Insights

Surgery for very low birth weight infants is increasing. Careful anesthetic management is crucial due to their unique physiology and sensitivity to pain, requiring precise oxygen, hemodynamic, and temperature control.

Area of Science:

  • Neonatal Surgery
  • Pediatric Anesthesiology
  • Neonatal Intensive Care

Background:

  • Increasing surgical opportunities for very low birth weight (VLBW) and extremely low birth weight (ELBW) infants.
  • VLBW/ELBW infants are susceptible to prematurity-related morbidities and sensitive to pain and stress.
  • Limited understanding of drug pharmacokinetics in preterm infants necessitates tailored anesthetic approaches.

Purpose of the Study:

  • To outline key anesthetic considerations for surgical procedures in VLBW and ELBW infants.
  • To highlight the importance of specialized anesthetic management in this vulnerable population.

Main Methods:

  • Review of current evidence regarding anesthetic management in preterm infants undergoing surgery.
  • Focus on physiological characteristics and pharmacokinetic differences in VLBW/ELBW infants.

Main Results:

  • Preterm infants require smaller anesthetic doses with longer durations of effect due to immature clearance and elimination pathways.
  • Anesthetic management must prioritize controlled inspired oxygen to prevent hyperoxia.
  • Maintaining stable hemodynamic parameters is essential.
  • Active prevention and management of hypothermia are critical throughout the perioperative period.

Conclusions:

  • Anesthetic management for VLBW/ELBW infants requires meticulous attention to detail.
  • Continuous monitoring and adjustment of inspired oxygen, hemodynamics, and temperature are vital for optimizing surgical outcomes.
  • Safe transport to and from the operating theatre is an integral part of anesthetic care.

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
General Anesthesia: Overview01:24

General Anesthesia: Overview

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
