either way
(success/failure) the PIVC is to be removed and the pain caused by PIVC rated by NRS is
recorded. A pressure bandage will be applied and the volunteer is checked for well being and
discharged at the principal investigator's discretion. Then the same procedure is repeated on
the other extremity.
Description of Randomization:
4 randomization groups are defined per protocol. "Dominant" refers to the stronger
hand/forearm.
- Group A: dominant/Placebo - non-dominant/LA
- Group B: non-dominant/Placebo - dominant/LA
- Group C: non-dominant/LA - dominant/Placebo
- Group D: dominant/LA - non-dominant/Placebo
On the treatment day the subinvestigator will obtain a card for each subject in which the
treatment for each subject is specified. There are 40 cards and each card specifies the
treatment protocol for a single subject. See attached document 2023-507859-29 Randimization
cards.
Randomization is performed by a standard randomization program; groups are stratified by
where (dominant vs. non-dominant extremity) the first PIVC will be inserted and whether LA or
placebo is used at the first PIVC insertion resulting in 4 distinct groups.
No effect of order of dominant/non-dominant and placebo/LA is expected and thus in the main
statistical analysis (see above) the randomization will not be taken into account.
Nevertheless, an additional statistical analysis will be run as sensitivity analysis where
the both randomization factors will be used as control variables in an ANOVA model.
Neither the subinvestigator nor the subjects will know what the content of the bottles are.
The plantar side of the hand and the forearm/cubita are randomized separately into the four
groups A,B,C,D. Afterwards hand and arm are combined with each other.
Two separate block randomizations are forseen for the plantar side of the hand/vessel at the
dorsum manus and for forearm/cubita via Software R version 4.2.2
Medication:
Lidocaine spray 10 % (Xylocaine 10% pump spray; AstraZeneca BV, Zoetermeer, The Netherlands)
and the placebo, physiological saline solution (NaCl 0,9% 250ml Fresenius KABI), are filled
in neutral brown glass bottles with a dispenser dispensing 0.1ml per pulse of the dispenser
by the Pharmacy of the Konventhospital Barmherzige Brüder Linz on the basis of AMG.
Lidocaine spray 10 % (Xylocaine 10% pump spray) and the placebo (physiological saline
solution NaCl 0,9%), are filled in neutral brown glass bottles. Four bottles (a,b,c,d) are
prepared by the pharmacy. 2 bottles each are available. 2 bottles with label "a" and "b" for
plantar side of hand/vessel at the dorsum manus and 2 bottles with label "c" and "d" for
forearm/cubita. One of the bottles "a" and "b" is a placebo and the other one the local
anaesthetic. One of the bottles "c" and "d" is a placebo and the other one the local
anaesthetic.
The content of these bottles are only known by the Sponsor and the pharmacy.
The person responsible for PIVC insertion and the volunteers are unaware which bottle
contains the 10% lidocaine and which bottle the saline solution. Due to the banana like smell
of lidocaine the person responsible for PIVC insertion and the volunteer will wear nose clips
during the procedure.
Null hypothesis:
There is no difference in pain with and without application of LA for the plantar side of the
hand/vessel at the dorsum manus, and the forearm/cubita.
Alternative hypothesis:
There is a difference in pain with and without application of LA for the plantar side of the
hand/vessel at the dorsum manus, and the forearm/cubita.
Primary objective:
• To demonstrate a reduction of pain caused by PIVC rated by Numerical Rating Scale (NRS),
after application of a 10% lidocaine spray- Separately measured for the plantar side of the
hand/vessel at the dorsum manus, and for the forearm/cubita.
Secondary objectives:
- To measure pain caused by PIVC rated by NRS in the dominant vs. non-dominant arm
- To measure pain caused by PIVC rated by NRS at the plantar side of the hand/vessel at
the dorsum manus, vs. at the forearm/cubita
- To measure the correlation between pain caused by PIVC rated by NRS and the anticipated
pain rated by NRS
- To measure the correlation between pain caused by PIVC rated by NRS and the anticipated
difficulty by the operator to insert the PIVC
- To measure pain rated by NRS depending on success
- To describe success rates and compare it
- To measure the correlation between PCS and pain caused by PIVC rated by NRS
Statistics Pain caused by PIVC rated by NRS with/without application of local anesthesia will
be analyzed by a paired- t-test. NRS is used as a continuous measure and we expect the values
to be approximately normally distributed and therefore plan a parametric test. Normal
distribution will be investigated via Q-Q-plots. If there is no normal distribution, the
non-parametric Wilcoxon test for paired samples will be used instead of the paired t-test.
For descriptive analyses, mean values and standard deviations will be reported. For each
primary outcome (plantar side of the hand/vessel at the dorsum manus and the forearm)
separate significance tests for separate null hypotheses will be calculated and no adaption
of the error due to multiple testing is needed. The analysis will be performed with the SPSS
software (SPSS 32.0, SPSS Inc., Chicago, IL).
For the analysis of the secondary endpoints paired t-test, independent t-tests and pearson
correlation will be used. If the data is not normal distributed, wilcoxon test for paired
samples, Mann-Whitney-U test for independent samples and spearman correlation will be
employed instead. For analyzing the success rate a chi-squared test will be calculated for
comparison of groups.
