Plain English Summary

Background and study aims
Peripheral intravenous catheter insertion (putting in a drip) is a near universal procedure for pregnant women admitted to the delivery suite. The catheter is inserted for a variety of reasons including for blood tests, fluids or medicines to be given intravenously or as a precautionary measure in the event of a major haemorrhage. Doctors usually put the drip on the back of the hand or in the lower forearm. We do know which place is better for the drip to be placed in pregnant women at term. We think that inserting a cannula at the back of the hand is easier but it can be more painful to insert and prone to failure.

Who can participate?
Women at term with a singleton viable pregnancy admitted to the delivery suite who have suitable veins at the back of the hand and the lower forearm for cannula insertion and who need to have a drip inserted according to usual clinical practice will be invited to participate

What does the study involve?
If you agree to take part, you will need to sign a consent form. The doctor will then insert the catheter in the back of your hand or in a lower forearm vein (usually at the wrist) according to random allocation (an envelope containing the allocation will be opened to reveal the site). The catheter will be inserted and secured using standard techniques. Blood is usually taken from the catheter for any blood test you need. An infusion may be started if you need this immediately. If not, 5 ml of normal saline is used to flush the catheter to make sure it is correctly placed and is patent. If the allocated insertion is unsuccessful, your doctor is free to make a second attempt anywhere according to his best judgment.

What are the possible benefits and risks of participating?
No specific risk is anticipated. Both sites are commonly used for the insertion of an intravenous drip.

Where is the study run from?
The study is conducted in the Delivery Suite of the University of Malaya Medical Centre, a tertiary referral hospital with full-fledged operating theatres and neonatal intensive care unit.

When is the study starting and how long is it expected to run for?
The trial is scheduled to start 1 May 2013 and is expected to be completed within 12 months.

Who is funding the study?

Scientific title

Peripheral Intravenous Catheterisation in Obstetric Patients: comparing dorsum of the hand vein with lower forearm vein: a randomised controlled trial



Study hypothesis

Peripheral intravenous catheterisation in women at term admitted to the delivery suite is more likely to be successfully accomplished but is more uncomfortable when attempted through a vein at dorsum of the hand compared to a vein at the lower forearm.

Ethics approval

Ethics approval from the University of Malaya Medical Centre Medical Ethics Committee. Approval number 975.12 dated 12 March 2013.

2. Vein at the lower forearm

Intervention type

Drug names

Primary outcome measures

1. Successful insertion (defined as full placement of the catheter into a vein at the allocated site after a single skin prick confirmed with a straightforward 5 ml saline flush)
2. Insertion pain score using a visual numerical scale from 1 to 10 (1 no pain to 10 worst pain imaginable)
3. Catheter malfunction (defined as the need for further catheterisation prior to discharge due to deemed unsatisfactory performance of the per protocol indwelling catheter)

Secondary outcome measures

1. Causes of catheter malfunction (if any)
2. Provider’s insertion difficulty grading
3. Patient satisfaction score with site of catheter placement
4) Patient’s preference catheter placement site (post catheter removal)
5) Insertion site complications (at hospital discharge)
a. Swelling
b. Bruising
c. Tenderness
d. Thrombosed vein
6) Patient perception of pain at insertion site after removal of catheter scored using a visual numerical scale from 1 to 10 (1 no pain to 10 worst pain imaginable)
