CYTARABINE (Ara-C)

Cytarabine is a pyrimidine analogue antimetabolite widely used in the treatment of acute leukemias, especially Acute Myeloid Leukemia (AML). Inside the cell, it is converted to Ara-CTP, which incorporates into DNA and inhibits DNA polymerase, leading to chain termination and apoptosis. It is most active in the S-phase of the cell cycle.

🔹 Class

Antimetabolite – Pyrimidine analogue

🔹 Subclass

Pyrimidine antagonist

🔹 Mechanism of Action (MOA)

Converts to Ara-CTP, the active metabolite

Inhibits DNA polymerase

Incorporates into DNA → chain termination

Blocks DNA replication

Induces programmed cell death

Cell cycle–specific (S-phase)

🔹 Indications

AML induction (7+3 regimen)

Acute Lymphoblastic Leukemia (ALL)

CML blast crisis

CNS prophylaxis/therapy (intrathecal cytarabine)

🔹 Dosage

Intrathecal: 20–50 mg, age-based

🔹 Side Effects

✅ 1. Objectives of Premedication
1. Relief of Anxiety & Fear

Surgery causes stress. Anxiolytics calm the patient, reduce sympathetic activity, and make induction smoother.

2. Sedation

Light sedation helps the patient remain cooperative and relaxed.

3. Analgesia

Provides pain relief before induction, especially in trauma or emergency cases.

4. Reduction of Secretions

Control of salivary and airway secretions reduces the risk of aspiration and eases airway management.

5. Prevention of Nausea & Vomiting (PONV)

Anti-emetics prevent postoperative nausea and vomiting, a common anesthesia complication.

6. Aspiration Prophylaxis

Decreasing gastric acid volume and acidity protects the patient during induction, especially if they vomit.

7. Hemodynamic Stability

Certain drugs help control blood pressure, heart rate, arrhythmias.

8. Allergic Reaction Prevention

Steroids or antihistamines may be given in selected cases.

9. Facilitation of Smooth Induction

A calm, cooperative patient ensures easy IV cannulation and airway management.

🧪 2. Drugs Used for Premedication
A. Sedatives & Anxiolytics

Used to reduce anxiety and induce mild sedation.

Common Drugs:

Midazolam (most common)

Diazepam

Lorazepam

📌 Given 30–60 minutes before surgery.
📌 Avoid excessive sedation in elderly, COPD, OSA patients.

B. Analgesics

Provide pain relief and blunt hemodynamic response.

Common Drugs:

Fentanyl (short-acting opioid)

Morphine (less used pre-op due to long action)

📌 Used carefully to avoid respiratory depression.

C. Anticholinergics

Reduce secretions and prevent bradycardia.

Common Drugs:

Glycopyrrolate (preferred; does not cross BBB)

Atropine

Indications:

Pediatric anesthesia

Pre-intubation to reduce secretions

Prevention of vagal bradycardia

D. Anti-emetics

Prevent postoperative nausea and vomiting.

Common Drugs:

Ondansetron

Metoclopramide

Dexamethasone (also reduces edema)

E. Aspiration Prophylaxis

Used especially in emergency or full-stomach patients.

Drugs:

Ranitidine (H₂ blocker)

Pantoprazole (PPI)

Sodium citrate (neutralizer)

📌 Reduces gastric acidity and volume.

F. Antibiotics

Given prophylactically before surgery.

Examples:

Ceftriaxone

Cefazolin

G. Others (Selective Use)

β-blockers (Metoprolol) – for cardiac stability

Steroids – for airway edema, allergic patients

Bronchodilators – for asthmatics

Insulin – for diabetic patients

📝 3. Assessment Before Premedication

Before giving any premedication, check:

A. Patient Evaluation

Age

Weight

Comorbidities

Allergies

Current medications

B. Airway Assessment

Mallampati score

Neck mobility

Mouth opening

C. Fasting Status

Ensure proper NPO guidelines:

2 hours – clear liquids

6 hours – light meals

8 hours – fatty meals

D. Baseline Vitals

HR, BP, RR, SpO₂

E. Psychological State

Anxiety level

Requirement for sedation

⚠️ 4. Contraindications of Premedication

Avoid or modify premedication in:

Severe respiratory depression

Uncontrolled asthma

Shock

Elderly (risk of over-sedation)

Obstructive sleep apnea

Morbid obesity

🩺 5. Advantages of Proper Premedication

Calmer patient

Reduced risk of aspiration

Better control of airway

Smoother induction

Less postoperative nausea

Reduced surgical stress response

Improved overall outcome

National Anaesthesia and OT Technologist Day 20th of July
🩺💉🛌⚙️

Every year, National Anaesthesia and Operation Theatre (OT) Technologist Day is observed to recognize the vital role these healthcare professionals play in the surgical ecosystem. It is a day to honor the dedication, expertise, and behind-the-scenes work of Anaesthesia Technologists and OT Technologists who ensure that every operation is safe, smooth, and successful.

🩺 Who are Anaesthesia and OT Technologists?
Anaesthesia Technologists assist anesthesiologists in preparing and managing anaesthetic equipment, monitoring patients during procedures, and ensuring patient safety before, during, and after surgery.

OT Technologists are responsible for maintaining a sterile environment, setting up surgical instruments, assisting surgeons during operations, and managing OT logistics.

💡 Why Celebrate This Day?
To acknowledge their critical contribution to surgical teams.

To raise awareness about their profession and encourage future healthcare workers to join the field.

To celebrate excellence in patient care, safety, and innovation in operation theatres.

🔧 Their Roles Include:
Preparing and maintaining anaesthesia machines, monitors, and emergency equipment.

Supporting patient positioning and prepping in the OT.

Assisting with airway management and vascular access.

Ensuring infection control and sterile procedures are strictly followed.

🙏 A Salute to the Unsung Heroes
Often working behind the scenes, Anaesthesia and OT Technologists are essential for life-saving surgeries and critical care procedures. This day is a tribute to their tireless efforts, skill, and dedication.

A short notes on Atropine.

Cardiopulmonary bypass:
Cardiopulmonary bypass is a procedure that diverts blood circulation away from your heart and lungs. It’s a routine part of many heart surgeries. “Cardio” refers to your heart, and “pulmonary” refers to your lungs. “Bypass” means to avoid something by going around it. So, cardiopulmonary bypass allows your blood to avoid your heart and lungs during your surgery.
Another name for cardiopulmonary bypass is being “on the pump.” Usually, if you’re on the pump, your surgeon will also use medication (cardioplegia solution) to stop your heart from beating. Cardiopulmonary bypass with cardioplegia allows your surgeon to perform surgery on a still (non-beating) heart. This procedure also allows the rest of your body to receive the oxygen-rich blood it needs to survive.

Indication:

Coronary artery bypass grafting (CABG).
Aneurysm surgery.
Heart transplant.
Heart valve surgery.
Lung transplant.

Working of cardiopulmonary bypass:

Blood from your superior and inferior vena cava drains into tubes that connect to the machine’s reservoir.
The blood passes into the oxygenator, where it gains oxygen.
The machine pumps the blood back into your body through a tube connected to your aorta. The aorta is where your blood would normally enter after finishing its journey through your heart and lungs.

key responsibilities include:

Draining blood from your heart.
Adding oxygen to your blood and removing carbon dioxide.
Managing your blood’s temperature and electrolyte levels.
Pumping oxygen-rich blood back into your body.
Delivering medication that temporarily stops your heart.
Protecting your heart throughout the surgery.
Suctioning away and saving blood that’s lost during the surgery

Parts of a cardiopulmonary bypass machine:

Tubes that connect your blood vessels to the machine
Reservoir.
Oxygenator.
Pump.

To conduct cardiopulmonary bypass, perform the following steps:

Remove air from the heart-lung machine by filling its tubes with priming solution or compatible blood.
Give you a blood-thinning medication called heparin to lower your risk of blood clots..
Connect you to the heart-lung machine.
Stop your heart and lungs.
Monitor you during your surgery.
Wean you off the machine.

Advantages of cardiopulmonary bypass:

Cardiopulmonary bypass allows body to receive oxygen-rich blood during the surgery. It takes over the work of heart and lungs so that surgeon can work in a still and bloodless space.

Complications:

Air embolism.
Bleeding.
Blood clots.
Brain injury.
Inflammation throughout your body.
Lung injury.
Kidney injury or kidney failure.
Multi-organ failure.
Pancreatitis.
Pleural effusion.
Stroke.
