Insights
Awake caudal anesthesia using bupivacaine and clonidine in former preterm infants may cause respiratory complications like apneas. Careful dose and drug selection are crucial for safe anesthesia in this vulnerable population.
Area of Science:
- Pediatric Anesthesiology
- Neonatal Surgery
Background:
- General anesthesia in former preterm infants for inguinal hernia repair carries risks of respiratory complications.
- Awake regional anesthesia, specifically caudal anesthesia, is an alternative to mitigate these risks.
- Caudal clonidine is explored to extend anesthesia duration and reduce postoperative pain.
Observation:
- A case report details two caudal anesthetics in a former preterm infant within three weeks.
- The first procedure at 35 weeks postconceptional age, using bupivacaine 0.25%, was uneventful.
- The second procedure at 38 weeks, with bupivacaine 0.125% and clonidine, resulted in intra- and postoperative apneas.
Findings:
- Inadvertent administration of a lower concentration of bupivacaine combined with clonidine led to significant respiratory events (apneas).
- This case highlights potential risks associated with caudal clonidine, even at reduced bupivacaine concentrations, in former preterm infants.
- The safety profile of caudal clonidine in this population warrants further investigation.
Implications:
- Clinicians should exercise extreme caution when using caudal clonidine in former preterm infants undergoing surgery.
- Dosage and drug combinations need careful consideration to avoid adverse respiratory events.
- Further research is necessary to establish safe and effective anesthetic protocols for this high-risk group.
Abstract:
Awake regional anaesthesia for inguinal hernia repair in former preterm infants is suggested to avoid life-threatening respiratory complications known to occur after general anaesthesia. Caudal anaesthesia is becoming a more popular technique for this purpose. To prolong duration of anaesthesia and to reduce postoperative need for analgesics in these infants, caudal clonidine has been considered useful. We report a former preterm infant, who had two awake caudal anaesthetics for herniotomy within 3 weeks. The first was uneventful with bupivacaine 0.25% at 35 weeks postconceptional age. At 38 weeks, the baby suffered form intra- and postoperative apnoeas after inadvertent administration of bupivacaine 0.125% plus clonidine.

Local Anesthetics: Clinical Application as Epidural Anesthesia
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...
