Episiotomy

 Episiotomy 

Definition: The making of an incision into the prenium to enlarge the vaginal orifice.

 

Indications for Episiotmy

 

·                 Delay due to rigid perineum, disproportion between fetus and vaginal orifice.

·                 Fetal distress due to prolapsed cord in second stage.

·                 To facilitate vaginal or intra uterine manipulation Eg. Forceps, breach delivery

·                 Preterm baby in order to avoid intracranial damage

·                 Previous 3rd degree repaired on the perineum.

 

 

Advantages of episiotomy

 

·                 Fetal acidosis and hypoxia are reduced

 

·                 Over stretching of the pelvic floor is lessened

 

·                 Bruising of the urethra is avoided.

 

·                 In sever pre – eclampsia or cardiac disease to reduce the effort bearing down.


·                 A previous third degree tear which may occur again because of the scar tissue which does not stretch well is prevented.

 

Types of Episiotomy

 

·                 Medio- lateral

 

·                 Median

 

·                 J- shaped

 

·                 Lateral

 

 

1.  Medio – lateral

 

The incision is begun in the center of the fourchette and directed posterio laterally, usually to the woman’s right. Not more than 3cm long & directed diagonally in straight line which runs 2.5cm distance from the anus. Advantages - barthlion glands are not affected

 

Anal sphincters are not injured

 

2. Median: The incision begun in the center of thefourchette and directed posteriorly for approximately 2.5cm in the midline of the prenium.

 

Advantage:

 

·                 Less bleeding

 

·                 More easily and successfully repaired

 

·                 Greater subsequent comfort for the women

 

3. J – shaped : The incision is began in the center or thefourchtte and directed posteriorly in the midline for about 2cm and then directed towards 7 on the clock to avoid the anus. Disadvantage

 

-   The suturing is difficult

 

-   Shearing of the tissue occurs

 

-   The repaired wound tends to be pucked.

 

4. Lateral: The incision is begun one or more in distant fromthe condomned.

 

Disadvantages

 

·                 Bartholins duct may be served

 

·                 The levatorani muscle is weakened

 

·                 Bleeding is more profuse

 

·                 Suturing is more difficult

 

·                 The woman experiences subsequent discomfort

 

 

Local analgesia for Episotomy

 

Lignocaine /lidocaine/ 0.5 percent of 10ml is safe and efficient.

 

It takes effect rapidly with in 1 & 2 minutes.

 

 

Timing the incision

 

·                 The head should be well down on the perineum, low enough to keep it stretched and thinned

·                 In breech presentation the posterior buttock would be distending the perineum

·                 It must be made neither too soon nor too late 

 

Making the incision

 

·                 Avoid incision on the previous episiotomy scar

 

·                 Not more than 3 cm from fourchette and 2.5 cm from anus

 

·                 Position the mother in lithotomy

 

·                 Wait one or two minutes after injection of local anesthesia

 

·                 Insert two flingers between the perineum with the fetal scalp

 

·                 Do the incision during a uterine contraction

 

·                 It should be deliberate cut

 

·                 The cut should be adequate to remove any resistance to fetal head

 

·                 May straight blunt painted scissors 17.5cm commonly used.

 

·                 Must be sharpened at frequent intervals 

 

Hints on repairing the perineum

 

·                 Should be sutured with in one hour after local analgesia given

 

·                 The area is cleansed with savalon solution

 

·                 For any leakage from the uterus, vaginal tampon or pack should be inserted

 

·                 Good light is essential

 

·                 The two extent of the laceration is determined

 

Controlling methods of bleeding after episiotomy

 

·                 Applying gauze swab on the area

 

·                 The pressure exerted by the fetal head

 

·                 If bleeding occurs after delivery – two Spencer wells forceps should be applied to the bleeding vessels.

 

Layers to be repaired

 

·                 Vaginal wound                     

o       Deep and superficial tissue

o       Vaginal mucosa

 

·                 Perineal muscles and fascia

 

·                 Perineal skin and subcutaneous tissue

 

The first stitch inserted at the apex of the incision The most commonly used suturing material is 2/0 chromic catgut.

 

 

Remember:

 

·                 Do not tie the sutures too tightly

·                 The last stitches are important for they prevent excessive scar.

·                 Press firmly on suture line with a pad to see if bleeding has stopped.

·                 Remove perineal pad or suture pack from vagina. Rub up fundus put clean pad on perineum

·                 Put gloved finger in to the rectum – to make suture that no stitch has one through the rectum

·                 Make the women comfortable, clean and dry.

 

 

After care of episiotomy

 

·                 Hot bath, clean wound care

·                 If pus or fouls smelling discharge develop report to health personnel

·                 Advise not to strain and avoid constipation

Lacerations

  Lacerations   A tear is called laceration. The tear can occur in the vaginal wall or in the perineum or in the cervix. Tears of the perineum are graded according to their severity. Other areas of trauma may be the cervix and extended tears of the vagina.   Causes   ·          Not controlling the head at delivery   ·          Precipitate labour   ·          Big baby   ·          Face to pubis and after coming head of breech   ·          Instrumental delivery   ·          Old scar tissue and face presentation   Type of perineal lacerations   First degree   Involves the vaginal mucous and the skin of the perineum.   Second degree   Involved the deeper layer of perineal muscle   ...

The origin of cell excitation

  The origin of cell excitation The mechanisms we have discussed above account for the propagation and for the termination of the action potential. However, so far we have relied on external electrodes for its initiation. Under physiological conditions, action potentials can be evoked in various ways. The first, very important means of action potential genera-tion consists in synaptic transmission. A synapse connects a presynaptic cell (always a neuron) to a postsynaptic cell (a neuron or muscle cell). In brief, a synapse works as fol-lows:   1.    Excitation of the presynaptic cell leads to the release of a neurotransmitter substance.   2.    The neurotransmitter binds to a receptor on the postsy-naptic cell, very commonly a ligand-gated channel.   3.    The receptor channel opens and locally depolarizes the membrane.   4.    The local depolarization is picked up by adjacent voltage-gated channels and propagated across th...
