IV Cannula lagane ka procedure + Direct IV Injection
Hinglish guide for trained healthcare staff/students. Patient par practice sirf supervision aur hospital protocol ke according karein. Drug ka dose, dilution aur push rate hamesha prescription, drug label aur local policy se verify karein.
1. IV Cannula Insertion
Required items
- IV cannula, suitable size
- 18G: blood/rapid fluid or surgery
- 20G: most adults
- 22G/24G: elderly, children, fragile veins
- Tourniquet
- Hand rub/soap-water
- Gloves
- Skin antiseptic: usually alcohol-based chlorhexidine, as per hospital policy
- Sterile gauze/cotton
- Normal saline flush
- Extension set/needle-free connector or IV set
- Transparent sterile dressing and tape
- Sharps container
- Label with date/time/initials
Site selection
- Prefer distal upper-limb vein first: dorsum of hand or forearm.
- Avoid:
- infected, burnt, bruised, swollen, painful or scarred skin
- areas of flexion such as wrist/antecubital fossa if another option is available
- limb with AV fistula, lymphoedema, or after axillary lymph-node surgery unless specifically permitted
- limb with impaired circulation.
- Choose the smallest cannula that can safely deliver the prescribed therapy.
Step-by-step
-
Prescription check karo
Patient ki identity with 2 identifiers verify karo. Procedure explain karo, consent/cooperation lo, allergies check karo.
-
Hand hygiene karo
Alcohol hand rub ya soap-water use karo. Equipment prepare karo.
-
Patient ko position do
Limb ko comfortable support do. Arm ko dependent position mein rakhne se veins better dikhti hain.
-
Tourniquet lagao
Proposed site se about 7-10 cm above lagao. Radial pulse absent nahi hona chahiye. Patient se fist clench karwa sakte ho, pumping avoid karo.
-
Vein identify karo
Vein ko inspect/palpate karo. Suitable vein select karne ke baad tourniquet loose mat karo unless needed.
-
Skin antisepsis
Gloves pehno. Site ko antiseptic se clean karo and completely air-dry hone do.
Clean karne ke baad vein/site ko dobara touch mat karo. If touch karna pade, aseptic technique maintain karo.
-
Cannula insert karo
- Cannula bevel up rakho.
- Skin ko vein ke neeche gently taut karo.
- About 10-30° angle par vein enter karo.
- Flashback blood chamber mein dikhte hi angle aur shallow karo.
- Needle ko thoda advance karke plastic catheter ko vein mein advance karo.
- Tourniquet release karo.
- Vein ko cannula tip ke proximal side par gentle pressure se occlude karo.
- Needle/stylet ko completely remove karke immediately sharps container mein daalo. Needle ko reinsert kabhi mat karo.
-
Cannula secure karo
- Extension set/needle-free connector attach karo.
- Saline flush se patency check karo, local policy ke according.
- Pain, resistance, swelling, leakage, ya coolness ho to flush stop karo.
- Transparent sterile dressing lagao. Site visible rehna chahiye.
- Date, time, cannula size aur initials label karo.
-
Document karo
Site, gauge, number of attempts, patient response, flush/patency, and any complication chart karo.
WHO catheter guidance emphasizes hand hygiene and aseptic no-touch technique during insertion, maintenance, access, and removal. The
CDC recommendations also state that the site should not be palpated after antiseptic application unless asepsis is maintained.
2. Direct IV Injection / IV Push
Pehle safety checks
- Right patient
- Right medicine
- Right dose
- Right route
- Right time
- Allergy status check
- Expiry date, clarity of drug, compatibility and dilution check
- Drug ko IV push dena allowed hai ya nahi, aur kitne rate se dena hai, reliable drug reference/local protocol se confirm karo.
Har medicine IV push nahi di ja sakti. Kuch medicines dilute karni padti hain, kuch slow IV push hoti hain, aur kuch infusion pump se deni hoti hain. Guess karke kabhi IV push mat dena.
Equipment
- Prescribed drug syringe, properly labeled
- 0.9% normal saline flush syringes, as per policy
- Alcohol/antiseptic swab
- Gloves
- Drug reference/chart
IV Push technique: S-A-S-H concept
S = Saline flush
A = Administer medicine
S = Saline flush
H = Heparin flush, only if device/order/protocol requires it. Peripheral cannula mein normally heparin routine nahi hota.
Step-by-step
-
Patient ko explain karo
Side effects and sensation explain: “Burning, pain, dizziness, breathlessness, itching ho to immediately batana.”
-
Hand hygiene and gloves
Hand hygiene karo. Gloves pehno.
-
IV site assess karo
Site par redness, pain, swelling, leakage, warmth/coolness, hard vein, discharge check karo.
Agar abnormality hai, IV push mat do.
-
Connector/port disinfect karo
Needle-free port ko approved antiseptic swab se scrub karo and dry hone do. Local policy ka scrub time follow karo.
-
Patency check karo
- Syringe attach karo.
- If your protocol permits, gently blood return assess karo.
- Normal saline se gentle flush do.
- Resistance, pain, swelling, leakage, or no flow: stop. Force mat karo.
-
Drug administer karo
- Drug syringe attach karo.
- Prescribed rate ke hisaab se slow push do.
- Patient ko continuously observe karo.
- Injection ke waqt pain, burning, swelling, chest discomfort, rash, wheeze, dizziness, or altered consciousness ho: immediately stop.
-
Post-flush
- Drug syringe remove karo.
- Compatible normal saline flush do, ordered/local protocol ke according.
- If multiple IV medicines: compatibility check karo and each medicine ke beech appropriate saline flush do.
-
Aftercare and documentation
- IV site recheck karo.
- Patient response/side effects assess karo.
- Drug name, dose, route, time, dilution, rate, IV site/patency, and your signature document karo.
3. Kab injection turant rokna hai?
Stop IV injection/infusion immediately if:
- Pain, burning, swelling or tightness at site
- Leakage around cannula
- Site cool/pale or warm/red
- Resistance during flush or injection
- Red streaking, tender/hard vein
- Rash, itching, facial swelling, wheeze, breathlessness
- Sudden hypotension, severe dizziness, chest pain, altered sensorium
Then: keep patient safe, assess vitals, inform senior/doctor, and follow extravasation or anaphylaxis protocol as appropriate. Do not flush a suspected extravasation site unless the specific protocol says to do so.
The CDC advises removing a peripheral IV if there are signs of phlebitis, infection, or device malfunction, including warmth, tenderness, erythema, or a palpable venous cord (
CDC guidance).
4. Common mistakes avoid karo
- Unlabelled syringe use karna
- Medicine ka dilution/push rate check na karna
- Cannula ko pain/resistance ke bawajood force flush karna
- Skin prep ke baad site ko touch karna
- Needle ko recap karna
- Same IV line mein incompatible drugs mix karna
- Cannula site inspect kiye bina direct injection dena
- Cannula ko necessary na hone par bhi leave karna
Short memory line
“Check - Clean - Cannulate - Confirm - Secure - Flush - Give slowly - Flush - Observe - Document.”
For infection prevention, refer to the
WHO peripheral catheter guideline, which covers insertion, maintenance, access, and removal of peripheral IV catheters.Yeh 4 categories
fixed nahi hoti. Same medicine ka route vial strength, patient age, kidney function, indication, hospital policy, and manufacturer instructions ke hisaab se change ho sakta hai. Isliye
ampoule/vial ka label + hospital IV drug chart/pharmacist reference dekhe bina kabhi decide mat karo.
Rule: “IV dena hai” ka matlab automatically “direct push” nahi hota.
1. Direct IV push via cannula: kaunsi medicines?
Kuch medicines ready-to-use form mein, prescribed slow IV push rate ke saath di ja sakti hain. “Direct” ka matlab bhi aksar slow push over several minutes hota hai, ekdum jaldi push nahi.
| Common examples | Important point |
|---|
| Ondansetron | Usually slow IV injection, local protocol/label ke rate se |
| Metoclopramide | Often slow IV administration |
| Dexamethasone | IV push may be permitted depending on formulation |
| Hydrocortisone | Reconstitute karke slow IV injection possible in some preparations |
| Furosemide | Slow IV push only, rapid push unsafe ho sakta hai |
| Tranexamic acid | Slow IV injection, never rapid push |
| Pantoprazole | Specific product instructions follow karein, often slow IV injection/reconstituted form |
| Calcium gluconate | Slow IV, ECG monitoring may be needed in higher-risk situations |
| Adenosine | Special emergency drug: rapid bolus with immediate saline flush, only trained staff and monitoring |
High-risk medicines: potassium chloride, insulin, opioids, sedatives, antiarrhythmics, anticoagulants, chemotherapy, concentrated electrolytes. Inhe casually direct IV push nahi dena chahiye.
2. NS mein dilute karke syringe se slow IV push: kaunsi medicines?
Kuch drugs ko syringe mein 0.9% normal saline (NS) se dilute karke prescribed time mein push diya jata hai. Lekin diluent aur final volume har drug ke liye same nahi hote.
| Common examples | Notes |
|---|
| Ceftriaxone | Reconstitute/dilute only as product instructions allow; avoid mixing with calcium-containing solutions |
| Cefotaxime | Reconstituted IV slow injection or infusion, depending on order |
| Meropenem | Usually reconstituted then slow IV injection or infusion |
| Piperacillin-tazobactam | Usually reconstituted and administered as infusion; not routine casual push |
| Vancomycin | IV push bilkul nahi. Dilute karke controlled infusion only |
| Phenytoin | Must use NS only, not dextrose; slow rate and monitoring required |
| Levetiracetam | Usually diluted and infused, not routine bedside IV push |
| Magnesium sulfate | Typically dilute and infuse slowly; emergency contexts follow specific protocol |
| Calcium gluconate | May be diluted depending on setting/order; slow administration and monitoring |
Very important
- “NS compatible” hone ka matlab yeh nahi ki drug direct syringe push kar sakte hain.
- Some drugs D5W mein compatible hoti hain, NS mein nahi.
- For example, phenytoin has special compatibility requirements, whereas other medicines have different diluents. Har drug ko NS mein dilute karna correct nahi.
3. Kaunsi medicines “direct drip” mein di jati hain?
“Direct drip bottle mein medicine dalna” technically risky wording hai. Safe practice mein preferably pharmacy-prepared infusion, premixed bag, minibag, syringe pump, ya correctly labeled dedicated infusion use hota hai.
Common medicines given as IV infusion
| Medicine/class | Usually how given |
|---|
| Vancomycin | Diluted IV infusion only, prescribed duration over |
| Metronidazole | Often premixed IV infusion bottle/bag |
| Paracetamol IV | Ready-to-use infusion bottle/bag, do not add other drug |
| Mannitol | Ready-to-use infusion, inspect for crystals first |
| IV fluids: NS, RL, D5, DNS | Drip as prescribed |
| Oxytocin | Diluted in compatible IV fluid and controlled infusion |
| Insulin infusion | Prepared in prescribed fluid and run with infusion pump/protocol |
| Heparin infusion | Pump-based infusion with strict protocol |
| Nitroglycerin infusion | Infusion pump and monitoring |
| Noradrenaline/adrenaline infusion | Critical-care infusion pump, not routine ward drip |
| Dopamine/dobutamine infusion | Pump with monitoring |
| Midazolam/propofol infusion | Monitored setting/pump, not simple bottle drip |
| Amphotericin B | Special dilution and long controlled infusion, formulation-specific |
Premixed infusion bottles, such as IV paracetamol or metronidazole, mein usually kisi aur medicine ko mix nahi karna chahiye unless pharmacy/compatibility reference specifically permits it.
4. Kaunsi medicines dilute karke bottle/bag mein dali jati hain?
Common examples, but only after checking exact compatible diluent, final concentration, infusion time and stability:
| Drug | General administration category |
|---|
| Ceftriaxone, cefotaxime, cefepime | Reconstitute then IV infusion, depending on order/product |
| Piperacillin-tazobactam | Diluted IV infusion |
| Meropenem/imipenem | Reconstituted then infusion, stability matters |
| Vancomycin | Must be diluted and infused slowly |
| Fluconazole | Often supplied as ready infusion or prepared per label |
| Ciprofloxacin/levofloxacin | Often premixed infusion, do not add to another bottle |
| Metronidazole | Often premixed infusion |
| Potassium chloride | Always dilute and infuse with controlled rate. Never IV push. |
| Magnesium sulfate | Dilute and infuse according to indication/protocol |
| Calcium gluconate | Controlled slow IV administration/infusion depending on setting |
| Aminophylline | Controlled slow infusion, not rapid push |
| Proton-pump inhibitors such as pantoprazole | May be slow injection or infusion depending on indication and product instructions |
Medicines that should never be casually direct IV pushed
- Potassium chloride (KCl): never IV push. It can cause fatal arrhythmia/cardiac arrest.
- Vancomycin: never IV push. Needs dilution and controlled infusion.
- Phenytoin: never rapid push, needs strict rate, NS compatibility and cardiac monitoring.
- Insulin: never IV push except a specifically ordered emergency protocol.
- Concentrated magnesium/calcium: not casual rapid push.
- Noradrenaline, dopamine, nitroglycerin, heparin: infusion pump and protocol.
- Chemotherapy/vesicant drugs: specialist handling only.
- Any medicine marked “for infusion only.”
Safe decision method before every IV medicine
- Prescription mein route dekho: IV push, slow IV, intermittent infusion, or continuous infusion.
- Drug ka exact name, strength and formulation verify karo.
- Check: dilute karna hai ya nahi, kis fluid mein, kitne mL mein.
- Check: kitne minutes mein dena hai.
- Check compatibility: NS, RL, D5W, existing running fluid, and other medicines.
- IV cannula site patency check karo.
- Syringe/bag par patient name, drug, dose, diluent, time and preparer label karo.
- High-alert medicines ke liye independent double check lo.
ISMP guidance says IV-push medicines should have clear preparation and administration instructions, and unnecessary bedside dilution can cause contamination and dosing errors. It also advises not to use infusion bags as common-source containers or to prepare flushes for multiple patients (
