Insights

Knowing the skin to epidural distance (SED) in children undergoing thoracic epidural anesthesia improves procedural success. This study found SED correlates with age and weight, offering guidance for this critical pediatric pain management technique.

Area of Science:

  • Pediatric Anesthesiology
  • Pain Management
  • Anatomical Measurements

Background:

  • Thoracic epidural anesthesia in children demands precise technique.
  • Success rates can improve with knowledge of the skin-to-epidural space distance (SED).
  • Accurate SED measurement is crucial for effective pediatric epidural procedures.

Purpose of the Study:

  • To measure the skin-to-epidural distance (SED) in anesthetized children undergoing thoracic epidural puncture.
  • To establish correlations between SED and pediatric patient characteristics.
  • To assess the utility of SED in guiding thoracic epidural needle placement.

Main Methods:

  • Observational study involving 61 anesthetized children.
  • Thoracic epidural puncture performed using the loss of resistance technique with saline.
  • Measurement of the distance from needle tip to skin emergence point.
  • Assessment of post-operative analgesia parameters.

Main Results:

  • Skin-to-epidural distance (SED) showed a significant correlation with both age and weight.
  • Developed predictive equations: SED (cm) = 2.15 + (0.01 x months) and SED (cm) = 1.95 + (0.045 x kg).
  • Considerable individual variability in SED was observed despite correlations.

Conclusions:

  • Skin-to-epidural distance is a valuable parameter for guiding thoracic epidural puncture in pediatric patients.
  • Age and weight are significant predictors of SED in children.
  • Incorporating SED measurements can enhance the precision and success of pediatric thoracic epidural anesthesia.

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...

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Pneumothorax II: Pathophysiology

Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...
Pneumothorax-I01:26

Pneumothorax-I

A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
