[Caudal regional anesthesia: a safe anesthetic procedure for abdominal and inguinal surgery in newborns and toddlers].

OBJECTIVES

Caudal anesthesia is a safe and effective technique in children. Some surgical procedures, such as abdominal or inguinal surgeries, could be performed avoiding general anesthesia in newborns and babies, reducing the risk of respiratory depression and neurotoxicity. Our objective is to analyze the experience in a tertial referral center.

MATERIAL AND

METHODS

We carried a retrospective study in patients under 1 year of age who underwent abdominal or inguinal procedures under caudal regional anesthesia, between 2016 and 2018. Demographics, diagnosis, comorbidity, surgical procedure, operation time, oral intake, perioperative complications and hospital stay were recorded.

RESULTS

We included 87 patients under 1 year of age. In 56 patients (23 males, 33 females) surgery was performed under caudal anesthesia (37 scheduled, 19 urgent). Mean age was 2 months (0-11). Comorbidity: 25 associated prematurity, 3 severe tracheomalacia, 1 apnea and 8 bronchopulmonary dysplasia. Surgical procedures: 34 inguinal hernia repair, 9 incarcerated inguinal hernias, 5 neonatal testicular torsions, 8 pyloromyotomies. Mean operation time was 35 min (15-80) and mean anesthetic time 30 min (20-60). Oral intake started 2 h after surgery in 55 patients. Discharge was given in 24 h (12-36). Complications were not noticed. Any patient needed conversion to general anesthesia.

CONCLUSIONS

Caudal anesthesia should be the anesthetic technique of choice in newborns and babies who undergo abdominal or inguinal surgeries, especially in those with comorbidity. This procedure could be performed safely, avoiding respiratory or neurological complications, with a fast recovery of patients and short hospital stay.
