摘要: Abstract Study Objective: To determine the feasibility of continuous caudal anesthesia with 2-chloroprocaine in conscious former preterm infants undergoing inguinal hernia repair. Design: Prospective study. Setting: University-affiliated children's hospital. Patients: Ten infants, ASA physical status II and III, who were 35 to 49.5 weeks postconceptional age at time surgery. Interventions: Caudal was administerd via an indwelling catheter using a loading dose 1 mllkg (30 mglkg) 3% 2-chloroprocaine, followed by incremental doses 0.3 ml/kg (9 mg/kg) achieve level T4 T2. The block maintained minimum infusion rate 30 mg/kg/hr (1 mllkglhr) same local anesthetic solution. Measurements Main Results: mean cumulative 2.8 ± 1.0 mllkglhr (84 mg/kg/hr) infused over duration 95 minutes. Serum cholinesterase concentration plasma measured five infants. Conclusions: Three percent can be used effectively for conscious, penoscrotal surgical procedures lasting 85 170
