Buva Heavy Injection 0.5% + 8% contains Bupivacaine Hydrochloride and Dextrose. It is a long-acting local anesthetic used primarily for spinal (subarachnoid) anesthesia. The addition of dextrose makes the solution “heavy,” allowing controlled spread within the cerebrospinal fluid, which helps achieve a predictable and reliable anesthetic block during surgical procedures.

Composition

• Active Ingredients:
  • Bupivacaine Hydrochloride 0.5%
  • Dextrose 8%
• Dosage Form: Sterile injectable solution
• Route: Intrathecal (spinal) use only

Mechanism of Action

Bupivacaine works by blocking sodium channels in nerve membranes, preventing the initiation and transmission of nerve impulses. This results in reversible loss of sensation and motor function in the targeted region. The presence of dextrose increases the density of the solution, ensuring controlled distribution in cerebrospinal fluid and improving the predictability of spinal anesthesia.

Indications

Buva Heavy Injection is indicated for:

• Spinal anesthesia in lower abdominal surgeries
• Orthopedic procedures of lower limbs
• Urological surgeries
• Gynecological procedures
• Cesarean sections (under strict medical supervision)

Dosage and Administration

• Must be administered only by an experienced anesthesiologist
• Dose depends on patient condition, age, and type of surgery
• Administered via intrathecal injection into the subarachnoid space
• Continuous monitoring of cardiovascular and respiratory status is essential

Precautions

• Should only be used in a hospital setting with resuscitation facilities
• Use with caution in patients with cardiac, liver, or neurological disorders
• Risk of hypotension and bradycardia during spinal anesthesia
• Avoid overdose to prevent systemic toxicity
• Not recommended in patients with infection at injection site or bleeding disorders

Side Effects

Common side effects include:

• Hypotension
• Nausea and vomiting
• Bradycardia
• Headache after spinal anesthesia
