[Changes in hemodynamics with a combination of epidural anesthesia and propofol sedation in children]
Insights
Epidural anesthesia with propofol in children (3-14 years) provided stable hemodynamics and good analgesia. However, this anesthesia approach was associated with a moderate decrease in myocardial contractility.
Area of Science:
- Pediatric Anesthesiology
- Cardiovascular Physiology
- Pharmacology
Context:
- Epidural anesthesia combined with intravenous propofol is utilized in pediatric surgical procedures.
- Hemodynamic stability and myocardial function are critical considerations in pediatric anesthesia.
- Assessing the impact of anesthetic agents on cardiovascular parameters in children is essential.
Purpose:
- To investigate the hemodynamic profiles and myocardial contractility in pediatric patients (3-14 years) undergoing epidural anesthesia with propofol.
- To evaluate the safety and efficacy of a combined epidural and intravenous propofol anesthesia technique.
- To determine the effects of this anesthetic regimen on cardiac function in children.
Summary:
- Children (3-14 years) received intravenous propofol for induction, ketamine for intubation analgesia, and Xilocaine for epidural analgesia.
- Anesthesia was maintained with continuous intravenous propofol, adjusted based on epidural analgesic activity.
- This technique resulted in hemodynamically stable anesthesia and effective analgesia for complex surgeries.
- A moderate decrease in myocardial contractility was observed during this anesthetic approach.
Impact:
- The findings suggest that while epidural anesthesia with propofol offers hemodynamic stability and analgesia in pediatric surgery, clinicians should monitor myocardial contractility.
- This study provides valuable data for anesthesiologists regarding the cardiovascular effects of this specific anesthetic combination in children.
- Further research may explore strategies to mitigate the observed decrease in myocardial contractility while maintaining anesthetic benefits.
Abstract:
Hemodynamic profiles and myocardial contractility were investigated in children aged 3-14 years during epidural anesthesia with propofol. Anesthesia was induced by intravenous bolus propofol (3.5 mg/kg). Ketamine (2.4 mg/kg) was used to potentiate analgesia during intubation. Xilocaine (5 mg/kg) was used for epidural analgesia. Anesthesia was maintained by continuous i.v. propofol infused in a dose of 191-312 micrograms/kg x min (mean dose 243 +/- 30.3 micrograms/kg x min) until the peak of epidural analgesic activity was reached, after which propofol dose was gradually reduced to 53-143 micrograms/kg x min (mean 108.8 +/- 14.6 micrograms/kg x min). This variant of epidural anesthesia with i.v. propofol ensured a hemodynamically stable anesthesia and good analgesia in operations of any complexity. It was however paralleled by a moderate decrease of myocardial contractility.
