Atracurium
Atracurium is an intermediate-acting, non-depolarizing neuromuscular blocker. Hofmann elimination (independent of renal/hepatic function). Causes histamine release (risk of hypotension/tachycardia). Dose: 0.4-0.5 mg/kg IV. Reversed by neostigmine/glycopyrrolate. Ideal for patients with organ dysfunction.
Isoflurane
Isoflurane is a potent, reliable inhalational anesthetic (MAC ~1.2%) with moderate blood solubility (λB:G 1.4). Known for cardiovascular stability and bronchodilation, it uses a standard vaporizer. Pungent but less than Desflurane; suitable for pediatric maintenance. Cost-effective with minimal metabolism, making it a staple in anesthesia practice.
Desflurane
Desflurane is a potent inhalational anesthetic prized for its rapid emergence due to low blood solubility (MAC 6-7%). Ideal for outpatient surgery and fast wake-up needs. Requires a special heated vaporizer. Pungent and irritating, it’s contraindicated for inhalational induction. Minimal metabolism offers low toxicity risk. Key for anesthesia efficiency.
Sevoflurane
Sevoflurane is a potent, non-pungent inhalational anesthetic (MAC ~2%) with low blood solubility (λB:G 0.65). Ideal for smooth inhalational induction (especially pediatrics) and rapid emergence. Uses a standard vaporizer. Minimal airway irritation; monitor for Compound A with low-flow anesthesia. Low metabolism ensures safety.
Midazolam
Midazolam is a short-acting benzodiazepine used for preoperative sedation, anxiolysis, and amnesia. Rapid IV onset (1-2 min), metabolized hepatically. Causes respiratory depression; requires reversal with flumazenil. Synergistic with opioids. Key for procedural sedation and anxiolysis in anesthesia.
Thiopentone Sodium
The drug is a yellowish, hygroscopic powder, stabilized with 6% anhydrous sodium carbonate as a
Rocuronium
Rocuronium is a non-depolarizing steroidal muscle relaxant of intermediate duration. However, onset may be rapid or intermediate depending on the injected dose.
