What is meant by an episiotomy?

A surgical incision on the perineum made to increase the diameter of the vulval outlet (and likely expedite birth)
The fourchette, perineum and perineal body are involved ( the same as a second degree tear).

What are epicissors-60 used for

Surgical scissors used for episiotomy and a designated to achieve a medico lateral cut at 60 degrees to the perineal midline to minimise the risk of obstetric anal sphincter injuries.

What is the midwife role to assessing tear?

Following the 3rd stage of labour
Assessment of perineum-skin/muscle
Assessment of vaginal wall
Assessment of the anal sphincter

Equipment needed for perineal repair

Sterile gloves
Swabs
Water (and receptacle)
Analgesia?
Inco sheet
Light
Lubricant? (For anal examination)
Lithotony?

What is the aim of perineal repair?

Haemostatisis
Minimise bleeding
Reduce risk of infection
Assist healing through primary intention and correct anatomical alignment
Maintaining overall integrity of the pelvic floor.

How do you prepare the woman for perineal repair?

Clear explanation and rationale of plan and procedures
Test and confirm analgesia is sufficient before proceeding
Position the woman so she is comfortable
Clear visual access to identify extent of trauma and structures involved
Identifying the apex and bleeding vessels
Rectal examination to exclude damage to the external and internal anal sphincter
Explanation of findings and procedures undertaken.

What are the basic surgical skills needed for perineal repair?

Types of surgical instruments
Handling of instruments
Positioning and guarding the needle
Surgeons square knot
Insertion of continuous subcutaneous sutures
The Aberdeen knot.

Instruments needed for repair?

Needle holder
Dissecting forceps
Scissors
Suture material

What are the basic principles for handling surgical instruments?

Safety
Economy of movement
Relaxed handling
Avoid awkward movement.

What should the position of the needle be?

Last 1/3 of the needle (the part closest to thread)
At the right angle to the curve of the needle
Grasp the needle securely
Backhand or forehand position to the left or right of the holder

What is meant by the guarding of the needle and how is this done?

Rotate teh needle backwards
Length and tip of the needle lie towards the centre of the needle holder
Ensure sharp tip is protected.

What is the first stage of the surgeons square knot?

• Instruments Positioned in the 'V' shape of the suture material • Wrap the left hand twice around the forceps in clockwise dirction • Short end of material on the right-hand side with the forceps • Pull it tight, crossing the hands • Make sure it lies flat

What is the second stage of the surgeons square knot?

• Keep the Instrument in the 'V' shape of the suture material • Reverse the direction of the suture material • Wrap the right-hand once around the forceps in anti-clockwise direction • Short end of the material on the left-hand side with the forceps • Pull it tight

What is the third stage of the surgeons square knot?

Keep within the V shape Change the direction of the suture material around the forceps clockwise Position if the hands Pull it tight Short end of material is cut for and anchor knot. Or both ends if it’s in for a single interrupted stitch.

How to you perform an insertion of continuous subcutaneous sutures?

-Start at the lower end of the wound to the enteroitus * Each new stitch should enter directly opposite the exit of the previous stitch * If not, this may cause 'puckering' or unevenness of the final wound closure * Use dissecting forceps to the skin edge and gently retract the skin to facilitate visualisation of the subcutaneous tissue * Take bites of subcutaneous tissue with the needle exiting under the skin edge * Your movement should follow the curve of the needle * Draw tightly together

What is the first stage of the Aberdeen knot?

* Hymenal remnant emerge on lefthand side of the wound * Then Insert on the right side of wound exiting on left side * Leave a small loop

What is the second stage of the Aberdeen knot?

*Pull the suture material through in a see saw manor * Pulling on the lower thread to close the loop * Leave a small loop * Repeat three times * Ensure the third knot is placed flat on the tissue

What is the third stage of the Aberdeen knot?

* Needle can be pulled through the loop * Guard the needle * Pull the suture material tight * Cut the end 0.5cm to1cm away from the knot.

What are the steps to the continuous technique?

*Examining the perineum * Infiltrating the local anaesthetic * Using the correct suturing material * Surgeons square knot * Repair of Vaginal Trauma * Re-approximating the perineal muscles * Skin Closure * Securing the repair – Aberdeen knot.

what should we do for postnatal perineal care?

Postnatal perineal examination Postnatal advice Documentation

What are the points when giving post-surgical advice?

Care and hygiene Diet and Hydration Pelvic floor exercises Analgesia Sexual Intercourse

What needs documenting after perineal repair?

* Documentation of consent (NMC, 2015) * Description or pictorial diagram of tear * Analgesia used * Method technique of suturing * Materials used * Correct count of needle and swabs * Per rectum (PR) and Per vagina (PV) examination * Estimated blood loss (EBL) * Name and designation of midwife undertaking the repair

What is important post examination to do?

Counting swabs After care information Debrief Documentation/Datix
