Urether catheterization, Nasogastric tube insertion
Year 2013-2014 / 2nd semester
Surgical vein preparation
Seldinger technique (central vein insertion, arterial and venous
cathetarization)
Surgical vein preparation I.
Aim: to ensure a stable venous rout for fluid replacement, drug administration and parenteral feeding in case of insufficient peripheral veins
Implementation:
•Performed by surgeon; aseptic (operathing theatre) environment
•Under general anaesthesia (if containdicated: strong pain killers and infiltration of local anaesthetic)
•Skin incision above a superficial vein, blund dissection of soft tissues, free dissection of the vein, small incision on the vessel, introduction of the catheter)
Surgical vein preparation II.

Seldinger technique I.Application: minimally invasive proceduresE.g.:1. Common Interventional Radiology Procedures: - procedures on arteries: angiography; percutaneous
transluminal angioplasty; arterial stenting, tu. embolisation..stb)
- procedures on veins: TIPS; thrombolysis in DVT; varicocele embolization, port insertion )
3. Central vein insertion (fluid replacement, drug administration and parenteral
feeding, intensive care monitoring etc)
Implementation: with palpation of the pulse or by means of ultrasound guidance
Insertion place:Arteries: femoral or brachial artery (less frequently: the radial or the popliteal artery) In case of veins: common femoral vein, internal jugular or subclavian vein
Seldinger technique II.
Venous portEmbolisation of uterinal artery
Seldinger technique III.1. Insert Braunüle into the lumen of the vessel
3. Flexible guidewire into the central vein
5. Dilation device
6. Central vein canula
2. Remove the needle
4. Remove the sheat of Braunüle
Removal of guide wire
Note: In case of special, so called Seldinger needle, the 1st and 2 nd steps are the same, because there is no plastic sheat

Urinary system monitoring
Catheterization of the bladder
Urether catheterization
Definition: artificial emptying of the urinary bladder.
Aims: therapeutic (urine retention, incontinence, preoperative preparation) diagnostic (monitoring fluid status, urologic/microbiologic tests)
Principles of catheterization
- catheterize only if it is necessary - avoid catheterization in case of urethral injuries - catheterize in accordance with the rules of asepsis!
Catheters
Material: synthetic, latex or silicone.Size: external diameter is given in Charriére (1 Ch) or
1 French (1 F) (=0.33 mm)The most widely used: 14-22 Ch Foley-catheter (with
balloon, easy fixation).
Tools for catheterization
- catheter in appropriate size- urine container sack and tube- sponges for cleaning of genital area- disinfectant- saline (in syringe) to fill the balloon- sterile lubricant (Instillagel)- sterile gloves
Male catheterization
Removing the catheter in males
Male catheterization- Lift the penis (about 60 degrees) with left hand
and retract the foreskin- Clean the urethral meatus with disinfectant 3
times- Inject some Instillagel to the urethra- Insert the catheter into the urethra with
sterile forceps- Fill the balloon with 10 ml saline- Pull back the catheter until the balloon
allows- Connect the urine container sack to the
catheter.
Female catheterization
Female catheter removal
Female catheterization
- Spread the labia gently with left hand- Clean the introitus with disinfectant 3 times- Grasp the catheter with sterile forceps at some cm-s
from the end - Put Instillagel onto the first some cm-s of the
catheter- Insert the catheter gently into the
urethra- Connect the urine container sack
to the catheter- Fill the catheter with 10 ml saline- Pull the catheter back.
Enteral Feeding
Nasogastric tube insertion
Enteral feeding1.Parenteral feeding2.Enteral feeding (tubes)
Planning: gastroenteral feeding is preferred beacause it is more physiological
Short term feeding(max. 2-3 weeks):
Nasogastric tubesOrogastric tubesNasoduodenal tubesNasojejunal tubes
Long term feeding(stomas):
OesophagostomaGastrostomaJejunostomaPercutan endoscopic gastrostomaPercutan endoscopic jejunostoma
Who needs an NG:
Assessment:•Surgical clients•Ventilated client•Neuromuscular impairment .•Clients who are unable to maintain adequate oral intake to meet metabolic demands.
Assess patency of nares.
„Indicated for those clients who do not want/ cannot/ must not eat”
Gather equipment for nasogastric tube insertion 14 0r 16 Fr NG tube
• Lubricating jelly• PH test strips• Tongue blade• Flashlight• Emesis basin• Catheter tipped syringe• 1 inch wide tape or commercial fixation device• Suctioning available and ready
Preparation of the patient (high Fowler position)
NG insertion-video
NG tube insertion I.– Inform the patient– Patient is laid in a fowler, or in a semi-fowler position (in case
of unconciuosness)
Semi-fowler position
NG tube insertion II.
– Handwash– Gloving– Assess the patency of the tube– Measure the required tube length (until the ear lobe
and the xyphoid process)– Preparation of the tube (bending, lubricant)
LubricantMeasure the length of the tube
– Introduce at an acute angle at first then push forward toward the nasopharynx
– After getting through the nasopharynx the patient should bend híds head
NG tube insertion III.
introduction After a few cm push parallel with the nose
• The patient take breath throuh his mouth during the whole procedure• Tube can get through the oropharynx during swelling (we pretend it
by moving the epiglottis on the manikin)
NG tube insertion IV.
• After getting through the oropharynx, check the location of the tube (in case of breathing sounds take it out)
• Introduce the tube gradually during every swelling
• Do not force the introcuction (in case of any obstruction take it out)
• Fix the tube with plaster around the nose

NG position
right
Checking:
Confirm satisfactory tube positioning before starting tube feed • aspirate for pH and color• Stetoscope• X-ray
Right product, right time, right client, right rate…..check and chart.
Monitor intake and output
check the position of the tube before every feeding (at least in every 12h)
